Double-tire structure wheel with adjustable grounding area

Abstract

The invention belongs to the technical field of tires, and relates to a double-tire structure wheel with an adjustable grounding area, which comprises a main wheel solid tire 1, a main rim 2, an auxiliary transmission shaft 3, a small locking bolt 4, a limiting block 5, an auxiliary rim 6, a large locking bolt 7, an auxiliary wheel outer tire 8, a one-way bearing 9, an auxiliary wheel inflatable inner tire 10, an air adjusting valve 11 and a main transmission shaft 12. A double-tire structure is adopted; under different road surfaces or different driving states, the outer diameter of the auxiliary wheel outer tire is changed by adjusting the air pressure of the auxiliary wheel outer tire, the grounding area of the tire is thus changed, the purpose of reducing the brake distance to improvethe safety performance is thus realized, the advantages of being simple in structure, convenient to use, reasonable in design, practical, efficient and the like are achieved, the main tire and the auxiliary tire can be connected with the hub and the motor, and therefore kinetic energy recovery and hybrid acceleration are achieved.

Description

technical field [0001] The invention belongs to the field of wheels, in particular to a twin-tire structure wheel with adjustable 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. Contents of the invention [0003] In order to solve the above problems, the present invention provides a twin-tire structure wheel with adjustable ground contact area. The twin-tire structure is used to change th...
