Device for relieving the load on rollers

The innovation relates to a device for relieving the rollers of a drive on tracked vehicles via support elements, the rollers via spring-loaded swing arms on the armored hull are arranged and guided over a track running on the floor.

There are already known devices consisting of a support arm, on the one hand in the crawler belt is anchored and on the other hand grasps obliquely under the bearing of the corresponding roller. By the movement of the tracked vehicle is then placed by the support arm between the roller bearing and the crawler vertically and thus presses the roller into a relieved position.

This known device has the defect that a damaged roller must be replaced and thus the vehicle will not be ready for operation again in a short period of time. In the event of damage to the roller bearing A complete repair is still required and the spare parts are usually not available for this. Furthermore, it has been shown in practice that this is to be erected Support arms do not offer any functional safety in the field and can relatively easily lead to accidents.

The task of the innovation is to provide a simple, functionally reliable To create device of the generic type and in addition to the Replacing a damaged roller also means switching off a damaged roller to restore a fast one To enable driving readiness as well as one for field use to ensure appropriate implementation.

The solution to this problem is achieved according to the invention by that a drive-on block can be connected via bolts to the inside of the crawler belt to raise a roller and the roller can be locked in the raised position via holding elements.

In this way, a functionally reliable relief of the damaged roller is brought about, also for the first and last Castors can be used and it is not necessary to relax the crawlers. With such a training it is This makes it possible to relieve a damaged roller to make it ready to drive to the repair site.

A simple arrangement is created in that the drive-on block designed in two parts and on both sides

-S-

arranged by, central guide teeth of the crawler as well as can be fixed via socket pins between the central guide teeth.

In order to enable easy handling, it is proposed that the holding elements are provided with brackets are formed, which can be used between receptacles or on the armored hull and the rollers.

f It is also provided that the drive-on block from

Light building materials such as hardwood, aluminum or ^ ^{N the} like. Is formed.

In the drawing, an embodiment of the innovation is shown schematically. Show it:

1 shows part of a drive with an inserted drive-on block;

2 shows a roller in the raised and locked position;

Fig. 3 shows a roller in the ready-to-drive

& elevated location.

^ 'In the training shown are on a tank

tub 1 rollers 2, 3 and 4 arranged via associated swing arms 5, 6 and 7. The rollers 2, 3 and 4 are guided on the floor 9 via a crawler belt 8. Above the rollers 2, 3 and 4 are corresponding Recordings in the form of spring stops 10 or rigid stops 11 on a side wall of the Armored hull 1 arranged stationary.

A two-part drive-on block 12 is inserted between the roller 2 and the roller 3, both of which Parts outside and inside next to center guide teeth 13

the crawler belt 8 and are connected by a socket pin 14 so that the Drive-on block 12 prevented from slipping within the crawler belt 8 by the central guide teeth 13 will.

If the damaged roller 3 is to be relieved, the vehicle is moved in the direction of arrow 15 after inserting the drive-on block 12 moved so far, until the roller 3 has reached the top of the drive-on block 12 as shown in FIG. In this position a bracket 16 is hung on the spring stop 10 and with its lower eyelet over a shaft extension 17 touched the roller axle »If the vehicle is moved again so that the drive-on block 12 is released, the bracket 16 prevents the roller 3 from springing back. It thus remains a raised one Position of the roller 3 exist, and it is either possible to replace the roller on site, or it can be left in the raised position while driving to the nearest repair shop will.
