摘要
从安全性和经济性两个方面对长下坡工况下液力缓速器对整车的贡献进行了研究。研究表明:液力缓速器可以大幅提高重型商用车下坡安全性,降低车辆运营成本,提高运营效率,保障重型商用车安全、经济、高效地运行,具有极大的社会效益和经济效益。
The contribution of hydraulic retarder to the whole vehicle under long downhill conditions was studied from two aspects of safety and economy.Research shows that the hydraulic retarder can greatly improve the safety of heavy commercial vehicles downhill,reduce vehicle operating costs,improve operational efficiency,and ensure safe,economical and efficient operation of heavy commercial vehicles,with high social and economic benefits.
