Abstract
The utility model discloses a bushing for an automobile steering device. The bushing comprises a steel substrate (1), wherein a plastic layer (2) is arranged on the inner layer of the steel substrate (1), and an antirust paint layer (3) is coated on the outer layer. The bushing for the automobile steering device disclosed by the utility model is low in friction coefficient, good in wear-resisting property, and high in mechanical strength; and the inner layer is anticorrosive and the outer layer is antirust.
Description
Technical field
The utility model relates to the automobile steering device field, especially relates to a kind of automobile steering device lining.
Background technique
This type of lagging material of the supporting rack bar that existing automobile gear tooth bar steering box is used is generally engineering plastics, as polyoxymethylene or powder metallurgy, exist friction factor greatly, not wear-resisting, compressive strength is not high or the high in cost of production problem.
The model utility content
The utility model for the lining friction factor that solves present automobile gear tooth bar steering box and use greatly, not wear-resisting, compressive strength is not high or the high in cost of production problem, a kind of automobile steering device lining is provided for this reason, comprise steel base 1, the internal layer of described steel base 1 is provided with plastic layer 2, and skin scribbles rust preventive coating 3.
The utility model automobile steering device lining comprises teflon in described plastic layer 2.
The utility model automobile steering device lining is filled with copper powder and graphite in described teflon.
The beneficial effects of the utility model are:
The utility model is owing to having added the plastic layer of teflon at the steel base internal layer, both improved its frictional behaviour, mechanical strength and corrosion protection have been improved again, especially be filled with copper powder and graphite in the teflon inland sea, need not to add again oiling agent, just can reach the purpose that friction factor is little, wear-resisting property is good; And the rust proof paint that the steel base skin is coated with has been avoided after long-term the use, the problem of steel base outer surface corrosion.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is schematic diagram of the present utility model.
Embodiment
Disclosed all features in this specification, or the step in disclosed all methods or process except mutually exclusive feature and/or step, all can make up by any way.
Disclosed arbitrary feature in this specification (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 similar characteristics.
Automobile steering device lining as shown in Figure 1, comprise steel base 1, the internal layer of described steel base 1 is provided with plastic layer 2, comprise teflon in described plastic layer 2, be filled with copper powder and graphite in described teflon, both improved its frictional behaviour, mechanical strength and corrosion protection have been improved again, especially be filled with copper powder and graphite in the teflon inland sea, need not to add again oiling agent, just can reach the purpose that friction factor is little, wear-resisting property is good.Skin scribbles rust preventive coating 3, has avoided after long-term the use problem of steel base outer surface corrosion.
The utility model is not limited to aforesaid 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.
