Embodiment 1

[0032] A commercial vehicle air pressure brake-by-wire master cylinder of the present invention is installed in the engine compartment in front of the driver through the flange hole on the valve body, the adjustment fork is connected with the brake pedal in the driver compartment, and the air intake hole on the valve body is connected with the brake pedal in the driver compartment. The pipeline connection of the brake air storage tank is connected with the air outlet of the variable pressure chamber on the valve body and the brake pipeline leading to the brake. The harness connector on the valve body is used to connect the internal solenoid valve assembly circuit and the external embedded system controller. The pressure sensor installed on the valve body is connected with the embedded system controller by wires. The circuit pins of the micro switch are connected with the embedded system controller by wires. The embedded system controller is installed in the cockpit and connec...

Abstract

The invention belongs to the technical field of automobile brake systems, and particularly relates to an air pressure line control brake master cylinder for a commercial vehicle. The master cylinder comprises a one-cavity pump body component. The one-cavity pump body component comprises a one-cavity cylinder body, a dust cover, an ejector rod base, a rubber spring, a feedback rubber pressing plate, a limiting ring check ring, a microswitch, a driving piston, a driving return spring, a first piston component, a first piston spring, an electromagnetic valve device, an air guide screw, a series piston, a pressure sensor, a push rod and an adjusting fork. A two-cavity pump body component comprises a two-cavity cylinder body, a second piston part, a second piston spring, an exhaust seat and an exhaust seat check ring; and an embedded system controller is arranged outside the brake master cylinder. The air pressure line control brake master cylinder is reasonable in structure, has a brake-by-wire function, and can meet the technical requirements of intelligent network connection commercial vehicles of the level L2 or above; and meanwhile, a driver operation function is achieved, and the braking mode and the braking pedal feeling are consistent with those of a common commercial vehicle.

Description

technical field [0001] The invention relates to the technical field of automobile brake systems, in particular to a commercial vehicle air pressure brake-by-wire master cylinder. Background technique [0002] At this stage, the rapid development of my country's intelligent networked vehicle technology has put forward higher requirements for the wire-controlled and intelligent braking system of commercial vehicles. In the existing commercial vehicle brake-by-wire system technology, there are deficiencies in the requirements for both the driver's operation function and the brake-by-wire function of the intelligent networked vehicle. Comfort, stability, consistency requirements. [0003] The present invention is a commercial vehicle air pressure brake by wire master cylinder. Its working principle is to install a solenoid valve device at the high pressure chamber, variable pressure chamber and exhaust channel inside the commercial vehicle air pressure brake master cylinder. A...
