Abstract
A pedaling assistance device for a light vehicle, in particular a bicycle, equipped with pedals and a ratio-changing transmission, this device comprising a heat engine equipped with a reducing gear mechanically coupled with an element receiving muscular pedaling power from a user of the light vehicle, the mechanical coupling being effected upstream of said ratio-changing transmission so that the heat engine benefits from said changes of ratio, wherein the assistance device comprises a torque limiter, placed on the kinematics of the reducing gear of the heat engine between said heat engine and the mechanical coupling.
Claims16
A pedaling assistance device for a light vehicle equipped with pedals and a transmission, this assistance device comprising a heat engine equipped with a reducing gear mechanically coupled with an element receiving muscular pedaling power from a user of the light vehicle, wherein the assistance device comprises a jacket encapsulating the heat engine,
- wherein the jacket comprises a packing made of sound barrier material.
A pedaling assistance device for a light vehicle equipped with pedals and a transmission, this assistance device comprising a heat engine equipped with a reducing gear mechanically coupled with an element receiving muscular pedaling power from a user of the light vehicle, wherein the assistance device comprises a jacket encapsulating the heat engine,
- wherein the jacket comprises an inner wall and an outer wall between which one or more tanks are formed that can contain a liquid.
A pedaling assistance device for a light vehicle equipped with pedals and a transmission, this assistance device comprising a heat engine equipped with a reducing gear mechanically coupled with an element receiving muscular pedaling power from a user of the light vehicle, wherein the assistance device comprises a jacket encapsulating the heat engine,
- wherein the engine has liquid cooling and in that two ducts pass through the jacket to allow the liquid to enter and leave the jacket, a heat exchanger connected to these ducts being arranged outside the jacket.
