Description

1 / 10 Emergency Braking System for Trucks and Trailers Field of invention

[001] The present invention patent relates to a practical and innovative emergency braking system for trucks and trailers, belonging to the field of automotive equipment, more precisely for use in heavy vehicles such as trucks, trailers, buses and the like, and to which an original constructive arrangement has been given, with a view to improving its use and performance in relation to other products usually found on the market.

[002] More precisely, it is an emergency stop system comprising a braking track, which is activated by the driver in the event of a failure in the vehicle's main brake.

[003] The patent application in question therefore presents a system specifically designed and developed to achieve great practicality and which offers significant advantages, both in its use and in its manufacture.

[004] It is also the objective of this application to present an emergency braking system for trucks and trailers with low costs for its industrial feasibility, but combined with the requirements of robustness, safety and practical utility, thus offering the consumer public an additional option in the market of similar products, which, unlike usual products, offers numerous possibilities and benefits to its users, becoming a product of great acceptance in the consumer market. State of the art Petition 870200134008, dated 10 / 23 / 2020, page 4 / 23 2 / 10

[005] As experts in the field know, in order to stop or simply reduce the speed of a heavy vehicle, the brake linings and pads come into contact with the brake drums and discs, respectively, and through the force of friction, convert the vehicle's kinetic energy into heat.

[006] Once the vehicle's braking system becomes inoperative, the driver is left without the means to stop it, which can cause very serious accidents, even resulting in fatalities, given that the vehicle's gross mass is enormous and its kinetic energy is always immeasurable, even if its speed is not relatively high.

[007] There are several factors that can cause changes in the operation of a heavy vehicle's braking system.

[008] The braking system of most heavy vehicles such as trucks is pneumatic, that is, it works by means of the pressure exerted by the air. If this pressure is not properly regulated, or if the system has leaks, the truck's braking may be compromised.

[009] The most common causes of pressure loss in the system are problems with valve seals, contamination by engine lubricating oil, and water accumulation in the air reservoirs.

[010] Another fairly common cause of altered brake system operation is overheating – when the brake linings and drums are in poor condition, applying the brakes can result in overheating of the system. In this situation, the friction between the Petition 870200134008, dated 10 / 23 / 2020, page 5 / 23 3 / 10 components decrease, reducing the efficiency of the truck's braking. Another reason is inadequate clearance between the brake pads, in vehicles with disc brake systems.

[011] In trucks equipped with hydraulic brake systems, the pressure on the components is exerted by the brake fluid. For this purpose, it has some special characteristics, such as low compressibility and a high boiling point. The most common problems in these cases are leakage and contamination of the fluid. When this happens, its properties are compromised, which can result in problems with the truck's braking.

[012] One factor that cannot be overlooked is overloading, which substantially increases the risk during braking.

[013] In order to avoid or minimize damage caused by brake system failure in a heavy vehicle, various systems and methods are available. In this respect, and in order to specify the state of the art, some patent documents can be cited that deal with equipment and systems with the same conceptual purposes, but without achieving the inventive merit and the differences revealed here, as follows below.

[014] Patent document PI0615656-8 A2 entitled DEVICE AND PROCESS FOR CONTROLLING AN ELECTRIC LOCKING BRAKE OF A UTILITY VEHICLE, discloses a device for controlling an electric locking brake of a utility vehicle, with an electronic control unit and a manual control unit, which is in communication with the electronic control unit, through which Petition 870200134008, dated 10 / 23 / 2020, page 6 / 23 4 / 10 The driver's wishes, dependent on the type of control of the manual control unit, are transmitted to the electronic control unit, the electronic control unit being configured in such a way that it additionally processes the signals from the manual control unit when the ignition of the utility vehicle is switched on. According to the invention, the manual control unit is configured in such a way that, with at least one type of control, it emits a warning signal (WUP) to the electronic control unit, and furthermore, the electronic control unit is configured in such a way that, subsequent to receiving a warning signal, it additionally processes at least one other signal (Sl) from the manual control unit, even when the ignition of the utility vehicle is switched off. The invention also relates to a process for controlling an electronic locking brake.

[015] Patent document BR 112019005070-1 A2 entitled PARKING BRAKE DEVICE FOR UTILITY VEHICLE, discloses a parking brake device for a utility vehicle with at least one control valve device, with at least one relay valve, with at least one pneumatic braking device and at least one trailer control module, wherein by means of the control valve device, the relay valve is controllable and wherein by means of the relay valve at least the pneumatic braking device is controllable, wherein upstream of the trailer control module there is a valve, which has a first connection and a second connection and a third connection, wherein to the second connection is connected a second connection line, which connects the valve with the Petition 870200134008, dated 10 / 23 / 2020, page 7 / 23 5 / 10 control valve device, in which a third connection line is connected to the third connection, which connects the trailer control module to the valve, in which a first connection line is connected to the first connection line, which is connected to a first line, which is located downstream of the relay valve.

[016] Patent document PI0208816-9, entitled DISC BRAKE FOR HEAVY TRUCK AND A VEHICLE INCLUDING SUCH DISC BRAKE, discloses a disc brake for a heavy vehicle, comprising a disc-shaped rotor, consisting of a cast iron alloy and a caliper supporting a brake lining that is designed to be pressed against said rotor during a braking action.

