摘要: A gear reduction mechanism, particularly for use in an offset final drive unit for vehicular applications, has an input gear meshing directly with the output gear and two additional gear trains between the input and output gears. Three separate load paths therefore exist for the transmission of torque from the input gear to the output gear which means that the face widths of all the gears can be substantially reduced in comparison with a conventional single-mesh arrangement and the overall mechanism can therefore be of reduced width.

摘要: A gear change mechanism coupling a pair of shafts (2) and (9) employs a planetary gear set comprising a sun gear (10) fast with shaft (2), planet gears (12) in a planet carrier (15), and an annulus or ring gear (17), the latter being fixed. A selector hub (19) slidable on shaft (9) has sets of radially spaced dogs (22) and (24) to engage with corresponding dogs (29) and (34) on the planet carrier and sun gear respectively, so as to couple the shafts (2) and (9) at two different ratios depending on the axial position of the selector hub. This results in a more axially compact package than conventional dog clutch gear changers. In an alternative embodiment a reversing mechanism is provided by fixing the planet carrier and engaging the selector hub with the sun gear or annulus depending on its axial position.

摘要: A Transmission A transmission (10) comprising a plurality of shafts (12,14,16) each carrying a plurality of drive members(18a, 18b, 18c, 20a, 20b, 20b 2, 20c, 22a, 22b, 22b 2, 22c), the drive members on each said shaft arranged to operatively cooperate with those carried by at least one other said shaft for transferring load between a torque input (13) and a torque output (15) of the transmission in use, the transmission being configured such that respective resultant gear ratios between the torque input and the torque output can be selected in use from each of a plurality of groups thereof by changing a load path L1 between the torque input and the torque output, wherein each said group of selectable resultant gear ratios has a load path feature for transferring load between a pair of the shafts which is common to the selectable resultant gear ratios within that group.

摘要: Some embodiments are directed to a gearbox including first and second rotational members, the first rotational member having a shaft portion extending away from the gearbox, the first rotational member carrying one or more projections, the second rotational member carrying one or more complementary projections, the projections carried by the first rotational member being configured to be drivingly engaged with the complementary projections carried by the second rotational member to transmit torque in a first torque connection but not in a torque connection that is opposed to the first torque connection. The gearbox further includes a one way clutch adapted such that the first and second rotational members can be drivingly engaged to transmit torque in a second torque connection, wherein the second torque connection is opposed to the first torque connection.
