Deformable wheel device

Abstract

The invention discloses a deformable wheel device, in particular to a deformable wheel which is used for a light vehicle and can adapt to different pavements. The deformable wheel comprises a deformable rim and a driving shaft, wherein an inner gear ring is arranged on the inner surface of the deformable rim; a driving wheel and a guide wheel are meshed on the inner gear ring; the driving wheel and the guide wheel are symmetrically arranged at two sides of the vertical line of the center of a circle of the deformable rim; a spacing wheel A and a spacing wheel B are respectively installed at the opposite parts of the driving wheel and the guide wheel on the outer surface of the deformable rim; the centers of the spacing wheel A and the driving wheel are positioned on the same line; and thecenters of the spacing wheel B and the guide wheel are positioned on the same line. When a vehicle is loaded, the deformable wheel of the invention deforms into a similar ellipse from a circle, thereby changing the ground contact area, reducing the unit pressure and improving the trafficability of the vehicle; and the greater the load is, the larger the deformation is, and the larger the ground contact area is. When the vehicle runs on a hard pavement, an adjusting device can be used for keeping the wheel similar to a circle, thereby improving the running speed.

Description

technical field [0001] The invention belongs to a vehicle running device, in particular to a deformable wheel of a light vehicle that can adapt to different road surfaces. Background technique [0002] At present, the most researched and most widely used walking mechanisms are wheel-type, crawler-type, and leg-foot-type walking mechanisms. [0003] The wheel-type walking mechanism has the advantages of fast walking speed and flexible steering. It is adopted by most vehicles. Almost all modern cars use a wheel-type structure. impact, and ensure good adhesion and friction between the wheel and the road surface, but due to the small contact area between the wheel and the ground, when the car is running on a soft road, it is prone to slipping and sinking, and the adaptability and passability are greatly improved. Reduced, even if some cars are equipped with a tire pressure adjustment system, the contact area between the wheel and the ground is changed by adjusting the air press...
