Technical Field

[0001] This invention relates to the field of automotive suspension, specifically to a multi-purpose stabilizer bar connecting rod and stabilizer bar assembly. Background Technology

[0002] Modern cars mostly use lateral stabilizer bar devices to improve vehicle stability. Generally, the two ends of the lateral stabilizer bar are connected to the steering knuckle or shock absorber bracket through stabilizer bar connecting rods, so that when the vehicle rolls, it can generate a large roll angle stiffness to resist the vehicle roll and improve vehicle stability.

[0003] In some off-road vehicles, in order to reduce the impact of the stabilizer bar on the left and right wheels and maximize the travel of the left and right wheels to improve the vehicle's off-road performance, disconnectable stabilizer bars or variable stiffness stabilizer bars (electronic stabilizer bars) are often used.

[0004] Disconnectable stabilizer bars or variable stiffness stabilizer bars are generally electronically controlled stabilizer bars, which are more expensive and are usually only used in some ultra-high-end models. They are rarely used in ordinary models.

[0041] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and the description of the preferred embodiments.

[0042] A multi-purpose stabilizer bar connecting rod 1-3 includes a connecting shaft 1. One end of the connecting shaft 1 is connected to an upper ball joint seat 3, and the other end is connected to a lower ball joint seat 4. The connecting shaft 1 includes an upper shaft 11 and a lower shaft 12. The lower shaft 12 has a insertion groove 121 near the end of the upper shaft 11, and the upper shaft 11 is inserted into the insertion groove 121 at the end of the lower shaft 12. This invention discloses a multi-purpose stabilizer bar connecting rod 1-3. By designing the stabilizer bar connecting rod 1-3 as a two-section structure, this invention allows for adjustment of the connecting rod's length as needed during actual use, thus giving the stabilizer bar connecting rod 1-3 a wider range of applications.

[0043] Specifically, the stabilizer bar connecting rod 1-3 disclosed in this invention mainly includes a connecting shaft 1. The connecting shaft 1 facilitates the bridging between the subsequent stabilizer bar 1-2 and the shock absorber 1-4, and plays a role in controlling vehicle roll and improving vehicle stability during subsequent use. In addition, the upper ball joint seat 3 and the lower ball joint seat 4 facilitate the connection between the stabilizer bar connecting rod 1-3 and adjacent components. At the same time, the connecting shaft 1 is divided into an upper shaft 11 and a lower shaft 12, and the upper shaft 11 can move within the insertion groove 121 in the lower shaft 12. Based on this configuration, the length of the connecting rod itself can be adjusted as needed during actual use, so that this invention can be used with shock absorbers 1-4 of different strokes.

[0044] Meanwhile, in this invention, the upper shaft 11 and the lower shaft 12 are connected by a fixing mechanism 2; the fixing mechanism 2 can realize the mutual positioning connection between the upper shaft 11 and the lower shaft 12, ensuring the stability of the connection between the upper shaft 11 and the lower shaft 12.

[0045] Furthermore, the fixing mechanism 2 in this invention includes a bolt connection portion. The bolt connection portion provides excellent binding and fixing, facilitating the relative locking and fixing of the upper shaft 11 and the lower shaft 12. Specifically, the bolt connection portion includes a locking bolt 22 on the lower shaft 12 and a connecting hole 122 on the lower shaft 12. The locking bolt 22 passes through the corresponding connecting hole 122 and abuts against the outer surface of the upper shaft 11 inside the lower shaft 12. The locking bolt 22 abuts against the upper shaft 11 at its end, providing excellent pressure and fixing, ensuring the stability of the upper shaft 11 within the insertion groove 121.

[0046] Furthermore, in this invention, a locking nut 21 is provided at the edge of the connecting hole 122; the locking bolt 22 passes through the locking nut 21; the basic function of the locking nut 21 is to act as a connector to facilitate the connection between the locking bolt 22 and the lower shaft 12, and another function is to increase the connection area between the lower shaft 12 and the locking bolt 22, so as to better ensure the stability of the connection of the locking bolt 22 to the lower shaft 12.

[0047] Furthermore, in this invention, multiple bolt connection parts are provided on the lower shaft 12, and the multiple bolt connection parts are symmetrically distributed on the lower shaft 12. Through this arrangement, this invention can ensure that the forces on the side of the upper shaft 11 are symmetrical, and avoid the upper shaft 11 from deflecting due to the pressure of the locking bolt 22.

[0048] Furthermore, in this invention, the upper shaft 11 and the lower shaft 12 are connected by a sliding part. The sliding part includes a slider 123 disposed on the inner wall of the insertion groove 121 and a sliding groove 111 disposed on the upper shaft 11. The slider 123 is engaged in the sliding groove 111. By setting the sliding part, this invention can ensure the mutual limiting of the upper shaft 11 and the lower shaft 12, and ensure the linearity of the relative movement of the upper shaft 11 and the lower shaft 12. At the same time, the cooperation between the sliding groove 111 and the slider 123 plays a good limiting role, preventing the upper shaft 11 and the lower shaft 12 from rotating relative to each other, thus affecting the stable use of the connecting rod.

