Abstract

The invention discloses a vacuumized adsorption bottom surface type automobile emergency braking and turnover and drifting preventing device. The device is characterized in that the device comprises a vacuum body, a main vacuum pump and a lifting connection device, wherein the vacuum body is fixed to a chassis of an automobile through the vertically-arranged lifting connection device, and a main negative pressure port of the vacuum body communicates with a suction port of the main vacuum pump through a pipeline. The vacuumized adsorption bottom surface type automobile emergency braking and turnover and drifting preventing device utilizes the negative air pressure principle, in order to brake the automobile, the vacuum body descends quickly to make contact with the ground and forms a closed space with the ground, meanwhile, the closed space is vacuumized, pressure on the ground is formed, and the braking purpose is achieved through frictional force between the device and the ground; and meanwhile, downward adsorption force is additionally generated, so that the automobile is effectively prevented from turning over or drifting.

Description

technical field [0001] The invention relates to an external braking device for automobiles, in particular to a vacuum suction bottom surface type automobile emergency braking and anti-rollover and drifting device. Background technique [0002] Existing automobile braking mainly relies on the friction between the tire and the ground to obtain the braking resistance and realize it. With the development of automobile technology, the speed is getting faster and faster, and the frictional resistance between the tire and the ground is required to be as small as possible, while the braking distance will become longer and longer, and it is difficult to balance the two. In order to increase the friction force during braking, the tire surface texture design has been optimized to the extreme. Therefore, it is no longer feasible to increase the braking resistance by increasing the ground roughness and tire friction coefficient. Moreover, the existing braking technology relying on tire ...
