A method of performing regular maintenance in a hybrid drive module, comprising a housing (170) enclosing a continuous member drive (120) comprising a chain or a belt (126) connecting an electrical motor (110) with a crank shaft (22) of an associated internal combustion engine (20) via at least one coupling (130, 140), said electrical motor (110) being fastened with respect to the crank shaft (22) via fastening elements (111) wherein said method comprises: unfastening the electric motor (110) from said motor's (110) fastening elements (111); positioning the electric motor (110) such that the crankshaft (22) is a distance (d) from the electric motor (110) and such that tension in the chain or belt (126) is at or above a pre-specified level; and re-fastening fastening elements (111) such that the electric motor (110) is maintained at the distance (d) from the crankshaft (22).
A method of performing regular maintenance in a hybrid drive module, comprising a housing enclosing a continuous member drive comprising a chain or a belt connecting an electrical motor with a crank shaft of an associated internal combustion engine via at least one coupling, said electrical motor being fastened with respect to the crank shaft via fastening elements wherein said method comprises:
A hybrid drive module, comprising a housing enclosing a continuous member drive comprising a chain or a belt connecting an electrical motor with a crank shaft of an associated internal combustion engine via at least one coupling, said electrical motor being fastened with respect to the crank shaft via fastening elements wherein said motor is configured to be repositionable such that tension in the chain or belt is increased.
A hybrid vehicle, comprising a hybrid drive module comprising a housing enclosing a continuous member drive comprising a chain or a belt connecting an electrical motor with a crank shaft of an associated internal combustion engine via at least one coupling, said electrical motor being fastened with respect to the crank shaft via fastening elements wherein said motor is configured to be repositionable such that tension in the chain or belt is increased.
