Abstract: A brake ring for brake disks, especially disk brakes for rail vehicles, consisting of two annular bodies (2, 3) arranged adjacently at a distance from each other, having stud bolts (7) bridging the distance and rigidly connected with the annular bodies (2, 3). These stud bolts are so arranged, for the purpose of the most even distribution possible, that their axes (8) extend through the intersecting points of three systems of straight lines (9, 10 and 11) extending in one radial plane. The straight lines of the first system (9) are parallel and are at an equal distance from each other, the second system of straight lines (10) is formed by a rotation by 60.degree. and the third system of straight lines is formed by a rotation by 120.degree. of the first system of straight lines (9). Preferably, the ratio of the distance (A) of the stud bolt axes (8) and the diameter (D) of the stud bolts (7) is approximately 1.7. The brake ring has only minor aeration losses but high heat transmission by cooling air.

Abstract: Brake linkage for vehicle friction brakes is actuated by a brake power motor (6) and comprises a vent play regulator (10) having an adjustment element driven by an auxiliary motor (14). At the start of braking, the auxiliary motor (14) is actuated in advance of the brake power motor (6), causing application of the vehicle friction brake through the adjustment element. The brake power motor is then activated and tightly clamps shut the friction brake. The brake linkage is particularly suitable as a brake clamp (5) for disc brakes, the vent play regulator then being integrated into the pull rod (11).

Abstract: A pulsating brake accelerating device for an indirectly operating air brake for rail vehicles has a pulsator (12), which is attached to the brake pipe (BP) via a jet (23). The pulsator (12) forms a mixed pressure from two pressures. One of the pressures is formed by the pressure of the brake pipe (BP) via a jet (23) and the other pressure is formed by pressure from a control chamber (QAC) via another jet. At every braking level the pulsator (12) drains mixed pressure pulses off into the atmosphere, while at the same time the brake pipe pressure and the control chamber pressure is lowered via the mixed pressure pulsator (12). The mixed pressure can consist of two valves (14, 15). The control element (4) of the brake accelerator unit can be the emergency brake piston, which monitors several valves, one of which is the pulsator-excitation valve (8).

Abstract: Hydraulic vehicle brake comprising a hydraulic accumulator (1), a brake valve adjustment device (4) supplied thereby, and a brake pressure line section (7) to the brake cylinders attached to the latter via an emergency brake valve (6). In the emergency braking position of the emergency brake valve, this connection is broken, and the brake pressure line section is directly connected to the hydraulic accumulator via a nozzle (10) which is bridged by a cylinder (13) in which a piston is sealingly displaceable. A spring (17) biases the piston in the displacement direction to the accumulator side end connection (11) of the cylinder. During emergency braking, the piston (14) first forces an amount of hydraulic medium sufficient for brake application out of the brake cylinder side chamber (16) of the cylinder (13). This is followed by a damped increase in brake pressure through additional supply of hydraulic medium from the hydraulic accumulator (1) through the nozzle (10) into the brake cylinders.

Abstract: Brake control valve system for rail vehicle air brake, comprising an emergency brake piston (7) having a first piston chamber (9) loaded by the quick action chamber with a much greater volume than its second piston chamber (8) loaded by the brake line. The effective pressure surfaces of the service brake piston and emergency brake piston are substantially identical. The emergency brake piston controls a first quick action exhaust valve (15) for venting smaller amounts of quick action air per unit of time, as well as a valve device (14) containing a second quick action exhaust for venting larger amounts of quick action air. Valve device (14) is pneumatically connected to the control piston (19) of a high pressure/emergency exhaust valve system (16) which operates only upon emergency braking. Piston (19) contains a nozzle (22) through which pressure remaining in the quick action chamber (10) during emergency braking is evacuated in a predetermined time.

Abstract: The present invention discloses a maximum pressure control device for the brake cylinder pressure that is to be supplied to a brake cylinder and this device can consist of two separate pressure control devices or be constructed as a unified, reversible pressure control device. The selection of one of the active pressure control devices or changeover of the switchable maximum pressure control device results from a main brake line pressure acting against a spring loaded control piston which, depending on the main brake line pressure, can switch off the pressure control function of the maximum pressure control device for the low (service) or high (emergency) brake cylinder pressure. The control piston when functioning as an actuated cut off device can be mechanically coupled with a pressure control device by means of a stop coupling or pneumatic coupling. As a result, the control piston is not able to exert any negative effect on the control precision of the maximum pressure control device.

Abstract: Disc brake for rail vehicles having a brake clamp (7) located in one plane and having two brake levers (4) having their central portions connected by a pull rod (5). The latter is formed with a rotatable threaded spindle (9) as a stay, which spindle is rotatable from the brake cylinder (15) by means of a turning lever having a play adjustment device. The axle (16) of the brake cylinder (15) extends perpendicularly to the plane (8) of the brake clamp (7) between the two brake levers (4) and between the pull rod (5) and a bearing block (6) for the brake lever ends, at a distance from the brake disc. The brake cylinder (15) carries the bearing block for the brake lever ends and a carrier arm (22) for the pendulum suspensions (24) of the brake shoes (2).

Abstract: A pressure control valve for the compressed air brakes of a railway vehicle includes a triple pressure control valve with a constant pressure chamber, a selector valve and a selector reservoir. Upon the occurrence of pressure reductions in the main brake line for service braking, the selector valve selector remains at rest. When stronger pressure reductions in the main brake line occur, the selector valve evacuates the selector reservoir which lags in relation to the main brake line pressure as result of the force exerted by a pre-stressed spring until a specific minimum pressure is attained by a retention valve. In a subsequent brake release, the selector valve will produce a pressure balance between the constant pressure chamber and the selector reservoir to facilitate the brake release process and a balancing or proportioning of the pressure control valve at an optionally reduced normal pressure head in the main brake line.

Abstract: A pulsating brake accelerating device for an indirectly operating air brake for rail vehicles has a pulsator (12), which is attached to the brake pipe (BP) via a jet (23). The pulsator (12) forms a mixed pressure from two pressures. One of the pressures is formed by the pressure of the brake pipe (BP) via a jet (23) and the other pressure is formed by pressure from a control chamber (QAC) via another jet. At every braking level the pulsator (12) drains mixed pressure pulses off into the atmosphere, while at the same time the brake pipe pressure and the control chamber pressure is lowered via the mixed pressure pulsator (12). The mixed pressure can consist of two valves (14, 15). The control element (4) of the brake accelerator unit can be the emergency brake piston, which monitors several valves, one of which is the pulsator-excitation valve (8).

Abstract: In a brake system the actuator pressure is controlled using a closed loop feedback system where, a system pressure, indicated by a pressure transducer is compared with a predetermined reference value. During the individual control routines, pressures corresponding operation times of inlet and outlet valves are stored in a memory. In the event of a failure of the pressure transducer, a switch is made to an open loop control mode where, starting from a previously established reference pressure, the system pressure can be read from the memory and controlled by appropriate operation of the inlet or outlet valves, to achieve the desired level.

Abstract: A brake lining carrier has a base plate one side of which can be detachably mounted on a brake lining support member and on the other side thereof is a layer of resilient material upon which are positioned a plurality of brake lining elements disposed to define a friction braking surface. A frame is provided on the edge portion of the base plate to enclose the brake lining elements. Each brake lining element is mounted upon a carrier plate which has projecting flange portions on two longitudinal sides of the brake lining element. The flange portions on the outer longitudinal sides are received within a groove formed in the frame and the flange portions on the inner longitudinal side extend into an open central portion of the friction lining block in which there is a clamp exerting a force against the inner flange portions in a direction perpendicular to the friction surface.
