Abstract
The utility model discloses an inner sleeve assembly of an automotive steering lining. The inner sleeve assembly of the automotive steering lining comprises an annular steel sleeve with a shaft hole formed in the middle, wherein a plurality of protrusion are arranged at each of the two ends of the annular steel sleeve in a surrounding mode, the cross section of each protrusion is an isosceles trapezoid, a plurality of annular protrusions are arranged in the middle of the annular steel sleeve, a plastic casing pipe is arranged on the outer side of the annular steel sleeve in an injection molding mode, the protrusions and the annular protrusions of the annular steel sleeve are all in interference fit with the plastic casing pipe, and a plurality of annular supporting ribs are transversely arranged in the plastic casing pipe. According to the inner sleeve assembly of the automotive steering lining, due to the additional arrangement of the reinforcing ribs in the plastic casing pipe, the hardness of the plastic casing pipe is improved; meanwhile, due to the arrangement of the protrusions and the annular protrusions on the annular steel sleeve, friction between the plastic casing pipe and the annular steel sleeve is increased, and the qualified rate of products is increased.
Description
Technical field
The utility model relates generally to technical field, relates in particular to a kind of internal sleeve assembly of motor turning lining.
Background technology
What the motor turning lining that used in the past adopted is single interior nested structure, former motor turning lining comprises the tubular inner metal sleeve, adopt vulcanization adhesion one circle rubber ring in the outside of inner metal sleeve, when assembling, rubber ring and steering box metal steel pipe interference fit by the inner metal sleeve outer setting, come closure dish and steering box, make wheel steering sensitive, bush torsional rigidity must be large, usually by improving rubber ring hardness, meet, effect is undesirable, and the hardness of rubber ring is when too high, its production difficulty also strengthens, and the product of producing is difficult to reach client's requirement, qualification rate is lower, the waste raw MAT'L.
The utility model content
The utility model purpose is exactly in order to make up the defect of prior art, and a kind of internal sleeve assembly of motor turning lining is provided.
The utility model is achieved through the following technical solutions:
A kind of internal sleeve assembly of motor turning lining, it is characterized in that: the annular steel bushing that has axis hole in the middle of including, the two ends of annular steel bushing all are equipped with the projection that several cross-sectional planes are isosceles trapezoid, the middle part of annular steel bushing is provided with several annular protrusions, the outside of annular steel bushing is injected with plastic casing, the projection, annular protrusion of annular steel bushing all with the plastic casing interference fit, laterally be provided with some annular brace muscle in described plastic casing.
The utility model has the advantages that:
The utility model utilizes on the one hand increases the hardness that reinforced rib carrys out the reinforced plastics sleeve pipe in plastic casing, is provided with on the other hand projection, annular protrusion on annular steel bushing, increases the friction force between plastic casing and annular steel bushing, has improved the qualification rate of product.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is birds-eye view of the present utility model.
The specific embodiment
As shown in Figure 1, 2, a kind of internal sleeve assembly of motor turning lining, have the annular steel bushing 1 of axis hole in the middle of including, the two ends of annular steel bushing 1 all are equipped with the projection 2 that several cross-sectional planes are isosceles trapezoid, the middle part of annular steel bushing 1 is provided with several annular protrusions 3, the annular steel bushing 1 the outside be injected with plastic casing 4, the projection 2 of annular steel bushing 1, annular protrusion 3 all with plastic casing 4 interference fit, laterally be provided with some annular brace muscle 5 in described plastic casing 4.
