Sažetak
Gradually stricter demands on carbon-dioxide (CO2) emissions reduction imposed by the European Union have proved as an efficient motivator for automobile manufacturers to develop novel technologies in order to electrify their respective fleets. Starting from 2020, the average emissions target for a manufacturer’s fleet is set below 95 g CO2/km, which corresponds to 27% reduction compared to the former target of 130 g CO2/km. In order to meet the new emissions regulation, road vehicles require additional technologies aimed at the reduction of energy demands from the internal combustion engine (ICE). A favourable solution from the standpoint of costs and simplicity of integration is a 48V electrical architecture utilizing a low-power induction machine, which operates both as a starter and a generator, and is coupled via a timing belt with the crankshaft of an ICE, widely known as the BSG (belt starter generator). BSG is a component of a compounded system named FEAD (front end accessory drive), an integral part of a P0 mild hybrid power-train, used for starting-up and boosting of the ICE power output, as well as recuperating energy used for the vehicle deceleration. The aim of this work was to design a vibration damping system for the belt transmission system within the FEAD which couples the BSG pulley with the ICE crankshaft pulley and to test the aforementioned system by means of simulations for realistic operating regimes of the P0 mild hybrid power- train.
