Description

搅拌车及其驱动改造方法 技术领域
本发明涉及搅拌车领域，尤其涉及一种搅拌车及其驱动改造方法。
背景技术
搅拌车，指的是混凝土搅拌车，是用来运输建筑用混凝土的专用卡车，这类卡车上通常配备能量回收系统、车载空调和搅拌上装等，其中：
搅拌上装是由发动机驱动的，耗油高。并且搅拌车停在工地上执行搅拌工作、甚至停车等待时，搅拌罐对应的发动机不能熄火，并且必须低速且匀速运转，以持续输出驱动上装旋转动力，因此增加了油耗。针对上述问题，现有技术中存在通过电机驱动上装转动，使得上装转动的驱动力不在依赖于发动机，从而有效降低油耗，但是传统电机与搅拌车上原有的减速箱连接时，存在以下缺陷：
第一，传统电机的自重较大，且轴向尺寸较长，因此采用传统电机与搅拌车上原有的减速箱连接时，原有减速箱的外壳体无法承受电机自重所带来的弯矩和剪力，容易出现破裂等现象，必要时需重新设计，甚至更换为与传统电机匹配的新减速箱外壳体，或者采用减速一体化电机来完全取代原有减速箱。
第二，即便传统电机额外增加支撑底座以承担其自重，当上装变速旋转时，依然存在震动和窜动的问题，不能完全消除其自重带来的影响。
可见，上述两种技术方案均存在改造成本高、需要重新设计电机支撑、调试安装繁琐的问题。
能量回收系统是为了回收车辆制动时的动能，但是由于搅拌车车体较大，以及车头较大，导致采用传统电机作为发电机时，存在自重带来的弯矩和剪力问题。与搅拌上装相同，由于传动发电机的轴向尺寸较长，且自重较大，使得整体长度过长，同样引发上述缺陷，甚至缩短使用寿命。
车载空调用于对搅拌车上的驾驶室进行制冷，目前车载空调均为发动机驱动的，油耗高。

具体实施方式
以下描述用于揭露本发明以使本领域技术人员能够实现本发明。以下描述中的优选实施例只作为举例，本领域技术人员可以想到其他显而易见的变型。在以下描述中界定的本发明的基本原理可以应用于其他实施方案、变形方案、改进方案、等同方案以及没有背离本发明的精神和范围的其他技术方案。
如图1所示，一种搅拌车的驱动改造方法，所述方法改造搅拌车的至少一驱动设备，包括以下步骤：
(a)拆除所述驱动设备的原连接端112a、112b所连接的油驱动；
(b)直接地连接盘式电机120a、120b至所述驱动设备的所述原连接端112a、112b，并将所述盘式电机120a、120b支承于所述驱动设备的原壳体111a、111b。
所述驱动改造方法是在搅拌车的原驱动设备的基础上，拆除油驱动(例如液压驱动的发动机等)，并置换成所述盘式电机120a、120b，以有效减少耗油量。并且所述盘式电机120a、120b能够直接利用驱动设备上的原连接端112a、112b进行连接，无需增设额外结构，使得改造过程更加简便，而且同时降低改造成本。另外所述盘式电机120a、120b具有轴向尺寸小，重量更轻等特点，并且所述盘式电机120a、120b直接支承在原壳体111a、111b上，相对于传统径向电机来说，使得所述原壳体111a、111b能够承担盘式电机120a、120b自重所带来的弯矩和剪力，长期运行也不会发生变形和开裂，因此无需增设新的支撑结构，并且避免重新设计原壳体或减速一体化电机，有效降低成本，延长使用寿命，以及简化安装调试等过程。
以下为相同功率下的径向电机和盘式电机的比较表：
Figure PCTCN2022114715-appb-000001
其中，120kW的传统径向电机的轴向尺寸和重量，均大于所述120kW盘式电机，参考图1，所述传统径向电机是在水平方向上延伸设置，此时所述传统径向电机的重心离所述原壳体111a、111b较远，使得电机弯矩较大。而所述盘式电机轴向尺寸较小，相对于传统径向电 机，其仅在竖直方向上延伸设置，使得所述盘式电机的重心离所述原壳体111a、111b较近，使得电机弯矩更小，有效提高电机安装稳定性，降低所述原壳体111a、111b负载。
如图1、图6和图7所示，所述驱动设备可以为搅拌上装200、能量回收系统300和空调系统400等，以将油驱动更改为电驱动，以降低耗油量。并且采用轴向尺寸较小，重量轻的盘式电机，以无需额外增设支撑，降低成本，并且降低原壳体对电机的负载，延长使用寿命。
如图1至图3所示，当所述驱动设备为搅拌上装200时，所述搅拌上装200包括盘式电机120a、减速箱和搅拌罐210，所述减速箱包括第一原壳体111a，以及被所述第一原壳体111a暴露的第一原连接端112a，所述盘式电机120a支承于所述第一原壳体111a上，且与所述第一原连接端112a相连接，所述方法包括：
所述盘式电机120a被支承于所述搅拌上装200的减速箱，以使所述盘式电机120a能够电驱动所述搅拌上装200的搅拌罐210。
其中所述第一原壳体111a作为所述减速箱的壳体，所述第一原连接端112a作为所述减速箱的输入端，而减速箱的输出端连接所述搅拌罐210，因此当所述盘式电机120a连接所述第一原连接端112a后，所述盘式电机120a就能电驱动所述搅拌罐210转动。
