Abstract

The invention discloses an energy-saving supercharging device of an automobile air compressor. The device comprises an air filter, a turbine supercharger, an air compressor and an air storage tank, wherein the air compressor is communicated with an air inlet cavity of an engine through an air inlet and communicated with the air storage tank through an exhaust port; the air inlet of the air compressor is provided with an energy-saving reversing valve which is connected with the air filter and the turbine supercharger respectively; and an unloading valve with a pressure feedback signal is arranged between the exhaust port of the air compressor and the air storage tank. Under the action of the energy-saving reversing valve, when the air compressor is no-load, the air enters the air compressor through a natural air inlet pipeline so that the air exhausted to the atmosphere does not consume the supercharged gas of the engine and the heat load of the air compressor is reduced; and when in full-load work, the compressed air from a braking pressure control air port pushes a power piston to move rightwards, then the natural air inlet is closed, a supercharged air inlet is connected, and the air compressor takes air from the turbine supercharger so as to improve the air inlet efficiency of the air compressor.

Description

technical field

[0001] The invention relates to a gas supercharging device, in particular to an energy-saving supercharging device for an air compressor for automobiles, and belongs to the technical field of air compressors for automobiles. Background technique

[0002] The main function of the car air compressor is to provide stable and sufficient compressed air for the braking system. With the rapid development of science and technology and the increasing safety requirements of users, the braking system of automobiles is becoming more and more complex, and the gas consumption is also increasing rapidly. Moreover, many devices that require compressed air support, such as air-suspended axles, air-suspended cabs and seats, and automated doors, have been rapidly extended to automobiles, which has overwhelmed traditional compressors, increased wear, and increased failure rates. The service life is shortened, and the oil leakage caused by wear and tear brings serious harm to th...
