下面将参考附图并结合实施例来详细说明本公开。
参照附图详细描述根据本公开实施例的转向架总成1000。如图1-图12所示，转向架总成1000包括转向架构架100、牵引机构200、走行轮300、导向轮400、稳定轮500、电动总成600和悬挂系统700。
转向架构架100具有用于跨坐在轨道梁2000上的轨道凹部，牵引机构200、走行轮300、导向轮400、稳定轮500、电动总成600和悬挂系统700均安装于转向架构架100上，悬挂系统700支撑在转向架构架100与跨座式单轨车辆的车体之间，电动总成600用于驱动走行轮300沿轨道梁2000的行走表面运动，牵引机构200连接在转向架构架100与跨座式单轨车辆的车体之间，牵引机构200用于将走行轮300的动力传递给车体，导向轮400和稳定轮500均夹持轨道梁2000的侧壁。
下面参考附图描述根据本公开实施例的走行轮300、导向轮400和稳定轮500。
如图1和图12，走行轮300沿轨道梁2000的行走表面(上表面)行驶，走行轮300至少为一个，走行轮300的转动轴线与轨道梁2000的行走表面平行。在本公开的一些实施例中，走行轮300可以包括橡胶轮胎，这样跨座式单轨车辆的抗振性更好。当然，走行轮300也可以为钢轮。
如图1、图11和图12，转向架总成1000可以具有两对导向轮400，两对导向轮400沿前后方向间隔开，每对导向轮400均包括两个导向轮400，且这两个导向轮400关于轨道梁2000对称设置，这两个导向轮400分别与轨道梁2000的一个侧壁接触。同一对导向轮400中的两个导向轮400的转动轴线到走行轮300的转动轴线的距离相等。
稳定轮500至少为两个，两个稳定轮500关于轨道梁2000对称设置，且这两个稳定轮500分别与轨道梁2000的一个侧壁接触，每个稳定轮500的转动轴线均与走行轮300的转动轴线垂直。
下面参考图2-图6描述根据本公开实施例的牵引机构200。如图2-图6所示，牵引机构200包括牵引架210和牵引销组件220，牵引架210与转向架构架100的构架本体110相连，牵引销组件220与牵引架210相连，且牵引销组件220适于与车体相连。牵引力通过转向架构架100、牵引架210、牵引销组件220和车体依次传递。
首先参考图2描述根据本公开实施例的牵引架210。如图2所示，牵引架210包括顶壁211、侧壁212和固定座。
其中，设有两个侧壁212，两个侧壁212的上端分别与顶壁211的前端和顶壁211的后端相连，每个侧壁212的下端均设有多个固定座，固定座用于与构架本体110相连。连接在 两个侧壁212下方的多个固定座分别与构架本体110的前臂和后臂相连，即一个侧壁212下方的多个固定座与构架本体110的前臂相连，而另一个侧壁212下方的多个固定座与构架本体110的后臂相连，以使牵引架210适于沿前后方向跨坐在转向架构架100上，这样牵引架210在前后方向上的刚度大于牵引架210在左右方向上的刚度，有助于牵引架210传递前后方向上的牵引力。
参考图2，位于同一个侧壁212下端的多个固定座包括第一固定座213和第二固定座214，第一固定座213和第二固定座214沿左右方向间隔布置，构架本体110的前臂和后臂中每一个的左半段和右半段的高度不一致，左半段和右半段通过弧形段连接，这样转向架构架100的强度更高，并且第一固定座213的底面和第二固定座214的底面位于不同水平面，以与转向架构架100的构架本体110配合。由此，牵引架210的安装强度高，与转向架构架100配合更好，有助于更好地传递牵引力。
根据本公开实施例的牵引架210，通过设置处于不同高度的多个固定座，有助于牵引架210与转向架构架100的配合，牵引架210的强度大，可以承载较大的牵引力，牵引过程稳定可靠。
牵引架210的侧壁212和顶壁211可以一起形成为拱形结构，牵引架210适于罩设在走行轮300的上方，顶壁211可以为平板状，顶壁211适于与车体相连，侧壁212可以为弧形。在如图2所示的实施例中，侧壁212包括多个依次相连的弧形段，侧壁212的宽度从上到下逐步增大，这样牵引架210的强度更大，牵引稳定性更高。
