Description

Technical Field

[0001] The utility model relates to the technical field of brake steel backs, in particular to a brake steel back with concave nails. Background Art

[0002] The automobile braking system refers to a series of specialized devices that apply a certain force to certain parts of the automobile (mainly the wheels) to force braking to a certain extent. The functions of the braking system are: to force the moving car to slow down or even stop according to the driver's requirements; to keep the stopped car stable under various road conditions (including on ramps); and to keep the speed of the car driving downhill stable.

[0003] For example, the authorization announcement number "CN213511801U" is named as an improved structure of the brake pad steel back. Although the setting of a number of countersunk holes reduces the material usage while improving the heat dissipation effect of the steel back and prolonging the service life, the setting of a number of countersunk holes will reduce the strength of the overall steel back; usually, after the friction material is worn flat, the brake device can only be replaced as a whole, and the brake steel back cannot be used again.
