Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lubricant supply device mounted on a bogie frame when a vehicle passes through a curved section.
The lubricant supply device for the rear axle of the bogie in the traveling direction of the vehicle
The present invention relates to a railroad vehicle wheel tread lubrication device for directly applying a lubricant to a wheel tread. 2. Description of the Related Art When a railway vehicle passes through a curve, particularly when passing through a sharp curve section having a small curve radius, a very large vertical and horizontal slip occurs between the wheel and the rail. appear. As a result, creaking noise, vibration and noise are generated, and corrugated wear, direct wear of wheel flanges, and lateral pressure increase, leading to deterioration of ride comfort and increase in vehicle repair, and a decrease in running safety. Was. [0003] In order to solve the problem in such a sharply curved section, a method of providing an oiling device on the rail side and applying oil to the side surface of the head of the rail has been conventionally used. In Canada, a system is used in which solid lubricant is constantly pressed against the wheel tread. [0004] Although the above-mentioned method of constantly pressing the solid lubricant has a simple mechanism, the use of the solid lubricant in a straight section or a curved section with a large curve radius where no problem such as squeak noise occurs is wasteful. As the consumption of solid lubricant is severe,
Vehicle maintenance increases. [0005] As described above, the method in which the solid lubricant is constantly applied to the tread of the wheel is more effective than the method in which an oiling device is provided on the rail side to apply oil to the rail. However, it has the above-mentioned problems. The present invention solves the problem of the method of always applying the solid lubricant to the tread surface of the wheel, and in order to solve the problem, the lubricant supplied to the bogie frame in a sharp curve section where the lubricant needs to be applied.
Lubrication of the rear axle of the bogie in the direction of travel of the vehicle
An object of the present invention is to provide a tread lubrication device for a wheel of a railway vehicle in which only an agent supply device operates. [0007] To achieve the above object, a tread lubrication device for a wheel for a railway vehicle according to the present invention provides a solid lubricant held by a support for moving forward and backward by a mechanical or electric drive source. A flexible lubricant supply device was attached to the bogie frame so as to face the wheel tread surface .
The rear wheel of the bogie relative to the traveling direction of the vehicle in the lubricant supply device
Only the lubricant supply device for the shaft is configured to actuate the drive source to press the solid lubricant against the tread, detect a deviation from the curve, and return the solid lubricant. The drive source includes a mechanical mechanism including a lever and a spring that operates when a bogie angle exceeds a certain limit value (set value), and an air / hydraulic mechanism performed by a cylinder by opening and closing a solenoid valve by a relay. And an electrical mechanism that excites a solenoid by the operation of a relay. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The wheel tread lubrication device of the present invention comprises:
The solid lubricant held by the support is made movable by a mechanical or electric drive source and a lubricant supply device is attached to the bogie frame opposite to the wheel tread surface, and the drive source is activated upon detecting a curved approach. Then, the solid lubricant is pressed and applied to the tread surface, and the means for detecting the entry of the curve is not particularly limited, and a known detection method can be used. For example, as shown in FIG. 1, when a vehicle travels in a curved section, a rotation angle α occurs between the vehicle body and the bogie. Since the rotation angle α is inversely proportional to the curve radius R, by measuring the rotation angle α, the curve radius R can be obtained from the equation of R = L / sin α. Thereby, a curve can be detected. In addition, a method of inputting a signal from a ground member provided on the approach side and the exit side of the curve to a control device on the vehicle and calculating and detecting the curve, or a method in which curve information of a traveling route is previously transmitted to the control device. There is a method of detecting a curve by inputting and comparing it with the actually measured traveling distance, and a method of detecting a curve by receiving a radio wave from a space satellite and measuring the current position of the vehicle. As described above, when the vehicle enters a sharp curve by various detection methods, the bogie frame is detected based on the detection.
Of the lubricant supply device attached to the
Only the lubricant supply device for the rear wheel axle of the bogie is driven mechanically or electrically to extrude the solid lubricant in the holder and press it against the tread of the wheel to apply the lubricant. According to the present invention, a lubricant supply device mounted on a bogie frame in a sharp curve section where squeak noise or the like occurs.
Since the lubricant is applied to the wheel tread only by the lubricant supply device for the rear axle of the bogie in the traveling direction of the vehicle, the consumption of lubricant is reduced, and the replacement cycle due to the consumption of solid lubricant is reduced.
