Abstract
The utility model relates to a sealing structure of a hub bearing. The sealing structure of a hub bearing consists of an elastic herringbone framework type rubber sealing element and an elastic L-shaped framework type rubber sealing element that are combined together. The elastic herringbone framework type rubber sealing element and the elastic L-shaped framework type rubber sealing element have an elastic fastening connection structure. As for the sealing structure of the hub bearing, the combined sealing structure arranged between an outer ring and a spindle ensures the tightness of a vehicle hub bearing, so that the service life of the hub bearing is prolonged and the problem that the tightness of the existing vehicle hub bearing is poor is solved. The sealing structure of the hub bearing has the characteristics of being good in tightness, convenient in installation and repair, low in manufacturing cost and long in service life.
Description
Technical field
The utility model relates to a kind of sealing configuration of hub bearing, belongs to the hub bearing product technical field of using on the wheel shaft of automobile front and back.
Background technique
The present hub bearing that before and after automobile, uses on the wheel shaft, mainly comprise outer ring, mandrel, sealing configuration and rolling bearing, between outer ring, mandrel, be provided with a sealing configuration, the sealing structure is mainly used in anti-sealing or other liquid enters in the hub bearing, after anti-sealing or other liquid enter hub bearing rolling bearing is caused adverse effect.Therefore the quality of sealing structural behaviour directly has influence on the hub bearing usability, what use on the hub bearing of vehicle at present mainly is the annular seal structure, the Sealing of this annular seal structure is owing to be monolithic construction, after using certain hour, vehicle will wear and tear, after wearing and tearing, owing to lack effective deformation-compensated effect, sealability will reduce, therefore be easy to make the hub bearing water inlet or enter other liquid, will influence the working life of hub bearing like this.
Summary of the invention
The utility model provides a kind of sealing configuration of a kind of hub bearing of novelty, adopt the deformable compensation sealing structure technology of man type elastic skeleton formula rubber seal and L shaped elastic skeleton formula rubber seal combination, to realize guaranteeing the purpose of vehicle hub bearing seal performance.
The technical solution adopted in the utility model is:
A kind of sealing configuration of hub bearing, the sealing configuration of described hub bearing is constituted by man type elastic skeleton formula rubber seal and L shaped elastic skeleton formula rubber seal, and man type elastic skeleton formula rubber seal and L shaped elastic skeleton formula rubber seal are the elasticity structure that is fastened and connected.
The utility model beneficial effect is:
Owing to adopted the sealing configuration of a kind of hub bearing of the present utility model, between outer ring and mandrel, combined sealing structure is set, guaranteed vehicle hub bearing seal, thereby improved the working life of hub bearing, solved the problem of existing vehicle hub bearing seal difference, the sealing configuration of a kind of hub bearing of the present utility model has: the characteristics of good seal performance, installation and maintenance convenience, low cost of manufacture, long service life.

Embodiment
As Fig. 1, Fig. 2, shown in Figure 3.
A kind of hub bearing comprises: rolling bearing, outer ring 1, mandrel 2, sealing configuration 3 structures.
A kind of sealing configuration of hub bearing, the sealing configuration of described hub bearing is constituted by man type elastic skeleton formula rubber seal and L shaped elastic skeleton formula rubber seal, and man type elastic skeleton formula rubber seal and L shaped elastic skeleton formula rubber seal are the elasticity structure that is fastened and connected.
Basic functional principle:
Press Fig. 1, Fig. 2, shown in Figure 3, man type elastic skeleton formula rubber seal and L shaped elastic skeleton formula rubber seal elasticity is fastened and connected is assembled into sealing configuration 3, then sealing configuration 3 is installed in the structure between outer ring 1 and the mandrel 2, and other component are gone up in assembling, constitute hub bearing, hub bearing is installed on the vehicle, and mounting vehicle tire on hub bearing so just can use then.
Vehicle is in daily use, when sealing configuration 3 weares and teares to some extent, because man type elastic skeleton formula rubber seal and L shaped elastic skeleton formula rubber seal are that elasticity is fastened and connected, so have the function that expands outwardly, can play the compensating action of Sealing when wearing and tearing like this, guaranteed the reliability of sealing configuration 3, thus the working life of having improved hub bearing.
Claims (1)
1. the sealing configuration of a hub bearing, it is characterized in that: the sealing configuration of described hub bearing is constituted by man type elastic skeleton formula rubber seal and L shaped elastic skeleton formula rubber seal, and man type elastic skeleton formula rubber seal and L shaped elastic skeleton formula rubber seal are the elasticity structure that is fastened and connected.
