Abstract: A military tank with a heavy weapon suspended to pivot in elevation in a turret that rotates on a chassis. The turret (2) is on the rear half (1.2) of the chassis (1) and its drive mechanisms are in the forward half. At least the section of the upper surface (1.2) below the turret slopes back and down at a prescribed angle (.alpha.) to the horizontal. The vertical longitudinal cross-section (LM) of the turret is a wedge that tapers together forward with its bottom (2.1) paralleling the upper surface of the chassis and its top (2.2) at another prescribed angle (.beta.) to the horizontal.

Abstract: An elevating bearing for a large-caliber weapon accommodated in the turret of a tank, with a slant-ring bearing around the tube. The tube is mounted in a bearing ring that rotates around the axis of the tube and is itself mounted on another bearing ring and rotates around an axis at an angle to the axis of the tube. The second bearing ring rotates in the turret around another axis at an angle to the first axis. The angle between the first and the second axes of rotation equals the angle between the first axis of rotation and the axis of the tube. Both bearing rings can be driven around their axes of rotation. The slant-ring bearing is a subassembly inside the turret and the flange that secures the second bearing ring is secured stationary to the turret. The flange that the tube is mounted on and that secures the first bearing ring is secured non-rotating to the turret.

Abstract: An ammunition magazine for stowing large-caliber ammunition in a miltiary tank. The rack has an intake rack comprising rows of essentially horizontal intake tubes positioned one above and next to another for accommodating shells. The rack can be lowered into the tank's ammunition bunker from above. The intake rack is suspended at the top from an antivibration and shock-absorbing suspension on the bottom of an impact-resistant roofing plate that fits into an opening in the roof of the tank and can be locked into the opening along the edge. The rack has at least one centering pin at the bottom that fits into a receptacle on a base secured to the floor of the ammunition bunker when the rack is lowered in.

Abstract: A battletank having a turret with especially heavy armor for containing the weapons system and a crew whereby the minimum possible dimensions of the armor and sufficient space for the crew are achieved, the power supply installations, the electrical and electronic assemblies and the ammunition being located in spaces outside of and behind the crew's space and separated from the latter by protective bulkheads. The ammunition, in order to avoid endangering the crew, is arranged in the ammunition space such that the warheads take effect in a direction opposite to that of the crew's space. In addition, the gun sight and observation devices can be arranged outside of the crew's space. The spaces outside of the crew's space may be accessible from the outside individually through access doors and the weapons system can be retractable for loading into a loading position in which the breech of the weapon is approximately at the same height as a connecting opening between the crew's space and the ammunition space.
