Abstract
The utility model discloses a car a steering system's bulb shell, including housing body, the housing body upper end is equipped with the through -hole that is used for the linkage ball round pin, and the through -hole outer wall is equipped with the bayonet socket that is used for connecting the dust cover, from top to bottom be equipped with in the housing body bulb that is used for installing the ball seat and by the step axle hole of little shaft hole with macroaxis punch combination one -tenth, the breadth is the hemisphere in the upper portion of staff hole, forms the step between little shaft hole and the big shaft hole, the height that highly is lighter than the ball seat in little shaft hole. Compared with the prior art, the utility model discloses can be used for installing a straight section of thick bamboo ball seat, interior breadth becomes the hemisphere moreover, and when straight ball seat was used in the assurance, ball seat laminating ball was sold, the height that highly is lighter than the ball seat in little shaft hole, put into the cover plate after, guarantee the cover plate and oppress in the ball seat bottom surface rather than in step department always, the extra -oral slope of card is protruding can guarantee the withdrawal force requirement under its big pivot angle behind the installation dust cover.
Description
Technical field
This utility model is related to automobile steering system technical field, the bulb shell of particularly a kind of automobile steering system.
Background technology
Joint, spherical hinge assembly are important parts in automobile steering system, and ball seat is working of plastics, ball seat assembling therein
In bulb inside the shell, existing ball seat has the disadvantage in that ball seat is split-type structural, generally by upper ball base, lower ball base and pad
Piece is assembled, and whole ball seat is outside curved, and this requires that matched bulb enclosure is also curved, and this is just
Bulb shell is made to manufacture difficulty greatly, high cost, it is unfavorable for assembling；And bulb shell upper is used for installing the card of dust cover
Mouth requires because Structure Designing Problem cannot solve the withdrawal force under big swing angle.
Content of the invention
The purpose of this utility model is intended to solve the deficiency of prior art problem, provides a kind of bulb of automobile steering system
Shell.
For reaching above-mentioned purpose, this utility model is to implement according to technical scheme below:
A kind of bulb shell of automobile steering system, including outer cover body, outer cover body upper end is provided with for connecting ball head
The through hole of pin, through hole outer wall is provided with the bayonet socket for connecting dust cover, is from top to bottom provided with for installing in described outer cover body
The step axle hole machine that is bulb and being made up of little axis hole and big axis hole of ball seat, in described little axis hole top, breadth is hemispherical, little
Form step, the height of described little axis hole is less than the height of ball seat between axis hole and big axis hole.
Further, described bayonet socket top is provided with the downward-sloping projection of a circle, and angled protrusions can be after installing dust cover
Ensure that the withdrawal force under its big swing angle requires.
Preferably, described raised angle of inclination is 10-20 degree.
Compared with prior art, this utility model can be used for straight tube ball seat is installed, and interior breadth become hemispherical it is ensured that
During using straight tube ball seat, ball seat laminating ball pin；The height of little axis hole is less than the height of ball seat, it is ensured that cover plate one after putting into cover plate
Vertical compression is under the pressure of ball seat bottom surface rather than at step；Angled protrusions outside bayonet socket can ensure its big swing angle after installing dust cover
Under withdrawal force require.
Brief description
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment is further described to this utility model, in the signal of this utility model
Property embodiment and explanation be used for explaining this utility model, but be not intended as to restriction of the present utility model.
A kind of bulb shell of automobile steering system as shown in Figure 1, including outer cover body 1, outer cover body 1 upper end is provided with
For the through hole 2 of connecting ball head pin, through hole 2 outer wall is provided with the bayonet socket 7 for connecting dust cover, by upper in described outer cover body 1
To having for installing the bulb of ball seat and the step axle hole machine being made up of little axis hole 3 and big axis hole 4, on described little axis hole 3
Breadth hemispherical 6 in portion, form step 5 between little axis hole 3 and big axis hole 4, the height of described little axis hole 3 is less than the height of ball seat
Degree, described bayonet socket 7 top is provided with the downward-sloping projection of a circle 8, and described raised 8 angle of inclination is 10-20 degree, best angle
For 15 degree.
During use, straight tube ball seat is arranged in outer cover body 1, in little axis hole 3, breadth becomes hemispherical it is ensured that using straight tube
During ball seat, ball seat laminating ball pin；The height of little axis hole 3 is less than the height of ball seat, and big axis hole 4 is used for welding cover plate, puts into cover plate
Afterwards it is ensured that cover plate is oppressed always in ball seat bottom surface rather than at step 5；Angled protrusions 8 outside bayonet socket 7 can be dust-proof in installation
Ensure after cover that the withdrawal force under its big swing angle requires.
The technical solution of the utility model is not limited to the restriction of above-mentioned specific embodiment, every according to skill of the present utility model
The technology deformation that art scheme is made, each falls within protection domain of the present utility model.
