Abstract
A wet clutch is a clutch in a fluid setting. Wet clutches are typical in vehicle transmissions, for example. In this disclosure, a chemically-attached (chemisorbed) friction modifier on wet friction material surfaces provides improved performance in general with less dependence on the external parameters such as temperature and pressure. In one embodiment, the chemically-attached friction modifier is trichloro octadecyl silane (TODS).
Claims17
A friction material for a clutch pad comprising an aliphatic organosilane compound.
A friction material for a clutch pad, comprising:
- a base;
- and
- a friction modifier chemically-bonded to the base, the friction modifier including an aliphatic organosilane compound.
A method of manufacturing a portion of a clutch, comprising:
- attaching a friction material to a clutch plate;
- applying a solution including an alphatic organosilane compound to the friction material to cause a chemical attachment of the an alphatic organosilane compound to the friction material;
- and
- subsequent to the applying, heating the clutch plate in an oven.
