具体实施方式
下面详细描述本申请的实施例，参考附图描述的实施例是示例性的，下面详细描述本申请的实施例。
下面参考图1-图10描述根据本申请第一方面实施例的转向架100。转向架100可以应用于轨道车辆200例如跨座式单轨车辆。在本申请下面的描述中，以转向架100应用于轨道车辆200为例进行说明。
如图1-图3和图5所示，根据本申请第一方面实施例的转向架100，包括构架1、制动器11、隔声罩3和横向止挡2。制动器11设置在构架1上。隔声罩3与构架1密封连接。
需要说明的是，“隔声罩3与构架1密封连接”在本申请中指的是，隔声罩3与构架1的连接处形成了封闭的图形。也就是说隔声罩3与构架1的连接形成了首尾相连的闭环结构。
如图3所示，隔声罩3和构架1共同限定出容纳空间33，制动器11设置在容纳空间33内。在本申请的一些示例中，结合图1-图3和图5，隔声罩3连接在构架1的侧面，且隔声罩3的面向构架1的一侧设置有开口。
由此，当转向架100应用于轨道车辆200时，由于制动器11设置在上述容纳空间33内，制动器11高速旋转产生的噪声例如空气宽频噪声可以被隔绝在容纳空间33内，从而可以很好地降低车内噪声和车外噪声，在提高车内乘客的乘车舒适性的同时，可以避免车外噪声对周边环境的影响。而且，隔声罩3的体积较小，结构紧凑，可以降低用料成本。
横向止挡2设置在隔声罩3上，且横向止挡2位于隔声罩3的外侧，横向止挡2远离构架1的中心。由此，在轨道车辆200的运行过程中，当轨道车辆200的车体与构架1之间产生较大的横向位移时，横向止挡2可以起到很好的止挡作用，从而可以保证轨道车辆200的运行安全性。
根据本申请实施例的转向架100，通过使隔声罩3与构架1密封连接，并使隔声罩3和构架1共同限定出容纳空间33且制动器11设置在容纳空间33内，当转向架100应用于轨道车辆200时，可以很好地隔绝制动器11产生的空气噪声，从而有效降低车内噪声和车外噪声，在提高车内乘客的乘车舒适性的同时，可以避免车外噪声对周边环境的影响。而且，通过设置横向止挡2，横向止挡2可以起到很好的止挡作用，避免轨道车辆200的车体与转向架100之间产生较大的横向位移，从而可以保证轨道车辆200的运行安全性。另外，隔声罩3的体积较小，结构紧凑，可以减小整个转向架100的占用空间，且可以降低用料成本。此外，通过将横向止挡2设置在隔声罩3上，使转向架100的集成度更好，从而可以进一步提高转向架100的结构紧凑性。
在本申请的一些实施例中，参照图1-图3和图5，隔声罩3包括第一罩体31、第二罩体32和止挡安装架，止挡安装架设置在第一罩体31与第二罩体32之间，横向止挡2安装在止挡安装架上。第一罩体31的开口侧与构架1无缝连接，即第一罩体31的开口侧与构架1的连接处形成了一条连续的线段。第二罩体32的开口侧与构架1无缝连接，即第二罩 体32的开口侧与构架1的连接处形成了一条连续的线段。由此，通过设置上述的第一罩体31、第二罩体32和止挡安装架，在保证有效降低车内噪声和车外噪声的同时，方便隔声罩3的安装和拆卸。而且，通过使止挡安装架设置在第一罩体31与第二罩体32之间，可以进一步提高转向架100的集成度，保证转向架100具有较高的结构紧凑性。
在本申请的一些示例中，如图1-图3和图5所示，第一罩体31和第二罩体32均连接在构架1的侧面，且第一罩体31和第二罩体32的面向构架1的一侧设置有开口。第一罩体31的下端与横向止挡2无缝连接，即第一罩体31的下端与横向止挡2的连接处形成了一条连续的线段，第一罩体31的开口侧与构架1无缝连接。第二罩体32的上端与横向止挡2无缝连接，即第二罩体32的上端与横向止挡2的连接处形成了一条连续的选段，第二罩体32的开口侧与构架1无缝连接。如此设置，结构简单紧凑，使隔声罩3的占用空间较小，方便布置。
在本申请的一些实施例中，转向架100还可以包括垂直止挡。由此，当轨道车辆200的车体与转向架100之间产生较大的纵向位移时，垂直止挡可以起到很好的止挡作用，从而可以保证轨道车辆200的运行安全性。
