| 摘要 |
The invention relates to a drive system for a pedal-operated vehicle (1), comprising a drive motor (3), by means of which a driving force for the vehicle (1) can be produced, pedals (10, 11) on pedal arms (7, 8), a bottom bracket shaft (12), to which the pedal arms (7, 8) are fastened, and a drive mechanism for transmitting driving energy from the bottom bracket shaft (12) to a wheel (9) of the vehicle, wherein there is play in a transmission path of driving energy between a pedal arm (7, 8) and a drive wheel (13) of the drive mechanism, which drive wheel co-rotates with the bottom bracket shaft (12), wherein the drive system comprises a restoring device (17), by means of which the parts having play, the bottom bracket shaft (12) and the drive wheel (13), can be brought into a resting position in relation to each other within the play of the parts having play at or below a resting pedal force, in which resting position the parts having play at least approximately assume a specified relative position in relation to each other, wherein the parts having play can be removed from the resting position within the play against the effect of the restoring device (17) by means of a pedal force above the resting pedal force, and wherein information about whether the parts having play are in the resting position can be provided in the form of one or more electrical signals. |
