    摘要： An apparatus for mounting an attachment structure (such as an EOT) to a railroad coupler includes a base, a locking member (J-hook), a bolt and one or more spring elements. The base includes a mounting portion for the attachment structure and a sleeve insertable through the attachment structure. The base, the J-hook and the bolt cooperate such that the J-hook is rotated from an unlocked position to a locked position by torque applied via the bolt head. Consequently, the J-hook shaft is pulled inside the sleeve and the J-hook aligns with a clamp face of the base to clamp a portion of the coupler therebetween. Responsive to the applied torque, the one or more spring elements are compressed to allow mechanical engagement between a first surface and a second surface, producing a mechanical torque opposing the applied torque, which reduces axial forces on the J-hook.

    摘要： A railroad coupler knuckler meets AAR contour requirements and it includes unique external weight reducing features that strategically reduce weight without compromising strength or fatigue life. The design of the railroad knuckle of the present invention allows for formation of the knuckle through forging or coreless casting techniques and thus allows for the use of a better grade of steel compared to AAR Grade E and such forged or cast knuckle will yield much higher fatigue life compared to cast knuckles.

    摘要： 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.

    摘要： 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.

    摘要： 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.
