Description
Technical field
The utility model is related to a kind of automobile hub assembly sealing.
Background technology
Hub generally uses oil lubrication and grease lubrication two ways with bearing.The sealing structure of grease lubrication is relatively simple
It is single, but cause operating difficulties, it is necessary to dismantle bearing when safeguarding.And when being safeguarded using oil lubrication, only need to be the lubricating oil in wheel hub
Renew, the advantage makes oil lubrication become the main flow direction of the vehicle hub unit such as truck, car.But oil lubrication is for wheel
The sealing of hub assembly structure is had higher requirements, and it can be influenceed by multinomial factors such as temperature, shock loading, the rigidity of bearing,
Easy oil leakage is ultimately resulted in, so, this just proposes higher requirement to the sealing of the sealing structure of oil lubrication hub assembly, existing
Hub assembly sealing it is unsatisfactory.
The content of the invention
For deficiency of the prior art, the automotive hub assembly that the utility model aims to provide a kind of good seal performance is close
Envelope.
In order to solve the above problems, technical solution of the present utility model is：A kind of hub assembly sealing, including one
Lip-type packing and a combined type packing ring with dust cap are constituted, and described lip-type packing is placed on the inside of wheel hub, main lip
Mouth extends to hub interior, and is overlayed by spring on the shoulder block cylinder of central siphon, aids in lip to extension outside wheel hub；It is described
The combined type packing ring with dust cap be placed in the outside of wheel hub, include dust cap, main lip to extending outside wheel hub, and lead to
Cross spring to overlay on the shoulder block cylinder of central siphon, auxiliary lip extends to hub interior.
The beneficial effects of the utility model are：Lip-type packing can ensure that hub interior lubricating oil can not leak, with dust-proof
The combined type packing ring of lid can effectively prevent the muddy water dust in the external world from entering hub interior, and two seals improve its entirety
Sealing property, after a sealing ring failure, whole wheel hub is unlikely to fail at once.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment；
Fig. 2 is Fig. 1 of embodiment of the present invention partial enlarged drawing；
In figure：01st, wheel hub, 02, lip-type packing, 03, the combined type packing ring of dust cap, 04, o type sealing rings, 05, bullet
Spring, 06, spring.
Embodiment
The utility model is described further below in conjunction with the accompanying drawings.
Hub assembly sealing includes a lip-type packing 02, and a structure of combined type packing ring 03 with dust cap
Into the inner side of wheel hub 01 uses lip-type packing 02, and main lip is overlayed in central siphon 04 to extension inside wheel hub 01 by spring 05
Shoulder block cylinder on, hub interior pressure is bigger, and its sealing property is better, it is ensured that its internal lubrication oil can not leak, simultaneously aid in
Lip lip stretches out so that exterior materials can not enter inside wheel hub 01；The outside of wheel hub 01 uses combined type packing ring, should
Combined type packing ring contains a dust cap, can effectively prevent the muddy water dust in the external world from entering inside wheel hub 01, while its
Internal lip-type packing also has ibid the same major-minor bead structure, improves its overall sealing property.It is additionally, since use
Double sealing structure, after a sealing ring failure, whole wheel hub is unlikely to fail at once.
Claims (1)
