具体而言，两组抗点头机构2可以分别设在车体的左右两侧，每个推力杆体22的上端可以与对应的扭杆摆臂23转动相连，每个推力杆体22的下端可以与对应的固定轴221转动相连。每组抗点头机构2中的两个扭杆摆臂23可以分别穿设在对应的扭杆21上并与扭杆21固定相连，扭杆21的两端可以分别与车体固定相连。如图5所示，在本申请的一个具体示例中，转向架200还包括两个固定架202，两个固定架202位于构架201的左右两侧，两组抗点头机构2分别与对应的固定架202相连。其中，每个固定轴221上均设有两个间隔设置的装配孔221a，固定架202上设有对应的螺钉孔202b。当抗点头机构2与固定架202装配时，固定轴221上的装配孔221a与固定架202上的螺钉孔202b一一对应，然后采用螺钉分别穿过对应的装配孔221a和螺钉孔202b以将抗点头机构2与固定架202连接在一起。
当跨坐式单轨列车运行和制动时，车体产生的俯仰力通过转向架200上的固定架202传递至两组抗点头机构2的推力杆体22上，同组的两个推力杆体22可以相对与其对应的固定架202左右摆动，也可以相对与其转动连接的扭杆摆臂23上下和左右摆动，同组推力杆体22上的推力杆体22和扭杆摆臂23可以将车体的俯仰力转化成扭转力矩传递 至与其相连的扭杆21上，扭杆21可以发生扭曲变形以平衡部分的扭转力矩，另一部分的扭转力矩可以通过扭杆21传递至车体上，车体的制动系统可以将该部分扭转力矩平衡掉，从而可以减轻车体在制动时的俯仰程度，实现抗车体点头的效果，使跨坐式单轨列车的运行更加平稳。
由此，通过上述设置，两组抗点头机构2设置在转向架200的左右两侧可以有效的减小跨坐式单轨列车制动时的俯仰程度，而且抗点头机构2可以适用于高地板和低地板的轨道列车，同时又可以使抗点头机构2适用于单轴转向架、双轴转向架及多轴转向架，从而可以大大提升抗点头机构2的适用性。牵引机构1和车体左右两侧的两组抗点头机构2可以使牵引系统100对转向架200组成半包围结构，从而可以使牵引系统100的结构更加简单、紧凑，实现跨坐式单轨列车的牵引功能与抗点头功能的相互独立，还可以方便牵引系统100的拆卸和维护，进而可以提升牵引系统100的实用性能。

如图7所示，根据本申请的一些实施例，每个扭杆摆臂23可以通过铰接头231与推力杆体22转动配合，由此可以提升扭杆摆臂23的力传动效果。可以理解的是，铰接头231的安装比较方便，结构灵活度比较高，可以承受较大的扭转力矩，从而可以减轻车体的俯仰程度。
如图3-图5、图7所示，根据本申请的一些实施例，每个推力杆体22的下端可以固定有连接部222，连接部222的下表面可以形成为弧形，固定轴221可以穿设在连接部222上，连接部222相对于固定轴221可转动，由此可以提升推力杆体22的力传动效果。例如，如图3和图5所示，每个推力杆体22的连接部222均形成为圆盘形，每个固定架202上均设有两个在其长度方向上间隔设置的装配槽202a，每个连接部222下端可以伸入到装配槽202a内。由此，可以使推力杆体22与固定架202的配合结构更加紧凑。连接部222可以与装配槽202a之间形成球面接触，当推力杆体22相对固定轴221进行转动时，可以使连接部222与装配槽202a之间的相对转动更加平顺，从而可以提升抗点头机构2的运行平稳性。可选地，可以将连接部222与推力杆体22设置成一体成型件，可以采用铸造的方法加工而成。也可以将连接部222和推力杆体22设置成分体件，可以采用螺栓连接或焊接的方式将连接部222和推力杆体22连接在一起。
如图4-图5所示，根据本申请的一些实施例，扭杆摆臂23可以外套固定在扭杆21上，由此可以使扭杆摆臂23与扭杆21之间的配合更加简单、方便装配。可选地，扭杆摆臂23和扭杆21之间可以采用花键25配合，由此可以提升抗点头机构2的结构稳定性。可以理解的是，花键25与扭杆21的对中性比较好，而且还具有良好的导向性，由此可以使抗点头机构2顺利抵消掉车体在高速运行时产生的制动力，从而可以提升抗点头机构2的抗点头效果。
