Characteristics of the single-point suspension series:

1. The structure between the single-point suspension and the trailer is simple to install, has low manufacturing costs, and is easy to maintain.

2. When the left and right wheels bounce, they are interconnected, resulting in small changes in tire angle and thus minimal tire wear.

3. It is not easy to change the angle of the wheels when the vehicle height is lowered, so as to maintain a consistent feeling of control.

4. It occupies less space and can reduce the height of the vehicle floor.
