Abstract: A biparting transit vehicle door system operator. The operator includes a base for attachment to the mass transit vehicle and a motive power source connected to a transmission having an output power shaft. Such operator further includes a teeter plate having a shaft engaging portion for engaging the shaft. The shaft has a teeter plate engaging portion for engaging the operator teeter plate. A thrust bearing is in mechanical contact with a hub portion of the teeter plate and a spring is in mechanical contact with the thrust bearing to exert a first axial thrust thereon. The thrust bearing communicating the first axial thrust to the teeter plate so that the shaft engaging portion of the teeter plate engages the teeter plate engaging portion of the shaft. The operator includes a release member having mechanical contact with the hub portion of the teeter plate for exerting a second axial thrust on the teeter plate. The second axial thrust being opposed to the first axial thrust so that the teeter plate may be disengaged from the shaft by the release member. A pair of drive rod pivots are attached to the teeter plate. Such pair of drive rod pivots are connected to a pair of drive rods for opening and closing the pair of biparting doors.

Abstract translation: 一个两用运输车门系统操作员。 操作者包括用于附接到公共交通车辆的基座和连接到具有输出动力轴的变速器的动力源。 这种操作者还包括具有用于接合轴的轴接合部分的跷跷板。 轴具有用于接合操作员跷板的跷板接合部分。 止推轴承与跷跷板的轮毂部分机械接触，并且弹簧与推力轴承机械接触以在其上施加第一轴向推力。 推力轴承将第一轴向推力传递到摇摆板，使得跷跷板的轴接合部分接合轴的跷板接合部分。 操作者包括具有与跷跷板的轮毂部分机械接触的释放构件，用于在踩踏板上施加第二轴向推力。 所述第二轴向推力与所述第一轴向推力相对，使得所述摇摆板可以通过所述释放构件从所述轴脱离。 一对驱动杆枢轴连接在跷跷板上。 这对驱动杆枢轴连接到一对驱动杆，用于打开和关闭一对双门。