侧壁212的左右两侧的边沿可以均设有加强筋212a，以增强侧壁212的强度。以侧壁212的右侧为例，侧壁212右侧的前边沿和后边沿分别沿横向向外(即向右)延伸以形成加强筋212a，侧壁212的左侧的边沿的加强筋212a的形成方式与右侧相同。
参考图2，第一固定座213与对应的第二固定座214之间可以镂空以形成减重孔215，由此，在不影响牵引力传递的基础上，可以降低牵引架210的重量，有助于提升牵引架210的轻量化水准，减重孔215的侧壁与减重孔215的顶壁之间可以具有弧形的过渡角，以防止减重孔215的侧壁与减重孔215的顶壁的连接处产生应力集中，由此牵引架210的使用耐久性更高。
第一固定座213可以包括第一连接臂213a和第一安装板213b，第一连接臂213a与对应的侧壁212相连，第一安装板213b与第一连接臂213a相连。参考图2，第一连接臂213a的上端与对应的侧壁212相连，第一连接臂213a的下端与对应的第一安装板213b相连。在本公开的一些实施例中，第一连接臂213a与第一安装板213b可以焊接相连。此外，第一安装板213b适于与转向架构架100相连。例如，第一安装板213b上可以设有多个安装孔，螺纹紧固件贯穿该安装孔与转向架构架100的构架本体110相连，进而将第一安装板213b连接至转向架构架100。
第二固定座214可以包括第二连接臂214a和第二安装板214b，第二连接臂214a与对应 的侧壁212相连，第二安装板214b与第二连接臂214a相连。参考图2，第二连接臂214a的上端与对应的侧壁212相连，第二连接臂214a的下端与对应的第二安装板214b相连。在本公开的一些实施例中，第二连接臂214a与第二安装板214b可以焊接相连。此外，第二安装板214b适于与转向架构架100相连。例如，第二安装板214b上可以设有多个安装孔，螺纹紧固件贯穿该安装孔与转向架构架100的构架本体110相连，进而将第二安装板214b连接至转向架构架100。
在本公开的一些实施例中，第一连接臂213a、第二连接臂214a分别与对应的侧壁212一体成型，即第一连接臂213a与对应的侧壁212一体成型，第二连接臂214a也与对应的侧壁212一体成型。此外，加强筋212a可以从侧壁212的边沿一直延伸至第一连接臂213a的外侧边沿(即左侧边沿)、第二连接臂214a的外侧边沿(即右侧边沿)以及顶壁211的下侧边沿。
本公开实施例还公开了一种转向架总成1000，根据本公开实施例的转向架总成1000设置有上述任一实施例所描述的牵引架210，牵引架210与转向架构架100相连。根据本公开实施例的转向架总成1000的牵引力传递稳定，可以承载较大的驱动力。
本公开实施例还公开了一种跨座式单轨车辆，根据本公开实施例的跨座式单轨车辆设置有上述任一实施例描述的转向架总成1000，转向架总成1000的牵引架210与跨座式单轨车辆的车体相连。根据本公开实施例的跨座式单轨车辆，牵引力的传递稳定。
下面参考图2-图6描述根据本公开实施例的牵引销组件220。
如图2-图4所示，在本公开的一些实施例中，牵引销组件220包括销轴221和车体连接件，销轴221与牵引架210和车体连接件相连，车体连接件适于与车体相连，且车体连接件设置成其在前后方向上的刚度大于其在左右方向上的刚度。
可以理解的是，在牵引机构200的工作过程中，牵引力主要是沿前后方向传递，牵引力从牵引架210通过销轴221与车体连接件传递到车体，通过将车体连接件设置成其在前后方向上的刚度大于其在左右方向上的刚度，可以防止车体连接件损坏，牵引更稳定，避免转向时出现应力集中。
参考图3和图4，车体连接件可以包括销套安装座和销套222。销套222与销套安装座相连，销套安装座适于与车体连接。销套安装座可以包括固定筒223和安装板224，安装板224与固定筒223相连，固定筒223可以套设在销套222外，且固定筒223与销套222之间填充有缓冲件225。销轴221的一端固定连接在牵引架210的顶壁211上，比如销轴221可以与牵引架210的顶壁211焊接相连，销套222套设在销轴221外，且销套222可以与销轴221过盈配合，这样销套222与销轴221之间不易产生磨损且无异响。
