Abstract

The invention discloses a rail traffic vehicle auxiliary brake control system which comprises a filter arranged on a pipeline and communicated with a main air pipe, a check valve communicated with thefilter, and a plurality of connecting ports. The main air pipe is communicated with the auxiliary brake control system. The check valve is communicated with a brake air storage cylinder. The auxiliary brake control system further comprises an overflow valve communicated with the filter, a depressurizing valve communicated with the overflow valve. a third plug communicated with the check valve, athrottling valve communicated with the third plug, a controllable valve communicated with the throttling valve, and a second plug communicated with the controllable valve. The depressurizing valve iscommunicated with an air spring system. The overflow valve is communicated with an air spring air storage cylinder. The second plug is connected with a parking brake unit. The auxiliary brake controlsystem integrates the air filtering and supplying functions of the brake air storage cylinder and the air supply and vehicle parking brake control functions of the air spring system; corresponding installing supports and installing pipelines can be reduced, the linear loss of the pipelines is reduced, and the response speed of the system is increased.

Description

technical field [0001] The invention relates to the field of rail transit vehicles, in particular to an auxiliary braking control system for rail transit vehicles. Background technique [0002] In the domestic urban rail transit braking field, EP2002 electro-pneumatic brakes occupy most of the market share, and as the provider of the installation bracket and auxiliary braking control function of EP2002 electro-pneumatic brakes, the auxiliary braking control unit is in The proportion of models equipped with EP2002 electro-pneumatic brakes is also higher than 50%. Therefore, the auxiliary braking control unit is widely used in the domestic urban rail transit industry. The auxiliary braking control system is an integrated device. All vehicles are installed. The auxiliary braking control unit in the prior art is unreasonably designed, and multiple control devices are scattered on the air circuit board, which requires a large area of ​​the air circuit board and is extremely inco...
