Device for controlling compressed air distribution and use for vehicle through combination valve

Abstract

The invention discloses a device for controlling compressed air distribution and use for a vehicle through a combination valve. The device comprises a compressed air inlet, a switch valve stop position, a duty ratio valve air inlet and a pressure sensor. An output end of the compressed air inlet is connected with the input end of the switch valve stop position; and the output end of the switch valve stop position is connected with the input end of a first air outlet and the input end of a second air outlet, the output end of the first air outlet and the output end of the second air outlet areconnected with the input end of the duty ratio valve air inlet, and the output end of the duty ratio valve air inlet is connected with the input end of the pressure sensor. According to the device forcontrolling compressed air distribution and use for the vehicle through the combination valve, a complex mechanical structure is not needed, a simple two-position three-way switch valve, a duty ratiovalve and a one-way valve structure are adopted, a purpose that a unique compressed air source meets requirements of two air using units with different time domains and different pressures is achieved, and mutual interference is avoided. The device is suitable for the vehicle.

Description

technical field [0001] The invention relates to the technical field of the automobile industry, in particular to a device for controlling the distribution and use of compressed air for vehicles through a combination valve. Background technique [0002] With the popularization of vehicles, the automobile brake system is also gradually paid attention to. The automobile brake system adopts two independent pressure adjustment mechanisms and controllers according to the gas demand of the two gas units with different pressure and flow characteristics to realize pressure , Real-time and on-demand control of the flow rate, but the existing devices for the distribution of compressed air for vehicle manufacturing still have certain defects, such as: [0003] The existing device used for compressed air distribution for vehicle manufacturing needs to be matched with a controller unit, a pressure regulation structure and a pressure sensor for the air supply control of each air unit. The ...
