Form and development trend of modern automobile brake
Brake control the original driver just a set of simple mechanical device applying force to the brake, when the vehicle quality is relatively small, relatively low speed, mechanical brake has to meet the needs of vehicle braking, but with the increase of automobile self quality, boosting device of mechanical brake, it is necessary to
. The DuesenbergEight took the lead in using the car hydraulic brake. Chrysler's four wheel hydraulic brake came out in 1924. General motors and Ford adopted hydraulic brake technology in 1934 and 1939 respectively. By 1950s, hydraulic brakes had become a reality.
With the development of science and technology and the development of automobile industry, especially the development of military vehicles and military technology, new breakthroughs have been made in vehicle braking, and hydraulic braking is another important innovation after mechanical braking
At this point, a vacuum assist device began to appear. The quality of production in 1932 2860kg Cadillac V16 car four wheel drum brake using 419.1mm diameter, and vacuum booster brake pedal control. The Lincoln Company also launched the V12 sedan in 1932, using a drum brake operated by four soft cords to control the vacuum booster.
