Abstract: A transmission for a drivetrain of a motor vehicle, including a transmission casing which is or can be at least partially filled with oil and wherein a parking lock is arranged, wherein the parking lock includes a parking lock gear, which is connected rotationally conjointly to a transmission shaft and which has a locking toothing, and a locking pawl, which is mounted pivotably on the transmission casing and which has a locking tooth which, when the locking pawl is pivoted into a locking position, can be placed in positive locking engagement with the locking toothing of the parking lock gear, wherein the locking pawl is actuatable by an electromechanical parking-lock actuator which is arranged within the transmission casing. The invention furthermore relates to a motor vehicle which has a transmission of the type.

Abstract: An electric parking brake actuator has a transmission mechanism, which is rotationally drivable by an electric motor and converts rotational movement into an axial movement of an actuating rod that carries an actuating element for the parking brake. The actuating rod normally moves by electric motor displacement via the transmission mechanism from an unblocking position to a blocking position and vice versa. A blocking mechanism serves the purpose of holding the actuating rod in the unblocking position of the actuating rod against the force of a spring element. A blocking disc, which is in drive connection with the transmission mechanism, has a stop surface for a locking device in only one rotational direction of the blocking disc. For secondary alternate operation the stop surface is releasable by the locking device so that the actuating rod is biased by the spring element to the blocking position without electric-motorized assistance.

Abstract: An actuating device for hydraulically actuating at least one setting element comprising a pump, which has an electric pump drive, with reversible pumping direction, at least one double-acting piston-cylinder arrangement, which is connected therewith and the piston of which is operatively connected with the setting element, and a hydraulic fluid reservoir from which the hydraulic fluid can be pumped to the piston-cylinder arrangement in order to hydraulically load the piston thereof for a setting element movement depending on pumping direction on one (effective surface 22) or other (effective surface 24) side. In this connection, the piston-cylinder arrangement is functionally associated with a detent device with a blocking element, which is spring-biased into a blocking position preventing setting element movement and is movable by an electrically activatable actuator from the blocking position into a release position permitting setting element movement.

Abstract: A reducing agent pump has a pump inlet part and a pump outlet part closing off the pump body at its ends. One or both of the inlet and outlet parts is of two-part construction, with a closure element and another element. The two elements are prestressed relative to one another with a spring element, so that in the event of a pressure which exceeds the spring force of the spring element, a relative movement can be carried out between the two elements of the two-part member. This makes it possible to absorb an increase in the volume of the reducing agent inside the pump body caused by freezing and therefore to prevent damage to the reducing agent pump.
