摘要： PROBLEM TO BE SOLVED: To improve continuous responsiveness of a lock-up clutch in a simple constitution in a hydraulic power transmission.
SOLUTION: In the hydraulic power transmission, a clutch chamber 22 defined between a side cover 5 connected to a pump impeller 2 and the outer surface of a turbine runner 3 is partitioned to an inner oil chamber 23 and an outer oil chamber 24 by a clutch piston 19 connected to the turbine runner 3. Between the turbine runner 3 and the clutch piston 19, an elastic partition member 25 is disposed. The elastic partition member 25 exerts a resilient force in a direction for separating the turbine runner 3 from the clutch piston 19 while partitioning the inner oil chamber 23 to a primary inner oil chamber 23a radially inside and a secondary inner oil chamber 23b radially outside when the clutch piston 19 occupies a non-operation position. When a lock-up controlling means 42 is operated to press the clutch piston 19 in an operation direction, temperatures of the primary inner oil chamber 23a and the secondary inner oil chamber 23b are increased in this order with respect to the outer oil chamber 24.

摘要： PROBLEM TO BE SOLVED: To make a coned disc spring to energize the clutch piston of a lockup clutch in a clutch ON direction display original spring characteristics, in a hydraulic power transmission and to improve its durability. SOLUTION: In the hydraulic power in which transmission a clutch piston 19 of an lockup clutch L is disposed between a side cover 5 situated in a line to a pump impeller 2 and a turbine runner, the coned disc spring 33 to energize the piston hub in a clutch-on direction is mounted in a free deformation posture on the piston hub 19a of the clutch piston 19 slidably supported at a turbine hub 3a. A regulation means 45 to prevent excessive deformation of the coned disc spring 33 by regulating a moving backward amount to a specified value when the clutch piston 19 is moved backward in a clutch-off direction is situated between the clutch piston 19 and the turbine runner 3.

摘要： PROBLEM TO BE SOLVED: To provide a friction plate for a wet clutch capable of stabilizing a friction characteristic at a connection transition time of the clutch, and reducing a dragging phenomenon due to viscous resistance of oil at the clutch-off time. SOLUTION: In this friction plate for a wet clutch, a large number of oil grooves 22 communicating inner and outer peripheral edges of a friction material 21 are formed to the friction material 21 coupled with one side face or both side faces of a core plate 20. When a friction plate 15 rotates, a plurality of oil grooves 22 having a discharge angle β for discharging the oil from the inner peripheral side to the outer peripheral side of the friction plate 15, and a plurality of oil grooves 22 having a flow-in angle α or taking the oil from the outer peripheral side to the inner peripheral side of the friction plate 15 are alternatively arranged at approximately equal intervals.

摘要： A fluid transmitting system includes a lock-up clutch (L) whose clutch piston (19) is disposed between a side cover connected to a pump impeller (6) and a turbine runner (3). A Belleville spring (33) for biasing the clutch piston to a clutch turning-on direction is mounted to a piston hub of the clutch piston slidably carried on a turbine hub (3a) so that the deformation attitude thereof is changed freely. A limiting means (45) is provided between the clutch piston and the turbine runner for limiting the amount of retraction of the clutch piston to a constant value thereby preventing excessive deformation of the Belleville spring, when the clutch piston is retracted in a clutch turning-off direction. Thus, the Belleville spring for biasing the clutch piston of the lock-up clutch in the clutch turning-on direction can exhibit an intrinsic spring characteristic, and moreover the durability of the Belleville spring can be enhanced.
