  • Patent number: 11772740
    Abstract: A power train of a pedal vehicle includes a crankset axle and a first output plate having a first axis of rotation. The first output plate is coupled with a transmission chain or belt so as to drive the rear wheel of the pedal vehicle. The coupling between the crankset axle and the transmission chain or belt extends through a planetary gear train which rotates about a second axis of rotation. The crankset axle is further coupled to the first output plate by a first free wheel (16) which is arranged to prevent the first output plate from rotating slower than the crankset axle when the crankset axle rotates in the normal pedalling direction.

  • Patent number: 10479447
    Abstract: Powertrain for a pedal vehicle Powertrain for a pedal vehicle comprising a first (20) and a second (4) motor as well as an planetary gearing (3) having a planet carrier (14, 114), a ring gear (12, 112) and a sun gear (13), which first motor (20) is connected to the planetary gearing (3), which powertrain also comprises a crank axle (11) to which the ring gear (12, 112) is connected to create a first input to the planetary gearing (3), the second motor (4) is geared to the crank axle (11), a control unit (6) being designed to regulate the first motor (20) according to an angular position setpoint, and the second motor (4) according to a current or torque setpoint.