如图4-图5、图7所示，根据本申请的一些实施例，每个扭杆21的两端可以设有固定座24，固定座24外套固定在扭杆21上，固定座24上可以设有固定孔241a，固定座24可以通过穿过固定孔241a的连接固定件(图中未示出)固定在车体上，由此可以使抗点头机构2与车体的固定方式更加简单。可选地，连接固定件可以为螺钉。
例如，如图8所示，固定座24可以包括第一连接部241和第二连接部242，其中第一连接部241形成为平板状，第一连接部241上设有四个均匀间隔设置的固定孔241a。第二连接部242与第一连接部241为一体铸造件，第二连接部242形成为圆柱筒结构并设在第一连接部241的下端，第二连接部242上的一端设有插入孔(图中未示出)，第二连接部242的另一端(远离扭杆21的一侧)设有四个均匀间隔设置的连接通孔242a。当固定座24与扭杆21配合时，首先将扭杆21的一端插入到插入孔内，然后采用螺钉穿过对应的连接通孔242a将固定座24与扭杆21连接在一起，最后采用连接固定件穿过固定孔241a将固定座24与车体连接在一起。
如图2、图9-图10所示，根据本申请的一些实施例，每个牵引杆13上可以设有配合部131和连接轴132，配合部131上穿设有连接轴132，配合部131相对连接轴132可转动，每个连接轴132的伸出配合部131的两个端部上分别设有螺杆133，构架201上可以设有连接座201a，连接座201a上设有伸入空间201b，连接座201a上可以设有位于伸入空间201b上下两侧的连接孔201c，螺杆133可以穿过相应的连接孔201c后与螺母配合，由此可以使牵引杆13与转向架200之间的装配方式更加简单、方便安装和拆卸。
具体而言，可以在构架201的左右两端分别设置连接座201a，连接座201a的一端与构架201连接在一起，连接座201a的另一端形成敞开的伸入空间201b。当牵引杆13与连接座201a配合时，配合部131可以伸入到伸入空间201b内，螺杆133伸入到对应的连接孔201c内并通过旋合连接与对应的螺母配合。当牵引机构1工作时，配合部131可以相对连接轴132进行转动，由此可以带动牵引杆13相对构架201左右摆动，可以使牵引系统100的运行更加平稳。
如图9-图10所示，在本申请的一些可选的实施例中，每个牵引杆13的两端可以分别设有配合部131和连接轴132，每个牵引摆臂12上可以设有与相应的连接轴132上的两个螺杆133配合的配合孔，螺杆133穿出相应的配合孔后与螺母配合，由此可以使牵引机构1的结构更加简单、还可以提升牵引机构1运行的平稳性。可以理解的是，牵引杆13两端的配合部131可以分别相对与其对应的连接轴132进行转动，当牵引机构1工作时，牵引机构1可以根据轨道的延伸方向灵活调整牵引杆13的旋转方向和旋转角度，由此可以提升牵引系统100的控制精度和运行平稳性。可选地，每个牵引杆13两端的配合部131均可以设置成圆柱形，由此可以使配合部131的运行更加平顺。
如图9-图10所示，在本申请的一些实施例中，牵引杆13内可以设有插入空间，牵引杆13的外周壁可以设有与插入空间连通的缺口134，缺口134延伸至牵引杆13的端面上，配合部131的一部分可以伸入到插入空间内，牵引机构1还可以包括卡箍14和固定连接轴15，卡箍14形成为开环形且外套在牵引杆13上，固定连接轴15可以穿过卡箍14的两个开口端141，固定连接轴15的穿出每个开口端141的端部固定有螺母以将牵引杆13紧固在配合部131上，由此可以使得配合部131与牵引杆13的配合方式更加简单、方便安装和拆卸。
具体而言，可以在牵引杆13的外周壁上设有至少一个缺口134，当配合部131与牵引杆13配合时，缺口134可以使牵引杆13发生弹性变形以增大插入空间的配合面积，从而可以方便配合部131插入到插入空间内。当配合部131插入到牵引杆13内时，可以将卡箍14外套在牵引杆13与配合部131的连接处，固定连接轴15可以通过与螺母旋合配合以减小卡箍14的开口端141的开口面积，同时产生紧固力。插入空间的端部在紧固力的作用下进行收缩，从而可以使配合部131与牵引杆13牢固的连接在一起。当需要更换或维修配合部131时，可以将固定连接轴15上的螺母拧开，紧固力消失，插入空间的端部张开，由此可以将配合部131从插入空间内抽出，操作比较方便。
