Embodiment Construction

[0022] exist figure 1 A drive wheel 10 of a crawler 12 of an agricultural work machine such as a tractor (not shown) is shown. The construction of a crawler-type running gear with elastic tracks will not be described in detail, as this is considered to be known to those skilled in the art. A working machine in the sense of the present invention can also be a construction machine with a crawler-type running gear, or a self-propelled harvester, such as a combine harvester or a forage harvester.

[0023] In order to support the agricultural working machine relative to the ground, the crawler 12 has elastic crawler belts 14 , which are made of rubber, for example, which loop endlessly. The crawler 14 is here driven by a drive pulley 10 , placed in a rotary motion and run by at least one working roller (not shown) and a support roller 16 , at which the crawler 14 is turned, by means of which the working machine can pass Supported relative to the ground. The drive of the crawler ...

Abstract

A driving wheel (10) for a crawler running gear (12) of an agricultural working machine, comprising at least one drive wheel (20, 42) for driving the elastic crawler belt ( 14). According to the invention, the at least one drive wheel (20, 42) has a carrying arm (28) which extends radially in the form of a spoke from the axis of rotation (26) of the drive wheel (20, 42), and At least one gap (34) is formed between two adjacent carrying arms (28) on the radially outer side, and at least one friction element (36) is respectively arranged on the carrying arms (28) on the radially outer side, with The arrangement is in particular releasable for cooperating force-lockingly with the track (14).

Description

technical field [0001] The invention relates to a driving wheel used for a crawler-type traveling mechanism of an agricultural working machine, as well as a crawler-type traveling mechanism and an agricultural vehicle. Background technique [0002] Agricultural work machines, such as tractors or self-propelled harvesters, are becoming larger and more powerful in design to enable more efficient processing of agricultural fields. In this case, as the own weight of the working machine increases, so does the total permissible weight that must be supported on the ground. The high overall weight here often also enables a high ballast of the agricultural work machine, which can be arranged variably on the work machine depending on the work to be performed, for example in order to influence the shift of the center of gravity of the work machine. bit. In order to avoid as far as possible unfavorable ground compaction, the aim here is to increase the bearing surface on the ground, w...
