Abstract
The utility model discloses an uncovered type swing arm dust cover, including ball round pin seal port, dustproof cover body wall and ball key seat seal port, lip outside ball round pin seal port outside is equipped with along the upper end on the dustproof cover body wall evenly is equipped with a plurality of pairs of skeletons on the same horizontal direction in the port wall rubber. The utility model discloses beneficial effect is obvious: (1 )The dust cover is convenient for install by lip outside the upper end of ball round pin seal port is equipped with, and is simple and efficient during the use, (2 )The skeleton is set up in the rubber of dustproof cover body wall upper end, the atress effect and the anti -impact of dust cover can be strengthened. 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
This utility model belongs to manufactruing equipment of automobile technical field, relates to a kind of rubber seal, is specifically related to a kind of open type swing arm dust cover.
Background technology
In the power unit of motor vehicles, between the connector of motion transmission, many employing dust covers carry out dust seal. Existing dust cover many employings natural rubber, under frequent stress and rotation situation, toughness and requirement of strength to dust cover are higher; And dust cover of the prior art is typically not capable of this requirement, service life is short. Meanwhile, the dust cover having in manufacturing process can produce slit cracking, and rubber cracking place can produce some slits, although sometimes with perusal less than, but in long-term fierce motor process, due to quality dissatisfaction; Dust cover meeting cracking failure, dust-proof effect is poor, and motion transmission is produced harmful effect.
Utility model content
For above-mentioned the deficiencies in the prior art, this utility model provides a kind of open type swing arm dust cover.
The technical solution adopted in the utility model is:
A kind of open type swing arm dust cover, including ball pin seal, dust cover body wall and ball pin seat seal, is provided with outer lip in ball pin seal outer edge upper end, dust cover body wall upper end, is uniformly provided with some secondary skeletons in port wall rubber on same level direction.
Further, outer lip be shaped as open type.
Further, the cross section of skeleton is L-type.
Further, the maximum gauge place on dust cover body wall outer wall is provided with die parting line circle.
Further, this body wall thickness at the maximum gauge place on dust cover body wall outer wall is minimum.
Further, the cross section of die parting line circle is circular arc type, and die parting line circle and dust cover body wall junction seamlessly transit.
Further, die parting line circle and outer lip and dust cover body wall 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 Tong Bu with swing arm dust cover rubber-moulding.
Further, some dust-proof profile of tooth circles, profile of tooth circle tooth depth 0.6mm it are provided with in ball pin seal.
This utility model beneficial effect is obvious: (1) is provided with outer lip in the upper end of ball pin seal, it is simple to install dust cover, simple and efficient during use; (2) skeleton is set in the rubber of dust cover body wall upper end, stressed effect and the resistance to impact of dust cover can be strengthened.The toughness of dust cover and intensity, it is sufficient to maintain it and use the long period when frequent stress, extend service life; (3) on dust cover body wall, set die parting line, be avoided that the cracking of dust cover inwall when sulfidization molding, improve the quality of dust cover, extend the service life of dust cover, improve the effect of muddy water dust-proof, anti-.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Accompanying drawing labelling: ball pin seal 1, dust cover body wall 2, ball pin seat seal 3, skeleton 4, die parting line circle 5, outer lip 6.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this 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, a kind of open type swing arm dust cover, including ball pin seal 1, dust cover body wall 2 and ball pin seat seal 3, it is provided with, in ball pin seal 1 outer edge upper end, dust cover body wall 2 upper end, the outer lip 6 being shaped as open type, same level direction is uniformly provided with the skeleton 4 of six secondary L-type steels in the port wall rubber at ball pin seal 1 edge, dust cover body wall 2 upper end.
Maximum gauge place on the dust cover body wall 2 outer wall i.e. minimum place of this body wall thickness is provided with die parting line circle 5. This is in motion transmitting procedure, and local is easiest to be deformed, in practice it has proved that, the product sulfidization molding inwall having die parting line is not easy to crack, and the product without die parting line has stealthy cracking mostly, in use, particularly in long-term fierce motor process, product breakage easy to crack.
The cross section of die parting line circle 5 is circular arc type, and die parting line circle 5 and dust cover body wall junction seamlessly transit. Die parting line circle 5 and dust cover body wall 2 are same rubber global formation.
The ball pin seal 1 of dust cover is connected with ball pin, is provided with some dust-proof profile of tooth circles in ball pin seal 1, and profile of tooth circle tooth depth 0.6mm is dust-proof best. Ball pin seat seal 3 is fixed on ball pin seat by clip clamping.
Die parting line circle 5 and dust cover body wall 2 be same rubber, die parting line circle 5 and swing arm dust cover 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 installation is Tong Bu with swing arm dust cover rubber-moulding.
