The invention discloses an automatic dust removal device for an electric driving system of an electric bus. The device comprises a gas pumping pump, a gas storage device, an automatic exhaust valve, atwo-position four-way electromagnetic valve, an adjusting valve, a gas nozzle device, a gas exhaust device and the like, wherein the gas pumping pump is connected with the gas storage device througha pipeline, and the gas storage device is connected with a brake gas path, the automatic exhaust valve and the two-position four-way electromagnetic valve. The device has simple and reasonable design,when the vehicle is running, due to frequent braking and door opening and closing, the gas pumping pump is always in an intermittent working state, and the pressure of the gas storage device is highand low, when the pressure of the gas storage system is high, the conventional treatment mode is usually that the automatic exhaust valve is switched on to exhaust gas to the outside of the vehicle, and thus the waste of electric energy is caused when a gas source and the gas pumping pump are working. In this scheme, when the gas pumping pump is working, the gas discharged from the exhaust valve when the pressure of the gas storage device is high is reasonably utilized for automatic dust removal of the vehicle, and thus the electric energy is saved, and floating dust is removed in the electricdriving system.
Description
technical field [0001] The invention belongs to the technical field of electric vehicles, and relates to an internal dust removal device of an automobile, in particular to an automatic dust removal device for an electric drive system of an electric passenger car. Background technique [0002] At present, due to the increasing popularity of electric vehicles and the promotion of public transportation in cities. More and more parts of new energy vehicles are used in electric vehicles, such as electric vehicle high-voltage power distribution system, motor driver, three-in-one system (steering inverter, air pump inverter, vehicle DC / DC DC charger), Electronic water pumps and other equipment are essential components. Most of these equipment work under high voltage and high current conditions. During the working process, there will be temperature rise, which will cause the air around it to expand with heat and contract with cold, and dust and particles in the air will be removed. ...
