Driving wheel for crawler-type walking mechanism

Abstract

The invention discloses a driving wheel (10) for a crawler-type walking mechanism (12) of an agricultural working machine. The driving wheel includes at least one driving wheel (20, 42) for driving elastic crawlers (14) of the crawler-type walking mechanism (12). According to the driving wheel, the at least one driving wheel (20, 42) is provided with bearing arms (28), the bearing arm extends in aradial direction from a rotation axis (26) of the driving wheel (20, 42) in a spoke manner, gaps (34) are formed outside the radial direction and at least between the two adjacent bearing arms (28),and at least one friction element (36) is arranged on the bearing arm (28) and outside the radial direction correspondingly for combined acting with the crawlers (14) in a force closure manner. The arrangement is carried out in particular in a manner of capable of be loosened.

Description

technical field

[0001] The invention relates to a driving wheel for a crawler-type traveling mechanism of an agricultural working machine, a crawler-type traveling mechanism and an agricultural vehicle. Background technique

[0002] Agricultural work machines, such as tractors or self-propelled harvesters, are being designed increasingly larger and more powerful in order to allow more efficient processing of agricultural fields. In this case, the permissible total weight that must be supported on the ground increases as the dead weight of the working machine increases. The high overall weight often also enables a high ballast of the agricultural work machine, which, depending on the work to be performed, can be arranged variably on the work machine, for example in order to influence the displacement of the center of gravity of the work machine. bit. In order to avoid as far as possible unfavorable ground compaction, the aim is to increase the bearing surface on the ground,...
