摘要： Methods and apparatuses can be used to adjust the torque transfer capacity and improve the overall performance and longevity of a clutch assembly. Through the use of various improved clutch components disclosed herein, it is possible to: (1) increase clutch apply forces through an increase in the fluid pressure apply surface area, or piston reaction area, of a clutch piston, thereby increasing frictional forces generated within a clutch pack for transferring input torque from a drive shaft to a driven shaft; (2) improve clutch plate contact conditions through a more rigid clutch pressure plate configuration, thereby reducing clutch pack/plate distortion and supporting structure deformation and/or wear that can otherwise lead to excessive heat generation and overall clutch performance degradation and/or failure; and/or (3) improve the clutch assembly's ability to dissipate and/or tolerate heat generated through clutch plate friction by means of an improved clutch pack configuration.

摘要： A clutch device includes a pressure plate movable toward and away from a clutch center to press input-side rotating plates and output-side rotating plates. An oil flow hole is located in a spline groove to penetrate an outer peripheral wall of the clutch center, to enable clutch oil having flowed out of an output shaft to be discharged to outside of the clutch center, and located between an end of a center-side slipper cam surface in a second circumferential direction and a center-side cam hole located ahead, in the first circumferential direction, of the end in the second circumferential direction, in the circumferential directions. A through hole is located ahead, in the first circumferential direction, of the end of the center-side slipper cam surface in the first circumferential to guide clutch oil flowing outside the clutch center to the inside of the clutch center.

摘要： A clutch device includes a clutch center and a pressure plate operable to move toward or away from the clutch center and rotatable relative to the clutch center. The pressure plate includes a pressure-side cam portion. The clutch center includes a center-side cam portion. The pressure plate includes a boss extending in movement directions. The clutch center includes a through hole in which a boss is insertable. The through hole extends along circumferential directions and allows movement of the boss along the circumferential directions and the movement directions. While a surface of the pressure-side cam portion and a surface of the center-side cam portion are in contact with each other, a distal end of the boss projects outward from the through hole.

摘要： Provided is a clutch friction plate and a clutch device configured so that stiction torque can be reduced and each of in gear, shift feeling, and neutral find can be smoothly performed. A clutch device (100) includes clutch friction plates (101). In the clutch friction plate (101), multiple small-piece-shaped friction members (103) are radially bonded to surfaces of a core bar (102) formed in a flat-plate annular shape through an oil groove (105). Each friction member (103) includes an outer side (104a) facing an outer edge portion of the core bar (102) and an inner side (104b) facing an inner edge portion of the core bar (102) and extending parallel to the outer side (104a), and is formed in a rectangular shape. The friction members (103) are bonded onto the core bar (102) in such a direction that the outer side (104a) and the inner side (104b) are inclined at an inclination angle (θ) with respect to a perpendicular line (CL) perpendicular to a line (OL) connecting the center (O1) of the core bar (102) as the center of rotation of the clutch friction plate (101) and the center (O2) of the friction member (103).

摘要： A multiplate friction clutch includes: a pressure plate having a boss portion which penetrates a clutch center; a clutch lifter plate joined to the boss portion and receiving a drive force in a axial direction at a time of disconnection between a friction plate and a clutch plate; and a spring sandwiched between the clutch lifter plate and the clutch center, and capable of generating an elastic force in a direction that the friction plate and the clutch plate are pressed to each other. A position restricting portion is provided on the clutch lifter plate, the position restricting portion being brought into contact with the boss portion from an outside in a radial direction of the clutch lifter plate so as to restrict a position of the clutch lifter plate with respect to the pressure plate.

摘要： A clutch system includes a friction clutch and a ramp system. The friction clutch is a multiplate clutch, for example, for transmitting a torque between a torque-introducing element (i.e., an engine drive shaft) and a torque-discharging element (i.e., a transmission input shaft). The ramp system includes an input ramp, an output ramp, a pilot clutch, an actuation element, and a freewheel. The output ramp is rotatable relative to the input ramp to change an axial extent of the ramp system. The pilot clutch is for initiating rotation of the input ramp relative to the output ramp when there is a differential speed between the torque-introducing element and the torque-discharging element. The actuation element is for actuating the pilot clutch. The freewheel is arranged in a torque path in parallel with the friction clutch, and arranged to transmit a torque flow from the torque-introducing element to the torque-discharging element and interrupt a torque flow from the torque-discharging element to the torque-introducing element.

摘要： A hydraulic fluid pressure operated torque transmitting assembly for use as a brake or clutch which utilizes hydraulic pressure operated cylinders in a housing moveable with respect to an axially stationary spring housing to move a pressure plate against rotating discs and reaction plates. Hydraulic fluid pressure disengages the torque transmission and loss of hydraulic pressure enables springs in the spring housing to move the pressure plate to engage the friction discs for torque transmission. Radially removable spacers permit the spring housing position on mounting studs to be adjusted for compensating for friction disc wear. The hydraulic cylinders each have a drain port communicating with an annular collector groove in the cylinder bore. The drain ports are interconnected through flexible conduits connected to a master drain port in the cylinder housing.
