Embodiment Construction

[0026] figure 1 Shown is a crawler mechanism R, particularly for construction machinery such as a road finisher (not shown), wherein the crawler mechanism R comprises a frame 1 (e.g. edge-mounted steel plates) on which besides tracks for not shown Track rollers and drag chain wheels, not shown, can also be provided with a drive guide wheel (not shown), wherein the track is guided on the guide wheel 2, which provides the track tensioning function in the track mechanism R And the tracks are pretensioned by the tensioning device V, but under impact loads under the force of the tensioning device V are recessed. As an alternative, two or more guide wheels 2 (not shown) placed next to each other can also be provided.

[0027] The guide wheel shaft 3 used in the guide wheel linear guide L1 of the frame 1 guides the guide wheel 2 displaceably in the guide direction F on two parallel block guides 4 here. Each guide 4 bears a sliding pad 6 at least on the upper and lower sides, for ex...

Abstract

In a tracklaying gear with a frame (1) having an idler wheel linear guide (L1) in which at least one guide piece (4) holding the idler wheel axle (3) is movable, and on which a tensioning means (V) of a tensioning device (20) supported in the frame (1) can act in the guidance direction (F), at least one mechanically guided and centered elastomer spring body (25) is installed to bulge under axial compression, such that the spring body can be readjusted, the elastomer spring body consisting of an elastomer material largely incompressible as a spring.

Description

technical field [0001] The invention relates to a crawler according to the preamble of claim 1 or claim 2 of the present application. Background technique [0002] In construction machines, such as road finishing machines in particular, the running gear usually consists of two crawler carriages, each of which has a crawler carriage on one side. The caterpillar comprises a stabilizing frame, in which, besides the track rollers and drag chain wheels and the drive idler, at least one guide wheel and a tensioning device for the caterpillar are arranged. The drive force is transmitted to the drive pulley which, for example, stretches the lower run of the track and keeps it taut. The tensioning device maintains the track with the required tension through the guide pulley. In the case of shock loads, or in the event of clamping objects, the guide wheels are recessed into the tensioner. Different types of tensioning devices can be used. One type of tensioner has a strong flat co...
