ECCENTRIC BEARING RACK ANTI-ROTATION ASSEMBLY - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240034391 titled 'ECCENTRIC BEARING RACK ANTI-ROTATION ASSEMBLY

Simplified Explanation

The abstract describes a steer-by-wire system for a vehicle that includes a ball screw, a ball nut, and a bearing assembly. The ball nut is threadedly coupled to the ball screw, and its rotation causes the translation of the ball screw. The bearing assembly consists of an inner race and an outer race with an outer surface that fits into an axial groove in the ball screw, preventing its rotation.

  • The patent application describes a steer-by-wire system for vehicles.
  • The system includes a ball screw and a ball nut that actuates the translation of the ball screw.
  • A bearing assembly is included to prevent the rotation of the ball screw.
  • The bearing assembly consists of an inner race and an outer race with an outer surface that fits into an axial groove in the ball screw.

Potential Applications:

  • Automotive industry: This technology can be applied in vehicles to enable steer-by-wire systems, eliminating the need for mechanical connections between the steering wheel and the wheels.
  • Autonomous vehicles: Steer-by-wire systems are crucial for autonomous vehicles, as they allow for precise control and maneuverability without human intervention.
  • Electric vehicles: Implementing steer-by-wire systems can enhance the efficiency and design flexibility of electric vehicles.

Problems Solved:

  • Eliminates mechanical connections: The steer-by-wire system eliminates the need for traditional mechanical connections between the steering wheel and the wheels, reducing complexity and potential failure points.
  • Improved control and maneuverability: By enabling precise control over steering, the system enhances maneuverability and responsiveness, especially in autonomous vehicles.
  • Design flexibility: The system allows for more freedom in vehicle design, as it eliminates the constraints imposed by traditional steering systems.

Benefits:

  • Enhanced safety: The steer-by-wire system can improve safety by providing more precise and reliable steering control, reducing the risk of accidents caused by mechanical failures.
  • Improved driving experience: The system offers smoother and more responsive steering, enhancing the overall driving experience for both manual and autonomous vehicles.
  • Design flexibility: By eliminating the need for mechanical connections, the system allows for more innovative and space-efficient vehicle designs.


Original Abstract Submitted

a steer-by-wire system for a vehicle includes a ball screw. the steer-by-wire system also includes a ball nut threadedly coupled to the ball screw, wherein rotation of the ball nut actuates translation of the ball screw. the steer-by-wire system further includes a bearing assembly. the bearing assembly includes an inner race. the bearing assembly also includes an outer race having an outer surface disposed within an axial groove defined within the ball screw to prevent rotation of the ball screw.
