Car triangle arm action
The main role of the triangle arm of the car includes the following aspects :
Bear and disperse stress : the triangle arm can bear and disperse the transverse and longitudinal stress generated by the tire in the running process to ensure the stability and safety of the vehicle .
Connecting the suspension system and the wheels : The triangle arm acts as a bridge connecting the suspension system and the wheels to ensure that the wheels maintain the correct positioning and Angle during the driving process, thus ensuring the handling and comfort of the vehicle .
balance support : the triangle arm plays a balance support role on the uneven road surface, absorbs shock by swinging, reduces the jolt and vibration of the body, and keeps the vehicle running smoothly .
maintain vehicle stability : the triangle arm helps the body to maintain stability during driving, reduces the turbulence and vibration up and down, and makes the driving route more accurate .
transmission force and guidance : the triangle arm plays a vital role in the automobile suspension system, which transfers all kinds of forces acting on the wheels to the body, and ensures that the wheels move along a certain track .
The working principle of the triangle arm : the triangle arm is actually a universal joint, which can be associated with the action even when the relative position of the driver and the slave changes. For example, the shock absorber being compressed while steering causes the A-arm to swing up .
Maintenance and replacement suggestion : When the triangle arm is deformed, the ball head is damaged, the rubber sleeve is aging, etc., it needs to be repaired or replaced. Regular inspection and maintenance can ensure the normal operation of the triangle arm and extend its service life .
The automobile triangle arm , also known as the swing arm, is an important part of the automobile chassis suspension system. Its main function is to balance the support to ensure that the vehicle can cope with uneven roads smoothly during the driving process. When the tires encounter bumps or undulations, the triangle arm absorbs the impact by swinging, thus protecting the safety of the vehicle and passengers .
Structure and working principle
The triangle arm is connected to the axle head mounted on the tire through the ball head. When the vehicle is driving on the uneven road surface, the tire will swing up and down. This action is completed by the swing of the triangle arm. The triangular arm is actually A universal joint, which can still be associated with action when the relative position of the driver and the follower changes, such as when the vibration absorber is compressed to make the A-arm swing .
Fault identification and maintenance
The failure of the triangle arm will affect the driving stability and safety of the vehicle. Common failures include:
vehicle jitter during braking : When the rubber bushing on the triangle arm is damaged, the vibration generated during braking will enter the carriage and cause jitter. The solution is to replace the damaged bushing .
excessive deflection of the ball head : excessive aftershocks and abnormal sounds occur in the chassis of the vehicle when it passes through the speed bump, usually due to serious wear of the triangle arm ball head. The solution is to replace the worn ball head .
triangle arm deformation : Check whether the triangle arm has collision marks, if necessary, professional maintenance or replacement .
Maintenance suggestion
When the triangle arm is deformed, the ball head is damaged or the rubber sleeve is aging, it is recommended to go to the professional repair shop for inspection and repair in time. In addition, regular inspection and maintenance of the status of the triangle arm can extend its service life and ensure driving safety .
