Discussed shallowly the automobile braking system is without a doubt, plays is decelerating, role and so on service brake:, in vehicle brake braking systems (popular name, braking) is one of vehicles most important safety devices, and the braking system already became the vehicles driving secure to a certain extent pronoun.Braking system's performance fit and unfit quality mainly may through reliable, stable, the operation strength transmission performance, the system person or household who refuses to move and bargains for unreasonably high compensation when the land is requisitioned for a construction project and brake power and so on several aspects weigh.At present, internationally is familiar with after 100 kilometer/hour vehicles implementation emergency brake the stopping distance determines the car braking system's braking quality.For example, if the stopping distance is 30 meters indicated that this vehicle has had 30 metric system mobilities energy.
Puts briefly, the braking system has the braking force through the friction filler block clamp revolving brake disc or the lining compaction revolving brake drum, during this process as a result of will rub produces the massive friction heats.Therefore, brake action's principle is the travel in automobile energy transformation for the heat energy, thus realizes causes the goal which the automobile decelerates.The braking power which is 250 kilometers/hour heavy passenger vehicles carry on when entire brake needs to one speed to reach as high as 1000 kilowatts, obviously the vehicles to braking system's specification are extremely harsh.
The braking system classification braking system may divide into the service brake: system, in the vehicle braking system, the second braking system and the auxiliary braking system according to the function and so on.The service brake: system's function is causes in the travel the vehicles deceleration, until the parking, is one of driving on the way most frequent use brake functions; The installment which was causes in the vehicle braking system to stop trips the automobile presence which freezes; The second braking system is in the service brake: system expires in the situation guaranteed that the automobile still could realize the deceleration and the parking installment, has listed as one of basic installments in many national this system; The auxiliary braking system uses in slowing down or the stable vehicle speed extra arresting gear.
Question supplement: Braking system's composition tradition's braking system mainly by energizes the installment, the control device, the transmission device and the brake four major components is composed.
The automobile braking system common part includes: Brake drum, brake shoe, brake disc, brake pliers, friction filler block, steel wire, hydraulic pump, vacuum booster, electronic control unit and so on one. Energizes the installment to energize the installment to use in the braking force which has the car braking to need, mainly has the human body mechanical energy, the air compressor and the hydraulic pump three kinds.Because the automobile applies the brake the braking force which needs to be quite big, and is quite frequent, therefore the automobile applies the brake mainly to use the air compressor and the hydraulic pump energizes, the corresponding braking system respectively is the barometric pressure braking system and the hydraulic brake system; The human body mechanical energy mainly uses in the passenger vehicle in the vehicle arresting gear, the driver draws the hand brake lever or steps on presses the foot pedal dive flap, carries on effectively through the steel wire after the wheel applies the brake in the vehicle, prevents the vehicles stop when the landslide or slides moves.Moreover, because the passenger vehicle the inner space is compact, and the brake line is short, therefore often uses the hydraulic brake system; The commercial automobile (for example passenger train, truck, trailer tractor and trailer and so on) the brake line long and carries on the long-distance suburban travel frequently, therefore often uses has the non-divulging pollution and is mad the source supply sufficiently and so on merit barometric pressure braking systems.
Two. The control device control device including has the braking maneuver and control brake effect each kind of part, the brake pedal is the simple one kind of control device.Along with the electronic technology in automobile's massive applications, the brake control installment's computerization degree is also getting higher and higher, then has met each kind of advanced brake function control needs.
