Background technique
According to differences such as road shape, travelling speeds, vehicle active adjustment vehicle body height reaches a best body gesture, to meet the usage requirement of multiple road.The suspension type possessing ride height control system does not generally adopt Mai Fuxun form, because piston rod can drive oil inlet pipe to rotate together in vehicle travel process.Therefore, under ensureing that gross vehicle arranges the prerequisite adopting Mai Fuxun structural type, should accomplish that the oil pipe of Vehicular turn to fixing vehicle body relative position is unaffected, under also will ensureing high pressure operations, the oil gas of height self-adjustment shock absorber inside must not have leakage.
And the height self-adjustment shock absorber on existing vehicle, when Vehicular turn, shock absorber piston rod can rotate thereupon, and to be connected with vibration damper by oil pipe and the oil pump be fixed on vehicle body can be affected, oil pipe there will be the phenomenons such as bending, and oil gas can be caused time serious to reveal.
Model utility content
The utility model provides a kind of vibration damper steering knuckle, and object is that the oil pipe avoiding being connected with vibration damper can not be affected when piston rod rotation.
To achieve these goals, the technological scheme that the utility model is taked is: vibration damper steering knuckle, comprising:
Fittings body, it is sheathed on the end of the piston rod of vibration damper, and inside is provided with oil duct; And
Frame, it is sheathed on fittings body for rotatable, and is provided with for being connected with oil pipe and the interface be communicated with the oil duct in fittings body.
Described fittings body comprises the path section being sheathed on large footpath section on piston rod and outer diameter and being less than large footpath section outer diameter, is provided with the axis hole allowing path section insert in described frame.
Be provided with seal ring before described frame and described path section, and seal ring is arranged at described interface both sides.
Described seal ring is sealed seal for this spy.
Bearing is provided with between described frame and described fittings body.
Described bearing is single-groove grooved groove bearing.
Vibration damper steering knuckle of the present utility model, by arranging the fittings body be connected with piston rod and the frame be sheathed on fittings body, frame also can be connected with one end of oil pipe, the oil pipe the other end connects oil pump, because frame is rotatable relative to fittings body, therefore when Vehicular turn makes piston rod drive fittings body to rotate, frame can keep motionless, also oil pipe and oil pump just can be avoided to be affected accordingly, oil pipe form can remain unchanged, and the oil gas transmitting high pressure conditions between vibration damper and oil pump is not easily revealed.
