The present invention relates to a mechanical system with a one-way clutch, for example a pulley for a motor vehicle alternator, comprising a first element and a second element which are able to move one with respect to the other in rotation about a central axis and delimit an annular housing radially to the central axis, a one-way clutch device arranged in the annular housing, and at least one rolling bearing arranged in the annular housing. The mechanical system is characterized in that the rolling bearing comprises at least one pressed ring distinct from the constituent elements of the one-way clutch device. The invention also relates to an alternator comprising such a mechanical system configured as a pulley with a one-way clutch.

The present invention relates to a mechanical system with a one-way clutch, for example a pulley for a motor vehicle alternator, comprising a first element and a second element which are able to move one with respect to the other in rotation about a central axis and delimit an annular housing radially to the central axis, a one-way clutch device arranged in the annular housing, and at least one rolling bearing arranged in the annular housing. The mechanical system is characterized in that the rolling bearing is an angular-contact bearing and comprises at least one pressed ring comprising means of attachment of the rolling bearing to the first element or the second element. The invention also relates to an alternator comprising such a mechanical system configured as a pulley with a one-way clutch.

The present invention concerns a suspension thrust bearing device adapted to receive a shock absorber piston rod along a main axis (X), the device including a single bearing forming an axial thrust bearing and including an inner race, an outer race and rolling members disposed between the inner race and the outer race, and at least one intermediate member adapted to transmit to the inner race essentially axial forces exerted on the device by a suspension spring. One of the inner race and the intermediate member extend(s) radially beyond the outer race in the direction of the main axis (X), forming a bearing surface for fixing and centering the shock absorber piston rod relative to the device. The invention also concerns a motor vehicle McPherson strut including a shock absorber and a suspension thrust bearing device as referred to above.
