Description
Technical field
The utility model relates to hub for vehicle wheel art, refers in particular to an a kind of composite automotive wheel hub of hot melt cast molding.
Background technique
Conventional motor vehicle brake system comprises brake hub, brake shoe, arrestment mechanism etc., and when the automobile of traveling needs skidding, driver steps on braking footrest, arrestment mechanism promotes brake shoe, make shoes and brake hub produce braking friction, check automotive wheel, realize automobile brake.
Its entirety of current brake hub is generally iron material matter or steel matter; Its friction factor of the brake hub of iron material matter is large, and not easily skid, braking quality is good, but iron material matter gets rusty easily, and easily splits, and causes whole wheel hub short for working life; Although the brake hub of steel matter not easily gets rusty, steel matter friction factor is little, easily skids, and causes braking quality bad.
Therefore, be necessary to improve existing brake hub, to solve the problem.
Model utility content
In view of this, the utility model is for the disappearance of prior art existence, and its main purpose is to provide an a kind of composite automotive wheel hub of hot melt cast molding, and it effectively can solve existing brake hub and there is the problem that working life is short or braking quality is bad.
For achieving the above object, the utility model adopts following technological scheme:
A composite automotive wheel hub for hot melt cast molding, includes brake hub shell and multiple brake block; This brake hub shell and multiple brake block are hot melt casting matrix, this brake hub shell is steel matter, the plurality of brake block is the pig iron, the plurality of brake block is arranged on the inner ring wall of brake hub, each brake block is all fixedly connected with brake hub shell by screw, and this screw is screwed together fixing through brake block and brake hub shell.
As a kind of preferred version, the shape size of each brake block described is identical, and each brake block is arc sheet material.
As a kind of preferred version, described brake block is provided with fixed hole, accordingly this brake hub is provided with screw, this screw is connected with screwhole spiro bonding through fixed hole, and the head of screw is embedded in fixed hole completely.
As a kind of preferred version, between adjacent two brake blocks, be formed with gap.
As a kind of preferred version, the outer surface of each brake block described is burnishing surface.
As a kind of preferred version, between each brake block described and brake hub shell, be folded with thermal-protective coating.
The utility model compared with prior art has obvious advantage and beneficial effect, specifically, as shown from the above technical solution:
Brake hub shell is made by adopting steel matter, the pig iron is adopted to make brake block, and cooperation utilizes screw by brake block locking on the inner ring wall of brake hub shell, the brake hub shell of steel not easily gets rusty, and is beneficial to the working life extending product, and the brake block friction factor of the pig iron is large, not easily skid, braking quality is good, and the mode adopting screw to install, make the assembly and disassembly of brake block all very convenient, be convenient to safeguard.
For more clearly setting forth structure characteristic of the present utility model and effect, below in conjunction with accompanying drawing and specific embodiment, the utility model is described in detail.
Accompanying drawing explanation

Embodiment
Please refer to shown in Fig. 1 and Fig. 2, that show the concrete structure of first preferred embodiment of the utility model, include brake hub shell 10 and multiple brake block 20, this brake hub shell 10 and multiple brake block 20 are hot melt casting matrix.
Specifically, this brake hub shell 10 is steel matter, the plurality of brake block 20 is the pig iron, the plurality of brake block 20 is arranged on the inner ring wall of brake hub 10, each brake block 20 is all fixedly connected with brake hub shell 10 by screw 30, and this screw 30 is screwed together fixing through brake block 20 and brake hub shell 10.
In the present embodiment, the shape size of each brake block 20 is identical, and each brake block 20 is arc sheet material, this brake block 20 is provided with fixed hole 21, accordingly this brake hub 10 is provided with screw 11, this screw 30 is screwed together with screw 11 through fixed hole 21, and the head 31 of screw 30 is embedded in fixed hole 21 completely.And, be formed with gap 201 between adjacent two brake blocks 20, think that thermal expansion provides expansive space.In addition, the outer surface of each brake block 10 is burnishing surface 22.
During assembling, each brake block 20 is placed on the inner ring wall of brake hub 10, then, uses screw 30 to be screwed together through fixed hole 21 and screw 11, thus achieve the fixed installation of brake block 20.During dismounting, screw 30 unclamps and brake block 20 can be taken off from the outer side surface of brake block 20 by use instrument.
Please refer to shown in Fig. 3, that show the concrete structure of second preferred embodiment of the utility model, the concrete structure of the present embodiment is substantially identical with the concrete structure of aforementioned first preferred embodiment, and its difference is:
In the present embodiment, be folded with thermal-protective coating 40 between this each brake block 20 and brake hub shell 10, the heat on brake block 20 is passed on brake hub shell 10 and affects tire toe to utilize thermal-protective coating 40 to stop.
Design focal point of the present utility model is: make brake hub shell by adopting steel matter, the pig iron is adopted to make brake block, and cooperation utilizes screw by brake block locking on the inner ring wall of brake hub shell, the brake hub shell of steel not easily gets rusty, and is beneficial to the working life extending product, and the brake block friction factor of the pig iron is large, not easily skid, braking quality is good, and the mode adopting screw to install, make the assembly and disassembly of brake block all very convenient, be convenient to safeguard.
