Detailed Description
The technical solutions in the embodiments of the present invention are further clearly and completely described below with reference to the drawings and the embodiments. It is obvious that the described embodiments are used for explaining the technical solution of the present invention, and do not mean that all embodiments of the present invention have been exhaustively exhausted.
Examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
Referring to fig. 1, the present invention discloses a stabilizer bar for vehicle tuning 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 bar-shaped member, and as shown in fig. 1, the stabilizer body 4 is not a straight bar, but a long bar having a straight middle portion and two side end portions extending outward to form an arm-shaped structure. There is a concave folding area between the middle part of stabilizer bar body 4 and the end parts extending outward on both sides, and stabilizer bar body 4 passes through stabilizer bar mounting bracket 3, so that stabilizer bar mounting bracket 3 is located in the above-mentioned concave folding area of stabilizer bar body 4. Stabilizer bar installing support 3 has two, is located the concave folding region of the left and right sides of stabilizer bar body 4 respectively. Through the left and right stabilizer bar mounting brackets 3, the stabilizer bar body 4 is divided into a middle portion, a left side portion, and a right side portion, which may be referred to as a straight arm, a left swing arm, and a right swing arm, respectively.
As an embodiment of the present invention, a stabilizer bar mounting bushing 2 is provided between each stabilizer bar mounting bracket 3 and stabilizer bar body 4, stabilizer bar mounting bushing 2 is used to seal a gap between stabilizer bar mounting bracket 3 and stabilizer bar body 4 and protect stabilizer bar body 4 from abrasion.
It will be understood 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 have other numbers, and the number of the concave-folded regions corresponding to the stabilizer bar body 4 may be determined according to the number of the stabilizer bar mounting brackets 3. For example, the stabilizer bar body 4 may have four recessed areas, one for each stabilizer bar mounting bracket 3, such that one stabilizer bar body 4 has four stabilizer bar mounting brackets 3 … … thereon, and so on. The above variations and combinations can achieve the technical objects of the present invention and achieve the technical effects of the present invention.
Continuing to refer to fig. 1, two ends of stabilizer bar body 4, namely the end of the left swing arm and the end of the right swing arm are connected with adjustable connecting rod 1 respectively, adjustable connecting rod 1 is fixed on two ends of stabilizer bar body 4 through the mounting, and two adjustable connecting rods 1 are symmetrical in position and are of mirror image structure. 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, while the adjustable connecting rod 1 and the stabilizer bar body 4 are not in the same plane.
When carrying out vehicle alignment, stabilizer bar body 4 passes through stabilizer bar installing support 3 and fixes on the vehicle to the adjustable connecting rod 1 of stabilizer bar body 4 both sides can directly adapt to the needs of different vehicle alignments through the regulation of its length, angle, with this frequent change of avoiding stabilizer bar body 4.
Fig. 2-7 show the overall structure of the adjustable connecting rod 1 and the structure of its various component 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 sliding mechanism 7-1 has a structure with one end having a larger diameter and the other end having a smaller diameter. The end of the upper sliding mechanism 7-1 with the larger diameter is a first cavity 12 with a hollow interior, and the cross 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 part 8 with a hollow inner part, and the section of the first neck part 8 is circular.
The lower sliding mechanism 7-2 is similar to the upper sliding mechanism 7-1 in structure and specific shape, so that the lower sliding mechanism 7-2 also presents a structure with a larger diameter at one end and a smaller diameter at the other end. The end of the lower sliding mechanism 7-2 with the larger diameter is a second cavity 11 with a hollow inner part, 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 inner part, 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 sliding mechanisms 7-1 and 7-2 are connected to each other through their first and second cavities 12 and 11, respectively, and the other ends of the upper and lower sliding mechanisms 7-1 and 7-2, i.e., the first and second necks 8 and 13, are distant from each other. In the configuration shown in fig. 2 to 5, the upper and lower sliding mechanisms 7-1 and 7-2 assume a straight shape after being connected, which also gives the adjustable connecting rod 1 a substantially straight shape.
Those skilled in the art will appreciate that the upper sliding mechanism 7-1, the lower sliding mechanism 7-2, the first cavity 12, the second cavity 11, the first neck 8, and the second neck 13 are different names for similar components of the adjustable connecting rod 1, and are not intended to limit the structure of the components themselves. In the drawings shown in fig. 2-5, the inner diameter of the first cavity 12 of the upper sliding mechanism 7-1 is larger than the outer diameter of the second cavity 11 of the lower sliding mechanism 7-2, but those skilled in the art will understand that in other embodiments of the present invention, the relationship between the two may be reversed (interchanged), that is, the inner diameter of the second cavity 11 of the lower sliding mechanism 7-2 may be larger than the outer diameter of the first cavity 12 of the upper sliding mechanism 7-1. The technical purpose of the invention can be realized 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, so that not only can the second cavity 11 be matched with each other when the second cavity 11 is nested in the first cavity 12, but also after the second cavity 11 is nested in the first cavity 12, no coaxial deflection occurs between the second cavity 11 and the first cavity 12, i.e. 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) are prevented.
