The invention provides an automatic cushion wheel device for preventing a motor vehicle from sliding on a slope accidentally, a mounting frame is fixedly erected at the position above the rear side of a corresponding wheel of a chassis, a cushion block retracting and releasing mechanism, a cushion block locking mechanism and a cushion block pushing mechanism are erected in the mounting frame, a trapezoidal cushion block with an arc notch is hung below the mounting frame, and the trapezoidal cushion block is connected with the mounting frame. When the cushion block is used, a driver can control and finish the process of automatically padding the wheel and withdrawing the cushion block by one person in a cab. According to the automatic cushion wheel device, the cushion block retracting and releasing mechanism is driven by the gear with the one-way clutch mechanism, so that the impact resistance is high, and the operation is stable; the cushion block locking mechanism is provided with a locking assembly and an unlocking assembly, so that the cushion block can be prevented from accidentally loosening and falling off when the vehicle bumps; the U-shaped fork frame is arranged on the cushion block pushing mechanism, so that the operation of pushing and withdrawing the cushion block can be accurate in place, and as the swing arm and the cushion block adopt a specific connection mode, the cushion block cannot move backwards along with the vehicle, and the success of wheel cushioning can be ensured.
本发明提供了一种防止机动车意外溜坡的自动垫轮装置,其安装框架固定架设在车底盘对应车轮后侧上方的位置,安装框架内架设有垫块收放机构、垫块锁置机构和垫块推送机构,安装框架的下方吊挂有一个带有圆弧缺口的梯形垫块,使用时司机在驾驶室内一个人即可控制完成垫块自动垫轮和收回垫块的过程。本自动垫轮装置在垫块收放机构使用带单向离合机构的齿轮进行传动,抗冲击性强,运行稳定;在垫块锁置机构设置了锁止组件和解锁组件,可防止在车辆颠簸时垫块意外松脱掉落;在垫块推送机构设置了U形叉架,使得推送垫块和收回垫块的操纵能够准确到位,而且由于摆臂与垫块采用特定的连接方式,垫块不会跟随车辆后移,可确保垫轮成功。
