摘要

A gear box (9) for a vehicle having at least two driving wheels (10) each driven by a traction chain (8, 12, 9, 11) including an electric machine (12) driving a primary shaft (8), the electric machine (12) being mechanically connected to the primary shaft (8), a wheel (10) being driven by a secondary shaft (11), a gear change including a counter-rotation phase followed by a jaw clutching phase in which a sleeve (21) connected to the shaft (8, 11) meshes in the receiving clutch sleeves (41) connected to the other shaft (8, 11), wherein during the jaw clutching phase, the electric machine (12) is controlled for imparting to the primary shaft a torque that generates a rotation in a direction opposite to the rotation movement due to the ratio change.
