Abstract
Clutch bearing device comprising an actuating element intended to be mounted on an operating element 2. The actuating element comprises a rolling bearing 1 provided with a rotating race 15 and with a non-rotating race 9, the said bearing 1 being able to be displaced radially with respect to the operating element 2 to self-align with the clutch diaphragm, the non-rotating race 9 comprising an inwardly-directed radial portion 13. The device comprises a means of axially securing the actuating element to the operating element 2. The device comprises a self-alignment member 21 centered on the non-rotating race 9 and provided with axially elastic elements 23.
Claims14
Clutch bearing device comprising:
- an actuating element intended to be mounted on an operating element, the actuating element comprising a rolling bearing provided with a rotating race and a non-rotating race, said bearing being able to be displaced radially with respect to the operating element to self-align with a clutch diaphragm, the non-rotating race comprising an inwardly-directed radial portion,
- a means of axially securing the actuating element to the operating element, and
- a self-alignment member centred on the non-rotating raced and provided with axially elastic elements, so that said self-alignment member exerts, on the means of axial securing and on the non-rotating race, axial forces in opposite directions and keeps the non-rotating race in permanent axial contact with a radial bearing surface of the operating element.
Actuating element intended to be mounted on an operating element to form a clutch bearing device, the actuating member comprising:
- a rolling bearing provided with a rotating race, a non-rotating race and a row of rolling elements, said rolling bearing being designed to be able to be displaced radially with respect to the operating element so as to self-align with a diaphragm of the clutch, the non-rotating race comprising an inwardly-directed radial portion, and
- a self-alignment member centred on the non-rotating raced and provided with axially elastic elements, coming from a radial portion of said self-alignment member, at least some of the elastic elements when in a free state projecting axially with respect to said radial portion.
