Abstract
The utility model discloses a bushing for a steering gear rack. The bushing comprises a bushing body, wherein a plurality of oil storage holes for storing solid lubricating grease are formed in the bushing body; the diameters of openings of the oil storage holes in the outer wall of the bushing body are smaller than the diameters of openings of the oil storage holes in the inner wall of the bushing body; bosses are respectively outwards arranged at two ends of the bushing body; and four bayonets are uniformly formed in the bottom of each boss. The bushing disclosed by the utility model is not likely to wear; the lubricating grease is not likely to leak out; and the bushing can also be tightly matched with the rack.
Description
Technical field
The utility model relates to a kind of automobile steering device, especially relates to a kind of steering gear rack lining.
Background technology
Tubular lining on the present automobile steering device, after long-time the use, because lubricant effect is bad, lining is easy to wearing and tearing, make the bigger gap of formation between lining and tooth bar, and plain bushing is difficult to closely cooperate with tooth bar, therefore after liner wear, the deflector meeting produces bigger noise, even might make the positive excessive velocities of returning of bearing circle, is unfavorable for normally travelling.
Therefore the lining for the groove that stores grease occurs having, but because the aperture is too big, caused grease to be easy to spill very much, caused waste.
The utility model content
The problem that the utility model spills easily for the lubricating grease on the rack bush that solves present deflector, a kind of steering gear rack lining is provided for this reason, comprise bush body, offer some oil storage holes for the store solids lubricating grease on the described bush body, preferably, oil storage hole is 30～50, described oil storage hole at the opening diameter of bush body outer wall less than the opening diameter at the bush body inwall; The two ends of described bush body also all outwards are provided with boss, and the bottom of described each boss also all has four bayonet sockets.
The utility model steering gear rack lining, the external diameter of described boss is greater than the external diameter of bush body.
The beneficial effects of the utility model are:
The utility model since oil storage hole in the aperture of bush body outer wall less than the aperture of inwall, and be the solid lubrication grease, so can not overflow or spill, not easy to wear; And the setting of four bayonet sockets in boss bottom makes tooth bar and the cooperating of lining can be tightr.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is scheme drawing of the present utility model.
The specific embodiment
Disclosed all features in this specification sheets, or the step in disclosed all methods or the process except mutually exclusive feature and/or step, all can make up by any way.
Disclosed arbitrary feature in this specification sheets (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.
Steering gear rack lining as shown in Figure 1, comprise bush body 1, offer some oil storage holes 2 for the store solids lubricating grease on the described bush body 1, preferably, oil storage hole is 30～50, described oil storage hole 2 at the opening diameter of bush body 1 outer wall less than the opening diameter at bush body 1 inwall; The two ends of described bush body 1 also all outwards are provided with boss 3, and the external diameter of described boss 3 is greater than the external diameter of bush body 1, and the bottom of described each boss 3 also all has four bayonet sockets 4.
The utility model since oil storage hole in the aperture of bush body outer wall less than the aperture of inwall, and be the solid lubrication grease, therefore can not overflow, also be difficult for spilling, and the setting of four bayonet sockets makes tooth bar and the cooperating of lining can be tightr bottom the boss.
The utility model is not limited to the aforesaid specific embodiment.The utility model expands to any new feature or any new combination that discloses in this manual, and the arbitrary new method that discloses or step or any new combination of process.
