Description
本发明涉及到测功机技术领域，具体涉及到多环境系统下重载、大功率、大扭矩底盘测功机。
底盘测功机是一种用来测试汽车及工程车辆动力性、多工况排放指标、燃油指标、纯电续航里程等性能的室内台架试验设备，底盘测功机通过滚筒模拟路面，计算出道路模拟方程，并用加载装置进行模拟，实现对汽车及工程车辆各工况的准确模拟，它可用于汽车及工程车辆的加载调试，诊断车辆在负载条件下出现的故障；底盘测功机使用方便，性能可靠，不受外界条件的影响。在不解体汽车的前提下，能够准确快速地检测出汽车各个系统、部件的使用性能。底盘测功机既可以用于汽车科学试验，也可以用于维修检测。
如中国实用新型专利(公开号：CN201212854)在2009年公开了一种转毂底盘测功机，包括支架和对称布置在转毂前后两侧的举升对中推进机构，各举升对中推进机构均由左右对称布置的丝杠、丝母及推臂组成，丝杠可转动地安装在支架上，推臂前端之间设有横向的小支撑滚筒，后端与丝母相连接，并在前后两端均安装有滚轮，与支架上的轨道相配合，轨道中部向上拱起呈弧形，各举升对中推进机构相对应的丝杠同轴连接，其动力输入端分别与支架外侧的减速机输出端相连接，减速机由电机统一驱动。该装置能使车轮精确定位并摆正，且具有举升和保护功能，可用于汽车转毂试验台。但是这种测功机的传动结构复杂，扭矩和功率很难有较大的提升，而且不适合重载卡车、大型车辆的测功。
另外现有的测功机的灵活性较差，不能够根据不同轴距调整前后转毂的中心距，对于多种型号的车辆需要多套测功系统。
发明内容
本发明的目的是针对现有技术存在的问题，提供多环境系统下重载、大功率、大扭矩底盘测功机。

所述第一转毂组件分别包括第一转毂，以及与所述第一转毂同轴设置的第一传动轴，所述第一传动轴的一端伸入所述第一转毂内并与所述第一转毂连接、另一端向外延伸并设有端部法兰盘，所述端部法兰盘上设有若干制动组件；所述第一传动轴靠近所述第一转毂的一侧套设有第一驱动组件，所述第一驱动组件的轴向两侧分别设有轴承组件；

将所述拉力传感器组件设置在驱动组件的外侧，既能够支撑驱动组件，也能够直接获取转毂受压传递过来的受力；所述制动组件能够提供制动，以控制传动轴的旋转速度或者停止传动轴和转毂的转动。
将所述第一转毂组件和所述第二转毂组件设置在所述测功平台的下方(即地下)，只露出一小部分的外圆周在所述测功平台上方(即地面部分)，一方面便于车辆直接从所述测功平台上开上这些转毂上，另一方面也能够避免转毂内部的组件以及所述测功平台下方的其它部件暴露在地面上的环境实验仓中，减少环境实验仓中环境系统的模拟对测功机本身的驱动和传动系统造成影响，以减少和降低试验测试误差。

