PCT No. PCT/EP89/01531 Sec. 371 Date Apr. 26, 1991 Sec. 102(e) Date Apr. 26, 1991 PCT Filed Dec. 13, 1989 PCT Pub. No. WO90/06879 PCT Pub. Date Jun. 28, 1990.A steering gear, especially for motor vehicles, has a steering worm sector shaft (10) including a toothed quadrant and a steering nut (4) displaceable axially by a steering shaft and engaging with the toothed quadrant with a steering rack section (7). To eliminate the toothing play occurring between the toothed quadrant and the steering rack section (7), a spring pressure element (14) is provided that is located outside of the surface plane that includes the axis of the steering shaft and is perpendicular to the toothing surface plane of the steering rack section (7), and that exerts a twisting force on the steering nut (4) in the straight-ahead-travel position of the steering gear. The spring pressure element (14) includes two spring washers (15, 16) located concentrically with each other on the steering worm sector shaft (10). The two spring washers (15, 16) are connected with each other by a connecting arm (17). The outer spring washer (15) bears an extension (18) directed radially outward that has the shape of the central tooth of the toothed quadrant and is supported by the steering rack section (7) in the straight-ahead-travel position of the steering gear. The side of the inner spring washer (16) facing the steering rack section (7) is supported by the steering worm sector shaft (10). |
