1. A manhole cover with a supporting structure device comprising: force distribution ribs for supporting a top surface of the manhole cover which can be driven over, anda preferably hollow force distribution cylinder arranged substantially centrally, in particular a circular force distribution cylinder, to support the force distribution ribs, characterized bya force distribution plate to relieve the load on the force distribution cylinder, wherein the force distribution plate at least substantially completely covers an underside of the force distribution cylinder in relation to the top surface, and whereinthe force distribution ribs transform smoothly into the force distribution plate. 2. The manhole cover according to claim 1, characterized in that two or more of the following parts are connected together integrally, namely the force distribution ribs, the force distribution plate and the force distribution cylinder. 3. The manhole cover according to claim 1, characterized by an in particular circular outer frame for supporting the manhole cover on a substrate, wherein the outer frame runs substantially along the outer periphery of the manhole cover. 4. The manhole cover according to claim 3, characterized in that the outer frame is formed integrally with the force distribution ribs. 5. The manhole cover according to claim 1, characterized in that the manhole cover consists of a material which comprises linear fillers and/or fibres to increase the strength of the manhole cover. 6. The manhole cover according to claim 5, characterized in that the linear fillers and/or fibres are oriented substantially parallel to the force distribution ribs. 7. The manhole cover according to claim 1, characterized in that the manhole cover and/or the force distribution plate have a substantially round, in particular circular outer form. 8. The manhole cover according to claim 1, characterized in that the manhole cover and/or the force distribution plate have a substantially polygonal outer form. 9. The manhole cover according claim 1, characterized in that the outer form of the manhole cover corresponds substantially to the outer form of the force distribution plate. 10. The manhole cover according to claim 1, characterized in that the force distribution ribs run substantially radially. 11. The manhole cover according to claim 1, characterized in that the force distribution ribs run substantially parallel to each other. 12. The manhole cover according to claim 1, characterized in that a cover plate forming at least a substantial part of the top surface can be arranged on the top of the manhole cover. 13. The manhole cover according to claim 1, characterized by a cover plate forming at least a substantial part of the top surface on the top of the manhole cover, wherein the cover plate is formed integrally with the manhole cover. 14. The manhole cover according to claim 1, characterized in that at least some of the force distribution ribs divide in the direction away from the force distribution plate. 15. A method for production of a the manhole cover with a supporting structure device comprising a force distribution plate, which relieves the load on a force distribution cylinder for supporting the force distribution ribs, wherein linear fillers, in particular linear fibres, are introduced in the production material of The manhole cover and first the force distribution plate and then the force distribution ribs are injection-moulded and/or pressed from inside to outside, in order to orient the linear fillers parallel to the force distribution ribs.
