Description

Technical Field

[0001] The utility model relates to the technical field of automobiles, in particular to a modular X-shaped thrust rod for automobiles. Background Art

[0002] Through domestic search, it was found that the following patents have similarities with this utility model:

[0003] The invention with application number 201310250451.6 and title “An X-type thrust rod, rear suspension assembly and vehicle” discloses an X-type thrust rod, rear suspension assembly and vehicle. The X-type thrust rod comprises: a first V-shaped rod, which comprises a first rod and a second rod, the first rod and the second rod are connected to each other in a V shape at a first connection portion, and are symmetrical relative to the axis of symmetry; and a second V-shaped rod, which comprises a third rod and a fourth rod, the third rod and the fourth rod are connected to each other in a V shape at a second connection portion, and are symmetrical relative to the axis of symmetry, wherein the first connection portion and the second connection portion are connected to each other in a relatively rotatable manner. Thus, compared with the V-shaped thrust rod of the prior art, the X-type thrust rod of the present invention can have a smaller opening width at the same effective length and the same opening angle. Thus, it can adapt to a smaller installation space.

[0004] The V-shaped rod in this patent includes two rods connected to each other, which are connected to the axle 11 at the connection of the two rods, and are connected to the crossbeam of the frame 12 at the other ends of the two rods. At the connection between the V-shaped rod and the axle 11, the mounting surface is parallel to the axle. When the V-shaped thrust rod transmits a large lateral force, it is easy to cause the mounting bolts to be sheared off, and it is also easy to cause the elastic ball head between the rod head and the rod body to be damaged. In addition, in the special chassis for cranes, in order to ensure that the frame has sufficient rigidity, a box-type frame is usually used. However, the expansion angle of this V-shaped thrust rod is fixed, so that the overall width of the V-shaped thrust rod is fixed, so that the width of the recessed part for installing the thrust rod in the box-type frame is insufficient, making it difficult to install the V-shaped thrust rod and difficult to assemble. In small-tonnage cranes, the V-shaped thrust rod structure cannot even be used.

[0005] The utility model with application number 201320229045.7 and title “A thrust rod and vehicle” discloses a thrust rod and a vehicle. The thrust rod disclosed comprises at least four connecting rods (100), and also comprises a connecting seat (200), wherein the connecting seat (200) comprises a connecting seat body (210) and at least four connecting heads (220) fixed to the connecting seat body (210); the inner end of each connecting rod (100) cooperates with and is fixedly connected to one of the connecting heads (220); the connecting seat (200) can be formed by forging; the connecting rod (200) can be a tubular structure; the inner end of each connecting rod (100) can be sleeved on one of the connecting heads (220) and fixedly connected by cold welding. The thrust rod can be used to better limit the swing of the axle relative to the frame, thereby ensuring the comfort and safety of the vehicle; meanwhile, the thrust rod has a small volume and weight, which facilitates the arrangement and assembly of the axle and the frame.

[0006] Although the use of the above-mentioned thrust rod can improve the comfort and safety of the vehicle, the relative positions of the frame and the axle are also quite different due to the different specifications and models of the vehicles; and thus, corresponding thrust rods need to be provided to connect the frame and the axle. Since different thrust rods need to be provided for different vehicles, the cost of the vehicle is likely to increase. Therefore, how to reduce the increase in vehicle cost caused by the thrust rod is a technical problem that those skilled in the art need to solve. In view of this, the utility model provides a thrust rod, the components of which have strong versatility, and thus can provide a premise for reducing vehicle costs.

[0007] The utility model with application number 202020050821.7 and name "A combined X-type thrust rod multifunctional rectangular casting crossbeam" discloses a combined X-type thrust rod multifunctional rectangular casting crossbeam, which belongs to the field of automobile crossbeams. A combined X-type thrust rod multifunctional rectangular casting crossbeam includes a crossbeam body mainly composed of a first crossbeam part and a second crossbeam part, the first crossbeam part and the second crossbeam part are provided with matching first and second combination plates, the first and second combination plates are connected by locking bolts, and the locking bolts are threaded with locking nuts, the first and second crossbeam parts are provided with spatial double-angle X-push mounting seats on both sides, and the first and second crossbeam parts are provided with suspension beam connecting plates at their ends; the utility model reduces the number of assembled parts, simplifies the assembly process, reduces production costs, and reduces the weight of the chassis system assembly, so the energy consumption of the vehicle is relatively reduced, which improves the economic benefits of customers when using it.

