Abstract

The invention discloses an air-pressure type service braking system having a hill-starting assisting function. The system comprises an air storage tank (2), a foot valve (4) and an air brake chamber (8) which are in series connection through an air channel, a relay valve (6) is further in series connection between the foot valve (4) and the air brake chamber (8), the system further comprises a pneumatic control solenoid valve (5), one end of the pneumatic control solenoid valve (5) is connected with the relay valve (6), and the other end of the pneumatic control solenoid valve (5) is connected with an outlet air channel of the foot valve (4). The service braking system is simple in structure and short in time of responding to hill-starting assisting action, and no influence is produced on an original braking line.

Description

technical field [0001] The invention belongs to the technical field of assisting devices for starting on a hill, in particular to a pneumatic service braking system with a ramp-starting assisting function, which has a simple structure, short action response time and no influence on the original brake pipeline. Background technique [0002] Traditional vehicles require the driver to have skilled accelerator, clutch and brake coordination technology during the hill start process to ensure that the vehicle does not slip backwards. This requires a high level of driver's control skills, and improper operation is prone to danger. The hill start assist system is based on the electronic control method to realize the automatic or auxiliary control of the car's hill start. [0003] The existing service brake system with auxiliary hill start function, such as Chinese patent CN201320138667.9 (application number: 201320138667.9, publication date: 2013.08.28), this patent adds a two-posit...