It will be understood by those skilled in the art that the first and second cavities 12, 11 are non-circular in cross-section, so that no coaxial deflection occurs between the first and second cavities 12, 11. Therefore, the cross sections of the first cavity 12 and the second cavity 11 are square, which is only one of many 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 also be non-circular, such as rectangular, oval, etc., which can achieve the technical purpose of the present invention and achieve the technical effect of the present invention.
With continued reference to fig. 2-5, the first chamber 12 and the second chamber 11 are connected by a rubber member 10, and the rubber member 10 is disposed in the second chamber 11 and has a through hole at the center thereof. Correspondingly, a metal framework rod 9 is arranged in the first cavity 12, and the metal framework rod 9 penetrates through the through hole, so that the first cavity 12 and the second cavity 11 are connected and the distance is adjustable.
In a preferred embodiment of the present invention, the rubber member 10 is a member having an i-shaped cross section, and both side surfaces thereof are fixed to the inner wall of the second chamber 11. The center of the rubber part 10 is provided with a circular through hole, and the diameter and the size of the metal skeleton rod 9 are matched with the circular through hole at the center of the rubber part 10. The both ends of the metal skeleton 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, thereby connecting and fixing the first cavity 12 and the second cavity 11 to each other. Due to the elasticity of the rubber member 10, 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 hardness of the rubber member 10 is adjusted to change the distance between the upper sliding mechanism 7-1 and the lower sliding mechanism 7-2, which can be finely adjusted, that is, the rigidity of the adjustable connecting rod 1 is changed, so that the rigidity adjustment of the transverse stabilizer bar and adjustable connecting rod 1 assembly is realized during the adjustment of the whole vehicle.
Because the upper sliding mechanism 7-1 and the lower sliding mechanism 7-2 are not welded or locked by bolts, when the upper sliding mechanism 7-1 and the lower sliding mechanism 7-2 are subjected to external pulling force, the rubber piece 10 can deform to a certain degree, 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 extended. Conversely, when the upper sliding mechanism 7-1 and the lower sliding mechanism 7-2 are pushed inwards, the rubber part 10 can also deform 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.
Through the elastic deformation of the rubber member 10, the distance of the middle position of the adjustable connecting rod 1 can be finely adjusted. On the other hand, the rubber member 10 has a through hole in the center, the metal frame rod 9 is disposed at the through hole, and two ends of the metal frame rod 9 are fixed to the inner wall of the first cavity 12. With this structure, when the upper sliding mechanism 7-1 and the lower sliding mechanism 7-2 move toward or away from each other, they can still be connected to each other without being separated or excessively compressed.
As further shown in fig. 2 to 5, the first neck portion 8 of the upper sliding mechanism 7-1 is substantially cylindrical in shape, and fig. 4 shows that the surface of the first neck portion 8 is provided with length scales 14 along the length direction, and the end of the first neck portion 8 is provided with the lock nut 6. Similarly, the second neck portion 13, which is located symmetrically to the first neck portion 8, is also substantially cylindrical, and the surface of the second neck portion 13 is also provided with length marks 14 along the length direction, and the end of the second neck portion 13 is also provided with the lock nut 6.
As shown in FIG. 4, the first neck portion 8 is formed 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 abuts against the length scale mark 14. Similarly, the second neck portion 13 is also slotted with a viewing slot at the location of the length scale 14, and the viewing slot also extends in the direction of the length scale 14 and abuts the length scale 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 portion 8 or the second neck portion 13 through the threaded rod 5-1 and locked by the lock nut 6, thereby enabling the ball pin 5 to be fixed in position in the first neck portion 8 and the second neck portion 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 direction of the threaded rod 5-1 is perpendicular to 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 reference 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 located just inside the viewing 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 continuously extends forward in the direction of the length scale 14 and the length of the extension thereof can be observed through the observation slot, 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 portion 8 (or the second neck portion 13) reaches a target, the threaded rod 5-1 can be fixed to the first neck portion 8 (or the second neck portion 13) by the lock nut 6.
By means of the cooperation of the ball pin 5 with the threaded rod 5-1 and 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 carried out accurately. 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.
As can be seen from the above 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 the first cavity 12 and the second cavity 11 are finely adjusted through the elastic deformation of the rubber part 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 where the distance between the first neck portion 8 and the ball pin 5 is adjustable by loosening and tightening the lock nut 6 to a precise extent to which the ball pin 5 extends into the first neck portion 8, the accuracy of which is determined by the minimum unit of length scale 14.