[0008] The combined suspension in this patent has many parts, complex structure, low anti-roll capability of the system, single function of parts, low integration, high production price, poor market economy and competitiveness. Utility Model Content

[0022] The present invention will be further described below in conjunction with the embodiments and drawings: Embodiment 1

[0023] like Figure 1 and Figure 2 As shown, the X-type thrust rod includes a cover plate 1, a steel pipe 21 and a ball head 22. The steel pipe 21 is a hollow round tube, and the steel pipe 21 is bent. Both ends of the steel pipe 21 are provided with internal threads. One end of the ball head 22 is provided with a connecting rod, and the connecting rod is provided with external threads. The ball head 22 is connected to both ends of the steel pipe 21 by threaded connection through the connecting rod. The ball head 22 can also be installed to both ends of the steel pipe 21 by riveting or welding. Two bent steel pipes 21 are clamped between two cover plates 1, so that the cover plate 1, the steel pipe 21 and the ball head 22 form an X-shaped structure. The bent steel rod can adjust the bending angle according to the installation size of the specific vehicle model, so as to quickly meet the installation size requirements of various vehicle models. The cover plate 1, the steel pipe 21 and the ball head 22 form a modular X-shaped structure. Therefore, by changing the shape and / or size of the bent steel pipe 21 in the modular X-shaped structure, the modular X-shaped structure can be applied to various vehicle models. In addition, the bent steel pipe 21 can flexibly adjust the size of the pipe diameter, the bending position and the bending angle, and its strength is higher than that of the existing split thrust rod. The size and strength of the entire X-shaped thrust rod can be adjusted by adjusting the bending angle of the steel pipe 21 and the mounting groove 12, so that the X-shaped thrust rod can meet the installation size and strength requirements of various vehicle models.

[0024] The two cover plates 1 are both in the shape of a cuboid, and one side of the two cover plates 1 is provided with a mounting groove 12 matching the steel pipe 21, and the two steel pipes 21 are embedded in the mounting grooves 12 of the two cover plates 1; the other side of the two cover plates 1 is provided with a groove 11, and the positions of the groove 11 and the mounting groove 12 on the cover plates 1 are staggered. When the two bent steel pipes 21 are clamped between the two cover plates 1, since the side of the two cover plates 1 facing the steel pipe 21 is provided with a mounting groove 12 matching the shape of the steel pipe 21, the upper and lower sides of the two steel pipes 21 are embedded in the mounting groove 12 of the cover plates 1. When the shape and / or size of the steel pipe 21 is changed, the shape and / or size of the mounting groove 12 on the cover plate 1 is also changed accordingly, so that the shape and / or size of the mounting groove 12 on the cover plate 1 always matches the shape and / or size of the steel pipe 21, so that the modular X-shaped structure is stable and can prevent the steel pipe 21 and the cover plate 1 from moving or rotating relative to each other. The groove 11 of the cover plate 1 is also provided with a mounting hole 13 that passes through the cover plate 1. Bolts 3 are passed through the mounting holes 13 of the two cover plates 1 and tightened with nuts so that the two cover plates 1 clamp the two steel pipes 21 in the mounting groove 12. The two cover plates 1 are pressed together by the bolts 3 and the nuts, so that the two steel pipes 21 are clamped in the mounting groove 12, so that the structure of the X-shaped thrust rod is simple, the cost is low, and it can be quickly disassembled and assembled. Embodiment 2

[0025] like Figure 3 As shown, the difference between this embodiment and the first embodiment is that the bending position and the bending angle of the steel pipe 21 are different. In addition, after a steel pipe 21 is bent in the first embodiment, the shapes of the two ends of the steel pipe 21 are symmetrical, while after a steel pipe 21 is bent in the present embodiment, the shapes of the two ends of the steel pipe 21 are asymmetrical.

[0026] Obviously, without departing from the principle of the present invention, several improvements or modifications made should be regarded as within the protection scope of the present invention.
