Abstract
An axle assembly includes a connection assembly having a stationary portion and a rotary portion. The stationary portion is configured to couple to an inlet airflow assembly configured to be non-movably coupled to a beam housing, the rotary portion is configured to couple to an outlet airflow assembly configured to be non-movably coupled to a steering knuckle, the stationary portion forms a cavity configured to facilitate flow of pressurized air from the inlet airflow assembly to the rotary portion, and the rotary portion forms an airflow path configured to facilitate flow of the pressurized air from the cavity to the outlet airflow assembly.
Claims20
An axle assembly, comprising a connection assembly comprising a stationary portion and a rotary portion, the stationary portion is configured to couple to an inlet airflow assembly configured to be non-movably coupled to a beam housing, the rotary portion is configured to couple to an outlet airflow assembly configured to be non-movably coupled to a steering knuckle, the stationary portion forms a cavity configured to facilitate flow of pressurized air from the inlet airflow assembly to the rotary portion, and the rotary portion forms an airflow path configured to facilitate flow of the pressurized air from the cavity to the outlet airflow assembly.
An axle assembly, comprising:
- an inlet airflow assembly configured to receive pressurized air from a pressurized air source, wherein the inlet airflow assembly is configured to be non-movably coupled to a beam housing of the axle assembly;
- an outlet airflow assembly configured to provide the pressurized air to a tire, wherein the outlet airflow assembly is configured to be non-movably coupled to a steering knuckle of the axle assembly;
- and
- a connection assembly comprising a stationary portion coupled to the inlet airflow assembly and a rotary portion coupled to the outlet airflow assembly, wherein the stationary portion forms a cavity configured to facilitate flow of the pressurized air from the inlet airflow assembly to the rotary portion, and the rotary portion forms an airflow path configured to facilitate flow of the pressurized air from the cavity to the outlet airflow assembly.
An axle assembly, comprising:
- a beam housing;
- a steering knuckle configured to pivot about a steering axis relative to the beam housing;
- a steering kingpin configured to pivotally couple the steering knuckle to the beam housing;
- an inlet airflow assembly non-movably coupled to the beam housing, wherein the inlet airflow assembly is configured to receive pressurized air from a pressurized air source;
- an outlet airflow assembly non-movably coupled to the steering knuckle, wherein the outlet airflow assembly is configured to provide the pressurized air to a tire;
- and
- a connection assembly comprising a stationary portion coupled to the inlet airflow assembly and a rotary portion coupled to the outlet airflow assembly, wherein the stationary portion forms a cavity configured to facilitate flow of the pressurized air from the inlet airflow assembly to the rotary portion, and the rotary portion forms an airflow path configured to facilitate flow of the pressurized air from the cavity to the outlet airflow assembly.
