Description
Technical field
The utility model relates to a kind of braking system part, is specifically related to a kind of brake-shoe knot in brakesStructure.
Background technology
As shown in Figure 1, existing drum brake system mainly includes brake drum 2, brake strip 3, systemMoving hoof 1`, brake shoe anchor bolt 4, brake-shoe drive pin 5, retainer spring 6 and brake camshaft 7.When automobile brake brake drum 2 to the reaction force of brake-shoe 1` finally by the supporting pin end 121 of brake-shoe 1`Bear, therefore brake shoe anchor bolt end 11 is region of stress concentration. As shown in Figure 2, brake-shoe 1` structure comprisesBrake-shoe mainboard 11 and brake-shoe web 12, one end of brake-shoe web 12 is supporting pin end 121, anotherEnd is drive pin end 122, and described supporting pin end 121 is provided with the supporting pin half for brake shoe anchor bolt 4 is installedOpening seat 1211 and for the spring eye 1212 of retainer spring 6 is installed. Existing brake-shoe 1 is propping upThe structure of support pin end 121 is thiner, and concentrates under environment at long-term stress, easily occurs fatigue deformationAnd scrap. And long-term immobilization can cause brake-shoe web 12 spacing to change, cause malformation andAffect braking effect. In addition, because existing brake-shoe mainboard 11 is single plank frame, its weight large andWeak heat-dissipating, braking effect cannot further promote.
Utility model content
The purpose of this utility model is for the problems referred to above, not in part, to provide a kind of reinforced punch weldingBrake-shoe, it improves the structural strength of supporting pin end, avoids brake-shoe web spacing to change, and has improvedThe service life of brake-shoe and braking effect.
In order to achieve the above object, the utility model is by the following technical solutions:
A kind of reinforced punch welding brake-shoe, comprises brake-shoe mainboard and brake-shoe web, brake-shoe webOne end be supporting pin end, the other end is drive pin end, described supporting pin end is provided with for brake-shoe is installed and props upThe supporting pin half opening seat of support pin and for the spring eye of retainer spring is installed, described brake-shoe webBe welded with a U-shaped reinforcement bridge plate in the inner side of supporting pin end, described U-shaped reinforcement bridge plate comprises that two are welded on systemThe reinforcement side plate of the supporting pin end of moving hoof web and be connected between two reinforcement side plates and strengthen bridge plate, described two addStrong side plate is respectively equipped with the reinforcement half opening seat matching with half opening seat and the reinforcement bullet matching with spring eyeSpring hole.
Further, described two strengthen side plate and strengthen bridge plate being integrated punch forming.
Described reinforcement bridge plate middle part is provided with arch bridge opening, and the effect of this arch bridge opening is both to have alleviated reinforcement bridgeThe weight of plate, can strengthen again and strengthen bridge plate to resistance to compression bending strength.
In order to alleviate the weight of brake-shoe and to improve radiating effect, realize the further lifting of braking effect, instituteState brake-shoe mainboard upper punch and be pressed with some through holes for weight reduction and heat radiation.
The utility model carries out structural improvement to brake-shoe innovatively, at supporting pin end, U-shaped reinforcement bridge is setPlate, it improves the structural strength of supporting pin end, avoids brake-shoe web spacing to change, and has improved brakingThe service life of hoof and braking effect.

Detailed description of the invention
As shown in Fig. 3 to 5, the reinforced punch welding brake-shoe 1 of one described in the utility model, comprises systemMoving hoof mainboard 11 and brake-shoe web 12, one end of brake-shoe web 12 is supporting pin end 121, the other endFor drive pin end 122, it is half-open that described supporting pin end 121 is provided with supporting pin for brake shoe anchor bolt 4 is installedMouthful seat 1211 and for the spring eye 1212 of retainer spring 6 is installed.
In order to increase the intensity of supporting pin end, described brake-shoe web 12 is in the welding of the inner side of supporting pin end 121Have a U-shaped reinforcement bridge plate 13, described U-shaped reinforcement bridge plate 13 comprises that two are welded on propping up of brake-shoe web 12Support pin is held 121 reinforcement side plate 131 and is connected between two reinforcement side plates 131 and strengthens bridge plate 132, described twoStrengthen side plate 131 and be respectively equipped with the reinforcement half opening seat 1311 and and the spring that match with half opening seat 1211The reinforcement spring hole 1312 that hole 1212 matches.
Further, described two strengthen side plate 131 and strengthen bridge plate 132 being integrated punch forming.
Described reinforcement bridge plate 132 middle parts are provided with arch bridge opening 1321, and the effect of this arch bridge opening 1321 is both canTo alleviate the weight of strengthening bridge plate 132, can strengthen again and strengthen bridge plate 132 to resistance to compression bending strength.
In order to alleviate the weight of brake-shoe 1 and to improve radiating effect, realize the further lifting of braking effect,Described brake-shoe mainboard 11 upper punches are pressed with some through holes 111 for weight reduction and heat radiation.
Compare traditional punch welding brake-shoe:
The utility model increases by a U-shaped reinforcement bridge plate at supporting pin end, then makes itself and brake-shoe by weldingWeb links together, and it has the following advantages:
1) brake drum is finally brought in and is held by the supporting pin of brake-shoe the reaction force of brake-shoe when automobile brakeLoad, therefore brake shoe anchor bolt end is region of stress concentration, by welding a U-shaped reinforcement bridge plate, dispersive stress,Greatly improve braking safety;
2) strengthen by counter stress concentrated area is local, and (strengthen bridge plate middle part by loss of weight design cleverlyBe provided with arch bridge opening), alleviate brake-shoe weight load;
3) by the U-shaped reinforcement bridge plate of welding, two brake-shoe webs are connected into entirety, avoid long-term immobilization systemMoving hoof web spacing changes, and improves insensitivity.
4) be pressed with some through holes for weight reduction and heat radiation by brake-shoe mainboard upper punch, alleviated brakingThe weight of hoof and raising radiating effect, realize the further lifting of braking effect.
