INTERNAL COMBUSTION ASSIST MEANS FOR A BICYCLE

摘要

The device has a junction of two power sources situated in front of a primary transmission (5) with different speeds. A torque limiter (6) is placed on kinematics of an electric motor (1) between the motor and the junction of power sources. The motor and the primary transmission are provided outside pedaling area. A secondary reduction gearbox case (3) serves as an air case for admission of the motor, where the case is fixed on a seat tube (4) by fitting using a screw. The tube filters residual vibrations. The case has a central pin for limiting vibrations from a sidewall of the case.
