Abstract
The utility model discloses an automobile ball pin assembly which comprises a ball pin seat (1). A straight hole (2) is arranged on a plate rib face of the ball pin seat (1). The ball pin seat (1) is connected with a swing arm (15) through a pressed bolt (12) of the swing arm (15) and a mounting nut (13) matched with the pressed bolt (12), wherein the pressed bolt (12) is communicated with the straight hole (2) and the swing arm (15). A screw (17) of the pressed bolt (12) is provided with a straight thread (14) which is in interference fit with a screwed hole and is arranged along the axial direction of the screw. Due to the fact that the pressed bolt is pressed into the straight hole (2) by atmospheric pressure, the automobile ball pin assembly has the advantages of effectively reducing a gap between the plate rib face of the ball pin seat and the bolt, prolonging service life of the ball pin assembly, and at the same time reducing work intensity of workers in installation. The automobile ball pin assembly is applicable to a steering system of any vehicle.
Description
Technical field
The utility model belongs to automotive field, relates to the device that a kind of Vehicular turn is used, specifically a kind of automobile ball pin assembly.
Background technology
At present, the ball pin assembly structure that motor turning of the prior art is used as shown in Figure 1: be provided with 2-4 tapped bore 2-1 at ball pin seat 1-1, tapped bore 2-1 links together by the swing arm on the bolt, nut and the chassis that are mated.But because the contact surface of ball pin seat 1-1 and bolt is black skin, contact surface after bolt and ball pin seat 1-1 install has the space, it is bad to cause ball pin plate muscle face and bolt joint face to be fitted, therefore along with the vehicle later stage uses, the space between steering ball pin plate muscle face and the bolt is slowly increased, finally cause the ball pin component wear, the reliability of ball pin assembly reduces, also decrease service life, makes the fault rate of vehicle improve serious harm driver's personal safety.
The utility model content
Be to solve the total deficiency that exists of prior art, the utility model provides a kind of automobile ball pin assembly that can reduce space, the raising service life between ball pin seat board muscle face and the bolt contact surface.
For achieving the above object, the automobile ball pin assembly that the utility model is related, comprise the ball pin seat, be provided with straight hole on the plate muscle face of described ball pin seat, press mounting bolt by connecting straight hole and swing arm of described ball pin seat and swing arm, link to each other with mounting nuts that press mounting bolt cooperates, be provided with on the screw rod of described press mounting bolt with the straight hole interference fit, along the straight burr section of screw axial setting.
As the restriction to aforesaid way: described straight burr section is near the nut setting.
As the further restriction to aforesaid way: described ball pin seat inside is provided with the ball cover that holds steering ball, be arranged on the bottom that the ball cover bottom is connected with the bottom of ball pin seat simultaneously.
Adopt as above technical scheme, its effect is:
(1) press mounting bolt is provided with straight burr section, is press fit in the straight hole of ball pin panel seat plate muscle face by bar pressure during installation, makes the straight hole of press mounting bolt and ball pin seat realize interference fit, reduces the gap between ball pin seat muscle face and the press mounting bolt.The mounting hole of swing arm is passed in the other end of press mounting bolt, and pin with mounting nuts and to be fixed on the binding face of swing arm, strengthened the applying degree of press mounting bolt and ball pin seat muscle face, reduced the gap between press mounting bolt and the ball pin seat muscle face, actv. has guaranteed stability and the turning efficiency of ball pin assembly in the car load operational process, has prolonged simultaneously the service life of ball pin assembly;
(2) adopt the bolt connection ball pin assembly of press mounting structure and the labour intensity that swing arm has reduced the staff.
As fully visible, the utility model can effectively reduce the gap between ball pin seat and the bolt binding face.The utility model is applicable to the steering hardware of any vehicle.
