Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.It is to be understood that
It is that detailed description of the invention described herein is merely to illustrate and explains this utility model, is not used to limit
This utility model processed.
In this utility model, in the case of illustrating on the contrary, the bag such as " top, the end, inside and outside "
The noun of locality being contained in term only represents this term orientation under normal service condition, or is this area skill
What art personnel understood is commonly called as, and is not construed as the restriction to this term.
This utility model provides the ball seat of a kind of automobile ball pin control arm, ball seat open top to recessed
Falling into and be formed with receiving chamber, be specifically shown in Fig. 3 and Fig. 4, the sidewall of this ball seat includes vertically the most successively
Section 1, neck section 2 and extension 3, vertical section 1 is positioned at the two ends of neck section 2 also with extension 3
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,
Make to put the distortion allowance at mouth by arranging inclined-plane 4 in the extension 3 (i.e. at ball seat pendulum mouth) of ball seat
Increase, and then the deformation basal area putting tensile strength and ball seat at mouth is increased, then can either expire
Foot increases the requirement of pivot angle, can improve again the pull-out force of ball pin, finally make the automobile ball pin control prepared
Arm processed and ball seat thereof are respectively provided with the safety of excellence and excellent service life.
In this utility model, the inclined degree on inclined-plane 4 can select in wide scope, although inclined-plane
The inclined degree of 4 is the most serious more can improve the tensile strength at pendulum mouth, but from the overall machinery of ball seat
Intensity considers, it is to avoid neck section 2 can be caused excessive pressure by the pulling force that inclined-plane 4 receives, it is preferable that
The acute angle formed between inclined-plane 4 and plane is 15-45 °.So, inclined-plane 4 can either improve at pendulum mouth
Tensile strength, enable to again neck section 2 and extension 3 cooperate to improve the entirety of ball seat
Mechanical strength.
In the present embodiment, inclined-plane 4 can select in the same manner as the area ratio of plane in wide scope,
But on the basis of meeting the tensile strength that inclined-plane 4 improves at pendulum mouth, make the extension 3 can simultaneously
The latching force of fastening is provided, it is preferable that inclined-plane 4 and the area ratio of plane for being positioned at the ball pin accommodating chamber
For 3-5:1.Thus, the face of the top of the section of will extend over 3 is set to plane and can be effectively improved again
The thickness of upper end and then raising mechanical strength herein such that it is able to extension 3 can firmly be locked
Slam-shot pin.
Additionally, be also can be about the aspect ratio between vertical section 1, neck section 2 and extension 3
Change in wide scope, is similarly the overall mechanical strength in order to improve ball seat, it is preferable that along
Vertical direction, the aspect ratio including 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, under this aspect ratio, ball seat
Sidewall can give the coupling mechanism force maximum with ball pin.
It addition, the concrete structure accommodating chamber can also select, as long as can put forward ball pin in wide scope
For stable coupling mechanism force and ball pin pull-out force just can, but in order to improve coupling mechanism force and the ball of ball seat further
Pin pull-out force, it is preferable that accommodate chamber and include what cylindrical cavity and aperture were the most upwards shunk the most successively
Revolution body cavity；Wherein, the axis of revolution body cavity and the dead in line of cylindrical cavity, and turn round the mother of body cavity
Line is the curve of evagination.So revolution body cavity at top can be by ball pin stably snap close in accommodating intracavity.
In the above-described embodiment, so that the structure accommodated between each several part of chamber is more stable, therefore
Need to coordinate by between the sidewall each several part of ball seat, it is preferable that cylindrical cavity is enclosed by vertical section 1
Forming, revolution body cavity is enclosed with extension 3 by neck section 2 and forms.The most just can be by the Bai Kouchu of ball seat
Tensile strength coordinate closely with the coupling mechanism force accommodating chamber, improve the overall machinery of ball seat with this
Intensity.
On the basis of the above, the machinery in order to strengthen further between the sidewall of ball seat and base plate is strong
Degree, it is preferable that the bottom panel side 5 of ball seat is the curved surface of indent.So make shape between base plate and sidewall
Cheng Youyi curved surface, then can effectively decompose ball pin the end of for during ball pin enters and accommodates chamber
The impulsive force of plate, and then improve the service life of ball seat.
This utility model additionally provides a kind of automobile ball pin control arm, and this automobile ball pin control arm includes successively
The arm body connected and above-mentioned ball seat.
Preferred implementation of the present utility model is described in detail above in association with accompanying drawing, but, this practicality is new
Type is not limited to the detail in above-mentioned embodiment, in technology concept of the present utility model,
The technical solution of the utility model can be carried out multiple simple variant, these simple variant belong to this reality
With novel protection domain.
It is further to note that each the concrete technology described in above-mentioned detailed description of the invention is special
Levy, in the case of reconcilable, can be combined by any suitable means, in order to avoid need not
The repetition wanted, various possible compound modes are illustrated by this utility model the most separately.
Additionally, combination in any can also be carried out between various different embodiment of the present utility model, only
