Abstract
An axially short, variable-ratio gear transmission suitable particularly for motorcycles has a first or input shaft, a second or output shaft, and a countershaft. First and second rotatable gears on the input shaft permanently mesh with respective first and second rotatable gears on the output and counter shafts. The first and second gears on the countershaft are permanently connected for joint rotation, a first coupling permits one of the two gears on the first shaft to be coupled to the first shaft, and a second coupling similarly may couple one of the gears on the second shaft to the latter.
Claims7
A variable ratio gear transmission comprising:
- a. a first shaft;
- b. a second shaft;
- c. first and second gear rotatable on each of said shafts in axially fixed respective positions,
- 1. each gear on one of said shafts permanently meshing with the corresponding gear on the other shaft;
- d. a countershaft;
- e. first and second gears mounted on said countershaft and permanently connected for joint rotation in permanent meshing engagement with said first and second gears on said first shaft respectively;
- f. first coupling means for coupling one of said first and second gears on said first shaft to said first shaft for joint rotation;
- and
- g. second coupling means for coupling to said second shaft one of said first and second gears on said second shaft.
