A clutch releasing device for positively releasing a clutch disc assembly from a flywheel of automotive vehicles which includes a first member disposed between the clutch disc assembly and a pilot bearing for receiving the extreme end of the transmission input shaft and which is in contact with the side face of an inner race of the pilot bearing, a second member operatively connected to the clutch disc assembly with respect to axial movement thereof and an annular resilient member disposed between the first member and the second member so as to cause the deformation of the annular resilient member when clutch is engaged. When the clutch is released, the clutch disc assembly is released by the resiliency of the annular resilient member from the flywheel until the annular resilient member returns to its original shape. The annular resilient member is axially slidably mounted on either the first member or the second member with a predetermined sliding resistance so as to cause slippage according to the wear of the friction facing of the clutch disc assembly, therebetween. The connection between the second member and the clutch disc assembly is radially outwardly positioned above spacer rivets of the clutch disc assembly so as to reduce the erroneous axial movement of the second member in assembling of the clutch.

Clutch releasing device

A V-pulley of variable pitch type for a drive acting through a tension medium strand includes two sheaves, at least one of which is displaceable in an axial direction relative to the other, each sheave having a running surface for a tension medium strand such as, for example, V-belts, at least one of the sheaves being mounted on a shaft-like member, at least two systems having means mutually connecting the sheaves to each other, the at least two systems being axially spaced from each other. Thus at least one system allows axial displacement of the one sheave linked thereto, and the other system is firmly linked to the other sheave. Two linked portions of the systems are located radially outside with respect to the running surfaces of the sheaves, thereby obtaining friction-free and wear-free entrainment and guidance of the movable sheave, and especially entrainment and guidance without the occurrence of fatigued corrosion to link means.

Variable pitch type V-pulley

A friction clutch comprising a driving and driven members to be operatively connected with or disconnected from each other by being axially pressed to or separated from each other, respectively. Both members are coupled through elastic damper means in engagement of the clutch to thereby provide cushioning service when the clutch is being engaged against an impulsive torque applied to the driven member particularly by a heavier weight of vehicles.
