Clutch assembly with formed retention ring

A clutch assembly for a transmission, comprising:

• a housing defined by a wall having an annular configuration circumscribing a clutch axis, said wall extending between an open end and a floor, said floor extending inwardly from said wall toward said clutch axis;
• a plurality of splines formed in said wall, said splines being spaced from said open end of said housing;
• a snap ring for retaining clutch plates in said housing;
• said open end of said wall being deformed inwardly toward said clutch axis defining a retainer for retaining said snap ring within said housing in a space disposed between said retainer and said splines;
• and
• said retainer includes a retainer wall disposed radially outwardly from said annular wall of said housing.

A clutch housing for use in a transmission, the housing enclosing clutch plates interacting with a drive shaft of a vehicle, comprising:

• a wall having a tubular configuration with an open end and a partially closed end, said partially closed end having a floor extending radially inwardly from said wall;
• a plurality of splines formed into said wall thereby providing gear like engagement with the clutch plates disposed inside said housing, said plurality of splines being spaced from said open end of said wall;
• a retainer defined by a hem extending from said open end of said wall, said hem extending radially inwardly from said wall for retaining a snap ring used to retain the clutch plate assemblies within said clutch housing;
• and
• said retainer defining a major retainer diameter, said housing defining a minor housing diameter and a major housing diameter, said major retainer diameter being greater than said minor housing diameter and said major housing diameter.

A clutch assembly, comprising:

• a housing having an open end and a floor, said housing defining an annular wall around a clutch axis with said wall defining a plurality of splines extending between said open end and said floor;
• a plurality of clutch plates received by said splines inside said housing and a ring retaining said clutch plates in said housing;
• a retainer disposed at said open end of said housing and defining a space with said splines, said space receiving said ring thereby securing said ring between said retainer and said splines in a substantially fixed position relative to an axis defined by said clutch assembly and retaining said clutch plates inside said housing, and
• said splines defining a major housing diameter and a minor housing diameter, said retainer defining a minor retainer diameter being truncated between said major housing diameter and said minor housing diameter.
