Problems solved by technology

[0005] (2) Multiple solenoid valves are used for distributed arrangement to achieve multiple functions, and the pipeline arrangement is complicated and reduces the reliability of the system
[0006] (3) When the solenoid valve is powered off, the general switch solenoid valve cannot maintain the current state, which will cause the vehicle to brake suddenly, posing a safety hazard
[0007] (4) When the solenoid valve leaks, it may cause the pressure of the parking brake chamber to accumulate and cause the car to slide, which poses a safety hazard and reduces the reliability of the system

Abstract

The invention relates to the technical field of commercial vehicle brake, and discloses a commercial vehicle air pressure electronic parking brake module. The commercial vehicle air pressure electronic parking brake module comprises a controller 50, a shell 56, a relay valve 4, a two-position two-way electromagnetic valve 1, a two-position two-way pneumatic control valve 2, a two-position three-way electromagnetic valve 3, a first driving electromagnetic coil 90 and a second driving electromagnetic coil 91. The whole module adopts integrated design. Compared with a traditional parking brake system, the module has the advantages that connection between a pneumatic pipeline and an electrical circuit is reduced, the module has the advantages of being high in integration degree, small in installation space and high in reliability, meanwhile, follow-up overhaul is facilitated through integrated installation, and the maintenance cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of commercial vehicle braking, in particular to a commercial vehicle pneumatic electronic parking brake module. Background technique [0002] With the development of automotive electronics technology, the application of electronic parking in passenger cars has become increasingly mature, but the application of electronic parking in commercial vehicles is still in its infancy, especially the pneumatic electronic parking applied to the pneumatic braking system system (EPB). Compared with the traditional parking system, the electronic parking system has the advantages of convenient installation and simple operation, and with appropriate control technology, it can also realize hill start assistance, dynamic braking, and anti-slip that cannot be achieved by traditional manual parking brakes. Slope and other functions have broad application prospects. [0003] At present, the actuators of the pneumatic electroni...
