| description | A train brake cylinder pressure control system, comprising: a load pressure feedback apparatus (10) for generating a corresponding load pressure according to a load status of a train; a train brake reservoir (20) for providing a brake reservoir pressure; a dispensing valve (30) for adjusting a train brake pipe pressure and the brake reservoir pressure to output indirect brake pre-control pressures; a bi-directional valve (40) for selecting and outputting the greater one of the two pre-control pressures; and a relay valve (50) for adjusting the plurality of input pressures and outputting a final brake cylinder pressure. By implementing the graduated brake and the graduated release of a train by means of a dispensing valve (30) and using the input amount of the dispensing valve as a parameter that affects the overall adjustment effect of the relay valve (50), trains having a same speed and different loads stop, using a final brake cylinder pressure, at a same brake distance with a same deceleration, so that the probability of an excessive brake force in an unloaded state is reduced. Also provided is a rail train provided with the train brake cylinder pressure control system. |
