The inventive drive system contains two oval wheels (9, 10), which are each fixed on one of two axles (3, 4). Said axles are parallel to one another and rotate in opposite directions in bearings (2) located in a plate (1). Two identical gear wheels (15) which engage with one another and which rotate uniformly each comprise an elastic coupling (14). A wheel (12) is flangemounted on each of said elastic couplings. The wheels (12) and the oval wheels (9, 10) are each arranged for holding a tension element (11), for example, a chain, a toothed belt or a reinforced round cord. The one wheel (12) drives the left oval wheel (9) with the one tension element (11), and the other wheel (12) drives the right oval wheel (10) with an additional tension element (11). When moving on rolling contact, the oval wheels (9, 10) satisfy the condition tan1 = 1/2tan2, whereby 1 is, for example, the angle of rotation of the left axle (3), and 2 is that of the right axle (4).
