Abstract:
A drive assembly for the driveline of a motor vehicle with an axle which can be driven when required. The drive assembly includes a drive and a multi-plate coupling. The drive comprises a drive housing with a sleeve-shaped projection in which a drive input shaft is rotatably supported. The multi-plate coupling which is rotatably supported in a coupling housing connected to the drive housing comprises a coupling input part for introducing torque and a coupling output part connected to the drive input shaft in a rotationally fast way. The multi-plate coupling is arranged coaxially on the outside relative to the sleeve-shaped projection and partially axially covers the latter.
Abstract:
The invention relates to a controllable viscous coupling for generating a locking effect between two coupling parts rotatable relative to one another around a common longitudinal axis, more particularly for the driveline of a motor vehicle. The viscous coupling comprises a first coupling part, a second coupling part, wherein the first and the second coupling part form a sealed annular chamber. First plates are connected to the first coupling part in a rotationally fast way and second plates are connectable to the second coupling part in a rotationally fast way, as well as controllable connecting means to allow switching between an open position in which the second plates are freely rotatable relative to the second coupling part, and a closed position in which the second plates are connected to the second coupling part in a rotationally fast way.
Abstract:
A shaft coupling having two attachment elements that are rotatable relative to one another and that are connected to one another by a rotationally resilient assembly, and further having a dampening device which is active between the attachment elements for the purpose of suppressing torsional vibrations of the rotationally resilient assembly is disclosed. The rotationally resilient assembly comprises two ramp discs that are rotatable relative to one another and that support one another at least indirectly. One disc is supported in a rotationally fixed and rigid manner on one of the attachment elements and the other disc is supported in a rotationally fixed and axially resilient manner on the other one of the attachment elements by a spring. The dampening device is a viscous coupling having a hub connected to one of the attachment elements and a housing connected to the other one of the attachment elements.
Abstract:
A differential drive having a drivable differential carrier rotatably supported in a drive housing, said differential carrier comprising a carrier portion and two cover parts. Two axle shaft gears are coaxially rotatably supported in the differential carrier. Further, two sets of differential gears are slidingly received on their tooth heads, in axis-parallel cylindrical bores in the carrier portion. The axis-parallel cylindrical bores are in the form of through-bores in the carrier portion. The differential gears comprise spacing journals with ends having friction bearing portions. Corresponding friction bearing sections are formed in the differential carrier, axially adjoining the carrier portion.
Abstract:
The invention relates to a locking device 4 for a freewheeling unit 1 of a non-directly driven axle of a motor vehicle driven by a directly driven axle. To lock the freewheeling unit 1 there is provided a first drive element 2 with a number of circumferentially distributed apertures 15 holding radially displaceable locking elements 16. The locking elements, for the purpose of establishing a non-rotating connection between the first drive element 2 and the second drive element 3, may partially enter recesses 17 of the second drive element 3 corresponding to the apertures. Radial displacement of the locking elements 16 is achieved by a spring loaded axially movable control element 10. Displacement of the control element 10 is achieved by radially outward displacement of centrifugal masses 20.
Abstract:
The invention relates to a drive assembly for a four wheel drive vehicle with the distributor assembly for distributing driving torque arranged between the front wheels and the rear wheels of a driving axle. A distributor differential (13) and axle differential (15) distribute the driving torque. Both the distributor differential (13) and the axle differential (15) may be at least partially locked via viscous couplings (39, 40) in order to cancel the differential function. I order to achieve the shortest possible design, the two viscous couplings (39, 40) are arranged coaxially one inside the other.
Abstract:
A differential drive having a drive housing in which a drivable differential carrier is rotatably supported and which comprises straight-toothed and helically toothed output gears connected to each other via differential gears which are axis-parallel thereto and of which a first group engages the one output gear and a second group the other output gear, with each of the differential gears of the one group engaging at least one of the differential gears of the outer group and with the differential gears, with their tooth heads, being held in partially cylindrical apertures of the differential carrier, with the axial length of at least some of said apertures being greater than the toothed region of the group of differential gears held therein, and with the apertures whose axial length is greater than that of the toothed region of the differential gears containing disc-shaped stop elements which extend radially inwardly beyond the inner cross-section of the apertures and which are axially supported on at least one of the output gears.
