Theka shaft ndi shaft yomwe imatumiza torque pakati pa gearbox reducer ndi gudumu loyendetsa (makamaka olimba m'mbuyomo, koma shaft yocheperako ndiyosavuta kuwongolera kusalinganika kozungulira. Chifukwa chake, magalimoto ambiri amagwiritsa ntchito ma shafts opanda kanthu). Malekezero ake amkati ndi akunja amakhala ndi cholumikizira chapadziko lonse lapansi (U / cholumikizira) motsatana, chomwe chimalumikizidwa ndi zida zochepetsera komanso mphete yamkati ya hub yomwe imadutsa pamzere wapadziko lonse lapansi.
Axle shaft imagwiritsidwa ntchito kusamutsa mphamvu pakati pa kusiyanitsa ndi gudumu loyendetsa. Theka la axle yamtundu wamba yosathyoka imatha kugawidwa kukhala yoyandama, 3/4 yoyandama komanso yoyandama molingana ndi mitundu yosiyanasiyana yothandizira kumapeto akunja.
