Specific embodiment
For ease of it will be appreciated by those skilled in the art that making with reference to the accompanying drawings and embodiments to the utility model further detailed
Description.
A kind of automobile control arm disclosed in the utility model, it is as depicted in figs. 1 and 2, total including control arm body 1, bulb
Into 2, small bushing 3, Large lining 4, the first bolt 5, the second bolt 6.The control arm body 1 is arc-shaped bend structure, using casting
Type is caused, there is engraved structure in inside, and is provided with three reinforcing ribs, and reinforcing rib forms triangular structure, can reach loss of weight
Effect, while the setting of reinforcing rib can increase structural strength, meet the performance requirement of structural strength.The control arm body
There are three connecting pins for setting on 1：First connecting pin 11, second connection end 12, third connecting pin 13, wherein bulb assembly 2 are set
In the first connecting pin, small bushing 3 is arranged on second connection end 12, and Large lining 4 is arranged on third connecting pin 13.
First connecting pin, 11 side of the utility model is provided with boss structure, jagged in the middle part of boss, makes described the
One connecting pin 11 forms " C " font, and bolt hole is provided on boss, for installing the first bolt 5 and the second bolt 6.Pass through
The locking of one bolt 5 and the second bolt 6 can reduce gap width, and then make the cylindrical type mounting hole internal diameter of the first connecting pin 11
It reduces, realizes the clamping of the bulb assembly 2 mounted on the first connecting pin 11, can conveniently realize to ball in this way
The maintenance and replacement of head assembly, simultaneously because bulb 21 occurs mild wear and causes between being generated between ball-type cover 25 and bulb 21
During gap, gap can be eliminated by suitably increasing the coupling mechanism force of the first bolt 5 and the second bolt 6.
As shown in figure 3, the bulb assembly 2 includes ball seat 24, the ball-type cover 25 being arranged in ball seat 24, is located at the ball
Bulb 21 in type cover 25, is fastened on 25 bottom of ball seat 24 and ball-type cover at the dust cover 22 being arranged between ball seat 24 and bulb 21
The lower cover 26 in portion, the rubber stopper 27 being arranged in 26 central through hole of lower cover.
As shown in figure 4, the dust cover 22 is rubber material, there is good elastic property, 22 upper end endoporus of dust cover is small
Achieve the effect that when the upper end outer diameter of bulb 21, assembling a kind of pre-sealed, and 22 upper end endoporus of dust cover and bulb 21 connect
Tactile position is provided with wavy shaped configuration, forms Multi-level sealing structure, and 22 upper end of dust cover is fixedly clamped with snap ring 23
On bulb 21, the sealing effect of Multi-level sealing structure is further ensured.As shown in figure 5, the lower end of the dust cover 22 is set
It is equipped with the inside turnup structure of thickening, the upper end of ball seat 24 is provided with circular groove structure, and turnup structure is located at annular during assembling
In groove structure, the installation positioning of 22 lower end of dust cover is realized, and passes through first connecting pin 11 and is clamped, dust cover
22 lower end can be securely fixed in annular groove, effectively prevent the displacement that comes off of dust cover 22, under dust cover 22
This fixed form at end avoids having used other parts that are fixedly clamped, and reduces Assembly part quantity, simplifies assembly technology.
The dust cover 22 being combined using the above structure with fixed form has good sealing effect, can effectively prevent dust and water
Enter in ball seat 24, avoid the corrosion of bulb 21, reduce abrasion and operation it is not smooth, extend service life.The ball

With precision.
As shown in fig. 6, the ball-type cover 25 uses resin material, for placing bulb 21, bulb 21 and ball seat are avoided
24 be in direct contact, reduces the abrasion of bulb 21, lubrication groove 252 is provided on 25 inner wall of ball-type cover, lubrication groove 252 exists
It is distributed on 25 inner wall of ball-type cover in decussation, respectively along the warp direction and weft direction of 25 inner wall of ball-type cover, cross
The lubrication groove 252 of shape can store more lubricant greases, and bulb 21 is lubricated in 21 operational process of bulb and is also more filled
Divide and uniformly, 25 bottom of ball-type cover is provided with stepped hole 251, the channel as injection lubricant grease.The lower cover 26 passes through rotation
Riveter skills form turnup structure in 24 lower end of ball seat and realize compression and fix, while realize bulb 21, ball-type cover 25 and ball seat
24 assembling.
As shown in fig. 7, having gap between the ball-type cover 25 and lower cover 26, lubricant grease, lower cover 26 can be held
Bottom centre is provided with through-hole, be add lubricant grease channel, be sealed by the way that rubber stopper 27 is filled in through-hole, rubber stopper and
Through-hole is interference fit.27 longitudinal section of rubber stopper is " work " font, is divided into big end and small end, blind hole is provided at small end
271 and sharper top, can ensure that rubber stopper is smoothly filled in hole using this structure, and big end it is flat can ensure it is good
Leakproofness, the sundries such as dust and water can be effectively prevented and entered in ball seat 24.When 21 lack of lubrication of bulb needs to add profit
During lubricating oil fat, remove rubber stopper 27, lubricant grease injected by the hole at the middle part of lower cover 26, lubricant grease by stepped hole 25 along
The lubrication groove 252 of lubrication right-angled intersection flow to 21 surrounding of bulb and generates lubricant effect, and rubber is filled in again after the completion of lubrication
Plug 27, the adding procedure of entire lubricant grease is very simple and convenient.
Although the utility model combination above example is described, the utility model is not limited to above-mentioned reality
Example is applied, and is only defined by the appended claims, those of ordinary skill in the art can modify and change to it easily,
But both fall within the scope of the appended claims within the limits of the protection.
