Abstract

The invention discloses a retractable type non-inflatable wheel allowing a ground contact area of a tire tread to be changed. The non-inflatable wheel comprises a main wheel body, auxiliary wheel bodies, wheel retracting mechanisms and a wheel spoke, wherein the main wheel body and the auxiliary wheel bodies are coaxially arranged, the main wheel body adopts an overall non-inflatable elastic wheel, each auxiliary wheel body is a non-inflatable wheel equally divided in the circumferential direction, the main wheel body is connected with a wheel axle through the wheel spoke, hinge sliding guide grooves are circumferentially formed in the wheel spoke and extend in the radius direction of the wheel spoke from a center hole of the wheel spoke, the number of the hinge sliding guide grooves is equal to the sum of the segmentation number of the auxiliary wheel bodies, one end of each wheel retracting mechanism is connected in a corresponding hinge sliding guide groove, and the other end of each wheel retracting mechanism is connected with the auxiliary wheels. The ground contact area of the non-inflatable wheel can be changed according to road surface conditions, hidden tire burst risks are avoided, the safety is good, and the retractable type non-inflatable wheel is suitable for being used under various driving conditions.

Description

technical field [0001] The invention relates to a retractable non-pneumatic wheel with a variable tread contact area, which belongs to the technical field of non-pneumatic tires. Background technique [0002] In order to improve the passability of wheeled vehicles on soft roads, gravel roads and other off-road surfaces, oval tires, arch tires, sand tires, high off-road special tires, desert bionic tires and other specifications of wide-section, small aspect ratio Pneumatic tires are widely used. For the above-mentioned off-road tires of all inflation types, they all have a common shortcoming. Due to the harsh driving environment, they are easily pierced by sharp objects and cause deflation or bursting, thereby making the vehicle lose its maneuverability. In addition, by increasing the width of the tire section, the rolling resistance of the wheel will increase and the fuel consumption will increase. [0003] In addition, for tires of all inflation types mentioned above, th...
