Claims14
An apparatus for sealing a ball joint of a kingpin, comprising:
- a socket formed by a wall forming a first circumference around a recess for receiving the ball joint, the wall extending in the direction of a center axis of the recess;
- at least one holding ring formed in two pieces and extending from the first circumference toward the center axis of the recess, and a holding ring end face positioned at a second circumference radially inward from the first circumference;
- a groove extending in a circumference around the holding ring end face;
- and
- at least one seal ring for contacting a surface of the ball, the at least one seal ring having at least one truncated cone region arranged thereat, and the at least one seal ring positioned at least partially within the groove.
An apparatus for sealing a ball joint of a kingpin, the apparatus comprising:
- a socket formed by a wall forming a first circumference around a central axis of a recess for receiving a ball of the ball joint along the central axis;
- at least one holding ring extending from the first circumference toward the central axis of the recess, a holding ring end face at a second circumference radially inward from the first circumference, and the holding ring end face oriented facing the central axis of the recess;
- a groove extending in a circumference around the holding ring end face;
- and
- a seal ring having at least one truncated cone region arranged thereat, the seal ring for contacting a surface of the ball, and the seal ring positioned at least partially within the groove.
A wheel suspension for a large construction machine having at least one apparatus for sealing a ball joint of a kingpin, the apparatus comprising:
- a socket formed by a wall forming a first circumference around a recess for receiving the ball joint, the wall extending in the direction of a center axis of the recess;
- at least one holding ring connected to an end face of the wall of the socket at the first circumference, the holding ring extending from the first circumference toward the center axis of the recess, and a holding ring end face at a second circumference radially inward from the first circumference;
- a groove extending in a circumference around the holding ring end face;
- and at least one seal ring for contacting a surface of the ball, the at least one seal ring having at least one truncated cone region arranged thereat, and the at least one seal positioned at least partially within the groove.
