INSULATION STRUCTURE, METHOD FOR MANUFACTURE OF INSULATION STRUCTURE, RUNNING GEAR, AND REFRIGERATOR CAR Russian patent published in 2022 - IPC B61D3/16 E04B1/88 B32B27/40 

FIELD: railway transport.

SUBSTANCE: group of inventions relates to the field of railway transport, in particular to refrigerator cars, as well as to running gears of refrigerator cars. The running gear contains a steel structure, a support element, and an insulation structure. The insulation structure contains two outer panels and a set of insulating panels. Ends of insulating panels are connected to outer panels. Insulating panels are located at intervals, wherein heat-insulating chambers are located between neighboring insulating panels. Insulating parts are located in heat-insulating chambers. The steel structure is connected to the second outer panel, and the support element is connected to the first outer panel. The support element is equipped with a set of parallel grooves. Grooves are located at an interval.

EFFECT: heat-insulating characteristics of a car are improved.
