下面结合附图1至图3具体描述根据本发明实施例的跨座式单轨道岔梁行走支撑台车100。
根据本发明实施例的跨座式单轨道岔梁行走支撑台车100，包括台车主体10和车轮组，车轮组包括两组车轮20，每组车轮20分别设在台车主体10的两侧，两组车轮20的轴线存在夹角，车轮20与台车主体10配焊或者螺栓连接。
换言之，该跨座式单轨道岔梁行走支撑台车100主要由台车主体10和车轮组组成，台车主体10的上端设有能够支撑道岔梁200的支撑部，道岔梁200与台车主体10固定相连，从而随台车主体10行走以实现与不同的轨道梁(未示出)的接合，以保证轨道梁的顺利转撤，进而实现轨道梁上的轨道车辆通过的稳定顺畅。
进一步地，车轮组主要包括两组车轮20，两组车轮20沿纵向方向(如图2所示前后方向)间隔开设在台车主体10的两侧(如图2所示的前侧和后侧)，并且装配时两组车轮20在调整好与台车主体10之间的相对位置后，与台车主体10固定相连，例如，两组车轮20可以与台车主体10之间通过配焊连接或者螺栓连接或其他连接方式，即台车主体10、两组车轮20可以形成分体式结构，便于实现部件的模块化，然后通过不同的连接方式实现组装，提高生产效率。
同时，两组车轮20可以分别支撑于轨道300上，且两组车轮20的车轮20轴线之间形成夹角，从而避免跨座式单轨道岔梁行走支撑台车100沿轨道300行走时、与轨道300发生干涉，保证跨座式单轨道岔梁行走支撑台车100的正常运行平稳，且有利于减小摩擦、延长使用寿命。
由此，根据本发明实施例的跨座式单轨道岔梁行走支撑台车100，通过将车轮组和台车 主体10设置为分体式结构，并且将二者之间通过螺栓或者配焊连接，从而在保证跨座式单轨道岔梁行走支撑台车100整体的结构强度的同时，提高支撑台车100各部件的模块化程度以及互换性，降低制造难度、提高生产效率。
在本发明的一些实施例中，车轮20包括安装板21、两个轴承座、转轴23、轴套24、轴承25和车轮本体26，安装板21与台车主体10相连，两个轴承座沿轴向间隔开设在安装板21上，转轴23的两端分别插接在两个轴承座上，转轴23形成为阶梯轴，轴套24套设在转轴23上且位于两个轴承座之间，轴承25套设在轴套24上，车轮本体26可转动地设在转轴23上。
具体地，如图3所示，车轮20主要由安装板21、两个轴承座、转轴23、轴套24、轴承25和车轮本体26组成，安装板21设在车轮20的上端且与台车主体10相连，从而实现对台车主体10的支撑作用，两个轴承座(即第一轴承座22a和第二轴承座22b)沿转轴23的轴向方向(如图3所示的左右方向)间隔开设在安装板21下端，第一轴承座22a和第二轴承座22b分别外套在转轴23的左端和右端，轴套24同轴套设在转轴23上且位于第一轴承座22a和第二轴承座22b之间，轴承25外套在轴套24上，轴承25通过轴套24间接的套设在转轴23上，车轮本体26设在轴承25上，从而使得车轮本体26通过轴承25可转动地设在转轴23和轴套24上，进而保证跨座式单轨道岔梁行走支撑台车100可以通过两组车轮20上的车轮本体26实现行走，从而便于道岔梁200的转撤。
可选地，转轴23包括沿其轴向延伸的第一轴段231、第二轴段232和第三轴段233，第一轴段231、第二轴段232至第三轴段233的径向尺寸逐渐减小，第一轴段231插接在一个轴承座(例如图3中位于左侧的第一轴承座22a)内，第三轴段233插接在另一个轴承座(例如图3中位于右侧的第二轴承座22b)内，轴套24套设在第二轴段232上。
参照图3，转轴23主要由第一轴段231、第二轴段232和第三轴段233组成，第一轴段231、第二轴段232和第三轴段233均沿轴向(如图3所示的左右方向)延伸，且第一轴段231、第二轴段232和第三轴段233的径向尺寸依次递减。
其中，第一轴段231的径向尺寸与第一轴承座22a的内圈径向尺寸大致相等；第二轴段232的径向尺寸与轴套24的内圈径向尺寸大致相等；第三轴段233的径向尺寸与第二轴承座22b的内圈径向尺寸大致相等，从而便于轴承25与第一轴承座22a、第二轴承座22b以及轴套24的组合装配，降低装配难度、提高生产效率，而且各部件之间的分体式连接，也可以进一步地提高模块化程度以及部件之间的互换性。
此外，车轮20还包括平键(未示出)，平键设在第二轴段232的邻近第一轴段231的一端上。
具体地，如图3所示，第二轴段232邻近第一轴段231一端上设有平键槽，平键槽内 设有平键，从而利用平键与平键槽之间的配合作用，限制转轴23与轴套24之间的相对转动，进而使得当支撑台车100行走时，车轮本体26相对于轴套24和转轴23转动，而轴套24和转轴23之间不发生相对转动。与相关技术中轴套与转轴之间的采用间隙配合的方案相比，利用轴承25的滚动摩擦系数小于轴套24与轮轴的摩擦系数以实现车轮本体26的连接方式，能够在简化装配难度的同时，保证支撑台车100行走的稳定性和可靠性。
其中，转轴23和轴套24上设有互相连通的油路27，油路27的一端伸出转轴23与油嘴27a连通，油路27的另一端与轴套24和轴承25之间的间隙连通。
参照图3，油路27分别设在转轴23和轴套24上，且相互连通，油路27的一端伸出转轴23与油嘴27a相连，另一端伸出轴套24与轴套24和轴承25之间的间隙相连，用户可以通过油嘴27a注入润滑油，进而使得润滑油通过转轴23和轴套24的油路27进入轴套24和轴承25之间的间隙中，从而实现对轴承25的润滑，延长跨座式单轨道岔梁行走支撑台车100使用寿命。
有利地，车轮20还包括端盖28，端盖28套设在车轮本体26的两端以封闭轴承25。
具体地，如图3所示，车轮本体26的轴向两端(即如图3所示的左端和右端)分别设有端盖28，同时，端盖28套设在轴套24上，从而利用端盖28、车轮本体26以及轴套24形成周向方向密封配合，进而避免因杂物进入轴承25、而影响车轮本体26的顺畅使用，延长车轮20的使用寿命。
优选地，轴套24与端盖28之间设有密封圈29，密封圈29套设在轴套24上。
参照图3，密封圈29套设在轴套24上且设在轴套24与端盖28之间的连接处，从而利用密封圈29的密封作用，进一步地保证端盖28、车轮本体26以及轴套24形成周向方向密封配合，从而避免杂物进入轴承25、影响车轮本体26的顺畅使用以及保证润滑间隙密闭以增强润滑效果持续时间。
优选地，第一轴段231、第二轴段232和第三轴段233一体成型。一体成型的结构不仅可以保证各部件的连接可靠性，增大转轴23的结构强度，保证支撑台车100的使用可靠性，而且成型方便简化了加工工序，从而提高生产效率。
