AI Technical Summary

Benefits of technology

The compensation mechanism effectively maintains consistent gear mesh load, minimizing friction variation and enhancing NVH, ride, and handling performance by compensating for wear and manufacturing variations over time.

Problems solved by technology

The worm / worm gear reduction assembly may wear over time and may impact the overall system feel and NVH performance.
The wear over time reduces friction between the worm / worm gear reduction assembly and may cause poor NVH performance.

Abstract

A bearing adjustment assembly includes a worm engaged with a worm gear. The assembly also includes a worm bearing located proximate an end of the worm. The assembly further includes a compensation mechanism engaging the worm bearing, the compensation mechanism being adjustable to bias the worm bearing to maintain or adjust a gear mesh load between the worm gear and the worm.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This patent application is a divisional application of U.S. patent application Ser. No. 16 / 262,424, filed Jan. 30, 2019, which claims the benefit of priority to U.S. Provisional Patent Application Ser. No. 62 / 624,323, filed Jan. 31, 2018, both of which are incorporated herein by reference in their entireties.BACKGROUND OF THE INVENTION[0002]Vehicles may employ a power steering assist mechanism. The power steering assist mechanism provides torque assist to a steering shaft of the vehicle through a worm / worm gear reduction assembly. The worm / worm gear reduction assembly may wear over time and may impact the overall system feel and NVH performance. The wear over time reduces friction between the worm / worm gear reduction assembly and may cause poor NVH performance.SUMMARY OF THE INVENTION[0003]According to one aspect of the disclosure, a power steering assembly includes a housing. The assembly also includes a worm gear disposed within in the h...
