Example Embodiment

[0017] The following describes the present invention in further detail with reference to the accompanying drawings and specific embodiments, without limiting the scope of implementation of the present invention.

[0018] Such as Figure 1 to Figure 7 As shown, the inflation-free and variable contact area tire described in this embodiment includes a tire body 1. The tire body 1 includes a tread 11 that is in contact with the ground, and both sides of the tread 11 face the tire body 1. The sidewall 12 formed by the extension of the central axis of the tire, the inner surface 13 opposite to the tread 11, and the inner groove formed by the inner surface 13 and the two sidewalls 12, the tread 11 is provided with an interval for slip resistance and increased friction The tread pattern of the tire further includes a pressure-regulating airbag 2 arranged in the inner groove, and an elastic supporting member 3 is arranged between the adjusting airbag and the inner surface 13 of the tire b...

Abstract

The invention discloses a non-pneumatic tire with a variable contact area. The non-pneumatic tire comprises a pressure regulating air bag, wherein the pressure regulating air bag is arranged in an inner groove; an elastic supporting part is arranged between the pressure regulating air bag and the inner surface of a tire body; the elastic supporting part comprises two side rings arranged side by side, a plurality of elastic pieces connected between the two side rings and distributed in a circumferential array, and a plurality of elastic driving parts connected between the two side rings and distributed in a circumferential array; the side rings are fixed to tire walls of the tire; and each of the elastic driving parts comprises a cylinder body, a first piston, a first piston rod, a second piston, a second piston rod and a tee joint. The non-pneumatic tire with the variable contact area is provided with the pressure regulating air bag and the elastic supporting part to support the tire body, thereby allowing the tire body to keep the shape of the tire without the need for inflation, and effectively avoiding the problems of tire punctures, blowouts and other faults. In addition, the pressure regulating air bag cooperates with the elastic supporting part to change the contact area between the tire and the ground so as to affect the rolling resistance of the tire.

Description

technical field [0001] The invention relates to a tire without inflation and variable contact area. Background technique [0002] Existing tires are basically pneumatic tires, and problems such as tire puncture or blowout often occur, and the contact area between the tire and the ground cannot be adjusted and changed basically. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages mentioned above, and provide a tire without inflation and variable contact area. [0004] To achieve the above object, the specific scheme of the present invention is as follows: [0005] An air-free tire with a variable contact area, comprising a tire body, the tire body includes a tread in contact with the ground, sidewalls formed by extending the two sides of the tread towards the central axis of the tire body, and a tire opposite to the tread The inner surface and the inner groove formed by the inner surface and the two tire walls. The tread...
