Self-force-increasing type electronic-mechanic brake for automobile

Abstract

The invention discloses a self-force-increasing type electronic-mechanic brake for an automobile. An upper friction plate and a lower friction plate are arranged at the two sides of a brake disc. The upper friction plate is fixedly mounted on a brake caliper body. The brake caliper body is mounted on a brake caliper bracket through guiding rods and can move axially on the guiding rods. A dust cover is arranged between the brake caliper body and each guiding rod. A first motor is fixed to a lower wedge block through first screws. The first motor is connected with a first threaded rod through a first coupling. The first threaded rod is in transmission connection with a push rod through a thread. In the braking process, the first motor drives the first threaded rod to rotate, the first threaded rod pushes the push rod to move in the horizontal direction, and furthermore, the push rod pushes an upper wedge block to move in the horizontal direction and the vertical direction; normal brake clearances are eliminated; and the lower friction plate is in contact with the brake disc, and braking is achieved. The self-force-increasing type electronic-mechanic brake for the automobile has the self-force-increasing function; the input torque of each motor can be greatly reduced; and meanwhile, the self-force-increasing type electronic-mechanic brake has the function that the clearance can be adjusted automatically, and wear of the friction plates is compensated.

Description

technical field [0001] The invention relates to an automobile braking system, in particular to an automobile electromechanical brake. Background technique [0002] With the rapid development of automotive electronic technology, automotive braking technology is gradually developing towards electromechanical systems, and more secure, efficient, energy-saving, and environmentally friendly automotive electromechanical braking technologies have emerged.
