Description

一种跨座式单轨车构架及其转向架 技术领域
本发明属于轨道交通领域，具体涉及一种跨座式单轨车构架及其转向架。
背景技术
跨座式单轨转向架目前主要有两种结构形式，一种是每个转向架配备两根车轴，每根车轴安装两个走行轮的双轴式转向架；另外一种是每个转向架配备一根车轴，每轴安装两个走行轮的单轴式转向架。无论双轴还是单轴，跨坐式转向架均需配置导向轮与稳定轮。一般导向轮为四个，轨道梁的两侧各两个，夹住轨道梁的上半部分。稳定轮为两个或者四个，夹住轨道梁的下半部分。导向轮、稳定轮与走行轮一起从三个方向抱住轨道梁，以保持车辆稳定运行。
在现有技术中，跨座式单轨车构架一般采用“日”字形结构，由侧梁、横梁与端梁组成，侧梁用于安装导向轮、稳定轮及驱动装置，横梁用于安装中心销、牵引装置与横向悬挂装置，端梁用于安装紧急轮。为了便于轮胎的安装与拆卸，一般采用悬臂式车轴，悬臂式车轴与构架的连接是构架设计的难点，另外悬臂式车轴对轴承选型提出了更高的要求。
中国专利ZL201520516445.5公开了一种单轨动力转向架构架，构架由横梁、侧梁及端梁组成，构架侧梁与端梁的连接部分设置四个导向轮安装座，在侧梁底部向下延伸一根悬臂用于安装导向轮。电机安装方向与侧梁平行，车轴安装孔位于侧梁的一端，与另一根侧梁成斜对称布置。
中国专利ZL201620580467.2公开了一种单轨车转向架，该专利的构架与专利ZL201520516445.5基本类似。
包括上述所引专利在内的现有技术的构架及转向架主要存在如下缺陷：
1.对于双轴式单轨转向架，其牵引电机一般与驱动轴成90°角度布置，需要设置锥齿传动，影响传动效率。
2.抗侧滚能力差，影响车辆运行的平稳性和舒适性。
3.转向架结构复杂且布局不合理，空间不够优化。
另外，对本案中所提到的方向词汇进行定义，在轨道车辆领域中，技术人员通常认定的方向有三种：
垂向：竖直垂直于轨面的方向。
纵向：沿着轨道的方向。
横向：水平垂直于轨道的方向。
发明内容
针对上述问题，本发明旨在提供结构简单紧凑、传动效率高，能保证车辆运行的安全性及平稳性的跨座式单轨车构架及其转向架。
本发明解决问题的技术方案是：一种跨座式单轨车构架，包括具有竖直部的一对侧梁、同时与两根侧梁的竖直部上端连接的横梁；
在每一根侧梁和横梁连接区域的纵向端面上均设有一个驱动装置安装座，且两个驱动装置安装座相对于横梁的垂向中心轴线对称；
所述驱动装置安装座的外侧设有牵引电机安装凸台、内侧设有车轴安装凸台，牵引电机安装凸台上设有轴孔，该轴孔与横梁平行，且贯通至车轴安装凸台。
上述方案中，采用类似于龙门形状的构架代替传统的日字形构架，结构更简单且紧凑，减少了零部件数量。其驱动装置安装座结构及位置做了重大改进，使得驱动装置安装位置更合理、更紧凑。
进一步的，所述横梁内设有贯通的第一中空腔，第一中空腔内穿设有安装梁，该安装梁的两端从第一中空腔内伸出，且安装梁内设有贯通的第二中空腔；
在安装梁伸出第一中空腔的区域段上设有牵引杆连接座。
优选的，所述驱动装置安装座内设用于布置联轴节的第四中空腔。
