Abstract
A continuously variable transmission for a vehicle includes first and second continuously variable shift parts. A torsional damper for absorbing torsional vibration caused by a change in engine torque is connected to an output shaft of an engine. A forward/reverse control mechanism for controlling forward and reverse drive of the vehicle is connected to said damping means. The first continuously variable part is connected to the forward/reverse control means through a first power transmission member. The second continuously variable shift part transmits shifted rotating force to a final reduction gear system.
Claims17
A continuously variable transmission for a vehicle, comprising:
- damping means for absorbing torsional vibration caused by a change in engine torque, said damping means being connected to an output shaft of an engine;
- forward/reverse control means for controlling forward and reverse drive of the vehicle, said forward/reverse control means being connected to said damping means;
- first shift means for continuously variably shifting rotating force transmitted from the forward/reverse control means, said first shift means being connected to the forward/reverse control means through a first power transmission member;
- and
- second shift means for continuously variably shift rotating force, which is continuously variable shifted in said first shift means, and transmitting shifted rotating force to a final reduction gear system, said second shift means being connected to the first shift means through a second power transmission member.
