DEVICE TO AUTOMATICALLY CONTROL CONTROLLED WHEELS TOE-IN IN MOTION Russian patent published in 2010 - IPC B62D6/04 G01M17/06 

FIELD: transport.

SUBSTANCE: invention relates to automotive industry and can be used to automatically control controlled wheels toe-in in motion. Proposed device comprises controlled wheels, hubs with outer and inner flanges, strain gages, axles, electric power supply, electric signal amplifier, electromagnetic coil, hydraulic control valve, vessel with work fluid, pump and cross link with reversing mechanism. Strain gages transudes of the road lateral reaction and are connected in bridge circuit with electric power supply and, via electric signal amplifier, with electromagnetic coil. Electromagnetic oil core is rigidly connected with spool-valve of work fluid flow control valve communicated with work fluid vessel, pump and hydraulic cylinder of reversing mechanism to vary work length of crosswise link. Rotary cam has three axial blunt holes. Three L-like levers are arranged on the ends of sleeves to support strain gages secured on face surface. Stepped ends of L-like levers of the sleeve inner ends have their narrow part entering said axial blunt holes made in rotary cam. Depth of blunt holes is larger than length of narrow part of the ends of said levers.

EFFECT: higher reliability, fast response and accuracy of automatic toe-in adjustment.
