Hybrid drive module with chain drive

An engine assembly, comprising an internal combustion engine and a hybrid drive module, comprising a housing formed by an end section of an engine block of said internal combustion engine, and an ear structure extending out from said end section, and a cassette sealing the housing, the ear structure being arranged at a vertical position slightly above the lowermost point of a circular area of the end section, the housing enclosing a chain drive comprising a chain, the chain drive connecting an electrical motor with a crank shaft of the internal combustion engine via at least one coupling, wherein said housing further comprises a reservoir having an inlet for receiving oil from the chain during operation, and an outlet for distributing oil back to the chain.

A hybrid drive module, comprising a housing formed by an end section of an engine block of an associated internal combustion engine, an ear structure attached to the end section and extending outwards from the engine block, and a cassette sealing the housing, the ear structure being arranged at a vertical position slightly above the lowermost point of a circular area of the end section, wherein the housing encloses a chain drive comprising a chain, the chain drive connecting an electrical motor with a crank shaft of the associated internal combustion engine via at least one coupling, wherein said housing further comprises a reservoir formed by an insert arranged within the ear structure and being provided around and behind a first sprocket of the chain drive, said first sprocket being driven directly by the electrical motor, the reservoir having an inlet for receiving oil from the chain during operation, and an outlet for distributing oil back to the chain.
