A joint yoke (7, 107) for a universal joint (2) has a first yoke arm (11, 111) and a second yoke arm (12, 112). The first and second yoke arms (11, 12) have at least two recesses (33, 33′, 34, 34′). The yoke arms (11, 12, 111, 112) have, radially to the axis of rotation (X), an outer portion (A) and an inner portion (B) adjacent to the outer portion (A). The wall thickness (d1) of the yoke arms (11, 12, 111, 112), in a radial direction to the bearing axis (Y) in a plane orthogonal to the axis of rotation (X) and through the joint center (M), is reduced in the outer portion relative to the inner portion (B). |

1. A joint yoke for a universal joint, the joint yoke being rotatably drivable around an axis of rotation, the joint yoke comprising:
a first yoke arm with a first bearing bore; and a second yoke arm with a second bearing bore, the first bearing bore and the second bearing bore being arranged centered on a bearing axis, the bearing axis intersecting the axis of rotation at a right angle at a joint center, wherein the first and second yoke arms, radially to the axis of rotation, include an outer portion and an inner portion adjacent to the outer portion, wherein a wall thickness of yoke arms, in a radial direction to the bearing axis in a plane orthogonal to the axis of rotation and through the joint center, is reduced in the outer portion relative to the inner portion, and wherein the first and second yoke arms have at least two recesses that are arranged at opposite sides of the respective bearing bore, the recesses being arranged at least partially parallel to the axis of rotation. |
