The stabilizer bar is a common vehicle transfer equipment, and current stabilizer bar structure mainly includes: stabilizer bar assembly, connect bush and support on the stabilizer bar assembly. The structural rigidity of the existing transverse stabilizer bar is fixed, and the structural rigidity of the existing transverse stabilizer bar cannot be flexibly adjusted according to the specific vehicle adjustment work requirement. Therefore, according to the control and comfort requirements of the whole vehicle, transverse stabilizer bars with different specifications are required to be manufactured when the chassis of the vehicle is adjusted.
Therefore, when the transverse stabilizer bar is used for teaching the vehicle, the stabilizer bar assembly needs to be frequently replaced so as to be matched with different vehicle chassis or different vehicle parameters. Specifically, when the whole vehicle is currently regulated, different roll stiffness is provided for the suspension by replacing stabilizer bars with different bar diameters and matched stabilizer bar bushings. Changing stabilizer bar assemblies of different diameters requires a professional technician, takes time and labor, and is difficult to operate, while on the other hand, providing stabilizer bar adjustment members of different diameters and matched bushings requires the assistance of the professional, and has long manufacturing period and high cost.

Therefore, even though the transverse stabilizer bar assembly with the structure is convenient to assemble and disassemble, the transverse stabilizer bar assembly still has the problems of long time consumption and difficult operation in actual work.
In summary, in the prior art environment, the stabilizer bar is used as an important adjusting part for the steering performance of the whole vehicle, and the only adjusting method at present is as follows: through changing the stabilizer bars of different pole footpaths, through real car evaluation to finally release stabilizer bar pole footpath and matched bush rigidity.

Detailed Description
The technical solutions in the embodiments of the present invention are further clearly and completely described below with reference to the accompanying drawings and the embodiments. It is clear that the examples described are for the purpose of explaining the technical solution of the invention and are not meant to be exhaustive of all embodiments of the invention.
Examples of the embodiments are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements throughout or elements having like or similar functionality. The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.
Referring to fig. 1, the present invention discloses a stabilizer bar for vehicle adjustment, and an adjustable connecting rod for the stabilizer bar. As shown in fig. 1, the stabilizer bar mainly includes a stabilizer bar body 4, a stabilizer bar mounting bracket 3, a stabilizer bar mounting bush 2, and an adjustable connecting rod 1.
The stabilizer body 4 is a long rod-shaped member, as shown in fig. 1, the stabilizer body 4 is not a straight rod, but a long rod with straight middle part and two side ends extending outwards to form an arm-shaped structure. There is a concavely folded region between the middle portion and the two side outwardly extending end portions of the stabilizer bar body 4, and the stabilizer bar body 4 passes through the stabilizer bar mounting bracket 3, so that the stabilizer bar mounting bracket 3 is located in the concavely folded region of the stabilizer bar body 4. The stabilizer bar installing support 3 has two, is located the concave district of the left and right sides of stabilizer bar body 4 respectively. The stabilizer bar body 4 is divided into a middle part, a left side part and a right side part by the left and right stabilizer bar mounting brackets 3, and the three parts can be respectively called a straight arm, a left swing arm and a right swing arm.
As an embodiment of the present invention, a stabilizer bar mounting bush 2 is provided between each stabilizer bar mounting bracket 3 and the stabilizer bar body 4, the stabilizer bar mounting bush 2 serving to seal a gap between the stabilizer bar mounting brackets 3 and the stabilizer bar body 4 and protect the stabilizer bar body 4 from abrasion.
It will be appreciated by those skilled in the art that the stabilizer bar mounting brackets 3 shown in fig. 1 are two in number and are respectively mounted on the left and right sides of the stabilizer bar body 4, but this embodiment is only one of many examples of the present invention and is not a limitation of the present invention. In other embodiments of the present invention, the stabilizer bar mounting brackets 3 may be other numbers, and the number of concave areas corresponding to the stabilizer bar body 4 may be determined according to the number of stabilizer bar mounting brackets 3. For example, the stabilizer body 4 may have four concavely folded regions, one stabilizer bar mounting bracket 3 for each concavely folded region, such that one stabilizer bar body 4 has four stabilizer bar mounting brackets 3 … … thereon, and so on. The technical purpose of the invention can be realized by various changes and combinations, and the technical effect of the invention is achieved.
