HYDRAULIC CONTROL UNIT HAVING INTERFACE PLATE DISPOSED BETWEEN HOUSING AND PUMP

摘要

A hydraulic control unit that delivers hydraulic fluid to a limited slip differential constructed in accordance to the present disclosure can include a hydraulic control unit housing, a motor, a gerotor gear assembly and an interface plate. The hydraulic control unit housing can have a housing mounting surface. The motor can include an output shaft and a motor mounting plate that has a motor mounting surface. The gerotor gear assembly can include an inner and outer gerotor gear. The outer gerotor gear can be formed of a first material having a first coefficient of expansion. The interface plate can be mounted between the housing mounting surface and the motor mounting surface. The interface plate can receive the outer gerotor gear in an interference fit. The interface plate is formed of a second material having a second coefficient of expansion that is substantially equivalent to the first coefficient of expansion.
