A non-slip differential (1) has a frictional connection device which can be actuated by multiplying levers (8) arranged axially without spring loading in front of the pressure ring (7) of the frictional connection device, parallel to the latter and in a cross-section (13) of the ring, in such a way that the dimensions of the arrangement are approximately equal to the external dimensions of the pressure ring (7). Similarly, the depth of the free space (18) in front of the levers (8) on the side nearer the slip ring required for the oscillatory movements is approximately equal to the depth required for the oscillatory movements of the set of levers (8) only in the case of maximum deflection. The front support (9) of the levers (8) facing the pressure ring (7) is arranged in an edge region in the vicinity of the median active diameter of the frictional surface at a distance from the rigid rear support (10) equal to approximately only one and a half to two times the thickness of the levers, in such a way that a large difference between the lever arms and a high multiplication of force are obtained. The narrow sides of the rigid levers (8) abut rigidly and axially on an inner collar of the housing (2) and their opposite end is axially mobile against a servo-driven slip ring (12). This structure makes it possible to obtain a short, compact device, advantageous stressing of the frictional surfaces and load distribution, with direct linear force transmission, without an increase in servo power entailed by increased consumption of deformation energy and without the need for additional material and space for springs or hinges and their displacements when actuated. |
