HALF SHAFT AND HUB BEARING ASSEMBLY - A simplified explanation of the abstract
This abstract first appeared for US patent application 18124511 titled 'HALF SHAFT AND HUB BEARING ASSEMBLY
The abstract describes a patent application for a half shaft and hub bearing assembly, which includes a half shaft with a CV joint outer race and a stub axle, as well as a hub bearing with a body, bore, and hub flange.
- The CV joint outer race features an annular groove on the first axial face, while the half shaft has a first chamfered shoulder with a chamfer angle.
- The hub bearing body has a bore that receives the stub axle, with a second axial face opposing the CV joint outer race's first axial face and a gap in between.
- The hub bearing also includes a second chamfered shoulder that engages the first chamfered shoulder of the half shaft, along with a hub flange extending radially from the body.
- A seal ring is placed in the annular groove of the CV joint outer race, with the seal ring positioned against the second axial face of the hub bearing.
Potential Applications: - Automotive industry for vehicles requiring half shaft and hub bearing assemblies. - Manufacturing sector for machinery that utilizes similar components.
Problems Solved: - Improved stability and functionality of the half shaft and hub bearing assembly. - Enhanced sealing capabilities to prevent contamination and damage.
Benefits: - Increased durability and longevity of the assembly. - Reduced maintenance and repair costs for vehicles and machinery.
Commercial Applications: - Automotive manufacturers and suppliers. - Industrial machinery companies.
Questions about the technology: 1. How does the design of the seal ring contribute to the overall performance of the assembly? 2. What are the specific advantages of the chamfered shoulders in the half shaft and hub bearing components?
Original Abstract Submitted
A half shaft and hub bearing assembly includes a half shaft including a CV joint outer race and a stub axle extending from the CV joint outer race. The CV joint outer race includes a first axial face including an annular groove and the half shaft includes a first chamfered shoulder having a chamfer angle. A hub bearing includes a body having a bore therethrough that receives the stub axle. The body includes a second axial face opposing the first axial face of the CV joint outer race with a gap therebetween and a second chamfered shoulder engaging the first chamfered shoulder. The hub bearing includes a hub flange extending radially from the body. A seal ring is received in the annular groove in the first axial face of the CV joint outer race and the seal ring being disposed against the second axial face of the hub bearing.
