Detailed description of the invention

It should be noted that in the case of not conflicting, in embodiment in this utility model and embodiment Feature can be mutually combined.

Describe this utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.

Embodiment one

The present embodiment relates to a kind of automobile brake disc, and by shown in Fig. 1 to Fig. 3, it includes matrix 1, matrix 1 For plate-like, and being made up of aluminum alloy material, be provided with installing hole 2 on matrix 1, installing hole 2 is for base The body 1 installation on wheel.In the present embodiment, matrix 1 constitutes the main body of brake disc, and on matrix 1 It is additionally provided with potsherd 3, with the wearability of available potsherd 3, and improves the performance of brake disc.

In the present embodiment, potsherd 3 is multiple with the enhancement mode of SiC synthesis by carbon fiber under 1700 DEG C of high temperature Close pottery, and potsherd 3 is for together with being cast in matrix 1 when matrix 1 moulding by casting.Such as institute in Fig. 3 Show, the present embodiment is formed on matrix 1 for rubbing mutually with the friction plate on caliper, so that wheel system Dynamic work surface 5, and also there is the first end face 6 of the thickness direction formation along potsherd 3 at potsherd 3 With the second end face 8, the first end face 6 of potsherd 3 is in same plane with the work surface 5 of matrix 1, To together constitute the end face with the friction plate frictional damping on caliper in brake disc.

In the present embodiment, the second end face 8 of potsherd 3 gos deep into the inner side of matrix 1 relative to work surface 5, Matrix 1 is also formed with the binding face 7 that the second end face 8 with potsherd 3 fits, binding face 7 with Shape is in the second end face 8, namely the configuration of binding face 7 is identical with the second end face 8 of potsherd 3.This enforcement In example, the second end face 8 of potsherd 3 being designed to plane, the binding face 7 on matrix 1 is plane the most therewith, Except of course that be plane, the second end face 8 of potsherd 3 may be used without the curved surface with convex or concave part, Binding face 7 on matrix 1 then follows the difference of the second end face 8 and changes.

As shown in Figure 3, in the present embodiment potsherd 3 also for be arranged to, by multiple, the pottery that crossings on different level is netted Porcelain unit 9 is constituted, and cancellated two opposite ends of crossings on different level that multiple ceramic unit 9 are constituted all add Work becomes plane, to form the first above-mentioned end face 6 and the second end face 8.Certainly, foregoing, Biend 8 is except plane, it is possible to be processed into curved surface.When matrix 1 moulding by casting, first will spatially intersect Netted potsherd 3 is placed in the die cavity of casting mold, then injects in die cavity by aluminium alloy liquid, and aluminum closes Gold liquid can enter in the gap between each ceramic unit 9 in potsherd 3, can make after cooling and shaping Become brake disc as shown in Figure 1.

During the end surface shape of ceramic unit 9 may be configured as circle, ellipse or polygon in the present embodiment one Planting or multiple, the as above design of ceramic unit 9 end surface shape can improve the wearability of brake disc work surface.By Fig. 1 combines shown in Fig. 2, between the structure of the work surface 5 forming both sides in the present embodiment on matrix 1 also Being provided with heat-sink unit 4, heat-sink unit 4 is spaced multiple, and heat-sink unit 4 in the present embodiment Also arranged in a crossed manner with the RADIAL of matrix 1, the surface area of the heat-sink unit that so can make is relatively big, thus improves Its radiating effect.

In the present embodiment, heat-sink unit 4 is that cast is formed at the aluminium alloy structure on matrix 1, certainly Heat-sink unit 4 is alternatively after matrix 1 moulding by casting, then the aluminum being connected in matrix 1 by heat-conducting glue is closed Gold bullion or other there is the metal derby of excellent heat dispersion performance.Except making the RADIAL of heat-sink unit 4 and matrix 1 Arranged in a crossed manner, certain heat-sink unit 4 also can be arranged as other form on matrix 1.Pottery in the present embodiment Also it is that concentrically line is arranged, with so that brake disc has preferable dynamic balance between sheet 3 and matrix 1. And potsherd 3 is also configured to annular in the present embodiment, it is the most circular, oval, hexagon or The polygons such as rhombus, and other is irregularly shaped etc..

The annular of potsherd 3 arranges and can ensure that the first end face 6 of potsherd 3 is on the work surface 5 of matrix 1 It is evenly distributed, to improve brake disc braking ability, and improves the bulk strength of brake disc rubbing surface, and also may be used The hot tearing effect avoiding brake disc surface stress skewness and cause.Except using aluminum to close in the present embodiment Gold material, matrix 1 also can by the light metal such as almag, titanium alloy cast make, and potsherd 3 except Netted for the crossings on different level together with being cast in matrix 1, potsherd 3 may be used without solid construction, and at base Together with being cast in matrix 1 when body 1 is poured into a mould.Certainly, except making together with potsherd 3 is cast in matrix 1, The potsherd 3 of solid construction also can be connected with matrix 1 by the way of inlaying or be cementing.

This automobile brake disc may utilize, by arranging potsherd 3, the abrasive resistance that potsherd 3 is had, and improves The service life of brake disc, by making matrix 1 be made up of aluminum alloy material, the lightweight of available aluminium alloy And high heat capacity and heat-sinking capability, and while reducing brake disc weight, it is also possible to reduce brake disc temperature, Avoid brake disc heat fading, to improve the braking safety of brake disc.This automobile brake disc is by using pottery Sheet 3, and make together with potsherd 3 and matrix 1 be fixed on through cast, it is possible to utilize potsherd 3 for entirety The feature of structure, improves brake disc machining accuracy and the dynamic balance performance of brake disc, and it also can be easy to pottery simultaneously The ceramics 3 setting on matrix 1, thus facilitate the processing of brake disc, to improve brake disc production efficiency.

Embodiment two
