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

Publication number: 20220274670Abstract: The invention relates to a propulsion system (1) for a pedal vehicle. The propulsion system (1) comprises a power unit (1) allowing the power originating from a bottom-bracket axle (2) to be combined with the power from two motors (40, 50), a first deformable transmission element (23) allowing the transmission of power to the rear wheel (73) and a casing assembly (19) enclosing particularly the first deformable transmission element (23) and the power unit (1), with the exception of part of the bottom-bracket axle (2).Type: ApplicationFiled: August 12, 2020Publication date: September 1, 2022Applicant: E2 DRIVESInventor: Arthur DELEVAL

Patent number: 11383791Abstract: A powertrain for a pedal vehicle includes a crank axle and an output sprocket rotating around a first rotation axis. The coupling between the crank axle and the output sprocket goes through an epicyclic gear system that includes a ring gear, a planet carrier, and a sun gear (13) which rotate around a second rotation axis that is spatially offset from the first rotation axis.Type: GrantFiled: August 30, 2018Date of Patent: July 12, 2022Assignee: E2 DRIVESInventors: Arthur Deleval, Simon Godfrind
