Abstract
A system and method of determining wear of a wheel seal assembly. A warning indicative of wear of the wheel seal assembly may be generated when a wheel speed exceeds a threshold wheel speed for first amount of time, when a tire pressure exceeds a threshold tire pressure for a second amount of time, and/or when a wheel end temperature exceeds a threshold wheel end temperature for a third amount of time.
Claims20
A method of determining wear of a wheel seal assembly, comprising:
- measuring an amount of time during which a wheel speed exceeds a threshold wheel speed;
- and
- generating a warning indicative of wear of the wheel seal assembly when the wheel speed exceeds the threshold wheel speed for a first amount of time.
A method of determining wear of a wheel seal assembly, comprising:
- measuring an amount of time during which a tire pressure exceeds a threshold tire pressure;
- and
- generating a warning indicative of wear of the wheel seal assembly when the tire pressure exceeds the threshold tire pressure for a second amount of time.
A system for determining wear of a wheel seal assembly, comprising:
- a hub that is rotatably disposed on a spindle;
- and
- a wheel speed sensor that provides data indicative of rotation of the hub to a control module;
- wherein the wheel seal assembly is disposed proximate the spindle and the hub and includes a seal passage that routes pressurized gas to a tire that is supported by the hub;
- and
- wherein the control module generates a warning indicative of wear of the wheel seal assembly when the wheel speed exceeds a threshold wheel speed for a first amount of time.
