Passenger car braking pipeline system for cold region

Abstract

The invention relates to a passenger car braking pipeline system for a cold region. The passenger car braking pipeline system for the cold region comprises an air compressor, a dehumidification air cylinder, a condenser, a drying device and a four-circuit valve, wherein the air compressor, the dehumidification air cylinder, the condenser, the drying device and the four-circuit valve are connected in sequence through pipelines. The type of the four-circuit valve is WABCO9347140100, and an outlet of the drying device is connected with an opening 1 of the four-circuit valve. An opening 21, an opening 22, an opening 23 and an opening 24 of the four-circuit valve are connected with a rear braking air cylinder in a rear braking pipeline system, a front braking air cylinder in a front braking pipeline system, a hand braking air cylinder in a hand braking pipeline system, and an auxiliary air cylinder in an auxiliary air system respectively; the air compressor is a double-cylinder water-cooling type air compressor, and an electric heater is arranged on the drying device.

Description

[0001] technical field [0002] The invention relates to a passenger car brake pipeline system, in particular to a passenger car brake pipeline system used in cold regions. Background technique [0003] As far as passenger cars are concerned, the braking system used is a double-circuit air braking system, that is to say, the braking force is mainly provided by the high-pressure gas from the engine air pump. Then the temperature of the gas pumped out by the engine pump generally reaches about 100°C. The gas at this temperature will contain a large amount of water vapor. When cooled to a certain temperature, the water vapor will liquefy into water. When the vehicle is running in a cold area, The water in the pipeline will freeze, which will affect the function of each valve and the smoothness of the air circuit, endangering the safety of the whole vehicle. At the same time, the exposed brake pipeline in low temperature environment also has potential safety hazards. Contents ...