根据本申请实施例的跨坐式单轨列车，包括根据本申请上述实施例的牵引系统100。具体而言，单轨列车跨坐式的设在轨道梁上。“跨坐”是对轨道车辆进行限定，即轨道车辆的车体骑跨在轨道梁上运行，而对于转向架200中的水平轮与轨道梁的相对位置则没有特殊限定。例如，水平轮可自由配合于轨道梁的外侧壁或内侧壁以适应不同尺寸的轨道梁结构。换言之，在本申请提供的轨道交通系统中，轨道车辆跨坐在轨道梁上，即为车体包裹轨道梁结构，车身宽度尺寸大于轨道梁宽度尺寸。
如图1所示，在本申请的一个具体示例中，跨坐式单轨列车的转向架200包括构架201、固定架202、制动装置203、行走轮总成204、轮边驱动总成205、二系悬挂总成 206、稳定轮总成207和导向轮总成208。构架201可以通过连接座201a与牵引机构1相连，构架201可以通过固定架202分别与两组抗点头机构2相连。制动装置203可以给车体提供制动力，从而可以实现车体的刹车和制动。二系悬挂总成206可以使车体的高度保持平衡，从而可以提升抗点头机构2的运行平稳性。行走轮总成204、轮边驱动总成205、稳定轮总成207和导向轮总成208可以共同配合以保证跨坐式单轨列车的正常运行。
根据本申请实施例的跨坐式单轨列车，通过设置上述牵引系统100，在牵引机构1两侧分别设置抗点头机构2，可以减轻车体在制动时的俯仰程度，使跨坐式单轨列车的运行更加平稳。通过将牵引系统100和转向架200组成半包围结构，可以使牵引系统100的结构更加简单、紧凑，实现跨坐式单轨列车的牵引功能与抗点头功能的相互独立，还可以方便牵引系统100的拆卸和维护，大大提升了跨坐式单轨列车的实用性能。
如图4-图5、图7所示，本申请实施例的用于牵引系统100的抗点头机构2，包括：扭杆21、两个在扭杆21的轴线方向上间隔分布的扭杆摆臂23和两个推力杆体22。扭杆21适于固定在车体上，两个扭杆摆臂23的第一端均可以与扭杆21相连，每个推力杆体22可以竖直延伸，每个推力杆体22的上端可以与其中一个扭杆摆臂23的第二端转动配合，每个推力杆体22的下端可以设有固定轴221，固定轴221的长度方向可以与扭杆21的长度方向平行，推力杆体22相对固定轴221可转动，固定轴221适于与牵引系统100中的牵引机构1相连。
例如，两组抗点头机构2可以分别设在车体的左右两侧，每个推力杆体22的上端可以与对应的扭杆摆臂23转动相连，每个推力杆体22的下端可以与对应的固定轴221转动相连。每组抗点头机构2中的两个扭杆摆臂23可以分别穿设在对应的扭杆21上并与扭杆21固定相连，扭杆21的两端可以分别与车体固定相连。
下面参考一个具体实施例详细描述本申请实施例的抗点头机构2的工作过程。
跨坐式单轨列车的转向架200可以包括构架201、固定架202、制动装置203、行走轮总成204、轮边驱动总成205、二系悬挂总成206、稳定轮总成207和导向轮总成208。转向架200为单轴转向架，即构架201可以围绕行走轮总成204的中心轴旋转。每个推力杆体22的下端通过对应的固定轴221与固定架202转动相连，每个推力杆体22的上端可以与对应的扭杆摆臂23转动相连，每组抗点头机构2中的两个扭杆摆臂23分别与扭杆21采用花键205配合，扭杆21的前后两端分别通过固定座24与车体相连。
当跨坐式单轨列车在进行正常运行时，轮边驱动总成205可以驱动行走轮总成204运行，导向轮总成208可以紧密贴合在轨道的侧壁上以对跨坐式单轨列车起到导向的作 用。其中，可以在轨道的一侧侧壁上设置导向轮总成208，也可以在轨道的两侧侧壁上同时设置导向轮总成208。导向轮总成208可以与轨道的内侧壁贴合，导向轮总成208也可以与轨道的外侧壁贴合。
当跨坐式单轨列车进行转弯时，位于车体两侧的稳定轮总成207可以对车体起到支撑的作用，可以防止车体发生倾覆。例如，当车体向左转弯时，在离心力的作用下，车体会向左倾斜，左侧的稳定轮总成207可以对车体进行支撑，由此可以使车体保持平衡。当车体向右转弯时，在离心力的作用下，车体会向右倾斜，右侧的稳定轮总成207也可以对车体进行支撑，由此也可以使车体保持平衡。
