重卡变速器中大扭矩定扭反力问题的研究和应用

The Application Research on the Counter-Force of Fixed Torque about Heavy Truck Transmission

文章通过对法兰盘凸缘螺母处机械结构进行分析,对电动定扭设备拧紧原理进行深入研究,对法兰盘凸缘螺母在定扭拧紧时的受力情况建立力学模型,得到了重型商用车变速器法兰盘定扭拧紧时的受力情况,从而给出最为经济和稳定的抗反方案,为以后法兰盘定扭推广打下了理论基础,并给出了法兰盘凸缘螺母定扭拧紧时的反力装置模型,简化了法兰盘定扭拧紧的反力装置结构,并降低了法兰盘定扭方案的难度和成本。

The article shows the most economical and stable anti-Counter-Force solution on the basis of analysis about the flange mechanism,the study of fixed equipment and building the force modle.then,the paper shows the ant- Counter- Force solution modle which solution can reduces the cost and mechanism.
