The utility model discloses an anti-rollover protection device for automobiles. The utility model comprises a supporting wheel, a driving cylinder and a telescopic arm arranged under the automobile chassis. The cylinder block of the driving cylinder is fixed on the automobile chassis, the piston rod of the driving cylinder is obliquely downward, the upper end of the telescopic arm rotates on the automobile chassis, and the supporting wheel is arranged on the lower end of the telescopic wall to drive the cylinder to live. The plug rod is rotated and connected with the lower end of the telescopic arm, and the axis of the driving cylinder and the telescopic arm are in an inclined plane which inclines downward from the middle of the chassis to the side of the automobile. The utility model controls the support wheel to retract under the automobile chassis and extend out the automobile chassis by driving the oil cylinder, and the height of the support wheel decreases while extending, so that the support wheel does not hinder the driving of the automobile wheels when retracting under the automobile chassis, and has better anti-rollover effect when extending. The utility model has compact structure, saves space and is convenient for installation on automobiles.

一种汽车防侧翻保护装置
本技术涉及汽车制造
,具体为一种汽车防侧翻保护装置。
技术介绍
在雨雪天气中行车容易发生侧翻,防止汽车发生侧翻是提高行车安全的重要途径,例如申请号为CN98236213.7的技术专利包括对称安置在汽车底盘两侧的伸缩式侧翻架,所述侧翻架是由至少两节套管组成的伸缩式支杆和固结在伸缩式支杆前端的触地式侧翻杆组成,在伸缩式支杆的腔体内安置有弹性件,在触地式侧翻杆的一端开设有与汽车上设置的锁销相对应的回位锁定孔,所述的弹性件为弹簧,所述的伸缩式支杆一侧为两根,另一侧为三根,该技术虽然结构复杂,占用空间大,不便在汽车上安装。
技术实现思路
本技术的目的在于提供一种结构紧凑的汽车防侧翻保护装置。为实现上述目的,本技术包括支撑轮以及设置在汽车底盘下方的驱动油缸和伸缩臂,驱动油缸的缸体固定在汽车底盘上,驱动油缸的活塞杆斜向下,伸缩臂的上端转动设置在汽车底盘上,支撑轮设置在伸缩壁的下端上,驱动油缸的活塞杆与伸缩臂的下端转动连接,驱动油缸的轴线和伸缩臂的轴线处于一个从汽车底盘中部向汽车一侧向下倾斜的斜面内,驱动油缸的活塞杆的伸缩范围在前述的斜面内,伸缩臂的伸缩及转 ...
