DEVICE TO AUTOMATICALLY ADJUST STEERABLE WHEELS TOE-IN IN RUNNING Russian patent published in 2007 - IPC B62D6/04 B62D17/00 G01M17/06 

FIELD: transport engineering.

SUBSTANCE: invention can be used to provided automatic adjustment of toe-in of steerable wheels in motion and reduce to minimum wear of tires, reduce resistance to motion and consumption of fuel. Proposed device contains sensors of side reaction of road acting onto steerable wheels, reversing mechanism to change working length of steering tie-rod and system to control said mechanism electrically coupled with sensors of side reaction of road. Said sensors are made in form of strain gauge transducers electrically connected into bridge circuit. Taper bearings of steerable wheels are installed on bushings with beads fitted on axles of steerable wheels. Said sensors are secured on end face surfaces of bushing beads. Electric signal amplifier is installed between diagonally opposite pair of junctions of bridge and electromagnetic coil whose core is coupled with spool of distributor.

EFFECT: increased sensitivity, improved accuracy and reliability in operation.
