Abstract
The utility model provides a novel hub oil seal characterized by comprising a primary framework, a secondary framework, a spring and a sealing lip structure, wherein the primary framework and the secondary framework are assembled into a whole by spinning; the spring is mounted at a groove on the inner side of the sealing lip structure; and the sealing lip structure is vulcanization-molded on the primary framework. The utility model has the advantage of compact structure; the structure of the exposed frameworks and the novel sealing lip structure can achieve good effects of heat dissipation and sealing; and the sealing lip structure is supported by both the primary framework and the spring, the inner ring of a bearing can be detached along with the secondary framework when the hub is detached, thus preventing the sealing lip from being scratched by the inner ring and making the assembly and disassembly more convenient.
Description
Technical field
The utility model belongs to the technical field of automobile front axle assembly, particularly the novel hub oil sealing.
Background technique
Tradition hub oil seal thermal diffusivity is relatively poor, does not possess the renitency performance, can not be in the dismounting wheel hub with the bearing inner race band under, cause oil seal lip by the inner ring scratch, oil seal failure, the oil sealing that need more renew increases maintenance cost.
Summary of the invention
The utility model purpose provides a kind of novel hub oil sealing.
The technical solution of the utility model is achieved in that
The novel hub oil sealing is characterized by: it is made up of main framing, secondary skeleton, spring and sealing lip structure, and main framing, secondary skeleton spinning are assembled together, and spring is installed in oil sealing procheilon structure inboard groove place, and sealing lip structure sulfidization molding is on main framing.
The utlity model has compact structure, the sealing lip structure that exposes skeletal structure and novelty can play good heat radiation and seal action, main framing supports the sealing lip structure with spring, secondary skeleton can be in the dismounting wheel hub with the bearing inner race band under, prevent oil seal lip by the inner ring scratch, improve easy accessibility.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of installing and using of the present utility model.
Specific embodiments
Describe specific embodiments of the present utility model in detail below in conjunction with accompanying drawing.
