Abstract:
A clutch arrangement for use in a power tool having a multi-speed transmission assembly. The clutch arrangement includes a clutch member and a follower. The clutch member is coupled to a member of the transmission assembly that is proximate the torsional input of the transmission assembly and which must be in a non-rotating position to permit the transmission assembly to perform a torque multiplication operation. The follower is biased into engagement with the clutch member to inhibit relative rotation therebetween to permit the transmission assembly to perform a torque multiplication operation. When, however, the torsion that is exerted onto the clutch member is sufficient to overcome the frictional engagement between the follower and clutch members, the clutch member, and the transmission member, rotate, thereby inhibiting the capability of the transmission to continue to perform the torque multiplication operation.
