Abstract
A constant velocity joint having an inner hub and an outer hub (1) in which races or tracks (3) associated with one another in pairs are provided and with balls received in respective pairs of races or tracks for transmitting torque. The constant velocity joint is further provided with at least one joint connector (2) which, when the joint is assembled, is connected in a rotationally fixed manner to one of the hubs (1) by mating profile members (6, 7) in order to transmit torque.
Claims7
In a constant velocity joint comprising
- an inner hub and
- an outer hub,
- wherein said inner hub and said outer hub are each provided with a plurality of tracks, with tracks of said inner hub being associated in pairs with respective tracks of said out hub, and
- with balls received in respective pairs of tracks for transmitting torque between the inner hub and the outer hub,
- said joint further comprising at least one joint connector which, when the joint is assembled, is connected to the outer hub via mutually associated interengaging profiles on said outer hub and on the joint connector for transmitting torque,
- the improvement comprising:
- said interengaging profiles being constructed such that, when the joint is assembled, said outer hub is connected to the joint connector in a rotationally fixed manner by a press fit in at least the circumferential direction, and
- the interengaging profiles being constructed such that during assembly of the joint, the joint connector is displaceable along a displacement path relative to the hub, with the joint connector being readily displaceable with a clearance relative to the hub along a first portion of said displacement path, and
- said joint connector being connected to the hub with a press fit for rotational fixation only along a terminal portion of said displacement path.