在本申请的一些实施例中，如图3所示，制动器11包括制动盘111和制动夹钳112，制动夹钳112用于对制动盘111进行夹紧或放松，制动夹钳112与第一罩体31相对，且第一罩体31的宽度大于第二罩体32的宽度。由此，通过使第一罩体31的宽度大于第二罩体32的宽度，制动夹钳112可以容纳在第一罩体31与构架1之间的容纳空间33内，从而使第二罩体32的宽度可以较小，模具结构简单，可以降低成本，且整个隔声罩3的结构更加紧凑，节省空间。
在本申请的一些实施例中，参照图3和图5，第一罩体31包括第一下罩体311和第一上罩体312。第一下罩体311无缝连接在横向止挡2的上方，即第一下罩体311与横向止挡2的连接处形成了一条一条连续的线段；第一上罩体312可拆卸地连接在第一下罩体311的上方，制动夹钳112与第一上罩体312相对，第一上罩体312的宽度大于第一下罩体311的宽度。由此，通过使第一上罩体312的宽度大于第一下罩体311的宽度，制动夹钳112可以容纳在第一上罩体312与构架1之间的容纳空间33内，从而使第一下罩体311的宽度可以较小，模具结构简单，可以降低成本，且第一罩体31的结构更加紧凑，节省空间。
在本申请的一些示例中，参照图3，第一下罩体311的宽度与第二罩体32的宽度可以大致相等，且第一下罩体311的宽度和第二罩体32的宽度均小于第一上罩体312的宽度，这样，可以使隔声罩3的结构更加紧凑，减小占用空间，方便布置。
在本申请的一些实施例中，结合图5和图8，第一下罩体311与横向止挡2可拆卸地相连。如此设置，在实现第一下罩体311与横向止挡2之间的可靠连接的同时，结构简单， 方便装拆。
在本申请的一些示例中，如图5和图8所示，第一下罩体311的下端可以设有水平向外延伸出的第一翻边部3111，第一翻边部3111可以通过螺纹紧固件例如螺栓与横向止挡2连接。由此，通过上述设置，可以实现第一下罩体311与横向止挡2的牢靠连接，且方便安装和拆卸，成本较低。
在本申请的一些实施例中，参照图1，转向架100还包括悬挂装置10，悬挂装置10设置在构架1上，悬挂装置10可位于隔声罩3的远离制动器11的一侧，悬挂装置10与横向止挡2相对设置，且悬挂装置10的上表面低于第二罩体24的下端面。如此设置，可以避免第二罩体24和悬挂装置10产生干涉，方便第二罩体24的安装和拆卸。
在本申请的一些实施例中，参照图10，转向架100还包括走行轮6，走行轮6与制动器11连接，走行轮6至少部分高于悬挂装置10的上表面，且走行轮6的中心轴线低于悬挂装置10的上表面。由此，使得走行轮6凸出地板的部分较小，既实现了一定的低地板，又减少了走行轮6凸出部分占据车内空间的比例，在降低地板高度和轨道车辆200重心的同时保证了载客量和车内通透性，提高了乘客的乘坐舒适性。
在本申请的一些示例中，结合图10，走行轮6设置在构架1内，制动盘111可以与走行轮6的轮轴相连。制动夹钳112可以用于夹持制动盘111，使制动盘111对走行轮6的轮轴产生摩擦力矩，从而实现轨道车辆200的制动。悬挂装置10的上表面与轨道车辆200的车体底部相连，走行轮6的中心轴线位于地板的水平面以下。走行轮6的位于地板以上的部分的尺寸小于其位于地板以下的部分的尺寸。如此设置，可以进一步减少走行轮6凸出部分占据车内空间的比例，保证乘客的乘坐舒适性。
在本申请的一些实施例中，如图1、图3和图9所示，构架1包括电动总成安装部12，电动总成安装部12的一侧与隔声罩3密封连接，电动总成安装部12的另一侧连接有电动总成7，电动总成7用于输出制动扭矩，电动总成安装部12具有贯通的安装口，电动总成7至少部分容纳在安装口内。其中，隔声罩3连接在电动总成安装部12的远离构架1中心的一侧，电动总成7连接在电动总成安装部12的邻近构架1中心的一侧。如此设置，隔声罩3和电动总成7可以密封连接在电动总成安装部12的两侧，将安装口密封，使制动器11高速旋转产生的噪声例如空气宽频噪声可以有效被隔绝在容纳空间33内，从而可以有效降低车内噪声和车外噪声，保证车内乘客的乘车舒适性。
