| 摘要 |
The invention relates to a steerable tracklaying unit whose circulating track can be pivoted perpendicularly with respect to the plane of circulation and is guided on a guide frame which has a plurality of frame sections (1) which are connected to one another in an articulated fashion, at least two of which sections (1) can be pivoted with respect to one another about a vertical axis, which extends through the centre of the joint connection (5), and can be secured for the purpose of steering the tracklaying unit by means of a steering device (13). In order to improve the off-the-road properties of such a tracklaying unit, the invention proposes that the track be forceably guided on all sides on the guide frame, that several frame sections (1) have in the longitudinal region of the tracklaying unit drive devices, which drive the track, with engagement elements which engage positively in the track, and that the frame sections (1) be connected to one another in a spacially articulated fashion and have additional steering devices (14) by means of which they can each be pivoted with respect to one another about a horizontal axis which extends through the centre of the joint connection and transversely with respect to the longitudinal extent of the tracklaying unit, and can be locked. <IMAGE>
