<p>For a cannon movable by means of a traction vehicle (9) and comprising an upper mount (18) and a lower mount (1) comprising the running wheels (16) and being designed as a swivelling bolster, two spars (2,3) are hingedly connected to the lower mount (1) and are interconnected at their ends remote from the lower mount (1) by a supporting rod (4) for forming a four-bar mechanism. One of said both spars (2,3) carries at its end remote from the lower mount (1) a limber rod (6) having its free end located approximately in the vertical longitudinal center plane of the four-bar mechanism and carrying the trailer coupling. For steering the lower mount (1) carrying the running wheels (16), a control mechanism capable of being put in operating connection with the traction vehicle (9) is provided. Said control mechanism can be formed of a strut rod (5) crossing, seen in a top plan view, the limber rod (6) and having one end hingedly connected to the spar (3) carrying the limber rod (6) and having its other end capable of being hingedly connected to the traction vehicle (9) at a lateral distance from the trailer coupling of the traction vehicle. For aligning the gun barrel (12) in an approximately parallel relation to the spars (2,3), a holding device for a gun barrel (12) is arranged on at least one of both spars (2,3).</p> |
