In a two-axle drive system (10) for holding and moving large sunlight-absorbing, concentrating or reflecting surfaces about an azimuth axis (14) and an elevation axis (15), in the case of which a first gear unit which is driven by a first drive (43) is provided for a rotational movement about the azimuth axis (14), and a second gear unit which is driven by a second drive (45) is provided for a rotational movement about the elevation axis (15), the first gear unit being located in a first housing section (23), and the second gear unit being located in a second housing section (24), the first and second housing sections (23, 24) are immobile relative to each other. High stiffness is obtained as a result. |
