Lock-up apparatus in torque converter |
摘要 |
A lock-up apparatus in a torque converter includes a first oil chamber (25) and a second oil chamber (26) delimited by a lock-up piston (21), a first oil line system (A) communicating with the first oil chamber (25), and a second oil line system (B) communicating with the second oil chamber (26). An orifice (36) and an oil line (37) for directly communicating the first oil line system (A) and the second oil chamber (26) are provided in an output shaft (20) and a turbine hub (19), respectively. Accordingly, the first oil chamber (25) and the second oil chamber (26) are not directly communicated. As a result, not only is shock produced at release from the locked up state mitigated by the orifice (36) and oil line (37), but it is also possible to reliably prevent a decline in transmission torque capacity in the lock-up ON state.
