The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, the utility model comprises pneumatics and the control circuit that air compressor (15) is housed, it is characterized in that: increasing on described pneumatics has an emergent air receiver (1), the admission port of emergent air receiver (1) is equipped with check valve (2), check valve (2) is connected with the main air reservoir (3) of pneumatics, the air extractor duct of emergent air receiver (1) divides three branch roads, a branch road is connected with the inlet end of electromagnetic valve D1, the outlet side of electromagnetic valve D1 is connected with back change-over valve (4), back change-over valve (4) is connected with the driving chamber of rear spring compressed air brake cylinder (5), another branch road is connected with the inlet end of electromagnetic valve D3, the outlet side of electromagnetic valve D3 is connected with preceding change-over valve (6), preceding change-over valve (6) is connected with the inlet end of preceding compressed air brake cylinder (7), another branch road is connected with the inlet end of electromagnetic valve D2 through check valve (8) back, the outlet side of electromagnetic valve D2 is connected with releasing change-over valve (9), removes change-over valve (9) and is connected with the brake application by spring chamber of rear spring compressed air brake cylinder (5).
The utility model technical scheme preferably is that low pressure warning switch (10) is housed on the described emergent air receiver (1), and low pressure warning switch (10) is connected with buzzer phone (11); Air-pressure gauge (12) is housed on the described emergent air receiver (1); Described control circuit forms multiloop control circuit in parallel respectively by the low pressure warning switch (13) on the main air reservoir (3), electromagnetic valve D1, D3, rear brake lamp (14) and master cock; Described master cock, is composed in parallel with normally open push button switch f4 and f1f2 interlock combined switch with after pulse switch MCK connects by normally closed switch f3 again; Described control circuit forms the loop by the low pressure warning switch (13) on the main air reservoir (3), electromagnetic valve D2 and f1f2 interlock combined switch.
Principle of work is as follows:
The deposit that (1) is set for this device among Fig. 1 has the compressed-air actuated emergent air receiver above nominal standard pressure, when air compressor (15) normal operation, pressurized air process check valve (2) is to emergent air receiver air feed, because the anxious pressurized air of using of supply has just been laid in the effect of the unidirectional ventilatory function of check valve, emergent air receiver under the state of air supply system normal operation.Though driving vehicle air pressure in the process of braking fluctuates, because the effect of check valve is arranged, the state that the compressed-air actuated pressure of deposit always stably remains on more than the nominal standard air pressure in the emergent air receiver is constant.
1, automatic emergency braking principle of work: when the former brake system of vehicle under-voltage (air pressure is lower than nominal standard air pressure or does not have air pressure fully), low pressure warning switch (13) conducting, simultaneously electric signal is automatically passed to simultaneously elements such as electromagnetic valve D1, D2, D3, rear brake lamp (14) and relay indicating light, make power supply → electric elements → low pressure warning switch → vehicle body → power supply, form multiloop in parallel respectively, be subjected to the control of series connected pulse switch MCK, D1, D3 loop are finished identical four automatically and are disconnected and the process of conducting.During circuit turn-on, each electric elements is worked simultaneously, be that each electromagnetic valve is opened respectively, stoplight stop lamp is bright, and the pressurized air in the emergent air receiver is moved towards three directions simultaneously in brake piping: a direction is removed the self-locking of spring wheel cylinder through electromagnetic valve D2 → releasing change-over valve (9) → brake application by spring air chamber brake application by spring chamber, the trailing wheel left and right sides.Another direction realizes front wheel brake through electromagnetic valve D3 → preceding change-over valve → front-wheel left and right sides compressed air brake cylinder.Another direction realizes the trailing wheel braking through electromagnetic valve D1 → back change-over valve → trailing wheel left and right sides brake application by spring air chamber driving chamber.When circuit disconnected, D1, D3 quit work (state of D2 remains unchanged) simultaneously, two electromagnetic valve exhausts, and the front and back brake is removed, and stoplight stop lamp goes out.Whole automatically emergent brake is automatically finished the automatic braking process that four points are stopped under the effect of automatic control circuit, make the air pressure deficiency have driving vehicle energy pulsation-free stagnation of movement under the effect of this device of potential danger.
Press (promptly turning off) switch f3, automatic emergency braking in front and back is removed.
In the process of automatic emergency, because low pressure alarm (13) conducting is stable by the loop state that low pressure alarm → electromagnetic valve D2 → f2 forms, the state of removing the self-locking of spring wheel cylinder remains unchanged.
The effect of check valve (8) is the function that still can keep removing the self-locking of spring wheel cylinder under the under-voltage situation of emergent air receiver (1) air pressure.Press the f1f2 button switch, the functional rehabilitation of spring wheel cylinder self-locking.
2, hand brake principle of work:
A, under the normal situation of the former brake system air pressure of vehicle, press gang switch f1f2, working simultaneously in two loops of D1, D3 parallel connection, realizes that the manually operated point is stopped or anxious braking (this moment, the stoplight stop lamp of afterbody was also bright).
B, after the braking of the under-voltage generation automatic emergency of the former brake system air pressure of vehicle and removing, press switch f4 as required, D1, D3 open work, realize that the manually operated point stops or anxious braking (rear brake lamp is bright), guarantee vehicle driving safety.
Automatic emergency braking is to finish the braking that several points are stopped automatically, and hand brake is to do as required a little to stop or the braking of the manual operation that urgency is stopped.
