Abstract: A redundant brake control system for a locomotive consist that employs corresponding air brake control units in each locomotive that are interconnected by an inter-unit cable extending between the locomotives. Power to the air brake control units may be selectively connected and disconnected to select which air brake control unit is controlling the brakes of the train. The electronic brake valves associated with the air brake control units remain powered so that braking command may be send from either electronic brake valve and responded to by whichever of the air brake control valves have been provided with power. The control of power may be performed by the locomotive control system so that an operator can easily switch control between the air brake control units from the cab of any locomotive in the consist.
Abstract: A method for decreasing brake-pressure of an electronically slip-controllable power braking system (ESPBS) and an ESPBS. The wheel-brake pressure is generated by electronic activation of a drive motor (DM) of a pressure generator (PG) (external force). The driver indicates braking intention by actuating a master brake cylinder, which is set indirectly by a control unit via electronic activation of the DM. Plunger devices (PDs) include a plunger piston (PP), accommodated moveably in a plunger cylinder (PC). Driven by the DM, PP and PC execute a translational movement in relation to one another. A pressure buildup/decrease is performable in a BC connected to the PD as a function of movement direction. To avoid pressure medium contaminated with gas entering the BC undetected during pressure decrease after cancellation of the intention, actuation of the PD in the pressure-decrease direction is performed until the BC pressure has dropped to a pre-determinable threshold and ended.

Abstract: A hydraulic valve includes a closure member, wherein the closure member is actuable toward an opening sealed thereby in the valve, but is unconstrained to move with respect to the opening when the valve is in a closed position. In an aspect, the closure may be a thin disk, in the shape of a flat washer, which is located between the valve and piston of a hydraulic damper, and when the valve is positioned away from an opening through the piston by virtue of differential pressure across the valve in a dampening r rebound stroke, the disk is free to rotate, move from side to side, and move away from and toward the piston. By employing such a disk, sympathetic vibrations in the damper created during compression events are eliminated.

Abstract: Disclosed is a brake control apparatus which starts ABS control on the basis of slip ratio speed and which reduces a variation in the slip ratio at the time of start of the ABS control. A brake ECU computes a braking stiffness BS** in a linearly increasing region of a ?-S characteristic, and computes a slip ratio speed reference value dSref**/dt by dividing a changing speed dFxc**/dt of braking force of a wheel by the braking stiffness BS**. The brake ECU computes, as a slip ratio speed threshold, a value ((dSref**/dt)+dSn) by adding a slip ratio speed noise offset value dSn to the slip ratio speed reference value dSref**/dt and starts ABS control when the slip ratio speed dSc**/dt of the wheel exceeds the slip ratio speed threshold.
