Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.It should be appreciated that detailed description of the invention described herein is merely to illustrate and explains the present invention, it is not limited to the present invention.
In the present invention, when not making contrary explanation, " top, the end, inside and outside " etc. are included in the noun of locality in term and only represent this term orientation under normal service condition, or for being commonly called as of skilled artisan understands that, and it is not construed as the restriction to this term.
The invention provides the ball seat of a kind of automobile ball pin control arm, ball seat open top concave downward are formed with accommodation chamber, it is specifically shown in Fig. 3 and Fig. 4, the sidewall of this ball seat from top to bottom includes vertical section 1, neck section 2 and extension 3 successively, vertical section 1 and extension 3 be positioned at the two ends of neck section 2 and stretch out so that neck section 2 be externally formed with groove；The side of extension 3 from bottom to top includes inclined-plane 4 and plane.
The ball seat of above-mentioned automobile ball pin control arm includes vertical section 1, neck section 2 and extension 3, by arranging inclined-plane 4 in the extension 3 (i.e. ball seat pendulum mouth place) of ball seat, the distortion allowance at pendulum mouth place is increased, and then the tensile strength at pendulum mouth place and the deformation basal area of ball seat are increased, so can either meet the requirement increasing pivot angle, the pull-out force of ball pin can be improved again, finally make the automobile ball pin control arm prepared and ball seat thereof be respectively provided with the safety of excellence and excellent service life.
In the present invention, the inclined degree on inclined-plane 4 can select in wide scope, although the inclined degree on inclined-plane 4 is more serious more can improve the tensile strength putting mouth place, but consider from the overall mechanical strength of ball seat, avoid the pulling force that inclined-plane 4 receives neck section 2 can be caused excessive pressure, preferably, the acute angle formed between inclined-plane 4 and plane is 15-45 °.So, inclined-plane 4 can either improve the tensile strength at pendulum mouth place, enables to again neck section 2 and extension 3 cooperates to improve the overall mechanical strength of ball seat.
In the present embodiment, inclined-plane 4 can select in the same manner as the area ratio of plane in wide scope, but meeting on the basis of tensile strength at raising pendulum mouth place, inclined-plane 4, make extension 3 can provide the latching force of fastening for being positioned at the ball pin holding chamber simultaneously, preferably, inclined-plane 4 is 3-5:1 with the area ratio of plane.Thus, the face of the top of the section of will extend over 3 is set to plane and can be effectively improved again thickness topmost and then improve mechanical strength herein such that it is able to make the extension 3 can firmly snap close ball pin.
In addition, also it is can change in wide scope about the aspect ratio between vertical section 1, neck section 2 and extension 3, it it is similarly the overall mechanical strength in order to improve ball seat, preferably, along vertical direction, the aspect ratio drawing together vertical section 1, neck section 2 and extension 3 is 1:0.1-0.2:0.2-0.25.This aspect ratio is the aspect ratio that applicant obtains by constantly groping, and under this aspect ratio, the sidewall of ball seat can give the coupling mechanism force maximum with ball pin.
Additionally, the concrete structure holding chamber can also select in wide scope, as long as ball pin can provide stable coupling mechanism force and ball pin pull-out force just may be used, but in order to improve coupling mechanism force and the ball pin pull-out force of ball seat further, preferably, the revolution body cavity that chamber from bottom to top includes cylindrical cavity successively and aperture is upwards shunk gradually is held；Wherein, turn round the axis of body cavity and the dead in line of cylindrical cavity, and turn round the curve that bus is evagination of body cavity.The revolution body cavity at such top can by ball pin stably snap close in holding intracavity.
In the above-described embodiment, so that the structure held between each several part of chamber is more stable, it is therefore desirable to coordinate by between the sidewall each several part of ball seat, it is preferable that, cylindrical cavity is enclosed by vertical section 1 and forms, and revolution body cavity is enclosed by neck section 2 and extension 3 and forms.So just the tensile strength at the pendulum mouth place of ball seat can be coordinated closely with the coupling mechanism force holding chamber, improve the overall mechanical strength of ball seat with this.
On the basis of the above, in order to strengthen the mechanical strength between the sidewall of ball seat and base plate further, it is preferable that the bottom panel side 5 of ball seat is the curved surface of indent.So make between base plate and sidewall, to be formed with a curved surface, then enter in ball pin and the process holding chamber can be decomposed the ball pin impulsive force for base plate effectively, and then improve the service life of ball seat.
Present invention also offers a kind of automobile ball pin control arm, this automobile ball pin control arm includes the arm body that is sequentially connected with and above-mentioned ball seat.
The preferred embodiment of the present invention is described in detail above in association with accompanying drawing; but; the present invention is not limited to the detail in above-mentioned embodiment; in the technology concept of the present invention; technical scheme can being carried out multiple simple variant, these simple variant belong to protection scope of the present invention.
It is further to note that, each concrete technical characteristic described in above-mentioned detailed description of the invention, in reconcilable situation, it is possible to be combined by any suitable mode, in order to avoid unnecessary repetition, various possible compound modes are no longer illustrated by the present invention separately.
Additionally, can also carry out combination in any between the various different embodiment of the present invention, as long as it is without prejudice to the thought of the present invention, it should be considered as content disclosed in this invention equally.
