- FIGS 3a and 3b a pair of unassembled rubber links, a first pair of links without the application of lateral forces, and a second pair, with the application of lateral forces, which are explained below, are shown in pairs. generated by mounting the links (1) that make up the chain (1 3) around the wheel (14).
- a first link is placed in the 0 position or taking the form of a flat "U".
- a second link is placed in a 180 ° position taking the form of a flattened inverted "U", where the first lateral pillar (3) of said link in a 180 ° position is inserted between the first and second lateral pillars. (3, 4) of the link positioned at 0 o .
- the first projection (5) of the link in 180 ° position is introduced in the first interstitium (7) of the link positioned at 0 o , both links being tongue and groove, as illustrated in Figure 5.
- a third link is placed in the 0 position or taking the form of a flat "U", where the second side pillar (4) of said link in position 0 or, is introduced inbetween the first and second lateral pillars (3, 4) of the link positioned at 180 °.
- the second projection (6) of the link in position of 0 o is introduced in the second interstitium (8) of the link positioned at 180 °, leaving these last two links, also wedged in a tongue and groove.
- the procedure described above allows the links (1) to be curved, according to that shown in figures 12 to 15.
- the links that are positioned at 180 ° taking the form of a flat "U” inverted generate a curved curvature concave (17) on the surface of the lower face (10), which ends at a first end (18) and a second end (19), said concave curve curvature (17) coinciding with the convex curved surface of the wheel (14).
- the links that are positioned at 0 or taking the form of a flat "U” generate a concave curved curvature (20) on the surface of the lower face (10) of the link (1), which ends at a first end (21 ) and at a second end (22).
- the ends (21, 22) allow to generate points oriented towards the ground helping the chain to be inserted in the mud or snow, improving the adhesion to the ground.
- a gap (24) is generated between the peripheral links (1) parallel to the axis of rotation of the wheel (14) which as a surface singularity in the chain (13) improves the adhesion with the ground (23).
- the chain is perimetrically adjusted to the wheel, due to the rubbing of the rubber on its surface.
- the links of the modular rubber chain are obtained with a single rubber profile that has the basic shape of said flat "U”, which is cut according to a desired width as shown in Figure 16.
- an elongated profile is shown which is cut in a plurality of links (1), to a desired width, which will be given by the width of the wheel of the vehicle where the chain will be used.
- first and second projections (5, 6) are formed by a projection of rectangular cross-section and said first and second interstices (7, 8) have the shape of a rectangular cavity.
- first and second projections (5, 6) are formed by a projection of the shape of a dovetail and said first and second interstices (7, 8) have the shape of a cavity homologous to the dovetail of the first and second projections (5, 6), allowing a perfect and tight fit.

- Figures 25 and 26 show a chain (13) installed on the periphery of the wheel (14) and rolling on the ground (23), for example with snow and / or mud, where the ends (21, 22 ) of the links that are positioned at 0 o and that take the form of a flattened "U", insert their tips in the snow and / or mud helping the adhesion of the vehicle to the ground (23).
- the rubber chain for vehicles preferably motorized, has several advantages over the chains of the prior art.
- This chain is easy to manufacture, because it conforms to a single profile that, when cut transversely with the desired equidistance, generates a series of identical links of the required length.
- This chain also allows generating additional damping on the wheel, due to the elasticity of the material, which reduces the impact of the vehicle's shock absorbers.
- the chain of the present invention provides additional protection to the wheel, since any puncture or cutting agent that is on the ground will affect a link and not the tire; This unit element of the chain can be replaced by an identical one.
- this chain has great adaptability, because it adjusts to different wheel diameters by adding or removing links.
- This chain is easy to install, because it can be installed or uninstalled from the wheel, without special tools, using the physical capacity of any person.
- This invention has a wide range of applications, because it can be used in any type of land vehicle with wheels, whether motorized or not, with human or animal traction, where by way of example it can be mentioned: movement machinery dirt, trucks, vans, cars, bicycles, tricycles and carriages.
