Problems solved by technology

[0004] The invention provides a control method for automatically adjusting the height of the nominal traction point of a locomotive. Aiming at the problem that the wheel diameter of the locomotive wheel is constantly changing due to wear and tear during operation, and the height of the nominal traction point of the locomotive cannot always be at the optimal position, an automatic detection method is proposed. Control method for automatic adjustment of drawbar angle by wheel diameter and control device

Embodiment Construction

[0017] now attached figure 1 To attach image 3 To further explain the invention, the locomotive control system of the present invention detects parameters such as the running speed of the locomotive and the rotational speed of the traction motor to calculate the current wheel diameter of the locomotive, judges the value of the nominal height of the drawbar, and raises or lowers the drawbar by adjusting the telescopic device of the frame fifth wheel , so that the nominal height of the locomotive drawbar is matched with the wheel-rail adhesion in real time.

[0018] Set the locomotive wheel diameter D, the retractable height H of the fifth wheel, and the initial value M of the nominal height of the drawbar. The relationship value curve S is as follows: figure 2 As shown, after detecting the current wheel diameter d of the locomotive, the system compares it with the relational value curve S, and automatically adjusts the telescopic value h of the fifth wheel so that the nomina...

Abstract

The invention discloses a control method of adjusting the height of a nominal towing point of a locomotive automatically. A curve S of the locomotive wheel diameter D, the flexible height H of a traction base and the initial value M of nominal height of a traction bar is set as H=MD. After the current locomotive wheel diameter d is detected, the system is compared to a conditional value curve S toadjust the flexible value h of the traction base automatically, so that the current nominal height of the traction bar and the set curve M value are overlaid, and therefore, the adhesive utilizationratio of the locomotive is increased, and the idling of the locomotive wheel is reduced.

Description

technical field [0001] The invention relates to the technical field of locomotive wheel adhesion, in particular to a control method for automatically adjusting the height of the nominal traction point of the locomotive. Background technique [0002] The locomotive connects the bogie and the car body through the drawbar for power transmission. The height of the intersection of the extension line of the drawbar of the locomotive and the center line of the bogie is the height of the nominal traction point of the locomotive. Generally, the lower the height of the nominal traction point, the higher the adhesion utilization rate of the locomotive, and it is less likely to cause empty wheels to spin. [0003] Such as figure 1 As shown, the height a of the intersection point of the extension line of the locomotive drawbar and the center line of the bogie is the height of the nominal traction point of the locomotive. The rubber sleeves at both ends of the drawbar are respectively c...
