Abstract:
A transmission system for a vehicle comprises a primary shaft (10), a first planetary gear train (22a) and a second planetary gear train. The planetary gear trains comprise a ring gear (12), a carrier (14) for supporting planet gears (26), a first drive shaft mounted on the carrier of the first planetary gear train, a second drive shaft mounted on the carrier of the second planetary gear train, as well as secondary transmission devices for changing the rotation speeds of the ring gears of the first and second planetary gear trains. The secondary transmission devices comprise first control devices for changing the rotation speed of the ring gear of the first planetary gear train, and second control devices for changing the rotation speed of the ring gear of the second planetary gear train, the first and second control devices being independent of each other. Preferably, the ring gears are equipped with an external toothing (34), and said first and second control devices comprise a self- locking worm (20) arranged to engage the external toothing, and a control motor (18) for spinning the worm. In the method, the rotation speeds of the drive shafts of the vehicle are changed by adjusting the rotation speeds of the ring gears by secondary transmission devices independently from each other.

Abstract:
A wheel carrier assembly (10) of a machine for agricultural use, such as a tractor, having a drive axle (2) and steering wheels. The wheel carrier assembly (10) comprises: -.a constant-velocity joint (100) for the connection, upstream, of the wheel carrier assembly (10) to the transmission means, and comprising, downstream, a rotation shaft (101) for the rotation of the wheel assembly; - a disc brake device (200) for controlling the braking of the wheel assembly; - a gear reducer (300), connected to the wheel assembly and to the rotation shaft (101). The disc brake device (200) is operationally connected to the rotation shaft (101) in such a way that the braking action is applied directly on the latter, upstream of the gear reducer (300).
