Abstract: A drivetrain comprises a frame, two driving lines supported by the frame and supporting elements located within the frame and adapted to bear and/or sustain the driving lines themselves; the drivetrain further comprises at least an intermediate element directly interposed between the first driving line and the second driving line and adapted to share and transmit axial loads active in the first driving line into the second driving line and/or axial loads active in the second driving line into the first driving line and/or axial loads active into the first and/or second driving line into the frame.
