Abstract
The invention relates to a less-metal brake pad and a production process thereof, and relates to the technical field of brake pads. The less-metal brake pad comprises a steel backing and a friction material, wherein the friction material consists of aramid fibers, resin, copper fibers, friction powder, crystalline flake graphite, molybdenum disulfide and barite. The production process comprises the following steps of: weighing the raw materials, mixing the raw materials, pressing for forming, treating the steel backing, pressing by using a pressing machine, treating at the later stage and installing accessories to produce the brake pad serving as a finished product. The less-metal brake pad is simple in structure, modular in design, low in production cost, good in braking effect, stable in friction coefficients, moderate in wear rate and high in heat fading resistance, can meet the requirements of miniaturized and large-scale production simultaneously and does not have noise in the braking process.
Description
Technical field:
The present invention relates to brake block processing art field, be specifically related to a kind of micro-metal brake pad with and production technology.
Background technique:
Brake block also is brake rubber block.In the brake system of automobile, brake block is the breaking piece of most critical, and the quality of all braking effects all is that brake block plays a decisive role, so the brake block of agreeing is the patron saint of people and automobile.Brake block generally is made of steel plate, bonding thermal-protective coating and brake pad.Wherein thermal-protective coating is comprised of adiabatic material, and purpose is heat insulation.Brake pad is comprised of friction material, tackiness agent, is compressed in during brake to produce friction on brake disc or the brake drum, thereby reaches the purpose of vehicle deceleration brake.
General brake block can be divided into asbestos type brake block, semipermanent mold brake block.The friction material of asbestos type brake block mainly is take asbestos fiber as main, yet asbestos are harmful materials, and braking effect is poor.The friction material of semipermanent mold brake block be with coarse Steel Wool as reinforced fibers and important mixture, need in use higher retardation pressure, produced simultaneously noise is larger.
Exist certain defective in the method for the brake block production of adopting now,, cycle higher such as cost of production, length, trimmed size disunity, yield rate were low.
Summary of the invention:
Technical problem solved by the invention is to provide one, and to produce cost low, uniform specification, good braking effect, noise is little, to the nontoxic micro-metal brake pad of environment, human body with and production technology.
Technical problem solved by the invention realizes by the following technical solutions:
A kind of micro-metal brake pad comprises steel backing and friction material, it is characterized in that: described friction material is made by the raw material of following weight percentage:
A kind of production stage of micro-metal brake pad is as follows:
A, take by weighing raw material and take by weighing accurately aramid fiber, resin, copper fiber, friction powder, crystalline flake graphite, molybdenum disulfide, barite by raw material components;
B, mixed material are put into the raw material that weighs up in the batch mixer and are mixed, and incorporation time is 5-10 minute;
C, compressing behind the compressing formation brake pad of mixed prepared using mould takes out for subsequent use;
D, steel backing are processed steel backing cleaning, ball blast are being sprayed glue after drying;
The steel backing that the compacting of e, press will be handled well and compressing brake pad are pressed into brake by press;
F, post-processed with brake block with drying oven on forced convection heat, polishing, flat stone mill process, the chamfering of then slotting is as required carried out whole brake block ablation processes and is sprayed chalk line;
G, annex are installed and are utilized rivet that annex is installed on the brake block.
The beneficial effect that the present invention has is: what the present invention relates to is simple in structure; modular design; can satisfy simultaneously microminiaturized and the large production requirement of scale; cost of production is lower; braking effect is good, friction factor comparatively steadily, noiseless, heat resistanceheat resistant decline better performances in moderate, the braking process of wear rate.
Embodiment:
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with specific embodiment, further set forth the present invention.
Embodiment
Take by weighing accurately aramid fiber 6%, resin 8%, copper fiber 20%, friction powder 10%, crystalline flake graphite 26%, molybdenum disulfide 5%, barite 25% by raw material components; The raw material that weighs up put in the batch mixer mix, incorporation time is 5-10 minute; Behind the compressing formation brake pad of mixed prepared using mould, take out for subsequent use; Steel backing cleaning, ball blast are being sprayed glue after drying; The steel backing handled well and compressing brake pad are pressed into brake by press; With brake block with drying oven on forced convection heat, polishing, flat stone mill process, the chamfering of then slotting is as required carried out whole brake block ablation processes and is sprayed chalk line; Utilize rivet that annex is installed on the brake block.
The brake block that makes is placed on the constant speed experimental machine tests, the result is as shown in table 1.
Can find out from table 1 data, the friction factor of the brake block that the embodiment of the invention obtains changes very little.In the temperature rise period, friction factor is at 0.31-0.44, and at 0.25-0.39, wear rate is little at the temperature-fall period friction factor, is stabilized in 0.08-0.2*10
-7Cm
3/ N.m is up to state standards.Use through numerous vehicles, braking effect is good, friction factor comparatively steadily, noiseless, heat resistanceheat resistant decline better performances in moderate, the braking process of wear rate.
Above demonstration and described basic principle of the present invention and major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
