Probe vehicle wheel with variable diameter elastically capable of automatic extension

Abstract

A probe vehicle wheel with variable diameter elastically capable of automatic extension relates to a probe car wheel. The invention solves the problem that the existing lunar vehicle has bad obstacle ability when meeting high barriers and traveling on loose and soft lunar slope as the wheel of the existing lunar vehicle is rigid wheel and the devices inside the wheel are impacted due to collisionbetween the wheel and hard object. A driving flange is connected with the output end of a speed reducer in a driving device, the driving flange is hinged with a plurality of support bars, the other end of the support bar is hinged with a slide bar, one end of the slide bar is fixedly connected with the inside wall of a flange sheet, the other end of the slide bar is sleeved with a spring and is inserted in a corresponding sliding chute together with the spring, the slide bar can radially slide along the sliding chute, one end of the spring is fixedly connected with the slide bar, the other end of the spring is fixedly connected with the bottom of the sliding chute, a limited block is installed inside the sliding chute and positioned outside the spring, and a plurality of tooth sheets are uniformly distributed on the flange and are fixedly connected with the flange. In the invention, the wheel diameter can be adjusted automatically according to topographic condition, thereby improving wheel traveling ability and reducing the impact of wheel for the devices inside.

Description

Exploring car elastic and automatically retractable variable diameter wheels technical field The invention relates to a detection vehicle wheel. Background technique Exploration vehicles used on planetary surfaces or other harsh environments require strong terrain adaptability and flexible steering capabilities. The rover wheel is one of the most critical components of the rover's mobile system. The configuration of the wheels has a critical impact on the driving ability of the lunar exploration vehicle and the ability to adapt to the lunar surface terrain. The wheels of the rover must be able to effectively reduce the ground pressure, that is, reduce the amount of sag of the wheels; and create necessary constraints on the flow of dust particles, resulting in greater traction. At present, the structure of the wheels of the exploration vehicle mostly adopts a rigid cylindrical wheel structure. When this kind of wheel walks on the surface of the moon on rocky obstacles an...
