Disk drum one-piece brakes and its working method
Technical field
The present invention relates to discharge plate drum one-piece brakes and its working methods.
Background technique
Braking system is an important system component of automobile, plays restrictive function to the running movement of automobile, performance it is good
The bad safety for directly affecting automobile.Braking is related to traffic safety, and great accident is often too long with braking distance, promptly
Situations such as breakking away when braking is related, thus when the braking of automobile vehicle safety travel important leverage, improve the system of automobile
Dynamic property is the vital task of Automobile Design manufacture and use department always.
Currently, friction brake used in all kinds of automobiles can be divided into drum-type and disc type two major classes.The former rubs the rotation in pair
Turning element is brake drum, and working surface is cylindrical surface;The rotating element of the latter is then discoid brake disc, using end face as work
Make surface.Rotating element is packed on wheel or semiaxis, i.e., braking moment is respectively acting on the brake on the wheel of two sides, referred to as
Wheel drag.Drum brake is at low cost easy to maintenance, but insensitivity is poor.Disk brake is also known as dish-style braking
Device, it is this brake rapid heat dissipation, light-weight, easy to adjust.Especially high load when high temperature resistance it is good, braking effect it is stable and
And more easily vehicle is enabled to stop in a relatively short period of time than drum brake with severe road conditions down train disc type brake in winter.But disc type
The brake disadvantage low there is also brake efficiency.
