Description

一种悬挂式单轨列车及其转向架、驱动制动装置 技术领域
本发明涉及一种悬挂式单轨列车及其转向架、驱动制动装置，属于悬挂式单轨交通列车设计领域。
背景技术
单轨列车的轨道与传统轨道交通列车的轨道不同，单轨列车的轨道只有一条，且车轮大多数采用橡胶轮胎。悬挂式单轨列车是单轨列车的一种，其转向架位于车体的上方，车体悬挂在转向架上。相对于传统钢轮、钢轨轨道交通系统，悬挂式单轨列车的优缺点都比较明显，其适用于地理、气候条件不具备修建轻轨、地铁系统的地区，也可作为城市轨道交通线路的辅助支线或旅游景区的观光游览线。
传统的轨道交通列车通过对车轮踏面的特殊设计实现车辆在轨道上自导向走行，悬挂式单轨列车由于采用了常规的橡胶轮胎作为走行轮，走行轮不再具备自导向能力，因此需要在转向架上设置专门的导向轮实现车辆的自导向。由于车体吊挂在转向架上，因此在转向架上需要设置专门的牵引悬挂装置实现车体和转向架之间力的传递。为了实现列车的牵引和制动，转向架上需要有受流器、驱动装置、基础制动装置等主要部件。
对于在箱型轨道梁中走行的悬挂式单轨列车转向架，由于箱型轨道梁结构尺寸受到路基的限制，转向架的横向尺寸和质量也受到限制，所以在设计转向架时转向架的结构紧凑和轻量化也是要解决的技术问题。
发明内容
本发明旨在提供一种悬挂式单轨列车及其转向架、驱动制动装置，该驱动制动装置可以实现模块化设计，且结构紧凑，从而可以提高装配的稳定性及列车运行的安全性。
为了实现上述目的，本发明所采用的技术方案是：
一种悬挂式单轨列车的驱动制动装置，其结构特点是，包括牵引电机、联轴节、齿轮箱、第一基础制动装置和第二基础制动装置；
所述牵引电机与齿轮箱联接在一起，该牵引电机的输出轴与齿轮箱的输入轴之间通过联轴节联接；
所述第一基础制动装置安装在齿轮箱箱体上，所述第二基础制动装置安装在走行轮的轮毂上。
所述走行轮安装在齿轮箱的输出轴上。
这样，本发明创造性地将驱动装置和基础制动装置集成在了一起，形成了整体式的驱动制动装置，提高了装配的稳定性，进而提高了列车运行的安全性。
本发明提高整个转向架的系统集成度，降低部件安装复杂度，基础制动装置不安装在构架上，而集成在驱动装置的齿轮箱上，去掉了常规转向架构架上的基础制动装置安装座，有利于转向架构架结构简化，提高了构架强度。
根据本发明的实施例，还可以对本发明作进一步的优化，以下为优化后形成的技术方案：
根据本发明的一种优选实施例，所述第一基础制动装置为制动夹钳；所述第二基础制动装置为轮盘制动。
通常轨道交通车辆采用两种制动方式，踏面制动和轮盘制动，踏面制动 用于钢轮、钢轨车辆，本发明所述悬挂式单轨车是采用的橡胶轮胎(与汽车轮胎相似)，汽车系统所用的制动系统分盘式制动和鼓式制动两种，在输出制动力矩相同的情况下，盘式制动尺寸和质量一般较小，而悬挂式单轨车转向架位于箱型轨道梁内，空间有限，要求转向架结构紧凑，本发明采用了盘式制动，制动夹钳是与轮盘配合使用。
优选地，所述悬挂架设置在箱型轨道梁的底部下方，所述悬挂杆从悬挂式单轨列车的转向架的中间穿过。由此，悬挂架设置在箱型轨道梁的底部下方，不设置在箱型轨道梁内，这样空气弹簧可以纵向布置，悬挂杆从转向架中间穿过，从而进一步降低了转向架的宽度。
