Tripod joint

Abstract

A ball body is guided in a partially cylindrical hole into which a guide ring is inserted to secure it axially and to guide the pivoting movement. The tripod joint is suitable for the displaceable and pivotable driving connection of two shaft ends, in particular in conjunction with drive trains or side shafts of motor vehicles.

1 . A tripod joint for transmitting a driving torque between two driving elements of a drive train, comprising: 
 a joint inner part; and    a joint outer part holding the joint inner part, the joint inner part having a tripod star including ball bodies with pins, the ball bodies in each case mounted in a recess in a pressure body pivotable with respect to the pressure body, the pressure body and a rolling body configured to transmit the driving torque to the joint outer part, the recess in the pressure body including a cylindrical subregion, at least one guide ring inserted into the pressure body in a region of a cylindrical subregion, a ball body supported with respect to the pressure body via the guide ring.    
     
     
         2 . The tripod joint according to  claim 1 , wherein the recess includes a subregion corresponding to a cutout from a hemisphere and a cylindrical subregion, a guide ring arranged in the cylindrical subregion.  
     
     
         3 . The tripod joint according to  claim 1 , wherein the recess includes a cylindrical hole, two spaced apart guide rings inserted into the cylindrical hole.  
     
     
         4 . The tripod joint according to  claim 1 , wherein the guide rings include a curved and smooth cross-section at least in a region facing the ball body.  
     
     
         5 . The tripod joint according to  claim 1 , wherein the cylindrical subregion includes grooves, the guide rings inserted into the grooves.
