Description
Technical field
The utility model is related to a kind of brake block with brake shoes attachment structure.
Background technology
In the prior art, truck drum-type brake pad and brake shoes connection rivet hole, present production technology is brake block
It is hot-forming after need using drilling machine by multiple rows of hole machined out, there is machining mould high cost, secondary positioning machining tolerance
Greatly, hole position is caused to be forbidden, it is difficult to wear rivet.Dust is produced in process simultaneously, causes environmental pollution, raw material and artificial
Cost increases.Heavy truck riveting brake shoes assembly, in brake producing producer and after-sales service market, external old part
Manufacture is repaired again, and all the time using iron, copper or aluminium rivet are by brake block and brake shoes hydraulic pressure or jam riveter
Riveting, small repair shop is even directly using tup manual rivet at home.When brake block is changed, because using process
Middle dust and get rusty, cause dismounting difficult.Unloading process easily causes that brake shoe iron loss is bad, and labor strength is high, time-consuming, takes
Power.The tightness of riveting cannot also be ensured by equipment limit simultaneously, loosing of rivet is easily produced, shear strength and moment of torsion all cannot
Meet use requirement, exist during use, because loosing of rivet produces brake block to come off and dawdled with brake drum causing
Brake block rapid wear, serious brake failure, causes security incident.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of dismounting simply and bonding strength brake block high
With brake shoes attachment structure.
The technical scheme that the utility model is used is：A kind of brake block and brake shoes attachment structure, it includes brake
Shoes, brake block, the nut being embedded in brake block and for being fixedly connected with will brake shoes and brake block of nut screw connection
Connecting bolt；The upper surface outer rim of the nut is circumferentially arranged locking hangnail, the locking hangnail direction brake shoes
Side, and the locking hangnail is provided with the card being adapted with nut shape to the inclination of nut axis on the brake block
Connect hole.
The upper surface is evenly arranged with clamp, and the outer rim camber line of multiple clamps is concentric circles, the locking hangnail
It is arranged on clamp.
Multiple clamps are successively set on upper surface in counter clockwise direction.
Good effect of the present utility model is：The direct embedded nut in brake block, by connecting bolt by brake block with
Brake shoes connection, rational in infrastructure, simple to operate, bonding strength is high, and is saved material in brake flat production process, system
Manufacturing accuracy is high；Be able to can be attached using torque spanner in connection procedure, convenient and strength-saving without equipment investment, joint efficiency
Height, and attaching nut need to only be pulled down during secondary dismounting, secondary dismounting is simple；In use, rubbing surface simultaneously
There is no rivet hole, increase the contact area with brake drum, improve brake force, increase the service life.It is provided with nut locking
Hangnail, can effectively prevent nut from loosening vertically in use, while clamp can effectively prevent nut from occurring
Rotation, locking hangnail and clamp synergy, nut are secured firmly in blocked hole, dependable performance, and connection is more consolidated.

Fig. 3 is the locking barb structure schematic diagram of the utility model；
Fig. 4 is the utility model clamp structure schematic diagram.
In the accompanying drawings, 1- brake shoes, 2- brake blocks, 3- nuts, 301- upper surfaces, 302- clamps, the locking hangnails of 303-,
4- connecting bolts.
Specific embodiment
As shown in accompanying drawing 1-4, the utility model includes brake shoes 1, brake block 2, the nut 3 being embedded in brake block 2
And for coordinating the connecting bolt 4 for being fixedly connected brake shoes 1 and brake block 2 with nut 3；The upper surface of the nut 3
301 outer rims are circumferentially arranged a locking hangnail 303, and the locking hangnail 303 is towards brake shoes 1 side and described locking
Hangnail 303 is connected one end to the other end gradually to the axis inclination of nut 3, multiple locking hangnails 303 along with upper surface 301
Outline formed taper, the blocked hole being adapted with the shape of nut 3 is provided with the brake block 2.Tapered setting
Nut can effectively prevent nut in use from producing axial play.
The upper surface 301 is evenly arranged with clamp 302, and clamp 302 is in windmill, is uniformly arranged on upper surface 301
Outer, is provided with the draw-in groove corresponding with clamp 302 on blocked hole, and clamp 302 is arranged in draw-in groove, multiple clamps
302 outer rim camber line is concentric circles, and the locking hangnail 303 is arranged on clamp 302.
The overlook direction of nut 3 as shown in Figure 4, multiple clamps 302 are in counterclockwise deflection is arranged on successively
On upper surface 301.
The utility model is used by the embedded nut in brake block 2, so as to realize being connected with brake shoes 1, not only may be used
To save the cost of raw material that feeds intake, production equipment is reduced, reduce secondary operation environmental pollution, improve Product Precision, practicality is high.
Labour intensity is particularly reduced in after-sales service and during reparation, convenient disassembly eliminates the secondary damage to the shoes that brakes,
Improve production efficiency.Installation process reduces equipment investment, connects uniform force, and shear strength is greatly improved.
