Enhancement of Cup Seal Performance in Brake Wheel Cylinders by Hyper Elastic Analysis

Article of Honda R&D Technical Review Vol.13 No.1


The shape of the cup seal that is installed in the wheel cylinder of drum brakes was examined using FEA hyper elastic analysis. The cup seal material was changed from the often used SBR to EPDM resulting in enhanced heat and wear resistance. Next, a prototype cup seal was made in a determined shape based on the results of the investigations. Various durability tests were carried out with the results confirming both enhanced durability and appropriate sliding resistance.