所述第一盘式电机120a能够直接连接所述减速器的输入端，并支承于所述减速器的壳体表面。所述搅拌上装200固定于所述搅拌车的底盘700上，且位于驾驶室500的后方，其中所述底盘700水平设置，而所述搅拌上装200相对所述底盘700倾斜设置，当然两者也可大致水平。所述盘式电机120a取代现有的液压发动机，降低油耗，能够直接利用原驱动设备上的第一原连接端112a进行连接，无需增设额外结构，使得改造过程更加简便，而且同时降低改造成本，以及相对传统径向电机，还保证所述第一原壳体111b的支撑能力。
如图1和图6所示，当所述驱动设备为能量回收系统300时，所述能量回收系统300包括盘式电机120b、取力器和发动机310，所述取力器包括第二原壳体111b，以及被所述第二原壳体111b暴露的第二原连接端112b，所述盘式电机120b为盘式发电机，所述盘式电机120b支承于所述第二原壳体111b上，且与所述第二原连接端112b相连接，所述方法包括：
所述盘式电机120b被支撑于所述能量回收系统300的取力器，以使所述盘式电机120b回收发动机310的能量，并为电池440充电。
所述第二原壳体111b作为取力器的壳体，所述第二原连接端112b可以为取力器的输入端，而取力器的输出端连接所述发动机310，这样所述盘式电机120b能够直接连接所述取力器的输入端，并支承于所述取力器的壳体表面。其中所述盘式电机120b作为发电机，位于所 述底盘700上，且布置所述驾驶室500的后方，以取代液压驱动，不仅降低油耗，能够直接利用原驱动设备上的第二原连接端112b进行连接，还同时保证所述第二原壳体111b对所述盘式电机120b的支撑能力，以及延长使用寿命。
进一步说明，所述取力器包括依次连接的取力器本体、输出轴和法兰盘，此时所述盘式电机120b固定于所述法兰盘上，即所述法兰盘为所述第二原壳体111b。
继续参考图6，所述能量回收系统还包括万向节320，所述万向节320连接于所述发动机310和所述取力器之间。
如图7所示，当所述驱动设备为空调系统400时，所述方法还包括：
将所述电池440接入所述空调系统400的压缩机430，以为所述压缩机430工作提供电能。
所述电池440为所述压缩机430工作提供电能，进一步节约油耗，并且所述搅拌上装200和所述空调系统400等为独立电驱动，因此在使用所述空调系统400时，所述搅拌车可以熄火，起到节能环保的作用。另外所述电池440还可为所述第一盘式电机120a提供电能，可见所述电池440可同时对所述空调系统400和所述搅拌上装200供电。当然所述电池440可由外部电源供电。
所述空调系统400可为搅拌车原有的车载空调系统，也可为原车载空调上进行改造的空调系统。
综上，所述搅拌车的搅拌上装200、能量回收系统300和所述空调系统400均可采用上述改造方法进行改造，即在原驱动设备的基础上，利用所述盘式电机取代油驱动，并且所述空调系统400可采用电驱动，能够较大程度的节约油耗。并且因盘式电机轴向尺寸小，重量轻等特点，无需额外增设支撑，降低成本，并且降低原壳体对电机的负载，延长使用寿命。另外在盘式电机取代油驱动的改造过程中，能够直接利用原驱动设备的原连接端112a进行连接，无需增设额外结构，使得改造过程更加简便，而且同时降低改造成本，更适合用于市场上现有燃油搅拌车的电驱改造。
如图1所示，所述原壳体111a、111b具有一支承面1111，所述原连接端112a、112b被所述支承面1111暴露，进而所述方法包括：
将所述盘式电机120a、120b与所述支承面1111大致平行且贴合的方式，连接于所述原连接端112a、112b。
其中所述盘式电机120a、120b轴向尺寸小，因此所述盘式电机120a、120b的两个端面平行，并且两者之间界定的距离较小，而所述盘式电机120a、120b朝向所述支承面1111 的端面，其与所述支承面1111平行贴合，保证了两者的效接触支承，提升所述原壳体111a、111b对所述盘式电机120a、120b的支撑能力。
如图1、图4和图5所示，所述步骤(b)进一步包括步骤：
(b1)提供连接盘130，所述连接盘130具有大致平行的结构连接面131和电机连接面132；
(b2)将所述原壳体111a、111b连接于所述结构连接面131；
(b3)固定所述盘式电机120a、120b至所述电机连接面132。
