Abstract: For reduction in size and weight, friction materials aiming at a high coefficient of kinetic friction have been developed. However, friction materials with a high coefficient of kinetic friction may cause sticking to a sliding partner material and deteriorated feeling in operation in particular in the initial running-in period during the initial stage of use. Therefore, the use of friction materials with a high coefficient of kinetic friction has been restricted. Since such sticking to the sliding partner material is less likely to occur after experiencing an initial running-in period, developed was a friction material in a form that is effective in prevention of sticking during the initial running-in period.

Abstract: Various pulley assemblies are described that include a pulley body, a hub defining an axis of rotation disposed within a bore of the pulley body, and an actuator and a clutch mechanism disposed about the hub. The actuator axially expands when the pulley body rotates in a predominant direction, and the clutch mechanism is activated thereby into an engaged position. In this engaged position, the clutch mechanism links the pulley body to the hub for simultaneous rotation in the predominant direction. Then, when the pulley body rotates in a non-dominant direction or experiences a deceleration, the pulley assembly enters an overrun position where the clutch mechanism disengages and allows the hub to rotate at speeds greater than the pulley body. Additionally, a reverse configuration is described where the actuator axially expands when the hub rotates and the clutch mechanism, when engaged, links the hub to the pulley body.
