Abstract
The invention proposes a friction coupling, in particular for use in motor vehicles, e.g. for controlling an air compressor, in which coupling at least two friction surfaces can be brought into frictional connection. According to the invention, two conical friction surface pairs are provided.
Claims12
A friction coupling in which at least two friction surfaces are brought into frictional connection, comprising:
- a coupling housing and two conical friction surface pairs, one pair including internal-cone friction surface elements that are mounted in an axially moveable manner and are coupled to one another, the other pair including external-cone friction surface elements, and a stop for at least one of the external-cone friction surface elements formed on the coupled pair of internal-cone friction surface elements, wherein the pair including the internal-cone friction surface elements is arranged inside of the coupling housing and contact points between the coupling housing and the internal-cone friction elements prevent radial twisting of the internal-cone friction elements, and
- wherein the external-cone friction surface elements are formed on surfaces of external-cone friction elements that are positioned adjacent to each other and a pre-stressed spring is arranged between the external-cone friction elements and pushes the external-cone friction elements apart to force the external-cone friction surface elements into contact with the internal-cone friction surface elements.
