DEVICE BY CHAIN REACTION FOR EMERGENCY BRAKING IN VEHICLES

Title:

DEVICE BY CHAIN REACTION FOR EMERGENCY BRAKING IN VEHICLES

Document Type and Number:

WIPO Patent Application WO/2003/045749

Kind Code:

A1

Abstract:

This Device by chain reaction for emergency braking in vehicles is made up one or more supports (G) containing a variable amount of openings (B). These openings are settled with an adjustable angle. The openings are loaded with explosives that are able to generate high quantities of non inflammable gas. When the explosives are made to explode rapidly and in sequence they generate a force of reaction in the opposite direction of the moving vehicle thus reducing dramatically the stopping space. The device does not substitute the usual braking system, but it is complementary to it and it integrates to it in emergency situations where it is used.

CLAIMS

1.

1) This chain reaction device for emergency stopping/braking in vehicles both on the road and rail (especially for high speed trains) is a system which help to minimize the length of space needed to stop a car, thanks to an external force of reaction, which adds up to help the effects of friction (especially relative to those whit discslining and others in function whit the atmospheric conditions, those relative to wheel/road wheel/rail) type which in function to the structure mass of the vehicle determine the distance of stopping space.

2.	The chainreaction device for emergency braking can be used on any type of car independent of the weather conditions.

3.	The device at point (1) only to be used when completely necessary, helps the vehicle when braking, reducing the length of space needed to stopby a length in base of the amount and type of explosive or propellant used.

4.	The device at point (1) hasn't a limited number of explosive loads that can be installedy can be regulatedwhich would therefore not cause an excessive or violent thrustwhich could otherwise damage the structure of the vehicle or damage the goods.

5.	The device at point (1) can be reused and parts changed, or rechargedas in diagram (1/5), (which forces the two rotary e (G) A propellant, also interchangeable.

6.	The device at point (1) has adjustable/rotary openings (B) controlled by hydraulic piston (or the other) which the central command and brake circuit and the jet guide (G, Fig. 1/5).

7.	The device at point (1) can be produced using various dimensions and materials of different qualities (pr. e. g. solution Fig. 3/5) to adapt to any type of vehicle, obviously using the same basic device method.

8.

The device at point (1) is set into a: A) automatically when the brakes are heavily pressed down using forced and prolonged action. After receiving these impulses from the central brake system. the device will then act accordingly (P, Fig. 5t5). B) manuallyor by order of the driverwhen the brakes are heavily pressed or by a sensor button which would be positioned on the steering wheel or an appropriate place. (depending on type of vehicle) (M, Fig. 5/5).

9.	The device at point (1) to propose the gasused to generate the refraining force, any type of propellant of mixture of propellant cam be usedon one condition that they do not emit dangerous flames or not neutralised by other devices.

Description:

DEVICE BY CHAIN REACTION FOR EMERGENCY BRAKING IN VEHICLES This Device by chain reaction for emergency braking in vehicles is made up a support containing a variable amount of openings that are loaded with explosives that generate highly quantities of non inflammable gas, and when made to explode in pair-very quickly and in sequence, generate a force of reaction in the opposite direction of the moving car-reducing the stopping space.

The device does not substitute the actual braking system, but it is complementary to it.

The simultaneity action of the two parallel jets-placed on the main brake barycentre, at an angle of incidence with automatic registering, protects from any occurrence of unbalancing.

In fact, moving the two jets and inclining them-varies the result of the type of force in each of them, governing the vehicle while it brakes- guarding it from any eventual swerve.

The dosage of charges are dimensioned in accordance of their number, the type of explosive, the mass and the structure of the vehicle.

PRESENT SITUATION

During the phase of braking, a vehicle covers a certain length of space (more or less controlled) this depends on the speed, the surface friction of the tyres, the friction coefficient and the braking system.

The Italian rood safety code-art. 186-has fixed limits for braking space need: S = V2/130 for cars-corresponds to braking of 4 m/sec2 S = V2/100 for road trains-corresponds to braking of 5 m/sec2 In the braking space needed could be reduced by even one metre less, it could at time save human lives, industries have always played a responsible part in research to gain these results. For example : a device called "emergency stop"which is present on the latest generation vehicles, takes place during an abrupt stop action-a total and prolonged pedal brake which uses the maximum force of braking of the vehicle-until the limit of it sliding or swerving.

The device for emergency stopping doesn't substitute the actual braking system ant integrates with it-like an external help-working by the thrust generated, by reaction of the jets of fluid.

The reaction device-to operate safely-is necessary to be equipped whit : distance sensor (S, Fig 4/5); tear indicators, use of safety belts; eventually safety barrier (P, Fig. 4/5) ; a) At the two end extremes of the supporting base are placed two sensor (S) which relate and compare the distance from the ground, which in the absence of thus regulated distance, intervene 0 with-0 the switches (I) placed at each load, preventing any accidental use in case of any swerving made by car (Fig. 5/5). <BR> <BR> b) -Indicator, to be adopted and conventionalise used and understood it would be placed at the back of the-vehicle, in order to advice the following vehicle of its capacity of an immediate brake-stop; c)-The triggering off of the load should be subordinate to the tension of the seat-belts of the relative seats (C-Fig. 5/5); <BR> <BR> d) -In vehicles in which the device is positioned too far forward it might be necessary to add a"barrier" (P, Fig. 4/5) (which would fold away) to safeguard any people or things that could be damaged from the jet of fluid.
