Abstract

A drive system with a combustion engine also has a turbo-charger with a shaft supported by sleeve bearings in a housing. The housing is connected to the cooling water circulating circuit of the drive system for cooling the sleeve bearings and the housing of the turbo-charger shaft simultaneously with cooling the engine. A water pump wheel is mounted on the shaft in the housing for circulating the cooling water through the bearings, through the housing, and through the cooling circuit of the combustion engine, whereby the supply of cooling water to the sleeve bearings is load dependent.
