Walking device

Abstract

The invention relates to a walking device, and belongs to a walking chassis of a vehicle. The walking device adopts the technical proposal that the walking device comprises a vehicle frame (1) and four basic wheel sets driven independently with same structures, each basic wheel set comprises an axle housing (2), a driving shaft (3), belt wheels (4) and (4'), connecting rods (5) and (5'), wheel shafts (6) and (6'), a belt wheel (8) and a wheel (7), a belt wheel (8') and a wheel (7'), belts (9) and (9'), and a hydraulic cylinder (10). The four basic wheel sets driven independently form a full-wheel full-time drive walking system when driving simultaneously, an included angle alpha between the connecting rods (5) and (5') is adjusted through the expansion and contraction of a cylinder rod ofthe hydraulic cylinder (10), so as to adjust ground clearance of the walking device, the connecting rods (5) and (5') follow up around the driving shaft (3) to achieve profile modeling of tyres (7) and (7') to the ground, and the walking system is steered through changing the drive rotating speed of the basic wheel sets at two sides.

Description

technical field [0001] The invention relates to a running device, which belongs to a vehicle running chassis and can improve the vehicle's passability and adaptability to complex ground. technical background [0002] Most of the wheel installation methods used on vehicles at present are that the wheels are directly connected and installed with the transmission shaft, so that the chassis height of the vehicle is basically fixed or can only be slightly adjusted through the suspension. If the chassis is high, the stability of the vehicle body is relatively poor when driving, especially when driving at a high speed or turning, it is easy to cause rollover and cause traffic accidents.

AI Technical Summary

Problems solved by technology

If the chassis is high, the stability of the body is relatively poor when driving, especially when driving at a high speed or turning, it is easy to cause rollover, and traffic accidents occur.

The chassis of the vehicle is too low. When the road conditions are relatively poor, such as muddy, uneven roads, the chassis of the vehicle is more likely to collide or rub against the ground, and the vehicle's passability is poor.

[0003] Most of the chassis of large-scale trucks are supported by multiple axles, and the chassis is made of rigid materials. When passing through uneven roads, some wheels may hang in the air, which reduces the load capacity and passability of the vehicle.
