Abstract:
1. An apparatus for the distribution of the traction forces between the road wheels on each side of a motor vehicle, comprising a differential gear comprising three shafts consisting of one input shaft and two output shafts and a self energizing locking device arranged between two of the three shafts of said differential gear, the function of said locking device, being controllable by means of a control signal between four distinct working modes, being describable as: a. said locking device is not prevented from functioning during differentiation in any of the two differentiation directions so that any differentiation will be automatically locked regardless of differentiation direction; b. said locking device is prevented from functioning during differentiation in a first differentiation direction so that any differentiation in said first direction will not be locked; c. said locking device is prevented from functioning in a differentiation direction opposite to said first direction so that any differentiation in said opposite direction will not be locked; d. said locking device is prevented from functioning during differentiation in any of the two differentiation directions so that no differentiation will be locked regardless of differentiation direction.
