VEHICLE BRAKE DEVICE USING GRAVITY ACCELERATION FOR RAPIDLY STOPPING A VEHICLE UNDER TRAVELING

摘要

PURPOSE: A vehicle brake device using gravity acceleration is provided to secure the stoppage of a traveling vehicle by increasing the friction between a brake lever and the road surface using the gravity acceleration proportional to the speed of the traveling vehicle. CONSTITUTION: A vehicle brake device using gravity acceleration comprises a brake lever driver(2), a brake lever backward gear(3), a brake lever support frame(4), a brake lever(5), a brake lever fixing pin(6), and a brake lever protector(7). The brake lever backward gear turns backward while holding the brake lever, and the brake lever is placed under vehicle wheels. According to the weight of a vehicle, the rubber of the vehicle wheels frictionally contacts the brake lever. Gravity acceleration is generated by speed of the traveling vehicle. Thus, the friction between the brake lever and the road surface is increased.
