LOCK-UP DEVICE FOR FLUID COUPLING

摘要

A lock-up device for a fluid coupling suppresses vibration caused by coil springs. The lock-up device includes an input rotation member, an output rotation member, a plurality of sets of first elastic members, and a float member. The plurality of sets of first elastic members are compressed in a rotational direction by the relative rotation between the input rotation member and the output rotation member. The float member float member is configured to restrict movement of the plurality of sets of first elastic members in a radial direction.

1. A lock-up device for a fluid coupling for transmitting torque and absorbing and damping torsional vibration, the lock-up device for the fluid coupling comprising:
an input rotation member; an output rotation member; a plurality of sets of first elastic members compressed in a rotational direction by the relative rotation between the input rotation member and the output rotation member; and a float member configured to restrict movement of the first elastic members in a radial direction, the plurality of sets of the first elastic members being arranged adjacent to each other in a circumferential direction, the plurality of sets of the first elastic members being configured at a predetermined distance away from a center of rotation of the input rotation member, the plurality of sets of the first elastic members being rotatable relative to the float member, one set of the plurality of sets of the first elastic members including a plurality of spring members, the plurality of spring members being configured to be compressed in series continuously in the circumferential direction.
