Road vehicle with hybrid propulsion

A road vehicle with hybrid propulsion, the road vehicle comprising:

• at least a couple of driving wheels;
• a thermal internal combustion engine;
• a double clutch gearbox provided with two primary shafts, two clutches interposed between the thermal internal combustion engine and the primary shafts, at least a secondary shaft constantly meshing with the driving wheels, and a plurality gear couples, each of them defining a respective speed and including a primary gear mounted on a primary shaft and a secondary gear which is mounted on the secondary shaft and constantly meshes with the primary gear;
• a first reversible electric machine having a shaft, which is coupled to a first primary shaft of the gearbox;
• a second reversible electric machine having a shaft, which is mechanically coupled to a second primary shaft of the gearbox different from the first primary shaft;
• a plurality of rotary fluid-dynamic machines, each of them to provide for an auxiliary service of the road vehicle and having a rotary mounted shaft to receive movement from the shaft of the first reversible electric machine;
• and
• a mechanical transmission, which couples the shaft of the second reversible electric machine to the shafts of the fluid-dynamic machines and includes an uncoupling device, which separates the shaft of the second reversible electric machine from the shafts of the fluid-dynamic machines.
