The disengageable pulley device includes a pulley mounted on an inner transmission element, and a freewheel provided with a plurality of lock-up elements mounted between a sliding track of the pulley and a sliding track of the inner transmission element. The device is provided with a cage for the lock-up elements, with at least one annular friction element provided between the cage and the sliding track of the inner transmission element to use friction to connect the cage and the said inner element, and with at least one elastic return element positioned between at least one lock-up element and the cage, the elastic return element tending to keep the lock-up elements in contact with the sliding tracks when the freewheel is in the coupled position and in the uncoupled position.

The invention relates to a motor vehicle clutch release bearing device including a rolling bearing that forms a member for transmitting an axial force, having a rotating ring and a non-rotating ring, between which a rolling chamber for rolling elements is defined. The rotating ring provides a first radial portion intended to come into contact with an actuating member when a sufficient axial force is applied to the non-rotating ring by a member that is able to move in translation, and a second radial portion that is intended to bear against a spring, which exerts an axial force in the opposite direction to the axial force exerted by the member that is able to move in translation, dedicated to preloading the rolling bearing in an opposite direction to the actuating member.

The bearing provides an outer ring, an inner ring, at least one seal fixed to one of the rings and cooperating with the other ring, and at least one sealing flange fixed on the other ring. Flange is at least partly elastically deformable in the axial direction. Flange is axially mounted in contact against an outer lateral face of the seal. At least one local deformation is provided to the sealing flange to support elastically deformation of the flange. The sealing flange further provides at least one protrusion that axially extends beyond the local deformation.

This rolling bearing (1) comprises an inner ring (2), an outer ring (3), rolling members (5) placed in a rolling bearing chamber (4) arranged between the inner and outer rings, a bistable washer (7) capable of selectively taking one of two predetermined configurations, and an annular flange (8) partly delimiting the rolling bearing chamber (4) and mounted on a first ring (3; 2) of the inner and outer rings. The flange (8) extends radially from the first ring (3; 2) and is axially aligned with the second ring (2; 3).

A rolling-contact bearing device has a central axis and includes a non-rotating ring, a rotating ring having an axial guide portion providing a raceway for rolling elements, a reinforcement portion extending radially from the guide portion, and a mounting portion disposed generally against the reinforcement portion such that the two portions form a fold providing a double thickness of material, the reinforcement and mounting portions extending obliquely with respect to the central axis, and at least one row of rolling elements disposed between the non-rotating and rotating rings. A wear ring is mounted on the mounting portion of the rotating ring, contactable with the clutch mechanism diaphragm, and is dimensioned such that a force applied through the wear ring to the mounting portion of the rotating ring is oriented toward the guide portion.

A clutch release bearing device including an operating element, a rolling bearing equipped with a non-rotating race and a rotating race secured axially to the operating element, and an annular fixing ring provided with an axial portion mounted in the operating element and with an axially elastic portion bearing axially against the non-rotating race on the axially opposite side to the operating element, the fixing ring being able to hold the non-rotating race axially secured to the operating element while at the same time allowing radial movement.
摘要:
A piston bearing unit having an actuating piston which has a receiving region. The actuating piston is designed to actuate an element by way of a linear movement. The piston bearing unit also comprises a bearing having a first raceway and a second raceway, wherein the bearing is designed for mounting the actuating piston rotatably with respect to the element. The first raceway and the second raceway are at least partially accommodated in the receiving region.

The bearing provides an inner race, an outer race and a wear race that is made of synthetic material and fastened to one of the races. The wear race is overmoulded on at least one face of the race. The face includes at least one retention means that is covered with the synthetic material of the wear race and shaped to allow both the axial retention and the angular retention of the wear race relative to the race by shape complementarity with the wear race.
