    Abstract: A clutch release bearing comprises a maneuvering member operated on by a control member, usually a clutch release yoke. A drive member in direct or indirect axial bearing engagement with the maneuvering member, when operated on by the latter, operates on the clutch release device of a clutch. An axially acting spring washer of the Belleville spring type urges the drive member against the maneuvering member and retains the drive membering relative to the maneuvering member in the axial direction. This spring washer is able to turn inside out selectively so as to assume one or other of two separate stable configurations. One of these is a concave configuration and the other is a convex configuration. One configuration is an inoperative configuration and the other is an operative one. One peripheral edge of the spring washer bears axially on the drive member when it is in the operative configuration. On its other peripheral edge is a set of lugs through which it bears on the maneuvering member.

  • Patent number: 4778287
    Abstract: The invention concerns an annular multi-row bearing with shaped-wire races with an inner and an outer race, each of which constitutes part of the tracks for the rolling components, and with rolling components accommodated between them. The particular object is, in addition to others, to create a bearing that, although stable, is resilient enough when transverse forces occur to allow both races to twist in relation to each other within certain limits, avoiding stress.The invention attains this in that the contact or rolling surfaces between the races and the rolling components are provided with a contour that deviates from the rectilinear and mutually surrounds itself and in that these contact surfaces are shaped and/or positioned such that there is a four-point bearing in each track.This principle can be embodied with either ball bearings or roller bearings, whereby only three shaped wires are preferably employed. The angles of support range, depending on the type of bearing, between approximately 30.degree.

With this construction, the axial and radial deviations of the shaft can be minimized.

  • Patent number: 4492543
    Abstract: A rotation preventing/thrust bearing device for use in an orbiting member fluid displacement apparatus is disclosed. The rotation preventing/thrust bearing device includes a discrete fixed portion, a discrete orbital portion and bearing elements. The fixed portion includes a fixed race and fixed ring both of which are formed separately. The fixed race is placed in a groove in an inner surface of the housing and the fixed ring is attached to the housing. The orbital portion includes an orbital race and an orbital ring both of which are formed separately. The orbital race is placed in a groove in an end plate of the orbiting member and the orbital ring is attached to the end plate of the orbiting member. A plurality of pockets are formed axially in the rings toward the respective races. The pockets of the rings face one another in generally aligned pairs.

  • Patent number: 4482041
    Abstract: A clutch release bearing assembly is described in which a lubrication reservoir is provided between the bearing and the bearing carrier. The lubricant in this reservoir is communicable through a plurality of passageways in the bearing carrier to lubricate the reciprocable movement of the bearing carrier with respect to a guide member connected with the transmission. The bearing assembly is formed to provide a predetermined radial clearance between the bearing and bearing carrier which permits the bearing to shift radially with respect to the bearing carrier, so that the bearing may coaxially align itself with a clutch input shaft axis, said shifting being operative to transfer lubricant from the reservoir to the area between the bearing carrier and guide member.

  • Patent number: 4478325
    Abstract: A clutch throwout bearing assembly comprises a bearing, a carrier plate, and a carrier sleeve upon which the carrier plate and bearing are mounted. The mounting arrangement permits the bearing to be radially shifted, axially shifted, or tilted to adapt the plane of the bearing to the plane of the clutch fingers in situations involving misalignment of the bearing and clutch fingers due to tolerance build up between the clutch fingers and the bearing.
