Technical field
It wriggles the present invention relates to a kind of for making the friction material of vehicle brake friction sheet more particularly to a kind of can reduce
Friction material of noise and preparation method thereof.
Background technology
Based on the prior art it is found that after using the vehicle launch of automatic transmission, power, which is in, continues output state, row
During sailing, frequent operation brake pedal is needed vehicle to be controlled to stop or advance；When control vehicle is switched to move by halted state
It during state, needs gradually to discharge brake pedal, reduces brake facing to the pressure of brake disc, so as to reduce brake force, work as system
When power is less than the output torque of engine, vehicle moves forward；During this, before vehicle movement, although brake force one
It is directly reducing, but since brake force is greater than or equal to engine output torque, brake disc and friction plate are in static friction shape always
State, when brake force is gradually reduced and is less than the output torque of engine, the Frotteurism meeting saltus step of brake disc and friction plate is
Dynamic friction state, vehicle also move therewith；Due to confficient of static friction and coefficient of kinetic friction difference, after friction coefficient saltus step, can lead
Brake is caused to occur wriggling and generate corresponding wriggling noise, when wriggling noise is lighter, as rubber is sliding on smooth glass
Lasting cluck,coo the sound of movable property life when serious, skid such as two pieces of smooth iron plates and sends out the static abnormal sound of lasting quack；By
It is relatively low in the frequency of wriggling noise, when wriggling noise occurs, steering wheel and vehicle body shake can be induced, at this time sound in driver's cabin
Sound and shake all clearly, seriously affect the driving experience of driver, and particularly in the case of traffic congestion, vehicle needs continuous
Parking, starting, can send out this kind of abnormal sound during each starting, so repeatedly, environment inside car is made an uproar there are serious
Sound pollutes.
