Patent ID: 8714293

Claim:
A constant velocity joint for transmitting rotation between a first shaft and a second shaft, comprising: an outer housing rotatable about a first rotation axis, the outer housing being adapted to be connected to the first shaft, the first rotation axis being coaxial with the first shaft, the outer housing having an inner surface and an outer surface; an inner race rotatable about a second rotation axis, the inner race being disposed inside the outer housing and spaced therefrom, the inner race being adapted to be connected to the second shaft, the second rotation axis being coaxial with the second shaft; the outer housing and inner race being movable relative to one another to change an angle between the first axis and the second axis of rotation; a cage disposed between the outer housing and the inner race; a plurality of balls held between the outer housing and the inner race so that rotation of one of the outer housing about the first rotation axis and the inner race about the second rotation axis causes rotation of the other of the outer housing about the first rotation axis of rotation and the inner race about the second rotation axis, each of the plurality of balls being retained in a corresponding cage window defined through the cage so as to roll along a corresponding one of a plurality of outer housing grooves and a corresponding one of a plurality of inner housing grooves, each outer housing groove being defined on the inner surface of the outer housing, each inner race groove being defined on an outer surface of the inner race; a cooling member fitted onto the outer housing, at least a portion of the outer surface of the outer housing being in contact with the cooling member; and a flexible boot having: a first end portion of the flexible boot being removably attached to the outer housing at a portion of the outer surface extending outside the cooling member, and a second end portion of the flexible boot, opposite to the first end portion, being adapted to be removably attached to the second shaft.
