Safe and energy-saving wheel with variable grounding area

Abstract

The invention belongs to the technical field of tires and relates to a safe and energy-saving wheel with a variable grounding area. The wheel comprises an inner rim, an outer rim, a tire assembly anda sliding block assembly; the inner rim is arranged in the outer rim, the tire assembly is arranged outside the outer rim, and the tire assembly comprises an inflatable tire and an expansion tire skin; one end of the sliding block assembly is connected with the inner rim, the other end of the sliding block assembly penetrates through the outer side of the outer rim, is connected with the expansiontire skin and can drive the expansion tire skin to move up and down under the functions of the inner rim and the outer rim, a limiting mechanism is arranged between the sliding block assembly and theouter rim, a plurality of curved-surface lifting plates are evenly distributed on the outer circumference of the inner rim, and a plurality of idler wheels are evenly distributed on both sides of theouter circumference of the inner rim. The wheel achieves the purposes of reducing the braking distance and improving the safety performance or saving energy or fuel on different road surfaces or in different driving states by changing the grounding area of the tire, and has the advantages of being simple in structure, convenient to use, reasonable in design, practical, efficient and the like.

Description

technical field [0001] The invention belongs to the technical field of tires, and in particular relates to a safe and energy-saving wheel with a variable ground contact area. Background technique [0002] With the technological development of automobiles and the increasing pursuit of vehicle performance and economy by users, most manufacturers match them with wider low-section ratio tires to meet consumers' high requirements for braking performance, but the tire width has a great impact on long-distance The fuel consumption of a walking car has a greater impact, and the degree of wear is greater than that of narrow tires. When the car is running at high speed, standing waves will appear on the wheels, and in severe cases, it will explode, which will easily cause the car to lose control. Therefore, in order to comply with this requirement, an invention of a safe and reliable tire that can realize energy saving without affecting the braking performance has been proposed at pre...
