Abstract

Article pays attention to the impact of using the trailer on driving performances of a studied vehicle combination.The research was performed via extensive experimental measurements. A new methodology of determining a technical condition of the trailer' brakes was proposed and verified, which can be also applied during the regular technical inspection. Various load distributions in the trailer caused the centre of gravity's position of the vehicle was changed, which may increase the risk of skidding or disconnection of the trailer from the towing vehicle. Also, the vehicle's ability to accelerate and decelerate decreased considerably due to the loading up. There were assessed the braking characteristics of the combination of vehicles as well, depending on the technical condition of the trailer's brakes. The importance of this article lies in the quantification of selected factors on road safety in relation to driving with a combination of vehicles.

摘要

文章关注使用挂车对所研究的车辆组合驾驶性能的影响。该研究通过广泛的实验测量进行。提出并验证了一种确定挂车制动技术状况的新方法，该方法也可应用于定期技术检查。挂车中各种载荷分布导致车辆重心位置发生变化，这可能增加挂车打滑或与牵引车分离的风险。此外，由于装载，车辆的加速和减速能力大幅下降。还根据挂车制动器的技术状况评估了车辆组合的制动特性。本文的重要性在于量化与车辆组合驾驶相关的道路安全选定因素。
