The purpose of this utility model is to provide a kind of full-axle automatic compensation emergency brake device for automobile, vehicle is occurred under any fault in former brake system, emergency brake can provide the preceding sedan-chair and the back axle (or many bridges) of automobile synchronously automatically, and the braking force of its car load is remained unchanged.
The technical measures that reach the utility model above-mentioned purpose and take are as described below: full-axle automatic compensation emergency brake device for automobile is mainly done tube, back air storage by the air pump of former car brake system, the wet tube of air storage, preceding air storage and is done tube (or independently tube is done in the emergency brake air storage), master brake cylinder, brake piping etc. and form, and also comprises two-position three-way valve, propons guard valve, the emergent throttle compensating valve of foot control, quick start valve, check valve, the two diaphragm emergency brake brake repair rooms of two valve, three valve spring energy-storage brake repair rooms, Parking handle and associated pipe.Wherein connect a quick start valve, a check valve from the pipeline between air pump to the three valve spring energy-storage brake repair room; A manual Parking valve and the emergent throttle compensating valve of foot control; The emergent throttle compensating valve of foot control is to connecting an equalizing pipe between the former compressed air brake cylinder ante-chamber; The emergent throttle compensating valve of foot control is by pull bar and brake pedal interlock; Manual Parking valve is connected with the independent Parking handle that is provided with by backguy; Do in the back air storage between the pipeline of tube and above-mentioned check valve back and be connected another check valve.In addition, can only connect a quick start valve and a check valve the pipeline between the braking of air pump to three valve spring energy-storage.The front diaphragm air chamber that replaces the two diaphragm emergency brake chambers of two valves of former propons brake cylinder is connected with master brake cylinder by intrinsic pipeline.The rear film air chamber of the two diaphragm emergency brake chambers of two valves is connected with the pipeline of back axle brake repair room with pipeline, and diaphragm chamber is connected with the pipeline of back axle brake repair room with pipeline thereafter.Have when meeting an urgent need air tank separately and connect the propons guard valve with pipeline, propons guard valve pull bar and brake pedal interlock.
Practice shows, the utlity model has advantages such as simple in structure, dependable performance, cost be low, safe, practical.
A present embodiment shown in conjunction with the accompanying drawings further specifies the action principle of its layout to the utility model.
Fig. 1 represents the layout scheme drawing of the utility model full-axle automatic compensation emergency brake device for automobile.
As seen from the figure, the utility model mainly by the wet tube 6 of air pump 1, quick start valve 2, two-position three-way valve 3,4, check valve 11,12 etc., air storage, preceding air storage do tube 8, the back air storage is done tube 7, master brake cylinder 9, three valve spring energy-storage brake repair rooms 5, the two diaphragm brake repair rooms 18 of two valve and equalizing pipe 13, foot brake pedal 14, Parking handle 15, rapid release valve 16, tracheae 17,19 and is formed.Also have emergent air tank 20 and propons guard valve 21.
Behind the engine starting, the pressurized air of air pump 1 is directly imported spring cavity compression brute spring through quick start valve 2, check valve 12, two-position three-way valve 3,4, because of the spring cavity volume very little, so can in less than 10 seconds time, spring be compressed rapidly, brake off is realized the purpose that fast starting travels.Obvious this purpose only connects a quick start valve 2 in above-mentioned pipeline and a check valve 12 also can be realized.The passage that leads to wet air tank in the quick start valve 2 is to be in closed condition this moment, and after the spring cavity inner air pressure rose to more than the safe atmospheric pressure value rapidly, passage was opened voluntarily, and the pressurized air of air pump 1 just flows to the wet tube 6 of air storage, enters normal air feed state.This conversion can be implemented repeatedly automatically.This conversion also can change the quick start valve on manually operated valve and realize.When vehicle needs Parking, only need to handle Parking handle 15, make the passage bc of manual Parking valve open, simultaneously closing passage a, pressurized air in the three valve spring energy-storage brake repair rooms 5 realizes parking function through the passage ba of the emergent throttle compensating valve 4 of foot control, the passage bc exhaust to atmosphere of manual Parking valve.The effect of check valve 11,12 is to stop backflow under-voltage in tube 7 is done in the back air storage, spring energy-storage chamber 5 compressed airs when decompression is zero until air pressure, avoids causing " heat fade " of braking force because of the backflow decompression causes the continuous friction brake drum of brake strap.Pressurized airs in this moments three valve spring energy-storage brake repair rooms 5 need be operated foot control emergency brake valve 4, open channel bc or manual Parking valve 3 and be come open channel bc to be discharged, thereby implement to slow down stagnation of movement or Parking.
