A clutch release bearing for a motor vehicle includes a thrust element having an axial axis, a guide element in the form of a tubular bushing that supports the thrust element, and a self-aligning sleeve including an annular body and a plurality of radial ribs each having a free end. The plurality of ribs extend towards the guide element from the annular body. The free ends of at least a first set of the plurality of radial ribs radially contact the cylindrical external surface of the bushing, and the bushing includes at least one opening in a cylindrical external surface of the bushing that is configured to receive one of the plurality of radial ribs.

Systems and methods for an electric drive axle are provided. In one example, the electric drive axle may include an electric motor-generator rotationally coupled to a gearbox having a one-way clutch mounted on an output shaft and operable in an engaged configuration and a disengaged configuration, where in the engaged configuration, the one-way clutch transfers rotational energy from the output shaft to an output gear rotationally coupled to a plurality of drive wheels. The gearbox further includes a mode adjustment mechanism including a lock ring rotationally coupled to the output shaft and configured to selectively engage an input gear and the one-way clutch in a plurality of operating modes.

A clutch release bearing for a motor vehicle includes a thrust element having an axial axis, a guide element supporting said thrust element, and a self-aligning sleeve including an annular body and a plurality of radial ribs extending towards the guide element from the body with a free end of each of the ribs radially contacting the guide element. The guide element includes angular retaining members for limiting angular movement of at least one radial rib of the plurality of radial ribs, which members may be integrally formed with the guide element or formed as separate elements attached to the guide element.

A clutch thrust bearing device including a rolling bearing, an axially movable piston having a radial plate, and a resilient biasing member. At least one between the inner and the outer peripheries of the radial plate of the axially movable piston is provided with a bearing sealing element of resilient material having at least one sealing lip in sliding contact with the rotatable ring of rolling bearing.

A sleeve for a clutch release/engagement thrust bearing device. The sleeve provides a body with a first axial bearing surface configured to work together with a translationally mobile control member, a second axial bearing surface configured to interact with a non-rotating ring of a bearing, and a central bore around a central axis configured to accept a cylindrical guide. The central bore of the sleeve provides a first series of guide portions with cylindrical surfaces, a second series of guide portions with cylindrical surfaces, which are axially at the opposite end to the first series. The guide portions of the first series are offset with respect to the guide portions of the second series in the circumferential direction, and an intermediate bore portion that is recessed with respect to the guide portions. The intermediate bore portion extending axially between the first and second series of the guide portions.

A self-aligning clutch release bearing having a rotating ring 114 and a static ring 112. Static ring 112 is located within a spherical cup 13, which incorporates an inner spherical surface 131, and the static ring 112 engages with the spherical cup 13 through the spherical surface 131. The spherical surface 131 has a radius whose center coincides with a center point 10 defined by intersection of the rotational axis 111 of the bearing and a plane defined by face of the rotating ring 114 that engages with fingers of the clutch. A spherical ring 14 incorporating a spherical end face 141 on its outer diameter is located within an inner diameter of the static ring 112, and engages with a spherical end face 113 on the inner diameter of the static ring. The two spherical end faces have about same radius with their centers coinciding with the center point 10.
