What is the rod connecting the wheels called?

[DeElaina]

The rod connecting the wheels is called the car suspension. Here is some relevant information about car suspension: 1. Definition: The suspension system is the general term for all the force-transmitting connecting devices between the car's frame and the axle or wheels. Its function is to transmit the forces and torques acting between the wheels and the frame, buffer the impact force from uneven road surfaces to the frame or body, and dampen the resulting vibrations to ensure smooth driving. 2. Non-independent suspension system: The structural feature of a non-independent suspension system is that both wheels are connected by an integral axle, and the wheels together with the axle are suspended under the frame or body through an elastic suspension system.
