FIXED, CONSTANT VELOCITY BALL JOINT HAVING A GREAT DEFLECTION ANGLE

摘要

Fixed, constant velocity ball joint 11 comprising a joint outer part 12 having outer ball tracks 21, a joint inner part 16 having inner ball tracks 22, torque-transmitting balls 25 which are guided in track pairs comprising outer ball tracks 21 and inner ball tracks 22, and a ball cage 27 having cage windows 28 which are distributed over the circumference and in which the balls 25 are held together in the joint centre plane E when the joint is extended and are guided in each case onto an angle-bisecting plane when the joint is deflected, having at least one joint opening 15 of the joint outer part 12, which joint opening 15 forms an annular stop face 29, and having a shaft 18 which penetrates the joint opening 15 and is connected to the joint inner part 16, and comes into contact with the annular stop face 29 at a maximum operating deflection angle ßmax of the joint, wherein the generatrices of the shaft 18 which come into contact with the annular stop face 29 produce an opening cone, wherein, at a maximum operating deflection angle ßmax of the joint, in each case at least one ball 25 exits the outer ball track 21 at the joint opening 15 of the joint outer part 12 to such an extent that the centre point K of the ball 25 is at an axially parallel spacing L₁ from the joint centre plane E and is at an axially parallel spacing L₃ from the opening cone, wherein L₁/L₃ is smaller than 2.9.
