Abstract
A gear assembly (10) for transmitting torque between an input rotatable member (12) and an output rotatable member e.g. differential unit (24) comprises an input gear (14) rotatable with the input member (12), an output gear (20) rotatable with the output member (24), and intermediate gears (16a, 16b, 16c, 16d) held simultaneously in mesh with the input gear (14) and output gear (20). Various arrangements are disclosed for sharing the transmitted torque evenly between the paths provided by gears (16a, 16b, 16c, 16d). The transmission may provide a reduction ratio and is connected to a low reduction ratio differential gearbox of small size and slim profile.
Claims12
An automotive transmission comprising a transfer gear train for transmitting torque between an input rotatable member and an output shaft rotating about substantially parallel axes, the transfer gear train comprising an input gear rotatable with the input member, an output gear rotatable with the output shaft, and a pair of intermediate gears each held simultaneously in mesh with the input gear and transmitting torque to the output gear to provide two power transmission paths;
- wherein the output shaft drives differential gearing arranged to distribute driving torque to a pair of ground engaging wheels.
