Abstract
Assembly (57) for a speed reducer of a rotary electric machine, comprising: a ring gear (46) secured to a transverse wall (58); a base plate (60) to be securely and rotatably mounted relative to a mounting (16) of the machine; an axially acting resilient means, such as an axially acting resilient disc (64); and an added hub (68) on which the transverse wall (58) of the ring gear (46), the base plate (60), and the resilient means (64) are mounted. The hub (68) has at least one first shoulder (71) for supporting the axially acting resilient means (64), and at least one second shoulder (72) for supporting the transverse wall (58) of the ring gear (46). The assembly also relates to a starter, particularly for a motor vehicle.
Claims21
An assembly (57) for a speed reducer of a rotary electrical machine (11), comprising:
- a toothed ring (46) integral with a transverse wall (58);
- a base plate (60) mounted integrally non-rotatably to a support (16) of the machine;
- a resilient member with axial action (64);
- and
- an added-on hub (68) supporting the transverse wall (58) of the toothed ring (46), the base plate (60) and the resilient member (64);
- the added-on hub (68) including at least one first shoulder (71) for support of the resilient member (64) with axial action and at least one second shoulder (72) for support of the transverse wall (58) of the toothed ring (46);
- the base plate (60) axially moveable relative to the transverse wall (58) and rotatably mounted to the added-on hub (68) between the transverse wall (58) and the resilient member (64);
- the transverse wall (58) non-rotatably mounted to the added-on hub (68).
A starter (10) for a motor vehicle, comprising:
- an electrical machine (11) comprising an output shaft (24);
- an epicycloidal train comprising a planet wheel (49) which is connected in rotation to the output shaft (24) of the electrical (11) machine;
- a speed reducer assembly (57) comprising:
- a toothed ring (46) integral with a transverse wall (58);
- a base plate (60) mounted integrally non-rotatably to a support (16) of the machine;
- a resilient member with axial action;
- and
- an added-on hub (68) supporting the transverse wall (58) of the toothed ring (46), the base plate (60) and the resilient member (64);
- the added-on hub (68) including at least one first shoulder (71) for support of the resilient member (64) with axial action and at least one second shoulder (72) for support of the transverse wall (58) of the toothed ring (46);
- and
- a satellite-holder (47) engaging firstly with the planet wheel (49), and secondly with the toothed ring (46) of the speed reducer assembly, the satellite-holder (47) being non-rotatably connected with an output shaft (43) of the starter which supports a drive pinion (50) designed to be engaged with the teeth of the drive ring of a thermal engine of the vehicle;
- the base plate (60) axially moveable relative to the transverse wall (58) and rotatably mounted to the added-on hub (68) between the transverse wall (58) and the resilient member (64);
- the transverse wall (58) non-rotatably mounted to the added-on hub (68).
