Antiskid assembly tire for motor vehicle

Abstract

The invention discloses an antiskid assembly tire for a motor vehicle. The tire is characterized in that: a synchronous locking device comprises a transmission shaft, a cover plate, a back plate of which the center is provided with a bearing, and stay cords of which one ends are provided with hooks; the edge of the back plate is provided with wire outlets corresponding to outside tire sidewall rubber; the cover plate is fixedly connected with the back plate; one end of the transmission shaft is assembled with the bearing, and the other end of the transmission shaft is an adjusting end which is exposed out of a central through hole of the cover plate and is fixedly connected with a gear; the gear is matched with a limit pin arranged on the cover plate; the transmission shaft is provided with clamping grooves corresponding to the outside tire sidewall rubber; the fixed ends of the stay cords are fixed in the clamping grooves, and the hook ends of the stay cords pass through the wire outlets; and damping interlayers are arranged in interfaces of the outside tire sidewall rubber. The synchronous locking device of the assembly tire is easy and convenient to adjust, large in locking force, uniform in tightness in all directions and convenient to operate; and in the running process of the motor vehicle, vibration caused by different elasticity of tread rubber on metals and rubber at interface joints is eliminated, and the safety is high.

Description

technical field [0001] The invention relates to tire antiskid equipment for motor vehicles, in particular to an antiskid equipment tire for motor vehicles. Background technique [0002] When a motor vehicle is driving on a mountainous area, desert, grassland, snow or icy road and the tires slip on the ground, the emergency anti-skid method is usually to wrap the iron chain on the tire and tie it tightly to the wheel hub. This emergency method is due to the Due to the separation between the steel ring of the wheel hub and the axle center connector, the distance between adjacent iron chains after winding is too large, and it is very difficult to crawl on the bad road surface, slipping and walking, and the anti-skid effect is not ideal. [0003] In order to solve this problem, I have previously applied for the "anti-skid equipment tire for motor vehicles" with the publication number CN201989576U. It is four petals, of which the tread rubber joint is detachable, and the other t...

AI Technical Summary

Problems solved by technology

[0004] The equipment tire with the above structure, because of the metal connecting rod at the connection end of the interface, is different from the tread rubber elasticity of the equipment tire, which will cause the vehicle body to vibrate during driving; the tightness adjustment device is a screw type, which can only Adjustment of a single screw can not be well adjusted synchronously to complete the synchronous locking. There is a possibility that the locking will deviate from the center of the tire. Improper adjustment will directly affect the anti-skid effect, and the operation is inconvenient
