摘　　要：驻车机构作为汽车变速器中的重要安全组件,其设计直接影响整车的驻车性能与安全性。为精确有效验证驻车机构的临界驻车速度及其他因素对驻车效率的影响,采用Adams软件对某驻车机构进行了多体动力学仿真分析。研究表明,该机构能够在车辆车速接近2.5 km/h时实现安全、稳定的驻停。通过进一步的仿真研究,探讨了推杆弹簧刚度和预载荷对驻车性能的影响。结果显示,适当增大弹簧刚度或预载荷可有效缩短驻车时间,提高驻车效率。As a crucial safety component in automotive transmissions,the design of the parking mechanism directly influences the vehicle's parking performance and safety.To precisely and effectively verify the critical parking speed of the parking mechanism and the impact of other factors on parking efficiency,this paper employs Adams software to conduct a multi-body dynamic simulation analysis of a specific parking mechanism.The study reveals that the mechanism can achieve safe and stable parking when the vehicle speed is approximately 2.5 km/h.Through further simulation research,the effects of push rod spring stiffness and preload on parking performance were investigated.The results indicate that appropriately increasing the spring stiffness or preload can effectively shorten the parking time and improve parking efficiency.The findings of this study provide a basis for parameter optimization in the design of parking mechanisms and performance enhancement under actual working conditions.
