摘要： A transmission arrangement is disclosed which comprises first and second variators (166, 169) each of which comprises an input race (150, 154) and an output race (152, 156). A plurality of rollers (276, 278) is arranged to run upon the input and output races to transfer drive from one to the other. The races are mounted for rotation about a common axis and the inclination of the first variator's rollers is variable independently of the inclination of the second variator's rollers, so that the two rollers are able to provide independently and continuously variable drive ratios. To provide traction between the rollers and races, a biasing device (216, 217) applies an axial force to one of the races, urging the rollers and races into engagement with each other. Each variator is provided with a shunt gear for providing forward, reverse and g eared neutral ratios, and to couple the variator input to the shunt gear a coupling member (160) passes through the outer variator races.

摘要： A neutral sensing assembly for a multiple shift rail (60B, 62B, 64B) shift bar housing assembly (70) is provided. The neutral sensing assembly utilizes a single two-position sensing (112, 114) and a relatively simply shaped neutral sensing bar (104) extending generally transverse to the axes (80, 82, 84) of the shift rails and interacting with neutral sensing notches (60C, 62C, 64C) for displacing the neutral sensing bar (FIG. 4 and 6) sufficiently to actuate the sensing upon axial displacement of any of the shift rails sufficient to cause the transmission (10) to be engaged in a not neutral condition.