基于同一个发明构思，本发明还提供了一种悬挂式单轨列车的转向架，其包括构架，安装在构架上的导向轮、走行轮、受流器和所述的驱动制动装置；所述驱动制动装置纵向对称布置在构架上；所述受流器安装在构架的上端部；所述走行轮直接安装在齿轮箱的输出轴上，并由所述驱动制动装置的牵引电机驱动。
为了提高悬挂式单轨列车的安全性能，所述构架上安装有安全辅助装置，该安全辅助装置用于在当走行轮失效时承担整个列车的重量。
优选地，所述构架上设有用于安装齿轮箱的齿轮箱安装座，该齿轮箱兼做传递扭矩和传递走行轮和构架之间的垂向力和纵向力。
传统的轨道交通车辆(钢轮、钢轨车辆)齿轮箱的作用是传递扭矩，传递车轮和构架之间的垂向力和纵向力是通过轴箱实现，本发明中的齿轮箱相当于将传统轨道交通车辆转向架上的齿轮箱和轴箱集成在了一起，同时具备了齿轮箱和轴箱的功能，使得转向架结构简单紧凑。
本发明创造性地将电机悬臂安装在齿轮箱上，同时将驱动装置和制动装置集成在了一起，避免了再在电机上安装制动装置导致电机安装螺栓受力情况恶劣。
优选地，所述构架上设置有二系悬挂座，该二系悬挂座用于安置空气弹簧。
基于同一个发明构思，本发明还提供了一种悬挂式单轨列车，其包括转向架和车体，该转向架与车体之间通过牵引悬挂装置联结；其结构特点是，所述转向架为带动力转向架，其用于行走在箱型轨道梁中；所述转向架为所述的悬挂式单轨列车的转向架。
本发明的悬挂式单轨列车由于位于空中，箱型轨道梁的尺寸受限(太大会造成成本增加和对视觉空间造成影响)，所以对转向架的紧凑性要求较高，在满足功能的前提下，转向架的结构需要尽量简单紧凑。
由于将驱动装置和基础制动装置集成在了一起，且齿轮箱兼具传统轨道交通车辆转向架上的齿轮箱和轴箱的作用，因此整个转向架装配稳定性提高，转向架结构简单紧凑，在同样的外形尺寸(受箱型轨道梁尺寸限制)要求下，转向架的安全性和承载能力显著提供，从而提高了列车运行的安全性。此外，本发明中的牵引悬挂装置在实现转向架和车体之间联接的同时，可以保证转向架结构足够紧凑。
优选地，所述牵引悬挂装置包括竖直穿过构架的悬挂杆、用于连接车体的悬挂架、设置在悬挂架和悬挂杆上的减振器座；所述悬挂杆顶端通过二系悬挂装置与转向架相连。
优选地，所述构架的中心位置开有竖向设置的悬挂杆安装孔，该悬挂杆 安装孔与悬挂杆配合用于传递转向架和车体之间的纵向力和横向力。
本发明的设计难点在于转向架适用于大轴重(8.5t)，高速(80km/h)，而通常的转向架只适用于轴重小于5t，速度小于60km/h。同时，由于箱型轨道梁的尺寸受到限制，因此本发明的转向架做的非常紧凑，集成度很高。
与现有技术相比，本发明的有益效果是：
本发明将驱动装置和基础制动装置集成在了一起，形成驱动制动装置，实现了模块化设计，提高了装配的稳定性，进而提高了列车运行的安全性。
此外，驱动制动装置纵向对称布置，使得走行轮轴距可以尽可能短，从而可以减少导向力，同轴上两走行轮距离设置较宽以减少车辆倾斜。
最后，本发明的结构独特的牵引悬挂装置在实现转向架和车体之间联接的同时，可以保证转向架结构足够紧凑。

图1、图2、图3所示为本发明所述的悬挂式单轨列车，包括转向架和车体，转向架与车体之间通过牵引悬挂装置2.4联结。转向架为带动力转向架，在箱型轨道梁中运行，车体悬挂在其下方。
