Description

Enhanced Slip Device built into the tire.

Object of the invention

The invention presented refers to a non-slip device of those placed on the wheels of cars to ensure driving conditions when The road has snow or ice. It's about improvement of an invention by the same author entitled "Tire with device of built-in strings "corresponding to the request number U200900853 and publication number 1070265.

The author incorporates an improvement to his previous invention, which is of the manual type, consisting in that grip plates on the ground are in solidarity with the arms that they support them and cannot be folded on them which implies the Design of a tire with holes to house the plates. In addition the tire may have aeration windows or, alternatively, be closed inside so that you avoid arms get dirty and greater mechanical safety is achieved of the set The outer part is protected by the hubcap. Finally, another important consistent improvement is conceived in the automation of said device, such that the driver of a car equipped with the non-slip system you can activate and deactivate it with minimal effort following a very simple process.

Sector of the technique to which the invention relates

The present invention has its effects within of the scope of the Section of Various Industrial Techniques in the chapter of Transportation in relation to Automobiles, influencing, from an industrial point of view, the manufacture of accessories for motor vehicles, specifically tires.

Background of the invention

According to the state of the art, there are available to the public numerous types of devices Non-slip for use by motorists when the routes through which you want to travel are affected by ice or the snow

The devices can be classified into four basic groups:

       \ vskip1.000000 \ baselineskip
    

1.- Those incorporated in the tires themselves

Among those incorporated in the tires themselves we can mention the nail wheels, the stud tires Specials or sprays for immediate application.

The nail wheels should be properly in advance of the winter season or carry a game in the trunk to place them when necessary. In some countries the regulations are very strict because they can damage the road if there is no snow cover or minimum thickness ice.

Taco tires can be useful exclusively in case of snow being noisy on exempt roads of snow.

As for sprays they are also useful for snow cases and only recommended and effective for cases unforeseen or to get out of some trouble.

       \ vskip1.000000 \ baselineskip
    

2.- Those of chain type

They are the most common and there are in multiple variants. They should be put on when there is already ice or a good layer of snow. Therefore, the chain equipment must be carried in the trunk to place them when it is essential due to the demands of the traffic authorities or by simple precaution. Your placement is complex and uncomfortable because it always matches when conditions Atmospheric are very adverse. It is also necessary to place them very well to avoid noise and possible damage to the mechanics of the own car.

       \ vskip1.000000 \ baselineskip
    

3.- The band type

These are very light equipment that conform to the tread surface of the tire. They can be simple bands textiles or complemented with other materials that improve the adherent properties of the set. They take up little space in the trunk and, being more manageable, are more simple to placement, having the inconvenience of presenting a very useful life short.

4.- Those of the spider type

Each time they have a greater degree of acceptance because They are easier to place and have good adherent qualities. They must be carried in the trunk with the inconvenience they occupy a lot of space, they are relatively heavy and their price is high.

In summary, we can say that none of the Existing types successfully solves the problem posed for snow and ice either because of the difficulty of placing it and withdrawal, because of the need to take it preventively in the trunk with the negative aspect of the volume occupied, either by the serious inconvenience of having to do the placement and removal in adverse weather conditions, due to its higher or lower price, etc.

Some models, especially those of type spider, have gone on the market with easy and fast designs placement but, in any case, the problem in a totally satisfactory way though, in that sense there is an invention, mentioned above, devised by the same author of this document that has the particularity that the device is included in the car tires, such so that when the need for their placement arises, they are always available and can be adjusted quickly and simple.

The invention now presented takes a step more than the previous one, in the sense of, on the one hand, incorporate improvements in the arms and the rim and, by On the other hand, automate the placement of non-slip devices The device installed on each wheel It is additionally provided with a hubcap, but Logically, it is not essential. The proposed solution contemplates, finally, a total automation in which it is not necessary disassemble the hubcap to activate the device anti-slip.

