Patent number: 11772740Abstract: 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.Type: GrantFiled: February 26, 2019Date of Patent: October 3, 2023Assignee: E2 DRIVES SAInventor: Arthur Deleval
