Abstract

1316293 Power steering DIAMLER-BENZ A G 6 Aug 1970 [8 Aug 1969] 38003/70 Heading B7H In a power assisted vehicle steering system having a steering nut 13 rotatable but not axially displacable in a piston 12 and engageable with an axially fixed worm 15, the axes of a rocker shaft 17, and a slide valve 21 and the centre transverse plane 26 of the nut 13 are located in a common transverse plane of the housing when the piston is at its mid stroke, the axes of the valve 21 and rocker shaft 17 being perpendicular. A cavity passing through the piston 12 accommodates the nut 13 which has a finger 35, Fig. 1, for operating the valve 21. A sleeve 40 is made integral with an end cover 42 in which the shaft portion 47 is mounted by a bearing arrangement 46. Seals 37, 39 seal the working spaces 22, 23 from each other. The worm 15 is supported in the piston 12 by way of ball circuit 14, nut 13 and an oblique contact bearing 47. A roller bearing 48 which allows radial movement of the nut 13 can travel over the inner end 49 of the sleeve 40. In a modification, Fig. 4 (not shown), the oblique contact ball bearing 47 of Fig. 2 is replaced by radial and thrust roller bearings (347a), (347b). In another modification, Fig. 3 (not shown), the inner end of the steering worm 15 is supported by a radial roller bearing (256) in the end of the housing and the steering nut is mounted to permit radial movement at both bearing points.
