Torque transmission device for connecting hydraulic pump, of pump arrangement in pedal force servo system of motor vehicle, with electrical drive, has wheel provided with groove, where pin is engaged into groove and arranged in borehole

摘要

The device (1) has a shaft (2), and clutch units e.g. driver (3) and gear wheel (4), provided on both sides of the shaft. The driver has a recess (12), into which a dihedron (11) of the shaft is protruded. The gear wheel has an axial groove, where a pin is engaged into the groove and arranged in a radial borehole of the gear wheel. The recess corresponding with the dihedron of the shaft has spherical surfaces, which correspond with surfaces of the dihedron. The driver is made of a non-mineral thermosetting plastic and carbon-containing thermosetting plastic. The radial borehole is designed as a through-hole.
