Automobile auxiliary braking device

Abstract

The invention discloses an automobile auxiliary braking device. The automobile auxiliary braking device comprises a brake disc, a high pressure pump, an oil storage tank, a controller and a heat radiator; the brake disc is arranged on a transmission shaft of an automobile and comprises a shell, a first brake blade, a second brake blade, a third brake blade and a fourth brake blade; the first brake blade, the second brake blade, the third brake blade and the fourth brake blade are vertically arranged on the transmission shaft of the automobile; the shell is shaped like a circular disc and seal the first brake blade, the second brake blade, the third brake blade and the fourth brake blade inside; a first oil inlet, a second oil inlet, a third oil inlet and a fourth oil inlet are uniformly formed in the shell in the radial direction of the transmission shaft of the automobile; an oil outlet is formed in the bottom of the shell; the first oil inlet, the second oil inlet, the third oil inlet and the fourth oil inlet of the shell are all connected with an oil outlet of the high pressure pump; the oil outlet of the shell is connected with the oil storage tank; one end of the heat radiator is connected with the oil storage tank; and the other end of the heat radiator is connected with an oil inlet of the high pressure pump. During working, the controller obtains braking information from a central control module of the automobile and controls the high pressure pump to work during the braking of the automobile. The automobile auxiliary braking device has the advantages that the structure is simple, the cost is low, the braking is soft, the wear of a friction disc of the automobile is reduced and a certain anti-lock function is also achieved.

Description

technical field [0001] The invention relates to the field of automobile braking, in particular to an auxiliary braking device for automobiles. Background technique [0002] At present, the ABS anti-lock braking system is generally used on middle and high-end cars, which greatly improves the braking of the car. But the cost of ABS is high, and it is rarely used in low-speed cars, especially trucks. Therefore, trucks often have tires locked, and long tire scratches can often be seen on the road. In this way, the friction plates of trucks wear heavily, and the braking effect is not good, which often leads to tail flicking and rollover. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an auxiliary braking device for automobiles, which not only has a better braking function, but also can To a certain extent, prevent the wheel from locking up. [0004] The present invention adopts the following technical solutions fo...
