摘要
文章针对重型汽车在长大下坡路段的行驶安全问题,对辅助减速车道的设计进行研究。根据排气制动和液力缓速器联合制动的行驶模型,对重型车辆在长大下坡路段的下坡能力进行研究。根据下坡时制动器的温升模型,研究长大下坡路段的辅助减速车道位置设计问题。
This paper studies the design of auxiliary deceleration lanes for the safety of heavy vehicles on the downhill section.According to the driving model of exhaust brake and hydraulic retarder combined braking,the downhill capacity of heavy vehicles on the downhill section is studied.According to the temperature rise model of brake in downhill,the position design of auxiliary deceleration lane in long downhill section is studied.
