Abstract: A mechanical backstop is provided which comprises a housing, an input impact gear, a frictional plate, a floating impact gear, and an output impact gear. The floating impact gear is movably mounted between the input impact gear and the output impact gear to achieve transmission. The frictional plate is fixed relative to the housing and disposed at a side of the floating impact gear close to the input impact gear. When the input impact gear transmits a torque to the floating impact gear, the floating impact gear floats toward the output impact gear to separate from the frictional plate and transmit the torque to the output impact gear. When the floating impact gear transmits a torque reversely, the floating impact gear floats toward the input impact gear to abut against the frictional plate and achieve reverse locking.

Abstract: A wheel structure includes a variable spoke configured to connect a wheel and a central shaft and having a length that varies in a radial direction of the wheel, a spoke driving unit configured to provide power for changing the length of the variable spoke in the radial direction, and a power transmission unit configured to transmit power from the spoke driving unit to the variable spoke. A plurality of variable spokes are spaced apart from one another in the circumferential direction. The power transmission unit includes an output shaft configured to rotate by receiving power from the spoke driving unit, and a clutch configured to connect the variable spoke and the output shaft and selectively transmit a rotational force of the output shaft to the variable spoke or cut off the transmission of the rotational force to the variable spoke.

Abstract: A method for controlling a hydrodynamic retarder in a motor vehicle that can be mechanically disengaged via a disconnect clutch, comprising a drive motor whose power output is controlled via an actuator such as a foot pedal or a lever; whereby in an overrun operation the acceleration of the motor vehicle is collected or detected and compared with a pre-specified acceleration value; and whereby in the non-braking mode the disconnect clutch is engaged, regardless of an initiation of a braking mode by an operator of the motor vehicle or a driver assist system and the working chamber is maintained drained when the acceleration exceeds an acceleration limit.

Abstract: A self-contained clutch for diesel engines for off-highway implementation is provided. A stationary friction disc, pressure plate and endplate sandwich a pair of rotating separator discs. Attenuation of vibration damping of the rotator discs may be achieved by a centrifugal weight. A pulse-width-modulated DC motor or valve is employed in association with a hydraulic actuator to control pressure to the clutch piston. An RFID tag uniquely identifies the nature and parameters of the clutch itself and is associated with the clutch such that the controller can most efficiently operate the clutch. Heat is dissipated by an oil pump servicing the support bearings and/or by the integration of a centrifugal fan into the heat disc stack.
