Automobile braking system adopting electric execution mechanism

Abstract

The invention discloses an automobile braking system adopting an electric execution mechanism, and belongs to the technical field of automobile braking. The system comprises an execution motor, two fixed gears and two rotating nuts, wherein the two fixed gears and the two rotating nuts are symmetrically arranged on two sides of a brake disc; the two rotating nuts are separately and fixedly connected with two planar bearings; the two planar bearings are respectively separately and fixedly connected with two spring bases; springs are arranged in the two spring bases; the two springs are respectively and separately connected with two push rods; the two push rods are respectively and separately connected with two friction sheets; the two friction sheets are respectively and symmetrically arranged on the two sides of the brake disc; and the braking of the two friction sheets are realized while the braking disc is clamped at the same time. According to the automobile braking system disclosed by the invention, the total quality of the automobile is reduced, the maintenance is simple, braking force directly acts upon the brake disc, and the braking speed is higher, and the braking response time is obviously shorter than conventional automobile braking time, so that the braking efficiency is effectively improved, the braking distanced is shortened, and the security of vehicles is improved.

Description

technical field [0001] The invention relates to an automobile braking system, in particular to an automobile braking system using an electric actuator, and belongs to the technical field of automobile braking. Background technique [0002] At present, most automobile brakes use hydraulic brake wheel cylinders as brake actuation devices, and oil pipes are used to transmit pressure oil. The pressure loss is relatively large, and hydraulic transmission uses hydraulic oil as the working medium, which is inevitable between the relative moving surfaces. There must be leakage, and the oil is not absolutely incompressible, so it is difficult to achieve constant ratio transmission. Contents of the invention [0003] The main purpose of the present invention is to provide an automobile brake system using an electric actuator to solve the problem of large pressure loss and the use of hydraulic oil as the brake actuator in the prior art. The medium is easy to leak and it is difficult...
