Independent suspension system of trailer

Abstract

The invention relates to the technical field of trailer suspensions, in particular to a trailer independent suspension system which comprises two wheel assemblies, two brake assemblies and a chassis bearing frame and further comprises a suspension connector, a cantilever connector and two damping assemblies. The brake assembly is installed at the axis position of the wheel assembly and fixedly connected with the cantilever combination piece, one side of the cantilever combination piece is movably connected with a front cross beam of the suspension combination piece, the other side of the cantilever combination piece is movably connected with a longitudinal beam of the suspension combination piece through the damping assembly, and the suspension combination piece is fixedly connected with the chassis bearing frame. The independent suspension system of the trailer is simple in structure and convenient to assemble, the impact force of the ground on wheels and a frame can be attenuated, vibration of the frame is reduced, the overall braking performance of the trailer is improved, the smooth stability of the trailer in the running process and the safety of goods are guaranteed, and the service life of parts of the trailer is prolonged; the occupied trailer chassis space is small, and the economic cost is saved.

Description

technical field [0001] The invention relates to the technical field of trailer suspension, in particular to a trailer independent suspension system. Background technique [0002] Trailer refers to a wheeled vehicle that relies on the traction of other vehicles and has no power drive itself. It cooperates with the traction vehicle to form a complete and effective transportation and mobile platform. It is widely used in road freight, container transportation market, equipment material transportation and equipment loading. In other aspects, the transportation capacity can be doubled without increasing the tractor and driver. When the vehicle is running on uneven ground, the wheels drive the frame to vibrate vertically, thus affecting the stability of the vehicle. Suspension system is a general term for all force-transmitting connection devices between the frame and the axle or wheels. It is generally composed of elastic components, guide devices and shock absorbers, which can ...

AI Technical Summary

Problems solved by technology

However, the structure of the air suspension system is complicated, and the processing is cumbersome. The airbag assembly adopted has a large structural size, a variety of parts, high assembly accuracy requirements, low roll angle stiffness, troublesome maintenance, and takes up a lot of space on the chassis of the trailer.
