io Differential creepage control system for optimizing adhesion of locomotives By www.freepatentsonline.com Published On :: Tue, 31 Jul 1990 08:00:00 EDT This invention concerns a creepage control system for locomotives that optimizes adhesion while minimizing wasted energy, rail/wheel wear and shock loading on the drive train. The basis of the invention is to always maintain a small but positive value of the slope of the wheel-rail adhesion creep curve (or differential of adhesion versus creep) for all traction axles of the locomotive through microprocessor control. The value of the differential of adhesion versus creep is used to define an operating window for control and operation of motors continually in the optimum domain when high adhesion is demanded. When, due to a sudden increase in rail contamination, the value of the control function becomes negative, the microprocessor control reduces the generator excitation in stages until the function becomes positive and inside the operating window again. The microprocessor controls a rail cleaning system which is turned on or off depending on the cleanliness of the rail. It also controls a rail sanding system which is turned on or off depending on the magnitude of wheel creep. Full Article

The controller further compares the determined per unit creep of the axle, the tractive effort of the axle and the state of the friction modifying applicator associated with the axle to a predetermined value indicative of the health and functionality of the locomotive friction modifying system. The controller provides an indication of the health and functionality of the locomotive friction modifying system. Full Article
io Method and system of limiting the application of sand to a railroad rail By www.freepatentsonline.com Published On :: Tue, 06 Nov 2007 08:00:00 EST A method and computer program product of limiting sand use in a railroad locomotive sanding system applying sand to railroad rails to enhance adhesion of wheels of a railroad locomotive on a track having a pair of railroad rails, the sanding system including a plurality of sand applicators for each rail for directing sand flow toward the rail and with the locomotive having two trucks carrying the wheels for supporting and propelling the locomotive along the track. The method and computer program product may include steps of automatically controlling a flow of sand applied to the rail by the locomotive sanding system to limit the application of sand to situations in which applying sand to the rail would be effective to increase the adhesion of at least one of the railroad locomotive wheels on the rail by a predetermined incremental amount. The operation of each of the plurality of sand applicators may be independently controlled for selectively operating those sand applicators whose operation will result in at least the predetermined incremental increase in adhesion of the locomotive wheels on the rail, while not operating the other sand applicators so as to limit the amount of sand applied to the track.

io Apparatus and method for controlled application of railway friction modifying agent By www.freepatentsonline.com Published On :: Tue, 29 Sep 2009 08:00:00 EDT A system and method for controlling an application of a friction modifying agent to an area of contact between a railway wheel and a railway rail over which the wheel is traversing to selectively modify the coefficient of friction at the contact area. A sensor is used for detecting a parameter relating to the operation of the railway train. A controller is responsive to the sensor for selecting one or more of a plurality of friction modifying agents and controls the application of the agent to the rail as a function of the parameter. An applicator is responsive to the controller and applies the friction modifying agent to the area of contact between the railway wheel and rail. A second application of the agent may be predicated upon the effectiveness of a first application of the agent. The selection of the appropriate agent may include a consideration of a current location of the railway vehicle. Full Article
io Friction modifier applicator system for traveling cranes By www.freepatentsonline.com Published On :: Tue, 13 Apr 2010 08:00:00 EDT A friction management system for a traveling crane applies a liquid or solid friction modifier (FM) in precisely controlled quantities to the crane wheels or rail to improve performance and safety during movement of the crane. The friction modifier is applied by a nozzle mounted on a crane truck, which nozzle is opened and closed by a valve. The duration of the valve opening per second, which controls the friction modifier application rate, is approximately proportional to the average current draw, which is detected by current sensors connected to the truck motors.

io Gage side or field side top-of-rail plus gage corner lubrication system By www.freepatentsonline.com Published On :: Tue, 15 Jun 2010 08:00:00 EDT A rail lubricator for a railroad rail has a nozzle adjacent to the rail and attached thereto. The nozzle has a discharge orifice disposed beneath the top surface of the rail. The orifice is aimed generally longitudinally of the rail with the aiming including an upward component and a lateral component toward the centerline of the rail. Jets of lubricant project upwardly from the nozzle, arch above the top surface of the rail, and then fall onto the top surface and gage corner of the rail. This lubricates the top of a rail using an optimum amount of lubricant on the optimum area of the railhead. The lubricant is applied when the nozzles are spanned by a car. Full Article
io Traction material dispensing apparatus By www.freepatentsonline.com Published On :: Tue, 12 Jul 2011 08:00:00 EDT The traction material dispensing apparatus mounts within the wheel well of a fender of a vehicle and is therefore visually and physically unobtrusive. The apparatus selectively dispenses traction material both in front of and behind a vehicle tire. A driver-accessed switch controls the apparatus dispensing of material. Of importance is that the manifolds, funnels, and nozzles are gravity fed by the vessel so that agitators and pressurized material flow assistance is not needed. Flappers within each manifold are controlled by the driver-actuated switch and control delivery of the traction material to the nozzles. As with the flappers, flow from the nozzles is controlled by a miniature DC (direct current) motor powered by the vehicle's electrical system. Screens ensure breakup of any clumps and therefore proper dispersion of traction material to the roadway. Full Article
