Apparatus and methods for achieving a high strength bonded joint between a stub connector and a shaft.

A clutch as used, for example, in vehicle drives, in particular rail vehicle drives. A clutch is specified, by way of which the electric contact between the drive side and the output side of the clutch is prevented reliably, and a simple and inexpensive method for the production thereof is also specified. The problem is solved by way of a clutch, at least consisting of a clutch half on the drive side and a clutch half on the output side, wherein at least one clutch half has at least two hollow cylinders which are arranged above one another and are arranged in a bore of the clutch half, wherein the second hollow cylinder consists of electrically insulating material, and wherein at least the first hollow cylinder, at least on its outer circumferential surface, and at least the inner circumferential surface of the bore have knurling at least in part.

A steering shaft for a motor vehicle has an inner shaft, arranged in an outer shaft that is displaceable axially in the direction of an axis of rotation. The inner shaft includes axially running radial projections on its outer side. The outer shaft includes axially running grooves on its inner side, into which grooves the projections of the inner shaft engage in a positively locking manner in a direction of rotation and displaceably in an axial direction. With regard to fault-free operation during fluctuating temperatures, on the inner shaft, there is arranged a profiled sleeve with undulating cross-sectional profile, the inner surface of which lies against the flanks of the projections of the inner shaft and the outer surfaces of which lie against the flanks of the grooves of the outer shaft, wherein the profiled sleeve is connected to the inner shaft at one or more fastening points.
