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).
摘要:
This method is for manufacturing a torque transmission mechanism (A) between a starter motor and a crankshaft (4) of an internal combustion engine, comprising a one-way clutch (8) including an outer ring (84) fast in rotation with the crankshaft (4) via a front plate (10). This method comprises the following steps: a) forging the outer ring (84) out of carburizing steel, b) carburizing the outer ring (84), c) tempering the outer ring (84), d) grinding an inner surface (842) of the outer ring (84), e) manufacturing the front plate (10) out of standard low equivalent carbon content steel, f) assembling the front plate (10) and the outer ring (84).

Dispositif de roulement de butée de suspension 3, comprenant une première bague 7, une deuxième bague 6, une rangée d'éléments roulants 8 disposés entre les deux bagues, un capot 19 dans lequel est disposée la première bague 7, et au moins une garniture d'étanchéité 27 fixée sur le capot 19 et apte à coopérer avec une surface respectivement non tournante ou tournante, la garniture d'étanchéité 27 comprenant une portion de liaison 30 avec le capot 19 et une lèvre d'étanchéité 28, la garniture d'étanchéité 27 étant fixée au capot 19 par une pluralité de protubérances 31 issues de la portion de liaison 30 et venant en saillie, au moins partiellement, dans au moins un logement 32 du capot 19 avec lesquels lesdites protubérances 31 coopèrent pour assurer la liaison axiale entre le capot 19 et la garniture d'étanchéité 27.
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.
