摘要： The invention relates to a fuel injection pump for an internal combustion engine, which fuel injection pump, for the drive of the same, is connected in a torque-transmitting manner by means of a clutch unit (1) to a drive input member, wherein the clutch unit (1) has a claw hub (10) which is arranged on the drive input member and is axially fixed and is driven in rotation, and wherein the rotational movement can be transmitted to a reciprocating and rotating pump member (11), and wherein the claw hub (10) and the pump member (11) have respective claws (12, 13) which are aligned counter to one another and which comprise lateral claw faces (15) between which is arranged a star-shaped and/or tongue-groove-like transmission body (14) which, for the transmission of the torque, adjoins the respective claw faces (15), wherein the claw faces (15) are formed with an outwardly arched, spherical surface in order to create at least one defined zone of force introduction from the transmission body (14) into the claw face (15), such that the stresses which occur in the claw (12, 13) as a result of the force transmission can be reduced. In this way, a fuel injection pump for an internal combustion engine with a clutch unit (1) is created which permits a long service life while at the same time permitting the transmission of large torques, and at the same time has a simple structural design.
