检测试验台; 研制; 应用1 引言随着社会经济的飞速发展 ,液力传动变速箱逐渐取代了机械式传动的普通变速箱。据调查，美国Allison 等液力传动变速箱市场用量很大 ,但其价格昂贵、结构复杂、修理技术含量高、故障判断难度大 ,而且还需要检测试验台带动运转 ,检测液力传动变速箱的油压、转速、温度等 ,录取各种技术参数 ,判断排除故障。而要购买一台检测设备需要投资200 多万元。为了经济有效地提高液力传动变速箱修理速度和质量 ,开拓大西北的修理市场 ,长庆石油勘探局第三采油技术服务处机械维修站自行设计制造了ZF 、Allison 液力传动变速箱检测试验台等工装设备 ,并投入了液力传动变速箱修理使用中;开发了德国ZF 、美国Allison 液力传动变速箱修理工艺技术 ,成功修理了ZF 、Allison 变速箱 ,带负荷检测试验后安装到修井机上投入了修井使用。美国Allison 液力传动变速箱检测试验台的研制 , 使修理后的液力传动变速箱能够通过检测试验台带负荷检测试验 ,录取技术参数、判断排除故障,分析应用效果等。要求研制的液力传动变速箱检测试验台及时准确地反映被检测液力传动变速箱的各项技术参数 , 包括检测录取各种挡位油压、润滑油压、转速、扭力、温度等技术参数 ,判断排除异响、泄露离合器、制动器、离合器打滑、回位不及时等故障。为了使液力传动变速箱检测试验台设计合理 ,确保大修检测试验后的液力传动变速箱工作平稳、性能稳定、安全可靠 ,我们首先研究了液力传动变速箱的结构、性能及工作原理。2 变速箱结构及工作原理美国Allison 变速箱主要由变矩器、闭锁离合器、行星齿轮和离合器、液力变速器组成。（1）变矩器: 由泵轮、涡轮、导轮组成一个循环圆系统 ,液体顺序通过循环流动。泵轮由发动机驱动 ,是动力输入元件。涡轮由泵轮经过液力传动 ,是动力输出元件。导轮的作用是导流 ,增大扭矩。变速器的供油泵不断向变矩器供油,使变矩器工作 ,增加发动机的输出扭矩。通过变矩器排出的油带走变矩器的热量。液体由泵轮流入涡轮改变方向。导轮将从涡轮流出的油经油道改变方向后再流入泵轮 ,因此导轮受一反作用扭矩。涡轮与泵轮扭矩比为变矩比,随涡轮与泵轮的转速比降低而增大 ,随输出转速的提高,变矩比降低。通过变矩器 ,输出转速可无级变化 ,驱动扭矩自动适应所需的负载扭矩。当涡轮转速达到泵轮转速的涡轮扭矩等于泵轮扭矩 ,此时变矩器相当于一个偶合器。 当车速升高,变矩比接近 1 ,且牵引力不再增大时,闭锁离合器就自动闭锁。（2）闭锁离合器（CT型和CBT型除外）:当涡轮升高到一定转速时,液压力自动把泵轮和涡轮锁住。在闭锁离合器的作用下 ,变速箱输入轴的转速和发动机相同。（3）行星齿轮和离合器：四组行星排齿轮产生五个前进档和一个倒档。行星齿轮通过六个液压接合的离合器操纵。全部齿轮为常啮合式。（4）液力变速器:CBT和CLBT754 型的变速箱装有液力变速器。液力变速器上有一个带叶片的转子和两个带叶片的定子组成。(5) 挡位和接合离合器:空挡:1档离合器、2档离合器。前进档:1档和 1档离合器、2 档和 2档离合器、3档和 3 档离合器、4 档和4档离合器、5档和5档离合器。倒档:5 档和 1 档离合器、5 档和2 档离合器。3.液力传动变速箱性能特点在同等工况下 ,与普通变速箱相比,使用液力传动变速箱可节油5 %22 % 。而且操作简单 ,使用方便 , 性能可靠。对提高发动机以及传动系统的使用寿命、发动机的动力性、经济性和车辆设备的安全性能效果十分显著。美国Allison 液力传动变速箱是一种位于动力机与工作机之间的以液体为工作介质的流体传动机械 ,并根据负载功率的变化来实现变