安装板224适于与车体连接，比如安装板224可以通过螺纹紧固件与车体相连。安装板224可以沿固定筒223的周壁环绕固定筒223，即固定筒223可以贯穿安装板224，且固定筒223的位于安装板224上方的部分的高度小于位于安装板224下方的部分的高度。在将车 体连接件与车体连接时，固定筒223的位于安装板224上方的部分可以与车体上的凹陷部配合，以实现安装板224与车体之间的定位。
牵引机构200工作时，牵引力在牵引架210、销轴221、销套222、缓冲件225、固定筒223和安装板224之间顺次传递，然后传递到车体以实现对车体的牵引，牵引力传递时的噪音小，牵引稳定，且可以承载较大的牵引力。
在如图4所示的实施例中，固定筒223可以具有椭圆形水平截面，且椭圆形水平截面的长轴沿前后方向定向，椭圆形水平截面的短轴沿左右方向定向，缓冲件225具有椭圆形水平截面，且椭圆形水平截面的长轴沿前后方向定向，椭圆形水平截面的短轴沿左右方向定向。这样，可以使车体连接件在前后方向上的刚度大于其在左右方向上的刚度，且缓冲件225在前后方向上可以吸收更多的振动，因此牵引机构200的抗振性能更好。
在本公开的一些实施例中，缓冲件225内可以具有缝隙226，缝隙226可以位于销套222的左侧或右侧。如图4所示，缝隙226可以为两个，两个缝隙226可以分别位于销套222的左侧与右侧，两个缝隙226可以关于一个对称面对称设置，该对称面的法线沿左右方向定向，且销套222的中轴线在该对称面内。
可以理解的是，在牵引机构200的工作过程中，牵引力主要是沿前后方向传递，振动冲击也主要来自于前后方向，通过在销套222的左侧与右侧设置缝隙226，可以减轻牵引机构200的质量，降低车体连接件的左右方向上的刚度以及增加车体连接件的左右方向上的连接强度。
参考图4，缝隙226的水平截面可以为拱形，缝隙226包括沿前后方向依次相连的第一段226a、第二段226b和第三段226c。第二段226b为矩形，且矩形第二段226b的长边正对销套222。第一段226a为从矩形第二段226b的短边延伸至缓冲件225边缘的弧形段，且第一段226a与第三段226c对称设置。
在本公开的一些实施例中，缓冲件225可以包括多个子缓冲件。如图4所示，缓冲件225被两个相互平行的分割面225e及销套222分割为四个子缓冲件225a、225b、225c、225d，分割面225e的法线沿前后方向定向，且两个分割面225e均与销套222相交。
子缓冲件225a与子缓冲件225c对称设置，子缓冲件225b与子缓冲件225d对称设置，子缓冲件225b和子缓冲件225d位于两个分割面225e之间。
两个缝隙226分别将子缓冲件225b和子缓冲件225d分隔为两部分，两部分中靠近销套222的部分与销套222固定连接，两部分中靠近固定筒223的部分与固定筒223固定连接。比如缓冲件225可以为橡胶件，销套222和固定筒223可以为金属件，缓冲件225可以与销套222及固定筒223分别硫化连接。这样可以防止子缓冲件225b和子缓冲件225d的被缝隙226分隔成的两部分沿左右方向晃动。
如图5-图6所示，在本公开的另一些实施例中，牵引销组件220可以包括销轴221，销轴221与牵引架210的顶壁211相连。例如，牵引架210的顶壁211可以具有安装孔，销轴 221的下端可以具有螺纹段221b，销轴221贯穿安装孔，且螺纹段221b通过螺母229a固定。螺母229a可以位于牵引架210的顶壁211的下方，且螺母229a与牵引架210的顶壁211之间还可以夹设有垫片229b。销轴221的上端可以具有法兰221a，法兰221a适于与车体通过螺纹紧固件连接。
在本公开的一些实施例中，牵引销组件220还可以包括上减振垫228a和下减振垫228b，上减振垫228a可以夹设在法兰221a与牵引架210的顶壁211的上表面之间，下减振垫228b可以夹设在螺母229a与顶壁211的下表面之间。具体地，下减振垫228b可以夹设在顶壁211的下表面与垫片229b之间。在本公开的一些实施例中，上减振垫228a和下减振垫228b可以均为橡胶件。
牵引销组件220还可以包括衬套227，衬套227套设在销轴221外，衬套227的长度可以与牵引架210的顶壁211的厚度相同。衬套227可以包括多层，例如外层钢套、内层钢套和缓冲套。缓冲套位于外层钢套与内层钢套之间，缓冲套可以为橡胶件。外层钢套可以与牵引架210的顶壁211上的安装孔过盈配合，内层钢套套设在销轴221外，且内层钢套可以与销轴221过盈配合。
