Patent number: 7416262Abstract: A railway car brake system comprising a control device engageable with a predetermined portion of such railway car for compensating braking force in response to a load carried by such railway car. The control device includes a sensor mechanism engageable with a truck bolster or a movable car structure for sensing a vertical position thereof corresponding to a load carried by the railway car. There is a control valve engageable with the sensor mechanism which generates a fluid pressure signal responsive to such load. A pneumatic actuator engageable with a predetermined brake beam disposed on such truck assembly and connected to such control valve. This pneumatic actuator generates a predetermined braking force responsive to the fluid pressure signal and further responsive to the load carried by the railway car as sensed by the sensor mechanism. Such predetermined braking force may be proportionally adjusted to variations in the load carried by the railway car.Type: GrantFiled: June 6, 2005Date of Patent: August 26, 2008Assignee: Wabtec Holding Corp.Inventor: Michael E.

Patent number: 6938786Abstract: An improved ball and race connection assembly for use in connecting together adjacently disposed ends of railway vehicles is provided. This ball and race connection assembly is particularly useful as a connection member in slackless type drawbar assemblies. The improved ball and race connection assembly includes a race member which is formed from a polymeric and/or composite material, specifically a resin impregnated filament wound material which is wound on a polytetrafluoroethylene/polyester mesh sleeve and cured. The use of these materials enables the race member to have sufficient strength and to be self-lubricating, thus eliminating the costs of providing a lubricating material at the ball and race interface, as is necessary when using a metal race, as well as reducing the amount of friction at this interface resulting in lower L/V ratios.Type: GrantFiled: February 19, 2002Date of Patent: September 6, 2005Assignee: Westinghouse Air Brake Technologies CorporationInventors: Michael E.
