Document Type and Number:
Japanese Patent JPH08507023
Kind Code:
A
Abstract:
Associated with at least one wheelset (4, 5, 6, 7) of the rail vehicle described is a brake system (15) including a hydrostatic pump (17) with a closed pressure-medium circuit (34) and with at least one rotary piston (20, 21) coupled by a drive link to the wheelset axle (12). The brake system also includes a throttle (37) to cut off the pressure-medium circuit and brake the driven rotary piston (20, 21), plus means (38) for cooling the pressure medium. The mode of operation of the pump (17) can be switched, by means of a switchable coupling, between a mode in which the pressure medium is circulated and the brake system (15) activated and an idle mode in which the pressure medium is not circulated. The brake system (15) requires little space and is suitable for long braking periods.
