Abstract

The invention discloses a brake sucker device shrunk under the chassis of an automobile and a braking method thereof. The braking distance of the car braking system is too long during emergency braking. The pressure sensor of the present invention is fixed on the upper surface of the foot brake; the high-pressure pump is used to supply air to the air intake hole of the outer cylinder of the retractable rod; the piston of the retractable rod is fixed to the inner end of the inner rod; The inner end face is fixed; the ball hinge support 1 of the ball hinge 1 is connected to the bottom surface of the automobile chassis through a connecting piece; the ball head 1 of the ball hinge 1 is fixed to the outer cylinder, the inner rod is fixed to the ball joint 2 of the ball hinge 2, and the ball joint 2 of the ball hinge 2 is fixed. The second ball hinge support is fixed with the suction cup; the inner cavity of the suction cup is fixed with an ultrasonic detector; When the vehicle runs at high speed and brakes suddenly, the suction cup pops up to the ground along with the contraction rod, and an adsorption force is generated between the vacuum pump and the ground, which greatly shortens the braking distance of the vehicle.

Description

technical field [0001] The invention belongs to the technical field of automobile braking, and in particular relates to a brake sucker device shrunk under an automobile chassis and a braking method thereof. Background technique [0002] The current automobile braking system will inevitably produce a certain braking distance during emergency braking, which seriously threatens the life safety of drivers, passengers and passers-by. According to the relationship between the speed of the car and the braking distance, when a car brakes on a dry asphalt road at a speed of 80 km / h, the resulting braking distance is about 14-40 meters. The reaction time of the driver and the braking time of the braking system can be increased to between 50-60 meters, and the existence of the braking distance has caused most of the car accidents. [0003] If the car can act on the road surface by means of external force when braking, the braking distance of the car can be greatly reduced, and the occ...
