The invention relates to a cross-country escape auxiliary wheel. The cross-country escape auxiliary wheel comprises an auxiliary wheel mechanism; the auxiliary wheel mechanism is installed on one sideof a brake disc through a fixing screw; the auxiliary wheel mechanism comprises an installation combination part; the installation combination part is connected with a ground contact part through a vertical supporting part; a screw hole matched with the fixing screw in specification is drilled in the installation combination part; the main body of the vertical supporting part is a spring steel wheel disc; and rubber for tires is additionally arranged on the ground contact part. Compared with the prior art, the wheel has very high adaptability and practicability when used for preventing vehicles from being trapped in sandy land and muddy land; when a tire of a vehicle bursts and the vehicle sinks, the auxiliary wheel can automatically contact with the ground to replace the tire to work toprevent the vehicle from being out of control suddenly; a plurality of auxiliary wheels can be overlapped to facilitate storage; by means of the characteristic that lengthened screws and the auxiliarywheels can be installed in a stacked mode to reduce elastic deformation, the maximum outer diameter is expanded, a spare tire is replaced for emergency use, and therefore cross-country adaptability,practicability, safety and convenience are greatly improved.
本发明公开了一种越野脱困副轮,包括副轮机构,副轮机构通过固定螺丝安装在刹车盘一侧,副轮机构包括安装结合部,安装结合部通过竖直支撑部连接有地面接触部;安装结合部上钻设有与固定螺丝规格相适配的螺丝孔;竖直支撑部主体为弹簧钢轮盘;地面接触部上加装有轮胎用橡胶。本发明与现有技术相比的优点在于:在沙地、泥泞地防止陷车具有很强的适应性和实用性;车辆爆胎、下陷时副轮会自动接触地面,替代轮胎工作防止车辆突然失控;多个副轮可以重叠方便存放;利用加长螺丝、副轮可叠加安装以减轻弹性变形的特点,撑大最大外径,替代备胎应急使用,从而大大提高了越野的适应性、实用性、安全性和便利性。
