针对某6×4重型牵引车的开发,进行动力匹配设计。通过多轮仿真分析及优化整车附件降低风阻。应用分轮位花纹轮胎匹配技术,同时优化轮胎结构和材料,使开发车的轮胎滚阻系数降低。改变变速箱及后桥齿轮和轴承结构,降低润滑油阻力,提高传动效率。通过动力总成和后桥速比合理匹配及优化发动机风扇性能,使发动机万有特性适合整车在一定工况下的运行区域。从而使整车具备优越的动力性和经济性,并结合CRUISE软件的仿真分析,最终实现整车性能达到预期目标。
For a 6 × 4 heavy tractor development, power matching design. Through multiple rounds of simulation analysis and optimization of vehicle accessories to reduce wind resistance. The application of tire wheel tread pattern matching technology, while optimizing the tire structure and materials, so that the development of the vehicle tire rolling resistance reduction. Change the gearbox and rear axle gear and bearing structure to reduce the oil resistance and improve the transmission efficiency. Through the powertrain and rear axle rationally match and optimize the engine fan performance, make the engine universal characteristics suitable for the vehicle under certain operating conditions of the operating area. So that the vehicle has superior power and economy, combined with CRUISE software simulation analysis, and ultimately achieve the desired vehicle performance.
