A turbocompound unit

摘要

The invention relates to a turbocompound unit for converting energy of an exhaust gas from an internal combustion engine (10) to torque increase of a crankshaft (30) of the internal combustion engine (10). The turbocompound unit comprises a turbine arrangement (105) and means (106) configured to operatively connecting the turbine arrangement (105) to the crankshaft (30) via a hydrodynamic coupling (110) and freewheeling means (120). The turbocompound unit (100) further comprises brake means (130), wherein the brake means (130) and the freewheeling means (120) are located on an opposite side of the hydrodynamic coupling (110) in relation to the turbine arrangement (105).
