Description

“DI NÂMICA INSTALLATION WHEEL”

Subject matter:

[001] This Invention Patent refers to a dynamically installed wheel used in vehicles in general that proposes a new way of fixing the wheel that allows its removal quickly and easily, starting from a key tetra. The present innovation brings benefits mainly with regard to user safety at the time of an emergency tire change, and also prevents theft of the same. The traditional nuts that hold the tire in the wheel hub are replaced by a device that allows changing the tire from a tetra wrench and pressing a button that automatically releases the tire-wheel assembly, quickly, easily and safely.

State of the Art:

[002] The state of the art of the present invention has long been known for attaching tires to the wheel hub on vehicles using nuts, handled by a standard wheel wrench.

[003] The operation to replace the wheel-tire assembly for any reason is well known to the public, and generally requires strength, some skill and time. It is necessary to chock the opposite wheel, loosen the nuts, position the jack on the vehicle, suspend the vehicle and remove the nuts and, subsequently, the tire. It must be positioned correctly and the nuts must be tightened so that the reverse path can be taken. This procedure takes about 20 to 30 minutes.

[004] The need to replace a tire in an emergency may expose the user to various risks, in relation to his personal or property safety, as it may occur in remote and unsafe places, or in relation to your health, as it may not be able to do the necessary handling.

[005] There are palliative solutions to allow temporary running-in in cases of punctured tires, such as liquid glues for puncture obstruction, which can cause damage or even loss of the wheel, as a rule with a significant reduction in performance and speed. In addition to being temporary, this solution can become very dangerous, depending on the situation, such as on bad roads or in the rain, which would require adequate handling and braking performance to ensure the safety of the route.

In the 50s and 60s, tire solutions with internal tires were tested to enable temporary running-in in cases of flat tires. Run-flat tires were also launched, which have limited deflation and reinforced side walls that allow running in situations of pressure loss up to 80km / h and up to 80km.

[006] However, these solutions, although they help in emergency situations, have no influence on the change operation of the wheel-tire set itself, and this need remains. In addition, fixing the wheel-tire assembly by simple nuts, which, in a way, facilitates access to the user by standardization, makes frequent tire theft possible.

[007] Regarding mechanisms for rapid tire change, pneumatic devices used in races are known, as, for example, in Form 1 la, which require a car-wheel-tire-pneumatic key set for this purpose. purpose and synchronized performance, which is not made available to the user with one. [008] It is important to point out that the aforementioned problem becomes even greater in the occurrence of these situations in large vehicles, such as buses and trucks.

Inventive Concept:

[009] The present Dynamic Installation Wheel was developed to enable the simple, fast and easy change of the wheel-tire assembly in vehicles in general, using a tetra wrench, aiming to reduce the time applied in this operation and, consequently , reducing insecure situations to which the user will be exposed. It also seeks to enable users with less physical strength to also perform the operation, and avoid theft of tires.

[01 0] Therefore, this object aims to solve the technical problem related to the practical difficulty and delay in the operation of changing tires in vehicles in general. The new technical effect is in the installation on the hub and on the wheel itself of a mechanical device that allows the central fixation of the wheel and its activation through a tetra wrench, of single movement, which allows the removal of the tire after pressing a simple button and it also prevents the wheel from being stolen, as the tetra key can have its secret set up for each user.

[01 1] For this purpose, the traditional nuts that fix the wheel to the wheel hub will be replaced by a mechanism that includes a device fixed to the hub by a set of pins where the rim of the rear of the wheel is fitted, until it finds the lid packed in its own recess in the wheel.

[01 2] On the wheel hub, an overcub is fixed by conventional screws, the overcub being composed of protruding pins and star shape, on which the tire wheel assembly is fitted. Next to the wheel rim, they are fixed and fitted together a central lock and an anatomical handle, between which a cover is confined in order to accommodate a spring that provides the automatic operation of the mechanism, which are locked by the lock button, also responsible for activating it.

Application field:

[01 3] The application of this Dynamic Installation Wheel occurs as an automotive component.

Benefits:

[01 4] The Dynamic Installation Wheel has the following advantages:

• Provides quick, simple and easy replacement of the wheel-tire set, even by people with less physical conditioning;

• It allows emergency tire change situations to be quickly resolved, exposing the user for less time in unsafe or unknown places;

• Difficult the theft of a wheel-tire joint, since the key that allows its removal has 4 secrets, a tetra key, and can have such secrets configured exclusively for each user;

• Flexibility of use, as the mechanism can be installed in vehicles of the most diverse brands, passenger or cargo, small, medium or large;

• Ease of manufacture, as conventional industrial processes are necessary for the manufacture, as well as can be made of simple raw materials, such as stamped or forged steel, or in other materials, such as graphene, carbon fiber, aviation aluminum, alloys high-strength lightweight and high-strength polymers, provided the safety standards of each type of vehicle are met; • Ease of installation in existing vehicles or new vehicles, which can already be installed at the factory;

• It allows the consumer to make aesthetic choices regarding the wheel, since several wheel models can be tested on the vehicle in a practical and quick way.

