The new CR-V replacement 1.5T version and 2.0 hybrid version two power assembly, although the 1.5T version of the electric power brake system has exploded multiple fault cases, but the CR-V hot sale has increased , The phenomenon of increased decoration is still common, and the market performance can be described as hot.
The following is the basic information of the vehicle, and the car is added 5000 decoration.
At the beginning of the listing, Cr-V was exploded by the electric power brake system fault, and the case continued to increase, September 8 Dongfeng Honda released a recall announcement, launching recall, finally have a manner with users, expecting to repair one time The failure of the vehicle.
Section 1: Front protection
I often listen to question: What is the dismantling of the vehicle? What is the vehicle dismantling cover? For the new CR-V dismantling, talk about this topic.
The previous protective structure as an example, whether the dismantling is easy, can reflect the accuracy of each component in this structure, the quality of the fastening bolt connector, the process accuracy of the new car assembly, etc. After the installation, the left and right ends are easy to make up, and the silk cannot be seamless, and some models will not be disassembled, and there will be no packed situation when not using the card buckle bolt, and it is excellent.
Now, the card buckle connection has become quite common. Some models are disassembled in the injury, and some of the cards of some models are almost unpacking. The quality of these widgets is of course “cost”. .
Further, it is found that many bolts are discovered in the past, and the phenomenon of splitting, on the one hand, these plastic parts itself, on the other hand, the new car is controlled to “tighten torque” when the production line is assembled, these small The problem can certainly reflect the level of the host factory in the management of “process quality”.
Speaking here, can you say: If a car is removed after the repair, the closer to the new car can be restored, the process quality is better?
The new CR-V front protective structure includes four parts of the front bumper, low speed buffer, anti-collision beam and the suction box, and the lower part of the front bumper is set up, which can play a certain “pedestrian leg protection structure” role. .
The new CR-V front bar is relatively simple. The bottom guard plate is mainly in the card, and the snaps are basically no damage during the disassembly process. There are a little damage to the left and so on the left and right sides of the front bumper, which causes the vehicle to fill the body. In the front grid, the chrome-plated tribe is inlaid in the two-side headlights, and it must be particularly careful when disassembling, otherwise it is prone to damage. The current ambient temperature is relatively high, and if the cold winter is disassembled, the chrome-plated trim strip in the four-wheeled eyebrows and front grilles is more likely to occur. Of course, we don’t rule out the 4S shop Messenger disassembly technology is more skilled or avoiding these damage.
The internal structure of the front bum is relatively simple, the lever is soft, and if the front side is impact, if there is no support, it is more serious due to its rear, and most vehicles have this situation.
The new CR-V low speed buffer layer adopts a thin metal plate material, and the metal plate rolled the cap type groove to improve the body strength, which is worth mentioning that the new CR-V and Fit are the same, its low speed buffer layer is an integral, which is covered. The whole pre-collision beam, and the XR-V and Bang’s low-speed buffer layers are left and right, and there are approximately a vacancy of about one license plate length.
As shown in the figure above, the steel sheet under the new CR-V low speed buffer layer is inclined upward, and when the front impact is encountered, the low speed buffer layer is deformed, absorbed the collision energy, and the final low speed buffer layer will be bonded in the front end of the front anti-column beam.
The new CR-V pre-collision beam and low speed buffer layers are equal to long, metal, double-port type closed structure.
As shown in the figure above, the front end plate of the front anti-collision beam also rolled two grooves, improved the strength of the front end steel sheet itself, double-word shape provides a front-end steel plate to provide four longitudinal support, such a front anti-collision beam compared common.
The new CR-V suction box is a polygonal closed beam structure, metal material, and the tiles set a collapsed guidance. At present, the more common suction box is generally a quadrilateral bore structure.
The inner stringers in the Honda series models have always been such that not only the length is long, and the back is gradually pressed forward. What is the benefit of this form of wing panels? When encountering the front impact, this form of stringers can absorb collision energy by lower pressure deformation, without transmitting collision energy directly to the A column.
In the past, when I dismantled other models, we mentioned that the left and right sides of the front of the front side were: protection lacking area, if the front impact of the anti-collision beam, the collision energy broke through the front bumper and other accessories, the force is directly tire Wheel, etc., and Honda sets a lateral reinforcing structure at the front end of the wing plate, connecting the front stringers of the body, which is only reasonable, and the homewhere of the balance of the Honda is connected to the front of the body front. The strengthening structure will undoubtedly absorb more collision energy.
This time, the CR-V is 1.5T version, after taking off the front bumper, the electronically controlled air intake grille arranged at the front end of the water tank condenser appears, and the previously dismantled 2.4L four-wheel drive version did not see the part .
