摘要:
Turbocharger comprising a shaft (3), a housing (2), a turbine wheel (6) and a compressor wheel (5) mounted onto the shaft (3), at least one rolling bearing (4) located between the shaft (3) and the housing (2) and comprising an inner ring (8), an outer ring (9) and at least one row of rolling elements (10a, 10b) between raceways provided on the rings (8, 9). The turbocharger (1) comprises two insulation means (22, 23) radially located between the inner ring (8) and the shaft (3), so as to thermally isolate the inner ring (8) from the shaft (3).
摘要:
This torque transmission mechanism (A), for a starter for an internal combustion engine, is adapted to transmit a starting torque from a starter motor to a crankshaft (4). The torque transmission mechanism (A) comprises a ring gear (2) that transmits the starting torque and a one-way clutch (8) disposed between the ring gear (2) and the crankshaft (4), this ring gear (2) comprising a gear side portion (22) to which the starting torque is transmitted from the starter motor via gear mesh, and a flange (24) extending between the gear side portion (22) and an inner ring (82) of the one-way clutch (8). The flange (24) comprises an inner section (240) which forms the inner ring (82) of the one-way clutch (8) and an outer section (242) fixed to the inner section (240) and on which the gear side portion (22) is fixed. The inner and outer sections (240, 242) of the flange (24) are fixed together by a mechanical assembly other than welding.

This torque transmission mechanism (A) for an internal combustion engine, adapted to transmit a starting torque from a starter motor to a crankshaft (4) of the internal combustion engine, comprises a ring gear (2) that transmits the starting torque and a one-way clutch (8) disposed between the ring gear (2) and the crankshaft (4), the one-way clutch (8) including an inner ring (7), an outer ring (84) and sprags (86) adapted to cooperate with the inner (7) and outer (84) rings to selectively transmit torque between the inner (7) and outer (84) rings or allow relative rotation between the inner (7) and outer (84) rings. The one-way clutch (8) comprises a single cage (88) in which the sprags (86) are mounted, and the sprags (86) are adapted to lose contact with the inner ring (7) when the inner ring (7) rotates (R2) at a rotation speed inferior to the rotation speed of the outer ring (84).

This torque transmission mechanism (A) for an internal combustion engine, adapted to transmit a starting torque from a starter motor to a crankshaft (4) of the internal combustion engine, comprises a ring gear (2) that transmits the starting torque, a one-way clutch (8) disposed between the ring gear (2) and the crankshaft (4), a bearing (6) including a first ring (7) coupled in rotation with the gear ring (2) and a second ring (62) coupled in rotation with the crankshaft (4) and a front plate (10) for coupling in rotation the crankshaft (4) with the one-way clutch (8). The front plate (10) is coupled in rotation with the crankshaft (4) via the second ring (62) of the bearing (6), by welding along a direction (F1) parallel to a central axis (X-X') of the second ring (62) of the bearing (6).
摘要:
This torque transmission mechanism (A) for an internal combustion engine is adapted to transmit a starting torque from a starter motor to a crankshaft (4) of the internal combustion engine and comprises a ring gear (2) that transmits the starting torque and a one-way clutch (8) disposed between the ring gear (2) and the crankshaft (4). Rotation of the ring gear (2) with respect to the crankshaft (4) is allowed by a sliding contact between at least two surfaces (60, 820, 62, 122).
