Independent suspension system of unmanned vehicle

Abstract

The invention discloses an independent suspension system of an unmanned vehicle. The independent suspension system comprises a chassis, a motor assembly, a suspension assembly and a tire assembly, the motor assembly comprises a driving motor, a motor shaft and a universal joint, the driving motor is mounted in the chassis, and one end of the universal joint is connected with the motor shaft; the suspension assembly comprises an upper rocker arm, a lower rocker arm and a rocker arm support, one ends of the upper rocker arm and the lower rocker arm are hinged to the chassis side by side, the other ends are hinged to the rocker arm support, the upper rocker arm and the lower rocker arm are parallel, and a mounting opening is formed in the middle of the rocker arm support. The tire assembly is rotationally arranged in the mounting opening and connected with the universal joint. The stress of the tire assembly can be more uniformly transmitted to the rocker arm bracket, the upper rocker arm and the lower rocker arm and then better dispersed into the chassis, so that the stress performance of the suspension assembly is improved, and the use safety of the suspension assembly is further improved.

Description

technical field [0001] The invention relates to the technical field of unmanned vehicles, in particular to an independent suspension system for unmanned vehicles. Background technique [0002] The unmanned vehicle suspension system is the general term for all force transmission connection devices between the unmanned vehicle chassis and the wheels. Its function is to transmit the force and moment acting between the chassis and the wheels, and to buffer the impact force transmitted to the chassis from uneven roads. , and attenuate the vibration caused by it to ensure the smooth driving of unmanned vehicles. Many existing unmanned vehicles use independent suspension systems to realize the omnidirectional steering function of unmanned vehicles and greatly improve the mobility and maneuverability. [0003] At present, most of the suspension systems of unmanned vehicles are constantly innovating and improving the suspensions in order to consider their own stability, shock absorp...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the suspension systems of unmanned vehicles are constantly innovating and improving the suspensions in order to consider their own stability, shock absorption and flexibility, but often ignore the installation and connection between the suspension system and the chassis. During the process, due to the uneven force on the suspension system, it is impossible to better distribute the force on the suspension system to the chassis, resulting in the suspension system being prone to damage or abnormal phenomena during use, which makes the use of the suspension system more secure.
