The irfir., Dving looks at / tin drive wheels for liaupcn-, |

Fahraeuge in particularly heavy soils such as a.3. Iiu'r.m ^ S

difficulties arise again and again that s: .ch the f

Adding stones and clay to chains, the interlocking of the
Drive wheels cannot fully engage in the chains
and that the teeth of the drive wheels do not grip the ..- oil bushings and spin.

By spinning (climbing>. ~ R chains) arise
very quickly large damage to äe.-τ entire drive _t because
the load on the individual drive parts is far higher than
is at a normal load.

To counteract this ascent of the chains. work is a spring-loaded chain tensioner οϊη ^ ο-builds in every drive. Through this chain tensioner, the idler wheel opposite the drive wheel is cushioned and thus allows the KöttGn ZU _{1 to} rise because if this idler wheel were not cushioned, the Kotton would tear, or other drive wheels such as AntriobcachGu »Gotriobo etc. would be destroyed.

In the case of the previously known drive wheels, as with everybody. Sprocket the teeth of the drive wheel between oils Chain sleeves. For all tracked vehicles, abor not only the chain pulling force that drives the dop machine required is transmitted through the bushings of the chains, but the entire weight of the vehicle is available on these chain sleeves. It is therefore understandable that through the cooperation of three forces.

Machine weight,
Chain pulling force,
additional pulling force when climbing the chains,

very high loads occur, which often lead to chain breaks, or broken bushings.

/ · Λο The patent pending drive wheel which is also known as \. The idler wheel can be used, prevents in the design according to Figs. 1 and 2) the chains from rising through dirt or stones, especially the bushings of the chains not as with the previously known drive wheels ran into a tooth gap, but always lie in front of or behind a tooth. It is therefore not possible to fix the dirt in a tooth gap because there is no longer any tooth gap. The sprocket shown i .. .-. "00. 1 and 2) also has the advantage,

that the chain bushings are not in the tooth base of the drive wheel, as is the case with the previously known chain wheels and must therefore bear the weight of the machine in addition to the chain pulling force. Both in Fig. 1 and 2) shown sprockets are the Bushings completely free because the chain links rest on the side flanges of the drive wheel come.

These drive wheels, for which a patent is pending, can also be used as idlers, but have the advantage over the previous idlers that the chain is no longer of the idlers, which have a relatively low flange of approx. have to jump off. The teeth of the drive wheels, for which a patent is pending, engage much higher in the chain and thus prevent it from jumping off.

Basically, the benefit would be the * new patent registered drive wheels to say:

As with the previously known drive wheels, the chains cannot ascend when driving in dirt and stones.

The / are veötenbüchsen only, the hoist and not burdened by the weight of the machine _T because the cans not line in the tooth root of the sprockets ^ but the chain links on the outer flanges of the patent pending drive wheels, fig. 1 and 2 rest).