[017] Patent document BR 102015003670-1 A2 entitled EMERGENCY BRAKE DEVICE FOR A VEHICLE, PREFERABLY FOR A TRUCK AND TRUCKS, relates to an emergency brake device for a vehicle, preferably for a truck, characterized in that it comprises at least one spring-operated brake cylinder; a first electrically controllable valve device that is configured to initiate an air exhaust and / or a filling of at least one spring-operated brake cylinder as a function of an electrical control signal.The emergency brake device also comprises a second switchable valve device having a pneumatic control input and an electrical control input, which is configured to initiate an exhaust of at least one spring-operated brake cylinder if a pneumatic pressure present at the pneumatic control input is less than a predefined limit value and if no electrical current is available at the input. Petition 870200134008, dated 10 / 23 / 2020, page 8 / 23 6 / 10 electric control. Weak points of the state of the art

[018] The major drawback of these models lies specifically in the fact that they have complex designs, involving numerous mechanical, electrical, pneumatic and hydraulic components, which result in substantial production costs, therefore they are only applicable to more sophisticated and higher-priced vehicles. The lower-cost trucks that make up the majority of the utility vehicle fleet do not include these emergency braking equipment models. Proposed solution

[019] It was with these inconveniences in mind that, after numerous research and studies, the inventor, a person connected to the field, created and developed the object of this patent, designing an emergency braking system for trucks and trailers in which not only the mechanical and functional qualities were considered in the design of its manufacture, but also the shape, arrangement and location of its parts and components which, correctly positioned, brought an increase in efficiency without incurring any burden.

[020] More precisely, it is a system that deploys tracks under the tires of the heavy vehicle, aiming to bring it to an emergency stop.

[021] Thus, the present patent was designed to obtain a product with the fewest possible number of parts, conveniently configured and arranged to allow the emergency braking system for trucks and trailers to perform its functions efficiently and versatilely. Petition 870200134008, dated 10 / 23 / 2020, page 9 / 23 7 / 10 unparalleled, without the aforementioned drawbacks.

[022] This patent application presents a practical and innovative emergency braking system for trucks and trailers with all the aesthetic and functional qualities, designed and developed according to the most modern techniques, thus enabling its most varied use, from use in trucks to use in trailers, as well as in use in buses in general.

[023] Its innovative concept allows for an excellent level of functionality, offering an emergency braking system for trucks and trailers that is very simple, having been created primarily to serve all types of heavy vehicles with low cost and utilitarian reliability.

[024] The system configuration, the subject of this patent, comprises a sequence of events that, in the event of a failure in the main braking action of a heavy vehicle, through an action by the driver in the cabin, activates the command that releases the tracks, which are positioned on the vehicle's axles. The wheels will pass over the track that has fallen under the wheel, which will automatically brake the vehicle, thus preventing an accident.

[025] It is therefore understandable that the system in question is extremely simple in its construction, and therefore easy to implement, yet it achieves excellent practical and functional results, offering an innovative construction compared to known products.

[026] Designed with an innovative concept, it results in a harmonious set, with a rather peculiar aspect and, Petition 870200134008, dated 10 / 23 / 2020, page 10 / 23 8 / 10 especially characteristic, and in addition to its construction, the product stands out for its versatility and ease of use.

FIG. 6 - Shows a perspective view. Petition 870200134008, dated 10 / 23 / 2020, page 11 / 23 9 / 10 of a tractor unit with the emergency braking system installed on the wheels of one of the axles, where the data reception and transmission points for the operation of the tracks can be seen. Detailed description of the invention

[028] In accordance with what is illustrated in the figures above, the EMERGENCY BRAKING SYSTEM FOR TRUCKS AND TRAILERS, the subject of this patent, comprises an emergency vehicle stopping system comprising tracks positioned appropriately near the vehicle's tires, so that, when activated by the driver from the cab, they are instantly launched under the respective tires, stopping the vehicle instantly as soon as the tires rise onto them.

[029] More precisely, the emergency stop system (1) comprises tracks (2) positioned close to the vehicle’s tires (3), where said track (2) is attached to a structure (4) mounted directly on the chassis (5).

[030] Each structure (4) comprises a platform (6) which has above it a stop belt (2) arranged in layers which are mutually affixed with polymeric straps (7), one end of said belt (2) being affixed to the structure (4) by means of at least one helical spring (8) and the other free end being affixed to the quick actuation device (9).

[031] Said actuation device (9) is pneumatically or hydraulically connected to a pedal (10) or control button (11), positioned in the cabin (12), which is operated by the driver himself, in case of failure of the vehicle's main brake. Petition 870200134008, dated 10 / 23 / 2020, page 12 / 23 10 / 10

[032] The use is extremely simplified, the vehicle driver only needs to press the emergency pedal (10) or button (11) when noticing a failure in the vehicle brakes.

[033] When the said emergency pedal or button is activated, the drive device immediately launches the ends of the tracks in front of the tires and sequentially the polymer belts are broken by the force of this action itself, and as soon as the tires rise onto the tracks the vehicle is stopped immediately, thus avoiding an accident.

[034] Although the vehicle comes to a stop quickly, the coil springs (8) dampen its stopping and prevent damage to its structure and components and also preserve the physical integrity of the occupants.

[035] The conveyors (2) can be activated simultaneously or individually in clockwise or counterclockwise action, depending on whether the vehicle is moving forward or backward.

[036] It is understood that when the present invention is put into practice, modifications may be introduced with regard to certain details of construction and form, without departing from the fundamental principles that are clearly substantiated in the claims, it being understood that the terminology used was for descriptive purposes and not for limitation.
