Embodiment
With reference to figure 1, the blank of brake drum is shown, represents with reference character 10 hereinafter referred to as " bowl ".
By steel plate is carried out punching press and be cut into be roughly the radial coupling part 11 that columniform bowl 10 comprises plane substantially, described radial coupling part comprises: on the one hand, center hole 14 on unshowned hub for vehicle wheel, on the other hand, for receiving the perforation 13 axially fastening screw on described hub for vehicle wheel.Radial coupling part 11 by circular axial band 12 around, described circular axial band has outer diameter " D " and substantially constant thickness, and it comprises the friction surface for the formation of brake block (garniturede freinage).
Fig. 2 illustrates metal insert, and accompanying drawing marked price is 20, and the circular strip 21 made primarily of continuous print sheet metal is formed, and it has the constant cross section of thickness " e ".Metal insert 20 comprises the two row's perforation 25 be regularly distributed on the whole periphery of circular strip 21.Reference character 22 refers to the peripheral side edges that circular strip 21 is extended, its substantially with described circular strip 21 one-tenth 90 degree, namely slightly tilt relative to the radial direction of plug-in unit.
With reference to figure 3, according to the first number of assembling steps of the component part of brake drum of the present invention by metal insert 20 " fastening " is assemblied in bowl 10 circular axial band 12 exterior cylindrical surfaces on form.Should " fastening " assembling the resiliently deformable of 20 be divided to implement by metal insert.
The next step implemented according to brake drum of the present invention is described below with reference to Figure 4 and 5.The outer periphery surface of the assembly be made up of the bowl 10 assembled and metal insert 20 is by the wheel cylinder 30 of Overmolded reception aluminum or aluminum alloy, and it has the radial thickness " s " outside fitting flange or assembling rib.When carrying out Overmolded, the aluminum or aluminum alloy of wheel cylinder 30 fills perforation 25 until the circular axial band 12 of bowl 10.
Brake drum under Overmolded state shown in Fig. 7, has fitting flange or rib 30A.
Wheel cylinder 30 Overmolded after, the upper enforcement of the assembly (Fig. 8) after the assembling obtained thus supplements fine finishing.Especially, fine finishing can be implemented to only carrying out rough machined center hole 14 when manufacturing bowl 10, and finishing operations was carried out to the outer surface 30B in Overmolded portion 30.Grinding action can also be implemented to barrel surface 12B in the circular strip 12 rubbed for brake block.These fine finishing can obtain the precise geometrical feature of involved function surface, and may be out of shape during this Overmolded stage at wheel cylinder 30.
Connect in order to ensure the good mechanical of Overmolded wheel cylinder 30 on metal insert 20 and make this connection have good reliability, the various geometric of showing in the schematic diagram of Fig. 6 can adjust.Thus, these adjustment variablees in, can list the thickness " e " of axial length " X ", radial width " L " and metal insert 20, perforation 25 quantity and diameter
and the layout of perforation in circular strip 21.
Particularly, mode that can be regular by processing or punching formation perforation 25 is distributed in the many rows on the whole periphery of circular strip 21, such as, in two rows, as shown in Figure 2.Perforation 25 relative to the planar tilt of circular strip 21 or can not tilted.In addition, as modification, perforation 25 can not lateral alignment, but such as interlaced arrangement (en quinconce).
Also especially as shown in the schematic view of figure 6, the circular strip 21 forming metal insert 20 is conical, has when being in the position that metal insert 20 assembles on bowl 10 towards the comparatively Small Taper that the direction that the connection core 11 with bowl 10 is contrary is rotated.As to the nonrestrictive example of subject and the aspect(s) covered of the present invention, the angle " α " of this tapering can be approximately 5 °.
The operation of above-described brake drum is identical with the operation of casting conventional brake made of iron drum, and the heat that friction surface gives out to be stored in aluminium but not to be stored in cast iron.
Above-described brake drum has the following advantages:
-having benefited from metal insert and size thereof and operation characteristic, brake drum of the present invention has extraordinary mechanical strength and have accumulated the heat produced by drag friction well,
-it has thermal property and the mechanical property of the cast iron brake drum being equivalent to prior art while having actual quality income relative to brake drum of the prior art,
-it provides good dissipate heat when braking, better than " bi-material layers " brake drum of prior art, and
-Design and manufacture is simple, therefore has Economy.