所述连接盘130起到连接所述盘式电机120a、120b和所述原壳体111a、111b的作用，并保证两者连接稳定，防止两者分离而影响电机的可靠性。所述结构连接面131和所述电机连接面132之间的距离，其界定了所述连接盘130的轴向尺寸。而所述连接盘130和所述盘式电机120a、120b均呈扁平结构(即轴向尺寸小)，因此有效缩短所述盘式电机120a、120b至所述支承面1111之间的距离，避免电机弯矩过大而使所述原壳体111a、111b无法支撑电机。另外所述盘式电机120a、120b和所述连接盘130的外周可齐平，保证两者的接触面积，以提升结合的稳定能力，并且所述连接盘130的外周可位于所述支承面1111围成的区域内，即所述盘式电机120a、120b朝向的所述支承面1111的端面，其均内被有效接触支承，提升所述原壳体111a、111b对所述盘式电机120a、120b的支撑能力。
所述连接盘130还具有贯穿所述结构连接面131和所述电机连接面132，且用于所述紧固件通过的安装孔133a、133b。所述紧固件可以为螺栓等，其可分为用于连接所述原壳体111a、111b的壳体螺栓，以及用于连接所述盘式电机120a、120b的电机螺栓，同样地，所述安装孔133a、133b可分为所述壳体螺栓穿过的第一安装孔133a，以及所述电机螺栓穿过的第二安装孔133b，所述第一安装孔133a位于所述抵接面部1312，且多个所述第一安装孔133a以靠近所述接口部1311的方式，环绕于所述接口部1311的周围。多个所述第二安装孔133b以靠近所述连接盘130外周的方式，且圆周间隔排列。
在所述步骤(b2)中，当所述连接盘130利用所述结构连接面131连接于所述原壳体111a、111b后，将所述壳体螺栓穿过所述第一安装孔133a，并螺接于所述原壳体111a、111b，以拉结所述连接盘130和所述原壳体111a、111b。所述原壳体111a、111b和所述结构连接面131之间的连接方式包括但不限于：螺纹连接、套接、卡接或花键连接等。
在所述步骤(b3)中，当所述盘式电机120a、120b固定至所述电机连接面132后，将电机螺栓穿过所述盘式电机120a、122b，直至螺接于所述第二安装孔133b内，以拉结所述盘式电机120a、122b和所述连接盘130的连接。
所述第一安装孔133a可以为沉孔，这样所述壳体螺栓可从所述电机连接面132至所述结构连接面131方向插入至所述第一安装孔133a内，来拉结所述连接盘130和所述原壳体111a、111b，并且所述壳体螺栓隐藏于所述第一安装孔133a内，避免所述壳体螺栓外凸而影响所述盘式电机120a、122b和所述电机连接面132的贴合度。
如图1所示，所述盘式电机120a、122b包括电机壳体121a、121b和法兰盘122a、122b，所述法兰盘122a、122b设置于所述电机壳体121a、121b连接所述原壳体111a、111b的端面上。所述盘式电机120a、122b利用所述法兰盘122a、122b连接所述连接盘130。
如图4和图5所示，所述结构连接面131具有接口部1311和抵接面部1312，进而所述步骤(b2)包括：
将所述原壳体111a、111b螺接于所述接口部1311内，并贴合于所述抵接面部1312上。
所述接口部1311位于所述结构连接面131的中心，所述抵接面部1312呈大致环形，且围绕于所述接口部1311周围，当所述原壳体111a、111b对应连接于所述结构连接面131上时，将所述连接盘130的接口部1311螺纹连接于所述原壳体111a、111b上，直至所述抵接面部1312和所述原壳体111a、111b贴合。其中所述抵接面部1312上凹陷形成若干个凹槽13121，可用于减轻所述连接盘130的重量，并且所述连接盘130轴向尺寸小，这样避免所述连接盘130的重量影响所述原壳体111a、111b对所述盘式电机120a、122b的支撑能力。
如图4和图5所示，所述电机连接面132具有止口部1321和承接面部1322，所述盘式电机120a、120b包括法兰盘122a、122b，进而所述步骤(b3)包括：
将所述法兰盘122a、122b嵌入于所述止口部1321内，并贴合于所述承接面部1322上。
所述止口部1321位于所述电机连接面132中心，所述承接面部1322呈大致环形，且围绕于所述止口部1321周围，当所述盘式电机120a、120b对应连接于所述电机连接面132上时，先将所述盘式电机120a、122b上的法兰盘122a、122b嵌入于所述止口部1321内，直至贴合所述承接面部1322。
综上所述，所述搅拌车的搅拌上装200、能量回收系统300和所述空调系统400均可采用上述改造方法进行改造，即在原驱动设备的基础上，利用所述盘式电机取代油驱动，并且所述空调系统400可采用电驱动，能够较大程度的节约油耗。并且因盘式电机轴向尺寸小，重量轻等特点，无需额外增设支撑，降低成本，并且降低原驱动设备壳体对电机的负载，延长使用寿命。另外在盘式电机取代油驱动的改造过程中，能够直接利用原驱动设备上的原连接端112a进行连接，无需增设额外结构，使得改造过程更加简便，而且同时降低改造成本，更适合用于市场上现有燃油搅拌车的电驱改造。
