Technical field
The present invention relates to a kind of braking system part, and in particular to a kind of brake-shoe structure in brakes.
Background technology
As shown in figure 1, existing drum brake system mainly includes brake drum 2, brake strip 3, system
Dynamic hoof 1`, brake shoe anchor bolt 4, brake-shoe drive pin 5, retainer spring 6 and brake camshaft 7.
Reaction force final supporting pin end 121 by brake-shoe 1` of the brake drum 2 to brake-shoe 1` during automobile brake
Undertake, therefore brake shoe anchor bolt end 11 is region of stress concentration.As shown in Fig. 2 brake-shoe 1` structures include
Brake-shoe mainboard 11 and brake-shoe web 12, one end of brake-shoe web 12 is supporting pin end 121, another
It is drive pin end 122 to hold, and the supporting pin end 121 is provided with the supporting pin half for installing brake shoe anchor bolt 4
Open tray 1211 and the spring eye 1212 for installing retainer spring 6.Existing brake-shoe 1 is in branch
The structure at support pin end 121 is thiner, and under long-term stress concentration environment, fatigue deformation easily occurs
And scrap, and drive pin end 122 also would tend to occur fatigue under the long-term driving effect of brake camshaft 7
Deformation.And, long-term immobilization can cause the spacing of brake-shoe web 12 to change, and cause malformation and shadow
Ring braking effect.Further, since existing brake-shoe mainboard 11 is single plank frame, its weight is big and scattered
Heat differential, braking effect cannot be lifted further.
The content of the invention
It is an object of the invention to regarding to the issue above not in part, there is provided a kind of reinforced punch welding braking
Hoof, its structural strength for improving supporting pin end and drive pin end, it is to avoid brake-shoe web spacing changes,
Improve the service life and braking effect of brake-shoe.
In order to achieve the above object, the present invention uses following technical scheme：
New reinforced punch welding brake-shoe, including brake-shoe mainboard and brake-shoe web, brake-shoe web
One end be supporting pin end, the other end be drive pin end, the supporting pin end is provided with for installing brake-shoe branch
Support the supporting pin half opening seat and the spring eye for installing retainer spring of pin, the brake-shoe web
A U-shaped reinforcement bridge plate is welded with the inside of supporting pin end, the U-shaped reinforcement bridge plate is welded on system including two
The reinforcement side plate at the supporting pin end of dynamic hoof web and be connected between two reinforcement side plates and strengthen bridge plate, described two plus
Strong side plate is respectively equipped with the reinforcement half opening seat matched with half opening seat and the reinforcement bullet matched with spring eye
Spring hole；The brake-shoe web is welded with a reinforcement pins on the inside of drive pin end.
Further, the two reinforcement side plate is integrated punch forming with bridge plate is strengthened.
The reinforcement bridge plate middle part is provided with arch bridge opening, and the effect of the arch bridge opening is can both to mitigate reinforcement bridge
The weight of plate, can strengthen reinforcement bridge plate to resistance to compression bending strength again.
Further, drive pin end both sides are stamped with reinforcement pins mounting hole, pacify on the reinforcement pins mounting hole
Fill reinforcement pins and by being welded and fixed.
In order to mitigate weight, the reinforcement pins are a hollow reinforcement pins.
In order to mitigate the weight of brake-shoe and improve radiating effect, the further lifting of braking effect, institute are realized
State and some through holes for mitigating weight and radiating are stamped with brake-shoe mainboard.
The present invention structural improvement innovatively is carried out to brake-shoe, supporting pin end set it is U-shaped reinforcement bridge plate and
Reinforcement pins are set in the inner side at drive pin end, the intensity of brake-shoe web is improved, it is to avoid brake-shoe web spacing
Change, improve the service life and braking effect of brake-shoe.

Fig. 2 is existing brake-shoe structural representation.
Fig. 3 is the Facad structure stereogram of brake-shoe of the present invention.
Fig. 4 is the front view of brake-shoe of the present invention.
Fig. 5 is the backside structure stereogram of brake-shoe of the present invention.
Below by way of the drawings and specific embodiments, the invention will be further described：
Specific embodiment
As shown in Fig. 3 to 5, new reinforced punch welding brake-shoe 1 of the present invention, including brake-shoe
Mainboard 11 and brake-shoe web 12, one end of brake-shoe web 12 is supporting pin end 121, and the other end is drive
Dynamic pin end 122, the supporting pin end 121 is provided with the supporting pin half opening seat for installing brake shoe anchor bolt 4
1211 and for installing the spring eye 1212 of retainer spring 6.
In order to increase the intensity at supporting pin end, the brake-shoe web 12 is welded in the inner side at supporting pin end 121
There is a U-shaped reinforcement bridge plate 13, the U-shaped bridge plate 13 of strengthening includes two branch for being welded on brake-shoe web 12
Support is sold the reinforcement side plate 131 at end 121 and is connected to reinforcement bridge plate 132, described two between two reinforcement side plates 131
Strengthen side plate 131 and be respectively equipped with the reinforcement half opening seat 1311 and and spring matched with half opening seat 1211
The reinforcement spring hole 1312 that hole 1212 matches.
Further, the two reinforcement side plate 131 is integrated punch forming with bridge plate 132 is strengthened.
The middle part of reinforcement bridge plate 132 is provided with arch bridge opening 1321, and the effect of the arch bridge opening 1321 is both may be used
Strengthen the weight of bridge plate 132 to mitigate, reinforcement bridge plate 132 can be strengthened again and arrives resistance to compression bending strength.
In order to strengthen the intensity at drive pin end 122, prevent brake-shoe web 12 from deforming, the brake-shoe web
12 are welded with a reinforcement pins 14 in the inner side at drive pin end 122.The both sides of drive pin end 122 are stamped with adding
Strong pin mounting hole 1221, installs reinforcement pins 14 and by being welded and fixed on the reinforcement pins mounting hole 1221.
In order to mitigate weight, the reinforcement pins 14 are a hollow reinforcement pins.
In order to mitigate the weight of brake-shoe 1 and improve radiating effect, the further lifting of braking effect is realized,
Some through holes 111 for mitigating weight and radiating are stamped with the brake-shoe mainboard 11.
Compared to traditional punch welding brake-shoe：
The present invention increases by a U-shaped reinforcement bridge plate at supporting pin end, then makes it with brake-shoe web by welding
Link together, it has advantages below：
1) brake drum is finally held to the reaction force of brake-shoe by the supporting pin end of brake-shoe during automobile brake
Load, thus brake shoe anchor bolt end be region of stress concentration, by weld a U-shaped reinforcement bridge plate, dispersive stress,
Braking safety is greatly improved；
2) by region of stress concentration local strengthening, and designed by cleverly loss of weight and (strengthen bridge plate middle part
It is provided with arch bridge opening), mitigate brake-shoe weight load；
3) by welding U-shaped reinforcement bridge plate and reinforcement pins, two brake-shoe webs are connected integral, it is to avoid long
Phase braking brake-shoe web spacing changes, and improves insensitivity.
4) by being stamped with some through holes for mitigating weight and radiating on brake-shoe mainboard, braking is alleviated
The weight and raising radiating effect of hoof, realize the further lifting of braking effect.
