Abstract

The invention provides a brake disc. The brake disc comprises an outer disc, an inner disc and a plurality of positioning parts, wherein the outer disc is annular, and is defined with an axial direction; a plurality of connection bridges which are arranged at intervals and extend towards a middle axle are formed on the inner ring edge of the outer disc; the free ends of the connection bridges are provided convex parts; through holes are formed in the convex parts in the axial directions; the inner disc is coaxially arranged in the center of the outer disc and is positioned on the same plane with the outer disc; a plurality of concave parts which are arranged at intervals are arranged in the outer ring edge of the inner disc; the plurality of concave parts correspond to the plurality of convex parts respectively; the convex parts are just embedded into the concave parts to avoid rotation of the inner disc relative to the outer disc; a gap is formed between each concave parts and each convex part; each positioning part passes through the corresponding through hole to limit relative movement of the outer disc and the inner disc along the axial direction; the outer disc and the inner disc are not overlapped in the axial direction at all. The brake disc is a floating brake disc which has a good heat-insulating effect and high structural strength.

Description

Brake rotor

Technical field

The invention relates to a kind of brake rotor, espespecially a kind of float-type brake disc.

Background technique

Known brake rotor mostly is one chip, and brake action is carried out for clamp clamping in its outer ring, and middle body is for linking with dynamic with flower hub, but the high heat produced of braking in this class formation can be passed to colored hub via disc and produce harmful effect.

Therefore, there is a kind of two-piece type combination brake rotor, comprise to supply the inner disc linked with flower hub and the outer disk clamped for clamp, outer disk central authorities have perforate and arrange for inner disc, fix with multiple locating piece between the two, use and reduce the high heat transfer of brake generation to flower hub, wherein, the outer disk of a class and inner disc is had partly to be stacked each other and to pass this outer disk and inner disc with locating piece simultaneously, as TaiWan, China patent 451855, I318188, M473983, the described person such as M473984, this class formation must be bored a hole respectively in outer disk and inner disc, and outer disk and inner disc area of contact are still quite large, insulation effect is not good, in addition, in, outer disk is only fixed to one another by locating piece, structural strength is more weak.

In addition, separately there is a kind of floating type disc, as TaiWan, China patent 335113, I404643, M243588, M271985, M306566, M386212, M409216, the person of taking off such as M451445, in having equally, outer disk, but in conjunction with mode be in interior, outer disk is respectively equipped with a recess or U-shaped portion, and both recess are enclosed structure one perforation toward each other jointly, perforation is through at again fixing with locating piece, though this class formation has good insulation effect compared with the structure described in epimere, but in locating piece is sandwiched in, between outer disk, heat still may be passed to inner disc via locating piece, in addition, in avoiding, outer disk rotates relatively, recess or U-shaped portion must design especially and engage with each other, just may cause cannot use once the error had in size, and, after permanent use, the outer rim of recess may heavy wear, affect structural strength and safety in utilization.

Summary of the invention

Object of the present invention, is to provide a kind of brake rotor, possesses the advantage of float-type brake disc, have again preferably structural strength.

For achieving the above object, the present invention is by the following technical solutions:

A kind of brake rotor, it comprises:

One outer disk, generally a perforation is formed in link spring shape in its central authorities, this perforation defines an axis, this axis defines an axial direction, this outer disk has an interior ring edge, this interior ring edge encloses this perforation of structure, the interior ring edge of this outer disk is formed with a plurality of spaced connecting bridge, respectively this connecting bridge extends to form towards the central axis direction radial direction of this perforation, this connecting bridge has a bump compared with the one end away from this outer disk interior ring edge, this bump axially wears a perforating, has the intended distance in radial direction between this bump and interior ring edge of this outer disk;

One inner disc, this inner disc is coaxially arranged at the perforation of this outer disk and in the same plane with this outer disk, this inner disc intermediate portion has a flower hub linking department, this inner disc also has an outer ring edge, this outer ring edge is provided with a plurality of spaced reentrant part, this a plurality of reentrant part respectively bump a plurality of with this is corresponding, this reentrant part axially runs through this inner disc, this reentrant part shape and this bump to be generally embedded in this reentrant part to avoid this inner disc to rotate relative to this outer disk in corresponding this bump that makes just, form a gap between this reentrant part and this bump;

A plurality of locating piece, respectively this locating piece is arranged in this perforating to limit this outer disk and the in axial direction relative movement of this inner disc;

Wherein, this outer disk and this inner disc are completely not overlapping in the axial direction.

In a preferred embodiment, described connecting bridge generally comprises in Y-shaped two foots and this bump that are connected with this outer disk interior ring edge.

In a preferred embodiment, described inner disc comprises an outer portion, a plurality of bridge portion and this flower hub linking department, and respectively this bridge portion extends towards this flower hub linking department relative to the position of this reentrant part from the interior ring edge of this outer portion and is connected between this outer portion and this flower hub linking department.

In a preferred embodiment, each described locating piece comprises one first positioning component and one second positioning component, this first positioning component has a bar portion and the head being positioned at wherein one end, this bar portion, this first positioning component is combined with this second positioning component through after this perforating with this bar portion, make the head of this first positioning component lay respectively at the relative both sides of this outer disk with this second positioning component, and the head of this first positioning component and this second positioning component are all greater than this reentrant part and this bump and are covered this reentrant part and this bump.

Beneficial effect of the present invention is: be embedded in reentrant part because bump is whole, therefore can effectively prevent inside and outside dish from relatively rotating, and comparatively certain in braking conduction, not easily weares and teares because using for a long time again and even loses limit effect; On the other hand, outer disk and inner disc are underlapped in the axial direction, insulation effect can be improved, and locating piece extends only through outer disk and does not pass inner disc, therefore locating piece does not contact inner disc completely, heat can be avoided to conduct to inner disc through locating piece, in other words, only across a gap between outer disk and inner disc, can effectively dispel the heat by this gap and prevent heat from continuing to reach inner disc.
