1. Improvements to wind turbines for electrical power production, of those consisting of a blade ( 4 ) rotor for harnessing the action of the wind, said rotor being mounted in a rotary arrangement with respect to the body ( 1 ) of the wind turbine in which inclusion is made of an electric generator driven by the rotary action of the aforementioned blade rotor, characterised in that the rotor bearing the blades ( 4 ) comprises a hub ( 3 ) that is prolonged at its rear with an extension ( 7 ) that constitutes an assembly shaft with respect to the body ( 1 ) of the wind turbine, with the aforementioned hub ( 3 ) and the shaft ( 7 ) forming a single manufactured piece assembly. 2. Improvements to wind turbines for electrical power production, all in accordance with claim 1, characterised in that the single manufactured piece assembly of the hub ( 3 ) and the shaft ( 7 ) configure a large space inside, with the rear attachment of a cover ( 9 ) that is an integral part of the end of the shaft ( 7 ) and upon which, and in axial attachment on the outer part, a boss ( 10 ) is mounted, with respect to which the manifold of the electric generator is mounted. 3. Improvements to wind turbines for electrical power production, all in accordance with claim 2, characterised in that the rotary assembly of the single manufactured piece assembly of the hub ( 3 ) and the shaft ( 7 ) is attach to the body ( 1 ) of the wind turbine by means of a back-end bearing ( 12 ) that is fitted between the boss ( 10 ) of the cover ( 9 ) and a support ( 14 ) attached to the casing of the body ( 1 ), and to a forward part between the actual shaft ( 7 ) and the casing of the body ( 1 ) by means of a front-end bearing ( 13 ). 4. Improvements to wind turbines for electrical power production, all in accordance with claim 1, characterised in that the rotary assembly of the single manufactured piece assembly of the hub ( 3 ) and the shaft ( 7 ) is attached to the body ( 1 ) of the wind turbine by means of a back-end bearing ( 12 ) that is fitted between the boss ( 10 ) of the cover ( 9 ) and a support ( 14 ) attached to the casing of the body ( 1 ), and to a forward part between the actual shaft ( 7 ) and the casing of the body ( 1 ) by means of a front-end bearing ( 13 ). 5. Improvements to wind turbines for electrical power production, all in accordance with claim 1, characterised in that the assembly of the single manufactured piece assembly of the hub ( 3 ) and the shaft ( 7 ), with respect to the body ( 1 ) of the wind turbine, is attached by means of elastomeric runners ( 15 and 16 ), which are mounted between the shaft ( 7 ) and the casing of the body ( 1 ), providing roller support in the radial direction and in the axial direction of the assembly. 6. Improvements to wind turbines for electrical power production, all in accordance with claim 1, characterised in that the blades ( 4 ) are mounted in a rotary assembly on the hub ( 3 ), with attachment made in relation to them of respective separate hydraulic drive cylinders ( 20 ) by means of which the blades ( 4 ) turn to adjust their yaw in response to the strength of the wind.
