可见，牵引电机30的输出轴与齿轮箱20相连接的一端实现驱动，与制动装置相连接的另一端实现制动。
本实施例利用齿轮箱20的从动齿轮轴直接安装车轮，齿轮箱20上设置安装架230、一系弹簧座、安全座，采用橡胶节点与构架安装，电机与齿轮箱之间设置联轴器40，电机弹性安装在构架上；制动盘安装在电机的输出轴上，液压制动单元直接安装在电机机体上；制度盘与输出轴、联轴器40、电机输出轴以及液压制度单元与电机机体均采用锥度配合。
如图2所示，齿轮箱20包括从动齿轮和与所述从动齿轮传动连接的传动轴，走行轮10安装在传动轴上。为了实现传动轴与走行轮10之间的连接，传动轴的两端均具有端面齿32，传动轴通过各个端面齿32与相应的走行轮10连接。
优选地，转向架还包括构架，齿轮箱20上设置有用于与构架连接的第一弹性连接件50，且驱动装置上设置有安装件60和设置在安装件60上的弹性垫片70，驱动装置通过安装件60和弹性垫片70与构架连接。优选地，该安装件60为安装螺栓。优选地，第一弹性连接件50为叠成橡胶弹簧。
齿轮箱20上设置有润滑油油泵80。由于该齿轮箱20与一般结构齿轮箱20不同，内部两级减速，且齿轮箱20上、下高度差较大，为保证齿面与轴承的充分润滑。在齿轮箱20一端设计润滑油油泵80，且由电控制，可以在车辆运行时实现充分润滑。
优选地，齿轮箱20上还设置有注油孔，注油孔上设置有注油螺堵81。齿轮箱20上设置有锁紧螺栓90，传动轴的端面齿32通过该锁紧螺栓90与齿轮箱20的从动齿轮连接。齿轮箱20上设置有用于与构架连接的组装件100。齿轮箱20上设置有安全吊挂130。齿轮箱20上设置有温度传感器120。
本申请还提供了一种车辆，车辆包括上述涉及的转向架。
牵引电机30通过联轴器40输出扭矩，通过齿轮箱20内部设计成伞齿轮与平行齿轮结合的方式实现扭矩垂直传递。
齿轮箱20的从动齿轮与传动轴过盈配合，在传动轴的两侧加工端面齿，端面齿与车轮进行配合并轴向锁紧，从而实现动力传送。
导向轮220与齿轮箱20直接装配，在转向架走行过程中，不仅需要走行轮10转动，还需要导向轮220辅助，当过弯道时，走行轮10需要与竖轨接触，在齿轮箱20下部铸造走行轮安装支架。
齿轮箱20弹性悬挂，齿轮箱20两个部分与构架弹性链接，一端是弹性节点，一端是叠层橡胶弹簧结构，可靠性高，减震性能好。
牵引电机与构架弹性链接，通过安装件60和橡胶饼与构架软连接，大大提高了牵引电机与构架链接的减震效果。
制动盘、联轴器40与牵引电机30链接，牵引电机30转子一端伸出与联轴节锥轴过盈配合，另一侧同样伸出长锥轴，与制动盘链接。该种方式同样减小了驱动与制动的结构空间。
类似结构走形轮通过花键链接分布在齿轮箱20的一侧，前后车辆集中在一根轨道上，目前此种结构为两侧分布车轮，有效的将悬挂系统从两轮对中间穿入，实现车辆的自由钟摆式减震。结构实现多功能集成，似的整个转向架系统机构紧凑。
本申请中的转向架，走行轮10安装在齿轮箱20上，驱动装置与齿轮箱20驱动连接，通过驱动装置驱动齿轮箱20，以实现走行轮10转动运动，制动装置与驱动装置连接，以对驱动装置进行制动，实现走行轮10的制动。
本申请中的转向架包括走行轮10；请参考图3至图6，转向架还包括导向轮220，导向轮220设置在走行轮10的周向外侧，导向轮220的轮体轴线与走行轮10的轮体轴线垂直。
本申请通过使转向架包括导向轮220，并使导向轮220的轮体轴线与走行轮10的轮体轴线垂直，可以使导向轮220承担过弯道的转向架的导向作用和转向架运行过程中的蛇形运动，使转向架稳定地设置悬挂车的轨道上，进而使悬挂车在轨道上稳定地运行，从而解决了现有技术中的悬挂车无法稳定地在轨道上运行的问题。
为了实现导向轮220的安装，如图3至图6所示，转向架还包括安装架230，导向轮220可转动地设置在安装架230上。此时，导向轮220设置在安装架230上，导向轮220在安装架230上可转动地设置。

为了实现安装架230与导向轮220之间的连接，如图3所示，安装架230包括：支撑部231，导向轮220可转动地安装在支撑部231上。具体地，支撑部231为条形板，安装架230具有两个相交设置的支撑部231。
为了实现支撑部231与导向轮220之间的连接，安装架230还包括销轴232，销轴232穿设在支撑部231上，导向轮220可转动地与销轴232连接以安装在支撑部231上。通过将销轴232穿设在支撑部231上，导向轮220实现了在支撑部231上的可转动设置。
如图5所示，销轴232上套设有轴承233，导向轮220通过轴承233与所述销轴232连接。通过设置轴承233，可以比较方便地将导向轮220可转动地安装在销轴232上。
为了实现对轴承233的支撑，轴承233的外侧套设有轴承套234，导向轮220和轴承套234上穿设有第一紧固件251。优选地，第一紧固件251为紧固螺栓。
在本实施例中，安装架230还包括压板235，压板235设置在轴承233的端部以将轴承233固定在销轴232上。通过设置压板235，可以比较方便地实现对轴承233的限位。
为了实现压板235与销轴232之间的连接，压板235和销轴232上穿设有第二紧固件252，压板235通过第二紧固件252固定在销轴232的端部。优选地，第二紧固件252为紧固螺栓。
在本实施例中，销轴232的两端均安装有导向轮220。即一个销轴232上设置有两个导向轮220。此时，支撑部231为两个，各个支撑部231上均设置有两个相对设置的导向轮220，这样，可以提高导向效果。
为了实现安装架230与齿轮箱20之间的连接，如图4所示，安装架230和齿轮箱20的箱体上穿设有第三紧固件253，安装架230通过第三紧固件253与齿轮箱20固定连接。优选地，第三紧固件253为紧固螺栓。

本实施例通过设置锁紧螺母254，并将锁紧螺母254设置在轴承233的外侧，可以调整并保证旋转系统的轴向游隙，导向轮220成对安装，提高了系统的稳定性。这种结构安装简单，便于维修，有效的提高系统可靠性。
