Description

Technical Field

[0001] The invention relates to the field of automobile suspension accessories, and in particular to an automobile control arm with a reinforced protection structure. Background Art

[0002] The suspension system is a connection system between the wheels, the vehicle body and the vehicle frame, including elastic elements, guide mechanisms and shock absorbers, etc. The control arm is one of the guide mechanism elements. During the driving process of the car, due to the vibration caused by the change of the road surface and the need for steering, the wheels will inevitably jump up and down and swing left and right, and part of the force generated by the wheel movement will be transmitted to the vehicle body through the control arm. Therefore, the performance of the control arm will directly affect the safety, comfort and handling stability of the car, and must have a certain degree of rigidity and reliability. The control arm generally adopts a three-end connection method, with the ball head end connected to the car steering knuckle and the other two bushing ends connected to the body or subframe.

[0003] A Chinese patent discloses an automobile control arm (authorization announcement number CN 107471946 B). The patented technology ball head assembly is fixed on the control alarm body by clamping, which is convenient for the replacement of the ball head assembly. At the same time, it is convenient to lubricate the ball head regularly, with good lubrication effect, reducing the wear of the ball head, ensuring its performance and extending its service life. The ball head assembly has a good sealing effect, and the number of snap rings used when sealing the dust cover is reduced, thereby reducing the number of assembly parts and simplifying the assembly process. However, the ball head assembly is connected by two bolts. During installation, tools are required to tighten the bolts, and the installation method is relatively troublesome.

[0043] The working principle of the present invention is:

[0044] Before installing the ball head assembly;

[0045] The stopper 24 is pressed down, and the stopper 24 drives the moving block 22 to descend and compress the spring three 23, so that the right end of the limit sleeve 20 loses the limiting force. Then, the limit sleeve 20 is pushed to move to the right, and the limit sleeve 20 drives the slider 18 to move in the slide groove 17 and compress the spring two 19, so that the limit sleeve 20 leaves the two push plates 16, and the rotating plate 10 is pushed to reset by the reset thrust of the spring one 13. The rotating plate 10 drives the semicircular protrusion 11 on the right to extend out of the hidden groove, and the semicircular protrusion 11 on the left is placed in the hidden groove. The rotating plate 10 drives the push rod 15 to move outwards through the connecting rod 14, and the push rod 15 drives the push plate 16 to leave the through groove 9, and blocks the limit sleeve 20 through the push plate 16 to prevent the limit sleeve 20 from moving and resetting.

[0046] When you start installing the ball head assembly;

[0047] Insert the connecting block 27 into the connecting groove 8, and at the same time, insert the arc block 26 into the arc groove 7. When the connecting block 27 is inserted into the connecting groove 8, the semicircular protrusion 11 on the right is inserted into the clamping groove 28 on the right. The clamping groove 28 on the right will push the semicircular protrusion 11 on the right, so that the rotating plate 10 rotates around the rotating shaft 12. The spring 13 is compressed by the rotating plate 10. At the same time, the rotating plate 10 drives the semicircular protrusion 11 on the left to rotate out of the hidden groove and then insert it into the clamping groove 28 on the left. At the same time, the rotating plate 10 drives the push rod 15 to move through the connecting rod 14, and the push rod 15 drives the push rod 15 to move. The movable push plate 16 moves into the through slot 9. When the push plate 16 moves into the through slot 9, the limiting sleeve 20 loses its limiting force, the spring 2 19 resets and pushes the slider 18 to reset, and the slider 18 drives the limiting sleeve 20 to reset and sleeve outside the two push plates 16, giving the two push plates 16 a limiting force. At the same time, the limiting sleeve 20 resets and leaves the upper end of the stopper 24, and the spring 3 23 resets and pushes the moving block 22 and the stopper 24 to rise, and the stopper 24 rises to the right end of the limiting sleeve 20, giving the limiting sleeve 20 a limiting force, so that the ball head assembly is firmly installed on the side of the control arm 1, and the fixing effect is good;

[0048] When the ball head assembly is working;

[0049] The liquid storage chamber 30 is filled with lubricating oil, which is delivered to the plurality of liquid infusion holes 32. Since the roller 33 and the matching groove 31 are tightly fitted, the roller 33 blocks the lubricating oil, so that the lubricating oil cannot be discharged from the liquid infusion hole 32. However, the lubricating oil contacts the surface of the roller 33, and provides support force to the ball head 34 through the plurality of rollers 33.

[0050] When the ball head 34 is working and rotating, it will roll on the outer surface of the roller 33 in the spherical cavity 29. If there is no lubricating oil between the ball head 34 and the roller 33, the friction between the ball head 34 and the roller 33 will increase, which will cause the ball head 34 to drive the roller 33 to rotate. The roller 33 rotates with the rotation of the ball head 34, which can effectively reduce the wear of the ball head 34. At the same time, when the roller 33 rotates, the roller 33 rotates on the inner wall of the matching groove 31. The lubricating oil adheres to the surface of the roller 33 through the rotation of the roller 33, and then the roller 33 and the ball head 34 contact, and the lubricating oil is applied to the surface of the ball head 34, so that the lubricating oil adding work can be automatically completed. After the lubricating oil is added, the friction between the ball head 34 and the roller 33 is reduced, so that the roller 33 cannot rotate. When there is no lubricating oil on the surface of the ball head 34, the lubricating oil is applied to the ball head 34 through the roller 33.

[0051] When installing the dust-proof cone block 44;

[0052] Put a sealing ring 50 into the workpiece groove 49, then put the elastic mechanism into the workpiece groove 49, and then put the last sealing ring 50 into the workpiece groove 49, and then put the two rotating blocks 45 of the dustproof cone block 44 through the through groove 39 and the annular groove 38 into the annular cavity 37, rotate the dustproof cone block 44 clockwise, so that the two rotating blocks 45 rotate clockwise in the annular cavity 37, so that the rotating block 45 contacts and squeezes the first card block 42, so that the first card block 42 shrinks into the groove 40, and the spring four 43 is compressed. When the card groove 47 rotates to the position of the card block 42, the card block 42 loses its limiting force, and the spring four 43 The block 42 is pushed to reset and inserted into the slot 47 to fix the position of the rotating block 45, so that the dustproof cone block 44 is installed on the upper end of the fixing ring 36. The quarter-circle block setting of the block 42 makes it impossible for the dustproof cone block 44 to rotate counterclockwise, so that the dustproof cone block 44 can only be rotated clockwise through several blocks 42 before it can be pulled out and disassembled from the position of the through groove 39, effectively preventing the dustproof cone block 44 from being vibrated and falling off, and applying pressure to the two extrusion plates 51 through the spring 52, and applying pressure to the sealing ring 50 through the two extrusion plates 51, so that the sealing ring 50 is squeezed and deformed to fill the gap, thereby increasing the sealing effect.
