Description

一种纵向驱动的轴箱内置式转向架 技术领域
本发明涉及轨道机车转向架，特别是一种纵向驱动的轴箱内置式转向架。
背景技术
目前，世界上轨道车辆使用的非受电弓式受流的布置方式主要有三种，分别为上磨式、下磨式和侧面接触式。侧面接触式的接触轨轨头端面朝向走行轨，接触靴从侧面压向接触轨，也称为侧面受流，在英国伦敦地铁，意大利米兰地铁及马来西亚轻轨线上均有应用。采用侧面受流的线路，接触轨安装位置比轨面高，车辆的下部限界受到挤压，传统的轴箱外置式的转向架不能满足限界的要求。而轴箱内置式的转向架由于其轴箱安装在车轮内侧，占用空间较小的特点，可以适用于这样的极小限界。
但由于轴箱安装在车轮内侧，转向架中间的空间很小，传统的电机横向布置的方式受体积限制，无法安装大半径的轴盘制动装置，且制动夹钳仅能安装在振动条件恶劣的转向架端部，而安装轮盘制动或踏面制动装置时转向架的重量大幅增加，难以实现更高的轻量化水平。采用电机纵向布置方案的转向架虽然能布置轴盘制动装置，但由于电机安装在转向架中部，难以布置牵引拉杆，常见的解决方案为在电机上方增加摇枕，将摇枕与构架通过牵引拉杆连接起来。为适应现代轨道交通的轻量化，高运行性能的要求，急需发展一种能采用轴盘制动方式的无摇枕的纵向驱动的轴箱内置式转向架。
发明内容
本发明所要解决的技术问题是，针对现有技术不足，提供一种电机纵向布置，采用轴盘制动方式的轻量化无摇枕的纵向驱动的轴箱内置式转向架。
为解决上述技术问题，本发明采用的技术方案是：一种纵向驱动的轴箱内置式转向架，包括前、后两端分别设有车轴的构架，两根车轴的两端分别安装车轮，所述构架经轴箱安装在车轴上，且所述构架和轴箱都布置在车轮内侧，所述构架包括平行设置的两根侧梁，两根侧梁的中部平行设置第一、二横梁，所述构架和轴箱都布置在车轮内侧，所述两根侧梁上分别通过电机吊挂座安装有一牵引电机，并使两牵引电机位于第一、二横梁之间，且两牵引电机的一侧分别通过电机吊挂座安装在构架的侧梁上，另一侧连接成一体，并使两牵引电机的输出轴与车轴垂直，同时将两牵引电机的输出轴通过联轴节和安装于侧梁上的齿轮箱连接车轴。
上述方案中，一根车轴上仅布置一轴盘制动盘，所述轴盘制动盘与位于构架上的制动夹钳相配合安装，这样不仅保证了制动能力，而且减小了制动装置的数量和重量，相比于轮盘制动形式降低了簧下质量，减小了对线路的冲击。
上述方案中，所述第一横梁上设有牵引座，且所述第一横梁经牵引座直接固定连接牵引拉杆的一端，牵引拉杆的另一端与车体固定连接，这样省去了摇枕，极大地减小了转向架的质量，也简化了转向架的维护项点和难度。
上述方案中，所述两牵引电机的一侧通过螺栓连接成一体，另一侧置于所述侧梁底部，并通过螺栓、螺母结构与构架侧梁连接成一体，且螺栓的轴向垂直于地面。这样拆卸电机时不需要吊起车体，只需要拆下侧梁下部的紧固件就可以直接将电机从转向架上落下，极大简化了电机拆装的设备需求和操作难度。
上述方案中，所述轴箱通过一系悬挂装置与所述构架连接，所述构架上安装有二系悬挂装置、横向止档、受流器、抗侧滚装置及所述制动夹钳。
