Abstract
A torque converter 1 with a lock-up device 4 is provided to improve damping performance while suppressing an increase in the axial dimension. A torus 3 of the torque converter 1 includes an impeller 10, a turbine 11 and stator 12. The torus 3 has a shape such that a radial direction dimension is longer than an axial dimension thereof, and a longitudinal axis t1 is inclined away from a straight line P perpendicular to a rotational axis such that a radially outer portion of the longitudinal axis t1 is closer toward the engine than a radially inner portion thereof. The torsion springs 52 are located adjacent on the front cover side of a radially inner portion of the torus 3.
Claims20
A torque converter for transmitting torque from an engine to an input shaft of the transmission, comprising:
- a front cover being configured to receive torque from the engine;
- an impeller being fixed to said front cover defining a fluid chamber therewith;
- a turbine being located within said fluid chamber opposing said impeller;
- a stator being located between a radially inner portion of said impeller and a radially inner portion of said turbine to adjust a fluid flowing from said turbine to said impeller;
- a lock-up device being configured to transmit mechanically torque from said front cover to the input shaft and including an elastic member;
- and
- a torus being constituted by the impeller, the turbine and the stator, said torus having a radial dimension being longer than an axial dimension thereof, and a longitudinal axis thereof being inclined away from a straight line perpendicular to a rotational axis, a radially outer portion of the longitudinal axis being nearer to the engine than a radially inner portion thereof, and
- said elastic member being located adjacent on the front cover side of a radially inner portion of said torus.
