Abstract: Maneuverability is one of the important performance indicators of the off-road vehicle, with the development of automatic transmisson technology, Chinese independent off-road vehicles match automatic transmisson, obvious technical advantages, the dynamic performance is effectively improved. Through simulation analysis, dynamic calculation, and vehicle test, ensure the excellent performance of the vehicle. The research and analysis results lay the foundation for a large number of matching applications of automatic transmisson in the off-road vehicle.

Key words: Off-road vehicle; Hydraulic automatic transmission; Dynamic performance

摘要： 机动性是越野汽车的重要性能指标之一，随着国产液力自动变速箱技术的发展，我国 自主越野汽车陆续匹配液力自动变速箱，技术优势明显，有效提高了整车动力性。文章通过 仿真分析，对某款匹配液力自动变速箱的越野汽车动力性进行了计算，并经试验验证，确保 了该款车的优良性能。通过该研究分析成果，为液力自动变速箱在越野汽车上大量匹配应用 打下了基础。
