CONSTANT VELOCITY JOINT FOR VEHICLE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18238742 titled 'CONSTANT VELOCITY JOINT FOR VEHICLE

Simplified Explanation

The abstract describes a constant velocity joint for a vehicle, which is a component that transmits power from a shaft to the axle housing. The joint includes an axle housing fixed to a knuckle by a hub bearing, and a joint assembly with multiple joint balls.

  • The axle housing has an extension portion that extends from its end in a radial direction.
  • The extension portion applies a pressing force to the inner race of the hub bearing in an axial direction.
  • A boot surrounds the outer side of the extension portion and is coupled to it, creating a restraining force between the extension portion and the boot in the axial direction.

Potential applications of this technology:

  • Automotive industry: This constant velocity joint can be used in various vehicles, such as cars, trucks, and SUVs, to transmit power efficiently and smoothly.

Problems solved by this technology:

  • Power transmission: The constant velocity joint ensures a constant velocity of the rotating shaft, allowing for smooth power transmission to the axle housing.
  • Axle housing stability: The extension portion provides a pressing force to the hub bearing, enhancing the stability of the axle housing.

Benefits of this technology:

  • Improved performance: The constant velocity joint allows for efficient power transmission, resulting in better vehicle performance and handling.
  • Enhanced durability: The design of the joint assembly and the use of a boot help protect the joint balls and other internal components, increasing the durability and lifespan of the joint.


Original Abstract Submitted

A constant velocity joint for a vehicle. The constant velocity joint includes: an axle housing fixed to a knuckle by a hub bearing, and a joint assembly inserted into the axle housing to transmit power from a shaft to the axle housing through a plurality of joint balls. In particular, the axle housing includes an extension portion which is extended from an end portion of the axle housing in a radial direction of the axle housing, and the extension portion provides a pressing force to an inner race of the hub bearing in an axial direction of the axle housing. The constant velocity joint further includes a boot surrounding an outer side of the extension portion and coupled to the extension portion so as to form a restraining force between the extension portion and the boot in the axial direction.
