AIR DISTRIBUTOR OF BRAKE OF ROLLING STOCK AND METHOD OF PARAMETERS SETTING Russian patent published in 2015 - IPC B60T15/18 B60T17/22 B60T13/26 

FIELD: machine building.

SUBSTANCE: air distributor contains in main line part the intermediate accelerating chamber with spring-loaded check valve and pusher. The pusher is located in tail of the movable partition and acts on the additional charging spring-loaded valve with tail installed in the channel of the additional charging. The tail acts on the spring-loaded brake valve, which spring rests on the sleeve with throttle atmosphere hole, connected with seat body of the brake valve by means of the thread connection. The tail of the additional charging valve ahs symmetrical cuts along the cylinder generatrix creating symmetrical grooves in the valve body for air passage upon completely opened brake valve. The valve spring has work part of the power characteristic that is always below its complete power characteristic. Method of the parameters setting of the air distributor contains testing of the air distributor at the group test rig with measurements of the set parameters, in particular of the brake wave speed. Then for the device setting the element characteristics are selected with maximum impact on the tested parameter, for example, for spring of the additional charging valve - spring force, number of turns, wire quality, force at specified compression value until achievement of the required device parameter.

EFFECT: increased operation efficiency of brake equipment.
