In order to reduce vehicle body vibration caused when moving wheels meet obstacles and improve riding comfort, the following technology is adopted: a wheel shaft does certain arc motion around a frame fixing shaft, when a vehicle advances and meets the obstacles, the wheels move backwards (relative to the vehicle body), the impact force of the obstacles during advancing is reduced, meanwhile, the wheels are lifted upwards, and the wheels are driven to move forwards. And the vertically upward shaking force of the obstacle to the wheels is reduced. Therefore, the obstacle crossing capability of the vehicle is improved. A horizontally-installed spring is adopted to control the wheel shaft to do certain arc motion around the frame fixing shaft, and the spring generates component force in the horizontal direction so as to balance backward resistance borne by the wheels. The invention has the following beneficial effects: when the vehicle encounters an obstacle at first, the wheels move backwards and upwards under the action of impact force, so that the vibration of the obstacle to the vehicle body is reduced in a large-radian manner. Namely, vibration force in the vertical direction caused by obstacles on the vehicle body and the human body is reduced. And meanwhile, the impact force on the wheels is reduced, and the whole structure of the vehicle is protected to a certain degree.
为减小运动车轮遇障碍物引起的车身震动,提高乘坐舒适感,本发明采用了如下技术:将车轮轴绕车架固定轴作一定的圆弧运动,当车辆前进遇障碍物时,车轮将向后移动(相对于车身),减小前进时障碍物的冲击力,同时车轮向上抬起,减小障碍物对车轮竖直向上的震动力。从而提高车辆对障碍物的跨越能力。控制车轮轴绕车架固定轴作一定的圆弧运动的是采用了水平安装的弹簧,弹簧将产生水平方向的分力,以平衡车轮受向后的阻力。本发明有益效果是:当车辆初遇障碍物时,在冲击力作用下,车轮将作向后和向上运动,从而大弧度减少障碍物对车身的震动。也就是减小车身和人体受障碍物引起的垂直方向的震动力。同时也对车轮本身减小了冲击力,对车的整体结构有一定的保护作用。