Leave it here for everyone: The purpose of setting the electric grille is nothing more than a fast hot car in cold winter, increasing parts is increasing cost, which also shows that the motor grill is necessary for 1.5T engine, but prior to 2.4 L The four-wheel drive model does not set this agency does not need itself? Still not thinking about it in this year? On this issue, the old CR-V robes in Northeast will have the most statement.
Editum:
The new CR-V pre-protection structure and the old model difference are different, and the middle of the front bumper has made local strengthening treatment, and it can play “equivalent leg protection” when colliding with pedestrians, this field is A good player who is good at dealing with “exam”.
Section 2: Rear protection
In terms of the front bumper, the new CR-V rear bumper is easier, but there is also a case where the rotor deformation damage is existed, and the fit with the body is not very good after the installation.
The rear bond is relatively simple, and the radar harness is arranged.
The rear bumper is improved, and the bellows becomes the main protective means, and the bare line is less.
After the new Cr-V, the anti-collision beam is a metal material, a cap type open structure, which is also a common form of collision beam.
In the previous dismantling, we also see the case of the anti-collision beam in front and rear, for example, before the anti-columns beam is a double-mouth shape closed structure, and then the anti-column beam is also a metal double-mouth shape closed structure. Of course The case where the protection is inconsistent before and after the vehicle is more common, depending on the relevant “requirements” and the host factory’s control for “cost”.
The suction cassette and front adapter cassette in the new CR-V rear protective structure are close, and the same is the same as a polygonal closed barrel structure.
Editum:
The new CR-V is also in accordance with the current mainstream level in the rear protection structure. The cap-type open anti-collision beam is more common, and the multilateral closing tube is relatively rare, and the suggescrapers in the rear protection structure of most models. Fashed, and even some models were reduced. At this point, CR-V is not bad.
Section III: Door Protection
The new CR-V front and rear car doors are splicing the door, and the door cavity uses a composite seal.
The inner side steel plate in front door is in the form of splicing, and the door splicing part is more beautiful.
The door of the door is close to the window of the window. The general model will set up the structure in the region, which has become auxiliary strengthening of door protection, but the new CR-V did not set this structure, which caused the hand to drop the door with hand and pulled the outer skin. Large deformation.
The composite protective structure of the front door inner tube beam + cap type reinforced ribs, which is also the current mainstream door protection form.
In addition, it is worth talking about the door cavity seal, and has not used the Japanese common plastic cloth, but it adopts plastic cloth + colored cotton seal. It is clear that this is to improve the tranquility of the car, for Cr The tranquility of the -v car is going to be CR-V riders more say.
The front door liner is provided with a native material white soundproof cotton.
The rear car door also uses a stitching door, the inner steel sheet is also splicing, and the door splicing part is more beautiful.
However, the rear door of the CR-V only sets the tubular beam. The strengthening of the strengthening of the front door is not behind the door. It seems that the new CR-V is very strong in cost control.
Not only that, the new CR-V back door outer skin also does not set up a strengthening structure, which means that it will have a large deformation amount in the outer skin of the back door.
Editum:
The new CR-V is very good in the performance of the door protection structure, but not only the back door is reduced, and the outer skin of the front door has not been set up. It seems that Honda is also working hard, obviously in the “compression cost”. This is not a good thing for consumers.
Section IV: Floor Protection
The new CR-V floor surface covers segmented felt, of course, more common is the integral felt, but the segmented flip will be slightly advantageous for the degree of installation.
The floor below the floor is regenerated, similar to sponge.
A large-area asphalt shock on the body bottom plate is also a common surface protection structure.
Editum:
Segmental felt, regenerated material filling pad, asphalt shock stickers constitute a new Cr-V floor protection, is clearly in terms of floor protection, the new CR-V performance does not have a colorful, because the test model is equipped with panoramic sunroof Therefore, it is not described herein about the roof content.
Section 5: Line Protection
In terms of vehicle line protection, the new CR-V performance is good. The main protection means of engine cabin lines are bellows, and the bare line is rare. At present, most models have consistent.
The new CR-V is equipped with Valta-free maintenance battery.
The new CR-V is close to the principle of the cockpit line protection level and the engine cabin protection level, the bellows are the main protection means, and the bare wiring is less.
The door line also rarely sees the naked wiring beam, the main wrapping material of the bellows + flannel is the harness, and the velvet package can also avoid the noise caused by vibration.
The new CR-V body peripherals are equally improved, and the bellows are the main protection means, and the bare harness is relatively rare.
Editum:
The new CR-V performance is excellent in the protection of the whole vehicle, especially compared with the German-style motor cabinet harness, the new CR-V is compared with the cockpit harness, or in the outer wiring of the body. In place.
Section 6: Chassis
Single on the bottom of the chassis guard area, the new CR-V is doing well, but the engine cabin is slightly cumbersome.
