CONTINUOUSLY VARIABLE TRANSMISSION

摘要

A chain (endless flexible member) is looped over an input pulley and an output pulley. Each of the input pulley and the output pulley includes a pair of a fixed sheave and a movable sheave. The fixed sheave and the movable sheave have tapered faces that are opposed to each other to define a V-shaped groove. A vibration damping plate (vibration damping member) is fixed to each fixed sheave, and is in contact with the outer peripheral face of the fixed sheave. When the fixed sheave vibrates, the vibrations are damped by the friction between the outer peripheral face of the fixed shave and the vibration damping plate.

1. A continuously variable transmission including two pulleys each having a rotary shaft and a pair of sheaves with tapered faces that are opposed to each other to define a V-shaped groove and an endless flexible member looped over the two pulleys, the continuously variable transmission varying a transmission ratio between the pulleys by varying a distance between the sheaves in each pair, the continuously variable transmission comprising:
a vibration damping member that is in contact, under pressure, with an outer peripheral face of the sheave to which the vibration damping member is fitted, wherein at least one of the sheaves is provided with the vibration damping member.
