Abstract
Constant-velocity ball joint, having at least a joint outer part with an axis of rotation and with outer ball tracks and with outer center lines, a joint inner part with inner ball tracks and inner center lines, and a large number of torque-transmitting balls which are each guided in mutually associated outer ball tracks and inner ball tracks.
Claims12
A constant-velocity ball joint, comprising:
- a joint outer part with an axis of rotation and with outer ball tracks and with outer center lines;
- a joint inner part with inner ball tracks and inner center lines, and
- a plurality of torque-transmitting balls which are respectively guided in mutually associated outer ball tracks and inner ball tracks;
- wherein, in a straight arrangement of the constant-velocity ball joint, the outer center lines run at a constant spacing from the axis of rotation;
- wherein the joint inner part and the inner center lines extend along the axis of rotation between a first front side and a second front side, and at least one of the inner center lines extends between a first end present at the first front side and a second end present at the second front side and runs at a varying second spacing from the axis of rotation;
- wherein a maximum value of the second spacing is arranged at a distance from the first end and the second end, and wherein the constant-velocity ball joint is a plunging joint with the joint inner part being displaceable along the axis of rotation and relative to the joint outer part by at least 5 millimeters.

- a joint outer part with an axis of rotation and with outer ball tracks and with outer center lines;
- a joint inner part with inner ball tracks and inner center lines, a plurality of torque-transmitting balls which are respectively guided in mutually associated outer ball tracks and inner ball tracks;
- and
- a cage which is provided with a large number of cage windows which each accommodate one or more of the balls;
- wherein, in a straight arrangement of the constant-velocity ball joint, the outer center lines run at a constant spacing from the axis of rotation;
- wherein the joint inner part and the inner center lines extend along the axis of rotation between a first front side and a second front side, and at least one of the inner center lines extends between a first end present at the first front side and a second end present at the second front side and runs at a varying second spacing from the axis of rotation;
- wherein a maximum value of the second spacing is arranged at a distance from the first end and the second end, and wherein the constant-velocity ball joint is a plunging joint with the joint inner part being displaceable along the axis of rotation and relative to the joint outer part, and
- wherein the cage is guided with a spherical inner circumferential surface over a spherical outer circumferential surface of the joint inner part.
