Abstract: An angle drive with two shafts (12, 15) which are drivingly connected to one another and whose axes (A1, A2) intersect one another at an angle, wherein on each of the shafts (12, 15) there is firmly arranged at least one gearwheel (19, 20, 21) and wherein there is provided a hollow gear (17) with an axis of rotation (A3) and wherein the gearwheels (19, 20, 21) engage the hollow gear (17).

Abstract: 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—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—permit the drivable disc to overshoot against the resilient returning forces of the second spring mechanism.

Abstract: An actuating mechanism for axial setting purposes, comprising three discs which are supported co-axially relative to an axis and of which a central disc is rotatable relative to the two outer discs, between the central disc and each of the outer discs, there are arranged sets of balls, the balls each run in pairs of circumferential grooves in the faces of the central disc and of one of the outer discs facing one another, the circumferential grooves comprise a circumferentially variable depth whose extension is such that, over the entire relative angle of rotation, the first outer disc moves axially from a first end position via a central position into a second end position which deviates from said first end position, and the second outer disc moves axially from a first end position via a second end position deviating therefrom back into the first end position.

Abstract: A convoluted boot assembly particularly suited for sealing a sideshaft connected to a constant velocity joint and arranged at the axle drive of a motor vehicle, relative to the housing of the axle drive. The convoluted boot assembly includes a convoluted boot (21) which includes a first collar (22) to be secured relative to the shaft (41), a second collar (23) to be connected to the housing (51) and a boot region (24) which connects the two collars (22, 23) and serves to offset the angular movements of the shaft. The assembly also includes a protective cap (31) which is secured to the first collar (22) and which encloses the boot region (24) of the convoluted boot (21) at least substantially in the direction pointing to the second collar (23), and a bearing assembly (11) for supporting the convoluted boot (21) on the shaft (41), as well as a seal (16) for sealing the first collar (22) relative to the shaft (41).

Abstract: 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.

Abstract: 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.

The counter shaft is through an input transmission continuously frictionally connected to the input shaft which latter is adapted by a clutch element in a direct velocity stage to be coupled to said main shaft. All gears of the main shaft mesh directly or indirectly with gears freely rotatable on said counter shaft and output shaft respectively.
