Abstract: A wheel flange lubrication system for rail vehicles is described consisting of a rigid lubrication block, which is forced against a wheel flange to provide lubrication to the wheel flange. The block or stick is maintained in position to reduce flange wear, to minimize the movement of lubricant to undesirable locations, such as the crown of the rails and the tread of the wheel, and to provide a lubrication system which is environmentally safe. Preferably the lubrication block is arc shaped and spring-forced laterally and radially into the flange. The lubrication system is designed to stay in contact with the wheel flange and apply the desired amount of lubrication in the flange area using the side contact surface of the block. This adjustable position control is provided by applying independent forces which are directed radially towards the crotch of the wheel and laterally towards the wheel flange. The lubrication system is applicable to single or two flange wheels.

Abstract: The pin and center link of the invention is used in a rivetless chain. It is manufactured to contain a reservoir to receive a lubricant. The reservoir may be in the form of a hole or a groove of various configurations. The lubricant is inserted into the pin or center link to provide lubrication to the center link/pin interface for extending the life of the chain. The size and location of the reservoir are selected to optimize the overall balance between load bearing strength and lubricant surface area at the center link/pin interface. The lubrication system of the present invention will also prevent leakage of lubricant onto the product and provide a clean environment.