With continued reference to fig. 1, the two ends of the stabilizer bar body 4, that is, the end of the left swing arm and the end of the right swing arm are respectively connected with an adjustable connecting rod 1, the adjustable connecting rod 1 is fixed on the two ends of the stabilizer bar body 4 through a fixing piece, and the left and right adjustable connecting rods 1 are symmetrical in position and are mirror structures. As can be seen from fig. 1, the three parts of the stabilizer bar body 4, i.e. the straight arm, the left swing arm and the right swing arm, are substantially in the same plane, whereas the adjustable connecting rod 1 is not in the same plane as the stabilizer bar body 4.
When carrying out the vehicle timing, stabilizer bar body 4 is fixed to the vehicle through stabilizer bar installing support 3 to adjustable connecting rod 1 of stabilizer bar body 4 both sides can adapt to the needs of different vehicle timing directly through its length, the regulation of angle, with this frequent change of avoiding stabilizer bar body 4.
Fig. 2 to 7 show the overall structure of the adjustable connecting rod 1 and the structure of its individual constituent parts.
Referring to fig. 2-5, the main structure of the adjustable connecting rod 1 is an upper sliding mechanism 7-1 and a lower sliding mechanism 7-2. The upper slide mechanism 7-1 has a structure with a larger diameter at one end and a smaller diameter at the other end. The larger diameter end of the upper sliding mechanism 7-1 is provided with a first cavity 12 with a hollow inside, and the section of the first cavity 12 is non-circular. The other end of the upper sliding mechanism 7-1 with smaller diameter is a first neck 8 with a hollow inside, and the section of the first neck 8 is round.
The lower slider 7-2 is similar in structure and specific shape to the upper slider 7-1, so that the lower slider 7-2 also presents a structure with a larger diameter at one end and a smaller diameter at the other end. The larger end of the lower sliding mechanism 7-2 is provided with a second cavity 11 with a hollow inside, and the section of the second cavity 11 is non-circular. The other end of the lower sliding mechanism 7-2 with smaller diameter is a second neck 13 with a hollow inside, and the section of the second neck 13 is circular.
Although the specific structure and shape of the lower sliding mechanism 7-2 are similar to those of the upper sliding mechanism 7-1, in the lower sliding mechanism 7-2, the outer diameter of the second cavity 11 is smaller than the inner diameter of the first cavity 12, so that the lower sliding mechanism 7-2 can be nested into the first cavity 12 of the upper sliding mechanism 7-1 through the second cavity 11. The upper and lower sliders 7-1, 7-2 are connected to each other by their first and second cavities 12, 11, respectively, while the other end of the upper slider 7-1, i.e., the first neck 8, and the other end of the lower slider 7-2, i.e., the second neck 13, are remote from each other. In the construction shown in fig. 2 to 5, the upper and lower slips 7-1 and 7-2 take on a straight line after connection, which also makes the adjustable connection rod 1 substantially straight.
Those skilled in the art will appreciate that the upper and lower slide mechanisms 7-1, 7-2, the first and second cavities 12, 11, the first and second necks 8, 13 are provided for different references to similar components in the adjustable connecting rod 1, and are not limiting on the component structure itself. In the figures shown in fig. 2-5, the first cavity 12 of the upper glide mechanism 7-1 has an inner diameter greater than the outer diameter of the second cavity 11 of the lower glide mechanism 7-2, but those skilled in the art will appreciate that in other embodiments of the invention the relationship may be reversed (interchanged), i.e., the inner diameter of the second cavity 11 of the lower glide mechanism 7-2 may be greater than the outer diameter of the first cavity 12 of the upper glide mechanism 7-1. The technical purpose of the invention can be achieved by the structural arrangement, and the technical effect of the invention is achieved.
As can be seen from fig. 2 to 5, the cross sections of the first cavity 12 of the upper sliding mechanism 7-1 and the second cavity 11 of the lower sliding mechanism 7-2 are square, which not only enable the second cavity 11 to match each other when being nested into the first cavity 12, but also enable no coaxial deflection between the second cavity 11 and the first cavity 12 after the second cavity 11 is nested into the first cavity 12, i.e. prevent torsion and bending between the second cavity 11 and the first cavity 12 (or between the upper sliding mechanism 7-1 and the lower sliding mechanism 7-2).
