Abstract

The invention discloses a foot joint structure of a wheel type walking type vehicle steering drive axle. An upper mechanical leg is fixedly connected with a motor assembly; the motor assembly comprises two gear motors which are coaxial in output shaft and oppositely arranged, and the two gear motors serve as power sources and provide torque for wheel steering and foot joint movement; a transmission mechanism assembly can convert the single-direction output of the motor into two different-direction outputs, namely the rotation of wheels around a main pin and the rotation of the foot joint around the axis of the motor; a foot joint rotation locking mechanism is used for locking the rotation movement of the foot joint and positioning the position of the foot joint in a wheel steering mode, and a wheel steering locking mechanism is used for locking the steering of the wheels and positioning the position of the wheels in a foot joint rotation mode. The foot joint structure has two transmission routes, well decomposes the rotation motion of the foot joint around the wheel main pin and the rotation motion around a motor rotating shaft, switches the working modes by means of the two locking mechanisms, is reliable and effective, and has good application potential.

Description

technical field [0001] The invention belongs to the technical field of wheeled walking vehicles, in particular to a foot joint structure of a steering drive axle of a wheeled walking vehicle. Background technique [0002] Walking vehicles have strong adaptability to complex terrain by virtue of their structural characteristics. Most of the existing walking vehicles are driven by crawlers, the structure is relatively complicated, and it is difficult to realize the high-speed driving of the vehicle. A feasible method is to use wheels instead of crawlers to reduce the weight of the vehicle and improve the power and economy of the vehicle while ensuring the adaptability to complex terrain. Unlike the tracked steering method, wheeled vehicles have to consider the wear of rubber tires, and cannot use the steering method of differential speed between wheels. However, the foot joint structure of general walking vehicles only realizes the rotational motion of the foot joint, which ...
