    摘要： A ball screw includes a spindle element which has a first groove arrangement on an outer circumferential surface, a nut element which surrounds the spindle element and has a second groove arrangement on an inner circumferential surface, and a plurality of balls, at least some of which engage into the first groove arrangement and the second groove arrangement. The nut element is rotatable about an axis of rotation with respect to the spindle element, and, during the rotation of the nut element about the axis of rotation with respect to the spindle element, the balls which engage into the first groove arrangement and the second groove arrangement roll in the first and the second groove arrangement, while at the same time rotate about respective ball axes of rotation. In this case, there is provision, with respect to the ball axis of rotation, for an effective ball rolling radius with which the balls roll in the first groove arrangement to be smaller than the effective ball rolling radius with which the balls roll in the second groove arrangement.

    摘要： A gearshift mechanism for a motor vehicle with hydraulically actuated multiple clutch, particularly a twin clutch, has a first gear input shaft to drive a first group of gears and a second gear input shaft to drive a second group of gears. The two gear input shafts are each assigned a clutch unit being coaxial to one another. A stationary housing accommodates the two clutch units. At its end face, the housing can be closed off by a housing cover that has a central opening through which a drive hub of a clutch cage is guided. The housing cover is provided with a bearing flange around the central opening, on the outside of which the clutch cage is supported. This advantageously supports the clutch on the housing and makes it possible to achieve a support effect for a dual mass flywheel or the crankshaft end of the internal combustion engine.

    摘要： In order to manufacture joint-adapters for doubly curved and preferably single-layer lattice girders with improved strength and lesser weight while at the same time also allowing relatively high curvatures of the lattice girders, the invention suggests to make the joint-adapters 11 predominantly frusto-conical. Their plane rest surfaces 22 for the butt ends of the bars 10 of the lattice girder subtend the same or substantially the same slope angle .alpha. with the extended joint-adapter main axis 16 as the residual part of the joint-adapter wall. The slope angle .alpha. of the rest surfaces 12 relative to the extended joint-adapter main axis 16 determines the curvature of the lattice girder. In the preferred embodiment mode of the invention, the wall thickness of the frusto-conical joint-adapter 11 is of constant thickness over the entire height H at its thinnest sites in the vicinity of the rest surfaces 12.
