Description

The automobile emergency brake brake equipment

Technical field: a kind of brake device for car, especially a kind of automobile emergency brake brake equipment.

Technical background: automobile needs the braking device guarantee self of good safety and other people trip traffic safety, yet up to this point, both at home and abroad can only to reach 100 kilometers speed per hour hard brake stops distances be more than 20 meters to all best brake device for car, namely is that the travel automobile of 100 kilometers speed per hours plays when stepping on brake and ends this car when stopping and still will slide more than 20 meters and just can stop.Relatively the stopping distance of general common vehicle also needs could stop more than 30 meters.Just because of causing in the world thousands upon thousands automobiles to be smashed with ten hundreds of people, the stopping distance of this twenty or thirty rice sent in vain life and injured disabling.The country of express highway prosperity particularly comprises our China, because the automobile brake distance greatly enhances or the malfunctioning example that causes collision to bump people's accident can be found everywhere.Purpose of the present invention is Creative Design in order to solve or avoid aforementioned braking accident problem.

Technical scheme: embodiment of the present invention has four.Scheme one, instant brake equipment, one to five meter of its stopping distance.Scheme two, be buffer brake device, its stopping distance is five to ten meters.Scheme three, brake equipment at a slow speed, its stopping distance is 10-15 rice.Scheme four, be instant, retarding braking device.Paper scheme one, concrete embodiment is: adopt the roll coil of strip of anti-the granny rag to put a drg, sponge sucks in water or metal bracelet, reel reel motor, reel braking electromagnetism is decontroled with manually decontrol drg and rolling-up machine power operation switch etc. forms by reel, strap, the attached weight of strap for the structure that the cloth roll coil of strip is put a drg.Strap will adopt the Nai Layi volume, robust metal filament, the carbon element silk, the regenerated fiber cloth preferably adopts the flak jackets cloth to make, the concrete cloth roll coil of strip that connects to form is put the step of cylinder and is: at first adopt the high-intensity Metallic rod of having reserved size to become a cylinder through machined into, at cylinder directly to opening a compress trough of belt, with the strap nip roll the long strap of 2-5 rice is pressed in the groove, two and centre are screwed the compress rod, and add two end socket cylinder and further reinforce, bearing carrier ring is loaded onto at the two ends of reel, end at reel connects the scrolling electrical motor, is contained in addition the other end of reel with electrically and manually drum brake connection of a cover.At last, enclose weight at the strap instep and be rolled into a cylinder.Like this, the band reel of anti-a granny rag drg is just calculated to assemble and has been finished.Next step is that the strap drum brake that has assembled is installed on the fixedly suspension bracket at the bottom of large of front top of automobile back wheel, namely fixedly secures directly in front over against trailing wheel.Two trailing wheels of roadlice are equal installs two strap drum brake, and cart requires whole rear wheels, and the wheel that comprises rear towed vehicle is all installed the strap drum brake with equal-specification.Electronic, hand control switch controller is installed at last to the suitable place of operator's compartment, plugged, automobile emergency brake brake system device scheme one assembling that a cover is complete is finished.Scheme two, concrete structure and specification and scheme one are similar, and wherein 5 meters of the Length Ratio scheme one of strap increase by 5 meters, install in addition a buffering speed-up generator additional in the other end of strap drum brake, replace the strap drum brake and use.Its functional purpose is to play the buffering two kinds of functions of braking at a slow speed and generate electricity, and reaches the effect of killing two birds with one stone.The brake mode of scheme three and device thereof are all fully different from one or two schemes.The brake mode of scheme three is the rear plate friction drag brake mode that mop floor, plate mops floor brake equipment by one 2 meters * 1 meter wear-resisting mopping the floor after so-called, the high-abrasive material of available friction coefficient maximum, such as sandpaper plank, the broken plate that is pressed into of metal, used braking vane, hard plastic plate etc. is made.Rear base plate connects a high-intensity stock elbow after adding frame securely, two length points of stock first three minute are passed at the bottom of the beam behind the balance pivot movable span along reaching lower right, operator's compartment driver's seat, then connect manual pull-up in the operator's compartment or the joystick of foot-operated reverse pull-up.Arrive this, the simple emergency braking apparatus declaration of cover assembling is finished.Scheme four, the braking of employing four-wheel pressing plate brake mode.So-called four-wheel pressing plate, namely before and after automobile four wheels above wear-resisting, as can directly to be controlled by a driver friction braking plate is installed, its structure is comprised of upper one group of electromagnet and the high-abrasive material plate of block permanent magnet connection of being connected.During assembling the electromagnet and permanent magnet slipper is loaded on respectively on the fixed mount of each wheel top, connects the control source switch and just can control behind the appropriate location of operator's compartment and braked.Its braking principle is to rely on electromagnet to produce the same sex magnetic line of force permanent magnet braking plate that originally is pulled together is pushed away with wheel contact the generation friction drag, forces parking of automobile.

Principle of work: the principle of work of scheme one is: when the automobile in travelling needs emergency brake to stop, the driver presses electromagnetism take-off the brake button switch or manual take-off the brake joystick, the cloth band reel rotates and unclamps the place ahead that strap directly falls behind wheel on the ground under the pulling of the weight gravity of the attached weight of strap, and the impact that is subjected to the wind that the place ahead blows is close along stretching at the bottom of the rear wheel, just in time just advancing rear wheel touched pendulum forwardly on the ground strap and exhibition roll over, the strap that the result is tightened up blocks wheel and can't rotate and to travel forward and be forced to stop getting off.An of short duration phase buffer is arranged in this process, and namely strap has just been pressed by exhibition and has been tensioned to total length 2-5 rice, and strap discharges during this period of time distance fully, and the inertia potential energy to preshoot of automobile is progressively reducing, and finally is forced to stop getting off.The principle of work of scheme two and scheme one are basic identical, only have a phase buffer different from scheme one, namely stopping distance is than about five meters of scheme one length, and advantage is that braking is mild, lowered the dynamics that the personage pounces on to preshoot on the car, also utilized pulling force to drive the speed-up generator generating and replenish automobile-used.The do not thrust into safety factor of car has reduced again much but shortcoming is safety assurance.The principle of work of scheme three is: when the automobile in travelling needs stopping-down, the driver with hand or pin pull-up the rear base plate brake rod, cause rear base plate to be fallen within on the ground by the lever principle acting in opposition, and be pressed in ground friction drag with producing large-area pressures, cause automobile progressively slowed down by drag effect, stopped and finally drag.Estimate that this stopping distance that mops floor is longer than the stopping distance of scheme one, scheme two, but have than the stopping distance of existing brake device for car shorter effect again.The braking principle of scheme four is the simplest, controls on the top of electromagnetism counter-force disconnector by each wheel and depresses a friction plate as the driver exactly, causes wheel to move and stops.Total assesses, and above-mentioned four kinds of braking schemes and device thereof all effect and the cost than existing automobile brake scheme and device are all advanced cheap.

Social benefit: the present invention has short, cheap, easy and simple to handle, the economical and practical performance of stopping distance, will play very large help to the safety assurance of modern automobile world kingdom.If obtain consistent approval both at home and abroad, and apply, the safety traffic cause of entire society is all had important practical significance.
