two-tandem drive axle transmission system, and vehicle comprising said towing transmission system

摘要

a two-tandem drive axle transmission system comprising a first axle (a1) and a second axle (a2) parallel to the first axle (a1) having opposite ends each suitable for supporting at least one wheel is described; an auxiliary shaft (ax) having a first end and a second end opposite the first, said first end being provided with a junction (in) to connect the auxiliary axis coaxially to a main drive shaft (ms) with said second end being stably connected to said first axis (a1) to rotate it; an intermediate axis (ia) having a first end and a second end opposite the first, said second end being stably connected to said second axis (a1) to rotate it; a transmission device (dtm) reversibly connected to said auxiliary axis (ax) for transferring the rotation of said auxiliary axis to said intermediate axis; actuation means configured to disable said elevator when said actuator actuates said connection between the transmission device (dtm) and the auxiliary shaft, and to activate said elevator when said actuator triggers a disconnection between said transmission device ( dtm) and said auxiliary axis.
