Coupling for drive of gear pump of fuel system of internal-combustion engine of commercial motor vehicle, has drive shaft exhibiting drive component, which transfers rotating motion of shaft to gear wheel and contains hard metal

摘要

The coupling has a coupling element connected with a gear wheel. A drive shaft and the gear wheel are coupled in a form-fit manner, where the drive shaft exhibits a drive component (34). The drive component cooperates with a recess of the coupling element and transfers rotating motion of the drive shaft to the gear wheel. The drive element contains a hard metal plate in a force transferring region, where the hard metal plate is non-detachably connected with a dihedron by adhering, caulking or riveting, and a clip connection.
