The present invention has the advantages of obtaining extremely great braking friction force and greatly reduced braking distance. The present invention makes it possible to avoid many road accidents.
Description
Affiliated technical field
The present invention is a kind of novel braking brake system that is used for power actuated vehicle, particularly automobile.Its task is when vehicle runs into dangerous situation, in minimum distance (1---5 rice) vehicle ' is extremely checked ', guarantees vehicle, passengers inside the car and the public's life and property safety.Belong to the motor vehicle technology field.
Background technology
Existing motor vehicle brake brake technology is a kind of ' wheel stop technology ', also is a kind of indirect brake technology.Its groundwork pattern and structure are: brake equipment forces the wheel rev down up to stopping operating by friction force, and then by wheel and ground-surface force of sliding friction car retardation is moved forward up to stopping.Its final braking brake effect depends on the size of the force of sliding friction between wheel and the ground.
The significant deficiency of prior art is the drag friction power that can't provide enough.We know, wheel is a circular object, it is that a very narrow line is (in fact because the wheel face and the on-plane surface of wheel with contacting of ground (rail level),, the area of contact of line out of reach all), area of contact is very little, also just very little with ground-surface force of sliding friction, when vehicle advanced with fast speeds, this less friction can't make vehicle stop in short range.
Because power actuated vehicle must rely on wheel just can advance, and mean that it can not obtain to exceed the force of sliding friction of law of physics in the prior art framework, thereby this defective of prior art is an absolute defective.
We analyze with automobile; Since automobile is born, the automobile traffic accident just becomes generally acknowledged first and takes the life killer by force, and the automobile traffic accident of the overwhelming majority all with can't the fast speed short range brake relevant, if can in enough short distance, car be checked, we can say that the overwhelming majority's traffic accident tragedy can be avoided.According to the relevent statistics, the automobile traffic accident accident that this significant deficiency of prior art causes has made whole world tens of millions of people's loss of life, and the wounded is more, and property damage more will be in thousands of millions of.Be thousands of times of the death toll that causes of other any accident.Even considerably beyond many wars and the major natural disasters injures and deaths and loss sum that cause.This is one makes us the startling miserable fact.And dangerous more be: this significant deficiency is eaten the people demon just as one, also all engulfs the tragedy of life in recurrence everyday, and along with the continuous increase of automobile total quantity and improving constantly of speed, its one's bloody mouth is all the more ferocious.
In the face of this tragedy, the improvement of also once trying all possible means of automotive technology circle, as the ABS technology, the tire lines improves, and tire is not full of measures such as gas in use, the also once limited braking quality that improved, however because automobile must use circular wheel, this physical definitely rule has just determined this absolute defective that the change on the fundamental character is arranged in the prior art framework till the ass ascends the ladder.
Therefore, only jump out the not scientific structure framework of existing motor vehicle brake technology, adopt new braking principle, the deceleration and stopping performance of power actuated vehicle could be realized the transition of essence.
The invention technology contents
We know, the essential defect of prior art is that can't to break through circular wheel only may be the physics law of friction barrier that line contacts with ground.Therefore, obtain to surpass the friction force of this law, braking procedure is realized with regard to the impassabitity wheel.
According to this analysis, in the present invention, we have proposed vehicle directly braking and brake principle.
Directly braking as its name suggests, is exactly that vehicle braked is no longer passed through wheel, but realizes by special slipper and ground-surface direct contact.。
The present invention just is based on the brake device for car of this brand-new principle, and its novelty is; Automobile brake and brake no longer realize indirectly by force of sliding friction very little between tire and the ground, but directly realize by the huge force of sliding friction that direct contact produced between slipper and the ground.
The present invention has created the automobile brake plate and has directly contacted with ground, friction, the braking brake pattern that compresses, because slipper is not circular, its working area just can be big arbitrarily, just can be on demand big fully with ground-surface area of contact, the friction force that is obtained also just can be enough big, and high-revolving automobile is checked in minimum distance.
In the present invention, wheel is no longer undertaken the braking brake task, and only is to serve as bearing body weight and proal task.
