Abstract

A compensation shaft for a multi-cylinder engine at least two bearing pegs and at least four unbalanced weight sections, two of the at least four unbalanced weight sections being arranged respectively, around each of the at least two bearing pegs, so that at least two units are formed, these at least two units being connected to each other by a connecting part, wherein two of the unbalanced weight sections are arranged asymmetrically around each of the two bearing pegs, and the connecting part is configured as a flexurally rigid and torsion-proof component.

Claims (4)

1. A compensation shaft for a multi-cylinder engine, said compensation shaft comprising at least two bearing pegs and at least four unbalanced weight sections two of the at least four unbalanced weight sections being arranged respectively around each of the at least two bearing pegs, so that at least two units are formed, these at least two units being connected to each other by a connecting part, wherein two of the unbalanced weight sections are arranged asymmetrically around each of the two bearing pegs, and the connecting part is configured as a flexurally rigid and torsion-proof component in form of a rectangular cross-section oriented in direction of the unbalanced weight sections.

2. A compensation shaft for a multi-cylinder engine, said compensation shaft comprising at least two bearing pegs and at least four unbalanced weight sections two of the at least four unbalanced weight sections being arranged respectively around each of the at least two bearing pegs, so that at least two units are formed, these at least two units being connected to each other by a connecting part, wherein two of the unbalanced weight sections are arranged asymmetrically around each of the two bearing pegs, and the connecting part is configured as a flexurally rigid and torsion-proof component.

3. A compensation shaft for a multi-cylinder engine, said compensation shaft comprising at least two bearing pegs and at least four unbalanced weight sections two of the at least four unbalanced weight sections being arranged respectively around each of the at least two bearing pegs, so that at least two units are formed, these at least two units being connected to each other by a connecting part, wherein two of the unbalanced weight sections are arranged asymmetrically around each of the two bearing pegs, and the connecting part is configured as a flexurally rigid and torsion-proof component.

4. A compensation shaft for a multi-cylinder engine, said compensation shaft comprising at least two bearing pegs and at least four unbalanced weight sections two of the at least four unbalanced weight sections being arranged respectively around each of the at least two bearing so that at two units are formed, these at least two units being connected to each other by a connecting part, wherein two of the unbalanced weight sections are arranged asymmetrically around each of the two bearing pegs, and the connecting part is configured as a flexurally rigid and torsion-proof component.
