The invention relates to a tracked vehicle () comprising a vehicle body (), at least one track assembly () and a suspension device (S) for suspension of said track assembly () to said vehicle body () of said tracked vehicle (). Said track assembly () comprises a track support beam (), a plurality of road wheels (), at least one drive wheel (), and an endless track (). Said track support beam () is arranged to support said at least one drive wheel () and a plurality of road wheels (). Said endless track is disposed around said at least one drive wheel () and plurality of road wheels (). Said suspension device (S) comprises two pendulum arms () which in one end are rotatably attached to a respective fastening point (P, P) in said vehicle body () and in the other end are rotatably attached to a respective fastening point (P, P) in the track support beam () of said track assembly (). Said suspension device (S) comprises distance adjustment means () which is arranged to allow one or more of: a distance change between said two fastening points (P, P) in the track assembly (); a distance change between the two fastening points (P, P) in the vehicle body (); and a distance change between the fastening point (P, P) in the vehicle body () and the fastening point (P, P) in the track support beam () of said track assembly () of at least one of the pendulum arms (), so as to allow a tilting movement of the track assembly (), including said at least one drive wheel () and plurality of road wheels (), relative to the vehicle body in a plane extending in the longitudinal direction of said track assembly () essentially orthogonal to the transversal extension of said track assembly ().

The invention relates to a tracked vehicle () comprising a vehicle body (), at least one track assembly () and a suspension device (S). Said track assembly () is arranged to be supported by said vehicle body () by means of said suspension device (S), said track assembly comprising a track support beam () for supporting a plurality of road wheels (), an endless track () being disposed around said road wheels. Said suspension device (S) comprises a bogie arrangement () rotatably attached to a fastening point (P) of said vehicle body () about an axis of rotation (Z) transversal to the longitudinal extension of said track assembly () and attached to said track support beam () in connection to at least two fastening points (P, P) so that the track support beam () is allowed to rotate in a rotational plane extending along the longitudinal extension of said track support beam () about said axis of rotation.

The present invention relates to a steering device comprising a steering member for mutually steering a first vehicle unit and a second vehicle unit of an articulated vehicle which comprises a link mechanism for mutually pivoting said vehicle units, a housing configuration arranged to form a supply space between said vehicle units and a removal mechanism arranged in the supply space, wherein the removal mechanism comprises a heating device arranged to heat air intended to stream through the housing configuration. The invention also relates to an articulated vehicle with a steering member.

Steering device for articulated vehicle

The present invention relates to a steering device (I) comprising a steering member () for mutually steering a first vehicle unit () and a second vehicle unit () of an articulated vehicle () comprising means () for mutually pivoting said vehicle units, wherein the steering device comprises a housing configuration () arranged to form a supply space between said vehicle units (), comprising means (, S;, A, O) arranged for removal of stuff in the supply space (S) incoming from the surrounding. The invention also relates to an articulated vehicle with a steering member.

An arrangement for the steering and coupling together of two associated tracked units to form an articulated tracked vehicle set, includes a first upright for releasable coupling to a fixture on one of the tracked units, a second upright for coupling to a fixture on the other tracked unit, a first steering link which is connected in an articulated manner to the first upright about a first horizontal axis and a second steering link which is connected in an articulated manner to the second upright about a second horizontal axis, parallel with the first horizontal axis. The first and second steering links are mutually joined to a steering link unit about a steering pivot with a vertical axis of articulation. Hydraulic ram cylinder units are arranged so as to control relative turning movements between the first upright and the steering link unit, between the second upright and the steering link unit, and between the first and second steering links. The first upright is formed so as to be able to be anchored rigidly in one of the tracked units while the second upright is formed so as to be capable of rotation in bearings in the fixture on the other tracked unit about a longitudinal horizontal axis.
