The utility model proposes a kind of shoe brakes, please refer to Fig. 1 and Fig. 2, including 1 He of the tendons of beef, mutton or pork connected by backboard 2
Friction plate 3, backboard 2 are located at the outside of the tendons of beef, mutton or pork 1, and friction plate 3 is fixed on backboard 2, are equipped on the outside of the tendons of beef, mutton or pork 1 towards 3 side of friction plate
To the protrusion 11 of extension, the top of protrusion 11 is higher than the outer end face of backboard 2, and is lower than the outer end face of friction plate 3.
In the present embodiment, the shape of protrusion 11 is rectangle, can also be ellipse, three certainly in other embodiments
Angular or other polyhedral shapes, are not specifically limited herein.
The height of protrusion 11 is determined according to concrete technology demand, for example, backboard is exposed on the top of protrusion 11 in the present embodiment
2 distance is 1.6mm, when friction plate 3 is gradually worn out, is flushed until friction plate 3 is worn down to the raised 11 structure ends of the tendons of beef, mutton or pork 1
When (3 limit of wear position of friction plate), if being further continued for wearing, the raised 11 structure ends of the tendons of beef, mutton or pork 1 will form dry with brake drum working face
Friction generates noise, that is, has reminded driver to need to replace shoe brake or safeguard, prevented because of brake shoe plate abrasion
It fails and influences braking effect, reduce accident rate.The alarm structure of the utility model simply easily realizes that manufacturing cost is low.
Specifically, protrusion 11 is integrally formed with the tendons of beef, mutton or pork 1, and backboard 2 is equipped with the through-hole for wearing protrusion 11.It is integrally formed
Structure make the overall structure of shoe brake simpler, it is easy to install, increase the stable fastness of shoe brake.When installation hoof
When muscle 1 and backboard 2, the protrusion 11 of the tendons of beef, mutton or pork 1 is passed through to the through-hole of backboard 2, the structure of the size and protrusion 11 of through-hole does well to coincide,
Further increase the stability of structure.
As an implementation, it is symmetrically arranged with two protrusions 11 on the tendons of beef, mutton or pork 1, and bears against at the both ends of friction plate 3.
The effect that above structure not only has automatic alarm friction plate 3 to need to change, and protrusion 11 can also play the work for blocking friction plate 3
With increasing the stability of entire shoe brake structure.Certainly, it should be noted that in other embodiments, of protrusion 11
Number or 1,3 or be greater than 3；The position of protrusion 11 is also not necessarily limited to be resisted against the both ends of friction plate 3, can also be with
Friction plate 3 maintains a certain distance, as long as can achieve the effect that the automatic alarm when friction plate 3 is worn to a certain extent,
Therefore, the specific number at this to protrusion 11 and position are not made specifically defined.
Specifically, outside of the protrusion 11 perpendicular to the tendons of beef, mutton or pork 1.It will be set as vertical structure between protrusion 11 and the tendons of beef, mutton or pork 1, can mentioned
The utilization rate of high protrusion 11, saves manufacturing cost.
More specifically, the tendons of beef, mutton or pork 1, backboard 2 and friction plate 3 are in semi-moon shaped shape, wherein the width of friction plate 3 is less than backboard
2 it is wide, increase fastness and stability between friction plate 3 and backboard 2.
In the present embodiment, backboard 2 and 1 rivet or weld of the tendons of beef, mutton or pork.Friction plate 3 is bonded together with backboard 2 by viscose glue,
And friction plate 3 is bonded between two parties on backboard 2.Friction plate 3 can be bonded together with backboard 2 by the viscose glue that glue spreader is smeared,
It is dried using high temperature；Can also be bonded together by spaced striped viscose glue, at the same the side edge of friction plate 3 there are
Several millimeters of non-gluings, it is therefore intended that guarantee to fill when bonding agent flowing to the outer edge of friction plate 3, but do not overflow
The outer edge of shoe brake.
Abrasion resistant particles are also distributed on 3 outer end face of friction plate in the present embodiment, increases coefficient of friction, improves braking
The intensity of shoe plate.
In addition, the utility model additionally provides a kind of drum brake, including brake drum and above-mentioned shoe brake, brake-shoe
Braking surface of the friction plate 3 of piece facing to brake drum.
In addition, the utility model additionally provides a kind of vehicle, including wheel and with above-mentioned drum brake.Above-mentioned vehicle tool
There is brake shoe plate abrasion alarm structure, shoe brake is replaced or safeguarded by sound prompting driver, prevents because of system
It moves shoe plate wear-out failure and influences braking effect, reduce accident rate.
The above is only the preferred embodiment of the present invention, and therefore it does not limit the scope of the patent of the utility model,
It is all under the design of the utility model, equivalent structure transformation made based on the specification and figures of the utility model, or
Directly/be used in other related technical areas indirectly and be included in the scope of patent protection of the utility model.
