Description
Technical field
The utility model relates to a kind of automobile hub.
Background technology
Automobile hub plays very vital function in car load, when automobile hub lost efficacy, slightly can produce noise, and severe can produce that car load rocks, locking problem, and consequence is very serious.In existing structure, automobile hub outer face directly assembles with block, and by dimensional fits, block and automobile hub outer face are fitted.This laminating requires that the precision prescribed of automobile hub and block is high, and face cooperation easily produces gap, water inlet.
Summary of the invention
The technical problems to be solved in the utility model is to provide the strong automobile hub of a kind of water resistance.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: be provided with the annular groove that cross-sectional plane is rectangle around the axis hole on the body of described automobile hub, seal ring is provided with in described annular groove, the width of described seal ring is greater than the degree of depth of annular groove, the cross-sectional plane of described seal ring comprises semi-circular portion and rectangle part, described body is provided with expansion slot, and described expansion slot is positioned at annular groove both sides.
As preferably of the present utility model, the body of described automobile hub is provided with two annular grooves, and two annular grooves are on identical home position, are provided with seal ring in each annular groove, and the width of described seal ring is greater than the degree of depth of annular groove.
The utility model adopts technique scheme: after the outer face of automobile hub and block are fitted, between outer face and block, gap is filled up automatically by seal ring, automobile hub inside and external environment; Can effective water resistance, improve reliability and the life-span of automobile hub.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described in detail.
Fig. 1 is the structural representation of a kind of automobile hub of the utility model;
Fig. 2 is the partial enlarged drawing of Fig. 1 at A place.
Detailed description of the invention
As shown in Figure 1, 2, be provided with the annular groove 2 that two cross-sectional planes are rectangle around the axis hole on the body 1 of this automobile hub, the center of circle of annular groove 2 is positioned on the line of centers of axis hole, and two annular grooves 2 are on identical home position.Seal ring 3 is provided with in each annular groove 2; The width of seal ring 3 is greater than the degree of depth of annular groove 2, can guarantee that seal ring 3 protrudes on body 1 like this.The cross-sectional plane of described seal ring 3 comprises semi-circular portion and rectangle part, described body is provided with expansion slot 4, described expansion slot 4 is positioned at annular groove both sides, four volume expansion slot 4 are just provided with like this on body 1, the cross-sectional plane of expansion slot 4 is arc, after protrusion seal ring 3 on body 1 is extruded, seal ring 3 variant part branch is embedded in expansion slot 4, greatly can increase and decrease the connection area between seal ring 3 and body like this, thus improves sealing effectiveness.
