Abstract
A middle and rear axle balancing suspension sealed ring includes an outer oil seal and an inner oil seal, wherein the outer oil seal includes an outer support framework and an outer sealing body; the outer support framework cross section is in shape, the outer sealing body coats and fixes the outer support framework, an prolonging part is arranged on the outer sealing body at the outside of the upper end part of the outer support framework, a groove is provided at the inner side of the prolonging part, and a spring is provided in the groove; a main lip is arranged on the prolonging part at the back side of the groove; the inner oil seal includes an inner support framework and an inner sealing body; the inner sealing body coats and fixes the inner support framework, and the inner support framework cross section is in the shape; the seal lip of the inner sealing body is in interference fit with the outer oil seal; the upper surface of the inner oil seal leans against at the upper surface of the bending inner side space at the outside oil seal outer support framework. The seal lip of the outer oil seal of the utility model can ensure shaft rotary sealing, the inner oil is packaged on the shaft, and can move along with the shaft; and can prevent the leaking of lubricant oil and prevent the movement is new type of foreign oil seal lip seal ensures rotating shaft seals, oil encapsulated within the shaft, can be maintained with the external muddy from entering in the balancing suspension.
Description
Technical field
The utility model relates to a kind of seal arrangement, especially relate to a kind of in, back vehicle bridge equalizing type of suspension seal ring.
Background technique
At automobile running and when turning, in keeping, the back doube bridge travels synchronously, needs the equalizing type of suspension can be at any time according to road conditions adjustment doube bridge travelling state.For keeping stable, the effectively work of equalizing type of suspension internal mechanism, need in suspension, to increase lubricant oil.The equalizing type of suspension axle promptly will rotate again and move axially, and need prevent that so promptly the internal lubrication oil leakage from going out, and need prevent that again outside muddy water from entering.Present common oil sealing or anti-muddy water oil sealing (shown in accompanying drawing 1) seal in the time of can only guaranteeing rotary seal, sealing in the time of can not guaranteeing to move axially; If adopt and move axially Sealing, can not guarantee that again outside muddy water enters.
The model utility content
The technical problems to be solved in the utility model provide a kind of in, back vehicle bridge equalizing type of suspension seal ring.The sealing circle can keep moving axially with axle, can prevent that lubricant oil from spilling and outside muddy water enters equalizing type of suspension simultaneously.
For solving the problems of the technologies described above, the utility model adopts following technological scheme, and it comprises outer oil seal and inner oil seal;
Described outer oil seal comprises outer support frame and external sealed body; Described outer support frame cross section is
Shape, the described external sealed body outer support frame that is coated and fixed, the external sealed body in the outside, upper end portion of this outer support frame is provided with extending portion, and this extending portion inboard is provided with groove, is provided with spring in this groove; On the extending portion of the phase dorsal part of groove, be provided with main lip;
Support frame and interior seal in described inner oil seal comprises; The seal interior support frame that is coated and fixed in described, described in the support frame cross section be
Shape; The sealing lip of seal is crossed to win with outer oil seal and is cooperated in described; Described inner oil seal upper surface leans on the upper surface of support frame bending inner space outside outer oil seal.
Further, the external sealed body in the outside, the bending place of described outer support frame is provided with bump.
Further, the sulfuration of described outer support frame and external sealed body is structure as a whole.
Further, described interior support frame and the sulfuration of interior seal are structure as a whole.
Further, described inside and outside seal adopts the rubber material.
Further, described inside and outside support frame adopts the Common Straight Carbon Steel material.
Sealing configuration of the present utility model, the sealing lip of its outer oil seal can guarantee a rotary seal; Inner oil seal is contained on the axle, can keep moving axially with axle; Its inner oil seal and outer oil seal can prevent that lubricant oil from spilling and outside muddy water enters equalizing type of suspension.
