| 摘要 |
The invention concerns a transmission (1) comprising a gear assembly for transmitting a rotary motion from a driving shaft (2) to a driven shaft (3), with variable gear ratio, the two shafts (2 and 3) not being coaxial. This transmission consists in: a gear-wheel (4) axially split into two half-gear-wheels (5 and 6) one (5) axially mobile relative to the other (6) and also relative to one of the shafts (3) supporting them, the two half-gear-wheels (5 and 6) being fixed in rotation relative to this shaft (3); a plate (7), integral with the other shaft (2), comprising, on at least one of its surfaces, several gear teeth, concentric (8 to 11) with this shaft (2), co-operating with the gear-wheel (4); and means for axially displacing the two half-gear-wheels (5 and 6) to alter the geared concentric tooth (8 to 11), thereby shifting the gear ratio. The invention is preferably applicable to land vehicles. |
