Principle of work
As shown in Figure 1, Figure 2, Figure 3 shows,
A () is when supercharging switch screw rod 36 is closed, supercharging cavity 34 is communicated with air, supercharging cavity 34 does not play pressurization now, and when the force value that regulator 24 sets is 0MPa, the first cavity 1 and the 4th cavity 20 internal detent atmospheric pressure are constant ratio is 1: 2.6;
When supercharging switch screw rod 36 is opened, supercharging cavity 34 is communicated with the first cavity 1, the control gas area of thrust surface of the first cavity 1 inside increase, supercharging cavity 34 plays pressurization, when the force value that regulator 24 sets is 0MPa, the control gas of the first cavity 1 inside and the braking pressure force rate value of the 4th cavity 20 inside can reach 1: 3; Above two kinds of Schema control gas area of thrust surface are greater than antagonistic force braking gas area of thrust surface, and when chaufeur touches on the brake, braking effect is sensitive, and actv. shortens stopping distance.
B () is when supercharging switch screw rod 36 is closed, when the force value that regulator 24 sets is 0.2MPa, when the control gas air inlet pressure of the first cavity 1 inside is less than 0.2MPa, the braking pressure of the 4th cavity 20 inside equals the control gas air inlet pressure in the first cavity 1, and control gas and brake repair room air gate pressure ratio are 1: 1; When now chaufeur touches on the brake, braking effect is soft, reaches unloaded, light truck tire not locking, alleviates wear on tyres, improves chaufeur braking traveling comfort, and improves operation benefits.
When the force value that regulator 24 sets is 0.2MPa, when the control gas intake pressure of the first cavity 1 inside is 0.3MPa, the braking gas air pressure of the 4th cavity 20 inside is 0.48Mpa, and control gas and brake repair room air gate pressure ratio are 1: 1.6; Now suitably increase pressure ratio, vehicle is steadily slowed down.
When the force value that regulator 24 sets is 0.2MPa, when the control gas intake pressure of the first cavity 1 inside is 0.42MPa, the braking pressure power of the 4th cavity 20 inside is 0.8Mpa, and control gas and brake repair room air gate pressure ratio are 1: 1.9; Sealed valve 30 is thoroughly opened, and it is large and constant that brake cylinder obtains pressure ratio, reaches the object of braking rapidly.
When regulator 24 setup pressure value is 0.2MPa, and supercharging switch screw rod 36 open mode downforce ratio can slightly increase, when control gas air inlet pressure is less than 0.2MPa, the control gas of the first cavity 1 inside and the brake repair room air gate pressure ratio of the 4th cavity 20 inside are 1: 1.25; When control gas intake pressure is 0.38MPa, brake repair room air gate pressure is 0.8Mpa, and control gas and brake repair room air gate pressure ratio are 1: 2.1; These two kinds of patterns gently step on braking force softly early stage, and the later stage heavily steps on effectively, is applicable to the braking requirement of most of vehicle, is first-selected braking mode through great many of experiments.
C () is when supercharging switch screw rod 36 is closed, supercharging cavity 34 is communicated with air, supercharging cavity 34 does not play pressurization now, the force value that regulator 24 sets is be the bigger 0.9Mpa ~ 1.0Mpa of 0.8Mpa than the atmospheric pressure value normal air feed air pressure of normal air supply opening 11, the normal open mode of valve 24-6 of regulator 24, control gas and compressed air brake cylinder air gate pressure are constant ratio is 1: 1;
When supercharging switch screw rod 36 is opened, supercharging cavity 34 is communicated with the first cavity 1, control gas area of thrust surface to increase, supercharging cavity 34 plays pressurization, the force value that regulator 24 sets is be the bigger 0.9Mpa ~ 1.0Mpa of 0.8Mpa than the atmospheric pressure value normal air feed air pressure of normal air supply opening 11, the normal open mode of valve 24-6 of regulator 24, the control gas of the first cavity 1 inside and the compressed air brake cylinder air gate pressure ratio of the 4th cavity 20 inside can reach 1: 1.5; When the first Schema control gas area of thrust surface is equal with antagonistic force braking gas area of thrust surface, when chaufeur touches on the brake, braking force is soft.When the second Schema control gas area of thrust surface are slightly larger than antagonistic force braking gas area of thrust surface, when chaufeur touches on the brake, braking force is advanced.
By the combination of regulator 24 and supercharging switch screw rod 36 different mode, can realize controlling gas and brake repair room air gate pressure ratio softly to brake in 1: 1 or 1: 1.5,1: 2.6 or 1: 3 sensitive great dynamics braking, also regulator 24 can suitably be adjusted, make beforehand control gas and brake repair room air gate pressure ratio 1: 1 or 1: 1.5, braking is soft.Later stage control gas and brake repair room air gate pressure ratio are 1: 1.9 or 1: 2.1, and braking is strong.The pattern that this device is adjusted to this vehicle applicable and driving habit is installed, various automobile different braking power demand can be met and use, make it brake steadily, effectively, realize the variety of single brake equipment brake percentage, improve the comformability of brake equipment.
Utilize technical scheme described in the utility model, or those skilled in the art being under the inspiration of technical solutions of the utility model, designing similar technical scheme, and reach above-mentioned technique effect, is all fall into protection domain of the present utility model.
