System for adjusting the tension of a belt component in a vehicle engine's belt gearing allows belt tension to be increased through a safety reserve by relying on a braking moment calculated in a controller

摘要

Belt tension (Psek,unk) as a target secondary pressure can be increased through a safety reserve (SR4) by relying on a braking moment (Mbr) calculated in a controller (101). The braking moment can be transmitted along a data line like a controller area network to a gearbox controller (18). Belt tension can be increased in good time, before torque vibrations travel in through drive pull.
