摘要： Disclosed is a bicycle transmission ratio changing system comprising bicycle transmission, and a control unit configured to change the bicycle transmission according to an shift sequence. The shift sequence includes a synchronous shift step of synchronously changing the transmission ratio of a first transmission and the transmission ratio of a second transmission; and a non-synchronous shift step of selectively changing either the transmission ratio of the first transmission or the transmission ratio of the second transmission. The shift sequence includes at least the lower of Nor M−1 synchronous shift steps, wherein N corresponds to the number of different transmission ratios of the first transmission and M corresponds to the number of different transmission ratios of the second transmission.

摘要： A torque support assembly, for supporting a torque of a hollow shaft onto a frame of a bicycle, comprising a cam comprising a cam hole for receiving therein a distal end of the shaft, wherein the cam hole and the shaft are interlockingly shaped for rotationally locking the cam and shaft with respect to each other, an adapter interface comprising a first face defining a seat for the cam, and an adapter interface through hole which extends from the seat on the first face and is coaxial with the cam hole for allowing a thru-axle to extend there through. The adapter interface comprises an upstanding wall, extending outward from the first face, defining an inner support surface of the seat on which the cam is supported against rotation.

摘要： Disclosed is a transmission system for a vehicle, particularly for a bicycle. The system comprises an input and an output, and a first transmission and a second transmission between the input and the output, wherein the first transmission and the second transmission are connected in series. The first transmission is selectively operable according to a first transmission ratio or a second transmission ratio, and has a first load-shifting clutch for switching the first transmission from the first transmission ratio to the second transmission ratio and/or vice versa. The second transmission is selectively operable according to a third transmission ratio or a fourth transmission ratio, and has a second load-shifting clutch for switching the second transmission from the third transmission ratio to the fourth transmission ratio and/or vice versa.

摘要： The disclosure relates to a continuously variable transmission (CVT) unit. The CVT unit comprises a first drive element that is rotatable about a first axis and a second drive element that is rotatable about a second axis parallel to the first axis, wherein the first drive element and the second drive element are movable relative to each other in a direction transverse to the first and second axis. The CVT unit further comprises first coupling elements provided at a constant first radius from the first axis and at a variable second radius from the second axis, for transferring torque between the first drive element and the second drive element.
