摘要:
Wayside lubrication apparatus for railroad track wherein metered charges of lubricant are delivered to points spaced at intervals along the gage sides of the heads of the rails, and systems for and methods of monitoring the apparatus at a location remote from the site thereof.
摘要:
A wayside lubricator for railroad cars has a number of sensors mounted adjacent the track which detect the approach and passage rail cars. A lubricant supply and a pressurizing system are mounted adjacent the track and in fluid communication with a control valve and spray nozzle. The spray nozzle is aimed to shoot lubricant into a target zone when the control valve is opened. The spray nozzle is turned on for a defined duration of time so that the quantity of the lubricant is kept under control. Application of the lubricant to the wheels of the locomotive is avoided by detecting locomotive wheels and leaving the valve closed until they pass. This invention reduces the friction between the wheel tread and rail on curves for the trailing cars and thus reduces the friction and the force that is experienced by the wheel flanges on curves.
摘要:
A lubrication system mounted on a railroad locomotive for applying a lubricant to a rail. The system is comprised of a manifold that defines a generally endless, closed lubricant path. A pump is provided to continuously convey a lubricant along the lubricant path. A reservoir for holding the lubricant defines a portion of the lubricant path. A dispensing nozzle is mounted to the locomotive above each rail for directing the lubricant onto each rail. A metering device is associated with each dispensing nozzle. Each metering device is connected to the manifold and an associated nozzle for diverting a metered amount of the lubricant from the lubricant path to the associated nozzle.

A retrofit for an actuator element in a railway track lubricating apparatus for applying lubricant to a rail of a railway track includes a housing with a chamber, an enclosure block, a spacer element for occupying the space in existing actuator elements, a T-shaped plunger with a base adjacent a coil spring, and an actuator stem movable in a bore in the top of the housing, and wherein the stem is supported by and in sealed communication with a bushing that is placed within the cavity of the bore. A hydraulic fluid inlet opening is located at the bottom of the housing and a hydraulic fluid outlet opening is located at the top of the housing. A second embodiment provides an actuator element for use in new lubricating systems whereby the actuator element is mounted onto the rail and does not involve a spacer element in the chamber of the actuator element.

The tracks of a railroad yard system having an access track an a plurality of switches leading to a plurality of yard tracks are lubricated by a lubricating station positioned on the access track. The lubricating station has a positive displacement pump and dispenses a continues path of lubricant along a portion of track having a length equal to the circumference of a railroad car wheel such that the wheels will carry lubricant along the tracks of the system. Detectors are positioned on the yard tracks to determine the speed of the cars as they roll down track and into the yard tracks. A microprocessor receives information from the detectors and regulates the amount of lubricant dispensed through by the station.
摘要:
A device for lubricating a track or a rail that is adapted to be mounted tog wheeled vehicle. The device includes a frame member adapted to be mounted to the vehicle and an arm pivotally attached to the frame member. A roller, which is adapted to ride on the rail, mounts to the arm. A lubricating nozzle is secured to the arm.
摘要:
A wiper bar for application to a rail of a railroad track for applying lubricant to the head of the rail having a series of lubricant outlets and a rubber or the like guide or brush for confronting the gage face of the rail head and guiding lubricant discharged from the outlets up on the gage face, and the wiper bar/rail installation.
摘要:
A method for the lubrication of Vignole type railroad track, especially preceding a curved portion which is subject to wear by the wheel flanges of railroad cars, by applying lubricant essentially horizontally against the inner side of the Vignole type railroad track by an application device supplied with lubricant, wherein the lubricant is applied to the track through the movement of the application device along the track to be lubricated.
摘要:
A lubrication system for a railroad locomotive applies a lubricant with great accuracy in computer-controlled, precise quantities behind the last axle of the last locomotive such that the lubricant is consumed by the time the entire train has passed under all track, speed, temperature and train size conditions. Hydraulic pulse-width modulation (PWM or %PWM) controls the quantity of lubricant delivered. Time is divided into a series of windows each consisting of a few seconds. Lubricant delivered from a pressurized tank through long hoses to a solenoid controlled valve is then metered by the duration within this time window for which the computer computes and opens the valve. Compensation is provided for train tonnage and lubricant temperature as well as track curvature and train speed.