Set forth the technical pattern and the feature of invention below.
The basic fundamental structure of invention is: vehicle braked propulsive effort device is connecting a cover slipper, and slipper drives pressurized strut by leverage or braking and is fixed on the vehicle body crossbeam, perhaps is fixed on the vehicle bridge of back.Carry out glancing impact, the slipper driven device is pressed to ground, with ground direct contact takes place, and obtains friction force, forces car deceleration to travel forward up to stopping.
Contact process between slipper and the ground adopts is one and is contacted the scalable process that carries out the transition to whole contacts by the part, to realize the adjusting of friction force, thereby realize the adjusting that car speed is controlled, this function is by the drive spindle stroke of propulsive effort device and the corner of lever, and the shape of slipper realizes.
Total maximum frictional force is decided by the thrust that slipper and ground-surface final area of contact and brake provide, and the two all can design adjusting arbitrarily, thereby the present invention friction force that can the provide no maximum of saying so theoretically.On principle,, any high-speed vehicle " can be pegged " in position then and there during the invention process braking brake purely as long as the area of slipper is enough big and the braking thrust is enough big.Certainly in practice, this will be subjected to the restriction of vehicle structure intensity and occupant safety unit protection ability (safety strap etc.).
Below we further set forth the architectural feature of invention in conjunction with the accompanying drawings.
Fig. 1 is the scheme drawing that contrive equipment carries out glancing impact.Fig. 1-the 1st wherein, normal vehicle operation, slipper is unsettled, with the ground no touch.
Fig. 1-2 is the vehicle normal brake application, and an end of slipper contacts with ground, produces a friction force, makes car retardation.
Fig. 1-the 3rd, the vehicle emergency brake, slipper is on the ground compacted, and the huge friction force that the gross area contact produces stops vehicle immediately.
We set forth braking procedure with the compressed air-driven pattern;
Fig. 2 is first kind of exemplary block diagram of the present invention; As seen from the figure, it is made up of slipper 2-1, pole 2-2, pole axle 2-3, pneumatic cylinders 2-4, slipper retracing spring 2-5, pressurized strut piston rod retracing spring 2--6.
The mechanism of this structure is as follows; Chaufeur carries out glancing impact, pressurized air enters pressurized strut, the promotion piston rod moves downward, the resistance that piston rod overcomes spring 2-6 is pressed to ground with slipper, because the pulling force of retracing spring 2-5 is arranged at the front end of slipper, both combineds action just make the rear end of slipper contact with ground earlier, obtain a drag friction power and make car retardation.Chaufeur is regulated compressed-air actuated pressure by the stroke of the plate that touches on the brake, and then the stroke of adjusting piston bar comes control brake plate and ground-surface friction force, reaches required deceleration effect.
During emergency brake, chaufeur is floored braking vane, owing to contact to earth in the rear end of slipper, piston rod promotes the slipper front end and moves downward fast, realizes that slipper contacts with ground-surface gross area, immediately car is checked.
Fig. 3 is second kind of exemplary block diagram of the present invention.
As seen from the figure, second kind of structure is made up of slipper 3-1, preceding pressurized strut 3-2, back pressurized strut 3-3, retracing spring 3-4, compressed air pressure proportional distribution valve 3-5.
The braking procedure of second kind of structure is as follows; When chaufeur carries out common brake snub, compressed-air actuated pressure is lower, and most of pressurized air is flowed to back pressurized strut 3-3 by apportioning valve 3-5, and the piston rod of 3-3 is pressed to ground with the rear end of slipper and contacted with ground, obtain the drag friction power of deceleration usefulness, realize the brake snub of vehicle.
When chaufeur carries out emergency brake, pressurized air reaches anticyclonic pressure, because contacting to earth because of the slipper rear end, the piston rod of back pressurized strut 3--3 arrives down dead position, can not continue motion again, most pressurized air is forced into preceding pressurized strut 3-2, promote piston rod drive slipper front end and move downward, realize slipper and ground-surface total contact, immediately car is checked.
Can also there be the start type of drive of other type to realize that slipper contacts and compresses with ground-surface, all belongs to scope of the present invention.
