Abstract
A coasting clutch and a gear system with a coasting clutch include mutually facing first and second clutch members. The coasting clutch is arranged to operate in an engaged position, wherein the first and second clutch members are axially in mesh and rotating with the same speed, or overrunning and rotating with different speeds. The coasting clutch includes a coasting mechanism arranged to operate the coasting clutch into a coasting position when the clutch is overrunning. In the coasting position, the first and second clutch members are axially arranged further from each other than in the engaged position.

A coasting clutch comprising:
- mutually facing first and second clutch members,
- wherein the coasting clutch is arranged to operate in an engaged position when the first and second clutch members are axially in mesh and rotating with the same speed or overrunning and rotating with different speeds,
- wherein the coasting clutch further comprises coasting means arranged to operate the coasting clutch into a coasting position when the clutch is overrunning,
- wherein in the coasting position, the first and second clutch members are axially arranged further from each other than in the engaged position,
- wherein the coasting means is arranged to screw the second clutch member, in the rotational direction of the first clutch member, into the coasting position when the clutch is overrunning, and
- wherein the coasting means is arranged to limit axial movement of the second clutch member relative the first clutch member, to a coasting axial range, as long as the clutch is overrunning.
A coasting clutch comprising:
- mutually facing first and second clutch members,
- wherein the coasting clutch is arranged to operate in an engaged position when the first and second clutch members are axially in mesh and rotating with the same speed or overrunning and rotating with different speeds,
- wherein the coasting clutch further comprises coasting means arranged to operate the coasting clutch into a coasting position when the clutch is overrunning,
- wherein in the coasting position, the first and second clutch members are axially arranged further from each other than in the engaged position, and
- wherein energy for operating the clutch into a coasting position, is derived from relative axial movement between the first and second clutch members when the clutch is overrunning, and
- wherein the coasting means is arranged to screw the second clutch member, in the rotational direction of the first clutch member, and limit axial movement of the second clutch member relative the first clutch member, to a coasting axial range, as long as the clutch is overrunning.
