摘要： A continuously variable reversible transmission including an input shaft (2), a housing (1), an input arm (4), first and second CVT shafts (5.6), a fixed input wheel (35), a ratio selector mechanism, an overall output wheel (36) and an output shaft (24). The input arm (4) is fixed to the input shaft (2) and extends substantially perpendicular to the input shaft. At each end of the input arm, a first (5) and second (6) CVT shaft is rotatably mounted, with the axes of the CVT shafts extending parallel to the input shaft. The fixed input wheel (35) may be aligned with the axis of the input shaft. The first CVT shaft (5) is coupled with the fixed input wheel (35), the second CVT shaft (6) is coupled with the first CVT shaft (5) and the output wheel (36) which is fixed to the output shaft (24) is coupled with the second CVT shaft. The first and second CVT shafts may orbit around the axis of the input shaft, such that changing the ratio of at least one of the couplings produces a variation of the speed of the output shaft from forwards, through zero to reverse.

摘要： A multi-bit tool (1) including a housing (2) and a drive input shaft (3). The housing incorporates at least two storage recesses (5) accessible from outside the housing. The housing may include a first (6) and a second (7) socket, each axially aligned with the drive input shaft, the first socket being smaller than the second socket and positioned intermediate the second socket and the drive input shaft such that tool bits (4) driven by the first socket pass through the second socket to drivably engage with the first socket. It is preferable that the storage recesses communicate with a central bore to permit the active bit to be internally interchanged. To this end the housing may further incorporate a bore axially aligned with the drive input shaft and the first and second sockets. The tool may further include a sleeve (20) and bolt (21) assembly operable between a bit loading position and a working position, the bolt having a claw (35) to engage a waisted portion (15) of the tool bit, a flange portion (41) and a drive input portion being the drive input shaft (3). In use, the tool drives bits through the drive input shaft which receives drive input to the bolt part of the tool, the flange portion of the bolt driving the housing to thereby transmit the drive input to the first and second sockets of the housing.
