Unmanned vehicle chassis structure with telescopic rocker arm suspension

Abstract

The invention belongs to the technical field of unmanned vehicle chassis, and particularly relates to an unmanned vehicle chassis structure with a telescopic rocker arm suspension. The unmanned vehicle chassis structure comprises a vehicle body and four suspension systems. The four suspension systems are arranged at the front corner, the rear corner, the left corner and the right corner of the vehicle body. Each suspension system comprises an electric wheel assembly, a wheel edge independent steering assembly, a telescopic rocker arm assembly and a rocker arm driving and elastic damping systemassembly. Through large-angle swinging and large-stroke stretching and retracting of telescopic rocker arms, lifting, pitching and side tilting of the vehicle body can be adjusted, the ability of passing trenches and crossing obstacles can be greatly improved, and the climbing stability and the side-tilting slope passing ability are improved; and in combination with wheel edge independent steering, centripetal steering can be achieved, and reasonable steering radius requirements can be met.

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...
