The invention provides automobile side surface protection devices utilizing cylindrical rollers or spherical rollers. The automobile side surface protection devices utilizing the cylindrical rollers or the spherical rollers comprise rectangular frames at least installed at the position of an original side surface protection assembly, vertical cylinders transversely arranged on the frames and the cylindrical rollers or the spherical rollers assembled on each vertical cylinder in a stringing mode, and the cylindrical rollers or the spherical rollers are in movable fit with the vertical cylinders. According to the further improvement, the protection devices composed of the rectangular frames, the vertical cylinders transversely arranged on the frames and the cylindrical rollers or the spherical rollers assembled on each vertical cylinder in a stirring mode are additionally arranged on the outer side of a rear wheel, the two ends of an automobile front bumper and the outer side of an adjacent automobile body. The automobile side surface protection devices utilizing the cylindrical rollers or the spherical rollers have the positive effect that the friction force, the impact force and the moment of force between a small automobile colliding with a truck and a large automobile are reduced. When an expressway guardrail is scratched, the inertia force of the automobile is resolved, theprobability of automobile rollover and carriage tearing is reduced, and the damage degree to the expressway guardrail is reduced.
一种利用柱形滚或球形滚的汽车侧面防护装置,包括:至少安装在原侧面防护总成位置的矩形框架,框架上横向排列的竖向圆柱,成串装配在每根竖向圆柱上的多个柱形滚或球形滚,柱形滚或球形滚与竖向圆柱动配合。其进一步改进是:由矩形框架,框架上横向排列的竖向圆柱,成串装配在每根竖向圆柱上的多个柱形滚或球形滚组成的防护装置增设在后车轮外侧、车前保险杠两端及相邻的车体外侧。本发明的积极效果是降低与货车相碰撞的小型汽车与大型车的摩擦力、冲击力和力矩。在高速公路护栏发生刮碰时,化解车本身的惯性力,降低车辆侧翻和车厢撕裂的几率。降低对高速公路护栏的破坏程度。
