Accompanying drawing explanation
The structural representation of Fig. 1 present invention.
Detailed description of the invention
Shown in Fig. 1, relate to the experimental provision of a kind of simulated automotive Pneumatic braking system, including electric air pump 4, its outfan with
Air tank 5 connects, and the outfan of described air tank 5 is connected with brake control valve 7；First output of described brake control valve 7
End is connected with brake chamber 14 before left front brake chamber 9 and the right side respectively by front pipeline, the outfan of described left front brake chamber 9
Being connected with the near front wheel 11 by left front brake pushrod 10, before the described right side, the outfan of brake chamber 14 is by right front brake pushrod
13 are connected with off-front wheel 12；Second outfan of described brake control valve 7 by rear pipeline respectively with left back brake chamber 18 and
Behind the right side, brake chamber 15 connects, and the outfan of described left back brake chamber 18 is by left back brake pushrod 19 with left rear wheel 20 even
Connecing, behind the described right side, the outfan of brake chamber 15 is connected with off hind wheel 17 by brake pushrod 16 behind the right side.Wherein, gas is also included
Pressure alarm device, this pressure warner includes the too low alarm switch of air pressure 3 being arranged at described air tank 5 one end, described gas
The positive terminal pressing through low alarm switch 3 passes sequentially through parking brake switch 24, ignition switch 23 is connected with accumulator 22, its negative pole end
It is connected with alarming horn 25；The control end of described brake control valve 7 is connected with brake pedal 1 by brake pushrod 2.
Wherein, the outfan of described air tank 5 is provided with air tank air gauge 6.
Wherein, described front pipeline 71 is provided with front pipeline air gauge 8, described rear pipeline 72 is provided with rear pipeline air gauge
21。
During use, being integrated on a platform by each parts of too low to Pneumatic braking system and air pressure alarm device, electric air pump is
Alternating Current Power Supply, individually controlling, four wheels are driven by alternating current generator, are also individually to control, and are provided with air pressure on each pipeline
Table, for showing the change of respective line air pressure；The too low alarm switch of air pressure is arranged on air tank, is less than at air tank air pressure
Switch Guan Bi during normal value；Parking brake switch is arranged on below parking brake, unclamps this switch of parking brake Guan Bi.
First open electric air pump, make air tank air pressure reach normal operating air pressure；Open wheel drive motors, vehicle wheel rotation.No
Stepping on brake pedal, air tank air gauge display gas receiver air pressure, pipeline air gauge air pressure is shown as 0.Step on brake pedal, considerable
