Description

Technical Field

[0001] The utility model relates to vehicle engineering maintenance technology, in particular to an auxiliary clamp for vehicle engineering maintenance. Background Art

[0002] Automobile shock absorbers are an important part of the vehicle suspension system. They are responsible for reducing the bumps and vibrations during driving, providing a more comfortable ride experience, and also play a key role in the vehicle's handling and stability. As time goes by and the mileage increases, automobile shock absorbers may wear and age, and need to be replaced in time to ensure driving safety and ride comfort.

[0003] The following are the general steps for replacing the shock absorbers of your car:

[0004] Confirm the fault: First, you need to confirm whether there is a problem with the car's shock absorber. Common shock absorber failure manifestations include vehicle bumps, unstable suspension, excessive bouncing, etc. If these problems are found, you may need to consider replacing the shock absorber.

[0005] Choosing shock absorbers: Choose the appropriate shock absorber brand and model according to the vehicle brand, model and year. You can consult a professional auto repair shop or search and purchase online.

[0006] Prepare tools: Prepare the tools needed to replace the shock absorber, usually including a jack, wrench, screwdriver, etc.

[0007] Raise the vehicle: Use a jack to raise the vehicle and ensure that the vehicle is firmly supported on a safe stand to replace the shock absorber.

[0008] Remove the old shock absorber: Use tools to remove the old shock absorber, which usually requires removing the bolts and nuts connected to the shock absorber.

[0009] Install New Shock Absorber: Install the new shock absorber to the vehicle, making sure it is properly connected to the other components of the vehicle's suspension system and secured with the appropriate bolts and nuts.

[0010] Adjustment: Adjust the height and hardness of the shock absorber as needed to meet the requirements of vehicle driving performance and ride comfort.

[0011] Inspection: After installation, carefully check whether the shock absorber and surrounding connection parts are firm to ensure there is no looseness or oil leakage.

[0012] Lower the vehicle: Lower the vehicle from the stands, making sure the vehicle is stable.

[0013] Test: Carry out a test drive on the road to confirm whether the vehicle's driving stability and ride comfort are improved after the shock absorber replacement.

[0014] When the existing auxiliary clamps for vehicle engineering maintenance are used, there are still great deficiencies in the replacement of vehicle shock absorbers. When replacing the vehicle shock absorbers, especially the rear shock absorbers, the existing technology requires the vehicle to be lifted as a whole. At this time, the vehicle tires are suspended in the air, and the vehicle shock absorbers are in a stretched state. Both ends of the vehicle shock absorbers tightly hold the vehicle suspension. At this time, a jack is needed to support the suspension before the shock absorber can be removed. However, the vehicle is in a suspended state at this time. When a jack is used to support the vehicle suspension, the center of gravity of the vehicle will deviate, which may easily lead to the risk of vehicle overturning. At the same time, the jack will reduce the maintenance space of the maintenance worker and increase the difficulty of maintenance. Utility Model Content
