20140027235 | MECHANICAL SYSTEM WITH ONE-WAY CLUTCH AND ALTERNATOR COMPRISING SUCH A SYSTEM - 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. | 01-30-2014 |
20140034438 | MECHANICAL SYSTEM COMPRISING A ONE-WAY CLUTCH AND ALTERNATOR COMPRISING SUCH A SYSTEM - 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. | 02-06-2014 |
20140034439 | MECHANICAL SYSTEM COMPRISING A ONE-WAY CLUTCH AND ALTERNATOR COMPRISING SUCH A SYSTEM - 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. | 02-06-2014 |
20140083808 | MECHANICAL SYSTEM WITH ONE-WAY CLUTCH, AND ALTERNATOR COMPRISING SUCH A SYSTEM - This mechanical system with one-way clutch, such as a motor vehicle alternator pulley, provides an outer first ring and an inner second ring able to move relative to one another in rotation about a central axis and delimit between them, radially with respect to this central axis, an annular housing. A free-wheel mechanism having members arranged in the annular housing. At least one rolling bearing providing rollers arranged in the annular housing. The first and second rings are common to the free-wheel mechanism and to the rolling bearing. The members of the free-wheel mechanism are cams in contact with a first race formed by the first ring and a second race formed by the second ring. The first and second races are circular, centred on the axis of rotation and have no ramp. | 03-27-2014 |
20140364258 | SYSTEM FOR DRIVING A WATER PUMP AND MOUNTING METHOD - The present invention provides a system for driving a water pump. The system includes a driveshaft, a case containing the water pump, a bearing including a stationary ring that is stationary relative to the case and a rotating ring secured in rotation with the driveshaft. The system further includes a drive belt, at least one rolling path for the drive belt, the rolling path being secured in rotation with the rotating ring, and a flange transmitting the torque from the rotating ring to the drive shaft. The flange is made from plastic and is overmolded both on the rotating ring and on the driveshaft. The invention also relates to a mounting method for such a system. | 12-11-2014 |