[0049] Furthermore, in this invention, the upper ball pin seat 3 and the upper shaft 11, as well as the lower ball pin seat 4 and the lower shaft 12, are connected by an adjustment part. The adjustment part includes a screw 5 disposed on the upper ball pin seat 3 or the lower ball pin seat 4; a connecting blind hole 7 is provided at the end of the upper shaft 11 or the lower shaft 12; the upper ball pin seat 3 is connected to the connecting blind hole 7 of the upper shaft 11 by the screw 5; the lower ball pin seat 4 is connected to the connecting blind hole 7 of the lower shaft 12 by the screw 5. With the setting of the adjustment part, the orientation of the upper ball pin seat 3 or the lower ball pin seat 4 can be adjusted as needed during subsequent use, thereby enabling better use in practice.

[0050] In addition to being able to adjust the direction as mentioned above, it also has the function of increasing the length of the stabilizer bar connecting rod, which further expands the applicability of the invention.

[0051] In addition, in this invention, the connecting blind hole 7 and the screw 5 are connected by threads. Furthermore, in order to better ensure the stability of the connecting screw 5 in the connecting blind hole 7, this invention requires that a ball pin seat locking nut 6 be provided at the connection between the connecting screw 5 and the connecting blind hole 7.

[0052] Furthermore, in this invention, the stabilizing rod connecting rod 1-3 also includes a protective mechanism, which includes a sealing cover 4 sleeved at the insertion point of the upper shaft 11 and the lower shaft 12; the sealing cover 4 includes a cover body, the cover body is provided with a sleeve hole 403, and the cover body is sleeved at the insertion point of the upper shaft 11 and the lower shaft 12; specifically, in this invention, the sealing cover is equivalent to an outer cover structure, which covers the insertion point of the upper shaft and the lower shaft, and plays a good role in isolation and protection; specifically, in this invention, the sealing cover 4 plays a good role in protection and isolation, reducing or preventing external debris from entering the insertion groove 121.

[0053] Furthermore, in this invention, the cover includes a first cover 401 and a second cover 402. The first cover 401 is sleeved on the end of the lower shaft 12; the second cover 402 has a frustum-shaped structure; the sleeve hole 403 includes a first sleeve hole 4032 provided on the first cover 401 and a second sleeve hole 4031 provided on the second cover 402; the first cover 401 is used to connect with the lower shaft 12, and the second cover 402 is used to connect with the upper shaft 11. Meanwhile, in this invention, the first cover 401 is a frustum-shaped structure. The platform structure, with this design, creates a sloping surface on the outer side of the first cover. This design facilitates the scraping and cleaning of debris from the upper shaft 11, reducing or preventing debris from entering the insertion groove 121. Simultaneously, the aforementioned socket 403 includes a first socket 4032 on the first cover 401 and a second socket 4031 on the second cover 402. The arrangement of the first socket 4032 and the second socket 4031 facilitates the connection and assembly of the cover on the upper and lower shafts.

[0054] In addition, in this invention, the inner diameter of the first socket 4032 is larger than the inner diameter of the second socket 4031. Based on this setting, a stepped platform is formed inside the first cover and the second cover. This setting facilitates docking with the lower shaft during installation and thus plays a good role in limiting and positioning. At the same time, the triangular lip is made of rubber material, so that a sealing ring is formed around the platform, which better ensures the sealing of the cover.

[0055] Furthermore, in this invention, the second socket 4031 is provided with a plurality of triangular lips 4021; each triangular lip 4021 corresponds to a sliding groove 111; the plurality of triangular lips 4021 are symmetrically distributed in a ring at intervals; in this invention, the triangular lip 4021 is equivalent to a protrusion in the second socket 4031. In subsequent use, the triangular lip 4021 is engaged in the sliding groove 111. This arrangement plays a good role in sealing, isolating and blocking, which can not only prevent external debris from entering the insertion groove 121 through the sliding groove 111, but also scrape off the lubricating oil, preventing the lubricating oil from being exposed with the upper shaft 11 and causing pollution; in actual arrangement, each sliding groove 111 is required to correspond to a triangular lip.

[0056] Furthermore, in this invention, the triangular lip 4021 is provided with an avoidance notch 4022 at one end near the first socket 4032; the avoidance notch 4022 serves a storage function, providing storage space for scraped grease; better preventing grease from being squeezed out of the sealing cover 4; further improving the sealing performance of the sealing cover 4; and also increasing the deformation capacity of the triangular lip to a certain extent, reducing the excessive influence of the triangular lip on the relative movement of the upper and lower shafts.