Description of the invention

The present invention, as it has remained exposed in the introduction, refers to a device non-slip of those placed on the wheels of the cars to ensure driving conditions when the Road presents snow or ice. It's about perfecting an invention of the same author corresponding to the application number U200900853 and publication number 1070265. That is the device is integrated into the car's tire so that it is not precise storage in the trunk until the moment its use is necessary.

The improvement presented in this document refers first to the radial arm system that were presented before with some plates that folded over these arms and now they are designed fully in solidarity in them what demands a design of the tire with some cavities where they lodge the plates during the periods of non-use of the non-slip system

On the other hand a solution for the device automation in order to achieve its deployment and pick-up when the driver considers it appropriate based on the ice and / or snow conditions that the road presents.

In all cases it is a tire special, blind or with aeration windows, inside, which incorporates a series of arms, arranged radially, in number that should preferably range between six and nine to increase the probability that some of them are in contact with the ground and optimize the grip on snow or ice. Each arm is of type telescopic being able, therefore, to modify its length from a minimum value defined by the inner diameter of the tire, that is which corresponds to the ring through which the inflation valve of the pneumatic, up to a maximum value defined by the outside diameter of the tire that is the one that contacts the ground.

In the case of the drive device manual, the end of the arm closest to the wheel axle, pivots on protruding bearings of the tire while the arm is in resting device situation, substantially parallel to the plane of the wheel. At the other end of the arm is the plate oriented towards the inside of the tire on which it has been to rewind an area in order to accommodate the plate. Be could solve that interference with simple perforations in the tire but the inventor designs the tire with those sunken areas with the purpose of avoiding splashing or dirt phenomena coming from the engine or road that stain the device anti-slip. This also ensures greater mechanical safety in forecast that any of the device elements non-slip could break down and get fired at high wheel speed However, the above not excludes the possibility of providing the window rim with aeration. The outer part of the tire is protected in periods of device inactivity with a simple hubcap that is accurate disassemble at the time you want to activate the device. For it will be enough to pull the arm for the part closest to its corresponding plate making it rotate on its axis until the plate comes out of the hollow of the tire that protects it, in whose moment you can pull the telescopic assembly as necessary to be able to fit the plate on the tire by turning the arm assembly on its axis.

The inner springs of the telescopic assembly keep the plate attached to the tire even if it suffers deformations of the rolling process.

In the case of the automated alternative, the arm end closest to the wheel axle, is in solidarity with a telescopic group that, together with the tire, can be extended in horizontal direction in two, three or more sections with the result that the arm can move away from the tire in the length defined by the sum of lengths of the telescopic sections. The other end of arm, the furthest from the wheel axle, is crowned by a curved plate, identical or similar to the previous case, which sensibly adapts its curvature to that of the tire mounted on the tire. This plate, oriented axially, is equipped with all cases, on both sides, of high reliefs or nails which facilitate adhesion to the tire itself and to snow or ice of the road.

With this arrangement the set of arms they can vary their position on the tire from a resting position, of minimum length, with the plates housed in the proximity of its inner ring, to the working position in which each arm is extended in maximum length and each corresponding plate is coupled, exerting some pressure, on the perimeter part external tire The tire, in this alternative solution It is also equipped with sunken areas that house and protect the corresponding plates.

As will be discussed later, the motorization for the aforementioned deployment to occur, it is achieved preferably by hydraulic means that can act from the wheel bearing or from the outside of the tire. They are not discarded other means such as pneumatic or electric.

Each tire incorporates a hubcap trim which hides, in part, the set of telescopic arms. At optimal case, the driver may order the extension or withdrawal of the non-slip device from inside the car without the need to remove the hubcap.

In the drawings included in this document you can see the deployment and coupling process defined by its main phases, both in the first case and in the second.

