PURPOSE: A snow brake is provided to minimize a slip of a traveling vehicle and reduce a braking distance by contacting a road with a separate brake except a wheel. CONSTITUTION: A brake switch(1) is operated when a driver finds a dangerous slip on a freezing road. A snow brake(5) is pushed by an operation of a motor because pressure of a hydraulic tank is transferred to a piston(4) through a hose. Thereby, a vehicle brakes because the snow brake frictionizes the road. Power of the piston is adjusted by the operation of the switch. The snow brake is produced in a folding type for convenient traveling and simplicity of a device. Thereby, a slip of the vehicle is minimized and a braking distance is reduced by preventing the slip with the snow brake contacted to the road directly. |
