SELF-PROPELLED WORKING MACHINE INTENDED FOR OPERATION IN WINTER CONDITIONS Russian patent published in 2016 - IPC B60K28/00 E02F9/20 

FIELD: machine building.

SUBSTANCE: invention relates to self-propelled working vehicles, suitable for operation at low ambient temperature. Vehicle comprises a body with an installed on it internal combustion engine (ICE) and transmission, an undercarriage, consisting of a wheeled or caterpillar drive and a bracket, working equipment, cabin with the operator workstation, power supply system and monitoring and control system, which includes ICE controls and drives, transmission and working equipment, sensors of working and diagnostic parameters of the vehicle, sensors of its operating conditions, operator panel and controller with non-volatile memory. Vehicle implements various technical solutions ensuring possibility of operation at low ambient temperature, including optimal control of a group of electric heaters of the vehicle assemblies and units, limitation of parameters of speed and load modes of operation depending on ambient temperature, use of controlled heat insulation of assemblies and units of the vehicle, automatic opening of the emergency evacuation hatch, prevention of the vehicle running gear freezing into soil.

EFFECT: there is achieved a possibility of the vehicle operation at low values of ambient temperature, higher safety of the vehicle operation at low ambient temperature.
