Abstract
The utility model provides a high pressure dynamic steering tube of five-layer tube structure, comprising a rubber layer, a reinforcing layer, a rubber layer, a reinforcing layer and a rubber from inner to outer; wherein the reinforcing layers are two textile reinforcing layers. The high pressure dynamic steering tube adopts two textile reinforcing layers to confirm high pressure resistance and flexibility, and the textile reinforcing layers have high volume expansion property and can effectively eliminate operation noise of the power steering system. The high pressure dynamic steering tube has the advantages of having high pressure resistance, high flexibility and simple installment, and eliminating operation noise.
Description
Technical field
The utility model relates to a kind of pipe, particularly is used for a kind of high voltage power steering tube of automobile hydraulic electric power steering system.
Background technique
At present.The high-voltage tube working pressure that is used for the automobile hydraulic electric power steering system is generally 10Mpa.For satisfying the withstand voltage properties of high voltage power steering tube, the domestic high-voltage tube that is used for the automobile hydraulic electric power steering system generally adopts the braided steel wire structure.High voltage power steering tube of the prior art as shown in Figure 1, be the enhancement layer 2 and the rubber layer 1 of rubber layer 1, braided steel wire from inside to outside successively, though the high voltage power steering tube of this structure can satisfy the resistance to pressure requirement of high voltage power steering tube, but the enhancement layer of braided steel wire 2 has influenced the pliability of whole high voltage power steering tube, is unfavorable for the installation of high voltage power steering tube; In addition, because the existence of the enhancement layer 2 of braided steel wire, the high voltage power steering tube can produce noise when servo steering system is worked, and influences the travelling comfort of passenger car.
Summary of the invention
The utility model embodiment's purpose is the defective at above-mentioned prior art, and a kind of high voltage power steering tube is provided, and not only has barotolerance, and can eliminate the noise that produces when servo steering system is worked, and pliability is beneficial to installation well.
The technological scheme taked of the utility model embodiment is to achieve these goals: a kind of high voltage power steering tube, be five layers of tubular construction, comprise rubber layer, enhancement layer, rubber layer, enhancement layer and rubber layer from the inside to the outside in turn, wherein said enhancement layer is a braided fiber reinforcing layer.
In order to increase the expansivity of high voltage power steering tube under working pressure, the preferred PA66 fiber of described braided fiber reinforcing layer is made.
The utility model embodiment's beneficial effect is: compared to existing technology, embodiment described in the utility model has adopted five-layer structure, particularly adopted the structure of double-deck braided fiber reinforcing layer, barotolerance of the present utility model and pliability have been guaranteed, and because the high volumetric expansion performance that braided fiber reinforcing layer has, can eliminate the noise that servo steering system when work produces effectively, so have the resistance to pressure height, pliability is good, easy for installation and use noiseless advantage.
Description of drawings
Fig. 1 is the structural representation of high voltage power steering tube of the prior art;
Fig. 2 is the structural drawing of the described high voltage power steering tube of the utility model embodiment.
Among the figure: 1 rubber layer, the enhancement layer of 2 braided steel wires, 3 enhancement layers.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to qualification of the present utility model.
As shown in Figure 2, the described a kind of high voltage power steering tube of the utility model embodiment is five layers of tubular construction.Comprise the rubber layer 1 of first layer, the enhancement layer 3 of the second layer, the 3rd layer rubber layer 1, the 4th layer enhancement layer 3 and the rubber layer 1 of layer 5 from the inside to the outside in turn.Wherein, the enhancement layer 3 of the second layer and the 4th layer is the enhancement layer of fibrage.In order to increase the expansivity of high voltage power steering tube under working pressure, the enhancement layer 3 of described fibrage preferentially selects for use the big PA66 of elongation at break (nylon 66) fiber to make, and can make described high voltage power steering tube expansivity when (10Mpa) under working pressure reach 30% by the enhancement layer of PA66 fibrage layer after testing.
Embodiment described in the utility model has adopted the structural design of double-deck braided fiber reinforcing layer, on the one hand pliability of the present utility model is improved, and the resistance when having reduced to install is easy for installation; On the other hand, adopt this bilayer enhancement layer structure, make the utility model when in being subjected to, pressing certain expansion be arranged, can eliminate the noise of servo steering system.In sum, the utlity model has the resistance to pressure height, pliability is good, easy for installation and use noiseless advantage.
Above-described embodiment, the utility model embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection domain of the present utility model.
Claims (2)
