| 20140116288 | RAILWAY TRUCK HAVING TRACTION LINK - A railway truck is disclosed for use with a locomotive. The railway truck may include a first axle, a second axle, and a plurality of wheels connected to each of the first and second axles, and an equalizer operatively supported by the first and second axles in a vertical direction. The railway truck may also include a frame having a top side configured to face a bolster assembly and a bottom side configured to face a track. The railway truck may further include a longitudinal traction link pivotally connected between the frame and the equalizer above the top side of the frame. | 05-01-2014 |
| 20140245920 | FILTRATION SYSTEM AND METHOD FOR ENGINE AIR INTAKE - There is provided a method of filtration for a rail vehicle or other off-highway powered system. The method includes determining a filter load of a primary filtration system to an air intake of an engine. The method also includes determining that the filter load exceeds a specified threshold. Additionally, the method includes de-activating the primary filtration system. The method further includes activating a secondary filtration system to the engine. | 09-04-2014 |
| 20140261061 | FLEXIBLE DIRECT DRIVE BOGIE - The present invention relates to a flexible direct-drive bogie and implements a flexible frame by using a flexible cross beam, so as to make it easy for left and right side-frames to nod relatively to adapt to a larger twist of a track. As the frame is flexible, a primary suspension of the present invention is simplified to a thin layer of rubber pad, so that the production cost is reduced. Flexible drive devices enable flexible suspension of a permanent magnetic motor, and at the same time, can transmit torque, improve transmission efficiency, and reduce a weight of a transmission mechanism | 09-18-2014 |
| 20150321887 | TROLLEY - Provided is a trolley which is easily driven or braked. The trolley includes a body unit which moves along a rail and a power transfer unit which transfers power for driving or braking of the body unit, in which the power transfer unit includes an input shaft, an output shaft which receives power of the input shaft and transfers the power to the body unit, and a locking unit which transfers the power from the input shaft to the output shaft but does not transfer power from the output shaft to the input shaft. | 11-12-2015 |
