| 20120082407 | Railway car bearing seal spacer assembly - A bearing assembly is provided having a roller bearing with two cones defining an inner raceway fitted around the journal portion of an axle. A cup defines an outer raceway that combines with the inner raceway to receive roller elements. A spacer separates the cones, and a spacer support is provided to position and support the spacer. | 04-05-2012 |
| 20120046811 | Railcar Handbrake Monitor - A device for monitoring the status of a railcar handbrake having a hand operated handle, which device has a load bearing member configured to be inserted in the linkage of a railcar handbrake system so that the force applied to the brake system passes through the load bearing member. A strain gauge mounted on the load bearing member measures the strain. The information from the strain gauge is indicative of the force applied by the handbrake to the brake and is used to determine the status of the handbrake. Means for determining motion of the railcar is also provided. In one form, if it is determined that the brake is on and the railcar is in motion, information, such as an alarm, is transmitted. A system and method of monitoring a railcar handbrake are also provided. | 02-23-2012 |
| 20120037586 | Railway coupler knuckle - Railway coupler knuckle apparatus are described herein. An example railway coupler knuckle includes a tail portion, a hub portion and a transition portion joining the tail portion and the hub portion. The hub portion includes a generally cylindrical pivot pin passage having a longitudinal axis. The railway coupler knuckle has a cavity formed inside the tail portion and at least a portion of the transition portion and a first wall extends between surfaces of the cavity adjacent the transition portion. | 02-16-2012 |
| 20120037033 | Tapered brake beam wear liner - A brake beam wear liner for receiving a brake beam assembly includes a base wall extending between a rear end and front end. The base wall has opposite side edges. The base wall has a tapered thickness between the rear end and the front end with the base wall being thicker proximate to the rear end and being narrower proximate to the front end. The brake beam wear liner also includes side walls extending from the opposite side edges and flanges extending outward from the side walls generally opposite the base wall. The side walls and the base wall define an open ended trough configured to receive an end of the brake beam assembly. | 02-16-2012 |
| 20120037032 | Brake beam wear liner - A brake beam wear liner for receiving a brake beam assembly of a railway car truck includes a base wall having an inner surface and an outer surface extending between opposite side edges, and having a base wall thickness between the inner surface and the outer surface thereof. The brake beam wear liner also includes sidewalls extending from the opposite side edges. The sidewalls have inner surfaces and outer surfaces, and have a sidewall thickness between the inner surface and the outer surface thereof. The inner surfaces of the sidewalls and the inner surface of the base wall define an open ended trough configured to receive an end of the brake beam assembly. The brake beam wear liner also includes flanges extending outward from the sidewalls. The flanges have inner surfaces and outer surfaces, and have a flange thickness between the inner surfaces and the outer surfaces thereof. The base wall thickness is greater than the sidewall thickness. | 02-16-2012 |
| 20100288157 | SENSOR INTERFACE - A sensor interface is disclosed including a flexible substrate in which are embedded sensors for measuring physical parameters such as temperature, displacement, velocity, acceleration, stress, strain, pressure and force present between objects such as a railcar bearing and a truck side frame. The substrate is positioned between the objects of interest Electronic components such as a data processing unit, a data storage device, a communication device and a power source may also be embedded within the substrate. The electronic devices communicate with one another and the sensors to process signals generated by the sensors indicative of the parameters being measured. | 11-18-2010 |
| 20100174428 | Railroad Train Monitoring System - Railcar monitoring utilizes instrumented, flexible pads supported within the truck pedestal jaws on the bearing adapters. The pads contain sensors for monitoring temperature pressure, shifting loads, truck hunting and the like and have circuitry for processing information received from the sensors and for processing and reporting departures of performance variables to a remote source. The system cyclically activates polling each pad on a car and communicates signals of critical departures and car identity to a remote source. | 07-08-2010 |
