Constant velocity joint

A constant velocity joint, comprising:

• a joint outer part having a connecting side configured to connect to a first shaft and an opening side having an opening and a plurality of axially extending race grooves in the opening;
• a joint inner part at least partially located in the opening, the joint inner part including an outer surface having a plurality of axially extending race grooves;
• and
• a plurality of balls between the joint inner part and the joint outer part, each of the plurality of balls being located partly in one of the plurality of race grooves of the joint outer part and partly in one of the plurality of race grooves of the joint inner part,
• wherein a first subset of the plurality of race grooves of the joint outer part and a first subset the plurality of race grooves of the joint inner part includes a first section that follows a first curved path in the axial direction,
• wherein the first subset of the plurality of race grooves of the joint outer part and the first subset of the plurality of raceways of the joint inner part include a second section that follows a second curved path in the axial direction,
• wherein the first curved path has a first curvature and the second curved path has a second curvature opposite the first curvature, and
• wherein the first subset of the plurality of race grooves of the joint outer part and the first subset of the plurality of race grooves of the joint inner part include a linear third section.
