Abstract
The utility model discloses a rim oil injection automatic control device for a railway locomotive. Based on the original rim oil injection control device, a humidity sensor circuit is additionally arranged, is electrically with a microprocessor circuit, and is used for detecting the humidity around wheels and sending detection results to the microprocessor circuit. When the humidity is high, less oil is injected. The action of a relay output circuit is controlled by the microprocessor circuit according to the detection results, the oil injection amount is controlled, and the lubricant is effectively saved.
Description
Technical field
The utility model relates to the local automatic guidance of railway locomotive, is specifically related to a kind of railway locomotive wheel rim oil spout automatic control device.
Background technology
Traditional wheel rim of locomotive oil spout all is manually to be controlled by the driver, and in complicated location, driver's labour intensity forgets greatly and easily, and manually control exists also that injection time is inaccurate, the problem of the bad control of fuel charge simultaneously.Increasingly high along with locomotive automation, intelligent degree, arise at the historic moment based on Embedded wheel rim oil spout control setup, information such as the kilometer post through collection vehicle, distance, the automatic guidance fueling injection equipment carries out oil spout to wheel rim automatically.
Through preliminary search, find that the technical scheme similar with the utility model has: application number be 200920063720.7 and the utility model patent of 200420068894.X two kinds of wheel rim of locomotive automatic injectors are disclosed respectively.Through initial analysis; Find that there is following defective in technique scheme: 1, only control according to signals such as vehicle operating control monitor unit in-to-in kilometer post, speed, distances; And ignore the factor that influences the vehicle real-world operation (like weather etc.), cause the lubricating oil waste; 2, injection time is fixed, and causes the lubricating oil waste when speed of a motor vehicle is fast.
Therefore be necessary prior art is improved.
