Electric device of passenger car split sliding plug door
The invention relates to an electric device of a passenger car split sliding plug door. The electric device comprises a rail box fixed to a passenger car body and a sliding plug driving trolley installed in the rail box, the rail box is provided with two sliding plug guide rails, and a guide sliding way is arranged in the middle of the rail box; a trolley body of the sliding plug driving trolley is composed of a left trolley body end plate, a right trolley body end plate, a top cross beam and a bottom guide bar, a transmission lead screw is arranged above the bottom guide bar, a left-hand thread section is arranged at the left portion of the transmission lead screw, a right-hand thread section is arranged at the right portion of the transmission lead screw, a left-hand nut assembly is installed at the left-hand thread section, and a right-hand nut assembly is installed at the right-hand thread section; and the left portion of the bottom guide bar is sleeved with a left door carrying frame, and the right portion of the bottom guide bar is sleeved with a right door carrying frame. According to the electric device, the size and the weight of the sliding plug driving trolley are optimized, the axial positions of the left door carrying frame and the right door carrying frame can be accurately adjusted, and impact and noise generated in the running process of the sliding plug drivingtrolley are eliminated.
本发明涉及一种客车对开塞拉门电动装置，包括与客车车体固定的轨道箱、安装在该轨道箱内的塞拉驱动小车，轨道箱设置两条塞拉导轨，轨道箱的中部设置一条导向滑道，塞拉驱动小车的车体由左右两个车体端板、一个顶部横梁、一条底部导杠构成，底部导杠上方设置一条传动丝杠，该传动丝杠左部设置左旋螺纹段，其右部设置右旋螺纹段，左旋螺纹段上安装左旋螺母组件，右旋螺纹段上安装右旋螺母组件，底部导杠左部套装左携门架，底部导杠右部套装右携门架。本发明优化了塞拉驱动小车的体积和重量，能够精准调节左、右携门架的轴向位置，消除了塞拉驱动小车运行中的冲击和噪音。
