Did you get the right suspension for the semitrailer?

The double wishbone suspension usually adopts unequal wishbone (short upper and long lower), which can automatically change the camber angle when the wheel moves up and down, reduce the change of track width and reduce the tire wear. It can also adapt to the road, with large tire grounding area, good tire adhesion and enhanced friction. But because of the structure, there is an upper rocker arm, so it takes up a large space.

The trailing arm suspension system is a suspension system specially designed for the rear wheels. This kind of suspension is called semi independent suspension. Its advantages are that the space between the left and right wheels is large, the camber angle of the body does not change, and the shock absorber does not produce bending stress, so it has small friction and good riding performance. When braking, in addition to the heavy front, the rear wheel suspended by the trailing arm will also sink to balance the body. However, it can not provide accurate geometric control. However, if properly adjusted, the best effect can be achieved with the least cost and space. Therefore, this form of rear suspension is widely used in today's cars.

There are so many semi-trailer suspensions, we need to choose the semi-trailer suspension suitable for our own use according to our own needs, in order to more effectively improve the stability of the semi-trailer! https://www.chinaaxle.cn
