Moving device

Abstract

The invention relates to a moving device which comprises a power source and an input shaft driven by the power source and transversely arranged along the Y axis; two sides of the input shaft are eachcoaxially connected with an output wheel; two sides of each output wheel are each provided with at least one guide wheel I with the axial direction being the Y direction, and duplex synchronous wheelswith the axial direction being the Z direction are arranged at the positions above a pair of adjacent wheels. Transmission among the duplex synchronous wheels, the guide wheels I and the output wheels is achieved through a synchronous belt capable of being twisted and turning; two sides of the duplex synchronous wheels achieve synchronous belt transmission through at least one guide wheel II withthe axial direction in the X direction and a walking belt wheel with the axial direction in the Y direction. The walking belt wheel and the wheels are coaxially connected or in coaxial transmission.A traditional steering trapezoidal mechanism is replaced by the moving device, the weight is reduced, meanwhile, limitation of a steering trapezoid is avoided, and the four wheels can independently complete steering; belt transmission replaces traditional transmission parts, and the weight can be reduced.

[0002] The existing mobile devices that can realize all-wheel drive and all-wheel steering generally have relatively complicated structural design in terms of power and transmission of wheel drive / steering. Generally, more than two power sources are required for driving. If only one power source is used , the transmission structure will be very complicated, the design and manufacture are difficult, and the space is often insufficient, and the cost is high;

[0003] Existing high-precision mobile devices, such as mobile devices that can realize all-wheel drive and all-wheel steering, have deficiencies in the design of body balance, resulting in poor adaptability of the mobile device to the ground, which is not conducive to Safety and stability of mobile device walking;

[0004] In addition, the existing mobile devices need to generate sliding friction with the ground when the wheels turn. Generally, due to structural design limitations, it is impossible to achieve pure rolling steering. This is a mobile device that requires high positional accuracy. It is very unfavorable; at the same time, for some special areas, the ground roughness is extremely high, and the wear resistance of the wheels is very high, resulting in high cost of the wheels and shortening the life of the mobile device