当跨坐式单轨列车在运行状态，当遇到较差路况时，车体会受到颠簸而出现点头的现象，在起步运行、变速运行或者制动过程中，车体也会因为制动力矩或者惯性作用而出现点头的现象。点头即车体的前端向下倾斜，通过设置抗点头机构2，车体点头产生的摆动力可以传递至每组抗点头机构2中的两个扭杆摆臂23，每个扭杆摆臂23与对应的推力杆体22之间形成扭转力矩。在扭转力矩的作用下，扭杆21可以发生扭曲变形。扭杆21可以为弹性件，扭杆21可以通过弹性变形以抵消扭转力矩，由此可以减小车体的摆动量，可以减轻车体的俯仰程度。此外，当跨坐式单轨列车在进行制动和发生颠簸时，二系悬挂总成206均可以对车体进行起到缓冲减震的效果，从而可以提升跨坐式单轨列车的运行平稳性。
对于单轴转向架，在起步运行、变速运行或者制动过程中，构架201会因为制动力矩或者惯性的作用围绕行走轮总成204的中心轴转动而出现点头现象。在这里以制动过程中的点头现象为例进行说明，当跨坐式单轨列车进行制动时，制动装置203会对行走轮总成204进行制动以使跨坐式单轨列车进行减速。在惯性力的作用下，构架201可以围绕行走轮总成204的中心轴转动而出现点头的现象，即转向架200的前端向下倾斜、转向架200后端翘起。转向架200产生的摆动力会通过固定架202传递至每组抗点头机构2中的两个推力杆体22上。每个推力杆体22与对应的扭杆摆臂23之间形成扭转力矩，在扭转力矩的作用下，扭杆21可以发生扭曲变形。扭杆21可以为弹性件，扭杆21可以通过弹性变形以抵消扭转力矩，由此可以减小转向架200的摆动量，从而可以减轻转向架200在制动时的俯仰程度，实现抗转向架点头的效果，使跨坐式单轨列车的运行更加平稳。
由此，通过上述设置，抗点头机构2不但可以降低车体在运行过程中的俯仰程度，可以对车体起到抗点头的作用。而且，抗点头机构2还可以减小转向架200围绕行走轮总成204的中心轴的摆动量，从而还可以对转向架200起到抗点头的作用，可以使跨坐 式单轨列车的运行更加平稳。
根据本申请实施例的用于牵引系统的抗点头机构2，结构简单，而且具有很好的抗点头效果，大大提升了牵引系统100的实用性能。

如图1、图4-图5所示，两组抗点头机构2分别设在转向架200的左右两侧。每个抗点 头机构2包括扭杆21、两个推力杆体22和两个扭杆摆臂23。扭杆21的长度方向与牵引横杆11的长度方向垂直，每个扭杆21的两端均设有固定座24。如图8所示，固定座24包括第一连接部241和第二连接部242，其中第一连接部241形成为平板状，第一连接部241上设有四个间隔设置的固定孔241a。第二连接部242与第一连接部241为一体铸造件，第二连接部242形成为圆柱筒结构并设在第一连接部241的下端，第二连接部242上的一端设有插入孔，第二连接部242的另一端(远离扭杆21的一侧)设有四个均匀间隔设置的连接通孔242a。当固定座24与扭杆21配合时，首先将扭杆21的一端插入到插入孔内，然后采用螺钉穿过对应的连接通孔242a将固定座24与扭杆21连接在一起。最后采用连接固定件穿过固定孔241a将固定座24与车体连接在一起。

当跨坐式单轨列车运行和制动时，车体产生的俯仰力通过转向架200上的固定架202传递至两组抗点头机构2的推力杆体22上，同组的两个推力杆体22可以相对与其对应的固定架202左右摆动，也可以相对与其转动连接的扭杆摆臂23上下和左右摆动，同组推力杆体22上的推力杆体22和扭杆摆臂23可以将车体的俯仰力转化成扭转力矩传递至与其相连的扭杆21上，扭杆21可以发生扭曲变形以平衡部分的扭转力矩，另一部分的扭转力矩可以通过扭杆21传递至车体上，车体的制动系统可以将该部分扭转力矩平衡掉，从而可以减轻车体在制动时的俯仰程度，实现抗车体点头的效果，使跨坐式单轨列车的运行更加平稳。
需要进行说明的是，上述描述中的“同组的两个推力杆体22”可以理解为每个抗点头机构2上的两个间隔设置的推力杆体22，同组的两个推力杆体22通过对应的扭杆摆臂23与同一个扭杆21相连。
