Composite component for use as adapter plate for retaining oil pump in housing of e.g. dual clutch gearbox of motor car, has flat contact surface for retaining oil pump, where composite component is made of aluminum alloy or steel

摘要

The composite component has a flat contact surface (6a) for retaining an oil pump, where the composite component is made of aluminum alloy or steel. A housing component partially encloses the composite component, where the housing component is made of magnesium alloy and formed as a centering plate (1) of a gearbox. A housing of the oil pump is made of aluminum alloy or steel. Passage or threaded bores (12) fix the oil pump, and passage openings (7, 8) are connected with sucking and pressurizing channels that run within the centering plate.
