<p>A self-locking differential device (1) for splitting a driving torque between a first shaft (11) and a second shaft (12) comprises a helical input ramp (17) for the driving torque, a first helical output ramp (18) and a second helical output ramp (19) which are able to transfer a first and a second output torque respectively to the first (11) and to the second (12) shaft, a clutch (14) collaborating with a pressure element (4) situated downstream of the driving torque input ramp (17). The first shaft (11) bears frictionally against the pressure element (4), the second shaft (12) bears frictionally against an element (2) situated upstream of the driving torque input ramp (17). The first output ramp (18) has a first screw pitch and the second output ramp (19) has a second screw pitch short of the first screw pitch.</p> |
