Abstract

The invention provides a hub assembly seal which comprises a lip-shaped sealing ring (02) and a combined sealing ring (03) with a dustproof cap. The lip-shaped sealing ring (02) is placed inside a hub (01). A man lip extends towards the interior of the hub (01) and is attached to the shoulder column face of a shaft pipe (04) through a spring (5) in a pressed mode, and an auxiliary lip extends towards the exterior of the hub (01). The combined sealing ring (03) with the dustproof cap is placed outside the hub (01) and comprises the dustproof cap. A main lip extends towards the exterior of the hub and is attached to the shoulder column face of the shaft pipe (04) through a spring (6) in a pressed mode, and an auxiliary lip extends towards the interior of the hub (01). By adoption of the hub assembly seal, it can be ensured that lubricating oil in the hub cannot leak out and muddy water and dust are effectively prevented from entering the interior of the hub, the overall sealing performance of the hub is improved, and the whole hub is unlikely to fail immediately when one sealing ring fails.

Description

Hub assembly is sealed
Technical field
The present invention relates to a kind of automobile hub assembly sealing.
Background technology
Hub bearing generally adopts oil lubrication and grease lubrication two ways.The sealing structure of grease lubrication is relatively simple It is single, but when safeguarding, need to dismantle bearing, cause operating difficulties.And when adopting oil lubrication to safeguard, 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 has higher requirements, and which can be affected 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 present invention is intended to provide a kind of automotive hub assembly sealing of good seal performance.
In order to solve the above problems, the technical solution of the present invention is：A kind of hub assembly sealing, including a lip The combined type packing ring of sealing ring and one with dust cap is constituted, and described lip-type packing is placed on the inside of wheel hub, main lip to Hub interior extends, and is overlayed on the shoulder block cylinder of central siphon by spring, and auxiliary lip extends to the outside of wheel hub；Described band The combined type packing ring of dust cap is placed in the outside of wheel hub, includes dust cap, main lip and extends to the outside of wheel hub, and passes through bullet Spring is overlayed on the shoulder block cylinder of central siphon, and auxiliary lip extends to hub interior.
The invention has the beneficial effects as follows：Lip-type packing can ensure hub interior lubricating oil can not leak, with dust cap Combined type packing ring can effectively prevent the muddy water dust in the external world from entering hub interior, and two seals improve its overall sealing Performance, after a sealing ring fails, whole wheel hub is unlikely to failure at once.

Specific embodiment
Below in conjunction with the accompanying drawings the present invention is described further.
The hub assembly sealing includes a lip-type packing 02, and 03 structure of combined type packing ring with dust cap Into, lip-type packing 02 is adopted on the inside of wheel hub 01, main lip extends to the inside of wheel hub 01, and is overlayed in central siphon 04 by spring 05 Shoulder block cylinder on, bigger its sealing property of hub interior pressure is better, it is ensured that its internal lubrication oil can not leak, at the same auxiliary Lip lip stretches out so that exterior materials can not be entered inside wheel hub 01；The outside of wheel hub 01 adopts 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 employing Double sealing structure, after a sealing ring fails, whole wheel hub is unlikely to failure at once.
