Abstract
The utility model discloses a cam for automobile steering system, it includes a cam body, and the cam body is the disk structure, and the cam body includes quotation and footing, quotation and footing integrated into one piece, and quotation bottom downwardly extending extends a plurality of boss, and the boss uses the footing as the center along quotation annular distribution in quotation bottom, and it has the slot to open at the quotation top that the boss corresponds the position. The utility model discloses be favorable to the shaping at the powder metallurgy in-process, and density distribution is even.
Description
Technical Field
The utility model relates to an automobile parts technical field specifically is cam for the automobile steering system.
Background
At present, the automobile steering gear face cam is one of key parts used in an automobile steering system, and is used for adjusting the height and the position of an automobile steering wheel and locking the adjusted position. The requirements of the dimensional accuracy and the form and position tolerance accuracy of the product are strict, the product cannot be produced by adopting the traditional machining method, the traditional powder metallurgy method is usually adopted, but the accuracy cannot be ensured, and the density of the product is usually lower because the boss on the cam is thicker in the position during the compression process of the powder metallurgy.
Disclosure of Invention
The utility model discloses the technical problem that will solve is: provided is a cam for an automobile steering system, which is advantageous to molding in a powder metallurgy process and has uniform density distribution.
The utility model adopts the technical proposal that: the cam for the automobile steering system comprises a cam body, wherein the cam body is of a disc-shaped structure and comprises a disc surface and bottom feet, the disc surface and the bottom feet are integrally formed, a plurality of bosses downwards extend from the bottom of the disc surface, the bosses are distributed at the bottom of the disc surface along the disc surface in an annular mode by taking the bottom feet as centers, and grooves are formed in the top of the disc surface at the positions corresponding to the bosses.
Preferably, the number of lands is four, and correspondingly, the number of grooves is also four.
Preferably, the depth of the grooves is no greater than the thickness of the disk surface.
Preferably, the grooves are shaped like lands in plan view.
After the structure more than adopting, compared with the prior art, the utility model has the following advantage: cam body quotation is equipped with the boss usually, and the boss has certain thickness, and it forms great difference in height with the quotation, consequently has the inhomogeneous phenomenon of density at its in-process of powder metallurgy suppression, and the utility model discloses open the slot that has corresponding shape on the boss corresponds the quotation for the quotation thickness at boss place reduces correspondingly, thereby makes the boss place obtain density and other position density of cam quotation keep unanimous at powder metallurgy in-process, avoids causing the inhomogeneous problem of cam density, still is favorable to the shaping simultaneously.
Drawings
Fig. 1 is a side view of the structure of the present invention.
Fig. 2 is a top view of the structure of the present invention.
The cam comprises a cam body 1, a cam body 2, a disc surface 3, a bottom foot 4, a boss 5 and a groove.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the following detailed description.
The utility model provides a cam for automobile steering system, as shown in fig. 1, it includes a cam body 1, cam body 1 is the disc structure, cam body 1 includes quotation 2 and footing 3, quotation 2 and footing 3 integrated into one piece, 2 bottoms downwardly extending of quotation extend a plurality of boss 4, as shown in fig. 2, boss 4 quantity is four, correspondingly, 5 quantity of slot also is four, boss 4 uses footing 3 to distribute in 2 bottoms along 2 rings of quotation as the center, 2 tops of quotation that correspond the position at boss 4 are opened there is slot 5, and the slot 5 degree of depth is not more than 2 thicknesses of quotation, make quotation 2 have certain thickness. In addition, the shape of the groove 5 is the same as that of the boss 4 when viewed from above, so that the cam body 1 can be easily molded and released.
While the above is directed to the preferred embodiment of the present invention, it is not intended that it be limited, except as by the appended claims. The present invention is not limited to the above embodiments, and the specific structure thereof allows for changes, all the changes made within the protection scope of the independent claims of the present invention are within the protection scope of the present invention.
