摘要

PROBLEM TO BE SOLVED: To provide a differential that benefits from a weight saving of partial or all-aluminum housings while maintaining the strength and economy of a cast iron housing.SOLUTION: A differential flange assembly is disclosed herein includes a flange member and a washer member. The flange member is defined by an engagement face and has an aperture through the engagement face. At least one slot is formed on the engagement face so as to extend radially outward from the aperture. The washer member has at least one tab extending from a peripheral edge of the washer member, and at least one opening. The tab is configured to be seated within the slot to mate the washer member to the engagement face of the flange member. The interaction between the slot of the flange member and the tab of the washer member prevents rotation of the washer member with respect to the flange member.
