Referring to the circuit diagram of Fig. 7, if chaufeur selects new hand's pattern, gas safety guard 100 of the present utility model, in practical operation, mainly comprises following two kinds of situations:
The first situation, chaufeur jams on Das Gaspedal 2, and when the power that jams on suffered by Das Gaspedal 2 reaches or exceedes the maximum pressure threshold values of throttle, then throttle sensor 4 forwards the limit to and can not rotate again.Slip shell 21 overcomes the predetermincd tension of driver plate spring 27 and is rotated further, make the circuit of throttle Magnetic sucking switch jack-up projection 19 jack-up throttle magnetic normal open switch 9 conducting throttle magnetic coil 24, thus slip shell 21 moves towards the direction of the Das Gaspedal pipe link 251 of throttle axle 25 under the magnetic action of throttle magnetic coil 24.The movement of slip shell 21 makes driver plate 18 and throttle sensor 4 depart from, and throttle sensor 4 resets under the effect of throttle sensor pull back spring 17, makes throttle be back to idle position; Meanwhile, moving axially of slip shell 21 makes slip shell lock slots 15 and the contraposition of slip shell lock pin 10, and slip shell lock pin 10 snaps in slip shell lock slots 15 under the effect of lock pin spring 11, axially to be locked by slip shell 21.Meanwhile, throttle magnetic normally closed switch ejector pin 12 leaves throttle magnetic normally closed switch 13, and throttle magnetic circuit is disconnected.Meanwhile, vacuum booster Magnetic sucking switch 8 is opened by the vacuum booster Magnetic sucking switch flange 22 of slip shell 21, to connect the magnetic circuit of magnetic relay 5.
After the circuit connecting magnetic relay 5, vacuum servo magnetic coil 35 produces magnetic force, and attract vacuum booster magnetic purlin iron 36 to move towards the direction of vacuum servo magnetic coil 35, thus drive vacuum valve push rod 37 to promote vacuum valve 41 to move towards the direction of housing 60, then vacuum valve 41 cuts out, and ante-chamber 28 and back cavity 29 are separated.Vacuum valve push rod 37 overcomes the elastic force of vacuum valve spring 40, and promote atmos-valve 42 and continue to move towards the direction of housing 60, compressed atmosphere spring 31, atmos-valve 42 is opened.Extraneous air flows into back cavity 29 by vacuum valve push rod air slot 43, thus mineralization pressure is poor between back cavity 29 and ante-chamber 28, then vacuum diaphragm 34 is pressed and direction towards ante-chamber 28 is moved.Vacuum diaphragm 34 is with dynamicthrust steel disc 33 to move together, and thrust steel disc 33 drives valving shell 39 to move integrally.Master cylinder push rod 30 moves along with valving shell 39, and promotes brake master cylinder piston, makes braking automobile.Because vacuum booster magnetic coil 35 is mounted in valving shell 39, be along with valving shell 39 together moves during its work, the pressure of back cavity 29 is final equal with external atmospheric pressure, so its brake is carried out with maximum braking force.
It should be noted that, before Das Gaspedal 2 is not totally released, slip shell 21 can not reset by the locking of slip shell lock pin 10, and accordingly, vacuum servo Magnetic sucking switch 8 is still in on-state, then automobile remains on braking state always.
The second situation, chaufeur is totally released Das Gaspedal 2.Because the slip shell lock slots 15 on slip shell 21 is inclined-planes, the inclined-plane of slip shell lock slots 15 is equal with the outside face of slip shell 21, slip shell lock pin 10 loses the constraint to slip shell 21, slip shell 21 resets under the spring-force driven dual of slip shell pull back spring 23, vacuum booster Magnetic sucking switch jack-up flange 22 leaves vacuum booster switch 8, namely vacuum booster Magnetic sucking switch 8 disconnects, cut off vacuum booster magnetic coil 35 circuit, and vacuum booster magnetic coil 35 quits work and loses magnetic force.Atmos-valve 42 supports in the bottom of vacuum valve 41 under the application force of spring, air valve 31, and atmos-valve 42 cuts out.Spring, air valve 31 overcomes the elastic force of vacuum valve spring 40, make atmos-valve 42 promote vacuum valve 41 and move towards the direction away from housing 60, and vacuum valve 41 is opened.Under the application force of pull back spring 32, by thrust steel disc 33, master cylinder push rod 30, vacuum diaphragm 34, valving shell 39 are promoted towards the direction away from housing 60, then releasing of braking.Ante-chamber 28 communicates with back cavity 29, until pressure is equal and again return back to initial state of equilibrium.
Further, the gas safety guard 100 that the utility model provides also is provided with test switch 46 and indicator lamp 48 (as shown in Figure 7).Described test switch 46 and indicator lamp 48 are arranged on the central control panel in operator's compartment, and test switch 46 is for testing automobile throttle safety guard 100 whether normal operation.During test, driving model select switch 1 is set as new hand's pattern.Without the need to real extension when travelling; but original place start the engine; more than middle throttle; press test switch 46, then driving engine cuts out throttle automatically, and rotating speed returns back to idling mode; and indicator lamp 48 lights; trigger vacuum servo magnetic coil 35 and produce magnetic force, and attract vacuum booster magnetic purlin iron 36, thus whether simulation testing automobile throttle safety guard 100 normally can work.
Further, if automobile is instructional car, then test switch 46 can be arranged on trainer side, uses as trainer's emergency brake button.
Further, in travelling for preventing vehicle, mis-accelerator pressing causes car rear-end when brake, is also provided with stoplight stop lamp relay 47.When gas safety guard 100 emergency brake is braked, by stoplight stop lamp relay 47 brakes on lamp 49, warning rear car is taken care.
As can be seen here; the gas safety guard 100 that the utility model proposes; when the power that jams on that Das Gaspedal 2 is subject to reaches maximum pressure value; by coordinating of throttle linkage switch 3 and vacuum booster 6; vacuum valve 41 in vacuum booster 6 cuts out; atmos-valve 42 is opened, and drives master cylinder push rod 30 to promote brake master cylinder piston, makes braking automobile.Effectively ensure that traffic safety, avoid the generation of car accedent, protect the safety of life and property of chaufeur.