本测功机具有重载、大功率、大扭矩的特点，通过一对固定位置的第一转毂组件6和一对滑动设置的第二转毂组件7的设置，使得两组转毂组件的中心距可以调节，以适配不同重载卡车的底盘测功测试，能够对多组前轮进行测试，也能够对前后轮同步进行测试，测功的适用范围较广；而且每个转毂组件分别设置有驱动组件、制动组件14和拉力传感器组件13，使得测试时能够对每个车轮进行单独测试，也可以联动测试、差速测试，以全方面的获取车轮及底盘的性能和数据；结合多环境实验仓的设置，能够模拟不同温度、不同湿度、不同气压下的环境系统，更加准确的反映待测车辆的性能。
所述滑动底座4和所述滑动平台5的设置，能够整体同步的带动同轴设置的一对所述第二转毂组件7滑动，以调节与所述第一转毂组件6的间距，调节范围能够达到3000-8500mm，也就是最小间距小于或者等于3000mm，最大间距超过8500mm。
由于对重载卡车底盘测试用的转毂的尺寸较大，通过本结构的设置基本将每个驱动组件设置在转毂的内部，能够明显减小轴向尺寸，而且缩短了传动轴的长度，只需通过轴承组件9以及电机安装座11就能够实现所述传动轴和转毂的安装，结构十分紧凑，在缩短轴向尺寸的同时也能够保证足够的支撑能力。
将所述拉力传感器组件13设置在驱动组件的外侧，既能够支撑驱动组件，也能够直接获取转毂受压传递过来的受力；所述制动组件14能够提供制动，以控制传动轴的旋转 速度或者停止传动轴和转毂的转动。
将所述第一转毂组件6和所述第二转毂组件7设置在所述测功平台1的下方(即地下)，只露出一小部分的外圆周在所述测功平台上方(即地面部分)，一方面便于车辆直接从所述测功平台1上开上这些转毂上，另一方面也能够避免转毂内部的组件以及所述测功平台下方的其它部件暴露在地面上的环境实验仓中，减少环境实验仓中环境系统的模拟对测功机本身的驱动和传动系统造成影响，以减少和降低试验测试误差。
进一步的，结合图3～6所示，所述轴承组件9包括套设在所述第一驱动组件603或者所述第二驱动组件703外壳体两端上的主轴承，所述主轴承安装在所述电机安装座11的轴向两端并分别在内外两侧设有轴承端盖901，所述轴承端盖901分别抵接并螺接在所述电机安装座11上，所述轴承端盖901之间还设有轴承压板902，所述轴承压板902为弓形、两端分别螺接在所述电机安装座11上。所述轴承压板902的设置能够进一步将所述轴承端盖901固定在所述电机安装座11上，减少轴向的波动。
进一步的，所述第一转毂601和所述第二转毂701均包括外轮廓形状相同并且外径相等的转毂本体，所述转毂本体的内圆周上设有安装端面15，所述安装端面15的中部设有阶梯状的连接套16，所述连接套16内套设有第一胀紧套17，所述第一胀紧套17套设有所述第一传动轴602或者所述第二传动轴702的端部；所述转毂本体的内圆周上还设有若干圈周向加强筋19，在所述第一转毂组件6中，由于所述第一驱动电机的尺寸和功率更大，占用的空间更多一些，所述安装端面15不是设置在中部位置，所述周向加强筋19与所述安装端面15对称设置；在所述第二转毂组件7中，所述安装端面15设置在中部位置，所述周向加强筋19为一对分别对称设置在所述安装端面15的两侧；
所述安装端面15上还设有若干轴向贯穿的通孔。所述第一传动轴602和所述第二传动轴702的轴线处于同一水平面内。
采用这个结构的转毂本体在兼顾较大尺寸的外圆周的同时，也能够合理利用内部空间以安装其它部件，由于所述第一驱动组件603和所述第二驱动组件703的功率和尺寸不同，但是为了保证轮距和中心距，所述转毂本体内的安装端面15设置的位置会有差异；所述周向加强筋19的设置，能够进一步的提高转毂本体的强度和平衡性能。
同轴设置的所述第一转毂组件6或者所述第二转毂组件7的转毂本体的同轴度小于或等于0.5mm，前后设置的所述第一转毂组件6和所述第二转毂组件7的转毂本体的中心轴平行度小于等于1mm。

进一步的，所述侧板802为多级阶梯状梯形板，所述侧板802的上部尺寸小于所述侧板802的下部尺寸，采用这种形状的侧板802，能够增加下方的支撑面积、减少上方的空间占用，能够让上方的部件连接更加紧凑，将中心落在所述基板801中线所在平面内，稳定性更好；所述电机安装座11为半圆形槽状结构，所述第一驱动组件或者所述第二驱动 组件分别设置在所述电机安装座11中；所述电机安装座11的外圆周靠近所述侧板的两侧均设置为平面结构1102并紧密抵接所述侧板802的内侧，所述电机安装座11的外圆周靠近所述侧板802的阶梯处设有凹槽1101，这个地方能够空出来连接和安装所述拉力传感器组件13。
