An angle drive with two shafts () which are drivingly connected to one another and whose axes (A, A) intersect one another at an angle, wherein on each of the shafts () there is firmly arranged at least one gearwheel () and wherein there is provided a hollow gear () with an axis of rotation (A) and wherein the gearwheels () engage the hollow gear ().

Angle drive

An axial adjusting device includes two discs which are rotatable relative to one another and coaxially supported relative to one another, between which two discs balls are guided in pairs of ball grooves. The depth of the pairs of ball grooves is variable across the circumference of the discs. One of the discs is axially supported and one is axially displaceable against resilient returning forces of a first spring mechanism. At least one of the discs can be driven by a motor via a gear drive. A second spring mechanism is provided which&#x2014;during the return motion of the discs, after the balls have reached their end positions in the ball grooves, which end positions are determined by the greatest groove depth&#x2014;permit the drivable disc to overshoot against the resilient returning forces of the second spring mechanism.

Axial adjusting device with spring support during the return motion

The invention relates to a gearbox switchable under load, which has an input shaft coupled to at least one further shaft, which extends parallel to the input shaft, via pairs of gearwheels to achieve different gear stages. One gearwheel of each pair of gearwheels is rotatively fixedly connected to one of the two shafts and the other gearwheel of each pair of gearwheels is optionally rotatively fixedly connectable to the other of the two shafts by a respective friction coupling. Also, in the gearbox, the input shaft is rotatively fixedly connected to an engine shaft; mechanism to reverse the direction of rotation is provided in the torque flow from the input shaft to the output pinion; and mechanism for approximately simultaneously loading the friction couplings of the two lowest gear stages is provided and for starting purposes when driving forward and reversing, the torque flow through both friction couplings is maintained, at most, until an identical speed has been reached between the elements of the friction coupling of the lowest gear stage.

Gearbox switchable under load

A switchable differential drive, preferably for a vehicle driven by an electric motor, has a differential drive housing, a drivable differential carrier rotatably supported in the housing, two axle shaft gears supported therein, which are connected to output shafts extending out of the differential carrier and which are connected to one another via differential gears. A first output shaft is designed directly as an axle shaft and a second output shaft is coaxially supported in the first axle shaft. Two switching couplings are arranged coaxially relative to the latter axle shaft. To obtain a first gear stage, the first switching coupling is engaged, thereby non-rotatingly connecting the output shaft to the axle shaft, while the second switching coupling is open. To obtain a second gear stage with one wheel drive, the second switching coupling is engaged, thereby non-rotatingly connecting the output shaft to the differential drive housing while the other switching coupling is open.
