A dual mass flywheel for a drivetrain of a motor vehicle includes a primary flywheel mass, a secondary flywheel mass and a coupling device. The coupling device includes at least two pivot levers associated with the secondary flywheel mass that interact with a control profile formed on the primary flywheel mass. The pivot levers are pretensioned against the control profile in a radial direction by an elastic element. A control segment of the elastic element is disposed radially inside the control profile.

The present invention relates to a dual mass flywheel for a drivetrain of a motor vehicle. The dual mass flywheel comprises a primary flywheel mass (12) and a secondary flywheel mass that can rotate relative to a rotary axis (r) of the dual mass flywheel, and that can be rotationally elastically coupled to each other by a coupling device (26). The coupling device (26) comprises at least two pivot levers (28) associated with one of the two flywheel masses (14, 12) and interacting with a control profile (36) associated with the other flywheel mass (12, 14). The pivot levers (28) are pretensioned by elastic elements (40) against the control profile (36) in a radial direction from the outside inward relative to the rotary axis (r). A central segment of each of the elastic elements (40) is disposed inside of the control profile (36) in the radial direction relative to the rotary axis (r).

A manual helical planetary transmission comprises a housing, a sun gear, a planet carrier with helical planetary gears and an axially displaceable ring gear which can be coupled to the housing or to the planet carrier. The transmission provides a compact and easy-to-produce solution for locking the gears. For this purpose, first saw-tooth coupling teeth are provided on both sides of the fronts of the ring gear and have a gently sloping first profile. Second saw-tooth coupling teeth provided on the housing and the planet carrier have a gently sloping profile and fit into the first coupling teeth. In the respective gear, the peripheral forces acting upon the ring gear force the gently sloping first profiles of the first coupling teeth against the gently sloping first profiles of the second coupling teeth on the housing or the planet carrier, thereby frictionally keeping the ring gear in the respective engaged position.

A drive axle for a light vehicle having a chain drive and a differential is provided, wherein the axle pinion gears (11, 12) are connected to their half-axles (6, 7) in one piece and to the vehicle via fixed bearings (8, 8′). One of the half-axles (6) is made as a tube which receives an inner shaft (13) in a journaled manner which is fixedly plugged in the other half-axle (7). The differential cage (22, 22′) is partly spherical and surrounds the balance pinion gears (20) and is fixedly connected to a chain sprocket (25). The differential cage comprises two symmetrical shells (22, 22′) between which the chain sprocket (25) is directly fastened to the balance pins.

A clutch for the shiftable connection of a primary part to a secondary part is a dog clutch, of which the dogs (12) and counterdogs (15) meshing one in the other in the engaged state are frontal dogs. In order to ensure a rapid opening of a generic clutch even under load, between the primary part (11) and the secondary part (8) an intermediate part (14) is provided which has the counterdogs (15) on its side facing the dogs (12) and, on its side facing away from the dogs (15), can be positively connected fixedly in terms of rotation via radially displaceable elements (17) to the secondary part (8) or to a part connected fixedly in terms of rotation to the latter, the position of these (17) being determined by the position of the shift sleeve (23). The radially displaceable sliding pieces (17) are guided in the intermediate part (14) and can be connected fixedly in terms of rotation via a deflecting coupling toothing (20, 21) to a bush (18) displaceable on the secondary part (8).
