For a good car, a reliable braking device is essential. Manual braking devices have a history of centuries. /kloc-In the middle and late 20th century, people invented various dynamic braking devices, such as steam and air pneumatic braking devices, vacuum braking devices and hydraulic braking devices, which were used in trains and other vehicles.
Early cars generally used belt brakes or hoof brakes, and the brakes were all on the rear wheels of the car, which were mechanically connected to the joystick or pedal. 1904, Renouf obtained the patent right of front wheel brake. This brake was improved in Allen two years later, and 1909 was installed on aqel cars.
After Ford put forward various interchangeable separate brake linings in 1900, various brake linings that can match steel brake wheels or cast iron brake wheels appeared soon. 1902, Renault invented the standard brake wheel, which has two articulated brake shoes and a cam to separate the two brake shoes.
Since 19 19, Dewander et al. have obtained a series of patents on hydraulic auxiliary servo braking. In 1920, in order to make braking safer and more stable, Bendiks and others used double servo brakes in automobile braking devices. 1906 Dalac brakes have the same characteristics as contemporary brakes, and they are all made into various discs.
In the later braking device, in order to increase its sensitivity and reliability, new technologies such as electronic sensing were adopted. This can ensure that the brakes can stop the fast-moving car in a very short moment.
