Patent ID: 7637818

Claim:
Opposed path joint, which has a drive-side end ( 2 ) and a power-take-off-side end ( 3 ), having an inner hub ( 4 ) that has an inner hub axis ( 9 ) and an outer surface ( 11 ), in which first inner grooves ( 12 ) and second inner grooves ( 13 ) are arranged, alternately distributed about the inner hub axis ( 9 ), whereby the first inner grooves ( 12 ) run from the drive-side end ( 2 ), proceeding in the direction towards the power-take-off-side end ( 3 ), and their track base ( 14 ) moves away from the inner hub axis ( 9 ), and whereby the second inner grooves ( 13 ) run from the power-take-off-side end ( 3 ), proceeding in the direction towards the drive-side end ( 2 ), and their track base ( 15 ) moves away from the inner hub axis ( 9 ), an outer hub ( 7 ) that has an outer hub axis ( 16 ) and an inner surface ( 17 ) in which first outer grooves ( 18 ) and second outer grooves ( 19 ) are arranged, alternately distributed about the outer hub axis ( 16 ), and the first inner grooves ( 12 ), in each instance, lie opposite first outer grooves ( 18 ), and the second inner grooves ( 13 ) lie opposite second outer grooves ( 19 ), and form a pair with them, in each instance, whereby the first outer grooves ( 18 ) run from the drive-side end ( 2 ), proceeding in the direction towards the power-take-off-side end ( 3 ), and their track base ( 20 ) comes closer to the outer hub axis ( 16 ), and whereby the second outer grooves ( 19 ) run from the power-take-off-side end ( 3 ), proceeding in the direction towards the drive-side end ( 2 ), and their track base ( 21 ) comes closer to the outer hub axis ( 16 ), in this connection, a ring-shaped cage ( 5 ) having a spherical outer surface ( 36 ), which cage is arranged between the inner hub ( 4 ) and the outer hub ( 7 ) and has radial openings ( 37 ), corresponding to the number of pairs of grooves ( 12 , 18 ; 13 , 19 ), in which balls ( 6 ) that engage in the grooves ( 12 , 13 ; 18 , 19 ) are guided, wherein the outer hub ( 7 ) is a single-piece closed ring.