如图2、图3、图7所示，牵引悬挂装置2.4为车体与构架2.6之间的传力部件，并承受车体与转向架之间的相对运动和冲击。牵引悬挂装置2.4主要由设置在上部的空气弹簧2.4.1、竖直穿过构架2.6上悬挂杆安装孔2.6.3的悬挂杆2.4.2、连接车体的悬挂架2.4.3、设置在悬挂架2.4.3和悬挂杆2.4.2上的减振器座2.4.4构成。空气弹簧2.4.1传递垂向力并控制车辆地板面高度，减振器座2.4.4上安装减振器，悬挂架2.4.3与车体之间通过专用螺栓连接。
转向架主要由导向轮2.1、走行轮2.2、受流器2.3、牵引悬挂装置2.4、驱动制动装置2.5、构架2.6、安全辅助装置2.7组成。构架2.6用来联系转向架各组成部分和传递各方向的力，安装在构架2.6上的安全辅助装置2.7在当走行轮2.2失效时承担整个车辆重量，在紧急情况下确保车辆安全。在构架2.6的8个端角位置安装导向轮2.1，实现转向架的自导向功能，导向轮2.1为橡胶轮胎，承受 车辆和箱型轨道梁之间的横向力。在构架2.6的上端部安装受流器2.3，受流器2.3接受外界电流输入。转向架上有4个走行轮2.2，走行轮2.2为充气橡胶轮胎，直接安装在齿轮箱2.5.3的输出轴上，走行轮2.2传递车辆与轨道间的牵引力和制动力，并承担整车质量。
如图4所示，本发明中构架2.6采用钢板焊接结构，在构架2.6上设置二系悬挂座2.6.1和齿轮箱安装座2.6.2，该二系悬挂座2.6.1用于安置空气弹簧2.4.1，该齿轮箱安装座2.6.2用于安装齿轮箱2.5.3，构架2.6上的悬挂杆安装孔2.6.3与悬挂杆2.4.2配合，传递转向架和车体之间的纵向力和横向力。
一种悬挂式单轨列车的驱动制动装置，包括集成在一起的驱动装置和制动装置；所述驱动制动装置2.5包括牵引电机2.5.1、联轴节2.5.2、齿轮箱2.5.3、第一基础制动装置2.5.4和第二基础制动装置2.5.5；所述牵引电机2.5.1与齿轮箱2.5.3联接在一起，该牵引电机2.5.1的输出轴与齿轮箱2.5.3的输入轴之间通过联轴节2.5.2联接；所述齿轮箱2.5.3的输出轴上用于安装走行轮2.2；所述第一基础制动装置2.5.4安装在齿轮箱2.5.3箱体上，所述第二基础制动装置2.5.5安装在走行轮2.2的轮毂2.5.6上。
如图2、图3、图5、图6所示，本发明将驱动装置和制动装置集成在一起，文中简称驱动制动装置2.5。驱动制动装置2.5主要由牵引电机2.5.1、联轴节2.5.2、齿轮箱2.5.3、第一基础制动装置2.5.4(夹钳)、第二基础制动装置2.5.5(轮盘)组成。牵引电机2.5.1通过螺栓和齿轮箱2.5.3联接在一起，牵引电机轴与齿轮箱输入轴之间通过联轴节2.5.2联接，联轴节2.5.2传递牵引电机的输出力矩到齿轮箱上。齿轮箱2.5.3通过螺栓安装在构架2.6的齿轮箱安装座2.6.2上，这样，齿轮箱2.5.3不仅起到减速增扭的作用，还起到了传递走行轮2.2和 构架2.6之间的垂向力和纵向力的作用。走行轮2.2直接安装在齿轮箱2.5.3的输出轴上，第二基础制动装置2.5.5(轮盘)安装在走行轮2.2的轮毂2.5.6上，第一基础制动装置2.5.4(夹钳)安装在齿轮箱2.5.3箱体上。
上述实施例阐明的内容应当理解为这些实施例仅用于更清楚地说明本发明，而不用于限制本发明的范围，在阅读了本发明之后，本领域技术人员对本发明的各种等价形式的修改均落入本申请所附权利要求所限定的范围。
