What is the function of the triangle arm of the car?
The function of the triangle arm is to balance the support.
The car is driving on the uneven road surface, the tire will swing up and down, that is, the swing of the triangle arm is completed, the tire is installed on the shaft head, and the shaft head is connected by the ball head and the triangle arm. The triangular arm is actually A universal joint, which can still be associated with action when the relative position of the active and the slave changes, such as when the vibration absorber is compressed to make the A-arm swing up.
The triangular arm is connected with the subframe through the front connection point articulated sleeve set on the subframe, and the force and impact of the wheels are transmitted to the body through the front connection point articulated sleeve of the subframe, the front connection point articulated sleeve of the subframe is likely to crack, that is, if there is a "broken shaft" accident, there is a high probability of the position of the articulation sleeve of the front connection point of the subframe.