It will be appreciated by those skilled in the art that such a configuration will not allow for coaxial deflection between the first and second cavities 12, 11 as long as the first and second cavities 12, 11 are non-circular in cross-section. Therefore, the cross sections of the first cavity 12 and the second cavity 11 are only one of the numerous embodiments of the present invention, and in other embodiments of the present invention, the cross sections of the first cavity 12 and the second cavity 11 may be non-circular, such as rectangular, oval, etc., so that the technical purpose of the present invention can be achieved, and the technical effects of the present invention can be achieved.
With continued reference to fig. 2-5, the first cavity 12 and the second cavity 11 are connected by a rubber member 10, and the rubber member 10 is disposed in the second cavity 11 and has a through hole at the center thereof. Correspondingly, the first cavity 12 is internally provided with a metal skeleton bar 9, and the metal skeleton bar 9 passes through the through hole, so that the first cavity 12 and the second cavity 11 are connected and the distance is adjustable.
As a preferred embodiment of the present invention, the rubber member 10 is an i-shaped member having an i-shaped cross section, and both side surfaces thereof are fixed to the inner wall of the second chamber 11. The central position of the rubber member 10 is provided with a circular through hole, and the diameter and the size of the metal frame rod 9 are matched with those of the circular through hole at the central position of the rubber member 10. The two ends of the metal frame rod 9 are connected to the inner wall of the first cavity 12, which passes through the circular through hole in the center of the rubber member 10, so that the first cavity 12 and the second cavity 11 are connected and fixed to each other. Because the rubber member 10 has elasticity, the distance between the first cavity 12 and the second cavity 11 can be finely adjusted, so that the distance between the upper sliding mechanism 7-1 and the lower sliding mechanism 7-2 can be adjusted.
As another preferred embodiment of the present invention, the hardness of the rubber member 10 is optional, that is, the adjustable rigidity of the adjustable connecting rod 1 is changed by adjusting the hardness of the rubber member 10 to change the distance between the upper sliding mechanism 7-1 and the lower sliding mechanism 7-2, that is, the adjustable rigidity of the adjustable connecting rod 1 is changed, and the rigidity adjustment of the assembly of the adjustable connecting rod 1 with the transverse stabilizer bar is realized during the whole vehicle adjustment.
Because the upper sliding mechanism 7-1 and the lower sliding mechanism 7-2 are not locked by welding and bolts, when the upper sliding mechanism 7-1 and the lower sliding mechanism 7-2 are subjected to external tensile force, the rubber piece 10 can deform to a certain extent, so that the upper sliding mechanism 7-1 and the lower sliding mechanism 7-2 are far away from each other, and the length of the adjustable connecting rod 1 can be slightly prolonged. On the contrary, when the upper sliding mechanism 7-1 and the lower sliding mechanism 7-2 are subjected to inward thrust, the rubber member 10 can be deformed to a certain extent, so that the upper sliding mechanism 7-1 and the lower sliding mechanism 7-2 are close to each other, and the length of the adjustable connecting rod 1 can be slightly shortened.
By elastic deformation of the rubber member 10, fine adjustment of the distance of the intermediate position of the adjustable connecting rod 1 can be achieved. On the other hand, since the rubber member 10 has a through hole in the center, a metal frame rod 9 is provided at the position of the through hole, and both ends of the metal frame rod 9 are fixed to the inner wall of the first cavity 12. By such a structure, when the upper slider 7-1 and the lower slider 7-2 are moved toward or away from each other, they can still be kept in the connected state without being separated or excessively compressed.
As further shown in fig. 2-5, the first neck 8 of the upper glide 7-1 is generally cylindrical in shape, and fig. 4 shows the surface of the first neck 8 with length graduations 14 along the length, with the end of the first neck 8 being provided with a lock nut 6. Similarly, the second neck portion 13, which is located symmetrically to the first neck portion 8, is also substantially cylindrical in shape, the surface of the second neck portion 13 is also provided with length graduation marks 14 in the longitudinal direction, and the end of the second neck portion 13 is also provided with a lock nut 6.