上述方案中，所述构架侧梁上设有齿轮箱吊挂座，所述齿轮箱的一侧通过齿轮箱吊挂座与构架侧梁固定连接，且所述齿轮箱一端通过联轴器与牵引电机输出轴连接，另一端与所述车轴固定连接。所述第一、二横梁上分别设有齿轮箱防脱落座，所述齿轮箱安装在所述齿轮箱吊挂座和齿轮箱防脱落座上，以使齿轮箱的安装更为牢固可靠。
上述方案中，所述轴箱内集成有接地装置或测速齿轮，且所述轴箱上设有镟轮工艺孔，这样，车轴的轴端不设设备，也不需要在构架上设置稳定杆连接并稳定轴端设备，避免了轮对在非常恶劣的振动条件下造成稳定杆断裂的风险。
与现有技术相比，本发明所具有的优点在于：
1、本发明将轴箱和构架侧梁都布置于轮对内侧，减小了转向架整体横向尺寸，可以适用于侧面受流的极小车辆下部限界，且本发明电机纵向布置(即牵引电机的输出轴与车轴垂直)在转向架中部，在构架内侧横向空间受限的情况下，充分利用了纵向空间，增加了电机可用空间，提高了电机的功率和牵引性能。电机纵向布置的结构还释放了轴盘制动盘的纵向空间，在轴距不变的情况下增大了轴盘制动盘的尺寸，增加了制动夹钳的制动半径，在同等夹紧力的情况下提高了制动能力，因而可以在每个轮对上仅设置一个轴盘制动单元，减小了制动装置的数量和重量，且相比于轮盘制动形式降低了簧下质量，减小了对线路的冲击。此外制动夹钳可以安装在振动条件更好的横梁上。
2、本发明的轴箱布置于轮对内侧，降低了转向架的扭转刚度，提高了曲线通过能力。
3、本发明转向架为无摇枕结构，直接设置单牵引拉杆进行传动，极大地减小了转向架的质量，也简化了转向架的维护项点和难度。
4、本发明利用第一、二横梁间距较大的特点，将牵引座集成在第一横梁上，用长牵引 拉杆适应车体高度变化并避开中部的牵引电机，同时使牵引点的高度大为降低，提高了牵引时的粘着利用率。

该构架3由两根侧梁20和第一、二横梁23、26连接而成。两根构架侧梁20上设有齿轮箱吊挂座24、电机吊挂座21，第一横梁23上设有牵引座22，且第一、二横梁23、26上分别设有齿轮箱防脱落座27、制动夹钳安装座25。位于第一、二横梁23、26之间的两根构架侧梁20分别通过电机吊挂座21安装有一牵引电机13，并使两牵引电机13的输出轴与车轴2垂直，两牵引电机13的相对侧通过螺栓连接成一体，且两牵引电机13的输出轴通过联轴节16和通过齿轮箱吊挂座24连接在侧梁20上的齿轮箱17连接车轴，这样，两个牵引电机13安装在构架3的中间，通过联轴节16将转矩传递给交直传动的齿轮箱17。每根车轴2上仅布置一轴盘制动盘18，第一、二横梁23、26上的制动夹钳安装座25上分别安装有制动夹钳9，两根车轴2上的轴盘制动盘18分别与第一、二横梁23、26上的制动夹钳9相对安装，实现车辆的制动。第一横梁23通过牵引座22固定连接牵引拉杆14的一端，牵引拉杆14的另一端固定在车体牵引座上，从而实现无摇枕传动。各轴箱12分别通过一系悬挂装置10与构 架3连接，构架3上还安装有二系悬挂装置7、横向止档11、受流器4、抗侧滚装置6等设备。
由图5可知，一轮对的两轴箱12布置在车轮1内侧，在两个轴箱12的中间布置轴盘制动盘18和齿轮箱17。轴箱12可以集成接地装置28、29或测速齿轮30，并设有轴箱镟轮工艺孔32。车轴2上也设有轮对镟轮工艺孔33。