优选的，所述侧梁为箱型结构，在侧梁中部设有受流器安装孔。传统构架结构用于安装受流器的结构往往需要额外向下延伸一根臂梁，然后在臂梁内侧面安装受流器。改进后的构架直接在侧梁上即可安装受流器，结构更紧凑。
进一步的，所述侧梁还包括与竖直部垂直的水平部，在每一根侧梁的水平部两端的上表面均设有导向轮安装座，在每一根侧梁的水平部两端的下表面均设有稳定轮安装座；
在横梁两端顶部分别设有空簧安装座；在横梁顶部中间部位设有横向止档及横向减振器安装座。
倒T字形的侧梁包括水平部和与水平部垂直的竖直部。水平部与竖直部衔接处圆弧过渡。
相应的，本发明还提供一种转向架，包括走行轮、牵引电机、车轴以及上述跨座式单轨车构架；
在牵引电机安装凸台上固定安装有牵引电机，牵引电机的输出轴插入轴孔内；
所述车轴包括一端与车轴安装凸台固定连接的带第三中空腔的悬臂轴、设置于第三中空腔内的第一传动轴和第二传动轴，第一传动轴和第二传动轴近端之间通过齿轮副一级传动，第一 传动轴的一端插入轴孔内并与牵引电机的输出轴对接，第二传动轴的远端设有行星轮，该行星轮通过旋转筒与走行轮的轮毂连接，旋转筒内壁与悬臂轴外表面之间通过轴承支撑连接。
上述方案中，取消了传统的锥齿传动方式，将原有的悬臂式车轴进行结构改进，在车轴中内置一套传动系统，并将牵引电机输出轴和车轴布置在同一个方向，在提高传动效率的同时，使得驱动装置与车轴紧靠，整个驱动系统装配更紧凑。
优选的，所述驱动装置安装座内设用于布置联轴节的第四中空腔，第一传动轴与牵引电机的输出轴通过联轴节连接。
进一步的，所述侧梁还包括与竖直部垂直的水平部，在每一根侧梁的水平部两端的上表面均设有导向轮安装座，导向轮安装座上安装有导向轮，导向轮的轴线沿垂向；
在每一根侧梁的水平部两端的下表面均设有稳定轮安装座，稳定轮安装座上安装有稳定轮，稳定轮的轴线沿垂向；
在横梁两端顶部分别设有空簧安装座，空簧安装座上安装有空簧；
在横梁顶部中间部位设有横向止档及横向减振器安装座，横向减振器安装座上设有横向减振器。
进一步的，所述横梁内设有贯通的第一中空腔，第一中空腔内穿设有安装梁，该安装梁的两端从第一中空腔内伸出，且安装梁内设有贯通的第二中空腔；
在安装梁伸出第一中空腔的区域段上设有牵引杆连接座，该牵引杆连接座上安装有牵引杆；在横梁两端顶部分别设有空簧安装座，空簧安装座上安装有空簧；
还包括抗侧滚装置，抗侧滚装置包括横向穿设并固定于第二中空腔内的扭杆、与扭杆两端通过轴承连接的连杆、以及拉压杆；所述拉压杆上端与空簧顶部铰接、下端与连杆铰接。
传统的跨座式单轨车由于空间的局限并没有安装抗侧滚装置，导致抗侧滚能力差。本发明改进后的结构由于合理的利用了构架空间，加装了抗侧滚装置，提高了辆运行的平稳性和舒适性。
进一步的，所述侧梁为箱型结构，在侧梁中部设有受流器安装孔，受流器安装孔内安装有受流器。
本发明的显著效果是：
1.取消了传统的锥齿传动方式，将原有的悬臂式车轴进行结构改进，在车轴中内置一套传动系统，并将牵引电机输出轴和车轴布置在同一个方向，在提高传动效率的同时，使得驱动装置与车轴紧靠，整个驱动系统装配更紧凑。
2.采用类似于龙门形状的构架代替传统的日字形构架，结构更简单且紧凑，减少了 零部件数量，降低了成本。
3.加装了抗侧滚装置，减小了车辆在运行中晃动，提高了辆运行的平稳性和舒适性。
