Abstract
The utility model discloses a double -deck dust cover of connecting rod, including ball round pin seal port, dustproof cover body and ball key seat seal port, dustproof cover body adopts the double -deck wavy body structure that covers, evenly is equipped with a plurality of pairs of skeletons in the port wall rubber at dustproof cover body upper end ball round pin seal port border on the same horizontal direction. The utility model discloses the dust cover is convenient for install by lip outside the upper end of ball round pin seal port is equipped with, and dustproof cover body adopts the bilayer to cover the body structure wave upon wave, has improved the dustproof effect of dust cover, the skeleton can strengthen the atress effect and the anti -impact of dust cover. The toughness and the intensity of dust cover are enough to maintain it and use the long period under the condition of frequent atress, have prolonged life.
Description
Technical field
The utility model belongs to manufactruing equipment of automobile technical field, relates to a kind of rubber seal, is specifically related to the double-deck dust cover of a kind of connecting rod.
Background technology
In the power unit of motor vehicle, between the connector of motion transmission, adopt dust cover to carry out dust seal more. Existing dust cover adopts natural rubber more, installs and uses inconvenience, and structural design is unreasonable, and dust-proof effect is poor. Particularly, under frequent stressed and rotation situation, toughness and requirement of strength to dust cover are higher; And dust cover of the prior art does not reach this requirement conventionally, service life is short.
Utility model content
For above-mentioned the deficiencies in the prior art, the utility model provides a kind of connecting rod double-deck dust cover.
The technical solution adopted in the utility model is:
The double-deck dust cover of a kind of connecting rod, comprise ball pin seal, dustproof cover body and ball pin seat seal, dustproof cover body adopts double-layer wave formula cover body structure, in the port wall rubber at ball pin seal edge, dustproof cover body upper end, in same level direction, is evenly provided with some secondary skeletons.
Further, the cross section of skeleton is L-type.
Further, be provided with outer lip in ball pin seal outer edge upper end, dust cover body wall upper end, outer lip be shaped as uncovered type.
Further, outer lip and dustproof cover body are same rubber global formation, and the mounting structure of skeleton is: skeleton is built in port wall rubber and bonds together with rubber, and skeleton is installed and synchronizeed with double-deck dust cover rubber-moulding.
The utility model beneficial effect is obvious: (1) is provided with outer lip in the upper end of ball pin seal, is convenient to install dust cover, and dustproof cover body adopts double-layer wave formula cover body structure, has improved the dust-proof effect of dust cover; (2) in the rubber of dustproof cover body upper end, skeleton is set, can strengthens stressed effect and the resistance to impact of dust cover. The toughness of dust cover and intensity, be enough to maintain it and use the long period frequent stressed in the situation that, extended service life.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Reference numeral: ball pin seal 1, dustproof cover body 2, ball pin seat seal 3, skeleton 4.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described further, but scope of the present utility model is not limited to following embodiment.
Embodiment 1
As shown in the figure, the double-deck dust cover of a kind of connecting rod, comprise ball pin seal 1, dustproof cover body 2 and ball pin seat seal 3, dustproof cover body 2 adopts double-layer wave formula cover body structure, is evenly provided with the skeleton 4 of six secondary L-type steels in the port wall rubber at dustproof cover body 2 ball pin seal 1 edges, upper end in same level direction.
Be provided with uncovered type outer lip in dust cover body wall 2 upper end ball pin seal 1 outer edge upper ends.
Outer lip and dustproof cover body 2 are same rubber global formation, and the mounting structure of skeleton 4 is: skeleton 4 is built in port wall rubber and bonds together with rubber, and skeleton 4 is installed and synchronizeed with double-deck dust cover rubber-moulding.
The ball pin seal 1 of dust cover is connected with ball pin, and in ball pin seal, 1 is provided with two dustproof profile of tooth circles, profile of tooth circle tooth depth 1mm. Ball pin seat seal 3 is clamped and is fixed on ball pin seat by clip.
