Locomotive wheel abrasion reducing and noise lowering control method and device

Abstract

The invention discloses a locomotive wheel abrasion reducing and noise lowering control method. During running of a locomotive, the method includes the following steps that the state of the locomotiveis judged, when the locomotive is in a first state, collecting of a rotating amount is performed; the rotating amount is compared with a set threshold value; when the rotating amount is larger than afirst set threshold value or the rotating amount is smaller than a second set threshold value, the rotating amount is converted into a curve radius; according to the value of the curve radius, the grease spraying amount is calculated and the wheel rim position needing grease spraying is determined; and grease spraying is quantitatively performed on the wheel rim needing grease spraying. When thelocomotive is in a second state, the above steps are not executed. The invention further discloses a locomotive wheel abrasion reducing and noise lowering control device. The locomotive wheel abrasionreducing and noise lowering control device and method serve as a brand-new locomotive wheel automatic abrasion reducing and noise lowering device and a control method. The rotating amount and the changing tendency of a vehicle body relative to a steering frame are collected, the curve radius is automatically judged, and therefore the independent action of grease spraying wheel positions and the grease spraying amount changing are achieved.

Description

technical field [0001] The invention relates to the field of locomotive control, and more specifically, to a control method and device for reducing wear and noise of locomotive wheels. Background technique [0002] When the locomotive passes through the curve, it needs to be guided by the rim, so that the bogie and the car body rotate relative to each other. At this time, the wheels rub against the rails violently, which greatly affects the service life of the wheels. The wheel wear and noise reduction device automatically sprays lubricating grease to the wheel rim according to the operating conditions, effectively reducing the friction between the wheel and rail, and improving the service life of the wheel. At present, the grease spraying method of the friction reduction device is mostly fixed-distance grease spraying. The number of grease spraying is controlled by calculating the walking distance of the locomotive, resulting in too many grease spraying times polluting the ...
