TRACK-LAYING TRACTOR WITH ELECTROMECHANICAL DRIVELINE Russian patent published in 2015 - IPC B60K17/14 B60L7/20 B60L11/00 B60K6/00 

Abstract RU 2547154 C1

FIELD: transport.

SUBSTANCE: tractor contains internal combustion engine, generator connected with it, two electric motors mechanically connected with final reduction assemblies, track unit and attachment drive. Electric equipment system has DC segment and power electronic controllers. Low voltage part of this system contains accumulator battery, lighting devices, control instruments and other current consumers. In braking mode controllers provide changeover of electric motors into generator mode and generator - to electric motor mode. In this mode, kinetic energy of tractor motion is converted into electric energy and further transmitted to accumulator battery of electric equipment system low-voltage part, to drive of attachments and power-takeoff shaft, or dissipates in the form of heat in electric motor and generator.

EFFECT: effective service braking of track-laying tractor electromechanical driveline when its assemblies and aggregates are used without employment of additional devices specially intended for its braking and without special devices for accumulation and recovery of excessive energy generated in driveline power network during tractor braking, higher tractor reliability.
