Abstract

The invention relates to a sabot ( 1 ) which comprises multiple sabot segments ( 1.1, 1.2, 1.3 ). The sabot ( 1 ) or the sabot segments ( 1.1, 1.2, 1.3 ) are characterized by having a structural design at an end ( 10 ) opposite the shooting direction such that a low degree of flexural rigidity is achieved at said end ( 10 ). A sabot ( 1 ) with three sabot segments ( 1.1, 1.2, 1.3 ) is preferred. The sabot ( 1 ) or the sabot segments ( 1.1, 1.2, 1.3 ) have a rear part ( 3 ) as a push part and a front part ( 4 ) as a pull part. In order to optimize the shape and weight, the front part ( 4 ) and the rear part ( 3 ) have recesses ( 5, 6 ) in the sabot ( 1 ) or in the sabot segments ( 1.1, 1.2, 1.3 ). Braces ( 8, 9 ) are integrated between the recesses ( 5, 6 ), or the recesses ( 5, 6 ) are introduced between braces ( 8, 9 ).

First claim

What is claimed is:

1. A sabot having a push-pull function, comprising:
a plurality of sabot segments adjacent in a circumferential direction, each of the plurality of sabot segments comprising:
a front push-part;
a rear pull-part;
a pressure flange between the front push-part and the rear pull-part;
a front end arranged in a shooting direction of the sabot;
a rear end arranged opposite to the shooting direction,
wherein the sabot and the plurality of sabot segments has a structural design at the rear end such that the sabot has a low flexural resistance,
wherein the sabot has a cylindrical-shaped portion at the rear end such that the plurality of sabot segments are configured to roll during detachment,
wherein the rear pull-part has a first proximal end proximal to the pressure flange and a second distal end distal from the pressure flange, the second distal end of the rear pull-part being disposed at the rear end of the sabot, the second distal end of the rear pull-part having a thinner wall thickness than the first proximal end of the rear pull-part, the second distal end of the rear pull-part having the thinner wall thickness forming the cylindrical-shaped portion,
wherein the rear pull-part and the front push-part have recesses, the recesses extending along the rear pull-part from the pressure flange toward the rear end of the sabot and the recesses extending along the front push-part from the pressure flange toward the front end, which are open radially outwards, within the sabot segments, the recesses being delimited in the circumferential direction by struts extending in the shooting direction between the rear end and the pressure flange and between the front end and the pressure flange.

2. The sabot according to claim 1 , wherein the sabot comprises at least two sabot segments.

3. The sabot according to claim 1 , wherein the sabot comprises three sabot segments.

4. The sabot according to claim 1 , wherein the sabot has pockets which are integrated in the front push-part.

5. The sabot according to claim 1 , wherein the material of the sabot is plastic, aluminum or the like.

6. An ammunition having a sabot according to claim 1 .

7. The ammunition according to claim 6 , wherein the ammunition in caliber is 105 mm.

8. The ammunition according to claim 6 , wherein the cylinder shape can lie within the last 20 mm to 30 mm of the sabot.

9. The ammunition according to claim 7 , wherein the wall thickness can be approximately 3.5 mm to 4.5 mm.

10. The sabot according to claim 1 , wherein the struts extend along the rear pull-part from the proximal end of the rear pull-part toward the distal end of the rear pull-part and end at a position before the cylindrical-shaped portion.

11. The sabot according to claim 1 , wherein the struts do not extend into the cylindrical-shaped portion.

12. A sabot, comprising:
a plurality of sabot segments adjacent in a circumferential direction, each of the plurality of sabot segments comprising:
a front push-part;
a rear pull-part;
a pressure flange between the front push-part and the rear pull-part,
wherein the rear pull-part and the front push-part have recesses, which are open radially outwards, within the sabot segments, the recesses being delimited in the circumferential direction by struts extending in a shooting direction between a rear end of the rear pull-part and the pressure flange and between a front end of the front push-part and the pressure flange, in the front push-part, the recesses extending from the pressure flange along the front push-part to an end of the front push-part and in the rear pull-part, the recesses extending from the pressure flange along the rear pull-part to an end of the rear pull-part,
wherein the plurality of sabot segments has a cylindrical-shaped portion at the rear end, the cylindrical-shaped portion having a low flexural resistance configured to roll during detachment of the plurality of sabot segments.

13. A sabot having a push-pull function, comprising:
a plurality of sabot segments adjacent in a circumferential direction, each of the plurality of sabot segments comprising:
a front push-part arranged in a shooting direction of the sabot;
a rear pull-part arranged opposite the shooting direction of the sabot; and
a pressure flange between the front push-part and the rear pull-part, wherein the front push-part has a first proximal end proximal to the pressure flange and a second distal end distal from the pressure flange, and the rear pull-part has a first proximal end proximal to the pressure flange and a second distal end distal from the pressure flange, the second distal end of the rear pull-part having a thinner wall thickness than the first proximal end of the rear pull-part,
wherein the sabot has a cylindrical-shaped portion at the second distal end of the rear pull-part, the cylindrical-shaped portion being formed by the second distal end of the rear pull-part having the thinner wall thickness configured to roll during detachment of the plurality of sabot segments, and
wherein the rear pull-part and the front push-part have recesses, which are open radially outwards, within the sabot segments, the recesses being delimited in the circumferential direction by struts extending in the shooting direction between a rear end of the sabot and the pressure flange and between a front end of the sabot and the pressure flange, in the front push-part, the recesses extending from the pressure flange along the front push-part to the second distal end of the front push-part and in the rear pull-part, the recesses extending from the pressure flange along the rear pull-part to the second distal end of the rear pull-part.