For some full size vehiclees, engineering truck, elec. vehicle, special vehicle, the braking and drive force device also can be hydraulic gear, gas--liquid joint institution,--gas---liquid joint institution.
Can see that from said process using method of the present invention and prior art are duplicate.
Look vehicle tonnage and design speed, the quantity of pressurized strut can increase to 3,4 or more.And the multichannel that adopts corresponding multichannel pressure proportional distributing valve to carry out brake compression air or hydraulic oil is distributed.The slipper area also can reach vehicle structure intensity and carry out adaptive design according to builder's tonnage and speed, to reach best braking effect.
The advantage of invention
The present invention is the revolutionary breakthrough of of automobile brake brake technology, will bring a brand-new boundary of automotive safety, becomes the patron saint of hundreds of millions life and wealth.
With respect to prior art, the present invention has following main advantages;
1 like never before improves the security level of automobile.Concerning any automobile, after equipment apparatus of the present invention, the braking brake distance will shorten greatly, thereby can avoid most traffic accidents, protect hundreds of millions life and property to escape destruction.
2 thoroughly stop existing automobile brakes frequent sideslip out of control, and danger such as sideslip further reduce accident rate.
Existing automobile brake technology implementation glancing impact is realized jointly by each wheel, is a kind of ' multiple spot is stopped altogether ' structure.Because the braking force of each wheel can not be guaranteed absolute equilibrium; the pavement state at each wheel place also can not be absolute the same; wheel loses preceding guidance force after being prevented rotation in addition; (this promptly studies the origin of ABS technology) thereby regular meeting produce and break away, deviation phenomenon; emergency brake when running at high speed especially; almost will inevitably occur breakking away, deviation phenomenon, cause taking place collision to lose control of one's vehicle, serious accidents such as overturning.And the present invention is because slipper and contact area of ground are very big, there is not this dangerous difficult problem of braking force gap, wheel remains and can freely rotate during brake, automobile just can not lose preceding guidance force, breaking force is arranged in the position after the vehicle mass center of gravity in addition, thereby the braking controllability is splendid, and glancing impact phenomenon to lose control of one's vehicle all can not take place when any speed, and this just can be avoided numerous serious accidents out of control.This point is great especially to the vehicle meaning of running on expressway.
3 thoroughly stop automobile at detour, mountain road, incidental various serious accidents when carrying out braking brake under the bad road conditions such as water route face, ice and snow road, tilted road surface are arranged.
In the existing car accedent is to occur on these bad road conditions greatly, particularly severely injured, the Extra Serious Accident of the dead group of passenger vehicle group is as cliff, the pernicious collision etc. down of rolling, and outside the human element of the major cause of accident except chaufeur, be exactly that the prior art stopping distance is long, and wheel is caused vehicle to lose guidance force and out of control causing by locking during emergency brake.After car equipment apparatus of the present invention, these accidents will be stopped from the technical reason aspect at all.Even, successfully avoid the generation of these serious accidents because the structure of apparatus of the present invention on these abominable road conditions, can obtain huge friction force, the stopping distance of extremely lacking and splendid braking controllability equally.
4 reduce auto cost comprehensively.Though braking effect of the present invention will be far superior to existing technology, but it is much lower more than prior art that its structure, manufacturing technology, material, usage condition, manufacturing, maintenance cost etc. require, can describe with ' rough ' two words, be a kind of cheap and good-quality up-to-date technology that really deserves to be called.Can significantly reduce the manufacturing cost, use cost of automobile, reduction accident cost that more can be unprecedented from time immemorial.For instance, equip automobile of the present invention and just again need not ABS, the sideslip that also need not to brake is safeguarded debugging, and the tire irregular wear replacing of brake generation waits the cost of these work and its generation, damage as for the vehicle of avoiding accident to save, integrated costs such as personal casualty processing are just inestimable especially.
5 is the new foundation for security of raising creation of automotive performance.The automobile of equipment apparatus of the present invention can have broad more room for promotion in each side such as speed, comfort level, handlings, and need not scruple safe restriction, can effectively improve car opertion usefulness.
