Abstract

The invention discloses an active trailer braking system. The active trailer braking system comprises a 15-core electric connector (1), a connecting member (2), an electric control unit (3), a motor hydraulic system (4) and a storage battery (5); a signal input end of the electric control unit (3) is connected with signal output ends of the connecting member (2) and the 15-core electric connector(1); a signal output end of the electric control unit (3) is connected with a signal input end of the motor hydraulic system (4); a power supply output end of the 15-core electric connector (1) is connected with power supply input ends of the storage battery (5) and the motor hydraulic system (4); and a power supply output end of the storage battery (5) is connected with power supply input ends ofthe electric control unit (3) and the motor hydraulic system (4). The active trailer braking system has the advantages of sensitive braking, no braking during backing and adjustable braking characteristic.

Description

technical field [0001] The invention belongs to the technical field of automobile braking systems, in particular to an active trailer braking system with sensitive braking, no braking when reversing and adjustable braking characteristics. Background technique [0002] The trailer itself has no power drive, and the traction is provided by the tractor. The braking system of a trailer is different from that of a towing vehicle. At present, the trailer braking system at home and abroad usually 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 inerti...
