Abstract

The invention discloses an electric control brake system used for a trailer. The electric control brake system comprises an electric control unit (1), a brake signal detection unit (2), a brake execution mechanism (3) and a power source (4). The signal input end of the electric control unit (1) is connected with the signal output end of the brake signal detection unit (2), the signal output end ofthe electric control unit (1) is connected with the signal input end of the brake execution mechanism (3), and the power source (4) is connected with the power input ends of the electric control unit(1) and the brake execution mechanism (3). The electric control brake system is sensitive in braking and stable in brake direction, brake sideslips are unlikely to happen, no braking is conducted inthe trailer backing process, and the braking characteristic is adjustable.

Description

technical field [0001] The invention belongs to the technical field of automobile braking systems, in particular to an electronically controlled braking system for trailers with sensitive braking, stable braking direction, low braking sideslip, no braking when reversing, and adjustable braking characteristics. system. Background technique [0002] In order to cooperate with tractors with different types of braking systems, the trailer braking system at home and abroad generally adopts the inertial braking system. [0003] Inertial braking system is divided into mechanical inertial braking system and hydraulic inertial braking system. [0004] The structure of the mechanical inertial braking system is simple, and the braking can generate corresponding braking force with the change of braking deceleration of the tractor. Chinese invention patent application "trailer" (application number: 200810054115.3, publication date: 2010.09.08) discloses a mechanical inertial braking sy...
