Problems solved by technology

Due to the disadvantages of the traditional hydraulic braking system, such as easy leakage of the hydraulic circuit, slow braking response speed, poor pedal performance, difficult assembly and maintenance, and difficult module integration, people have developed a new generation of automotive braking systems, namely brake-by-wire System (Brake By Wire)
However, the existing brake-by-wire brakes lack the brake clearance adjustment function, and the axial and radial dimensions are relatively large, making installation difficult

Abstract

The invention discloses an automobile brake controlled by a wire, which comprises a brake disc, wherein a friction plate is arranged on each of the two sides of the brake disc; the friction plates are fixedly connected with a piston which can axially move along a brake caliper body and is connected with a trapezoid nut; the trapezoid nut can axially move along an inner hole of the piston and is in fit connection with a trapezoid threaded end of a screw rod; a driving nut is movably arranged on a ball screw section of the screw rod and is fixedly connected with a worm gear; the worm gear is engaged with a worm which is fixedly connected with an output end of a driving motor of the brake to covert the rotation motion of the driving motor of the brake into linear motion; and the driving motor of the brake is perpendicular to a brake caliper of the brake. The automobile brake controlled by the wire has automatic regulation and parking braking functions, can improve reinforcement effect, is high in braking performance, simple in structure, convenient to mount, easy to maintain and less in energy consumption, and can ensure the constancy of brake response speed of a vehicle so as to further ensure the braking performance.

Description

technical field [0001] The invention relates to a brake, in particular to an automobile wire-controlled brake. Background technique [0002] "Safety, energy saving, and environmental protection" are the three themes of the future development of automobiles. As an important part of automobiles, the braking system directly affects the safety of automobiles. With the development of modern science and technology, at the same time, consumers' requirements for automobile safety performance are increasing day by day, and automobile brakes have also been continuously developed. [0003] The current braking system is based on the traditional hydraulic braking system, implanted ABS (anti-lock braking system), TCS (tracking control system), ESP (electronic body stabilization device) and so on. Due to the disadvantages of the traditional hydraulic braking system, such as easy leakage of the hydraulic circuit, slow braking response speed, poor pedal performance, difficult assembly and ...
