Quality to braking effect is played a decisive role, and brake block is typically made up of steel plate, bonding thermal insulation layer and brake pad.Brake pad by
Friction material and adhesive composition, brake pad is compressed on brake disc or brake rim during brake produces friction with it, so as to reach
To the purpose for making vehicle deceleration brake, it is seen then that brake pad determines performance of the brake block under high-speed and high-temperature braking condition, friction material
Material is brake block part critically important during manufacturing process and use.
The operation principle of brake, which is mainly, carrys out self-friction, utilizes rubbing for brake block and brake disc (drum) and tire and ground
Wipe, the kinetic energy that vehicle is advanced is converted into the heat energy after friction, car is stopped.A set of good efficient brake system must
Stable, enough, controllable brake weight be able to must be provided, and with good hydraulic pressure transfer and heat-sinking capability, to ensure to drive
The power that people is applied from brake pedal sufficiently effective can pass to master cylinder and each wheel cylinder, it is to avoid hydraulic failure caused by hyperpyrexia and stop
Car fails.
Conventional brake block is divided into：1st, asbestos type, because asbestos fibre has high intensity and resistant to elevated temperatures feature, therefore it is full
The requirement of sufficient brake block and clutch disk, while there is the tensile energy of fiber and the hardness of advanced metal material and wear-resisting
Property；2nd, semipermanent mold, it is main excellent mainly using coarse steel wool as fiber and the big mixture of important coefficient of friction is reinforced
Point is to adapt to normal work at relatively high temperatures, but noise is too big, and larger to the wear rate of brake disc；3rd, without stone
Cotton organic type, mainly with glass fibre, aromatic polyester fiber and other fibers as reinforcement material, its performance mainly takes
Certainly in the type and other mixtures of fiber, advantage is the characteristics of nothing falls ash fouling, noise is small, has the disadvantage wearability and heat resistanceheat resistant energy
Power is not strong.
