Analytical Design Study on TPEE CVJ Boots 2003-01-0675

To meet the long life expectancy and durability of the constant velocity joint (CVJ) boots an analytical study for CVJ boots using new material Thermoplastic Elastomer(hereafter TPEE) has been carried out in the paper. TPEE is known to be the new thermoplastic elastomer material featuring superior mechanical and chemical properties compared to the conventional chloroprene rubber. The deformation and contact characteristics of TPEE CVJ boots under the actual applied load conditions were analyzed through finite element method in the paper. The study has shown that the behavior of deformation and contact characteristics of TPEE CVJ boots under load can be modeled and predicted analytically. Also the study has shown that durability of the boots can be obtained by choosing the proper contraction ratio and thickness in the boots design.
