Hub built-in type constant velocity apparatus with pre-load ring
A recently granted patent (Publication Number: US11850884B2) discloses a hub built-in type constant velocity apparatus that includes a hub housing with a constant velocity joint, an internal race, and a pre-load ring. The unique design features an end portion of the hub housing rolled upwards towards the pre-load ring to apply pressure to both the pre-load ring and the internal race. Additionally, a washer is positioned between the internal race and the pre-load ring to enhance functionality. The patent also details the inclusion of a boot coupled to the pre-load ring, with specific sealing portions and protrusions to prevent rotation and ensure proper functioning of the apparatus.
Furthermore, the patent describes a low friction structure on the pre-load ring to reduce frictional forces with the internal race, enhancing the overall performance of the hub built-in type constant velocity apparatus. The design also incorporates specific seating portions on the hub housing for accommodating the internal race and the pre-load ring, with corresponding steps to ensure proper alignment and functionality. These innovative features aim to improve the durability, efficiency, and reliability of constant velocity apparatus in various applications.
