What should I do if the chassis is broken? How to repair the rotten chassis of the car

What should I do if the chassis is broken? Steel engine guards can be retrofitted. Some cars are equipped with engine guards.

If the car chassis is damaged, the car will be driven to the maintenance site according to different faults, such as the brake cylinder leakage brake fluid or the cylinder pipeline is broken, you can make a small pad with iron sheet and copper sheet at the joint of the pump pipeline, block the pipeline, and then tighten the screws, or flatten the fracture and curl the leakage, so that the wheel can not be braked. However, doing so may result in unilateral braking, so be careful when driving.

If the site is broken, you still have to find a manufacturer to sell it, I just look for the store where you bought it to give you after-sales.

Method:

1. If the brake sub-cylinder leaks brake fluid or the sub-pump pipeline is broken, you can make a small pad with iron sheet and copper at the joint of the sub-pump pipeline to block the pipeline, and then tighten the screw, or clamp the fracture flat, curl and plug the leakage, so that the wheel can not be braked. However, doing so may result in unilateral braking, so be careful when driving.

2. If the brake master cylinder lacks brake fluid, it can be replaced by alcohol or liquor, and under special circumstances, it can be replaced by clean water. Brake the leather bowl to swell, soak the swollen leather bowl in hot water for 10 minutes to 20 minutes, and remove the oily components on the leather bowl, so that the leather bowl can be restored to its original size.

3. The clutch friction plate is ablative and slippery, and the friction plate with less serious ablation can be turned over for use. If the ablation is severe, several layers of cotton cloth or canvas (the thickness of which should be consistent with the original friction plate) can be used, and steel wire or iron wire can be passed through the hole in the steel sheet to fix it. When driving the vehicle, you should start smoothly and change gears quickly.

4. If the ball joint of the tie rod is broken, remove a screw similar to the total length of the ball joint on the bumper or other places that do not affect the driving, replace the broken ball joint, install the knuckle arm and nut, and rivet the exposed part of the screw with a hammer.

If the three-axle differential gear is damaged, if either the middle and rear axle differential is damaged, the axle drive shaft and half shaft can be removed and continue driving. If the front differential is damaged, remove the hub engagement disc and continue driving.

Regarding the maintenance and fuel consumption of the automobile chassis, there are the following points:

1) The toe-in adjustment of the front wheels is appropriate. Inaccurate toe-in will increase the rolling resistance of the car and increase fuel consumption. Regularly check the toe-in value and compare it with the normal value, and adjust it if the value is different.

2) The bearing of Lunyi is well lubricated and properly adjusted. Poor grease and improper adjustment of bearing clearance will increase the driving resistance.

3) Pay attention to the changes in the front and rear axles and frames. Front and rear axle and frame displacement or bending deformation, make the body can not keep vertical or horizontal, when the car is driving, just deflect to a certain side, tire and ground sliding friction occurs, thereby increased driving resistance, make fuel consumption rise substantially.

4) Pay attention to whether the leaf spring is damaged. The damage of the leaf spring makes the car have poor driving balance, increases the driving resistance, and the fuel consumption also increases.

5) Brake clearance adjustment is appropriate. If the braking clearance is too small, the resistance will increase, and you must open the throttle to drive, which will increase fuel consumption; If the clearance is too large, the braking will not be effective, which will affect safety. Adjusting the brake clearance to avoid braking lag and clearance too large or too small also plays an important role in the sliding performance of the car.

6) Pay attention to the working condition of the clutch. The clutch is in poor working condition, and in the process of transmitting torque, there will be phenomena such as "shivering", "slipping", and "incomplete separation", which reduces the transmission efficiency and increases fuel consumption.

7) Pay attention to whether the tire pressure is normal. The type of tires used should be the same. According to statistics, if the tire pressure ratio decreases by 30%, the tire service life is shortened by 33% and the fuel consumption is increased by 6%.

You can separate the body from the frame and replace it with a new frame to connect the body. If it is a monolithic body, the body is rotten, and the extreme approach is to replace the body with a new one, and the parts on the old car are installed with a new body, and the transportation department can report it.

When carrying out the anti-rust work of the car, it should be noted that the use of anti-rust is best to use the same type of paint, so as to prevent different paint components from reacting with each other.

There are many parts under the chassis from front to rear, if they are scratched by stones, there are more damage to the lower edge of the bumper, damage to the engine guard, scratching of the cabin floor, scratching of the girder and local depression, damage or deformation of the exhaust pipe or muffler, as well as such as heat insulation plate fuel tank guard, etc., and even the suspension connecting rod is scratched;

For scratches and damages such as bumpers, engine guards, heat shields, protective plates, etc., they are generally repaired or directly replaced with new ones according to the situation;

Like scratching at the bottom of the carriage, if the deformation does not affect the others, do an anti-rust treatment, repair the damage and do anti-rust painting; If the girder scraping is only a local depression deformation but does not cause the overall deformation, it is also an anti-rust treatment.

Generally, in order to prevent damage to the chassis, 4S stores will recommend that the owner install engine guards on the car or protect the chassis commonly known as "chassis armor". After the engine guard is installed, the engine and gearbox, as well as the important parts located in the front chassis part, can be artificially protected, so that even if the bottom support situation does occur, it will contact the guard plate before it will not damage the important parts.

If the chassis of the sedan is rotten, you'd better go to the 4S shop to replace the partially rotten chassis, or add steel to the chassis.

Hello, the current number of people consulted may not reply in a timely manner, if it is a vehicle failure problem, it is recommended to use the computer to detect the specific cause of the failure, search for "car master" can consult car problems at any time, 24 hours ** answer.

If the car chassis is rusted, it is recommended that the owner go to a professional beauty shop for anti-rust care, and the anti-rust material should be evenly applied to the coating when the care is completed, and only wait for natural air drying after all is completed.

Automobile chassisThe automobile chassis is composed of four parts: the transmission system, the driving system, the steering system and the brake system. The role of the chassis is to support and install the automobile engine and its various components and assemblies, form the overall shape of the car, and accept the power of the engine, so that the car can move and ensure normal driving.

Summary. Hello, I am your exclusive technician, attentive, careful, dedicated to answering your car questions, for you to find the corresponding problem solutions and solutions!

It mainly depends on what accessories are damaged, and the general rubber sleeve can be damaged by changing the rubber sleeve alone, and the ball head must be replaced if the entire swing arm is broken.

After replacing the chassis parts of the car, a four-wheel alignment must be done to avoid the vehicle from deviating.

I hope my answer helps!

Hello, I am your exclusive book shouting technician, Qi Jing attentive, careful, concentrate on answering your car questions, for you to find the corresponding problem solutions and solutions! The relevant scheme is as follows: mainly to see what accessories are damaged The general rubber sleeve damage can be replaced alone The ball head is broken, the entire swing arm must be replaced, after replacing the automobile chassis accessories, you must do a four-wheel alignment, in order to avoid high posture and avoid vehicle deviation, I hope my answer can help you!
