Abstract
The invention discloses a brake block of an electrombile. The brake block comprises an arc-shaped iron support and an arc-shaped iron sheet mounted on the peripheral face of the arc-shaped support, wherein a friction material is also arranged on the surface of the arc-shaped iron sheet; two ends of the arc-shaped iron support are respectively provided with an aluminum alloy fixing block with a concave groove and a planar aluminum expanding block through a casting way; and a wearable sheet is wrapped on the external end of the planar part of the expanding block. The brake block is high in precision manufacture, simple in technology, and easy to manufacture.
Description
?
Technical field
The invention belongs to electric vehicle brake systems technology field, relate in particular to the brake block in the brake system.
Background technique
The a large amount of modes that rise and stop that adopt of the brake system of electric motor car at present have advantage simple in structure, that cost is low.As shown in Figure 1; A kind of aluminum alloy integral type brake block; Adopt the aluminum alloy integral die-cast or be cast into incorporate brake block structure, it mainly comprises support, film hanger rack, friction material, spreading piece and fixed block, and wherein film hanger rack is located on the curved circular side face of support; And on its surface friction material is set, and spreading piece and fixed block are located at the two ends of support.Not only manufacture cost is high, working life is short for this incorporate aluminium alloy structure, and diecasting alloys are softer, are difficult to be fixed together with the high-quality friction material.Also there is a kind of modified model brake block in the market; As shown in Figure 2; It comprises retort stand, and these retort stand two ends are provided with the hole, and the both sides up and down of an end are provided with respectively and add chunk therein; Adding the outer fixed block cover that coats the band recess of chunk then, thereby and pass the hole through Liu Ding and be fixed and form fixed block; The other end of retort stand then is provided with in both sides up and down equally and adds chunk, and puts the spreading piece cover of plane adding the chunk outer periphery, utilizes the hole on the Liu Ding perforation retort stand equally, is fixed on formation spreading piece on the retort stand thereby will add chunk with spreading piece cover.This structure has solved the fixation problem between film hanger rack and the friction material, but structure is very complicated, and precision is difficult to guarantee, causes braking effect unstable easily.
Summary of the invention
Goal of the invention: to the problem of above-mentioned existing existence and not, not the purpose of this invention is to provide a kind of electric vehicle brake piece, not only precision is very high has more stable braking effect for it, and technology is simple.
Technological scheme: for realizing the foregoing invention purpose; The present invention adopts following technological scheme: a kind of electric vehicle brake piece; Comprise arc retort stand and arc iron plate, said arc iron plate is located on the outer peripheral surface of curved support, and its surface also is provided with friction material; Said arc retort stand two ends are respectively equipped with the aluminum alloy fixed block of band groove and the aluminum alloy spreading piece of plane through forging type, and the plane outer end of said spreading piece is coated with anti-abrasive disc.
Further improve, the two ends of said arc retort stand are provided with through hole.
Further improve, the inboard and the outside at the two ends of said arc retort stand are equipped with recess.
Beneficial effect: compared with prior art, the present invention has the following advantages: accuracy of manufacturing is high, and technology is simple, makes very easily.

Wherein, arc retort stand 1, arc iron plate 2, friction material 3, fixed block 4, spreading piece 5, anti-abrasive disc 6, through hole 7, recess 8.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment; Further illustrate the present invention; Should understand these embodiments only be used to the present invention is described and be not used in the restriction scope of the present invention; After having read the present invention, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the present invention.
Like Fig. 3 and shown in Figure 4; A kind of electric vehicle brake piece comprises arc retort stand 1 and arc iron plate 2, and said arc iron plate 2 is located on the outer peripheral surface of curved support; And its surface also is provided with friction material 3; Said arc retort stand 1 two ends are provided with through hole 7, form the fixed block 4 of band groove and the spreading piece 5 of plane respectively through the disposable casting of pack alloy then, coat anti-abrasive disc 6 at last in the plane outer end of opening piece.
As shown in Figure 5, present embodiment with embodiment 1 different place is: before die casting was carried out at arc retort stand 1 two ends, the inboard at its two ends and the outside were provided with recess 8 respectively, thereby made the fixed block 4 of follow-up die casting be connected more firm with spreading piece 5.
The present invention is provided with diecasting alloys through the two ends of retort stand, with arc retort stand 1, and fixed block 4, spreading piece 5, anti-abrasive disc 6 is fixed as one, and not only accuracy of manufacturing is high, and technology is simple, makes very easily.
