Abstract:
Disclosed is a wet friction member for use in a wet clutch or a wet brake that has improved heat conductivity and tends not to damage a mating plate which is engaged with it to improve the endurance of the mating plate. The wet friction member 1 includes base paper formed from a fiber base material and a filler and a binder for curing the base paper. The base paper contains a carbon-based material and does not contain diatomaceous earth.

Abstract:
A two-way clutch includes an outer race having a cam section in an inner periphery, an inner race that is separated in an inside diameter direction with respect to the outer race, and is disposed concentrically to be relatively rotatable, a torque transmission member that is disposed between the outer race and the inner race, and transmits torque, a cage that is capable of engaging with the torque transmission member and is movable in a circumferential direction, a drag strip that is supported by the cage, and a switching mechanism that can cause the two-way clutch to take at least a state locked in two directions by causing the drag strip to slide onto the inner race.
Abstract:
In a roller type one-way clutch comprising: an outer race; an inner race that is apart from the outer race on an inner diameter side in a radial direction and concentrically arranged to allow its relative rotation; a plurality of rollers that are arranged between the outer race and the inner race and transmit a torque between the outer race and the inner race; and a plurality of block bearings that are arranged between the rollers and between the outer race and the inner race, the roller type one-way clutch is characterized in that a curvature in a circumferential direction of a bearing surface of the block bearing facing an outer peripheral surface of the inner race is higher than a curvature in the circumferential direction of the outer peripheral surface of the inner race.
Abstract:
Provided is a roller type one-way clutch that can prevent rollers from coming off at the time of conveyance and assembling of an outer race without increasing a cost and a weight. The roller type one-way clutch includes: an outer race having pockets that have a cam surface formed on an inner surface thereof; an inner race that is apart on an inner diameter side in a radial direction from the outer race, concentrically arranged to allow its relative rotation, and has an annular outer peripheral raceway surface; a plurality of rollers each of which is arranged in each pocket, engaged with the cam surface, and transmits torque between the outer race and the inner race; and springs each of which is arranged in each pocket and energizes each roller by one end portion thereof in an engaging direction with respect to the cam surface, the other end portion of each spring is fixed to the outer race, and a support portion that supports each roller in a radial direction is provided at the other end portion.
