Patent ID: 7758433

Claim:
A joint assembly comprising: a secured type constant velocity universal joint, a slide type constant velocity universal joint, and substantially cylindrical elastomer unit covers; said secured type constant velocity universal joint including one outer joint member formed with a plurality of curved and axially extending first track grooves on its inner circumference, a joint inner ring formed, on its outer circumference, with second track grooves opposite to the first track grooves, torque transmitting balls contained within ball tracks formed by said first and second track grooves, a cage for rollably holding the torque transmitting balls within the ball tracks, a drive shaft with one end connected to the joint inner ring, and a boot mounted on the drive shaft and on an outer circumference at an opened side of said one outer joint member; said slide type constant velocity universal joint including a boot mounted on said drive shaft and on an outer circumference at an opened side of an outer joint member; and said unit covers having reduced diameter portions and being mounted on the outer circumferences of both the constant velocity universal joints; each of the unit covers is formed as two parts divided along a parting plane including its axis and has radially extending flat abutting surfaces on the parting plane, and fastening portions formed on the abutting surfaces and adapted to be engaged, via a elastic deformation of them, so that the unit covers are detachably mounted on both the constant velocity universal joints.
