Description
Technical field
The present invention relates to art of braking devices, especially a kind of fast insert wears alarm mechanism and its assembly method.
Background technique
Drum brake is the arrestment mechanism that automobile chassis braking system is applied earliest, as automobile industry continues to develop,
Corresponding regulation is put into effect successively, is required to be continuously improved to existing drum brake, is not required nothing more than it and meet braking ability, it is also necessary to
Have other intelligent miscellaneous functions；The requirement mentioned in new standard GB/T7258 is " when running brake brake lining needs replacing
When, the warning device of Ying Caiyong optics or acoustics is alarmed to the driver on driver's seat ", specify the structure of drum brake
It is middle to include the requirement of the warning device for brake pad wear alarm.
In the prior art, occurred the wear abrasion alarming device for drum brake of various structures successively in the market,
The breakaway-element wear abrasion alarming device of disk brake batch application is mainly used for reference on mechanism principle；Such alarm mechanism application
Although can be realized warning function on drum brake, due in drum-type and disk brake overall construction itself exist compared with
Big difference, the increase of alarm mechanism result in the increase of many new techniques and process on drum brake, and side effect is very big.
Automobile industry especially commercial vehicle industrial profit space is minimum, and the increase of alarm mechanism is bound to cause the increasing of cost
Add, and alarm mechanism belongs to expendable part, the controllability of replacement cost and replacement after abrasion must pay attention to；In addition, by
The installation space of the influence of this body structure of drum brake and working condition, alarm mechanism is limited and the complexity of its working environment,
It must antidetonation and high temperature resistant.
