The invention provides an automobile high-speed running tire burst risk avoiding device. A supporting rack and a jacking rack which can move up and down and have the lower ends exposed out of a shell are inserted into the shell; a supporting wheel is arranged at the lower end of the supporting rack, and a wheel shaft of the supporting wheel is connected with the lower end of the jacking rack through a crank connecting rod reciprocating mechanism. A gear shaft and a driving device are erected in the shell, a gear is arranged on the gear shaft, meshed with the supporting rack and capable of driving the supporting rack to move up and down, and the gear shaft is further connected with a forward rotation locking mechanism and a reverse rotation locking mechanism which are used for limiting forward rotation and reverse rotation of the gear shaft. A displacement locking claw capable of limiting the jacking rack to only move downwards but not move upwards is further erected in the shell; the risk avoiding device is further provided with an external tire burst signal touch connection device. According to the risk avoiding device, the supporting wheel can be bounced down to touch the ground and then quickly and automatically jacked to a proper height when the tire of the wheel is punctured, so that a vehicle quickly recovers to be balanced, and traffic accidents caused by out-of-control of the direction of the vehicle due to tire burst are avoided or reduced.
本发明提供了一种汽车高速行驶爆胎避险器,其壳体内插装有可上下移动且下端头露出在壳体之外的支撑齿条和顶升齿条;支撑齿条的下端头设有支撑轮,支撑轮的轮轴通过曲柄连杆往复运动机构与顶升齿条的下端头相连接;壳体内架设有齿轮轴并设有驱动装置,齿轮轴上设有齿轮与支撑齿条啮合并可带动其上下移动,齿轮轴上还连接有用于限制齿轮轴正转和反转的正转止锁机构和反转止锁机构;壳体内还架设有可限制顶升齿条只能下移不能上移的移位止锁爪;本避险器还配有外置的爆胎信号触通装置。本避险器在车轮发生爆胎时能够使支撑轮弹下着地随即迅速自动顶升至适当高度,使车辆快速恢复平衡,避免或减少因爆胎导致汽车方向失控造成的交通事故。
