Abstract:
PCT No. PCT/AU94/00445 Sec. 371 Date May 5, 1995 Sec. 102(e) Date May 5, 1995 PCT Filed Aug. 5, 1994 PCT Pub. No. WO95/06829 PCT Pub. Date Mar. 9, 1995A transmission is disclosed which has an input power supply (53, 34, 328) and a plurality of secondary members which are driven by the input power supply. The secondary members can be in the form of pawls (344, 361) or rack and pinion arrangements (54, 56). An infinitely variable gear ratio adjustment mechanism which can adjust the gear ratio between a maximum and minimum ratio is provided and generally comprises a fixed inner eccentric (318) and a movable outer eccentric (320). The outer eccentric (320) can be moved to adjust the eccentricity of the eccentrics to thereby set the gear ratio to any ratio between the minimum and maximum. The pawls (344, 361) or racks and pinions (54, 56) are arranged on the eccentrics (318, 320) and are driven by the input for only part of each revolution of the input other than when the gear ratio is set as 1:1. A mechanism for ensuring that the load applied to the secondary members is distributed between at least two of the secondary members at any one time is provided and comprises a lever arrangement (106), a floating ring arrangement (76) or a resilient biasing rubber ring (380, 382).