As shown in fig. 4, the first neck 8 is provided with a viewing slot at the location of the length scale mark 14, which extends in the direction of the length scale mark 14 and is in close proximity to the length scale mark 14. Similarly, the second neck 13 is likewise provided with a viewing slot at the location of the length graduation 14, and this viewing slot likewise extends in the direction of the length graduation 14 and is in close proximity to the length graduation 14.
As an embodiment of the present invention, the lock nut 6 is a hexagonal lock nut 6, but the present invention is not limited thereto.
With continued reference to fig. 2-5, the adjustable connecting rod 1 further comprises two ball pins 5 with threaded rods 5-1. Two ball pins 5 with threaded rods 5-1 are arranged in the first neck 8 and the second neck 13, respectively. The ball pin 5 is inserted into the first neck 8 or the second neck 13 through the threaded rod 5-1 and is locked by the lock nut 6, thereby enabling the ball pin 5 to be fixed in position at the first neck 8 and the second neck 13.
Fig. 6 shows a specific structure of the ball pin 5 with the threaded rod 5-1. As shown in fig. 6, the ball pin 5 has a protruding connecting portion 5-3. The end of the threaded rod 5-1 is fixed to the surface of the ball pin 5, and the directions of the threaded rod 5-1 are perpendicular to each other in the direction of the protruding connecting portion 5-3 of the ball pin 5.
With continued reference to fig. 6, the surface of the threaded rod 5-1 is threaded and the surface of the threaded rod 5-1 is also provided with a datum line 5-2. When the threaded rod 5-1 is inserted into the first neck 8 or the second neck 13, the reference line 5-2 is positioned just inside the observation groove on the surface of the first neck 8 (or the second neck 13). As the threaded rod 5-1 is continuously inserted into the first neck 8 (or the second neck 13), the reference line 5-2 is continuously extended forward in the direction of the length scale line 14, and the extended length thereof can be observed through the observation groove, so that the length of the threaded rod 5-1 extending into the first neck 8 (or the second neck 13) can be accurately read. When the length of the threaded rod 5-1 extending into the first neck 8 (or the second neck 13) reaches the target, the threaded rod 5-1 can be fixed with the first neck 8 (or the second neck 13) by locking the nut 6.
By means of the engagement of the ball pin 5 with the threaded rod 5-1 with the first neck 8 (or the second neck 13), the distance of the ball pin 5 relative to the first cavity 12 (or the second cavity 11) can be adjusted and this adjustment can be performed precisely. The adjustment of the distance of the ball pin 5 from the first cavity 12 (or the second cavity 11) means that the length of the adjustable connecting rod 1 can be adjusted.
Through the structure, the length of the adjustable connecting rod 1 can be adjusted at least in three positions:
the first position is the middle position of the adjustable connecting rod 1, namely, fine adjustment is carried out between the first cavity 12 and the second cavity 11 through elastic deformation of the rubber piece 10, and at the moment, the second cavity 11 and the second cavity 11 bear outward pulling force or inward pushing force.
The second position is that the distance between the first neck 8 and the ball pin 5 is adjustable, which adjustment is achieved by loosening and tightening of the lock nut 6, to the extent that the ball pin 5 protrudes into the first neck 8, the accuracy of which is determined by the minimum unit of the length graduation mark 14.
The third position is that the distance between the second neck 13 and the ball pin 5 is adjustable, which adjustment is achieved by loosening and tightening of the lock nut 6, to the extent that the ball pin 5 protrudes into the second neck 13, the accuracy of which is determined by the minimum unit of the length graduation mark 14.
When all the components of the adjustable connecting rod 1 are connected and installed with each other, the whole adjustable connecting rod 1 presents the structure shown in fig. 2, all the internal components of the adjustable connecting rod 1 are arranged in a straight line, and the two ends of the adjustable connecting rod 1 are provided with ball pins 5.
Referring back to fig. 1, the adjustable connecting rod 1 is fixed to the end of the stabilizer bar body 4. Specifically, the ball pin 5 at one end of the adjustable connecting rod 1 is fixed to the end of the stabilizer bar body 4 by a fixing member, and the ball pin 5 at the other end of the adjustable connecting rod 1 can be connected to a vehicle to be calibrated.
