Description
Technical field
The invention belongs to brake block manufacturing field, the manufacture more particularly to a kind of automotive brake pads and test technology.
Background technology
As the raising of car speed, the increasing of loading capacity, environmental consciousness are increasingly enhanced, automobile industry is to braking brake
The comprehensive performance of piece also proposed increasingly higher demands.
There are many performance indicator of brake block, and the same brake block is in feelings such as different temperatures, different speeds, different braking pressure
Performance under condition is very different, and main performance has the following：
1. braking ability；Refer under normal brake application state (the namely relatively low situation of brake temperature), brake block
Stopping power (friction coefficient)；
2. fail performance:Under the road conditions of hill path descending etc, brake is continuously braked, and temperature rises rapidly, brake block
Stopping power can be deteriorated, braking distance increase.This phenomenon is " decline ".High-quality brake block fading rate very little, or even do not wane
It moves back；And the decline of certain low-quality goods is serious, when high temperature, almost loses stopping power；
3. restorability:By the brake block that high temperature fails, upon a drop in temperature, if original braking can be restored as early as possible
PerformanceThis is also the important indicator for weighing brake block quality；
4. abrasion:Refer in abrasion condition when brake block uses；
5. noise:Cause the factor of brake noise many in fact, brake block is one of them.It is generally believed that brake block
If hardness is too high, it is easy for generating noise；
6. other shear strength, compression strength, hardness, compression ratio, thermal expansion, water absorption rate, adhesiveness etc. are also as brake
The very important important performance indexes of vehicle piece.
Current brake system is one of most important system of automobile, is that the car deceleration or parking to make to run at high speed design
's.If the system cisco unity malfunction, driver and passenger on vehicle will be injured by traffic accident, safety of life and property
It cannot effectively ensure.
Brake is divided into drum brake and disk brake, and drum brake is the automotive brake of earliest form.By
It is preferable in the heat dissipation effect of disk brake, recently as the continuous improvement of speed, using disk brake automobile increasingly
Increase, especially intermediate car, has been generally used disk brake.
Disk brake main parts size has brake disc, wheel cylinder, caliper, oil pipe etc..Alloy steel for braking discs manufactures simultaneously
It is fixed on wheel, with vehicle wheel rotation.Wheel cylinder is fixed on fixed on the bottom plate of brake.Two brake blocks on caliper
It is attached separately to the both sides of brake disc.The hydraulic action that the piston of wheel cylinder is come by oil pipe conveying pushes brake block to press to brake disc hair
Raw friction catch, it just looks like the plate vised with pliers in rotation that action, which is got up, forces it to stop the same.
When high temperature of the brake block at 300 degree or more, the shear strength of liner and steel back is very low, liner and steel back it is viscous
Knotting strength is a very important index.When once there is flake phenomenon in vehicle travel process, braking system will be caused to lose
It imitates, cause serious consequence.The shear strength and compressive property for how detecting brake block, carry to improve brake flat manufacturing technique
Its high shear strength and compressive property are just particularly important.
Invention content