在轨道车辆200的行驶过程中，电动总成7可以输出制动扭矩，即控制电机输出与车轮转动方向相反的力矩来实现轨道车辆200的减速或制动。制动器11的机械制动只有在紧急制动等少数情况才会起作用，从而制动器11的工作时间较短，不容易产生过热的问题。当然，电动总成7还可以用于输出驱动扭矩，以控制轨道车辆200的正常运行。
在本申请的一些示例中，参照图1，构架1还可以包括框架本体13、悬挂安装部14、导向轮安装部15、稳定轮安装部16等。其中，悬挂安装部14、导向轮安装部15、稳定轮安装部16可以均设置在框架本体13上。由此，悬挂装置10可以通过悬挂安装部14安装在车体和框架本体13之间，从而可以传递车体与框架本体13之间的垂向、横向和纵向力，为轨道车辆200提供第二级减振，提高车体稳定性；导向轮8可以水平安装于导向轮安装部15，以实现转向架100的导向作用；稳定轮9可以水平安装于稳定轮安装部16，从而保证轨道车辆200的平稳运行。
当然，也可以根据构架1的结构设计需求，只设置稳定轮安装部16或者只设置导向轮安装部15，此时单独稳定轮9或者导向轮8即可起到导向并且维持车体平衡防止车体倾斜的作用。
在本申请的一些示例中，参照图1和图9，电动总成7与电动总成安装部12密封连接。也就是电动总成7和电动总成安装部12的连接处形成了封闭的图形。如此设置，电动总成7可以将电动总成安装部12的上述另一侧封闭，避免制动器11产生的空气噪声通过安装口传播到车内或车外，保证可以将噪声隔绝在容纳空间33内。
其中，电动总成7可以包括电机和减速器等，电动总成7可以与走行轮6的轮辋61同轴设置。这样，可以提高电动总成7例如电机、减速器与走行轮6之间的传动效率，从而实现较好的制动效果和驱动效果。
在本申请的一些示例中，参照图1和图5，电动总成安装部12大致呈拱形结构，这样，在实现电动总成7的安装、保证密封安装口的同时，可以提高电动总成安装部12的结构强度，使电动总成安装部12可以对构架1的结构起到更好的加强作用。
在本申请的一些实施例中，结合图1、图2和图5，第一罩体31上形成有检修口，检修口与制动器11相对设置，且检修口处设置有可拆卸的检修盖4，检修口与检修盖4密封连接，即检修口与检修盖4的连接处形成了封闭的图形。由此，通过上述设置，在保证隔声罩3的密封性以降低车内噪声和车外噪声的同时，方便对制动器11进行检修，结构简单，操作方便，可以提高检修效率。
在本申请的一些示例中，参照图1、图2和图5，检修口可以形成在第一罩体31的远离构架1的一侧，检修口可以大致为矩形。当需要对制动器11进行检修或维护时，可以将检修盖4从检修口处拆下，由于检修口与制动器11相对，操作人员可以通过检修口对制动器11进行检修，提高了检修维护的便捷性。检修完成后，可以将检修盖4密封在检修口处，以保证隔声罩3的密封性。
在本申请的一些实施例中，如图5所示，检修口处设有凸出于隔声罩3的外表面的检修盖安装座5，检修盖安装座5上形成有与检修口连通的开口。检修盖4覆盖开口。由此， 通过设置上述的检修盖安装座5并使检修盖4的上端设有朝向容纳空间33中心延伸的翻边41，可以在上下方向上安装螺纹紧固件，在实现检修盖4与检修盖安装座5之间的牢靠连接的同时，使检修盖4的安装和拆卸非常方便，可以提高装卸效率。
在本申请的一些示例中，结合图5，检修盖4的上端设有朝向容纳空间33中心延伸的翻边41，翻边41与检修盖安装座5的顶部通过多个螺纹紧固件可拆卸地相连。翻边41上可以形成有沿翻边41的厚度方向贯穿翻边41的两个安装孔，检修盖安装座5的顶部形成有两个安装孔。安装时，可以使翻边41搭接在检修盖安装座5的顶部，使翻边41上的安装孔与检修盖安装座5上的安装孔一一对应，然后使两个螺纹紧固件例如螺栓自上而下穿过翻边41上的安装孔与检修盖安装座5上的安装孔螺纹连接。当需要检修制动器11时，使螺纹紧固件与安装孔脱离配合以拆下检修盖4，操作人员可以从检修盖安装座5上的开口处对制动器11进行检修。如此设置，极大地提高了操作的便捷性，可以进一步提高装拆效率。
