Main functions of thrust lever
Prevent bridge displacement:
Straight thrust rod: Limits the front and rear displacement of the middle and rear axle.
V-shaped thrust rod: In addition to preventing front and back displacement, it can also prevent left and right displacement. When the car turns, the middle and rear axle may shift left and right due to mechanical action, which will cause friction between the plate spring and the tire, and even lead to premature tire wear or puncture in serious cases. The unique structural design of V-type thrust rod enables it to deal with this problem effectively.
Stabilizing the body:
Transverse thrust rod: Made of spring steel, shaped like a "U" shape, placed across the front wall and the rear wall of the car. The middle part of the rod body is hinged with the frame through a sleeve, and the two ends are fixed on the left and right suspension. When the body rolls, the runout of the suspension on both sides is inconsistent, and the lateral thrust rod is twisted, which produces the elastic resistance to the roll and plays the role of lateral stability.
Transmission force and moment:
The thrust rod connects the frame with the axle, which solves the problem that the leaf spring cannot transmit traction force, braking force and corresponding reaction torque, so that the axle and the frame can move simultaneously.
