Abstract: A power transmission device has an interlocking member 9 moving a pressure member 5 from an inactive position to an active position. A release spring (m) applies an urging force, while allowing movements of the interlocking member 9 and the pressure member 5, until drive-side clutch plates 6 and driven-side clutch plates 7 reach an engaged state before the drive-side clutch plates 6 and the driven-side clutch plates 7 are pressed against each other. A clutch spring 11 is compressed in a process where the interlocking member 9 moves after the drive-side clutch plates 6 and the driven-side clutch plates 7 have reached the engaged state. The clutch spring applying a press-contact force between the drive-side clutch plates 6 and the driven-side clutch plates 7 while allowing movements of the interlocking member 9 and the pressure member 5. The set load of the clutch spring 11 is set to be smaller than the maximum load of the release spring (m).

Abstract: A power transmission device has a first pressure member (5a), a second pressure member (5b) and a back-torque transmitting cam. The first pressure member (5a) presses the drive-side clutch plates (6) and the driven-side clutch plates (7) against each other. The second pressure member (5b) releases a press-contact force between the drive-side clutch plates (6) and the driven-side clutch plates (7). The back-torque transmitting cam moves the second pressure member (5b) relative to the first pressure member (5a) to keep pressing the drive-side clutch plates (6) and the driven-side clutch plates (7) against each other when a rotational force is input to the clutch member (4), via the output shaft (3), in a process where the weight member (8) moves from the radially-outer position to the radially-inner position and the first pressure member (5a) moves to follow the interlocking member (9).

Abstract: A power transmission device has a first clutch member 4a coupled to an output member 3. A second clutch member 4b has a plurality of driven-side clutch plates 7. A back-torque transmitting cam presses the drive-side clutch plates 6 and the driven-side clutch plates 7 against each other by moving the second clutch member 4b when a rotational force is input to the first clutch member 4a. A cushioning member 12 is interposed between the first clutch member 4a and the second clutch member 4b. The cushioning member 12, by being compressed, applies an urging force while allowing movements of an interlocking member 9 and a pressure member 5 in a process where the interlocking member 9 moves and the pressure member 5 moves from the inactive position toward the active position.

Abstract: A power transmitting apparatus inputs or cuts off rotational power of an input member (1) to an output member (3) by press-contacting a plurality of driving-side clutch discs (6) and a plurality of driven-side clutch discs (7) with each other or releases them. A clutch housing (2) includes the driving-side clutch discs (6). A clutch member is (4) connected to the output member (3). A pressure member (5) press-contacts the discs (6) and discs (7) with each other or releases the press-contacting force between them. Application of a resisting force, for resisting relative rotation between the clutch member (4) and the pressure member (5), can be attained. A magnitude of the resisting force is set larger than a sticking torque between the discs (6) and discs (7).

Abstract: A method for forming an undercut portion of a formed article formed by plastically deforming a plate-shaped workpiece and a method for manufacturing a formed article having an undercut portion are provided. In these methods, the undercut portion is formed by press working performed using a punch and a die. These methods make the forming work more economical and more efficient. An outer portion of a plate member 91 (plate-shaped workpiece) located outward of a portion where an inwardly inclined portion 94 (undercut portion) is to be formed is bent by an angle determined such that an undercut surface 94a which constitutes the inwardly inclined portion 94 becomes parallel to the pressing direction of a punch 110. In addition, a peripheral wall portion 93 inclined by an angle corresponding to the bending angle is formed on the outer portion. The bent portion of the plate member 91 having the inclined peripheral wall portion 93 is bent back in the opposite direction so as to cause the inwardly inclined portion 94 to rise up from the surface of the plate member 91.

Abstract: A die for forming a press-formed component includes a piercing die, a piercing punch, and a support. The piercing die includes a tubular first forming portion for forming a boss portion and a second forming portion having a cutting edge and an inwardly extending portion. The second forming portion is adapted to perform pressing of a preform while cutting a portion thereof. A cutting edge which cooperates with the cutting edge of the second forming portion is formed at a distal end of the piercing punch. When forming a press-formed component, a projection end portion of a preform formed from a blank by drawing is cut and removed by the two cutting edges, and a preform boss portion is then pressed and swaged by the inwardly extending portion.

Abstract: A power transmitting apparatus for a vehicle mounted with a torque converter and an idle-stop mechanism can be configured to improve fuel economy without cancelling a fuel-cut-off during vehicle speed reduction and to reduce the manufacturing cost by eliminating an electrically-driven oil pump. A power transmitting apparatus can comprise a torque converter, a clutch mechanism, an oil pump, a continuously variable transmission, a clutch control device, an engine control device, and a flow control device. The flow control device can be configured to limit or prevent the supply of oil to the torque converter by the oil pump and to prioritize the supply of oil to the clutch mechanism and the continuously variable transmission when the vehicle speed is reduced below a predetermined value with fuel being cut off by the engine control device during vehicle speed reduction.