The engine cabin is used under the engine cabin, and a fluid hole is provided, which is advantageous for exhaust pipe radiation, and the front end of the metal plate is a non-metallic material front beam, and the rear non-metal guard is fixed to the body vertical Beams, three guards isolate the engine compartment with the ground.
The disassembly of the engine cabin is relatively easy, most of which are snaps, and the snaps are not damaged during the disassembly. When installing a metal guard, its snap lock is not very convenient, and it is easier to lock the mother button.
The new CR-V front sub-bracket is not in the full frame sub-frame, and the front-end transverse pipe beam is removed compared to the old CR-V full frame sub-frame, and it is replaced by a steel piece.
The advantage of the full frame sub-frame is the auxiliary framework for the frame structure of the front collision beam + front anti-collision beam + firewall, which can improve the front tissue stiffness and anti-mutory, and have a positive effect on the improvement of vehicle handling.
The front end of the left and soleter of the sub-frame is in the plane, and the reinforcing plate arranged at both ends of the left and so on the front front, which can be strengthened with the lower part of the front bumper, which can play a certain “preventing pedestrian involved in the bottom” role.
McPherson is also a common suspension form, the shock spring integral strut, the stabilizer cable is connected to the vibration damping pillar on both sides of the stabilizer, and the lower swing arm and the ball head are in the form of a split form, the lower swing arm is Double steel sheet rolled and soldered.
The new Cr-V used a multi-link independent venom, and the croissants were lightweight aluminum alloy materials, and the landscape stabilization rod was stored after multiple rods. For more dynamic performance of vehicles, click:“Dongfeng Honda CR-V failed to achieve the heart”
The spare tire grooves also set small-scale hair felt strips.
The new Cr-V multi-link after the unshaldion of the underlying arm also undertakes the role of the spring base, the shock absorber and the spring are separated.
As shown in the figure above, the heat insulating liner between the new Cr-V exhaust pipe and the body bottom plate is small, and a small piece is provided before the cockpit is provided, two of the fuel tank is provided.
The new CR-V fuel tank still retains the steel pipe protection framework, with a certain anti-collision effect, it is worth noting that the new CR-V gasoline position is low, in order to make up for this visual abrupt, the passenger is about two The guard is deliberately rulled down to ensure that the lower end face and the fuel tank are parallel, and the visual feeling of “smaller fuel tank is clearance”.
The above figure shows the heat insulating plate provided between the gasolipers and exhaust lines. The heat insulating liner is commonly used in the exhaust pipeline, which is more silver, and the new CR-V center muffler is a silver insulation liner. Sprayed with a metal plate close to the tank, which is relatively rare, as for the black coating on the heat insulating line, requires the time to test due to high temperature baking.
The new CR-V body chassis pipe is wrapped in the felt screen, rarely exposed, and the protection is in place.
Since the felt guard is provided under the crematic, the body bottom plate is only sprayed under the threshold of the left and right sides.
A hole opened on both sides of the central portion of the passenger cabin, set the sealed plug, and the rear wheel brake component correlation harness exported here.
In the case of opening and large area without spraying under the bottom plate, the vehicle is not recommended, otherwise there is leakage and rust risk.
Editum:
The new CR-V has been hanging from McFesson + a multi-connected rod, which is also a common suspension form in the price of the price. In terms of exhaust pipe, the new CR-V has obvious “compression cost traces. “, If users often travel in a humid region, and their chassis is necessary to do further treatment.
Section 7: Pingbian test
Interpretation:The new CR-V has been tested, and the results are as follows, and the author calls up the CS75, New H6 and Dongfeng Peugeot 4008 three car test data for the car.
Attached: NVH test
“NVH Test We use the” NVH Human Square Solution “This instrument is measured, we put the sensor above the seat cushion, the measters are sitting on the sensor, then on a measurement lane 60 km and 100 km. The speed of the speed separately, the last result we have to convert a time for our major users to understand. What is the working principle of “NVH human comfort measuring instrument”?
The road we have chosen is paved by a large stone plate. It can be said that we have made test conditions more bad, because the model we tested in the ordinary highway is not much, not much, see There is something special, there is basically more than twenty hours, so we take the initiative to strengthen the poor situation of the road, such numbers look more targeted and intuitive.
Some netizens suggest that we have tested in the gravel road. We also teach Tsinghua Teacher. They believe that the consistency of the gravel pavement is poor, and it cannot guarantee that each test car is rolled on the same section, then the collection of data reference is poor and cannot be done. The vehicle and other vehicles of Tsinghua ‘s self-test are paved on the same pavement, and the information feeds back from the roadbed can be exactly the same. In addition, don’t underestimate this brick pavement. Different vehicles are different. I really have a lot of testing skills that the vehicle is suspended, and the vehicle is driving in this road. Like the boat.
Section 8: Disclosure rating
The new CR-V final demolition is divided into 6.9 points.
