[0002] The stabilizer bar connecting rod is an important component in the automobile suspension system, which is used to connect the stabilizer bar and the suspension system, so as to transmit the torsional force of the stabilizer bar to the suspension system, thereby reducing the body roll of the vehicle when turning or driving on a bumpy road, and ultimately improving the stability and maneuverability of the vehicle.

[0003] In the design of the existing stabilizer bar connecting rod, it usually includes a rod body and a bushing and a ball head arranged thereon. At present, the bushing is generally arranged on the rod body by press fitting, and the ball head is rotatably connected to the ball head seat arranged on the rod body. After a period of use, the dust cover for preventing dust, water and other impurities needs to be removed as a whole, and then lubricating oil is added at the connection between the ball head and the ball head seat to ensure the flexibility of the ball head rotation.

[0004] However, the overall removal of the dust cover for the addition of lubricating oil is relatively cumbersome, and since the gap between the ball head and the ball head seat is relatively narrow (in order to ensure the stability of the ball head rotation), it is not conducive to the rapid lubrication of the friction surface of the ball head and the ball head seat by the lubricating oil, thereby reducing the flexibility of the ball head rotation. Moreover, the bushing is assembled by press fitting, and the bushing and the mounting hole may generate internal stress, which may cause fatigue cracks or failure after long-term use, i.e. the function of preventing rotation and falling off is lost. Therefore, a stabilizer bar connecting rod for automobile is proposed. UTILITY MODEL CONTENTS

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0028] Referring to Figures 1-6 The utility model provides a kind of technical scheme of automobile stabilizer bar connecting rod:

[0029] Referring to Figure 1 A kind of automobile stabilizer bar connecting rod, including shaft 1, the end of shaft 1 is provided with ball head 3 by ball head seat 4, dust cover 401, the inner bottom surface of ball head seat 4 is provided with bottom groove 7, the inner side surface of ball head seat 4 is evenly provided with several edge arc grooves 701, ball head 3 includes ball rod 301, ball body 302 and flange 303, ball body 302 is rotationally connected with the inner side surface of ball head seat 4, the lower end of dust cover 401 is fixed at the top edge of ball head seat 4 by first clamping spring 5, the upper end of dust cover 401 is clamped into the recess of groove by second clamping spring 501 by two flanges 303, the top surface of dust cover 401 is provided with notch 601, the inner bottom surface of notch 601 is provided with leakage hole 6, plug 602 is arranged in notch 601, the top surface of plug 602 is pressed tightly by second clamping spring 501.

[0030] It should be noted that there are two flanges 303 on the cue stick 301, as shown in the reference. Figure 2 As shown, the upper flange 303 is larger in size to prevent the ball head 3 from deflecting easily when rotating, while the lower flange 303 is smaller in size to reduce the friction when the ball head 3 rotates. The two flanges 303 form a groove in which the upper end of the dust cover 401 is inserted.

[0031] It should be noted that the sphere 302 is located at the end of the ball head 3, the bottom end of the sphere 302 is set as a flat cut surface 304, and the side arc groove 701 extends from the top of the inner side of the ball head seat 4 to the bottom groove 7 located on the inner bottom surface of the ball head seat 4. The side arc groove 701 is set at equal intervals around the bottom groove 7.

[0032] The flat surface 304 allows it to form a large gap with the bottom groove 7 for storing lubricating oil, thus reducing the frequency of adding lubricating oil to the device and making it easier to use.

[0033] By setting and cooperating with the vent 6, the notch 601 and the plug 602, the second snap ring 501 is fixed to the top of the dust cover 401 while pressing the plug 602, which facilitates the addition of lubricating oil when the ball head 3 rotates. The structure is simple and easy to operate, and it is suitable for widespread application.

[0034] By using the bottom groove 7 and the side arc groove 701, the lubricating oil stored in the bottom groove 7 can flow through the side arc groove 701 to the inner wall of the ball head seat 4 where the ball 302 is attached, so that the outer surface of the ball 302 can be quickly soaked with lubricating oil, which is beneficial to the rotation of the ball head 3. The lubricating oil added from the drain 6 can quickly fall from the side arc groove 701 into the bottom groove 7, making the process of adding lubricating oil smoother, saving time, and making the operation convenient.

[0035] Furthermore, an aluminum bushing 2 is provided at the other end of the shaft 1 away from the ball head 3, and an anti-rotation structure is provided between the shaft 1 and the aluminum bushing 2.

[0036] Reference Figure 2 As shown, in an optional embodiment, the anti-rotation structure includes a groove 201 formed in the middle of the aluminum bushing 2, and an external toothed ring 202 is provided in the middle of the groove 201.

[0037] It should be noted that the shaft 1 is provided with a matching hole 102 corresponding to the groove 201 and an internal tooth ring 101 corresponding to the external tooth ring 202 at the aluminum bushing 2. It should be further noted that in the embodiment, the shaft 1 and the aluminum bushing 2 are combined by a plastic packaging process. Therefore, the matching hole 102 and the internal tooth ring 101 are naturally formed structures on the shaft 1 in the plastic packaging process. The plastic packaging process is a prior art and will not be described in detail here.

[0038] The anti-disengagement and anti-rotation structure is provided by the engagement of the groove 201 and the matching hole 102 to prevent the aluminum bushing 2 from disengaging, and by the engagement of the external tooth ring 202 and the internal tooth ring 101 to prevent the aluminum bushing 2 from rotating. The structure is simple and efficient, and is suitable for popularization and use.

[0039] In an optional embodiment, the material of the shaft 1 can be nylon material, specifically high-glass fiber reinforced nylon material. Because it has high strength and high rigidity, it can effectively reduce the body roll of the vehicle installed with the stable rod connecting rod, thereby improving the handling stability of the vehicle.

[0040] In an optional embodiment, the material of the ball head seat 4 can be polyoxymethylene material. Because polyoxymethylene material has good wear resistance, the wear resistance of the ball head seat 4 can be improved.

[0041] In an optional embodiment, the material of the aluminum bushing 2 can be aluminum. Because aluminum has good wear resistance and light weight, the overall wear resistance of the stable rod connecting rod can be improved, and the overall weight can be reduced, thereby improving the fuel efficiency of the vehicle.

[0042] In an optional embodiment, the material of the plug 602 can be rubber. Because rubber has elasticity, the plug 602 can be designed slightly larger than the recess 601 in actual use. The plug 602 is squeezed into the recess 601, which utilizes the elasticity of rubber to improve the sealing performance of the recess 601, avoids the entry of foreign matter such as dust and water into the ball head seat 4, and avoids pollution.

[0043] Working principle: when the contact surface of the ball 302 and the ball head seat 4 needs to be added with lubricating oil, only need to take off the second snap spring 501, the process is prior art, not too much repetition here, buckle out the plug 602, pour lubricating oil into the notch 601, the lubricating oil will drip into the ball head seat 4 along the leakage hole 6, and enter the gap between the bottom groove 7 and the flat surface 304 through the edge arc groove 701, and then the plug 602 is buckled and the second snap spring 501 is installed, so that the plug 602 is tightly fixed, the lubricating oil in the gap between the bottom groove 7 and the flat surface 304 of the stable rod connecting rod in the actual use process will flow into the edge arc groove 701, and in the process of rotating the ball 302, it is coated on the outer side wall of the ball 302, thereby playing the effect of lubricating the rotation of the ball head 3.

[0044] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