根据本公开实施例的牵引机构200，具有根据上述任一实施例的牵引架210和根据上述任一实施例的牵引销组件220，这样牵引机构200的强度大，可以承载较大的牵引力，牵引过程稳定可靠，噪音小。
本公开实施例还公开了一种转向架总成1000，根据本公开实施例的转向架总成1000设置有上述任一实施例描述的牵引机构200，牵引机构200与转向架总成1000的转向架构架100相连。根据本公开实施例的转向架总成1000的牵引力传递稳定，可以承载较大的驱动力。
本公开实施例还公开了一种跨座式单轨车辆，根据本公开实施例的跨座式单轨车辆设置有上述任一实施例描述的转向架总成1000，转向架总成1000的牵引机构200与跨座式单轨车辆的车体相连。根据本公开实施例的跨座式单轨车辆的牵引力传递稳定。
下面参考图1和图7-图9描述根据本公开实施例的电动总成600。
参考图1和图7，电动总成600安装在转向架构架100上，且电动总成600包括牵引电机610、齿轮减速器620和行星式轮边减速器630。牵引电机610与齿轮减速器620的输入轴相连，齿轮减速器620的输出轴与行星式轮边减速器630的输入端相连，行星式轮边减速器630的输出端与走行轮300的轮毂相连。电动总成600可以从轨道梁2000上的导电轨2001取电。
也就是说，电动总成600至少包括两级减速机构，电动总成600的传动比大，因此在一定范围内可以采用高转速的牵引电机610，所以电动总成600的能量利用率高，有利于节能环保。
根据本公开实施例的转向架总成1000采用牵引电机610、齿轮减速器620，行星式轮边 减速器630以及轮毂等合装一体的驱动方案，整体结构简单，占用空间少，可以实现低地板结构，重量轻，能量利用率高，有利于节能环保。
在本公开的一些实施例中，电动总成600可以布置在转向架构架100的内侧，且牵引电机610可以横置，即牵引电机610的电机轴的轴线沿横向(左右方向)定向。这样，转向架总成1000的结构紧凑，横向及纵向的尺寸较小。牵引电机610可以与齿轮减速器620的箱体相连，齿轮减速器620的箱体与转向架构架100相连。例如，转向架构架100上可以设有电机安装支架，齿轮减速器620的箱体可以通过螺纹紧固件与电机安装支架连接。电机安装支架可以为两个，两个电机安装支架沿前后方向间隔开以夹持电动总成600。电机安装支架可以包括连接板和支撑辐板，连接板与齿轮减速器620的箱体螺纹连接，支撑辐板可以构造为三角形，且支撑辐板的一侧与连接板焊接相连，另一侧与转向架构架100焊接相连。
在本公开的一些实施例中，电动总成600还可以包括制动器640，制动器640可以布置在牵引电机610与走行轮300之间。如图7所示，制动器640安装在齿轮减速器620与走行轮300的轮毂之间。这样，无需在转向架构架100上单独设置制动器640的安装位，可以减轻转向架总成1000的重量，显著提高空间利用率，为其它零部件的布置提供了空间。
参考图9，制动器640包括制动盘641、制动钳642和制动驱动单元643，其中，制动盘641可以与走行轮300的轮毂相连，比如制动盘641可以通过螺纹连接件与走行轮300的轮毂连接，制动钳642可以与齿轮减速器620的箱体相连，制动驱动单元643用于驱动制动钳642。在本公开的一些实施例中，制动驱动单元643可以为气缸。当然，制动器640也可以采用液压式的制动驱动单元643或气压转液压式的制动驱动单元643。
本公开实施例还公开了一种转向架总成1000，根据本公开实施例的转向架总成1000包括转向架构架100、走行轮300和上述任一实施例描述的电动总成600。根据本公开实施例的转向架总成1000，整体结构简单，占用空间少，重量轻，能量利用率高，有利于节能环保。
本公开实施例还公开了一种跨坐式单轨车辆，根据本公开实施例的跨坐式单轨车辆包括上述任一实施例描述的转向架总成1000。根据本公开实施例的跨坐式单轨车辆，结构简单，重量轻，能效高，有利于节能环保。
下面参考图1和图10-图12描述根据本公开实施例的悬挂系统700。