在本申请的一些实施例中，如图3和图5所示，第一罩体31上设有水平向远离容纳空间33延伸的延伸部313，检修盖安装座5设置在延伸部313上，延伸部313的远离容纳空间33的一侧设有向上延伸的限位部3131，检修盖4的下端止抵在限位部3131与检修盖安装座5之间。由此，通过设置上述的限位部3131，可以起到很好的限位作用，从而可以保证检修盖4与检修盖安装座5之间的密封性，防止制动器11产生的空气噪声从检修盖4与检修盖安装座5之间传出，且可以提高整个转向架100的结构稳定性。
在本申请的一些示例中，如图3和图5所示，限位部3131可以包括彼此相连的第一子部和第二子部，第一子部与第二子部可以相互垂直，第一子部连接在延伸部313上，第二子部向上延伸，以将检修盖4限定在第二子部与检修盖安装座5之间。如此，限位部3131在起到限位作用的同时，结构简单，加工方便。
在本申请的一些实施例中，结合图6，第一下罩体311的上端可以设有水平向远离容纳空间33延伸出的第二翻边部3112，3112和延伸部313也可以通过螺纹紧固件例如螺栓实现密封连接。如此，可以实现第一下罩体311和第一上罩体312之间的牢靠连接，且方便装拆。
在本申请的一些实施例中，如图4所示，隔声罩3包括沿朝向远离容纳空间33中心的方向依次设置的支撑层34、阻尼层35、吸音层36和隔音层37。由此，通过设置上述的支撑层34、阻尼层35、吸音层36和隔音层37，支撑层34具有较大的刚度，能够起到很好的支撑作用；阻尼层35能够有效避免支撑层34产生振动，从而可以有效避免轨道车辆200在运行过程中由于隔声罩3自身振动而产生噪声；吸音层36和隔音层37使隔声罩3具有较好的吸声和隔声的效果，避免制动器11产生的空气噪声从容纳空间33传播到车内或车 外。
在本申请的一些实施例中，支撑层34可以为玻璃钢件等。如此设置，使支撑层34具有一定的刚度，能够起到支撑作用的同时，还具有一定的弹性，方便安装。另外，如此设置的支撑层34具有质量轻、成本低、防火性能好等特点。当然，本申请不限于此，支撑层34还可以为铝合金件、不锈钢件等。
在本申请的一些实施例中，吸音层36可以为发泡橡胶层。但不限于此。由此，吸音层36可以对空气噪声例如中低频噪声产生较好的吸音效果，从而进一步降低车内噪声和车外噪声。
在本申请的一些实施例中，隔音层37可以为重质隔音层37(指由质量较重、密度较高的隔音材料制成的隔音层37)例如EVA(ethylene-vinyl acetate copolymer，指的是“乙烯-醋酸乙烯共聚物”及其制成的橡塑发泡材料)层或丁腈橡胶层等。但不限于此。如此设置，隔音层3728具有很好的隔音效果，从而使隔声罩3可以有效隔绝制动器11产生的空气噪声。
在本申请的一些实施例中，第二罩体32与横向止挡2可拆卸地相连。例如，第二罩体32的上端与横向止挡2可以通过螺纹紧固件例如螺栓实现无缝连接。这样，在保证第二罩体32与横向止挡2之间的密封可靠性的同时，方便装拆。
参照图10所示，根据本申请第二方面实施例的轨道车辆200，包括根据本申请上述第一方面实施例的转向架100。
根据本申请实施例的轨道车辆200例如跨座式单轨车辆，通过采用上述的转向架100，可以很好地隔绝制动器11产生的空气噪声，从而有效降低车内噪声和车外噪声。
根据本申请实施例的轨道车辆200的其他构成以及操作对于本领域普通技术人员而言都是已知的，这里不再详细描述。
在本申请的描述中，需要理解的是，术语“中心”、“纵向”、“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”、“轴向”、“径向”、“周向”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。
