RAIL VEHICLE BRAKING EQUIPMENT SYSTEM Russian patent published in 2024 - IPC B61H13/24 B60T11/04 B60T11/20 

FIELD: rail vehicles.

SUBSTANCE: invention relates to railway transport, particularly, to braking equipment. Braking equipment system contains actuators located on the rail vehicle bogie, including brake cylinders with built-in rod output regulators, connected by connecting hoses with the brake cylinders air duct, made with possibility to provide independent transmission of braking forces to brake lever transmissions serviced by them with simultaneous action on bogie wheel pairs brake shoes, wherein in each brake cylinder first and second pistons are sequentially installed, each of which contains a rod, wherein on both rods or only on the rod of the first piston there is a return spring made with possibility of movement in working chambers separated by a partition with a central hole, in which there is a bushing for the passage of the rod of the second piston, equipped with cup rubber seals for the tightness of the working chamber of the first piston, wherein working chambers of first and second pistons are communicated with each other via lengthwise through channel made in second piston rod while first piston working chamber or second piston working chamber is communicated via connecting hose with brake cylinder air duct.

EFFECT: higher efficiency of rail vehicle braking equipment system.
