FIELD: transport.
SUBSTANCE: module is adapted to location inside caterpillar outline and comprises motor and final planetary reduction gear engaged therewith with drive sprocket fitted thereat. This process implements various alternative cooling methods which allow the increase in motor sizes and torque and rule out power takeoff for fan and circulation pump driving. Heat released by module is tapped to machine frame. High-temperature motors with low heat emission at rotor are used. Used are elements for efficient heat transfer from motor stator to module body or machine frame. Machine fame ribbing at module installation point is used and subjected to forced cooling. Traction module is divided to several lower-power modules to be used for actuation of caterpillar propulsor various elements. Electromagnetic parking brake is arranged outside the traction module. Besides, this module is mounted at machine frame and spaced from electronic power controller and other heat sources.
EFFECT: higher traction power factor.
