ABSTRACT:
In a motor vehicle transmission multiple-disc clutch assembly, a waved ring-shaped spring is provided within an annular groove formed in the clutch piston held within the clutch housing. The waved spring preferably is formed from spring steel and has five upwardly directed segments and five downwardly directed segments. When inserted in the annular groove and not flexed or compressed, a portion of the upwardly directed segments extends above the upper surface of the outer rim of the clutch piston by between about 0.025 to 0.040 inch. The waved spring opposes axial forces exerted on the clutch piston and the clutch pack (plurality of clutch plates) at a rate of 200 to 240 psi for the first 0.030 inch compression until it is substantially flattened with the upwardly directed segments to a height even with the outer rim of the clutch piston. The waved spring is free of radially extending projections or tabs and is movable with relation to the clutch piston.