[0057] A stabilizer bar assembly is provided, which is connected to a subframe 1-1. The stabilizer bar assembly includes a stabilizer bar 1-2 disposed on the subframe 1-1, and stabilizer bar connecting rods 1-3 are respectively connected to both ends of the stabilizer bar 1-2. Both ends of the stabilizer bar 1-2 are respectively connected to shock absorbers 1-4 through stabilizer bar connecting rods 1-3. Through this design, the stabilizer bar 1-2 and the shock absorber 1-4 have good linkage, thereby enabling the stabilizer bar 1-2 to control vehicle roll increase under non-off-road conditions, thus better ensuring the stability of vehicle operation.

[0058] specific:

[0059] This invention discloses a multi-purpose stabilizer bar connecting rod 1-3. The stabilizer bar connecting rod 1-3 mainly includes a connecting shaft 1. The connecting shaft 1 is designed with upper and lower sections, which can move relative to each other via a sliding groove 111 and a slider 123, or a ball bearing structure, thus achieving adjustable length. A sealing cover 4 with a triangular lip structure is provided at the joint of the upper shaft 11 and the lower shaft 12 to achieve sealing at the joint and improve the cleanliness of the joint section under harsh working conditions. Furthermore, in this invention, locking bolts 22 are evenly distributed on the outer shaft surfaces of the upper shaft 11 and the lower shaft 12, thereby enabling the stabilizer bar 1-2 to control vehicle roll and improve vehicle stability under non-off-road conditions. Simultaneously, to improve the platform application rate of the stabilizer bar connecting rod 1-3, the ball joint seat of the stabilizer bar connecting rod 1-3 is connected to the upper shaft 11 and the lower shaft 12 body via a threaded connection, thus enabling the ball joint seat of the stabilizer bar connecting rod 1-3 to be replaceable and its angle adjustable.

[0060] The advantages of this invention are:

[0061] The present invention has a simple structure and is easy to implement. Especially for off-road vehicles, when in off-road conditions, especially when crossing rough and bumpy roads, the use of this stabilizer bar connecting rod 1-3 helps to reduce the interference of the stabilizer bar 1-2 on the travel of the left and right shock absorbers, thereby increasing the wheel's contact with the ground, improving the wheel's adhesion, and improving the vehicle's passability.

[0062] specific;

[0063] In this invention, the car stabilizer bar connecting rod 1-3 is composed of an upper ball pin seat 3, a lower ball pin seat 4, a ball pin seat locking nut 6, an upper shaft 11, a lower shaft 12, a sealing cover 4, a sealing cover fixing clamp 41, several upper shaft 11 and lower shaft 12 locking bolts 22, and upper shaft 11 and lower shaft 12 locking nuts 21 (the number of which is the same as the number of locking bolts 22).

[0064] Among them, the screw 5 of the upper ball pin seat 3 is connected to the connecting blind hole 7 at the end of the upper shaft 11. After the upper ball pin seat 3 is connected to the upper shaft 11, it is locked by the ball pin seat locking nut 6. Similarly, the screw 5 of the lower ball pin seat 4 is connected to the connecting blind hole 7 at the end of the lower shaft 12. After the above connection, it is locked by the ball pin seat locking nut.

[0065] Meanwhile, in this invention, after the upper shaft 11 with the sliding groove 111 end is assembled with the upper shaft 11 and the lower shaft 12 sealing cover 4, it is fitted with the lower shaft 12 with the slider 123 end and inserted into the lower shaft 12. The upper shaft 11 and the lower shaft 12 sealing cover 4 are fitted into the lower shaft 12 and fixed with the sealing cover 4 fixing clamp. After the upper shaft 11 and the lower shaft 12 are adjusted to a suitable length, they are locked by the locking bolt 22 in the fixing mechanism 2 and prevented from loosening by the locking nut 21.

[0066] The present invention, through the above assembly method, can avoid assembly interference between the groove and the triangular lip inside the sealing cover.

[0067] In other words, by first assembling the upper shaft and the sealing cover in this invention, the accuracy of the assembly of the upper shaft and the sealing cover can be guaranteed.

[0068] The main reason for the advantages of the above assembly method is that when the sealing cover is connected to the lower shaft, the upper shaft needs to pass through the sealing cover before being inserted into the lower shaft. This requires the upper shaft to be inserted into the sealing cover first, and then into the lower shaft. Because the sealing cover has a triangular lip and the lower shaft has a slider at the end, the upper shaft needs to be precisely aligned twice to achieve the specific assembly operation. At the same time, when the upper shaft and the lower shaft are aligned and assembled, the lower shaft is in a blocked state because the sealing cover is already placed at the end of the lower shaft. The insertion of the upper shaft into the lower shaft is equivalent to blind insertion, which greatly increases the assembly difficulty.

