Description

一种轻轨车辆转向架 技术领域
本发明属于轨道交通领域，具体涉及一种轻轨车辆转向架。
背景技术
一般的地铁转向架，均采用无摇枕的空气弹簧结构。现代的轻轨车辆为了通过更小的曲线半径，往往采用空气簧配合摇枕结构，以适应转向架与车体之间产生较大的转角。由于需要安装摇枕，使得转向架空间设备安装空间受限，具体表现在如下几个方面：
1.传统的轻轨车辆转向架的牵引装置一般安装于横梁位置，或者在侧梁上的较高位置。牵引装置若安装在横梁处，会导致占用横梁空间，使得横梁上的其他部件安装困难。而安装在侧梁上的形式牵引点高，黏着利用率低。
2.磁轨制动器为悬伸式安装，通过固定在横梁上的一个L形座，实现磁轨制动器安装于轨面正上方，L形座的设置也会占用横梁空间，结构复杂且结构强度难以保证。
3.传统的轻轨车辆转向架的电机安装座和横向止挡都是独立的分别设置于横梁上，结构散，占用横梁空间大。
4.由于安装摇枕后导致转向架空间设备安装空间受限，因此难以设计制动夹钳的安装位置，更难以布置磁轨制动装置。以往的磁轨止挡一般为悬伸式安装座，结构复杂且结构强度难以保证。
另外，现有的轻轨车辆基本不设置整体起吊结构，需要整体起吊时，采用钢绳将车体与构架捆绑吊装，费时费力。
另外，对本案中所提到的方向词汇进行定义，在轨道车辆领域中，技术人 员通常认定的方向有三种：
垂向：竖直垂直于轨面的方向。
纵向：沿着轨道的方向。
横向：水平垂直于轨道的方向。
构架中心轴是穿过构架中心的沿垂向的轴线。
关于中心轴旋转对称是指一个物体绕着中心轴旋转一定角度α后与另一个物体重合。
相关现有技术：CN106809233A；CN201249778Y。
发明内容
针对上述问题，本发明旨在提供一种可实现轻轨车辆低位牵引，且横梁空间更优化的转向架。
为了解决上述技术问题，本发明采用的技术方案是：
一种轻轨车辆转向架，包括构架，所述构架包括侧梁、垂直于侧梁中部的横梁，侧梁中部设置有凹陷区域，在横梁顶部设有摇枕，所述横梁由两根沿纵向间隔设置的管体组成，在每一根管体两端均设有连接座,管体两端通过连接座与侧梁固定连接；所述轻轨车辆转向架还包括分别安装于轮对轴颈上的轴箱，在两个轴箱上向内侧延伸设有悬臂座，在两个悬臂座上吊装有磁轨制动器；在磁轨制动器顶部设有垂向导杆，在每个连接座的一侧均安装有限位座，所述限位座位于磁轨制动器两端的正上方，限位座上开有贯通的导向孔，所述垂向导杆插入导向孔内；所述磁轨制动器位于管体的正下方。
上述方案中，通过对摇枕结构的改进以及牵引点位置改变至侧梁的凹陷区域，实现了轻轨车辆的低位牵引，提高了车辆粘着利用率，而且不占用横梁 空间。
进一步的，所述侧梁包括上盖板、下盖板、以及两侧板，四块板合围构成箱型侧梁，且侧梁的上盖板和下盖板的两侧边沿处横向延伸有裙边；在上盖板和下盖板的裙边上对应拉杆安装座的安装位置处横向开有凹槽，所述拉杆安装座顶部卡入上盖板的凹槽并固定，拉杆安装座底部卡入下盖板的凹槽并固定，且拉杆安装座的顶部与上盖板顶部平齐、拉杆安装座的底部与下盖板底部平齐。
在每个侧梁中部凹陷区域的外侧面上固定连接有拉杆安装座，在摇枕两端分别沿垂向向下延伸设有悬臂，在每个悬臂与其同侧的拉杆安装座之间均设有拉杆，所述拉杆的一端安装于拉杆安装座、该拉杆的另一端与悬臂下端固定连接；由悬臂、拉杆安装座、拉杆三者装配连接的两套结构关于构架的中心轴旋转对称，且旋转角度α为180度。
上述进一步改进的方案中，通过开设凹槽使得拉杆安装座与侧梁连接的曲面增多，将直焊缝变为曲线焊缝，增加了焊缝长度，提高了连接强度。
更进一步的，在侧梁外侧面上横向伸出设有挡块；在悬臂上沿纵向设有支撑块，所述挡块位于支撑块正上方，挡块与支撑块之间留有间隙。
上述结构的设计是为了方便吊装，车辆平常运行时，挡块与支撑块之间存在微小的间隙，当需要整体起吊时，起吊点位于车体，车体的起吊会带动摇枕向上运动，从而使得支撑块与挡块抵接，在支撑块的支撑下，将与挡块固定的构架吊起。这种结构的设计充分利用了改进后的摇枕结构，是更进一步创造思维的成果，结构紧凑，设计巧妙，提高了轻轨车辆的起吊效率。
进一步的，所述连接座上开有腰型孔，腰型孔长轴方向沿纵向，所述限位 座与连接座之间通过插入腰型孔的紧固件紧固。紧固件可以是螺栓。
采用限位座安装过渡可方便调整安装时的间隙。
具体的，所述横梁由两根沿纵向间隔设置的管体组成。所谓纵向间隔是指两根管的布置方向，对于单根横梁而言，是横向延伸的。
进一步的，在两根管体上设有横跨两根管体、并与两根管体同时形成抱箍式固定连接的跨座，所述跨座的横向两侧面均为横向止挡接触面，跨座的纵向两端面为电机安装面。
上述跨座将电机安装座和横向止挡的功能集成到一起，既可以充当横向止挡又可以用于安装电机，结构紧凑，相对于背景技术中所提到的现有技术节省了横梁的空间，为其它部件的安装提供了便利。
优选地，本发明的所述构架为H型构架。
本发明采用紧凑型设计，将牵引拉杆安装座设置在侧梁中部外侧，在保证了牵引拉杆安装座足够的结构强度同时充分利用了设计空间。巧妙地在横梁与侧梁连接座上设置磁轨止挡装置，合理地利用了空间，并且保证了磁轨止挡装置的结构强度。
本发明的显著效果是：
1.通过对摇枕结构的改进以及牵引点位置改变至侧梁的凹陷区域，实现了轻轨车辆的低位牵引，提高了车辆粘着利用率。通过开设凹槽使得拉杆安装座与侧梁连接的曲面增多，将直焊缝变为曲线焊缝，增加了焊缝长度，提高了连接强度。
2.巧妙的设计了起吊结构，提高了轻轨车辆的起吊效率。
3.电机安装座和横向止挡功能集成在一起，以及重新设计磁轨制动结构的 安装方式和安装位置等一系列改进，节省了更多的横梁空间，转向架结构更加紧凑，其它设备的安装也更加方便。
