Title: Clutch piston for hydraulic transmission
Inventor: MASUDA MASAFUMI
IPC: F16D25/0635
Filed: 2001-11-01
Abstract: PROBLEM TO BE SOLVED: To realize manufacturing cost reduction and quality improvement by structuring a clutch piston for a hydraulic transmission so as to be manufactured in a simple way. SOLUTION: A seal ring 3 is structured so as to be separated from the clutch piston 1 and be post-fitted on the clutch piston 1. As a result, necessity of a complicated shape of clutch piston 1 being inserted in a forming die is eliminated, as found in a conventional method of vulcanization-bonding a lip 34 directly to the clutch piston 1. Thus, manufacturing cost for the die is reduced, and there becomes no fear of the shape accuracy of the clutch piston 1 being degraded due to heat, pressure or the like in vulcanization-bonding. The sealing ring 3 is manufactured only by vulcanization-bonding the lip 34 against a core bar 31 of simple shape, thus reducing manufacturing cost.
