Torsional control for torque distribution

Abstract

( 57 )The invention proposes technical means for use of torsion reactions under torsional loadings of driving shafts in the control of all vehicles devices, which are functionally related to the interaction “wheels—road”. The driving torque to permanently connected driving wheels is transferred through an unit for formation of relative mobility ( 3 ). The unit detects changes in the cohesion of the permanently connected driving wheels with the road depending on the deformation of its sensitive to torsional loadings elastic elements ( 4 ). The unit ( 3 ) actuates a unit for conversion of the relative mobility into physical control actions ( 5 ). The unit ( 5 ) acts upon devices for control of torque distribution directly or by means of driving lines, which can be adjusted.
