具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
图1是本发明实施例提供的内侧悬挂直驱径向转向架的结构示意图，图2是图1中A-A的剖视示意图，图3是本发明实施例提供的轮对轴箱装置的结构示意图，图4是本发明实施例提供的轮对轴箱装置的局部结构剖视示意图，图5是本发明实施例提供的轴箱的结构示意图，图6是本发明实施例提供的构架主体的结构示意图，图7是本发明实施例提供的构架侧梁端部的结构示意图，图8是本发明实施例提供的悬挂减振系统和底层监控系统的结构示意图，图9是本发明实施例提供的悬挂减振系统的纵向中心剖视图，图10是本发明实施例提供的弹性节点的结构示意图。
目前，部分欧洲铁路客车采用内侧悬挂结构的转向架，但其在结构上采用空气弹簧、牵引拉杆、转臂定位和整体驱动电机等客车专用结构，构造复杂、重量大，无法在铁路货车上使用；另外，部分货车企业提出一些货车采用内侧悬挂结构的转向架，但其一系定位结构主要采用弹性导柱定位，采用平板橡胶或V型橡胶主悬挂，这样在空车情况下悬挂系统无法提供大挠度，不能有效提升动力学性能，并且弹性导柱定位无法提供足够的轮对纵向和横向位移，同时缺少驱动系统，无法适应车辆自驱动的需求。
因此，本实施例提供一种内侧悬挂直驱径向转向架，用来支撑车体，承受并且传递从车体至轮对之间或从轮轨至车体之间的各种载荷的作用，以提高列车运行的稳定性，本实施例中，通过将构架主体与悬挂减振装置固定在轮对轴箱装置内侧，这样可以减小构架的宽度和车轴的长度，以及减少 车轴、构架的体积和材料使用量，进而降低车体的自重，从而避免了因构架过宽会导致车体自重大的问题。
参见图1和图2所示，本实施例中，内侧悬挂直驱径向转向架可以包括轮对轴箱装置10、构架主体20和至少一个悬挂减振装置30，本实施例中，悬挂减振装置30具体以设置4套为例进行说明，其中，悬挂减振装置30一端与轮对轴箱装置10相连，悬挂减振装置30另一端与构架主体20底端相连，构架主体20顶端与车体相连。
本实施例中，参见图1所示，构架主体20与悬挂减振装置30固定在轮对轴箱装置10内侧，这样可以减小构架主体20的宽度，以及减少构架主体20的体积和材料使用量，进而降低车体自重，解决了采用现有外侧悬挂转向架会导致车体自重大，增加能源消耗以及影响车体有效运载能力的问题。
本实施例中，轮对轴箱装置10具体设置在转向架最外侧，分别连接转向架与轨道，本实施例中，具体以设置两个轮对轴箱装置10为例进行说明。
本实施例中，构架主体20包括横梁21和两个侧梁22(具体参见图6所示)，横梁21焊接在两个侧梁22之间，侧梁22包括上盖板224和下盖板225，其中，上盖板224朝向下盖板225一侧设有导柱226(具体参见图7所示)，导柱226用于连接弹性节点32，下盖板225表面开设限位孔2251，这样通过设置限位孔2251，导柱226穿过限位孔2251，导柱226对轮对轴箱装置10进行弹性定位，限位孔2251可用于限制轮对轴箱装置10的水平位移，且限位孔2251靠近上盖板224两端开设。
本实施例提供的内侧悬挂直驱径向转向架，通过包括轮对轴箱装置10、构架主体20和至少一个悬挂减振装置30，悬挂减振装置30一端与轮对轴箱装置10相连，悬挂减振装置30另一端与构架主体20底端相连，构架主体20与悬挂减振装置30固定在轮对轴箱装置10内侧，构架主体20顶端与车体相连，构架主体20包括横梁21和两个侧梁22，横梁21焊接在两个侧梁22之间，侧梁22包括上盖板224和下盖板225；上盖板224朝向下盖板225一侧设有导柱226，下盖板225表面开设限位孔2251，导柱226对轮对轴箱装置10进行弹性定位，限位孔2251对轮对轴箱装置10进行限位，限位孔2251靠近上盖板224两端开设。
这样通过将构架主体20与悬挂减振装置30设置在轮对轴箱装置10内侧，可以减小构架的宽度和车轴的长度，以及减少车轴11、构架的体积和材料使用量，进而降低车体的自重，从而避免了因构架过宽导致车体自重大的问题，同时在下盖板225表面开设限位孔2251，导柱226穿过限位孔2251，导柱226对轮对轴箱装置10进行弹性定位，限位孔2251可用于限制轮对轴箱装置10的水平位移，因此，本发明提供的内侧悬挂直驱径向转向架，解决了采用现有外侧悬挂转向架会导致车体自重大，增加能源消耗，影响车体有效运载能力，以及采用现有内侧悬挂转向架结构、参数和驱动能力不适应货车性能和驱动要求的问题。

本实施例中，通过将车轮12设置在车轴11的最外端，这样不仅可以减小构架的宽度和车轴的长度，还可以使车轮12成为噪声屏障，进而实现转向架低噪声的效果。
本实施例中，参见图4所示，车轮12与轴承13之间还可以设置有定位环15，其中，通过在车轮12与轴承13之间设置定位环15，可以调整车轮12内侧之间的间距。
本实施例中，参见图4所示，车轴11还可以采用空心轴，其中，空心轴中心孔111的直径可以大于等于65mm，具体的，空心轴中心孔111的直径 可以为65mm，也可以为70mm，本实施例中，通过将车轴11设置为空心轴，这样车体在运行时可以降低整个装置的重量。
本实施例中，参见图4所示，车轴11的两侧还可以设置电机挡边112，通过设置电机挡边112可以对电机17起到位置固定的作用，另外，在车轮12上还可以安装降噪环121，以使车轮12成为降噪车轮12，进而降低车体运行时的噪声，并减少对铁路沿线居民造成困扰的问题。
在上述实施例的基础上，参见图5所示，轴箱14上开设安装孔141，其中，安装孔141具体呈长圆形、且安装孔141顶部两侧带固定挡边，轴箱14可以通过安装孔141的顶部坐落在轴承13的外圈上。

在上述实施例的基础上，参见图6所示，构架主体20包括横梁21和两个侧梁22，横梁21焊接在两个侧梁22之间，形成H型结构，这样通过将横梁21与侧梁22进行整体焊接，能够增强转向架的刚度，并提高列车的运行稳定性，其中，侧梁22采用中间下凹结构，这样在运行的过程中可以降低车体重心。
本实施例中，横梁21中心一侧设有电机座211，另一侧设有制动吊座212，侧梁22中部外侧设有旁承座221，侧梁22端部内侧设有减振器座223，旁承座221上安装弹性旁承222，横梁21中部设有球面心盘213，弹性旁承222与球面心盘213一同构成车辆接口，这样可以满足对既有车辆的通用性。

本实施例中，底座321上设内腔，具体的，内腔可以为长圆形截面形状，两个内圈323位于弹性节点32中心处，且两个内圈323构成分体圆管结构，弹性体322具体可以为两个，位于两个内圈323与内腔之间，分别与底座321的一端内腔和一个内圈323固定，这样可以形成两个相互分离的弹性结构，当内圈323受到纵向力时，压力可传递到一侧弹性体322上，这样可以避免另一侧的弹性体322受到拉力而导致整体结构寿命降低的问题。
本实施例中，参见图9所示，弹性节点32内还可以设有低摩衬套324，通过设置低摩衬套324，可以减少导柱226和弹性节点32在垂向位置相对变化引起的磨耗。
