Abstract
The invention belongs to the field of car fittings and in particular relates to an automobile steering power pipe which comprises a rubber soft pipe and two metal hard pipes connected in the rubber soft pipe, wherein the two metal hard pipes are both connected with an engine interface; pressure oil passes through spaces among the rubber soft pipe and the metal hard pipes at the same time; the rubber soft pipe comprises a seal pressure resisting layer, a temperature resisting layer and a braiding layer; wherein the seal pressure resisting layer serves as an innermost layer, the temperature resisting layer serves as a middle layer, and the braiding layer serves as an outermost layer; a plurality of raised lines are uniformly and axially arranged on the inner wall of the seal pressure resisting layer; the cross section of each raised line is ladder-shaped; and an inverted ladder-shaped groove is formed between every two of the raised lines. The automobile steering power pipe has the advantages that the turning circulation capability of oil in an oil path is enhanced by the rough raised lines, and the process of compressing, expanding and recompressing is formed for the oil path by a diameter expanding section, so that better steering operation can be realized; and therefore, the automobile steering power pipe has the advantages of good using effect and long service life.
Description
Technical field
The invention belongs to the auto parts machinery field, specifically is a kind of motor turning power pipe.
Background technique
The mechanical steering device of automobile can be realized turning to of automobile, but when the steering shaft load is big, only depends on driver's muscle power then to be difficult to turn to smoothly as steerable energy.In order to have alleviated the active force of pilot control steering wheel, people increase by a cover servosteering power assisting device on the basis of mechanical steering device.The hydraulic action that the servosteering power assisting device relies on hydraulic oil to produce drives steering shaft and rotates, thereby has alleviated the active force of pilot control steering wheel.High-pressure oil pipe in this servosteering power assisting device is the critical piece that transmits hydraulic power.The automotive power steering high-pressure oil pipe of prior art comprises the braiding rubber hose, connects metal hard tube and the joint of motor interface, described joint comprises the connecting end of metal hard tube and is enclosed within the connecting end of the rubber hose on the metal hard tube connecting end, and be enclosed within metal sleeve on the rubber hose connecting end, pipe rubber layer in the rubber hose of this structure automotive power steering high-pressure oil pipe comprises, crust rubber layer and the braiding of the fibre threads between interior pipe rubber layer and crust rubber layer enhancement layer.The rubber hose of the automotive power steering high-pressure oil pipe of this structure in actual use, because the pressure of the hydraulic oil in the rubber hose is bigger, the rubber hose bearing capacity of three-decker is little, is prone to booster, causes the servosteering power assisting device to lose power steering.
Summary of the invention
The problem to be solved in the present invention provides a kind of good weatherability, automobile power steering tube that bearing capacity is big, and its long service life is saved cost.
The invention provides following technological scheme:
Motor turning power pipe, two metal hard tubes that it comprises a rubber hose and is connected rubber hose inside, two metal hard tubes all are connected with the motor interface, pass through pressure oil simultaneously between described rubber hose and the metal hard tube, described rubber hose is provided with three layers, comprise sealing Withstand voltage layer, heat blocking layer and braid, the sealing Withstand voltage layer is the innermost layer, heat blocking layer is the mesosphere, outermost surface is braid, sealing Withstand voltage layer inwall axially evenly is provided with some raised lines, and the cross section of raised line is trapezoidal, forms between each raised line to fall trapezoidal groove.
Described raised line rough surface.
Also be provided with extension diameter section on described two metal hard tubes.
Advantage of the present invention is the upset circulation ability that strengthens oil in the oil circuit by coarse raised line, by the process of extension diameter section by oil circuit formation compression, expansion, recompression, can better turn to, thereby using effect is good long service life.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 be among Fig. 1 A-A to schematic cross-section.
Embodiment
As Fig. 1, shown in Figure 2, motor turning power pipe, two metal hard tubes that it comprises a rubber hose 1 and is connected rubber hose 1 inside, they are respectively metal hard tube 2 and metal hard tube 3, two metal hard tubes all are connected with the motor interface, pass through pressure oil simultaneously between described rubber hose and the metal hard tube, described rubber hose 1 is provided with three layers, comprise sealing Withstand voltage layer 1a, heat blocking layer 1b and braid 1c, sealing Withstand voltage layer 1a is the innermost layer, heat blocking layer 1b is the mesosphere, outermost surface is braid 1c, sealing Withstand voltage layer 1a inwall axially evenly is provided with some raised lines 4, and the cross section of raised line is trapezoidal, forms between each raised line to fall trapezoidal groove.
Described raised line rough surface.
Also be provided with extension diameter section on described two metal hard tubes.
