DEVICE TO AUTOMATICALLY ELIMINATE ELECTRIC ROLLING STOCK WHEEL-MOTOR UNITS SKIPPING AND SKIDDING Russian patent published in 2009 - IPC B60L3/10 

FIELD: railway equipment.

SUBSTANCE: invention relates to electric rolling stock. Proposed device comprises pickups of current parametres to be read off the wheel-motor units, logical elements to extract maximum (MAX) and minimum (MIN) values from aforesaid current parametres, automatic actuators to act on the said units, logical element OR, computing unit and automatic regulator comparator element. Outputs of aforesaid pickups are connected to the said elements to extract maximum (MAX) and minimum (MIN) values from aforesaid current parametres. Inputs of the said logical element OR are connected to outputs of MAX and MIN elements. Computing unit inputs are connected to the outputs of pickups of current parametres. Outputs of logical element OR and computing unit are connected to comparator element inputs. The said comparator element incorporates linear amplifier connected to automatic actuator inputs.

EFFECT: higher reliability and efficiency.
