Description

CLAMPING SYSTEM FOR CHAMPION WHEELS AND JREMOLQUÉ FIELD OF THE INVENTION The present invention relates to a fastening system for truck tires and transport trailers and, more particularly, relates to a construction that will prevent said wheels, which accidentally detach from their secured position of the moving vehicle, from traveling. Without restriction and caü? in Bath in property, injury or death. BACKGROUND OF THE INVENTION In trucks and transport trailers there are wheels that are bolted in place. There have been wheels and assemblies of wheels, trucks and trailers, which are accidentally detached from the vehicle in motion. Once detached the wheels or assemblies will travel without restriction causing damage to property, injury or death. At present, there is no method to restrict the wheels or wheel assemblies, accidentally detached in transportation vehicles. The current norm is to rely on the installation of the wheel, and the wheel assembly, without any secondary restriction mechanism. This system allows the The original installation mechanism fails completely and still holds the wheel or wheel assembly to the vehicle. The wheel assembly, when in operation, is a relatively heavy rolling mass, which is mounted on an axle, which uses bearings and a wheel hub. Problems will occur when the wheel breaks or separates the hub from the wheel, the wheel bearing and / or the wheel hub fails, or the shaft breaks. In these situations, some or all of the wheel assembly will separate from the vehicle and will not be restrained. 10 In all these failure situations, the portion of the wheel or wheel assembly that comes off must move away from the vehicle in an unrestricted manner. They are a background of interest: The U.S. Patent No. 2,627,437 of KI.H. Toncray et al., Issued on February 3, 1953 and the U.S. Patent No. 5,462,324 to Bowen et. al., issued on October 31, 1995, respectively describing a construction in the automobile frame and a wheel guard attachment for motor vehicles.

BRIEF DESCRIPTION OF THE INVENTION In accordance with the present invention, a restriction system for a wheel mounted on a vehicle axle is provided, the vehicle having a frame to which the vehicle is secured. axis, leaving enough free space to avoid risks from the that may be included within the spirit and vision of the invention as defined in the appended claims.

DETAILED DESCRIPTION OF THE PREFERRED MODALITIES In the following description, similar features in the drawings have been given similar reference numbers. Referring to FIGURE 1, there is shown a fastening system 2 for wheels 4, which are mounted on a hub 6 secured to the axle 7 of a trailer 8. The fastening system 2 comprises a cage 10 made of bars or plates 12, preferably made of steel for springs. The cage 10 is welded or otherwise secured to the frame 14 of the trailer 8 and is constructed to expose only the lower portion of the wheel 4, allowing contact of the wheel with the road and to leave sufficient clearance to avoid risks of the path. Preferably, the box is supported by angled struts 16. It has been found that a clearance of approximately 5.1 cm in front of and behind the wheel, and 3.8 cm in front of the outside of the wheel and 5.1 cm in the outer rear part of the wheel. the wheel, are appropriate to provide an unobstructed operation of the vehicle under normal circumstances. The outer clearance for the wheel must be less than the distance that the wheel must move laterally and outward, to exit from the hub 6. Equally, having the free space on the front side slightly smaller than the outer rear free space, if a When the wheel is released during the forward movement of the vehicle, the cage will act to direct the wheel inwards and back to its position on the wheel hub 6. In operation, the restrictor bars 12 of the cage 10, prevent the wheel 4 exhaust away from the side, or under the vehicle. Of course, the actual physical construction of the cage 10 may vary. Extending a covering of a cage 10, as well as the location of the bars 12 on the side, would be dictated by the requirements and appearance of the vehicle or trailer in which the cage is mounted. The wheel cage should have enough strength and fixation to support the load of the vehicle on the cage, without its total destruction or detachment. 15 Alternate constructions of cages, illustrated in FIGURES 4 and 5, show such constructions for trailers where the wheels 4 extend outwards, beyond the side of the frame 14 (FIGURE 4), and where the wheels 4 are located below of the frame 14 (FIGURE 5). In these modalities, the The securing of the cage 10 on the frame 14 is further reinforced by angle bars 17 extending between, and secured to, the portions of the frame and the spaced locations on the frame 14, as illustrated. The cage 10 may have optional plates or bands (no illustrated) that would act as fenders and / or fenders. Equally, using the cage 10 as a safe place for mounting, optional side fenders (not shown, either) can be mounted along, laterally, of the vehicle, both in front of and behind the wheel cage, to offer some protection against other 5 vehicles or people who will be trapped under the wheel and therefore substantially reduces the risk to road users. Various warning flags, sensors and alarm devices can be fixed as desired to the restriction bars 12 of the cage 10, or another suitable place, to draw the operator's attention to the wheel or the wheel assembly of the vehicle. vehicle that has been retained. The wheel attachment cage 10 according to the present invention can be mounted firmly to the frame of the vehicle using, for example, a mounting plate 18 fixed to the frame by screws 20. The mounting plate has arms 22 attached thereto, which extend laterally from the frame of the vehicle in very close proximity to the wheel. Those arms 22 are made of metal tube or plates and are fixed in their position. These arms extend outwardly to approximately 2.5 to 5.0 cm from the outer edge of the rim 4 of the wheel assembly. On the outer edge of the arms 22 there is a mounting plate 24 for fixing the restrictor arms or plates 26. (The arms 22 and 26 form the restricting bars 12 of the cage 10). This way, if a wheel 4 is released from its bolted position on The components of the cage 10 are manufactured so that the clearance from the operating wheel is kept to a minimum, so that those portions of the wheel, or the wheel assembly, that can be accidentally detached from its operating position. , are restricted within the wheel cage 10. As an option, a mechanism (not shielded) can be installed to prevent vehicles or people from accidentally arriving under transport trucks or trailers during side contact, or to avoid that they are caught for the wheel assembly. Using a secure mounting of the wheel cage and installing another similarly secure assembly further along the side of the truck and / or trailer, a side fender would be installed to prevent vehicles or people from entering under the vehicle in question. It will be understood that the screws 29 supporting the side arm 26 can be removed to allow the removal of the arm 26 from the arms 22 when it is required to remove the tire on purpose, for example, for repair or replacement. The level of the lateral arm 26, as seen in FIGURES 1 and 2, for certain "constructions of wheel assemblies or certain applications, can be secured in a raised position (not shown) with respect to the wheel hubs, or in a lower position (not illustrated) with respect to them. - The components of the cage 10 can be made from metal or other materials such as resistant plastic or a combination of them. The cage 10 can alternatively have its components made of flexible material such as spring steel so that it will regain its original shape if it is hit by something externally. As an optional embodiment of the wheel cage, according to the present invention, a rotating or low friction part 30, such as a wheel or bearings or a skating plate, mounted on the arm 26, illustrated for example in the FIGURE 3, may be provided to facilitate the continuous rotation of a detached wheel 4 when it contacts that portion of the arm 26. A sensor 32 may also be associated with that part to detect a change in its operation or condition, and . Provide a signal, for example audible or electronic to the driver's cab, to alert the driver to the problem of a wheel detached or in the process of detaching. As another optional embodiment, a flexible curtain 36 (shown in Figure 2), for example made of rubber, can be suspended from the arm 26, and / or arms 22 to minimize splashing of nearby wheels 4 on wet roads. twenty s