Description:

[016] The Dynamic Installation Wheel is made up of the sub-hub (1) equipped with conventional holes (2) directly coupled to the rear rim of the wheel (3) for adaptation to a common automotive axle, where the fixing means (4 ), such as screws. The drilling of the subcube (1) must accompany the drilling of the different wheels used by the market, for different brands, models and sizes of vehicles. The face (5) of the sub-hub (1) coincides with the rim of the rear wheel (3), being perfectly flush with it, and the star-shaped surface (6) with rounded corners coincides with the wheel disc (7), being, likewise, leaning perfectly against this one. The sub-hub (1) is fixed to the wheel hub by conventional screws. The fixing means (4) the rim of the rear of the wheel (3) and fix the cover (13) contained in the central recess (12) of the wheel. [017] Above the surface (6) the sub-tube (1) protrudes the locking pins (8), all equipped with an internal lateral slot (9) and centralizing axis (10), which are distributed substantially equidistant around the central hole (11).

[018] The centralizing axle (10) may, in some cases, be eccentric or even non-existent, as it is intended for the passage of the guide pin found in some types of automotive axles.

[019] The wheel (3) has the central recess (12) to hold the cover (13) and the smaller recess (14) for fitting the central lock (15).

[020] The cover (13) is provided with a substantially elliptical recess (16) for connection to the through-hole (17) of the wheel (3) and the substantially elliptical edge of the locking button (18) fitted with the screw (19). screwed on the substantially elliptical end (20), followed by the passage area (21) and lower hole (22). The spring (23) is located over the lock button (18) located below the elliptical end (20). The holes (24) of the cover (13) are fitted on the locking pins (8), and the central hole (25) fits the central lock (15). The oblong recess (26) coincides with the oblong recess (27) of the anatomical handle (28), both being superimposed in order to hold the spring (29) inside, whose function is to open the central lock (15) automatically after release button lock (18)

[021] The anatomical handle (28) has an upper part (30), with an appropriate shape for the manual twisting movement for locking and automatic opening movement of the piece, and the lock (31) with a cylindrical tongue (32) inferiorly, which fits into the bottom hole (22) of the lock button (18). [022] The central lock (15) is provided with a flat base (33) from which follows the cylindrical extension (34) provided itself, laterally, with an oblong hole (35) with a thin end (36) where the area is fitted through (21) of the lock button (18). The function of the thin end (36) of the oblong hole (35) is to allow the central lock (15) to rotate counterclockwise and automatically when the device is to be unlocked.

[023] The fixing of the central lock (15) is done by means of fixation, such as screws, fitted in the holes (37). The inner face (38) determines the contact area with the anatomical handle (28) and the recessed area (39) for the locking button (18) in its two positions: locked or unlocked.

[024] The 10 fixing means (4), preferably hexagonal screws, are intended to fix the cover (13) on the wheel (3). The fixing means (4) pass through the holes of the rolling disc (7) until the central recess (12) of the wheel (3) reaching the cover (13). The central lock (15) is fixed to the anatomical handle (28) by 4 fastening means, preferably hexagonal screws, keeping the cover (13) between them, in order to allow the locking area (21) of the lock button ( 18) at the thin end (36) of the oblong hole (35) through the elliptical recess (16) of the cover (13), so that the locking button (18) is housed in the recessed area (39). The anatomical handle (28) is fitted over the central lock (15), in order to coincide its oblong recess (27) with the oblong recess (26) of the lid (13), both being overlapped in order to fit in its inside the spring (29), which will release the central lock (15) automatically after releasing the lock button (18). The lock (31) of the anatomical handle (28) fits into the bottom hole (22) lock button (18), allowing manual device locking and unlocking.

[025] The handling by the user of the device takes place as follows, to remove the tire wheel set from the vehicle: the tetra key is fitted to the lock (31) and the lock button (18) is pressed, which will release the anti-movement -time of the anatomical handle (28), releasing the wheel-tire assembly for removal. Due to the arrangement of the pieces, the spring (29) has the function of expanding, causing the anatomical handle (28) to rotate counterclockwise (28), since this is connected to the central lock (15), it will loosen the plug-in pins (8) of the sub-tube (1). The sub-hub (1) will remain fixed to the wheel hub, with the tire and other components removed. The new wheel tire set must be positioned in order to fit the sub-tube (1) to the wheel (3), the anatomical handle (28) is rotated clockwise and the lock (31) is tightened, ending the change of the wheel-tire assembly.

[026] The lock button (18), when not pressed, prevents the center lock (15) from turning counterclockwise. Once the lock button (18) is pressed, the passage area (21) allows the central lock (15) to yield to the spring pressure (29) and rotate the coupled parts. The central lock (15) and the anatomical handle (28) then rotate counterclockwise, releasing the locking pins (8) from the sub-tube (1), allowing the immediate release of the tire-wheel assembly.

[027] The anatomical handle (28), due to its constructive format, replaces the hubcap, when compared to a traditional wheel.

[028] The mechanisms described here can be used together with the most diverse models of existing wheels, as well as suitable for passenger vehicles or car transport or people, small or large. Small changes may be necessary on a case-by-case basis, but the constructive and functional concept described in this patent always remains.

[029] Optionally, the present mechanism described here can be incorporated into vehicles still in manufacture, and for that, it is sufficient that the wheel hub be manufactured in the shape of the sub-hub (1), which will be able to receive the dynamic installation wheel. directly. In this case, it is not necessary to fix the sub-tube (1) on the vehicle, as it will already be integrated with it, making the set even easier to be installed and handled.

Conclusion:

[030] Thus, the Dynamic Installation Wheel is subsidized by unprecedented technical and functional characteristics, therefore deserving the legal protection sought.
