Abstract
A vehicle wheel end assembly includes a hub bearing assembly with an inner member having a first side defining a throughbore and a second side defining an inner raceway, a shaft extending through the throughbore of the inner member and configured to receive a torque and to transfer the torque to the inner member such that the inner member rotates with the shaft; and a seal positioned within the throughbore between the shaft and the inner member.
Claims20
A vehicle wheel end assembly, comprising:
- a hub bearing assembly comprising an inner member having a first side defining a throughbore and a second side defining an inner raceway,
- a shaft extending through the throughbore of the inner member and configured to receive a torque and to transfer the torque to the inner member such that the inner member rotates with the shaft;
- and
- a seal positioned within the throughbore between the shaft and the inner member.
A method for sealing a vehicle wheel end assembly having a hub bearing assembly and a half shaft, comprising the steps of:
- mounting a seal on a circumferential surface of the half shaft;
- and
- installing the hub bearing assembly on the half shaft such that the seal creates a first watertight interface with the hub bearing assembly and a second watertight interface with the half shaft.
A vehicle wheel end assembly, comprising:
- a hub bearing assembly comprising:
- an inner member having a first side defining a throughbore and a second side defining an inner raceway,
- an outer member having a first side defining an outer raceway, and
- a roller element positioned within the inner raceway and the outer raceway such that the inner member is rotatable relative to the outer member;
- a half shaft including a body portion extending through the throughbore of the inner member and engaging the inner member to transfer torque, the body portion having an inboard side and an outboard side;
- an O-ring configured to form a first seal between the half shaft and the inner member at the inboard side of the body portion;
- and
- a grommet configured to form a second seal between the half shaft and the inner member at the outboard side of the body portion.
