Description
Technical field
The present invention relates to brake block preparation technical field, specially a kind of low noise durable type brake block and its preparation side
Method.
Background technique
Brake block is also brake rubber block, and in the brake system of automobile, brake block is the breaking piece of most critical, all brakes
The quality of effect is all that brake block plays a decisive role, so the brake block for agreeing is the patron saint of people and automobile, brake block
(brake lining) is generally made of steel plate, bonding thermal insulation layer and friction block, and steel plate will come antirust, coating process by coating
The Temperature Distribution of coating process is detected with SMT-4 furnace temperature tracker to guarantee quality, wherein thermal insulation layer is by adiabatic material
Material composition, it is therefore an objective to which heat-insulated, friction block is made of friction material, adhesive, and when brake is compressed on brake disc or brake rim
Friction is generated, to achieve the purpose that vehicle deceleration brakes, due to rubbing action, friction block can gradually be worn, in general
The lower brake pad wear of cost must be faster, and the working principle of brake is mainly to carry out self-friction, utilizes brake block and brake disc
The kinetic energy that vehicle is advanced is converted into the thermal energy of friction, car is stopped by the friction of (drum) and tire and ground, a set of good
Efficient brake system must be able to provide stable, enough, controllable brake weight, and has good hydraulic pressure transfer and dissipate
Thermal energy power to ensure that the power that driver is applied from brake pedal sufficiently effective can pass to master cylinder and each wheel cylinder, and avoids high fever
Caused hydraulic failure and brake decline.
Due to friction catch, the temperature rise for keeping friction secondary is very high, causes the coefficient of friction of traditional semimetal base synthesis brake block
Unstable, noise significantly improves, brake block aging, cracking, abrasion aggravation, reduced service life, due to rubbing action, friction block
It can gradually be worn, the lower brake pad wear of cost in general must be faster, and friction material will replace brake in time after use
Vehicle piece, otherwise steel plate will be contacted directly with brake disc, eventually lost braking effect and damaged brake disc.
