Abstract

The present invention relates to a wire-controlled chassis system for a four-wheel independent steering unmanned vehicle, belonging to the technical field of unmanned driving. Each of the suspension systems corresponds to a steering system. The suspension system includes a linear bearing mechanism, a rotary damping mechanism and a spring buffer mechanism. The two ends of the rotary damping mechanism are respectively fixed on the body frame and the steering system. The ends are respectively elastically connected to the upper end of the linear bearing mechanism and the top of the steering system. The present invention can constrain the movement of the steering system through the linear bearing mechanism, so that the steering system only moves in the up and down direction, so as to realize the anti-rotation effect on the wheel during the shock absorption process, and the present invention simultaneously uses the buffer spring and the rotary damping mechanism Work to effectively absorb the energy effect generated by vehicle vibration.

Description

Technical field[0001]The present invention relates to the field of drivatic technology, and in particular, a line-control chassis system that is four-wheeled independently switched to unmanned vehicles.Background technique[0002]With the rapid development of unmanned driving technology, the research of unmanned line-controlled chassis system technology program is more and more, but common line-control chassis system technology is mainly based on the chassis of traditional vehicles, resulting in modification Unmanned vehicle application field is limited.[0003]A four-wheeled independent drive independent steering chassis bias shaft mechanism is disclosed in the utility model of CN201820455792.5, which belongs to the field of vehicle engineering. In order to solve the fixed beam intensity of the existing four-wheeled independent drive independent steering chassis is not enough to pass the gap small, the utility model includes: a bias arm steering system, a damping support structure, and...
