Description
The present invention relates to automobile braking device, particularly a kind of directly dropping on the road before wheel, the Pneumatic automobile quick safety brake of a brake action.And only when emergency braking or sleety weather road cunning meet emergency situation, the emergency braking safety device that just works.
Used automobile braking device is divided into pneumatic and surges two kinds, relies on brake facing to withstand the braking hub, and wheel can not be rotated, and realizes the emergency braking brake.Its brake action is not enough because the inertia of automobile is big, so the vehicle of running at high speed is when something unexpected happened,, also can not at once car be checked even brake driver is very timely, sometimes after depressing brake pedal, automobile still will be gone out tens meters forward and just can stop.A large amount of traffic accidents just occurs within these tens meters, causes the car crash tragedy.Therefore, the brake of automotive safety and actv. has become one of world today's field of traffic sixty-four dollar question.In recent years, some new automobile braking devices had appearred in patent documentation.For example, the patent No. is CN85109714A, and name is called the patent of invention of the brake circuit that uses in the power actuated vehicle, and it mainly is to have increased the braking reliability.When one of main pipe was damaged or break down, the drg on still can forward trailing wheel made the braking of vehicle safety ground.It is not improved from the physical construction aspect of brake equipment, so its brake action does not have the raising of essence.Again for example, the patent No. is CN87215363U, name is called the automobile rainy day and helps the brake utility model patent, be that a wedge shape slipper that links to each other with the piston of cylinder is arranged in the automobile back wheel front, piston inserts the wedge shape slipper rapidly in the gap of trailing wheel and ground intersecting during brake, thereby automobile is checked fast.Though the braking action of this patent increases, its cylinder and connecting rod are mounted on the automotive frame, under the impact effect of wheel, can make the crossbeam stress deformation, even cause the accident.In case and wedge pushed down by wheel, piston rod just is difficult to regain and goes, must reversing could return, not only inconvenience but also be unfavorable for safety.Again for example, patent No. 89213108X, name is called the utility model patent of throwing type emergency braking apparatus, form by hoisting mechanism, belt and triangular-notch weir wood, when emergency brake, the triangular-notch weir wood that this device will tie up to belt one end is thrown the front lower place in wheel, and the automobile of running at high speed is checked.The brake action of this patent is also stronger, is difficult to guarantee by the ideal position of throwing before wheel but its shortcoming is a triangular-notch weir wood, and can presses triangular-notch weir wood to wheel when the speed of a motor vehicle is too fast, belt is broken, cause that vehicle body beats suddenly, this installs the moving operation of basic armrest, and is convenient inadequately.Above-mentioned in addition three patents all do not have the work monitored control system, and back two patents reaction is slower, and this all is the factor that influence is applied.
Purpose of the present invention just is the shortcoming and defect part at prior art, provide a kind of brake action very strong, and the chock landing rapidly and accurately, and degree of automation is higher, and have the advanced more automobile emergency brake of work monitored control system.
The objective of the invention is to realize by following technical proposals.
This device locks mechanisms by three cover magnet-switch mechanisms, three cover air chamber assemblies, two triangle drgs, two cover drgs, and brake control valve, gas circuit pipeline, crank link mechanism and working status monitoring system are formed.
Wherein a cover magnet-switch mechanism joins together by its shaft clevis and torque arm and braking system valve, and all is installed on the vehicle frame.Other two cover magnet-switch mechanisms lock mechanism by shaft clevis and lever with drg and join together, are installed in respectively on the front upper place floor extension of two rear wheels.
Wherein a cover air chamber assembly links to each other with the rocking arm of crank link mechanism by its shaft clevis, and is fixedly mounted on the automobile axle by support.Two triangle drgs about other two cover air chamber assemblies are respectively applied for, its housing is installed on the A-frame of drg, and its shaft clevis links to each other with drg fore-set middle part.
The gas circuit pipeline links to each other the compressed air outlet of drg control cock with the admission port of each air chamber assembly.
Crank link mechanism holds axle, rocking bar, crank throw, crank throw bearing, positive stop, mechanical arm, mechanical adjustment arm, elastic joint and reset tension spring by rocking arm, connecting rod, connecting rod and forms.Its connecting rod bearing is installed on the back axle, and the crank throw bearing is installed on the floor extension, and positive stop also is installed on the floor extension, is used for limiting the pivot angle of crank throw.The upper end of its mechanical arm and mechanical adjustment arm all is connected with the crank throw bearing, and the lower end all is connected with the triangle drg.
The triangle drg is made up of air chamber assembly, A-frame, fore-set, automatically regulating power-assisted plate, fore-set connecting pin, power-assisted plate pivot pin, brake support frame base, drag friction piece and retracted for clearance extension spring.Under the cruising situation, two triangle drgs all are in contraction state, and are locked in the front upper place of two trailing wheels by lockout mechanism.
Above-mentioned magnet-switch mechanism is made up of cover plate, main and sub-coil, electromagnetic core, pull back spring, shaft clevis and normally closed button switch.
The lockout mechanism of above-mentioned triangle drg is by lever, lever fulcrum, locking bolt, locking cover, pull back spring, and bearing and upper limit position block composition.
Above-mentioned working status monitoring system is by 1 three gear on-off, three button switchs open in usual, and 2 normally closed button switchs, 3 light-emitting diodes are formed.Three gear on-offs wherein and three light-emitting diodes are installed in the operator's compartment.
The working process of this device is: when chaufeur finds that emergency situation needs sudden stop, immediately brake pedal is stepped on earth, the power supply of two cover magnet-switch mechanisms is switched on simultaneously.Under the effect of electromagnetic force, the locking bolt of lockout mechanism is the indentation lock bolt sleeve immediately, and the triangle drg is released.The pressurized air of brake control valve is inflated to the work air chamber of each air chamber assembly immediately by the gas circuit pipeline.Under the push rod of air chamber assembly promotes, crank link mechanism pulling triangle drg falls immediately, the fore-set of drg is automatically regulating power-assisted plate jack-up certain angle at this moment, drg just in time falls within the angle of rear wheel the place ahead and ground formation, leans on the bigger friction drag in drag friction piece and ground that car is checked fast.When automobile reran, chaufeur was decontroled brake pedal, and the power supply of two cover magnet-switch mechanisms is disconnected simultaneously.Lose electromagnetic push, the pressurized air of control of braking valve insertion and each air chamber assembly work air chamber is disposed to atmosphere from the deflation hole of brake control valve immediately.The fore-set of triangle drg and automatically regulating power-assisted plate are swung forward and are resetted, and the mechanical swing arm of crank link mechanism and mechanical adjustment swing arm meanwhile upwards packed up the triangle drg and to be resetted under the retracing spring tension, and locked by lockout mechanism.The light-emitting diode of monitored control system is bright or go out in this process, and whether chaufeur this brake gear work as can be known is normal.
The present invention and prior art contrast, its major advantage is: structure is more reasonable, and brake action is stronger, and braking distance is shorter, and it is reliable to be swift in motion, and degree of automation is higher, owing to have working status monitoring system, more convenient to operate; It need not change the design of automobile original structure, and most parts all are commercially available automobile specified accessories, and maintain and replace is very convenient, and with low cost, and therefore numerous drivers are willing to use very much.
