Unmanned vehicle chassis structure with telescopic rocker suspension

Abstract

The invention belongs to the technical field of unmanned vehicle chassis, and in particular relates to an unmanned vehicle chassis structure with a telescopic rocker suspension. The chassis structure of the unmanned vehicle includes: a car body and four suspension systems; the four suspension systems are arranged at the front, rear, left and right corners of the car body; the four suspension systems Both include: electric wheel assembly, wheel-side independent steering assembly, telescopic rocker arm assembly, rocker arm drive and elastic damping system assembly; through the large-angle swing and large-stroke expansion of the telescopic rocker arm, not only the vehicle body can be adjusted Lifting, pitching and rolling can also greatly improve the passability of trench and obstacle crossing, and increase the stability of climbing and the ability to pass through slopes; combined with the independent steering of the wheel, it can also achieve centripetal steering and meet a reasonable turning radius need.

Description

technical field [0001] The invention belongs to the technical field of unmanned vehicle chassis, and in particular relates to an unmanned vehicle chassis structure with a telescopic rocker suspension. Background technique [0002] In recent years, unmanned vehicles have higher and higher requirements for stable posture and passability. Many unmanned vehicle chassis have adopted rocker suspensions that occupy less space and have a simple structure to improve passability. , At the same time, the oil and gas spring scheme is adopted to realize the adjustment of the vehicle posture. However, the length of the single trailing arm in the traditional rocker arm suspension is fixed, and the rocker arm alone has certain limitations in the ability to cross trenches and obstacles. The structure of the oil-gas spring is too complicated. The sealing performance requirements are very high, resulting in difficult processing, high manufacturing costs and difficult use and maintenance. Co...