悬挂系统700支撑在转向架构架100与车体之间。如图10所示，悬挂系统700包括弹性件740和减振器组件，减振器组件包括悬挂安装座710、横向减振器720、竖向减振器730。悬挂安装座710适于与车体相连，横向减振器720连接在悬挂安装座710与转向架构架100之间，竖向减振器730连接在悬挂安装座710与转向架构架100之间，弹性件740连接在悬挂安装座710与转向架构架100之间。在本公开的一些实施例中，弹性件740为沙漏弹簧，如图1和11所示。
由此，弹性件740、横向减振器720和竖向减振器730可以共同保证跨坐式单轨车辆在 行驶过程中的上下方向、左右方向和前后方向的平稳性，而且悬挂系统700可以起到减振缓冲效果，从而可以降低轨道车辆在行驶过程中的振动或颠簸感，以及可以降低跨坐式单轨车辆的行驶噪音。
在本公开的一些实施例中，悬挂安装座710位于转向架构架100的悬挂支撑座120的上方，弹性件740的上端连接在悬挂安装座710上，弹性件740的下端连接在悬挂支撑座120上。横向减振器720铰接在悬挂安装座710和构架本体110之间，竖向减振器730铰接在悬挂安装座710和悬挂支撑座120之间。
其中，横向减振器720与构架本体110之间的铰接方式、横向减振器720和悬挂安装座710之间的铰接方式、竖向减振器730与悬挂安装座710之间的铰接方式以及竖向减振器730和悬挂支撑座120之间的铰接方式均为球铰，这样可以提高悬挂系统700的减振效果，而且还可以防止应力集中现象，从而可以提高悬挂系统700的可靠性。
参考图10，为了使得悬挂系统700构建合理，以及为了使得横向减振器720和竖向减振器730更好地工作，横向减振器720和竖向减振器730可以分别位于弹性件740的两侧。
在本公开的一些实施例中，悬挂系统700为偶数个，例如两个或四个，且关于转向架构架100的中心对称布置，从而可以防止车体在水平面内扭转，进而可以提高轨道车辆在行驶过程中的平稳性。
在如图1和11所示的实施例中，弹性件740为沙漏弹簧且与转向架构架100的悬挂支撑座120相连。具体地，转向架总成1000还包括：支撑板762，支撑板762安装在悬挂支撑座120上，弹性件740安装在支撑板762上。例如，弹性件740可以通过螺纹紧固件与支撑板762相连。支撑板762可以沿前后方向延伸，每个支撑板762上均安装有两个弹性件740。转向架构架100具有两个沿左右方向间隔开的悬挂支撑座120，每个悬挂支撑座120上均连接有支撑板762。也就是说，每个转向架构架100可以设有四个弹性件740，四个弹性件740分别分布在转向架构架100的构架本体110的两侧，即两个弹性件740分布在转向架构架100的构架本体110的一侧，另外两个弹性件740分布在转向架构架100的构架本体110的另一侧。换言之，设有四个悬挂系统700，四个悬挂系统700关于转向架构架100的中心对称地分布在转向架构架100的构架本体110的两侧。
需要说明的是，为了便于示出弹性件740与其他部件的连接关系和位置关系，在图1和11的实施例中并未示出悬挂安装座710。
在本公开的另一些实施例中，弹性件740为空气弹簧(即将上述沙漏弹簧替换为空气弹簧，该实施例未示出)，而悬挂系统700的其他构件均未改变，则根据本公开该些实施例的转向架总成1000包括转向架构架100、牵引机构200和具有空气弹簧的悬挂系统700。
在该些实施例中，牵引机构200为上述任一实施例描述的牵引机构200，牵引机构200包括牵引架210，牵引架210为拱形，牵引架210沿前后方向跨坐在转向架构架100上，且牵引架210适于与车体相连，悬挂系统700安装在转向架构架100上，悬挂系统700用于支 撑车体。
由于空气弹簧的支撑高度可调，因此便于调节车体与转向架构架100的相对位置，使得根据本公开该些实施例的转向架总成1000的适用范围更广。此外，将采用空气弹簧的悬挂系统700与具有上述结构的牵引机构200配合，使得转向架总成1000的工作更稳定可靠。
在本公开的又一些实施例中，如图12所示，悬挂系统700包括空气弹簧761，则根据本公开该些实施例的转向架总成1000包括转向架构架100、牵引机构200和多个空气弹簧761。
