Abstract
The invention discloses a kind of new anti-shearing brake block of NOA wear resistant and impact resistants, mechanical braking friction materials technology field.The composite abrasion resistance material includes fixed block, cushion, antifriction layer;The layer that rubs ensures that brake block has stable friction coefficient, good wear resistance；U-shaped cushion ensures that brake block has resistance to compression anti-shear performance；Cementing machine and pin make to form strong bond between brake block and wheel hub, apply it on electric bicycle and high-grade bicycle brake block, have good mechanical performance.
Description
Technical field
The invention belongs to mechanical braking friction materials technology field, and in particular to a kind of new NOA wear resistant and impact resistants resist
Shear brake block.
Background technology
As people's environmental consciousness is continuously improved, electric bicycle becomes a kind of popular vehicles, brake block
It is a vital part of electric bicycle braking system, its performance quality is directly related to personal safety.
Chief component-the brake disc and brake block of braking system, during the work time, the interaction on surface will cause surface
The loss and transfer of material, that is, produce abrasion so that the gap increase of brake friction pair, until brake disc and brake block lose work
Make ability.If from the aspect of safe and reliable, brake disc should have more preferable abrasion resistance properties, and brake block should then have higher
Friction coefficient, especially high temperature friction coefficient.However, excessive wearability also brings along certain negative effect, brake block it is resistance to
Mill property is better, and the shearing resistance for the generation that rubs is bigger, and the shear stress that contact top layer is born is bigger, so as to aggravate material
It is lost in.
There should be stable rub for the electric bicycle that F-Zero is 20km/h, its brake pad material in the prior art
Wipe coefficient（0.25~0.60）, good wear resistance（0~1. 00 × 10-7cm3 (Nm) -1）, enough mechanical property（
Shear strength at room temperature should be not less than 3MPa, and bond area should be not less than 80%）, low noise, safety and environmental protection etc..These performances
Influence each other, mutually restrict, take traditional hot moulding/rolling forming process to be difficult to coordinated balance, its main cause：Brake block
Internal material component and Tissue distribution are uneven, and especially reinforcing fiber is difficult to be uniformly mixed with powder, in addition, being pressed into using hot-die
When type or roll forming, brake block is overall block structure, and required drying time length, hot-die pressure are big, and bonding agent is difficult to fully
Flowing, product defect are more.
The content of the invention
The present invention is a kind of new anti-shearing brake block of NOA wear resistant and impact resistants, and applies it to electric bicycle and height
Shelves bicycle brake on piece, has good mechanical performance；The material includes fixed block, cushion, antifriction layer, and friction layer ensures
Brake block has stable friction coefficient, good wear resistance；U-shaped cushion ensures that brake block has resistance to compression shear resistant
Energy；Cementing machine and pin make to form strong bond between brake block and wheel hub, and microstructure is prepared accurately, and macroscopical comprehensive performance is excellent
It is good.
To achieve the above object, the present invention provides following technical solution：The present invention is that a kind of new NOA wear resistant and impact resistants resist
Brake block is sheared, which includes fixed block, cushion, antifriction layer.The fixed block is vulcanie body, by
Pin and bonding agent are fixed in brake block wheel hub, and the resistance to compression cushion is the U-shaped of 0.3-0.8mm by several thickness
Strengthen thin slice composition, the U-shaped enhancing thin slice is made of reinforcing fiber and elastic anti-ballistic materials, if the antifriction layer by
