  • Patent number: 9897206
    Abstract: An actuator for activating a parking lock, in particular for automatic transmissions in motor vehicles, includes a hydraulic piston which is guided in a cylinder and which activates a locking pawl for a parking lock wheel in the transmission by way of an actuating rod. The piston disengages the parking lock against the force of a preload spring which engages the parking lock in the pressureless state. An electromagnetically activated locking device can positively secure the piston in the disengaged position, with the locking device securing the piston relative to a guide sleeve attached to the cylinder with radially extendable locking elements. To improve system protection, the piston can also be secured in a positively locking fashion by the locking device in the position corresponding to the engaged state of the parking lock.

  • Patent number: 9797460
    Abstract: A clutch apparatus is disclosed having concentrically spaced inner and outer clutches. The inner and outer clutches are coupled for rotation via a coupling ring. The present invention is well suited to a configuration wherein one of the clutches is dynamically actuated and one of the clutches is manually disengageable by the operator using a clutch lever. In this configuration, the operation of the clutch lever by the operator is unaffected by the dynamically actuated clutch. The concentric configuration of the clutches is beneficial in allowing the improved clutch to occupy a similar space compared to a traditional clutch mechanism.

  • Patent number: 9702417
    Abstract: A method of calibrating a hydraulically operated clutch in a continuously variable transmission of a vehicle, includes steps of filling the clutch as if for a shift, using a control signal value for achieving a test pressure, and determining a resulting change in a pressure condition in a hydrostatic power unit of the transmission. If the change indicates initial engagement, then a value representative of the signal value used is recorded. If greater than initial engagement is indicated, or the vehicle moved, then the clutch is emptied and tested using a lower test pressure. If initial engagement is not indicated, the clutch is emptied and refilled to a greater test pressure. An exemplary pressure condition is a difference in pressure in lines between a pump and motor of the power unit. During the calibration, the vehicle can be held stationary with a parking brake or the like.
