A one-way bearing, a bearing assembly, and a free-wheeling mechanism for a bicycle are disclosed herewith. The bearing assembly, in one aspect, includes a one-directional bearing having an inner and an outer race, the one-directional bearing including a sprag clutch mechanism. The bearing assembly, according to this aspect, further includes a first thrust bearing and a second thrust bearing, wherein the inner and outer races of the one-directional bearing are formed to retain one or both of the first or second thrust bearings, and a one-directional bearing mechanism located between the inner and outer races. In at least one aspect, the inner race has a flange extending in a radially outward direction, the sprag clutch mechanism abuts the flange on an inner axial side of the flange, and the flange abuts the first thrust bearing on an outer axial side of the flange.

A hybrid module for a drive train of a motor vehicle comprises a housing, a disconnect clutch, and a hydraulic actuating unit cooperating with the disconnect clutch and received on the housing. The module includes an electric motor, wherein a rotor of the electric motor is rotationally coupled to a clutch component of the disconnect clutch. The actuating unit has a piston element, which is received such that it is displaceable relative to the housing and which, via an actuating bearing, is connected to a pressure element such that it is fixed against displacement in an axial direction of the disconnect clutch yet rotatable relative to the pressure element. The pressure element is configured for engagement and disengagement of the disconnect clutch, and the actuating bearing is formed as an axial needle bearing.

An electric actuator 1 includes: an electric motor 10; a first motion conversion mechanism 20 that has a screw shaft 21 rotatably driven by the electric motor 10 and a nut 22 screwed with the screw shaft 21, and converts a rotary motion of the screw shaft 21 into a linear motion of the nut 22; and a housing 40 accommodating the electric motor 10 and the motion conversion mechanism 20. The housing 40 includes a pair of housing split bodies 41 and 42 split by a plane parallel to an axial direction of the screw shaft 21.

A coupling device has two components which are rotatable relative to one another, a recess which is provided on the first component, and a locking element which is held movably on the second component and is movable relative to the components between a locking position in which the locking element engages in the recess and a release position in which engagement of the locking element in the recess is prevented. An actuating device is provided which is displaceable relative to the components and relative to the locking element and which has an actuating element formed from a first material, by which a movement of the locking element out of one of the positions into the other position can be effected by displacement of the actuating device. The actuating device has a main body which is formed from a second material which is different from the first material.

The invention relates to a pivot locking device of two bearing elements (102, 103) oriented towards a common axis, in which one or both bearing elements (102, 103) are pivotable about a common pivot axis (22), with a first bearing element (102), which comprises a perforation (104), with a second bearing element (103), which comprises a perforation (106), wherein the first and second bearing elements (102, 103) are oriented in alignment to one another with the perforations (104, 106), with a chamber (124) provided on the first bearing element (102), which chamber comprises a circulatory path for circulatory elements (129) and is open to the second bearing element (103) and, by a connecting surface (118) facing to the chamber (124), is closed on the second bearing element (103), with a plurality of circulatory elements (129) arranged in the chamber (124), with an catch (121) arrangeable on the second bearing element (103), which catch engages into the circulating chamber (124) and is positioned between circulatory elements (129) and, in a pivot movement of the second bearing element (103) to the first bearing element (102), displaces the circulatory elements (129) in the chamber (124) along the circulatory path, and with a locking element (107) arranged on the first bearing element (102), which locking element, in an unlocking position (109), unblocks the circulatory path for the circulatory elements (129) in the chamber (124) and, in a locking position (108) of the locking element (107), blocks a displacement movement of the circulatory elements (129) along the circulatory path of the chamber (124).

An axial rolling bearing consisting of at least one annular bearing disc which has a circumferential raceway arched in profile cross section, and consisting of a multiplicity of rolling elements formed as bearing needles or bearing rollers and arranged next to one another in a circular form, which roll on the raceway of the bearing disc and are kept at uniform distances from one another by a bearing cage. The arched raceway is formed having at least one circumferential groove-shaped depression at least in the region of one of the two ends of the rolling elements.

The arched raceway is formed having at least one circumferential groove-shaped depression at least in the region of one of the two ends of the rolling elements.

A double row axial roller bearing assembly includes a compressible ring between the two rows. This compressible ring prevents excessive axial forces if the respective shafts impact one another after becoming axially separated. One embodiment is fully unitized such that all parts of the bearing assembly remain with one of the two shafts if the shafts become axially separated. Another embodiment is semi-unitized such that one row of rollers and the compressible ring remain with one of the shafts while the other row of rollers remains with the other shaft. In both cases, all bearing components are prevented from falling out of position such that they return to their proper axial and radial position when the shafts come back together.

A thrust bearing includes cylindrical rollers arranged circumferentially in a bearing race with their rotational axes pointing radially to the central axis of the thrust bearing and each having a contact surface extending around and lengthwise of the cylindrical roller. The rollers includes at least pairs of radially adjacent first rollers with a radially inner first roller of each pair arranged with its rotational axis in alignment with the rotational axis of a radially outer first roller of the pair. The rollers also includes second rollers with at least one such second roller being arranged between adjacent pairs of first rollers in the circumferential direction, the at least one second roller being offset in the radial direction relative to the radially outer first rollers between which it is circumferentially arranged.
