Description
Technical field
Automobile brake technical field is the utility model is related to, particularly belongs to a kind of reinforced hot investment casting brakings of FS155
Hoof assembly.
Background technology
Brake-shoe refers to be pushed outwards exhibition by the effect of brake camshaft, and is pressed on its friction plate in brake drum
On disc.The brake-shoe not turned is roused to rotation brake and produces moment of friction, and braking is played so as to produce brake force compacting brake rim
The braking accessory of effect, it is installed on front steering section, is one of safe parts crucial in brake system of car.
China will be in January, 2018 discharge of cargo car forced use automatic adjusting arm, the in the market casting of old structure
Hoof, weight is overweight, weak heat-dissipating, is not suitable with the light-weighted demand of current vehicle.And brake-shoe poor rigidity is welded, thermal capacity is low,
Overheated in the course of work it is yielding, adjustment gap it is big the defects of, cause automatic adjusting arm to there is also toning in use
（Imbalance）Phenomenon, cause lock of controller, cause friction plate to overheat, the final security incident such as catch fire.
China Patent Publication No. is a CN202251568U utility model patent, discloses a kind of automobile-used drum brake
Hoof, it includes gusset and roller, installs roller at the roller end of gusset, the roller shaft both ends of the roller are fitted in gusset roller
In the half-arc groove at end；It is characterized in that：Gusset hole is additionally provided with gusset roller end, another to increase by a spring, one end of spring is
Circular arc or ring shape, are enclosed on the roller shaft of roller, the flexible leg of the other end of spring, in elasticity press-in gusset hole, lead to
Crossing spring makes roller connect into an entirety with welding brake-shoe；The gusset hole is to be symmetrical arranged two at gusset roller end,
The flexible feet of the spring other end has also been symmetrically formed two, respectively in two gusset holes of elasticity press-in.
Above-mentioned patent improves the safety coefficient after installation to a certain extent, but lacking for following tripartite face still be present
Fall into：
1st, the rivet hole of hoof panel is opened in the both sides of tendons of beef, mutton or pork plate, passes through countersunk head between hoof panel outer surface and friction plate
Semitubular rivet rivets, and riveting intensity is poor, reduces the braking effect of brake-shoe.
2nd, the overall rigidity of brake-shoe is poor, and tendons of beef, mutton or pork plate and hoof panel breakage occurs in long-term immobilization, causes malformation
And influence braking effect.
3rd, the weight weight of brake-shoe, aesthetic property is poor, easily occurs over control during use, causes brake-shoe locking,
Friction plate is caused to overheat, the final security incident such as catch fire.
Therefore, to adapt to lightweight market, my company have developed reinforced hot investment casting braking hoof, both alleviate brake-shoe
Overall weight, enhance the overall rigidity of brake-shoe again, improve the radiating effect of brake-shoe, be not in automatic adjusting arm
Imbalance（Toning）Phenomenon, the quick research and development of brake shoe assembly series of products are promoted, meets the needs of different main engine plants, is applied to
China is by the requirement of in January, 2018 discharge of cargo car forced use automatic adjusting arm.
The content of the invention
In view of the above-mentioned problems existing in the prior art, it is whole with brake-shoe to be to provide a kind of friction plate for the purpose of this utility model

To achieve the above object, the technical solution adopted in the utility model is as follows：
A kind of reinforced hot investment casting braking hoof assembly, hoof panel intrados is arranged in parallel in by the hoof panel of arc and two
Tendons of beef, mutton or pork plate be formed by connecting, tendons of beef, mutton or pork plate one end is supporting pin end, and the other end is drive pin end, described drive pin end and supporting pin
The end at end is respectively arranged with the first arc groove and the second arc groove；It is characterized in that：Described hoof panel inner surface four
Be provided with complete the first reinforcement for surrounding structure week, on the inside of the first reinforcement and positioned at hoof panel inner surface be provided with some groups and
The second vertical reinforcement of tendons of beef, mutton or pork plate；Described hoof panel inner surface and parallel to offering several on the center line of tendons of beef, mutton or pork plate
Rivet hole, hoof panel inner surface and is provided with two row's rivet holes positioned at tendons of beef, mutton or pork plate both sides are interleaved.
Further, described drive pin end is provided with the hanging bolt hole for installing retainer spring.
Further, described full encirclement structure is the rectangular configuration surrounded by the first reinforcement in hoof panel inner surface.
Further, the second described reinforcement is between the first reinforcement and tendons of beef, mutton or pork plate and between two tendons of beef, mutton or pork plates.
Further, coupled between described hoof panel and tendons of beef, mutton or pork plate by the first reinforcement, the second reinforcement and circular arc, led to
Cross and be cast integrally.
Compared to prior art, advantageous effects of the present utility model are：
1st, by setting up reinforcement in hoof panel inner surface, the overall rigidity of brake-shoe is enhanced, improves brake-shoe
Service life and braking effect.
2nd, by newly setting several rivet holes on the center line in hoof panel inner surface and parallel to tendons of beef, mutton or pork plate, enhance and rub
The overall riveting intensity of pad and brake-shoe, reduce riveting gap, improve above brake-shoe the service life of friction plate and
Braking effect.
3rd, at brake-shoe and friction plate riveting, wall thickness is suitably reduced, the overall weight of brake-shoe has both been alleviated, has carried again
The high radiating effect of whole product.
