Abstract

The invention discloses a composite telescopic-diameter walking wheel to solve the technical problems that the adaptation capacity of wheel type transportation to complex ground is relatively poor and the trafficability characteristic is relatively weak caused by the prior art. The composite telescopic-diameter walking wheel comprises large-diameter parts, intermediate-diameter parts, small-diameter parts, a reducing disc and a fixed disc. By rotating the reducing disc, the large-diameter parts are pushed through five groups of crank slider mechanisms to achieve the telescopic diameter. The composite telescopic-diameter walking wheel provided by the invention can be directly arranged on the existing vehicle like a common tire, and is matched with a track, and the track can be switched by changing the size of the diameter, so that the vehicle has an efficient running speed and good ground adaptability.

Description

technical field [0001] The invention relates to a wheel, in particular to a wheel whose diameter can be changed. Background technique [0002] Transportation machinery is widely used in various fields, and its working environment may be a structured environment, or a complex, unknown, and changeable unstructured environment in the natural environment. Therefore, the obstacle surmounting ability is an important index to test the road passability of mobile robots. [0003] The moving mechanisms of the transportation machinery that have appeared mainly include wheel type, crawler type and leg type. Among them, the wheel type has the highest efficiency, but the diameter of the wheel cannot be changed, making it relatively poor in adaptability and low in passability; while the leg type Basically, it is made by imitating the shape of the lower limbs of humans or animals. It has the strongest adaptability but the lowest efficiency, and the difficulty of motion control is relativel...
