Mechanical automobile tire burst support device

Abstract

The invention discloses a mechanical automobile tire burst support device. The support device comprises telescopic components, a casing and a tempered glass ring, wherein the telescopic components are uniformly distributed in a circumferential direction of the casing; the tempered glass ring is arranged on the outer sides of the telescopic components in a sleeving manner; each telescopic component comprises a hub section, a support claw, a spring and a support bar; guide grooves and clamp ports are formed in the casing; one end of each support bar is connected with the middle part of each hub section, and the other end is inserted into the guide grooves of the casing; and each support claw comprises a pair of claws and a spring, the support claw is mounted in the middle of the part where each support bar is inserted into each guide groove, and each spring is arranged on the periphery of the part, extruding out of each guide groove, of each support bar. According to the mechanical automobile tire burst support device, the support for weight of an automobile with a burst tire during emergency is achieved through the telescopic components, automobile tire burst support devices with different specifications are configured by the automobile according to different automobile models, loads and tire models, so that the problems that an RSC (roll stability control) anti-explosion tire is poor in comfort, troublesome in dismounting and the like are solved; and further, the automobile tire burst support device is simple in structure, low in price and obvious in emergency effect, and can be widely applied to tires of vehicle s such as a sedan, a coach, a touring bus and the like.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a mechanical automobile tire burst support device. Background technique [0002] In recent years, the tire blowout accidents of vehicles have increased suddenly. According to statistics, the traffic accident blowout on the expressway accounts for more than 70%. Car accidents caused by frequent tire blowouts have aroused people's vigilance and confusion. [0003] At present, the commonly used run-flat tires are BMW RSC run-flat tires. RSC run-flat tires have thickened rubber sidewalls. Even if the air pressure is lost, the sidewalls can support the weight of the vehicle without causing serious deformation. It will seriously affect the driving of the vehicle. However, the hard side wall has its advantages and disadvantages. The most obvious change brought about by the hard side wall is that the riding comfort is reduced; secondly, because the side wall is too hard, it is quite trouble...
