20110290615 | PARKING BRAKE ASSEMBLY WITH EMERGENCY UNLOCKING MECHANISM - A parking brake assembly for the driveline of a motor vehicle is disclosed. The parking brake assembly comprises a locking mechanism, an actuator and an unlocking mechanism. The locking mechanism is able to inhibit and release the rotational movement of a shaft in the driveline of a motor vehicle. The actuator actuates the locking mechanism. The locking mechanism comprises a locking element which is linearly movable by the actuator, and a latching element which cooperates with the locking element. The locking element can be transferred into a first axial position in which the latching element assumes a releasing position in which the shaft is rotatable, and wherein the locking element can be transferred into a second axial position in which the latching element assumes a closing position in which the latching element inhibits a rotational movement of the shaft. The unlocking mechanism forcibly unlocks the locking mechanism. The unlocking mechanism comprises an unlocking element for rotating the locking element, wherein, in the second axial position, the locking element can be transferred into a first rotational position in which the locking element holds the latching element in the closing position, and wherein the locking element can be transferred into a second rotational position in which the latching element can assume a releasing position. | 12-01-2011 |
20120011952 | ANGLE DRIVE ASSEMBLY - The disclosure relates to an angle drive arrangement for a drive train of a motor vehicle having a permanently drivable first drive axle and a switchable second drive axle. The angle drive arrangement comprises an input shaft and a shift clutch. The input shaft can be driven in rotation about a first rotational axis. The shift clutch is arranged coaxially with respect to the first rotational axis and which has a clutch input part and a clutch output part which can be coupled to one another in order to transmit a torque. The angel drive arrangement further includes an angle gearing with a crown gear, which is arranged coaxially with respect to the first rotational axis, and a pinion, which is mounted so as to be rotatable about a second rotational axis and which is in meshing engagement with the crown gear. The second rotational axis is arranged at right angles to the first rotational axis; wherein the crown gear is fixedly connected to an intermediate shaft which is mounted in a housing by first and second bearing mechanisms so as to be rotatable about the first rotational axis. The first and second bearing mechanisms are arranged on the same side in relation to the second rotational axis. | 01-19-2012 |
20120115665 | PARKING LOCK FOR A MOTOR VEHICLE AND METHOD OF OPERATING A PARKING LOCK - A parking lock assembly for a motor vehicle is described that has at least one electrically drivable driving axle. The parking lock comprises an electric drive, a shaft which is arranged in the driveline of a motor vehicle and which is drivable by the electric drive, as well as a locking mechanism which is controllable in the locking sense in order to prevent a rotational movement of the shaft and which is controllable in the opening sense in order to release the shaft. The electric drive is controllable in order to transmit torque to the shaft if, in spite of the locking mechanism being controlled in the opening sense, the shaft is prevented from carrying out a rotational movement. Furthermore, a method of actuating such a parking lock assembly is described. | 05-10-2012 |
