The invention discloses a motor-driven four-wheel walking and steering mechanism. The motor-driven four-wheel walking and steering mechanism comprises a driving wheel, a third driven wheel, a first driven wheel, a second driven wheel and the like, and a first transmission device is synchronously connected to the driving wheel; the first transmission device is synchronously connected to the first driven wheel, and a one-way transmission mechanism is arranged between the first driven wheel and the second driven wheel; or a one-way transmission mechanism is arranged between the first transmissiondevice and the first driven wheel, and a rotating shaft is synchronously connected between the first driven wheel and the second driven wheel. When the motor-driven four-wheel walking and steering mechanism normally advances, the driving wheel rotates forwards, and other three wheels are driven to rotate through the first transmission device, the one-way transmission mechanism and the second transmission device; and when the driving wheel rotates reversely to perform reversing action, the one-way transmission mechanism can interrupt force transmission, so that the second driven wheel and thethird driven wheel lose the driving force of autorotation, and finally the steering action of the motor-driven four-wheel walking and steering mechanism is completed. The motor-driven four-wheel walking and steering mechanism in reasonable in structure layout, simple in structure, and stable in operation is stable, and can complete wheel driving and equipment steering through a single motor.
本发明公开了一个电机驱动四轮行走和转向机构,包括驱动轮、第三从动轮、第一从动轮、第二从动轮等结构,第一传动装置同步连于驱动轮;第一传动装置同步连于第一从动轮,第一从动轮与第二从动轮之间设有单向传动机构;或者第一传动装置与第一从动轮之间设有单向传动机构,且第一从动轮与第二从动轮之间同步连有转轴。设备在正常前进时,驱动轮正转,通过第一传动装置、单向传动机构、第二传动装置带动其它三个轮子转动;当驱动轮反转作倒车动作时,单向传动机构会中断力的传递,从而使第二从动轮和第三从动轮失去自转的驱动力,最终完成设备的转向动作。本发明结构布局合理、结构简单、运行平稳且仅需单电机就能完成轮子的驱动和设备转向。
