Abstract
The utility model provides a be used for automatic gearbox bolt complex seal gasket, its technical essential is: including annular skeleton and sealing rubber, in sealing rubber located the skeleton, sealing rubber's cross -section was the T font, and its planar both ends that constitute the T font are in the same direction as connecing by outer to interior gradually to the annular sealing edge of both sides slope, and middle part of its constitution T font is even spacing distribution at the gasket of sealing rubber internal surface, the gasket is interference fit with the bolt. The utility model discloses the leakproofness is good, can satisfy the cleanliness requirement, does not influence bolt intensity, reduces purchasing cost.
Description
Technical field:
The utility model relates to a kind of gasket seal, particularly a kind of gasket seal coordinated for automatic transmission bolt.
Background technique:
Often automatic transmission fluid is contained in automatic transmission, for ensureing the sealing of bolt cooperation position, often take to avoid oil to leak from bolt cooperation position at bolt cooperation position gluing or in the mode that bolt and flange fitting surface place increase O shape ring, but because automatic transmission requires higher to turbidity test, gluing can affect complete machine turbidity test, cause TRANS FAILSAFE PROG, and adopt bolt and flange fitting surface to increase the mode of O shape ring, circumference mating groove need be processed at bolt root, waste time and energy, and can bolt strength be had a strong impact on, O shape ring purchase cost is too high in addition.
Summary of the invention:
The utility model is overcome the deficiency existed in above-mentioned technology, and provide a kind of gasket seal coordinated for automatic transmission bolt, its good airproof performance, can meet turbidity test requirement, not affect bolt strength, saves cost.
The gasket seal coordinated for automatic transmission bolt of the present utility model, technological scheme adopted for achieving the above object is: the skeleton and the caulking gum that comprise annular, described caulking gum is located in skeleton, the cross section of caulking gum is in T shape, its two ends forming T-shaped plane are along the seal lip being connected to the annular tilted to both sides gradually from outside to inside, and it forms T-shaped middle part is the diaphragm seal being equidistantly distributed in caulking gum internal surface.
As further improvement of the utility model, described skeleton and caulking gum sulfuration link into an integrated entity, and it is connected firmly, closely.
As further improvement of the utility model, described skeleton is metal frame, and it is not yielding, is convenient to gasket seal and coordinates with bolt, and wear resistance is strong, can play good protective action to caulking gum.
As further improvement of the utility model, the thickness of described diaphragm seal is less than the thickness of whole skeleton and is greater than the thickness of 1/2 skeleton, can ensure the sealing of diaphragm seal, can save material again in this thickness range.
As further improvement of the utility model, the thickness of the outer surface of described caulking gum is identical with the thickness of skeleton, make both surface of contact completely crossing, caulking gum can be prevented to be out of shape by skeleton, can prevent the outer surface of caulking gum from wearing and tearing by skeleton again.
The beneficial effects of the utility model are: seal lip of the present utility model can fit tightly flanged surface to stop that the oil in speed changer flows out when bolt tightening, the position of whole gasket seal is retrained again by the interference fit of diaphragm seal and bolt, make gasket seal can complete sealing in effective coverage, thus ensure the sealing of bolt and flange fitting surface, ensure bolt strength, turbidity test requirement can be met, save cost.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is plan view of the present utility model;
Fig. 3 is sectional view of the present utility model.
Embodiment:
With reference to each accompanying drawing, this is used for the gasket seal that automatic transmission bolt coordinates, comprise skeleton 2 and the caulking gum 3 of annular, described skeleton 2 is metal frame, described caulking gum 3 is located in skeleton 2, skeleton 2 and caulking gum 3 sulfuration link into an integrated entity, the cross section of caulking gum 3 is in T shape, its two ends forming T-shaped plane are along the seal lip 4 being connected to the annular tilted to both sides gradually from outside to inside, it forms T-shaped middle part is the diaphragm seal 5 being equidistantly distributed in caulking gum 3 internal surface, and described diaphragm seal 5 is interference fit with bolt.The thickness of described diaphragm seal 5 is less than the thickness of whole metal frame 2 and is greater than the thickness of 1/2 metal frame 2.The thickness of the outer surface of described caulking gum 3 is identical with the thickness of skeleton 2.
During use, gasket seal is enclosed within bolt root, is retrained the position of whole gasket seal by diaphragm seal 5 and the interference fit of bolt, seal lip 4 can fit tightly flanged surface to stop that the oil in speed changer flows out when bolt tightening, thus realizes sealing.
