FR2598355A1 - Device for getting land vehicles out of the sand - Google Patents

Abstract

The subject of the present invention is a device for getting land vehicles out of the sand. It is characterised by runners mounted on different types of supports connected to the wheel by slides, chains or other forms of tensioners. By extension, this device makes it possible to produce a rotary caterpillar track.

Description

 The present invention relates to a device allowing all land vehicles to get out of sandy, marshy, muddy, slippery areas, etc. By extension, this device makes it possible to produce a rotary track.

 Devices to get out of critical areas where the wheels of vehicles sink or slip, only the conventional track fitted to 165 public works or army vehicles is effective but not adaptable at the appropriate time on the wheels of vehicles in difficulty .

 The object of the present invention is to provide a simple, robust device, very reliable and above all very easily adaptable to any wheel on land vehicles.

 To this end, the present invention relates to a device adaptable to the driving wheels of the vehicle by simple adaptation and fixing of sets of slides, chains or other tensioners.

 The process of the desensitization device consists in producing a solid and mobile surface as the wheel moves. This device is efficient and reliable due to the pivoting at the axis of the arched shoe varying according to the diameter of the wheel.

 The present invention is characterized by an articulated triangle (1), adjustable for adaptation to different diameters of wheels supporting the pads (2) movable on axis (3), connected to the inside of the tire by closures with chains or the like and d '' a skate which can be made of steel, aluminum, rubber, plastic, new or composite materials of different sizes and surface depending on the nature of the machine (passenger vehicles, heavy goods vehicles, public works, agricultural, army etc ... ) and receive a non-slip, ridged, dimpled structure, etc.

 In addition, in this invention, the skate provides a bearing surface for the 801 constant Qrace at its angular or curved shape allowing it to remain in permanent contact with the vehicle tire during its axis displacement (A-B).

 By extension, this desensitization device can, by means of a special construction for adaptation of the shoe on the entire circumference of the wheel, thanks in particular to the shape of the shoe and its action, become a rotary track (fig3), hence many uses in the damines of agricultural public works, etc ...

The adaptation of the device allowing to increase the traction and the thrust of any tire machine.

 Of course, the present invention is not limited to the embodiment described above, but covers all variants thereof. The pads can also be mounted on any other form of support.

Claims (4)

R E V E N D I C A T I O N S  1. Device for desensitization adaptable on wheels characterized by pads mounted on different forms of supports and connected to the wheel by different sliding systems, chains or other forms of tensioners, allowing besides the design to multiply and relax this device to all kinds vehicles such as passenger vehicles, public works machinery, agricultural tractors, heavy goods vehicles among others.  2, Device according to claim I characterized in that the movable part of saconception share (Fig 4) allows movement of the vehicle by the ascent of the wheel on the pad qans that it does not move during the rise st of the lowering of this rouo and ceoi by offset of the axis of the wheel relative to the shoe (Fig 4 A + M)  3. Device according to claim 2 which by multiplying the pormet pads to achieve a rotary track.  4. Device according to claim 3, characterized in that the pad or pads on which the wheel is driven at an angle or a curvature and a beam made up of various and multiple materials whether they are inter-skid or not.
