    摘要： A series hydrostatic transmission for a vehicle having a wheel where the transmission comprises a hydraulic pump and a hydraulic motor each having a pumping mode and motoring mode. The pump and motor each have cylinders of cyclically varying working volume in which hydraulic fluid displacement through each cylinder is regulated and in phased relationship to cycles of cylinder working volume with reference to a phase signal. The transmission has a first mode in which the pump and motor are fluidly connected to each other, a second mode in which energy from hydraulic fluid pressurised by the motor in the pumping mode is transferred to an energy store, and a third mode in which energy from the energy store drives the motor, and wherein the motor comprises a valve assembly disposed between a high pressure line and a working chamber of the motor.

    摘要： A hydrodynamic retarder is revealed having a rotor blade wheel and a stator blade wheel each with two different types of blading, i.e. an inner blading enclosed by an outer blading. The two blade rings are provided with blades inclined in opposite directions. This allows said retarder to be operated in both directions of rotation. A particularly advantageous development of the invention is that the retarder is operated as a counter-rotating retarder, whereby the stator is rotated in the opposite direction by means of a reversing gear. Thus, a vehicle can be hydrodynamically braked almost to standstill. When integrating the retarder into a rail vehicle, the rotor can be driven by the wheel sets separately from the stator. An identical braking effect is obtained in both directions of travel. Moreover, the inner working circuit enclosed by the outer working circuit can be arranged radially in such a manner that the radially outer front cross-sectional area for the fluid flow is of identical size as the radially inner front cross-sectional area. This prevents shock losses and increases the braking power of the retarder.

    摘要： A drive for high-speed locomotives has a variable-speed electric motor which transmits torque to the input shaft of a hydrodynamic power transmission having a hydrodynamic torque converter and a hydrodynamic coupling for transmission of torque to the output shaft which drives the wheels through the medium of a mechanical transmission and cardan shafts. The control unit of the drive engages the converter in the lowest speed range, the coupling in the highest speed range, and the coupling or the converter in the intermediate speed range. In the intermediate speed range, the coupling is engaged when the control unit ascertains that the ratio of maximum traction effort of the drive in engaged condition of the coupling at the momentary intermediate speed to the resistance which the locomotive encounters exceeds one. The resistance is ascertained automatically by determining the tractive effort of the drive in engaged condition of the converter at the momentary intermediate speed and by subtracting therefrom the accelerating force which is the product of the mass of locomotive plus cars (if any) and the momentary acceleration of the vehicle. The output shaft receives braking torque from a hydrodynamic brake whose controls include safety features to insure the application of brake in the event of failure of the primary actuating device.

    摘要： A railway vehicle having a friction braking system has a hydrodynamic braking unit enclosed in a housing mounted in the vicinity of a wheel and axle supporting the vehicle. The rotor of the braking unit is drivingly connected to the axle and a control system introduces fluid into the braking unit to achieve a braking effect. A common control device is employed for actuating the friction braking means and the hydrodynamic braking unit. The control device includes an anti-skid device and also operates to render the hydrodynamic braking unit inoperative when the vehicle is traveling at a sufficiently low speed or when the friction braking means exerts only a light braking action.
