摘要： A system for automatically changing the transmission ratio of a bicycle includes a rotation frequency sensor of the pedals of the bicycle, that is the pedaling cadence, an acceleration sensor fixed to the frame of the bicycle which indicates the angle of inclination in the direction of advancement of the bicycle with respect to a horizontal plane, a sensor or torque estimator functionally mounted on the bicycle to provide a torque signal representative of a resistant torque acting on the pedals of the bicycle, a non-volatile memory which contains a table for consulting reference values of the rotation frequency of the pedals (pedaling cadence) in function of values of the angle of inclination of the advancement direction, as well as a control unit in communication with the frequency sensor, the torque sensor or estimator and the acceleration sensor and with the non-volatile memory, configured to: read from the memory a reference value of the rotation frequency of the pedals using as input the angle of inclination detected by the sensor, compare the effective frequency of rotation of the pedals with the reference value read from the memory, and automatically increase or reduce the ratio of transmission of the bicycle according to said comparison and to said value of resistant torque on the pedals of the bicycle, so as to adjust the pedaling cadence required to the cyclist with the reference value of the rotation frequency read by the non-volatile memory and of the resistant torque value on the bicycle pedals. A method for automatically changing a transmission of a bicycle is also disclosed.

摘要： A gearbox may include a drive spindle and several interconnected gear clusters arranged in a housing. A first of the gear clusters is coaxially fastened to the spindle, and has an outboard gear and an inboard gear. The first gear cluster drives a belt or chain to operate one or more of the other gear clusters, and the inboard gear is physically divided into a plurality of segments. A shifting system for the gearbox includes an actuator configured to urge the segments of the inboard gear of the first gear cluster into and out of the plane of the belt or chain via a toggle and slider mechanism, such that a gear ratio of the gearbox is changeable without displacing the belt or chain out of the plane.

摘要： The present invention relates to a pedaling-assisting transmission, and particularly, to an apparatus which senses stepping pressure being applied onto a pedal by a rider, and actively controls a motor driving force for driving a motor in accordance with the sensed stepping pressure. The apparatus comprises: a fixed shaft (100) fixed on a vehicle frame; a hub shell (200) rotatably supported at an outer surface of the fixed shaft (100) to output a follower force; an electromotive-force-driven unit (300) driven by the rotation of a motor (310); a manual-force-driven unit (400) which receives, as an input, a driving force produced by the pedaling of the rider, and which is driven by the received driving force; a selective output unit (500) arranged among the electromotive-force-driven unit (300), the manual-force-driven unit (400) and the hub shell (200) so as to selectively transmit, to the hub shell (200), an output from either the electromotive-force-driven unit (300) and the manual-force-driven unit (400), which rotates at a speed higher than that of the other; a torque sensor (600) which senses driving forces being applied from an external source to the manual-force-driven unit (400); and a control unit (not shown) which controls the rotating speed of the motor (310) in accordance with the driving forces sensed by the torque sensor (600). The apparatus of the present invention not only enables the rider to easily accelerate the vehicle, should the rider so desire, through the motor by pedaling without an additional operation, but also enables multi-stage gear-shifting to be autonomously performed in the apparatus by means of a multi-stage planetary gear, thereby achieving suitable torque and speed in accordance with travel conditions.