[0069] When in off-road conditions, loosen the locking bolt 22 to allow relative movement between the upper shaft 11 and the lower shaft 12, thereby releasing the influence of the stabilizer bar 1-2 on the shock absorber stroke.

[0070] Furthermore, the range of vertical movement of the upper shaft 11 and the lower shaft 12 is greater than the shock absorber wheel travel, so as to avoid the upper shaft 11 and the lower shaft 12 falling off when jumping down or hitting the bottom when jumping up, which would affect the shock absorption travel.

[0071] The mating structure between the upper shaft 11 and the lower shaft 12, the groove 111 and the slider 123, can be triangular or rectangular, depending on the needs; of course, it can also be a ball bearing structure, etc.

[0072] The lower shaft 12 has threaded connecting holes 122, which are evenly arranged along the circumference according to the diameter of the lower shaft 12, and the number depends on the requirements.

[0073] Meanwhile, in this invention, lubricating grease is added to the moving space of the upper shaft 11 and the lower shaft 12 to reduce sliding friction. In order to improve the sealing performance at the mating point of the upper shaft 11 and the lower shaft 12, a sealing cover 4 is provided between the upper shaft 11 and the lower shaft 12.

[0074] The sealing cover is divided into upper and lower parts. The part that mates with the upper shaft 11 is conical, and the part that mates with the lower shaft 12 is cylindrical. Both parts are interference fits. The part that mates with the upper shaft 11 is conical on the outside and has a shape that mates with the upper shaft 11 on the inside. The spacing between the symmetrically arranged triangular lips 4021 is required to be smaller than the diameter of the upper shaft 11 groove 111 to ensure that it is an interference fit with the groove 111.

[0075] To ensure a good seal, the triangular lip 4021 is designed as a triangle, and three sealing rings are provided at the joint with the upper shaft 11.

[0076] Meanwhile, in this invention, the triangular lip 4021 is designed in the shape of a triangle. The main purpose of designing the lip in the shape of a triangle is that during the compression process between the upper shaft 11 and the lower shaft 12, the upper part of the lip will be in close contact with the upper shaft 11, thereby scraping off the dust and dirt on the exposed part of the upper shaft 11 through the sharp corner of the upper part of the triangle, and sliding off through the outer conical surface; during the stretching process between the upper shaft 11 and the lower shaft 12, the lower part of the lip will be in close contact with the upper shaft 11, thereby scraping off the grease on the upper shaft 11 through the sharp corner of the lower part of the triangle, and preventing it from being carried out.

[0077] To further improve sealing performance, a clearance notch 4022 is provided on the triangular lip 4021. The clearance notch 4022 is a triangular notch that provides space for scraped grease and prevents the grease from being squeezed out. The circumference diameter D1 of the outer edge of the triangular notch is smaller than the diameter D of the groove of the lower shaft 12, thus playing a good role in sealing and protection.

[0078] Furthermore, in this invention, the scale on the locking bolts 22 of the upper shaft 11 and the lower shaft 12 facilitates the adjustment of the length of the locking bolts 22 into the lower shaft 12 according to the diameter difference between the upper shaft 11 and the lower shaft 12 when locking the upper shaft 11 and the lower shaft 12, and keeps the screwing length of all locking bolts 22 consistent, thereby improving the coaxiality of the upper shaft 11 and the lower shaft 12 when used in off-road conditions; in addition, in order to improve the sealing performance of the locking nut 21 and the bolt, a sealing washer or sealing ring is provided at the mating part of the locking nut 21 and the lower shaft 12.

[0079] Both the upper shaft 11 and the lower shaft 12 have threaded blind holes 7 at their non-cooperating ends, which facilitates assembly with the threaded end of the screw 5 on the side of the ball pin seat. This design allows for adjustable ball pin seat angle and interchangeable ball pin seat size, and locking with ball pin seat locking nut 21. Combined with the adjustable and interchangeable lengths of the upper shaft 11 and the lower shaft 12, this stabilizer connecting rod 1-3 can be used on multiple platforms, improving the versatility.

[0080] The specific effects are as follows:

[0081] The above design allows for the full release of shock absorber travel in off-road conditions, improving off-road performance.

[0082] The adjustable and interchangeable upper shaft 11, lower shaft 12, ball pin assembly, etc. enable multi-platform compatibility and improve the generalization rate.

[0083] The triangular design of the lips of the upper shaft 11 and lower shaft 12 sealing cover 4 improves the sealing performance against dirt and grease.

[0084] Obviously, the specific implementation of this invention is not limited to the above-described methods. Any non-substantial improvements made using the inventive concept and technical solution of this invention are within the protection scope of this invention.
