【摘要】 依据摆锤式冲击试验台的结构与工况要求,设计了一种新型牙嵌式液压离合器。该离合器利用接合弹簧力及分布式固定柱塞缸所产生的液压力实现左、右半离合片端面齿的接合与分离。基于所设计的牙嵌式液压离合器的结构参数,采用ADAMS仿真软件,建立了牙嵌式液压离合器的仿真模型,并对其进行了仿真分析。仿真结果表明,液压离合器在接合弹簧力的作用下能有效传递负载扭矩,且接合迅速,接合时间仅为0.019 s;当各柱塞缸的工作压力不低于7.3 MPa时,液压离合器能快速分离,分离时间不大于0.012 s。所设计的液压离合器在摆锤式冲击试验台上已运行考核两年。考核结果表明,该液压离合器具有工作压力高、离合平稳、结构紧凑、转动惯量小及安全可靠等优点,能够满足摆锤式冲击试验台的结构与使用工况要求。更多还原

【Abstract】 According to the structure and working condition requirements of pendulum impact test bench, a new jaw hydraulic clutch is designed. Relying on engagement spring force and the hydraulic pressure generated by the distributed fixed plunger cylinder, the clutch can achieve the engagement and separation of the end face teeth of the left and right half clutch plates. Based on the structural parameters of the designed jaw hydraulic clutch, by using ADAMS simulation software, model of the jaw hydraulic clutch is established, and the simulation analysis is carried out. According to simulation results, the hydraulic clutch can effectively transmit the load torque under the action of the engagement spring force, and the engagement is rapid and done in 0.019 s; when the working pressure of each plunger cylinder is not lower than 7.3 MPa, the hydraulic clutch can be quickly separated for not more than 0.012 s. The designed hydraulic clutch has been tested on pendulum impact test bench for two years. The examination results show that the hydraulic clutch has the advantages of high working pressure, stable clutch, compact structure, small moment of inertia, being safe and reliable, and can meet the requirements of the pendulum impact test bench structure and operating conditions.更多还原
