BALL SCREW DRIVE FOR AN ACTUATOR GROUP - A simplified explanation of the abstract

This abstract first appeared for US patent application 18593556 titled 'BALL SCREW DRIVE FOR AN ACTUATOR GROUP

Simplified Explanation

The patent application describes a ball screw drive for a vehicle brake actuator assembly, consisting of a recirculating ball screw spindle and a spindle nut that moves axially along the spindle when the spindle rotates.

The ball screw drive has a recirculating ball screw spindle with at least one thread groove, and a spindle nut with a corresponding thread groove.
Balls are guided in the thread grooves to facilitate axial movement of the spindle nut when the spindle rotates.
The spindle nut is made from rolling bearing steel or C steel.

Key Features and Innovation

Rotatably mounted recirculating ball screw spindle
Spindle nut with open side mounted on the spindle
Thread grooves on both the spindle and spindle nut for guiding balls
Axial movement of the spindle nut along the rotational axis of the spindle
Spindle nut made from rolling bearing steel or C steel

Potential Applications

This technology can be used in various vehicle brake actuator assemblies to provide precise and efficient movement control.

Problems Solved

Questions about Ball Screw Drive Technology

What are the key components of a ball screw drive system?

A ball screw drive system typically consists of a recirculating ball screw spindle, a spindle nut, and balls that move within the thread grooves to facilitate axial movement.

How does the material of the spindle nut affect the performance of the ball screw drive?

The material of the spindle nut, whether rolling bearing steel or C steel, can impact the durability, precision, and efficiency of the ball screw drive system.

Original Abstract Submitted

A ball screw drive for an actuator assembly of a vehicle brake is disclosed, having a rotatably mounted recirculating ball screw spindle, on which a spindle nut open on one side is mounted. At least one thread groove is formed on the circumferential surface of the recirculating ball screw spindle, and a corresponding thread groove is formed on the inner surface of the spindle nut. A multiplicity of balls is guided in the thread grooves in such a way that rotation of the recirculating ball screw spindle brings about axial movement of the spindle nut along a rotational axis of the recirculating ball screw spindle. The spindle nut is manufactured from rolling bearing steel or from C steel.