The emergent throttle compensating valve 4 of foot control is by pull bar and brake pedal 14 interlocks, by equalizing pipe 13 the porthole C of the emergent throttle compensating valve 4 of foot control is communicated with former compressed air brake cylinder (three valve spring energy-storage brake repair room ante-chambers) 10, when brake pedal 14 comes downwards to certain stroke, pressurized air in the spring energy-storage brake repair room 5 is through the passage bc of the emergent throttle compensating valve 4 of foot control, equalizing pipe 13 communicates with the former compressed air brake cylinder 10 interior pressurized airs that provided by master brake cylinder 9, as long as hindering for some reason, the air pressure in the former compressed air brake cylinder 10 (lost efficacy as master cylinder, pipe breakage, the brake repair room epithelium breaks or the like) when causing deficiency or being zero, the air pressure of three valve spring energy-storage brake repair rooms 5 will be worked thereupon decompression.The moving wheel cylinder 10 of former braking because of decompression cause the braking force loss what, brake application by spring chamber 5 just can synchroballistic what, the braking force of output is remained unchanged, realized intelligentized full automaticity compensation.Eliminated the above-mentioned required reaction time more than 2 seconds of chaufeur.As long as the air pressures in the former compressed air brake cylinder 10 reach more than the safety value of regulation, though by equalizing pipe 13 conductings above-mentioned air chamber,, because of the existence of no difference of pressure, just can not work in brake application by spring chamber 5, but in the monitoring state at any time.Because the air feed of spring energy-storage brake repair room 5 is provided by independent loop, therefore above-mentioned self-compensating process will be provided repeatedly with the reciprocating action of brake pedal 14, thereby realized that vehicle is under the situation of tape jam, can provide braking as usual and emergent safely travelling, must driver's additional operations.
The propons dress two diaphragm brake repair rooms 18 of two valves, its front diaphragm E and air chamber are exactly former car diaphragm and air chamber, are exactly former car design-calculated function by pipeline 17 connection master brake cylinder 9, its function.Rear film F in the two diaphragm brake repair rooms 18 of two valves are close to inwall behind front diaphragm E and the wheel cylinder, and dimensioned area and front diaphragm E are equal to, and are connected with the back pipeline of compressed air brake cylinder 10 by pipeline 19.When the air inlet of front diaphragm E air chamber (implement propons braking), atmospheric pressure promotes front diaphragm E motion work done, simultaneously rear film F is pushed backward the back inwall that is attached to the two diaphragm brake repair rooms 18 of two valves.The rear film F of the two diaphragm brake repair rooms 18 of two valves is during at the brake pedal 14 descending certain distances of interlock and to its air feed, because front and back pressure equates that so do not move, no stroke does not provide emergency brake.But when front diaphragm E breaks or supply air line breaks, the faults such as ante-chamber inefficacy of master brake cylinder 9 cause under-voltage, decompression when being zero, rear film F lack of equilibrium pressure and random action, self-conpensating usefulness-identical with the intelligent automatic compensatory michanism of above-mentioned back axle spring energy-storage braking is provided, and effect is the same.
Vehicle with independent emergent air tank 20, the supply air line of the rear film F air chamber of the two diaphragm brake repair rooms 18 of two valves be pipeline as shown in phantom in FIG. then, and connects propons guard valve 21, links in foot brake pedal 14, and the usefulness of realization is constant.
Because the payload space of diaphragm F and diaphragm E equates, so the braking force that automatic compensation provides equals the braking force that diaphragm E provides under the intact situation all the time.The design of the power of energy stroage springs is identical therewith in the back axle spring energy-storage brake repair room 5, and therefore, the utility model device hinders for some reason and when losing efficacy, the braking force of car load remained stationary when arbitrary loop of former braking or two loops with regard to having realized.Because the emergency brake of the utility model device is the former car master brake cylinder in brake pedal of linking, so provide the actuating time of emergency brake just can be synchronous with former braking.The steerability of braking force is also identical.
In sum, the utility model emergency brake provide be automatically, with catastrophic failure be synchronous, do not need chaufeur to react the time, must not go operation yet, still remove to step on brake pedal according to the needs of deceleration, stagnation of movement or emergency brake as cruising with a hand.The utility model is intelligentized full automaticity compensation way to full-bridge automated provisioning emergency brake, and fault causes braking force what have lost, and just compensation how much, and braking force is remained stationary all the time.The utility model can ensure that the vehicle safety of tape jam is emergent and travel that in emergent the travelling, the driver only need step on pedal usually, just can normally provide slow and brake or emergency braking.It is zero vehicle left and right sides fast starting safety traffic in 10 seconds behind engine starting that the utility model can make air storage pressure.
The emergency brake that the utility model provides has overcome that the prior art emergency brake only provides back axle and defective that the propons that turns to function can't be provided makes running safety be able to very big lifting.
