Description
Technical field
Automobile spherical hinge structure design field is the utility model is related to, more particularly, to a kind of automobile ball of moment optimization
Hinged structure.
Background technology
Existing automobile spherical hinge structure is after by theoretical calculation and verification experimental verification, the rotation in automobile ball pivot work torque
Torque is greater than shaking moment, and rotating torque includes rotating staring torque and rotation work torque, and rotates staring torque especially
Greatly.Thus necessarily cause existing automobile spherical hinge structure to meet the requirement of shaking moment, while can not also reduce rotation and open
Difference between kinetic moment and shaking moment, rotation work torque and shaking moment；And rotating torque (including rotate startup power
Square) have a significant impact to handling, the sensitivity of automobile steering system, therefore, cause startup and the fortune of automobile steering system
Capable sensitivity reduces, and the handling of automobile steering system also declines therewith.
Utility model content
The technical problems to be solved in the utility model is：A kind of the problem of existing for prior art, there is provided moment optimization
Automobile spherical hinge structure, reduce the difference between rotating torque and the shaking moment in the work of automobile ball pivot, improve motor turning
The sensitivity of system.
The technical problems to be solved in the utility model is realized using following technical scheme：A kind of automobile ball of moment optimization
Hinged structure, including ball pin, ball pin seat and ball pin set, described ball pin seat are arranged in ball pin set inner chamber, the bulb of the ball pin
Sphere friction pair is formed between portion and ball pin seat internal chamber wall, groove is set on the internal chamber wall of the ball pin seat, the groove is circle
Arc groove, and the diameter of groove passes through the centre of sphere of ball pin seat inner chamber.
Preferably, described groove is the annular through groove of global key seat internal chamber wall.
Preferably, described groove sets some.
Preferably, described groove is arranged in parallel.
Preferably, the intracavity bottom of the ball pin seat is planar structure, and the groove and ball pin seat inner chamber baseplane phase
It is mutually parallel.
Compared with prior art, the beneficial effects of the utility model are：In the ball pivot course of work, the ball head of ball pin with
Sphere friction pair is formed between ball pin seat internal chamber wall, by setting arc groove on the internal chamber wall of ball pin seat, and the arc groove
Diameter passes through the centre of sphere of ball pin seat inner chamber, when ball pin rotates in ball pin seat inner chamber, under conditions of pretightning force is certain, and ball pin
Ball head and ball pin seat internal chamber wall between the lifting surface area of contact surface reduce, ball pin pivoting friction torque integral area is corresponding
Ground is reduced, and then its pivoting friction torque is also reduced；Simultaneously as the arc groove set on the internal chamber wall of the ball pin seat is also
Oil storage tank is served as, further reduces coefficient of friction.Therefore, reduce the rotating torque in the work of automobile ball pivot, and then contract
Small difference between rotating torque and shaking moment, add startup and the operation sensitivity of automobile steering system.

Fig. 2 is the partial enlarged drawing at A in Fig. 1.
Fig. 3 is the sectional view of the ball pin seat in Fig. 1.
Component token name claims in figure：1- ball pins, 2- ball pin seats, 3- ball pin sets, 4- grooves.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with the accompanying drawings and specifically
The utility model is described in detail embodiment.It should be appreciated that specific embodiment described herein is only explaining this
Utility model, it is not used to limit the utility model.
A kind of automobile spherical hinge structure of moment optimization as shown in Figure 1 and Figure 2, mainly include ball pin 1, ball pin seat 2 and ball pin
Set 3, described ball pin seat 2 are arranged on ball pin and covered in 3 inner chambers, formed between the ball head and the internal chamber wall of ball pin seat 2 of the ball pin 1
Sphere friction pair, groove 4 is set on the internal chamber wall of ball pin seat 2, and the groove 4 is arc groove, and the diameter of groove 4 passes through ball
The centre of sphere of the inner chamber of key seat 2, as shown in Figure 3.
For ball pin seat 2 therein and its groove 4, injection molding can be used to produce, manufacture difficulty is low, and processing is fast
It is prompt, it is easy to accomplish to produce in enormous quantities, advantageously reduce the processing cost of ball pin seat 2.Preferably, as shown in figure 3, described groove
4 be the annular through groove of the global internal chamber wall of key seat 2.Further, described groove 4 can set some.Further, it is described
Groove 4 can be arranged in parallel.Further, when the intracavity bottom of ball pin seat 2 is planar structure, the groove 4
It is also designed to be parallel to each other with the inner chamber baseplane of ball pin seat 2.It is pointed out that the tool of the groove 4 in the ball pin seat 2
Body sets number to need according to the intensity of the work torque of specific ball pivot and ball pin seat 2 progress finite element optimum design, with up to
Required to corresponding.
The utility model is simple in construction, and manufacture difficulty is small, it is easy to accomplish produce in enormous quantities, it is therefore, cost-effective.In ball pivot
In the course of work, due to being provided with the groove 4 of arc structure on the internal chamber wall of ball pin seat 2, and the diameter of the groove 4 passes through ball pin
The centre of sphere of the spherical inner chamber of seat 2, therefore, when ball pin 1 rotates in the inner chamber of ball pin seat 2, under conditions of pretightning force is certain, ball
The lifting surface area of contact surface between the ball head and the internal chamber wall of ball pin seat 2 of pin 1 will be reduced, so that the rotation friction of ball pin 1
Square integral area is correspondingly reduced, and then its pivoting friction torque is also reduced；Simultaneously as the internal chamber wall of the ball pin seat 2
