Transmission/casing assembly with torque distributing device

An improvement in a motor vehicle transmission/casing assembly where a casing of said transmission/casing assembly includes a hydraulic cylinder having an interior shoulder in a plane that is perpendicular to a longitudinal axis of a motor vehicle transmission of said transmission/casing assembly and said casing further includes a plurality of spaced channels along interior walls of said casing, each channel defined by walls in said casing, each channel of said spaced channels being substantially transverse to said interior shoulder and terminating at a plane below said interior shoulder, and a pressure plate means, of a clutch plate assembly, said pressure plate means having externally extending splined members, and is supported on said interior shoulder between said casing and said transmission wherein a spline member of said spline members of said pressure plate are positioned in said spaced channels on a basis of one spline member of said spline members of said pressure plate in one channel of said spaced channels, respectively, said improvement comprising:

• a buffer means interposed between said walls of said channel and a spline member of said pressure plate means, for intercepting an energy transmitted by said spline member to a wall of said walls of said channel and for distributing said energy throughout a mass defining said buffer means and for transmitting said energy to said walls over an extended surface of said mass of said buffer means;
• wherein said interior walls of said casing includes a groove means following a circumference of said interior walls for seating a snap ring, and a snap ring means seated in said groove means for limiting movement of said buffer means along said channel.
