Abstract: The invention relates to a freewheeling element comprising a cage, a plurality of clamping bodies, each of the clamping bodies being received in an associated clamping body pocket formed in the cage, and a plurality of rolling bodies, each of the rolling bodies being received in an associated rolling body pocket formed in the cage, the cage having a higher resilience than the clamping bodies and the rolling bodies.

Abstract: A clamping body freewheel unit and a drive device for motor-assisted driving of an electric bicycle having a clamping body freewheel unit. The clamping body freewheel unit includes a plurality of clamping bodies by which force transmission between an inner shaft and an outer shaft, coupled together via the clamping body freewheel unit, is allowed only in one of two opposite directions of rotation, a cage by which the plurality of clamping bodies of the clamping body freewheel unit are kept together at a defined spacing in a circumferential direction, and a plurality of rolling elements by which the inner and outer shafts are mounted rotatable relative to one another when the inner and outer shafts are coupled together via the clamping body freewheel unit, wherein at least some of the plurality of rolling elements and the clamping bodies are held jointly on the cage.

Abstract: A sealing element for sealing a cylindrical inner surface of a first machine component and a cylindrical outer surface of a second machine component includes an inner ring, an outer ring arranged coaxially with respect to the inner ring, and a sealing gap, which is formed by an exterior lateral face of the inner ring and an interior lateral face of the outer ring. In an axial section through the common axis of the inner ring and the outer ring the sealing gap has a profile having an inlet section as a first end portion of the sealing gap having a first radius to the common axis; an outlet section as a second end portion of the sealing gap having a second radius to the common axis, wherein the second radius is smaller than the first radius; and a meander section, which adjoins the inlet section and which has a monotonically decreasing radius.

Abstract: The invention relates to a free-wheel, in particular a pinch roller free-wheel or a pinch body free-wheel, comprising relatively-rotating elements arranged one within the other on a common axis, which form a gap, in which pinch elements, in particular pinch rollers or pinch bodies, are arranged such that a friction connection can be produced with the facing outer surfaces of the elements, by means of the pinch surfaces, whereby the free-wheel outer rim is covered by a ring of fibre-reinforced plastic and the external diameter of the ring of fibre-reinforced plastic is about 1.3 to 1.8 times the diameter of the external clamping surface.
