A control device () for a parking brake device has an electronic device () by means of which, in the event of failure of a power supply system of a vehicle equipped with the control device () and the parking brake device during a procedure for parking the vehicle, at least one activation signal () can be output to a triggering device () of the parking brake device, so that the triggering device () can be activated by means of the at least one activation signal () and the parking brake device can be transferred to a locking mode by means of the activated triggering device (), such that the vehicle is locked in its current parking position by means of the parking brake device present in its locking mode.

Control device and method for operating a parking brake device of a vehicle

Systems and methods related to activating a parking lock system in the drive train of a vehicle having at least one electrical machine comprising a transmission which is connected to driven wheels. The method includes comparing a rotational speed nof the at least one electrical machine with the transmission to a predetermined threshold value for a limiting speed n, triggering, in the event that the rotational speed nis below the threshold value for the limiting speed n, a command for the actuation of an actuator system for activating the parking lock system, triggering, in the event that the rotational speed nexceeds the threshold value for the limiting speed n, a command for preventing an actuation of an actuator system for activating the parking lock system, and miming through a second comparison stage so long as n&#x2265;n.

The present invention relates to a device for blocking a transmission comprising an actuation mechanism, which is arranged inside the transmission in an at least partially oil-filled transmission chamber, and a drive of the actuation mechanism, wherein the drive is arranged outside of the at least partially oil-filled transmission chamber.

The invention relates to an electrical motor (), comprising a shaft (), a housing () with a housing flange () and a bearing plate () with a bearing plate flange (), whereby one end of the shaft () projects out of the bearing plate (). The housing flange () and the bearing plate flange () are connected by means of at least one hollow rivet () such that the electrical motor () may be mounted by means of a fixing element, in particular, a screw, through the hollow rivet () on a connector flange of a gear stage in a working connection with the projecting end of the shaft (). In one method for connection or said electrical motor () to a connector flange, the electrical motor () may be mounted by means of a fixing element, through the hollow rivet () on a connector flange of a gear stage in a working connection with the projecting end of the shaft ().

Device for maintaining the position of a rotatably or displaceably mounted shaft, particularly an armature shaft () of an electric motor (), wherein a gripping body () is arranged around the shaft (), and said gripping body is impinged upon by a force () in order to form a friction closure between the gripping body () and the surface () of the shaft (), wherein the force () for maintaining the position is provided by an actively actuated control member () that is connected at least to one end () of the gripping body ().

The invention concerns a load torque lock for automatically locking load-side torques in the case of a decrease or cessation of a drive-side torque having a housing () fixed to a frame, a locking ring () permanently connected to it and a locking body () cooperating with it and revolving on the drive side, with locking devices which, on the one hand, clamp on the locking ring () with the occurrence of a load torque by swiveling the locking body () by means of locking elements () of the output shaft () and, on the other hand, release from the locking ring () by swiveling the locking body () back by means of driving elements () of the drive shaft (). To avoid undesired friction or defective jamming of the locking devices on the locking ring () by the centrifugal forces of the locking body () it is embodied in such a way that its mass center of gravity (M) lies in the area of the rotational axis of the drive shaft and the output shaft that are aligned with one another.

The invention is based on a device for actuating a clutch ( ), in particular for motor-vehicle drives, having an electronically controllable clutch servo unit ( ) that comprises an electric motor ( ) and a reduction actuator gear ( ) having two gear elements arranged coaxially in relation to each other ( and/or and/or ) that are interconnected with each other in terms of propulsion via a thread ( ) and that are displaced axially in relation to each other when they rotate relative to one another, whereby one of the gear elements ( ) is immobilized axially in a housing ( ) of the clutch servo unit, and the actuating motion of the other gear element ( ) is transferred to a throwout bearing ( ) of a clutch disk. It is proposed that the gear element ( ) that is axially displaceable relative to the housing ( ) is interconnected via a longitudinal guide ( ) with a rotor ( ) or a motor shaft ( ) of the electric motor ( ) in a fashion that is torsion-resistant but axially displaceable, and acts on the throwout bearing ( ) via an actuator ( ).
