Description
Technical field
The present invention relates to a kind of brake system of car.
Background technology
At present, known brake system of car major part is by the tire braking, stops and disc brake such as drum, and the tire brake system is divided into five classes:
One, service braking system: be in driving, to use and by foot brake, drg normally is installed on whole tires; Not enough point is: although the ABS anti-lock device is arranged, but tire also can stay drag mark on the road surface when emergency braking, length and the speed of a motor vehicle of drag mark are proportional, the sliding distance under the braking mode in the time of can't shortening braking automobile, especially under the emergency state, although chaufeur has been implemented urgent service brake but still can't force automobile to halt.
Two, emergency brake system: be to prevent after parking that automobile slip from using and by hand brake device, the conventional brake device is installed on the transmission shaft behind change-speed box or the part-time case;
Three, emergency brake system; To use on the automobile of mountain area, by pipeline independently, the parallel drg that is installed on the tire that shares; Not enough point is: remain by tire system and realize, stopping distance is still longer, the out of reach perfect condition.
Four, sure brake system: use when being automobile brake atmospheric pressure deficiency, automobile can't be travelled;
Five, auxiliary braking system: be for the protection service braking system, by the mode of engine exhaust and brake when the long descending of automobile;
Also have now not by tire system emergency brake system, report has for example been arranged on the internet: Mercedes Benz was developed " by tire system emergency brake mode; chassis air bag secondary braking sytem " in 2011 05 month, the said firm has applied to " chassis air bag calibration package " on the concept car, plans to be installed in after 3 years on the S level benz car.This not enough point is:
When although 1 air bag calibration package comes into force, can stop to a certain extent automobile to advance,, automobile is in parastate with the road surface all the time, does not change the locational change of the suffered force of inertia direction of the Automobile Gravity Center and driver and crew on health.
2, friction effect has limitation, this kind technology improves friction force by increasing frictional area, and the size of friction force is not to be directly proportional with area of contact fully, but depend on load on the unit area, popularly be exactly: one of air bag calibration package principle is exactly to use " increase area of contact " to realize that this effect is limited.
3, air bag calibration package, Applicable scope and effect are proportional with the roughness on road surface; Popular, gravel road surface best results at first; Next is new cement concrete, asphalt coating, and effect is general; The road surface effect is relatively poor rainy day again; Last ice-patch surface, snowy road surface have little effect.
According to " State Standard of the People's Republic of China " GB 12676-1999 auto brake system properity and test method, second page, 4.1.4.2 emergency brake must only have in the situation of place inefficacy in service brake, makes vehicle immobilization in a suitable segment distance; Emergency brake must be controollable, should make chaufeur have at least one to hold the braking that just can realize in the situation of bearing circle at its seat.

Technical scheme implementation step of the present invention is:
1, when being in driving states, automobile need to meet an urgent need when stopping;
When 2, chaufeur can't or can not effectively use service brake to allow automobile stop;
3, chaufeur can start the present invention by foot pedal apparatus;
4, can't or can not normally start the present invention when chaufeur, can start the present invention by the linkage that is installed in copilot foot position;
5, when chaufeur, copilot all can't or can not normally start by foot pedal apparatus;
6, namely be positioned at the startup plate in vehicle head section bumper/spoiler the place ahead, when contacting with obstacle, start synchronously the present invention;
7, make front brake assemblies moment and the road surface flexible contact that is positioned at both sides, automotive front vehicle frame below;
8 and the lifting automotive front, make automobile two front-wheels leave the road surface;
9, reach commanding elevation after, the rear brake assemblies that is positioned at automobile tail vehicle frame below contacts with ground;
10 and the lifting automobile tail, make automobile two trailing wheels and surface separation;
11, the powerful force of inertia of automobile this moment all is flexible absorbent by the brake assemblies more than 3;
12 and anti-rebound bar come into force;
13, the system of the present invention rear automobile that comes into force halts.
State procedure figure when car emergency of the present invention braking is housed as shown in Figure 8, Fig. 9 be the brake assembly state change map of correspondence.
Structural attitude of the present invention:
Self contained system, be installed on the automobile chassis frame.
2. simple in structure, pure physical construction.
3. do not contain electronization, electrification, hydrofication.
4. be not related with automobile dynamic system, driving system, service braking system, emergency brake system, steering swivel system etc.
5. bionical crash device in kind is to copy A Cat's Whiskers, and cat never can be hit the principle of wall when catching mouse along wall, and corresponding the present invention is in the structure of the startup plate in automobile head bumper/spoiler the place ahead.
6. use " wooden handcart descending " principle, " desisting from doing something before it is too late " principle and " vector property of newton's second law " principle, after the present invention's startup comes into force, make automobile all tire and surface separation, automobile is low climbing state behind the front height, the center of gravity that namely obtains automobile is mobile after by forward direction, and driver and crew's force of inertia direction moves by being parallel to the shank direction of shield glass to driver and crew.The fan-shaped drg of automobile tail contacts with the road surface; Note: " wooden handcart descending " principle is, fully loaded with cargo wooden handcart, when descending usually all be the driver in front, both hands firmly lift wooden handcart two handlebars to the high-altitude, so that the wooden handcart afterbody contacts with the road surface as far as possible, so just can make wooden handcart low velocity descending, not cause danger; The principle of " desisting from doing something before it is too late " is: the courser speed per hour of galloping at all speed can reach per hour more than 60 kilometers, want to stop rapidly, just must firmly pack up halter rope, head of the horse is lifted in the air, two forehoofs soar liftoff, this moment, the Marko was to be lifted to overhead more than 70 degree, center of gravity is rapidly to the displacement of horse back leg, therefore, is to ride that the people is the easiest to be rolled down at this moment, generally, the Marko is to stop in 5 meters.
7. use " Leonardesque friction one " principle, the size of friction force and the load on the unit area are proportionate; Note: " basic feature of friction it is generally acknowledged that Leonardo da Vinci Leonado da Vinci (1452-1519) is that first proposes the friction basic conception.Under his inspiration, French scientist Amontons carries out the laboratory and has set up law of friction.Subsequently, Coulomb has developed the work of Amontons on the basis of further experiment.It is as follows to have drawn four classical friction experience by these initial research: law one, and friction force is directly proportional with load; Law two, friction coefficient and apparent contact area are irrelevant; Law three, coefficient of static friction is greater than dynamic friction coefficient; Law four, friction coefficient and sliding velocity irrelevant (selecting from: the academic monograph of " tribology principle " Tsing-Hua University, press of Tsing-Hua University, 2002ISBN7-302-05904-7 Wen Shizhu, Huangping work, the 271st page).
