Railway tractor, as well as method, device and system for controlling same

Abstract

The invention provides a railway tractor as well as a method, a device and a system for controlling the same. The method comprises the steps as follows: when the railway tractor runs on a track, the pressure in rodless cavities of telescopic oil cylinders of a front guide wheel and a rear guide wheel of the railway tractor is monitored; and the pressure of the front guide wheel and the rear guide wheel on the track is controlled through the monitored result to enable the pressure of the front guide wheel and the rear guide wheel on the track to be kept within a preset range. The pressure between the guide wheels and the track is controlled through monitored pressure in the rodless cavities of telescopic oil cylinders of the guide wheels to cause the pressure between the guide wheels and the track of the railway tractor to be kept within the reasonable range, so that the problem that when the railway tractor runs on the track, the pressure between the guide wheels and the track is too high or too low is solved, and the safety and the traction performance of the railway tractor are improved.

Description

technical field [0001] The present invention relates to the field of vehicle design, more specifically, to a railway tractor and its control method, device and system. Background technique [0002] A railway tractor is a traction vehicle that can run on rails, including road and rail tractors, such as figure 1 The schematic diagram of the rail guiding system of the railway tractor shown, wherein, the system includes the front wheel guiding device (ie figure 1 The area indicated by the circle A in the center) and the rear wheel guide (ie figure 1 The area indicated by circle B in middle). When the railway tractor is running on the railway, the weight of the whole vehicle is supported by the front and rear guiding mechanisms (ie, the front guiding device and the rear guiding device) together with the tires, and the driving force is generated by the friction of the tires rolling on the rails. guiding role. When running on the railway, the front and rear guide wheels are com...

AI Technical Summary

Problems solved by technology

When the pressure between the guide wheel and the rail is too large, the supporting effect of the guide mechanism will make the pressure between the tire and the rail too small, and the friction between the tire and the rail will be too small during driving, resulting in too small driving force. The traction force of the railway tractor will be insufficient, losing the meaning of the railway tractor; when the pressure between the guide wheel and the rail is too small, the main force is the tire, so the rail landing pressure of the guide wheel will not be enough. When driving at high speed in the traction mode It is likely that the guide wheel will derail due to the elastic movement of the guide mechanism, and then the whole vehicle will be detached from the rail

[0003] Aiming at the above-mentioned problem that the pressure between the guide wheel and the rail is too large or too small when the railway tractor is running on the rail, no effective solution has been proposed yet
