Description

Automobile emergency braking device

Technical field

The utility model belongs to the emergency braking apparatus in the auto trade, the brake gear that a kind of automobile is new.

Background technology

Traffic accident is suddenly in tiger.It is reported that the whole nation is annual because of mortality from automobile accidents 100,000 people, reaches 300 people every day, tens00000000 yuan of direct economic losses.At present, what the domestic automobile brake was adopted is that rear wheel brake or front and rear wheel are stopped simultaneously, i.e. the traditional braking mode of the static friction of tire and road surface.This mode is subjected to all multifactor influences, and speed of a motor vehicle height, inertia are big, and road grade, tire are outmoded, the road surface is wet and slippery or the like.Vehicle " stopped " and do not stopped, " system " and do not end, and even traffic accident constantly take place, tragedy is constantly showed.This traditional brake mode significant discomfort is answered the present situation of modern automobile and express highway, automobile brake is the conversion of simple inertia energy just in fact, this switching process be unable to do without " conservation energy " law equally, automobile emergency for high-speed cruising is braked the load that is produced, forcing at any one position of automobile all makes it and can't bear, even may form the disintegration of vehicle, cause bigger disaster.How forming the key that " buffering " become key in energy conversion process, improve brake efficiency, shorten stopping distance, has been to put an automobile colleague big technical barrier in front at home.

Summary of the invention

The contriver has invented a kind of automobile emergency brake device of breaking through traditional mode through thinking deeply for many years and putting into practice.

Technical purpose of the present utility model be to overcome present existence automobile since factor affecting vehicles such as inertia " stop " and do not stop, " system " and more than phenomenon provides a kind of new automobile emergency braking device.

The technical solution of the utility model is: under the prerequisite that does not change present braking device for vehicle, increase the new brake gear of a cover, i.e. and two Metallic rod devices, it is installed in respectively on the hind axle of vehicle.This device partly is made up of the body of rod, head part, spring three.The body of rod is installed on the automobile hind axle, but unfixing dead, but up time or inverse time rotate, one end and spring, automobile brake pull bar join, and the other end is installed the head part of hard alloy, and length is decided on wheel diameter, base length grows radius of wheel 1-5 centimetre, and glancing impact contacts with ground.During driving,, make it depart from wheel and become an acute angle with ground-surface vertical line, the third quadrant angle of unit circle in the mathematics because the automobile brake pull bar withstands rod member one end.Rod member is suspended from the space, does not contact with ground.When the chance emergency situation need brake, decontrol the automobile brake pull bar rapidly, no longer withstand it, according to lever principle, since the pulling force of spring, the quick left-hand revolution of rod member, and head part will contact with ground.Because it is than the long 1-5 of radius of wheel centimetre, certainly will be overhead with the wheel top.Owing to inertia and excessive buffering, rod member can be crossed vertical line, forms the acute angle of the 4th limit in the mathematics, makes head part tightly fasten ground, thereby reaches emergency braking, shortening inertia distance, the purpose of emergency brake.The device of this emergency braking brake is equivalent to except starting conventional brake gear, also increased by two considerable, " upright stopping " vehicle.It is outmoded at tire, the long gradient, and under the wet and slippery condition in road surface, technique effect is more obvious.Certainly, also there is scratch, scrapes a mao ground-surface defective.Heavy motor vehicle emergency braking apparatus (being the Type B device) is a metal rod, and it is made up of the body of rod and head part.The rod member centre portion is connected in the vehicle rear wheel axle, and one end and automobile join, fixing head part above the other end.The content basically identical of its principle of work, emergency braking technical scheme and aforementioned general-utility car.Just when the chance emergency need be braked, automobile by hydrostatic drive to the down-pressed pole body, according to lever principle, car adopts hydrostatic drive (being not to utilize spring), the quick clickwise of rod member, and rod member will contact with ground, and overhead, thereby reach the purpose of emergency braking, brake with wheel top.

The utility model is common car A type device and heavy goods vehicles Type B device respectively, and it is novel, constitutes simply, and strong operability has the excellent development prospect.

The specific embodiment

[0012] this device is made up of the body of rod, head part, spring three parts.Rod member is cast by metal, and head part is made by hard alloy, is fixed on the body of rod one end by screw; Spring is made by high duty metal.When the chance emergency situation need brake, starter gear is decontroled the automobile brake pull bar, according to lever principle rapidly, because the pulling force of spring, the quick left-hand revolution of rod member, head part contacts with ground, and wheel pushes up overhead, because inertia and excessive buffering, rod member is crossed vertical line very soon, tightly fastens ground, thus emergency braking, brake.It more than is common vehicle A type emergency braking apparatus.Heavy goods vehicles Type B device is made up of the body of rod and head part, by hydrostatic drive, and the emergency braking brake.

Claims (2)

1. a general-utility car emergency braking apparatus is a metal rod, it is characterized in that: rod member is made up of the body of rod, spring and head part, wherein partly connect the vehicle rear wheel axle in the middle of the body of rod, the body of rod one end and spring join, fixterm spare above the other end, and the other end and the automobile of spring join.

2. a heavy motor vehicle emergency braking apparatus is a metal rod, it is characterized in that: rod member is made up of the body of rod and head part, wherein partly connects the vehicle rear wheel axle in the middle of the rod member, and rod member one end and automobile join, fixing head part above the other end.
