Abstract
The invention relates to a corner hinger, which can hinge two components, comprising a hinger spherosome and a round cavity. Wherein, the first fixer is mounted on the hinger spherosome for linking it to the first component, and this round cavity with the second fixer for fixing the second component at least partly surrounds the hinger spherosome. The fixer on the hinger spherosome can rotate at least in a certain angle surrounding an optimum axis, and can oscillate related to the second fixer. For the destination of a corner hinger which has a hinger spherosome mounted simply and reliably and can be produced easily, the invention designs a backing member (8) in the round cavity (6), which has a containing space (15) for the hinger spherosome (2), a sliding surface (23) supporting the hinger spherosome (2) movable, a shape lock unit (25) connecting the backing member (8) as a whole for fixing it in the round cavity (6), and a self-locking shape lock unit (21) for fixing the hinger spherosome (2) in the backing member (8).
Description
Technical field
The invention belongs to brake block, particularly a kind of automobile brake sheet that adopts low metal abrasives.
Background technique
Automobile is being brought into play more and more important effect as transport facility in national economy and people's social life.Develop rapidly along with car industry, a series of new requirements and problem have also appearred simultaneously, concentrated reflection is Security, travelling comfort, the feature of environmental protection, the brake portion of this three property and automobile is closely related, automobile brake sheet is the critical component of brake portion, its performance how, directly determining braking ability.Present domestic brake block is divided by the friction material of its use two kinds: a kind of be asbestos abrasives brake block, a kind of be semimetal abrasives brake block.Asbestos brake lining mainly contains asbestos, and asbestos content is about 30-45%, because of causing environmental pollution, country has determined to eliminate this kind brake block, and another kind is a semi-metallic brake pad, and its tenor surpasses 40%, shortcoming is tenor height such as invar fiber, easily produces noise, easily gets rusty.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art, develop a kind of non-environmental-pollution, the good brake block of the little attriting performance of noise.
The realization the technical solution adopted in the present invention is as follows: component of the present invention is phenolic resin, Steel Fibre, non-asbestos fiber, barium sulphate, friction powder, stabilizing and curing agent, increases grinding agent, anti-friction composition, the copper fiber; Each components contents is: by weight

Non-asbestos fiber: for wear-resisting, the fiber that resistance to high temperature is good is as Na Kaifu fiber, wollastonite fibre, carbon fiber, ceramic fiber.
Manufacture method of the present invention is that concrete steps are as follows with hot-forming after the each component raw material mixing and stirring:
(1) takes by weighing raw material by prescription;
(2) will stir mixing time 6-8 minute after the each component mixing;
(3) mixture of mixing thoroughly is poured into and is carried out hot-forming processing in the mould.Molding time is decided on the product of various different sizes between 10-25 divides, press temperature 155 degree.
(4) sulfuration steady heat treatment temperature 160-180 degree, 8 hours time;
(5) put in order after grooving, chamfering, the grinding;
(6) electrostatic spraying after-baking, heat treatment temperature 120 degree, time 40-60 minute;
Good effect of the present invention is: said components and content, preparation method are that the inventor has carried out drawing on the basis of a large amount of tests, through use proof on automobile following advantage are arranged:
(1) its friction ractor is stable especially under all temps condition, all between 0.36-0.37.
(intensification)
(2) wear rate promptly uses the life-span longer well below GB.
(3) there is not noise.
