Description
Technical field
The invention belongs to Sealing, especially relate to a kind of oil sealing of automotive hub.
Background technique
Existing automobile, particularly truck, hub oil seal generally adopt the dual-oil seal sealing, promptly inside and outside two oil sealings are installed and are respectively applied for oil sealing, envelope dirt at the wheel hub seam, this spline structure is often bad because of two oil sealing coaxalitys, and play makes automobile wheel hub generation leakage of oil under steam easily.
Summary of the invention
The purpose of this invention is to provide a kind of automotive hub combination oil seal, design two seals lip on an oil tight skeleton make oil sealing possess oil sealing, envelope dirt function simultaneously, and the coaxality of two seal lips is good, seals tighter.
The object of the present invention is achieved like this: a kind of automotive hub combination oil seal, it is characterized in that this automotive hub combination oil seal is mainly by oil tight skeleton, seal ring and spring ring are formed, wherein, oil tight skeleton is mainly by main framing, left side support frame, right support frame three parts are formed, main framing is ganoid sheet metal stamping part, this main framing be left part take the shape of the letter U be bent to form fuse in, outer dicyclo body and outer ring body long (wide) and inner ring body short (narrow), and the left part diameter of the outer ring body of this main framing is the interior shape of receiving for a short time, the right-hand member section of the inner ring body of this main framing is again at right angles curved down upright ring body, interference press-fits or the at right angles crooked annular left support frame and make the upright anchor ring in a left side of this left side support frame and the U-shaped curved end of main framing be in same vertical plane of being welded on the lower surface of the left part of the inner ring body of main framing, and interference press-fits or the at right angles right support frame of crooked annular that is welded on the lower surface of the right part of the outer ring body of main framing, and the right-hand member of the outer ring body of upright anchor ring in the right side that makes this right side support frame and main framing is positioned at same vertical surface, and left support frame and right support frame are the sheet metal stamping part; In addition, on the upright ring body on the inner ring body right side of main framing, seal ring is installed, the sealing circle can be the vulcanized rubber seal ring, the transverse section of sealing circle is the mountain font, the peripheral part left and right sides at seal ring is provided with semicircle concave ring groove, corresponding respectively left spring circle and the right spring ring installed in this left and right sides concave ring groove, to increase parcel power, the middle part of interior week of this seal ring is to be to the arc surface of fovea superior and two ends, the left and right sides section in interior week to be the overhanging inclined-plane that makes progress, and left lip circle and the right lip circle of the intersection on this arc surface and inclined-plane, the left and right sides, and should a left side for protruding, the diameter of right lip circle is slightly less than the external diameter of oil sealing seat ring.
During use, the interference of this automotive hub combination oil seal is pressed in the wheel hub seam, its left and right lip circle tightly is wrapped on the oil sealing seat ring simultaneously, and automobile in motion like this, wheel hub rotates, and left and right lip circle rotates simultaneously, and coaxality is good, be difficult for left and right sides play, not easy oil leakage, good sealing effect.
Automotive hub combination oil seal proposed by the invention is rational in infrastructure, makes simply, and coaxality is good, is difficult for left and right sides play, and good sealing effect greatly reduces the leak-down rate of wheel hub.
Now in conjunction with the accompanying drawings and embodiments automotive hub combination oil seal proposed by the invention is described further.