Description of preferred embodiments Alternative 1

Enhanced Slip Device incorporated into the tire (3) (Figs. 1 to 9) consisting of a tire special designed in such a way that incorporates a device intended to act as non-slip in cases of roads with snow or ice In an embodiment preferred by the inventor It is described in a manner similar to how it is done in the invention of same author with application number U200900853 and number of publication 1070265, that is, as a tire (1) incorporating a non-slip device (3) consisting of a series of arms (5) arranged radially in number, which preferably should be from six to nine. Each of the arms (5) that is of type telescopic, with three or more sections, has an axis of rotation on a chumacera (4) located in the vicinity of the wheel axle and in the other end has, rigidly attached, a plate (6) designed with a shape that fits the tire (8), each having plate (6), on both sides, a series of nails (7) intended for favor the grip of the wheel on snow or ice. Insists in which the plate (6) is rigidly attached to its corresponding arm (5) unable to fold over it, which constitutes one of the improvements of the current device with respect to previous.

Under these conditions the interference of each plate (6) with the external surface of the tire (1), which is achieved by designing said tire (1) with a series of cavities (2) or sunken areas that admit the accommodation of the corresponding plates (6), this being another one of the improvements that are now contributed to the device presented previously. The cavities (2) are blind with which, even with the inconvenient of damaging aeration, they have the advantage that the tire itself (1) becomes a kind of shield that favors cleaning and avoids possible mechanical breakdowns by decomposition of any of the elements of the device non-slip (3) that could cause the projection of pieces on important parts of the engine, steering, brakes, etc. Must have Note that this non-slip device (3) is designed to be permanently mounted on the vehicle whereby your rotation speed is very high when driving at maximum speeds allowed for each road. In any case the inventor conceives the possibility of designing aeration windows in other places of the tire, without prejudice to safety even if to the detriment of cleaning.

Externally the non-slip device (3) is protected by a hubcap (9) of the usual represented schematically in (Fig. 1). Although it is represented without openings, It can also be designed with windows.

The invention thus conceived allows a maneuver easy to move from the collected position represented in (Fig. 1), to the deployed position of (Fig. 2) where it should be noted that with the plates (6) attached to the tire (8) the arms telescopic (5) fit between stops (1.1) integral with the tire (1).

The maneuver begins by removing the hubcap (9) attached to the rim (1) by a screw (10) or by any other means, medium. Then, as shown in (Fig. 3b), it is rotated the arm (5) with its plate (6) on the bearing block (4) until a position that allows to extend the arm (5) by sliding of its telescopic sections (Fig. 3c). Finally the set is rotated on the shaft of the bearing block (4) until the plate (6) is coupled on the tire (8) with a slight pressure that can be favored by internal springs (not shown). Arm fits between stops (1.1) that improve the efficiency of the anti-skid device (3) to the tractive stresses of the car wheels

The operation is repeated with each arm (5) until that all are coupled on the tire (8), which can require some movements of the vehicle in the event that any of the plates (6) interfere with the ground or also depending of the gap between wheel and fender of each car, which in Some cases is very small.

It is understood that with the device non-slip (3) deployed, car speed must be limited to what is usual with any other device, that is to say about 40-50 km / h. The arms (5), as they are conceived, they conform to the small deformations of tires (8) motivated by rolling itself, potholes etc.

As for the reverse process, to move from Position deployed to pickup, does not require further explanation.

Alternative 2

This alternative (Figs. 4 to 9), supposes a improvement of the previous one directed to the automation of deployment and collection of the non-slip device (3).

In this case, the side closest to the axis of the wheel of each arm (5), is in solidarity with a core (4.1), also telescopic, with three or more sections that can be extended in axial direction with the result that the arm (5) can move away from the tire (1) for the purposes that will be described later.

The other end of each arm (5), the most away from the wheel axle, it also sympathizes with a plate (6), curved, which adapts its curvature to that of the tire (8) mounted on the rim (1). This plate (6), oriented axially, it has, on both sides, some reliefs or nails (7) that facilitate adhesion to one's own tire and snow or ice on the road.

