The paper deals with the design of a system for changing the adhesion conditions in a road vehicle. The change in adhesive force is done by changing the radial reaction which the vehicle wheel transmits to the road. The paper describes a new device (SkidSystem) and its construction. The main element of the device is done in the form of a supporting frame; four supporting wheels are attached to this frame. As a result of the mechanical change of wheel lift, the radial reaction is reduced. Subsequently, an experimental measurement is performed, where the waveforms of basic physical quantities describing the road vehicle behaviour are measured. Driving in a straight line with the so-called panic braking was selected as an experimental test. An experimental vehicle is used to carry out the experimental measurement. According to the results found, modifications of the device are proposed, so that the results were closer to testing under real conditions. Disadvantages of SlidingFrame were the increase in the car weight, a slight change in the car centre of gravity and a limited angle of inclination of the body during intensive braking.

改变实验道路车辆附着条件的系统

该论文涉及用于改变道路车辆附着条件的系统的设计。附着力的变化是通过改变车轮传递到路面的径向反作用力来实现的。该论文描述了一种新设备(SkidSystem)及其结构。该设备的主要元件以支撑框架的形式完成;四个支撑轮连接到这个框架上。由于车轮升程的机械变化,径向反作用力减小。随后,进行实验测量,测量描述道路车辆行为的基本物理量的波形。选择了所谓的紧急制动直线行驶作为实验测试。实验车辆用于进行实验测量。根据发现的结果,建议对设备进行修改,以便结果更接近真实条件下的测试。SlidingFrame的缺点是车重增加,车重心略有变化,强烈制动时车身倾斜角度有限。
