Le rôle de l'arbre d'entraînement

Le demi-arbre d'automobile est également appelé learbre de transmission, which connects the differential with the drive wheels. The arbre de transmission is the shaft that transmits torque between the gearbox reducer and the drive wheels. There is a universal joint (U/JOINT) at the inner and outer ends of the shaft, which is connected to the reducer gear and the inner ring of the hub bearing through the spline on the universal joint.

Learbre de transmissiontransmet la puissance du différentiel aux roues motrices gauche et droite.
Learbre de transmission is a solid shaft that transmits large torque between the differential and the drive axle. Its inner end is generally connected with the side gear of the differential through a spline, and the outer end is connected to the drive through a flange or spline. The wheel shells of the wheels are connected.
Lestructure of the arbre de transmissionest différent en raison de la structure de l'essieu moteur. Le demi-arbre de l'essieu moteur non déconnecté est un arbre plein rigide.
