Abstract
The utility model provides a can easier relative pivoted bulb structure between bulb and the bulb seat, including bulb seat and the connecting axle of connection in bulb seat one side, be provided with the vertical logical chamber of lining up the bulb seat in the bulb seat, the wall that leads to the chamber includes the face of cylinder and sphere from bottom to top in proper order, connection position smooth transition between the face of cylinder and the sphere, the central line on the centre of sphere process face of cylinder of sphere, be equipped with connecting portion in the one end of being close to face of cylinder place on the bulb seat, be equipped with the screw hole in the one end of keeping away from the bulb seat on the connecting axle.
Description
Technical field
The utility model relates to vehicular spare parts field, is specifically related to a kind of ball head structure.
Background technology
Ball joint is for connecting motor turning direction device and wheel flutter, between deflector and track arm, with tire up-and-down movement, by rotation and the swing of ball pin, the steering-wheel effort of bearing circle is transferred to tire, realization turns to, and is one of crucial accessory of automobile steering system, and the quality and performance of ball joint directly affects stationarity and the safety of running car.In existing vehicle suspension ball head, the bulb close-fitting of ball end is arranged in ball cap, and often occurring in use procedure, because close-fitting degree to cause between bulb and ball cap problem in relative rotation not, affects transmission stability between steering direction device and wheel flutter.
Summary of the invention
Technical problem to be solved in the utility model is to provide can easier ball head structure in relative rotation between a kind of bulb and ball cap.
For solving above-mentioned existing technical matters, the utility model adopts following scheme: a kind of ball head structure, comprise ball cap and the adapter shaft being connected to ball cap side, the cavity of vertical through ball cap is provided with in ball cap, the wall of described cavity comprises the face of cylinder and sphere from bottom to top successively, connecting portion between the described face of cylinder and sphere seamlessly transits, the line of centers of the centre of sphere through the face of cylinder of described sphere, described ball cap is provided with connecting portion in the one end near place, the face of cylinder, described adapter shaft is provided with tapped bore in the one end away from ball cap.
As preferably, the central axis of described tapped bore, in the line of centers on the face of cylinder, has spacing between the line of centers of shown tapped bore and the line of centers on the face of cylinder.
As preferably, described connecting portion is annular protrusion.
As preferably, described ball cap is formed around the cavity concave surface of a week in the edge indent of cavity at one end end face deviating from connecting portion.
Beneficial effect:
After the utility model adopts technique scheme, this ball head structure is arranged to comprise the face of cylinder and sphere successively from bottom to top by the wall of the cavity by ball cap, when the pommel of ball end is contained in cavity, only part surface contacts completely with sphere, remainder is in the scope that the face of cylinder surrounds, pommel due to ball end is spheroid, therefore remainder not with Cylindrical Surfaces Contact, ball end is so just made easierly to rotate relative to ball cap, ball cap is provided with connecting portion in the one end near place, the face of cylinder, being mainly used in location ball end makes ball end spacing in cavity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the cutaway view at A-A place in Fig. 1.
Detailed description of the invention
Be the preferred embodiment of a kind of ball head structure of the utility model as illustrated in fig. 1 and 2, its adapter shaft 2 mainly comprising ball cap 1 and be connected to ball cap 1 side, the cavity 3 of vertical through ball cap is provided with in ball cap 1, the wall of cavity 3 comprises the face of cylinder 31 and sphere 32 from bottom to top successively, connecting portion between the face of cylinder 31 and sphere 32 seamlessly transits, the line of centers of the centre of sphere through the face of cylinder 31 of sphere 32, ball cap 1 is provided with connecting portion 4 in the one end near place, the face of cylinder 31, adapter shaft 2 is provided with tapped bore 5 in the one end away from ball cap 1.In this embodiment, connecting portion 4 is an annular protrusion, and it is by internal face and other link interference fit.The central axis of tapped bore 5, in the line of centers on the face of cylinder 31, has spacing between the line of centers of shown tapped bore 5 and the line of centers on the face of cylinder 31.Ball cap 1 is formed around the cavity concave surface of 3 one weeks 6 in the edge indent of cavity 3 at one end end face deviating from connecting portion 4.
This ball head structure is arranged to comprise the face of cylinder and sphere successively from bottom to top by the wall of the cavity by ball cap, when the pommel of ball end is contained in cavity, only part surface contacts completely with sphere, remainder is in the scope that the face of cylinder surrounds, pommel due to ball end is spheroid, therefore remainder not with Cylindrical Surfaces Contact, ball end is so just made easierly to rotate relative to ball cap, ball cap is provided with connecting portion in the one end near place, the face of cylinder, is mainly used in location ball end and makes ball end spacing in cavity.
