ROAD TRAIN WITH ELECTRODYNAMIC DEVICE FOR STABILIZATION OF STRAIGHT-LINE MOVEMENT OF TRAILER Russian patent published in 2024 - IPC B60T13/08 B62D13/00 B62D53/00 

FIELD: vehicles.

SUBSTANCE: invention relates to road trains with single-axle trailers. Road train with electrodynamic device for stabilization of straight motion of trailer comprises tractor equipped with steering mechanism and braking system, and single-axle trailer. Two DC electric motor-generators are mounted on the trailer frame. Windings of rotors of left and right electric motors-generators are connected into separate circuits, each of which includes load resistor and four sensors for control of electric motor-generator, which are installed on the tractor: tractor controlled wheels position sensor with normally closed contacts, kinematically connected to the tractor steering wheel, trailer hitch angular deviation sensor in the horizontal plane relative to the tractor with normally open contacts, kinematically connected to the kingpin, sensor with normally open contacts of brakes activation, kinematically connected to tractor brake pedal, and sensor with normally open contacts of tractor reverse gear engagement, kinematically connected to tractor gearbox.

EFFECT: improved stabilization of straight-line motion of single-axle trailer at straight motion of tractor.
