Abstract: Provided is a torque damper device capable of setting high hysteresis in a wide range and improving assembling property and maintainability of a high friction material for generating the high hysteresis. A torque damper device 100 includes an output hub 104 and a flange 107 between a first input plate 101 and a second input plate 102 rotatably driven by a rotational driving force of an engine. The output hub 104 is formed in a cylindrical shape. The flange 107 is attached to a portion that projects radially outward of the output hub 104. Further, the output hub 104 is formed with a friction plate holder 106 on an outer peripheral surface thereof. The friction plate holder 106 is fitted to a plate-side fitting portion 111a of a first friction plate 111, and is formed to have an axial length longer than a total thickness of the first friction plate 111 and a first intermediate plate 112.

Abstract: A power transmission device has a pressure member 5, drive-side clutch plates, driven-side clutch plates, a clutch spring 10, a separate receiving member 11, and a back-torque limiting cam. A radially-outside restricting portion restricts radially-outward movement of the receiving member 11 relative to the pressure member 5. This maintains clearance t between a side surface 11d of the receiving member 11 and an inner peripheral wall 4e of a clutch member 4.

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: Provided is a wet friction plate capable of further reducing drag torque. A wet friction plate 200 is configured to include an oil groove 203 and a friction material 210 on a flat plate annular core metal 201. The friction material 210 is formed with ride-on sides 214a, 214b and a ride-on groove 215. The ride-on sides 214a and 214b respectively extend linearly between an inner peripheral edge portion 211 formed on an inner side in a radial direction of the core metal 201 and two circumferential end portions 213a, 213b respectively extending in the radial direction at both end portions in a circumferential direction of the core metal 201. The ride-on groove 215 extends in a concave shape toward an outer side in the radial direction of the core metal 201 at a central portion of the inner peripheral edge portion 211 in the circumferential direction of the core metal 201. Further, the ride-on sides 214a and 214b are respectively formed to extend in a direction away from an imaginary oil groove center line L from the circumferential end portions 213a and 213b toward the inner peripheral edge portion 211.

In the method for manufacturing a joint component 100, a hole-side weak press-fit portion 112 is formed at a hole 111 of a flat plate ring-shaped first member 110. Moreover, each of a shaft-side weak press-fit portion 122 and a shaft-side strong press-fit portion 124 is formed at a shaft portion 121 of a cylindrical second member 120. The hole-side weak press-fit portion 112 and the shaft-side weak press-fit portion 122 are defined by a first weak press-fit interference Lw1 formed thinner than a first strong press-fit interference Ls1. The shaft-side strong press-fit portion 124 is defined by a first strong press-fit interference Ls1 as the minimum necessary press-fit interference for electric resistance welding upon electric resistance welding between the hole 111 and the shaft portion 121.

A method for manufacturing an integrated member by welding a first member formed of aluminum alloy material and a second member formed of ferrous-based material characterized in that the first member contains a predetermined amount of silicon and has a thickness larger than that of the second member. The second member can be pressed against the first member along the thickness direction, and by electrically energizing the pressed-in portion during the pressing period, electric resistance welding can be used. The pressing-in amount is set to a value larger than the thickness of the second member and less than that of the first member. The overlapping margin of the first and second members is set to a value of 0.5 mm or more.
