"Endless track belt, especially for caterpillar vehicles"

The invention relates to an elastic material consisting of endless track belt, especially for caterpillar vehicles, which is suitable for caterpillar vehicles traveling at higher speeds, and for driving on polygons, yielding and very uneven terrain suitable «'.

As is well known, in most of the track bands made of elastic material it is assumed that, in addition to the elastic bands, support and transmission elements made of steel will also be used. ¹

For example, vehicles were equipped with track belts, on whose treads a link chain attached to non-insole Gumiui is attached, the length of which between two treads is greater than that of the corresponding section of the unloaded Guinmigleisband. ¹ The chain on the rubber band should ensure that the bending stresses exerted on the rubber are absorbed by the chain if they reach a level that is not permissible for the GunLai support the 'frennfugen extending over the entire width of the belt between the gripper points of the longitudinally elastic treadmill and are each individually firmly connected to a guide member, independent of adjacent similar guide members, with the drivers at their ends forming driver teeth, which with teeth of the l 'Rifle wheels engage.' The solutions with the known track strips have the disadvantage that they are forced to use steel link chains, for example, in order to avoid unwanted elongation, for example, so that they are severely restricted in their ability to flex. '

Another disadvantage arises, as well as with elastic Track belts with screwed-on drivers and guides made of steel, that by, the unnecessarily heavy belts in their üinsabz large circulating masses arise, which by their Uhwue-ht dan hinder the folding stuff at its maximum speed and also lead to a great deal of wear and tear on the chassis itself. '

The purpose of the invention is therefore to "restrict the functionality of the tracks" Means as well as the high loads on the chassis to "eliminate". The object of the invention is to create a flexible track strip made of elastic material with which high tensile forces and good hatching behavior is achieved without a Elongation occurs during use and without the use of metal transmission elements. " According to the invention this is achieved in that the inner pre-tensioned core of a track strip made of elastic material, which is made of polyamide or material similar to fabric Properties is made, consists of an inner and outer core part. Both core parts are spaced from one another Rubber not separated from each other. J> he inner biased The core part is shorter than the outer key part, which is also vorgespanij.ee. This creates a higher tensile stress between the supporting wheels and the length of the track on the ground the inner core part to the outer core part, so that inevitably a bulging effect arises. To apply only of a pre-stressed core part the same arching effect between To achieve the supporting wheels, steel profile pieces are between the pieces that are pulled together by the pretensioning of the core Pressed gripper cleats on the bottom. The invention is intended below using an exemplary embodiment are explained in more detail, 'In the accompanying drawings: Fig. 1: Scheme of the track with the identification of the

Since the inner core part is shorter than the outer core part, arises as shown in ¥ 'ig, 1 ;, between the supporting wheels 5; 6; 7 the track strip length stretched at the bottom a higher 2! _U tension of the inner core part 2 to the outer core part 3 and thus a bulging effect. Due to the curvature 8 of the band ¥ / ird the load-bearing track area under the traveling gear wheels is enlarged. The result is a lower specific ground pressure and an improved traction-slip-Yerhalt. If only one core is used, according to "EIg, 3 the possibility of the same vaulting effect between the supporting Eahrwerkwheels by means of pressed-in profile pieces 10 'can be achieved, since the gripper lugs 11 when only one core is used strive to contract _c

Claims (1)

1V80857 Claims Endless track tape, which is made of elastic material and its inner core made of polyamide or material with fabric-like properties for the purpose of avoidance is pretensioned by elongation that occurs under normal operating loads, especially for caterpillar vehicles, characterized in that the core consists of an inner and an outer core part (2; 3) and both core parts (2} 3) through a spacing & remixing layer (4-) are separated from each other, wherein the inner prestressed core part (2) is shorter than the outer also prestressed Core part (3)> so that in each case the length of track on the bottom side between the supporting Chassis wheels (5; 6j 7) a higher tensile stress of the inner core part (2) to the outer core part (3) and thus arching effects inevitably arise » Endless track strip according to claim 1, characterized in that when only one pretensioned core (9) is used by means of profile pieces (10) made of steel, for example, which are located between the prestressing generated by the of the core (9) contracted bottom gripper cleats (11) are pressed in, the arching effect between the supporting gear wheels u G; 6; 7) arises.
