Gearbox, particularly for automotive vehicle with telescopic load-carrying arm

A gearbox adapted to transmit drive movement from an internal combustion motor oriented transversely, to at least one front or rear axle provided with driven wheels via at least one longitudinally oriented shaft, the gearbox comprising:

• a casing that contains an angled transmission having a transversely oriented input and a longitudinally oriented output defining a first shaft line of the gearbox;
• at least three parallel shaft lines comprising the first shaft line corresponding to the angled transmission, a second shaft line for transmission between the first and a third shaft line, said third shaft line corresponding to a drive shaft of a said front or rear axle;
• the first shaft line corresponding to the angled transmission comprising a double conical pinion engaging with a conical portion adapted to be driven by an output shaft of the motor and a double clutch for selectively driving a toothed forward drive wheel or a toothed reverse drive wheel, said two toothed wheels engaging continuously with toothed wheels on said second intermediate transmission shaft;
• and
• a torque converter structured and arranged to drive the transversely oriented input.
