Technical Field
The utility model belongs to vehicle accessories, concretely relates to trailer hangs assembly.
Background
Trailers generally comprise an underframe, a running gear arranged below the underframe and a cargo bed arranged above the underframe. The chassis is connected with the running gear through a suspension system. The suspension system is one of the core parts of the vehicle, and not only influences the bearing capacity of the whole vehicle, but also greatly influences the running smoothness and the braking performance of the whole vehicle. Due to the special use of the semitrailer, the suspension system of the semitrailer often has some characteristics which need special attention in use, such as rated load bearing, self-weight of suspension, matching with an axle, matching with a plate spring, length and angle of a pull rod, and the like. Once the assembly is not proper, phenomena such as tyre eccentric wear, tyre gnawing and the like can be caused. The service life of the tire and the running stability are seriously influenced.
