Thermal assistance for bicycle

摘要

#CMT# #/CMT# 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. #CMT#USE : #/CMT# Device for assisting pedaling of a bicycle. #CMT#ADVANTAGE : #/CMT# The torque limiter permits to dissipate excess of kinetic energy so as to protect the transmission of the bicycle. The central pin of the case limits the vibrations from the sidewall of the case under the effect of pressure waves generated by the admission of motor while reducing mass of parts generating the vibrations. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a left perspective view of a bicycle. 1 : Electric motor 3 : Reduction gearbox case 4 : Seat tube 5 : Primary transmission 6 : Torque limiter.
