Abstract

A spur gear for transmitting a drive torque in a toothing of a motor vehicle transmission is provided, having a helically toothed first gear body for forming first teeth, a second gear body, which is helically toothed oppositely to the first gear body so as to form a herringbone toothing, for forming second teeth, wherein, on axial sides which face toward one another of the first gear body and of the second gear body, the first teeth and the second teeth point toward one another, so as to at least partially overlap one another, in each case pairwise, wherein, on that axial side of the first gear body which points toward the second gear body, a first tooth flank of the first tooth points in an axial direction toward a second tooth flank of a second tooth which follows the opposite second tooth in a circumferential direction.