Referring to fig. 7, an angle scale line 6-1 is provided at the thread opening of the lock nut 6, the angle scale line 6-1 is arranged at the thread opening of the lock nut 6 in a circular ring shape, and the angle scale line 6-1 can be matched with the datum line 5-2 on the surface of the threaded rod 5-1. When the threaded rod 5-1 is inserted into the first neck 8 (or the second neck 13), not only the threaded rod 5-1 is inserted into the length-adjustable, but also the threaded rod 5-1 can be rotated in the first neck 8 (or the second neck 13), so that the ball pin 5 connected to the end of the threaded rod 5-1 can be rotated through an angle. In this way, the ball pin 5 can be adjusted not only with respect to the distance of the first cavity 12 (or the second cavity 11) but also with respect to the angle with respect to the first cavity 12 (or the second cavity 11).
For example, when the ball pin 5 is coupled into the first neck 8 (or the second neck 13) through the threaded rod 5-1, the reference line 5-2 is observed through the observation groove of the surface of the first neck 8 (or the second neck 13) to observe the length scale line 14, and the specific length of the penetration is determined according to the reading of the length scale line 14. At the same time, reference line 5-2 likewise corresponds to an angle (e.g., 0 degrees in this case) of angle graduation line 6-1. When the ball pin 5 needs to be rotated by a certain angle, the threaded rod 5-1 can be rotated in the first neck 8 (or the second neck 13), and the rotating angle of the ball pin 5 is determined by reading the angle scale line 6-1 (for example, 90 degrees at this time, which indicates that the ball pin 5 is rotated by 90 degrees).
Rotation of the threaded rod 5-1 brings about rotation of the ball pin 5, whereas rotation of the ball pin 5 means that the protruding connection 5-3 is rotated in the same direction.
Through the above structure, the direction of the adjustable connecting rod 1 can be adjusted at least in two positions:
the first position is the direction (angle) of the ball pin 5 of the first neck 8, which is adjustable by loosening and tightening the lock nut 6, to the extent that the ball pin 5 rotates relative to the first cavity 12, the accuracy of which is determined by the minimum unit of the angle graduation marks 6-1.
The second position is the direction (angle) of the ball pin 5 of the second neck 13 is adjustable, which is achieved by loosening and tightening the lock nut 6, to the extent that the ball pin 5 rotates relative to the second cavity 11, the accuracy of which is determined by the minimum unit of the angle graduation marks 6-1.
The technical effect of the invention is that the adjustable connecting rod 1 can be fixed at the end of the stabilizer bar by means of a fastener (e.g. a fastening nut) by means of a ball pin 5 at one end thereof. At this time, when the vehicle is adjusted according to different manipulability and comfort, the other ball pin 5 of the adjustable connecting rod 1 may be rotated first in the direction of arrow a shown in fig. 1. Meanwhile, the threaded rod 5-1 respectively connected with the adjustable connecting rod 1 and the ball pins 5 can stretch and retract in the direction of the arrow B shown in fig. 1.
As shown in fig. 1, the rotation in the direction of arrow a is that the angle of the ball pin 5 of the adjustable connecting rod 1 is adjustable relative to the end of the stabilizer bar, and the expansion and contraction in the direction of arrow B is that the length of the adjustable connecting rod 1 is adjustable relative to the end of the stabilizer bar. By adjusting in the direction of arrow a and in the direction of arrow B, the invention makes it possible to adjust the length of the adjustable connecting rod 1, the angle of the ball pin 5, with respect to the end of the stabilizer bar body 4.
In summary, the invention has the following beneficial effects:
1. when the transverse stabilizer bar is used for vehicle adjustment, the rigidity adjustment of the stabilizer bar can be realized by only replacing a special adjustable connecting rod, and a series of transverse stabilizer bars with different bar diameters or bushing adjustment pieces with different rigidities are not required to be prepared.
2. The adjustable connecting rods are arranged on the outer side of the suspension, only a single piece is needed to be replaced, and compared with the existing mode of replacing the transverse stabilizer bar assembly, the adjustable connecting rods are simpler and quicker, and the rest parts are not affected.
3. The middle of the adjustable connecting rod is provided with the connecting device with different rigidities, the connecting device is provided with the accurate length and angle dial, and the connecting device is matched with the special ball pins at the two ends, can be directly combined into the adjustable connecting rod with different lengths, rigidities and ball pin angles through simple operation on site, and can be used for adjusting the rolling performance of different vehicle types.
