RU95110576A - Integrated steering mechanism - Google Patents

Abstract

FIELD: mechanical engineering; transport; steering gears. SUBSTANCE: steering mechanism has housing 1 accommodating piston 5 with toothed rack 9 engaging with gear sector 10. Piston 5 is connected with screw shaft 12 through ball-and-screw drive 13. Shaft 12 is connected with spool 15 of working liquid distributor through torsion bar 28. Distributor spool is manually driven from steering wheel. Screw shaft 12 has section 36 enclosing sleeve 14 of distributor on part of its length. Thrust roller bearing 37 is installed between end face section 36 of shaft 12 and housing 1. Bearing 37 is located in recess made in housing 1. Thrust roller bearing 38 is installed at opposite end of shaft 12. EFFECT: provision of compact design with reliable supports for shafts.

Claims (1)

The steering mechanism comprises a housing in which a piston with a gear rack is located, which is engaged with the gear sector. The piston is connected via a ball screw transmission to a screw shaft, which is connected with a torsion bar to the spool of the working fluid distributor, which has a manual drive from the steering wheel. The helical shaft 12 has a section covering the sleeve of the distributor on a part of its length. Between the end of the shaft section and the housing is mounted a thrust roller bearing located in a recess made in the housing. A roller thrust bearing is located at the opposite end of the shaft. Such a steering mechanism with an integrated hydraulic booster has a compact design with reliable shaft supports.
