Ama-couplings e-GS aklanyelwe ukudlulisa i-torque phakathi kwezinto zokushayela nezinto ezishayelwa ngamahabhu emihlathi egobile nezinto ze-elastomeric ezivame ukwaziwa ngokuthi izicabucabu. Ukuhlanganiswa phakathi kwalezi zingxenye kunikeza ukudambisa kanye nendawo yokuhlala yokungahambi kahle. Lo mkhiqizo utholakala ngezinhlobonhlobo zezinsimbi, ama-elastomer kanye nokulungiselelwa kokukhweza ukuze uhlangabezane nezidingo zakho ezithile.
