Title:
DYNAMIC VIBRATION ABSORBER
Document Type and Number:
WIPO Patent Application WO/2016/167025
Kind Code:
A1
Abstract:
Provide is a torque converter with which it is possible to reliably damp fluctuations in torque and to impart flexibility to the design and placement of a dynamic vibration absorber. A torque converter (1) is provided with: a front cover (2), a lock-up device (7), and a dynamic vibration absorber (8). The lock-up device (7) has a piston (24) and a damper unit (30). The piston (24) allows or releases the transmission of torque from the front cover (2). When the transmission of torque is allowed by the piston (24), the damper unit (30) damps fluctuations in torque from the front cover (2). The dynamic vibration absorber (8) is directly coupled to the lock-up device (7). The dynamic vibration absorber (8) damps fluctuations in torque from the lock-up device (7) and outputs the torque from the lock-up device (7) to the transmission.