The third position is that the distance between the second neck 13 and the ball pin 5 is adjustable, which is achieved by loosening and tightening the lock nut 6, to the exact extent to which the ball pin 5 protrudes into the second neck 13, the accuracy of which is determined by the minimum unit of the length scale 14.
When all parts of the adjustable connecting rod 1 are connected and mounted with each other, the whole adjustable connecting rod 1 assumes the structure shown in fig. 2, all internal parts thereof are arranged substantially in a straight line, and both ends of the adjustable connecting rod 1 are ball pins 5.
Referring back to fig. 1, the adjustable connection rod 1 is fixed to the distal end of the stabilizer bar body 4. Specifically, the ball pin 5 of one end of the adjustable connecting rod 1 is fixed to the end of the stabilizer body 4 by a fixing member, and the ball pin 5 of the other end of the adjustable connecting rod 1 can be connected to a vehicle to be adjusted.
Referring to fig. 7, an angle scale mark 6-1 is arranged at the threaded opening of the locking nut 6, the angle scale mark 6-1 is annularly arranged at the threaded opening of the locking nut 6, and the angle scale mark 6-1 can be matched with a reference 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 is the threaded rod 5-1 inserted to be adjustable in length, but the threaded rod 5-1 is also rotated in the first neck 8 (or the second neck 13), so that the ball pin 5 attached to the end of the threaded rod 5-1 is also 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 portion 8 (or the second neck portion 13) by the threaded shaft 5-1, the reference line 5-2 is viewed through the viewing groove of the surface of the first neck portion 8 (or the second neck portion 13) to view the length scale 14, and the specific length of penetration is determined according to the reading of the length scale 14. At the same time, the reference line 5-2 also corresponds to an angle (e.g., 0 degrees in this case) of the angle scale 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 portion 8 (or the second neck portion 13), and the angle of rotation of the ball pin 5 (for example, 90 degrees in this case, indicating that the ball pin 5 is rotated by 90 degrees) is determined by the reading of the angle scale 6-1.
Rotation of the threaded rod 5-1 causes rotation of the ball pin 5, which means that the projecting connection 5-3 is facing in the same direction.
As can be seen from the above structure, the direction of the adjustable connecting rod 1 can be adjusted at least in two positions:
the first position is that the orientation (angle) of the ball pin 5 of the first neck 8 is adjustable by loosening and tightening of the lock nut 6 to the exact angle through which the ball pin 5 is turned relative to the first cavity 12, the accuracy of which is determined by the smallest unit of the angle scale 6-1.
The second position is an adjustable orientation (angle) of the ball pin 5 of the second neck 13, which is achieved by loosening and tightening of the lock nut 6, precisely to the angle through which the ball pin 5 is turned relative to the second cavity 11, the accuracy of which is determined by the smallest unit of the angle scale 6-1.
The technical result of the present invention is that the adjustable connecting rod 1 can be fixed to the end of the stabilizer bar by a fastening member (e.g., a fastening nut) using a ball pin 5 at one end thereof. At this time, when the vehicle is adjusted according to different maneuverability and comfort, the other ball pin 5 of the adjustable connecting rod 1 can rotate 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 pin 5 can be extended and retracted 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 to adjust the angle of the ball pin 5 of the adjustable connecting rod 1 relative to the distal end of the stabilizer bar, and the expansion in the direction of arrow B is to adjust the length of the adjustable connecting rod 1 relative to the distal end of the stabilizer bar. Through the adjustment in the directions of the arrow A and the arrow B, the invention can realize that the length of the adjustable connecting rod 1 and the angle of the ball pin 5 can be adjusted relative to the tail end of the stabilizer bar body 4.
In summary, the present invention has the following beneficial effects:
1. when the transverse stabilizer bar is used for vehicle adjustment, rigidity adjustment of the stabilizer bar can be realized only by replacing a special adjustable connecting rod, and a series of transverse stabilizer bars with different bar diameters or bushing adjusting pieces with different rigidity do not need to be prepared.
2. The adjustable connecting rod is arranged on the outer side of the suspension frame, only needs to be replaced by a single piece, is simpler and quicker than the conventional mode of replacing the transverse stabilizer bar assembly, and does not influence other parts.
3. The middle of the adjustable connecting rod is provided with the connecting device with different rigidities, and the device is provided with the accurate length and angle dial scale which is matched with the special ball pins at the two ends, so that the adjustable connecting rods with different lengths, rigidities and ball pin angles can be directly combined through simple operation on site, and can be used for debugging the roll performance of different vehicle types.
It should be understood by those skilled in the art that the above embodiments are only for illustrating the present invention and are not to be used as a limitation of the present invention, and that changes and modifications to the above described embodiments are within the scope of the claims of the present invention as long as they are within the spirit and scope of the present invention.
