摘　　要：为了研究离合器液压分离轴承缸体结构对密封圈压入力的影响,建立了液压分离轴承有限元模型,对液压分离轴承密封圈压入过程进行了分析,得到了密封圈压入力随位移变化的关系曲线,并与相关试验结果进行对比分析,验证了有限元模型的正确性。利用建立的模型,分析了轴承缸体结构参数以及与密封圈摩擦因数对压入力的影响。结果表明,在刚被压入时,密封圈受到的压入力波动较大,随后逐渐减小并趋于稳定。降低摩擦因数,增大缸体的内径和降低缸体外径可以有效地降低密封圈受到的压入力。该建模方法和结论对液压分离轴承的设计和结构优化具有一定的指导意义。The finite element model of Hydraulic release bearing is established to study the influence of the construction of clutch hydraulic release bearing cylinder on the pressing force of sealing ring,and this model is used for analyzing the process of pressing into the hydraulic release bearing＇s sealing ring.The characteristic curve of the pressing force of sealing ring and the displacement is obtained.The model is validated by comparing the calculated and experimental result.Then using the established model,the influence of the bearing cylinder＇s construction and the sealing ring friction coefficient for the pressing force of seal ring is analyzed.The results show that the pressing force of sealing ring has a big fluctuation when it is just pressed,then gradually reduces and tends to be stable.If the friction coefficient and the outer diameter of cylinder reduce or the inner diameter of cylinder increases,the pressing force of sealing ring would reduce effectively.The developed model and conclusions proposed are instructive for the design and structure optimization of clutch hydraulic release bearing.