An important feature of the two telescopic sets is that they have absolutely restricted the relative rotation of one section over another in the plane perpendicular to its longitudinal axis which is achieved using any type of cross section except circular. That is, each section alone it can slide with respect to its contiguous longitudinally.

The device deployment process non-slip (3) from the resting position inside the rim (1) to the working position on the tire (8) records a succession of multiple intermediate positions, some of which are represented in (Fig. 9) in which in the left part (Fig. 9a) the resting position is reflected. Note that the rim (1) is also designed with holes (2) that allow the housing of the plates (6). In (Fig. 9b) the core (4.1) is with its telescopic sections deployed which implies that the arms (5) move away from the rim (1) in length enough so that the vertical projection of the edge of the plates (6) does not interfere with the leading edge of the tire (8). In the (Fig. 9c) the core (4.1) is maintained with its sections deployed, the telescopic sections of the arms (5).

In (Fig. 9d) the telescopic sections of the core (4.1) are collected, the sections being deployed telescopic arms (5). This allows the plates (6) come into contact with the tire (8) with a final phase, not represented, in which there is a retraction of the arms (5) so that the plates (6) exert some pressure on the tire (8) the vehicle being able to ride on snow or ice.

The process just described based on the drawings of (Fig. 9), which do not incorporate the hubcap (9.1) bezel, can be done in the same way when the hubcap (9.1) is mounted on the rim (1) since the aforementioned hubcaps (9.1) is designed with recesses (14) that prevent mutual interference without preventing the deployment or withdrawal of arms (5) (Fig. 7).

As for the motorization of the device Non-slip (3) follows, as indicated above in this alternative, which should affect the nucleus (4.1) and the arms (5) which are the only parts susceptible to movement in said device. The inventor conceives as a preferred solution that of apply a hydraulic or pneumatic solution for the movement of the telescopic sections of both the core (4.1) and the arms (5), applicable solution for both-way movement, is that is, for the deployment of the non-slip device (3) up to its working position and for subsequent withdrawal until the resting position Other procedures of motorization like electric.

Whereas movements occur antagonistic in core (4.1) and arms (5) cannot solve the motorization with a single hydraulic circuit being forced the have two independent circuits, one for the system telescopic core (4.1) and another for the telescopic system of the arm assembly (5).

For the application of hydraulic pressure, by the arrangement of the elements of our device there are two preferred solutions. One of them, more simply, is the external connection coinciding with the wheel axle, specifically through the hole (15) of the screw (10.1) (Figs. 7 and 8).

The other, more complex to affect more pieces of the car, it is through the shield (13) that must be perforated longitudinally.

In either solution, the inventor provides two independent circuits for separate action on the core (4.1) and on the arm assembly (5) either for its deployment or for its withdrawal.

The movement of said telescopic assemblies is commanded from inside the car where there is a control center with specific controls for each wheel and for core (4.1) or arms (5) well understood that the coordination of these movements is automated since the process deployment or withdrawal always follow the same
Steps.

It should also be considered as restrictive feature, which at the time of placement or removal of the non-slip device (3), the coincidence that one of the arms is in a position that interfere with the floor or with the car body. For to solve this problem it is expected that the placement or withdrawal of the arms (5) be selective ordered by the driver himself or, preferably, by the control center. After the performance on one wheel will be passed to the next.

Different tire designs are not ruled out (1) with stops (1.1), as described in alternative 1, for avoid relative movements of the non-slip device (3) regarding its corresponding wheel during the march because tensile stresses tend to favor such movements.

This induces even to execute designs special arms (5) in which the section of the telescopic have greater inertia in the plane parallel to the wheel than in the corresponding perpendicular plane of axial direction.

It is not considered necessary to make the content of this description for a subject matter expert can understand the scope and advantages derived from the invention, as well as develop and implement the object of the same. However, it should be understood that the invention has been described according to a preferred embodiment thereof, whereby may be subject to change without implying any alteration of the basis of said invention; that is, the terms in which this preferred description of the invention, should always be taken broadly and not limitative.
