Abstract: A roller bearing for linear movements has two guide members arranged coaxially relative to each other between which there are provided races for roller members extending in the longitudinal direction. The roller members are biased in radial direction by at least one elastic element. The races for the roller members are shaped as guide surfaces directly at the two guide members, and the elastic element is provided radially offset with regard to the guide surfaces and acts by means of webs only indirectly onto these surfaces, by being subjected to a radial clamping force of a further annular element.

Abstract: Axial actuator for converting a rotary motion into a translational motion, in particular for controlling the axial position of variator disks of an infinitely variable vehicle transmission (continuously variable transmission or CVT), which has the following features: a shaft, a control element, which is fixed axially relative, to the shaft, can be rotated about the axis of the shaft by means of a driving device and has a rear end and a front end, with a linear-motion element, which is mounted rotatably relative to the control element, is fixed in terms of rotation relative to the shaft and has a rear end and a front end, with a flanged cage, which is arranged between the control element and the linear-motion element, preferably carries rolling-contact elements and has spiral flanges, at least three concentric, spirally or helically rising ramps facing the rear end of the linear-motion element being arranged at the front end of the control element, and at least three concentric ramps, which face the front end

Abstract: A drive device for a current-generating unit suitable for use in motor vehicles has a freewheel, between a driving part and a driven part, for the purpose of damping out rotational oscillations, as a result of which load peaks are reduced and service life is increased.
