Abstract
The utility model discloses an automobile lower swinging arm ball stud connecting structure, which resolves the problems that the ball stud is easy to break during actual use of a current automobile lower swinging arm ball stud connecting structure, with influence on the normal travel operation of the automobile, with the following structure: an automobile lower swinging arm ball stud connecting structure, comprising a ball stud and a lower swinging arm, where the ball stud comprises a rod body and a ball body integrated to each other; the ball body is connected with the lower swinging arm; a positioning groove is disposed on the outer circumference of the rod body, characterized by that the positioning groove is allocated along a tangential direction of the outer circumference of the rod body.
Description
Technical field
The utility model relates to swing arm under a kind of automobile, relates in particular to swing arm ball pin connected construction under a kind of automobile.
Technical background
Under the automobile swing arm normally be used for car brake on steering swivel link owing to need down the transmission of relative motion and power between swing arm and this steering swivel, between them, be provided with the ball pin.The structure of ball pin comprises the body of rod and the spheroid that is connected as a single entity, and wherein spheroid is assemblied in down in the set spherical pit in swing arm end, and the body of rod is plugged in the described steering swivel.In order to realize the stability to axial between the body of rod and the steering swivel, be provided with circular positioning groove in the corresponding position of body of rod outer peripheral face, steering swivel is provided with positioning screw hole, and fixing screw is inserted in this hole, and, the ball pin is fixed by ball pin rod body ring-type positioning groove.The ball pin of this structure has following defective in the use of reality: at first, the annular positioning groove that is provided with has reduced the actual radial dimension of the body of rod to a great extent, the ball pin need adopt the expensive higher material of intensity of price, otherwise in the use of reality, be prone to the stress concentration phenomenon, the body of rod can be from the position fracture of positioning groove, the traffic safety of entail dangers to vehicle.Secondly, the setting of circular positioning groove makes that also the ball pin can be with respect to fixing screw generation circumferential rotation by a relatively large margin, and this is unfavorable for the stable delivery of power between described steering swivel and the following swing arm.
Summary of the invention
For overcoming the above-mentioned defective that swing arm ball pin connected construction is had under the existing automobile, the utility model technical issues that need to address are: swing arm ball pin connected construction under a kind of later-model automobile is provided, it is in the practical work process of automobile, ball pin rod body does not need the material that adopts the intensity that costs an arm and a leg higher, ball pin rod body is difficult for occurring in the phenomenon of rupture of positioning groove position, has stability preferably for the transmission of descending power between swing arm and the steering swivel.
For solving the problems of the technologies described above, the technical solution of the utility model: swing arm ball pin connected construction under a kind of automobile, comprise ball pin and following swing arm, the ball pin comprises the body of rod and the spheroid that is connected as a single entity, spheroid is connected with following swing arm, body of rod outer peripheral face is provided with positioning groove, it is characterized in that, described positioning groove is arranged along body of rod outer circumference surface tangential direction.Under the utility model automobile in the swing arm ball pin connected construction positioning groove of ball pin rod body be a straight trough, be arranged on prejudicially on the outer peripheral face of the body of rod, fixing screw is inserted in the positioning screw hole on the car brake steering swivel, and pass through ball pin rod body groove under the qualification effect of fixing screw, the ball pin both can have been realized the stability on the body of rod axial direction, can realize stablizing on the circumferential direction again.
As preferably, described positioning groove is along curved perpendicular to the cross section of its length direction.The described cross section of positioning groove is curved, is convenient to realize cooperating between positioning groove and the fixing screw, has made things convenient for assembling.
As preferably, described positioning groove along perpendicular to its rectangular degree to the cross section c-shaped.This cross section is c-shaped, has made things convenient for body of rod surface shaping positioning groove.
Therefore, the beneficial effects of the utility model:
Because positioning groove set on the outer peripheral face of ball pin rod body is arranged along the tangential direction of body of rod outer peripheral face, this positioning groove is non-enclosed straight trough, with respect to enclosed circular positioning groove, this non-enclosed positioning groove is less relatively to the radial dimension influence of the body of rod, the body of rod has the higher anti-intensity that fractures, the ball pin does not need the material of using the intensity that costs an arm and a leg higher, help saving productive costs, and the reliability of service of ball pin can be guaranteed also.Described positioning groove is a straight trough, and under the qualification effect of fixing screw, the ball pin can not have circumferential rotation with respect to fixing screw, helps the stability that the ball pin transmits power.
Description of drawings
Accompanying drawing 1 is the local structure cutaway view of swing arm ball pin connected construction under the utility model automobile.
The specific embodiment
See accompanying drawing, swing arm ball pin connected construction comprises swing arm 1 down, ball pin 2 under the utility model automobile.Ball pin 2 comprises the body of rod 3 and spheroid 5, and spheroid 5 is connected an end of the body of rod 3, and both are connected as a single entity.
End in swing arm 1 down is provided with spherical pit, and the spheroid 5 on the described ball pin 2 is connected in this spherical pit.
The described body of rod 3 be used for car brake on steering swivel link, in order to guarantee connection stability between the two, on the body of rod 3 of ball pin 2, be provided with positioning groove 4, this positioning groove 4 is along arranging on the tangential direction of the body of rod 3 outer circumference surfaces.This positioning groove 4 generally is to be formed on the outer peripheral face of the body of rod 3 by the mode that milling is processed, and it is a non-enclosed straight trough.Positioning groove 4 along perpendicular on its length direction the cross section curved, for consideration easy to process, this cross sectional shape can be preferably c-shaped.
Claims (3)
1, swing arm ball pin connected construction under a kind of automobile, comprise ball pin (2) and following swing arm (1), ball pin (2) comprises the body of rod (3) and the spheroid (5) that is connected as a single entity, spheroid (5) is connected with following swing arm (1), the body of rod (3) outer peripheral face is provided with positioning groove (4), it is characterized in that described positioning groove (4) is arranged along the body of rod (3) outer circumference surface tangential direction.
