Abstract
An automobile redirector slide bearing is provided with a bearing body, two ring-shaped grooves arranged on the internal side face of the bearing body, and a ring-shaped external groove arranged at the periphery of the bearing body, wherein both the ring-shaped grooves arranged on the internal side face of the bearing body consist of two identical spherical zone faces, with the major diameter ends of the two spherical zone faces connected together, and therefore a peach-shaped raceway is formed. The utility model has a simple structure, and when in use, because the rolling body is in contact with four points in the raceway formed by the slide bearing and a screw rod, both the axial and radial location of the sliding bearing and the multi-head screw rod body can be guaranteed to be accurate.
Description
Technical field
The utility model relates to the automobile steering device slipper bearing.
Background technology
Along with the widespread use of Eltec on automobile, ECS Electronic Control Power Steering has become automobile power steering system development direction.China Patent No. is that 200420110889.0 utility model patent specification sheets discloses a kind of automobile electric power-assisted steering axle assembly, and it has worm-wheel shaft and is arranged on worm-wheel shaft can axially movable sliding sleeve.Described sliding sleeve medial surface is provided with two annular inner groovies, is provided with groove outside the annular on the outer peripheral face of sliding sleeve.Worm-wheel shaft is provided with spiral groove, is provided with ball between sliding sleeve annular groove and worm-wheel shaft spiral groove.The annular groove of above-mentioned sliding sleeve is the spherical zone shape, because ball and sliding sleeve annular groove have the gap between axially, so can not guarantee that the location between sliding sleeve and the worm-wheel shaft is accurate.
The utility model content
The purpose of this utility model be to propose a kind of can with the screw rod that matches between the location accurate automobile steering device slipper bearing.
For achieving the above object, the utility model is taked following technical scheme:
This practicality newly has bearing body, the bearing body medial surface is provided with two annular inner groovies that are in two ends respectively, the outer peripheral face of bearing body is provided with the outer groove of annular, annular inner groovy on the described bearing body medial surface is formed by two identical spherical zone faces, the larger diameter end of two spherical zone faces is joined, thereby forms peach shape raceway.
The utlity model has following good effect:
1, the utility model bearing body has peach shape raceway, and when using, rolling body is at 4 and contacts in slipper bearing and raceway that the multiple-threaded screw body forms, guarantee between slipper bearing and the multiple-threaded screw body axial, radial location is accurate.
2, because the existence of the two raceways of bearing body, the phenomenon that can not be distorted when making transmission, and play auto-lock function when having transmission.
3, owing on the outer peripheral face of bearing body, be provided with groove outside the annular, be used to install the whipstock system sensor, reduced the parts in the electric booster steering device system, simplified mechanism.
4, the utility model plays slide block and bearing dual-use function.
Description of drawings
For the easier quilt of content of the present utility model is clearly understood, below the specific embodiment and in conjunction with the accompanying drawings of basis, the utility model is described in further detail, wherein
Fig. 1 is a configuration diagram of the present utility model;
Fig. 2 is a peach shape raceway diagrammatic sketch.
The specific embodiment
Fig. 1 and a kind of automobile steering device slipper bearing shown in Figure 2, has bearing body 1, bearing body 1 medial surface is provided with two annular inner groovies 2 that are in two ends respectively, the outer peripheral face of bearing body 1 is provided with the outer groove 3 of annular, annular inner groovy 3 on the described bearing body medial surface is formed by two identical spherical zone face 2-1, the bigger diameter end of two spherical zone face 2-1 joins, and causes two spherical zone face 2-1 intersections to generate broken line a, thereby forms peach shape raceway.B point among Fig. 2 is the contact point of rolling body and bearing body 1.
When using, slipper bearing is connected on the screw rod, the spiral of screw rod also is a peach shape raceway, be provided with rolling body between slipper bearing and the screw rod, rolling body is 4 contacts in raceway, four contact points have limited the diameter clearance and the endplay of rolling body, guarantee between slipper bearing and the multiple-threaded screw body axial, radial location is accurate.
