Abstract

The invention relates to an EBS trailer valve which comprises an air pressure sensor, a proportional electromagnetic valve, a valve body, a first piston and a second piston. A valve and a return spring are installed in the second piston, the first piston and the second piston are connected, and the air pressure sensor and the proportional electromagnetic valve are arranged on the valve body and connected with an ECU. The valve is provided with a first valve port and a second valve port, a third piston is arranged on the valve, a conical spring is disposed outside the third piston, and a fourth piston is arranged on the upper side of the third piston. An iron core is arranged on the inner side of the proportional electromagnetic valve, an upper valve is arranged on the lower side of the iron core, an exhaust port is formed in the lower side of the upper valve, an air inlet valve is arranged below the exhaust port, an ejector rod is arranged below the air inlet valve and connected with a throttling piston, a spring is arranged on the outer side of the throttling piston, and a throttling block is connected to the throttling piston. A cavity connected with the valve body through a pipeline is formed in the valve body. The EBS trailer valve is good in braking effect, low in cost and long in service life.

Description

technical field [0001] The invention belongs to the technical field of vehicle equipment, and in particular relates to an EBS trailer valve. Background technique [0002] The trailer valve, also known as the trailer brake valve, is used to cut off the air supply pipeline of the trailer according to the driver's control, and at the same time connect the air supply pipeline to the atmosphere for braking. The trailer brake valve usually has three vents: one through the air reservoir, one through the main vehicle brake valve, and one through the disconnect switch. When the car brakes, the compressed air from the main car brake valve enters the trailer brake valve, closes the air intake channel of the air storage tank (wet air storage tank), cuts off the air source, and makes the trailer brake valve go to the air pipe of the separation switch. The compressed air is quickly discharged. At this time, the distribution valve on the trailer will cause the compressed air in the air s...
