| 196 | Telescopic mechanism in telescopic hitch buffer device for use in high speed electric multiple units | US14470865 | 2014-08-27 | US09616904B2 | 2017-04-11 | Xiaozhong Lv; Hui Liu; Kai Chen |
| The patent was disclosed a telescopic mechanism in a telescopic hitch buffer device for use in high speed electric multiple unit (EMU) trains. The telescopic mechanism comprises a compression rod (2) located inside a movable housing (1) of said hitch buffer device, one end of said compression rod (2) being connected to the movable housing (1), and a bearing connector (3) encasing the compression rod (2). A guiding barrel (4) is fixedly mounted outside the bearing connector (3). An extension/retraction driving mechanism (9) is provided between the guiding barrel (4) and the movable housing (1). A locking mechanism comprises protrusions (6) distributed at the other end of the compression rod (2), and grooves (7) in engagement with protrusions (6) on the inner wall of the bearing connector (3). One end of the compression rod (2) is connected to the movable housing (1) via a torsion spring (5), keeping the compression rod (2) and the bearing connector (3) in a locked state; an unlocking driving mechanism is provided on the outside of the movable housing (1), and is in an unlocked state when the protrusions (6) face the grooves (7), in which case, the movable housing (1) and the bearing connector (3) can slide relative to each other. Since the extension/retraction driving mechanism (9) is provided inside the movable housing (1), volume is reduced, good protection is provided for respective components, and the telescopic mechanism and the locking mechanism are relatively simple in structure, labor-saving, reliable in operation, and can bear relatively large loads. | ||||||
| 197 | SYSTEM FOR MOUNTING A BRACKET TO A COUPLER HEAD | US14861250 | 2015-09-22 | US20170080955A1 | 2017-03-23 | Michael J. Foxx; Jason Reiling; Kevin P. McGarvey; George Vermesi |
| A coupler head and mounting bracket combination for supporting a brake hose fitting uses a lug formed integrally with the coupler head and a support bracket mating with the lug. In embodiments, the bracket may be installed in a plurality of vertical positions on the coupler head. The bracket is maintained in a position inboard of the lateral side of the coupler head, to reduce or eliminate the likelihood that the bracket will interfere with the other equipment or the car body. Embodiments of the invention are particularly adapted for “E” type and “F” type coupler heads. | ||||||

| Coupler head includes a coupler house for containing components included in a mechanical coupling and for supporting a front plate. The coupler house has two separate elongate shell-shaped house parts, which in mutually opposite and open long sides are individually joined to the outside of a beam running centrally in the coupler head and in a rear end is adapted to be coupled to a drawbar and in a front end adapted for bearing a main shaft included in the coupling, the parts being joined to the outside of the beam by welding seams running in the beam's longitudinal direction, whereby tractive forces are transferred from the coupling to the drawbar via the beam without loading the parts and seams, while thrust forces are transferred from the plate to the beam and the drawbar via the parts and seams without loading the coupling, its main shaft and the latter's bearing. | ||||||
| 199 | SUBSURFACE CHILLS TO IMPROVE RAILCAR KNUCKLE FORMATION | US15057855 | 2016-03-01 | US20160207103A1 | 2016-07-21 | Jerry R. Smerecky; F. Andrew Nibouar; Noland Brooks; Nick Salamasick |
| A method for manufacturing a railcar coupler knuckle includes, before casting, positioning an external chill within a cope mold portion and a drag mold portion offset from and adjacent internal walls of a pulling face and a throat of the cope and drag mold portions, thus producing a casting with reduced micro-shrinkage in at least the throat, a high-stress section of the casting. Use of subsurface chills produces an improved surface with fewer inclusions when compared to an equivalent surface produced in a process without use of a subsurface chill. The external chill may be a cone chill of a larger size to improve cooling and solidification at and below the surface. The external chill may also be a cylindrical and/or oblong chill with a tapered design that may correspond to the internal walls of the cope and drag mold portions between the pulling face and the throat. | ||||||
| 200 | Railcar Coupler Knuckle Cores and Knuckles Produced by Said Cores | US14880897 | 2015-10-12 | US20160031457A1 | 2016-02-04 | F. Andrew Nibouar; Jerry R. Smerecky; Kelly Day; Vaughn Makary; Nick Salamasick |
| A knuckle may include a throat portion having a throat side wall with at least three sections, a first section closest to the knuckle tail, a third section closest to the knuckle pulling face, and a second section between said first and third sections. The wall thickness of said first section may be less than 10% different than the wall thickness of said second section. The throat portion may also include a tail stop side wall with at least three sections, a first section closest to the knuckle tail, a third section closest to the knuckle pulling face, and a second section between said first and third sections. The wall thickness of said first section may be less than 10% different than the wall thickness of said second section. | ||||||
