Abstract: A locking arrangement for locking the mobility of a first element which is movably mounted in a first direction, by means of a second element which is movably mounted in a second direction transversely with respect to the first direction. The first element has a toothed contour with at least two teeth and a tooth gap which lies between them. Tooth gap has a tooth gap length in the first direction. The second element has a projection which has, in the first direction, a projection length which is shorter than the tooth gap length. The projection can be introduced into the tooth gap when there is a movement in the second direction, in order to lock the first element. The teeth each have a face which points towards the second element and has a first contour. The projection has a face which points towards the first element and has a second contour.

Abstract: A gear support comprises an elongate carrier portion which is oriented along a longitudinal axis, and a flange portion at one end of the carrier portion. The flange portion serves for fastening the gear support to a case of the gear, and a bearing portion in the region of an opposite end of the carrier portion serves for mounting the gear support on the motor vehicle. The carrier portion has two mutually opposite longitudinal spars, between which ribs extend, the longitudinal spars and the ribs being produced in one piece with one another.

Abstract: A step-by-step variable transmission has a housing, a drive input shaft device, a drive output shaft and a countershaft. A plurality of gearwheel sets are mounted on the drive input shaft and on the countershaft. The gearwheel sets can be shifted so as to establish different gear stages by means of respective shift clutches. The countershaft is connected to the drive output shaft by means of a drive output constant wheel set. The drive output shaft is rotatably mounted in the region of its opposite ends on the housing by means of two bearings. At least one of the gearwheel sets is mounted in the region in the axial direction between the two bearings of the drive output shaft.

Abstract: A method for controlling an automated step-by-step variable transmission which has a plurality of gear stages which set up a different transmission ratio in each case. The method comprises the steps: a) detecting whether a gear stage is to be engaged, b) detecting an input actual variable which is substantially proportional to an input rotational speed of the step-by-step variable transmission, and an output actual variable which is substantially proportional to an output rotational speed of the transmission, c) checking as to whether a difference between a ratio of the input and the output actual variables and the transmission ratio which would be set up by the gear stage is smaller for a predefined timespan than a predefined tolerance range, and d) determining a fault state if the difference does not lie within the tolerance range for the predefined timespan.

Abstract: A lock arrangement for a transmission, in particular in the form of a parking-lock arrangement for an automated transmission. The lock arrangement is prestressed by a first spring accumulator into a locking position in which the transmission is locked. The lock arrangement is capable of being shifted by means of an actuator from the locking position into a release position in which the transmission is released. The lock arrangement has an electronically activatable blocking device which is designed for blocking the lock arrangement mechanically in the locking position.

Here, the safety valves are designed in each case as proportional pressure regulating valves.

Abstract: A dual clutch arrangement for a dual clutch transmission for motor vehicles, having a first and a second friction clutch which are each fluidically actuable. A first piston arrangement serves to actuate the first friction clutch and has a first piston, a first piston space and a first centrifugal force equalizing space. A second piston arrangement serves to actuate the second friction clutch and has a second piston, a second piston space and a second centrifugal force equalizing space. The piston spaces and the centrifugal force equalizing spaces are situated in each case on opposite sides of the associated piston and are connected by means of feed lines to a valve arrangement.

The variator disk has a curved running surface which is oriented coaxially with respect to a variator axis and on which rollers of the toroidal variator can roll. The variator disk having furthermore at least two partial disks which are designed as a traction disk, on which the running surface is formed, and as a supporting disk, respectively. The supporting disk is designed for supporting axial forces applied to the running surface. The traction disk is supported on the supporting disk in the radial direction to the variator axis.

Abstract: A transmission configuration includes an automated dual-clutch transmission having two transmission sections with respective input shafts, respective output shafts and respective motor clutches. The motor clutches are connected, on a motor side thereof, to a drive shaft and to a respective one of the input shafts on a transmission side thereof. A drive-side speed sensor unit is disposed at the drive shaft. An input-side speed sensor configuration includes sensor wheels connected, fixed against relative rotation, to respective ones of the input shafts, and pulse sensors disposed stationary with respect to a housing and within an effective range of the respective sensor wheels. The input-side speed sensor configuration is configured to detect a speed of the input shafts and a direction of rotation of at least one of the input shafts.
