Automobile tire safety device and working method thereof

Abstract

The invention relates to an automobile tire safety device and a working method thereof. The device comprises an inner ring (1), an intermediate ring (2) and an outer ring (3), wherein the inner ring (1) is fixedly connected with the outer circle of an automobile tire hub (14), the intermediate ring (2) is arranged between the inner ring (1) and the outer ring (3), the outer ring (3) and the intermediate ring (2) form a free-slip contact, the intermediate ring (2) and the inner ring (1) form a free-slip contact, the cross section of the intermediate ring (2) is a concave-convex shape, the surface shape of the outer circle of the inner ring (1) is matched with the surface concave-convex shape of the inner circle of the intermediate ring (2), and the surface shape of the inner circle of the outer ring (3) is matched with the surface concave-convex shape of the outer circle of the intermediate ring (2); and the inner ring (1), the intermediate ring (3) and the outer ring (3) are encased in the an automobile outer tire. The device can decompose the instant impact stress, transfer the friction force by speed difference, prevent the direction from being out of control and keep the original running speed and direction of wheels invariant as much as possible.

Description

technical field [0001] The invention relates to an automobile tire safety device and its working method for avoiding accidents caused by vehicle tire blowout during driving. The automobile tire safety device is a safety protection device installed on the vehicle hub and suitable for vacuum tire structure. It belongs to the technical field of mechanical design. Background technique [0002] The driving of the vehicle relies on the engine to generate power, and the power is finally evenly transmitted to the wheels through the transmission shaft. The outer surface of the wheel tire realizes the walking of the vehicle under the action of gravity and friction. When the vehicle suddenly blows out while driving at a high speed, the tire loses air pressure, and under the action of gravity, the contact surface between the outer surface of the tire and the ground suddenly increases, and the friction force also increases at the same time as the contact surface increases. And the impac...

Problems solved by technology

However, in the implementation process of the above technical solutions, it is found that there are still some defects, which cannot achieve the expected goals.

For example, the cross-sectional shape of the safety device is not reasonable enough, and the sudden force is too concentrated, which cannot effectively disperse and transfer the high impact force; The high frictional resistance generated cannot be effectively released and transferred, and cannot reduce or avoid accidents after a tire blowout; the outer surface of the outer ring rubs against the inner surface of the tire, and the high temperature generated by the friction between the inner surface of the outer ring and the outer surface of the inner ring, The tires and safety devices are quickly destroyed and cannot play their due role; and the reliability of the connection device of the outer ring is not enough, etc.
