摘要： A lower lockpin rotation shaft assembly includes a lower lockpin rotation shaft body, an outer end portion thereof having a first coupler lifting bar hole, an intermediate portion thereof having a connecting key; and a lower lockpin rotation shaft bush, an outer end portion of the lower lockpin rotation shaft bush having a second coupler lifting bar hole, and an inner end portion of the lower lockpin rotation shaft bush being operatively connected to an inner end portion of the lower lockpin rotation shaft body. Further, the present invention further provides a double-side operating coupler and a coupler draft gear having the above lower lockpin rotation shaft assembly. The coupler draft gear further includes two coupler lifting bars and two coupler lifting bar seats. Each of the coupler lifting bars is inserted in a keyhole-shaped through hole of corresponding coupler lifting bar seat, and the coupler lifting bar has a restrained segment at a fitted portion of the coupler lifting bar with the coupler lifting bar seat. Coupler heads of the two coupler lifting bar are inserted through the keyhole-shaped through holes of the two coupler lifting bar seats and then coupled with the first coupler lifting bar hole and the second coupler lifting bar hole of the double-side operating coupler. There is a gap between the restrained segment of each coupler lifting bar and walls of the rectangular hole of the keyhole-shaped through hole.

摘要： An automatic coupler for railway and other vehicles which includes an outer housing carried by the vehicle and formed of a plurality of welded metal plates, with a spring urged coupling hook mounted therein for horizontal pivotal movement for engagement with the hook of a coupler mounted on an adjacent vehicle. The hook is unlocked by a cam bearing on it and the opposed interengaged hook from the adjacent vehicle, which cam may be operated manually or automatically. The foregoing abstract is not to be taken as limiting the scope of invention, and in order to understand the full nature and extent of the technical disclosure of this patent, reference must be made to the accompanying drawings and the following detailed description.

摘要：【課題】連結錠の表面及び/又は錠室の壁面におけるかじりきずの発生を低減することができる鉄道車両用の連結器を提供する。【解決手段】連結器(10)は、鉄道車両を他の鉄道車両に連結する。連結器(10)は、連結器体(11)と、連結錠レバー(13)と、連結錠(12)と、を備える。連結器体(11)は、連結面(111)と、案内部(112)と、を含む。案内部(112)は、錠室(1120)を有する。連結錠(12)は、その水平断面視で半円状をなす。連結錠(12)には、鉄道車両同士が分割される際、連結錠レバー(13)から荷重が負荷される。これにより、連結錠(12)は、錠室(1120)の壁面(1120a)に押し付けられて他の鉄道車両側に回転する。壁面(1120a)のうち、連結状態において連結錠(12)の先端部(123)が対向する位置から他の鉄道車両側の領域には、凹部(1120c)が形成されている。【選択図】図3
