A shiftable friction clutch for gear drives, in which a shift collar is arranged axially movably on a carrier sleeve which is mounted on the shaft which must be coupled to a gear, and in which at least one axially movable friction ring is provided, which belongs to a first clutch half and which cooperates through clutch friction surfaces with a second clutch half and which is supported through rolling elements on the carrier sleeve for producing the contact pressure by means of pressure surfaces which are arranged on the front surfaces remote from the clutch surfaces and which are inclined with respect to the plane of rotation. The friction clutch is constructed as a spring-loaded safety clutch, in which the friction members which are pressed onto one another during the starting or engagement operation are supported against a spring.
In a shiftable friction clutch for gear drives comprising a shift collar axially movably supported on a carrier sleeve mounted on a shaft and which must be coupled to a gear, at least one axially movable friction ring constituting a first clutch half and cooperating with a second clutch half through clutch friction surfaces, said first clutch half being axially movably supported through rolling elements engaging inclined surfaces on axially mutually facing sides of said carrier sleeve and said friction ring, said inclined surfaces being inclined with respect to the plane of rotation, the improvement comprising wherein said carrier sleeve is mounted for axial movement on said shaft and wherein a supporting spring is provided on the side of said carrier sleeve remote from said clutch friction surfaces between said carrier sleeve and said shaft for limiting the maximum transmittable torque when said clutch friction surfaces are in engagement with each other.
