Wheel-legged mechanism of motor vehicle, wheel-legged motor vehicle and wheel-legged motor vehicle group

Abstract

The invention relates to a wheel-legged mechanism of a motor vehicle, the wheel-legged motor vehicle and a wheel-legged motor vehicle set, and belongs to the field of motor vehicles; the wheel-legged mechanism comprises thighs, thigh driving units, shanks, shank driving assemblies and wheels; each thigh is connected with a hollow shaft, the hollow shafts are rotatably connected to a vehicle frame, and a containing cavity is formed in each thigh; the thigh driving units are connected with the hollow shafts and drive the hollow shafts to drive the thighs to swing; the shanks are hinged to the thighs; each shank driving assembly comprises a transmission unit arranged in the corresponding containing cavity and a shank driving unit arranged on the vehicle frame, the transmission units drives the shanks to rotate, and the shank driving units are in transmission connection with the transmission units through rotating shafts; the wheels are rotationally arranged at one ends of the shanks; the posture of the wheel-legged type mechanism is adjusted through rigid mechanical transmission, the wheel-legged type mechanism can be used under multiple working conditions, the design structure is simple, control is easy, the problem that control lags behind due to the fact that a sensing technology and a control system are adopted traditionally is solved, and the control accuracy is improved.

Description

technical field [0001] The invention relates to the field of wheel-leg structures of motor vehicles, in particular to a wheel-leg mechanism of a motor vehicle, a wheel-leg type motor vehicle and a wheel-leg type motor vehicle unit. Background technique [0002] The wheel-leg structure of motor vehicles has the advantages of high passability of leg movements and high mobility of wheel movements. Therefore, it is widely used in mountainous vehicles, engineering emergency vehicles and military fields, and can deal with various complex It has good road condition adaptability, especially the ability to pass obstacles. When the existing motor vehicle is driving under different road conditions, it is necessary to adjust the posture of the wheel-leg structure on it to meet the needs of different road conditions. In unstructured terrain, it is necessary to climb over obstacles with leg movements. However, the existing adjustment of the posture of the wheel-leg structure of the moto...

Problems solved by technology

[0003] The purpose of this application is to solve the problem that the posture adjustment of the wheel-leg mechanism of the existing motor vehicle is generally controlled by hydraulic means when the vehicle is overcoming obstacles. The problem of inaccurate control, meanwhile, increases the weight of the motor vehicle to a certain extent and reduces the maneuverability of the motor vehicle. To solve the above problems, it is specifically:
