<p>The invention provides an aerodynamic auxiliary braking apparatus for motor vehicle. Roof of the vehicle is a main air resistance plate. The plate is hinged to a corresponding part of vehicle body. A late lock comprises a upper body provided on the plate and a lower body provided at the vehicle body. A pulling switch of the late lock composed of a cable is connected with an arm of brake pedal of the vehicle. A control device includes guide wheels fixed to the vehicle body and reels around which cables is wound. The present invention decreases the braking distance of motor vehicle significantly by means of an large air resistance of the main air resistance plate, and improves safety of the vehicle. Restrict to increase vehicle speed is eliminated due to the significantly shortened braking distance.</p> |
