Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
FIG. 1 is a schematic block diagram of a bracket coupled to a subframe and a forearm according to one embodiment of the application. In this embodiment, the brackets 100 include two, and both brackets 100 are connected to the sub-frame 200. The two brackets 100 are disposed axisymmetrically opposite to each other, and each bracket 100 is connected to one of the toe-arms 300 at the outside (the left side of the left bracket 100 belongs to the outside, and the right side of the right bracket 100 belongs to the outside), respectively. And the forearm 300 may be rotated and translated when attached to the corresponding support 100.
Specifically, FIG. 2 is a schematic block diagram of a bracket according to one embodiment of the present application; fig. 3 is a schematic structural view of another angle of a bracket according to an embodiment of the present application. The present embodiment provides a bracket 100 for connecting a sub-frame 200 and a front arm 300 of a vehicle, and the bracket 100 may include a connection portion 10 and a mounting portion 20. Wherein the connection portion 10 is connected to the sub-frame 200 by a first fastener (not shown in the drawings, specifically, the first fastener may be a bolt, a screw, or the like). One end of the mounting portion 20 is connected to the connecting portion 10 and the other end is connected to the forearm 300, and the mounting portion 20 is configured such that the forearm 300 can rotate and translate when the forearm 300 and the mounting portion 20 are connected together.
The bracket 100 of the present embodiment includes only the connection portion 10 and the mounting portion 20, and is compact in structure, small in size, and light in weight, and can realize configuration switching under the condition of limited space structure.
In fact, since the bracket 100 of the prior art is fixed when connected to the forearm 300, the forearm 300 cannot be adjusted, resulting in limitation of the forearm 300 during actual use, and thus, the four-wheel positioning parameters can be ensured only with precision, increasing costs. When the bracket 100 in the embodiment is connected with the front beam arm 300, the front beam arm 300 can rotate and translate, so that the problem that four-wheel positioning parameters can only be ensured by precision is solved, the processing precision of relevant parts of the whole vehicle can be reduced, and further the processing and manufacturing cost is reduced.
As one embodiment of the present application, the mounting portion 20 is configured in a "U" shape in cross section, including support portions 21 disposed opposite to each other at a distance, and a bridging portion 22 connecting the two support portions 21, and the toe-in arm 300 is disposed between the two support portions 21 by the second fastener 30. The bridging portions 22 are connected to the connecting portion 10, and each of the supporting portions 21 extends from the bridging portion 22 in a direction opposite to the connecting portion 10. For example, in fig. 2, the support portion 21 extends leftward, while the connection portion 22 is at the right side.
Further, as an embodiment, each support portion 21 is plate-shaped and provided with a waist-shaped hole 23, the plate surfaces of the two support portions 21 are parallel to each other, and the two waist-shaped holes 23 are provided corresponding to each other to allow the same second fastener 30 to pass through, so that the toe-arm 300 is provided at the support portion 21, thereby enabling the toe-arm 300 to rotate about the second fastener 30 and the toe-arm 300 to translate along the waist-shaped hole 23 with the second fastener 30. In this embodiment, the center distance of each waist-shaped hole 23 is 10-15mm. For example, it may be 10mm, 12mm or 15mm. The travel of the toe-in arm 300 along with the translation of the second fastener 30 may be 10-15mm.
The cross section of the mounting portion 20 in this embodiment is "U" shaped, and may include a support portion 21 and a bridge portion 22, where the support portion 21 extends leftward such that the opening of the mounting portion 20 faces the left side in the drawing, and the plane of the two support portions 21 is substantially parallel to the surface of the subframe 200 adjacent to the support portion 21. A space is provided between the two support portions 21 to accommodate the toe-in arm 300, and the toe-in arm 300 is rotatable along a plane parallel to the plane of the support portions 21. The angle at which the forearm 300 is rotated is related to the position where the support 100 and the forearm 300 are located and the mounting positions of other surrounding components. And when the forearm 300 rotates, the rotation and the translation can be simultaneously performed due to the space limitation, so that the normal movement of the forearm 300 is ensured.
In addition, the support portions 21 have waist-shaped holes 23, and the second fasteners 30 pass through the waist-shaped holes 23 of the two support portions 21 and the front beam arms 300 to connect the mounting portions 20 and the front beam arms 300 together. In this embodiment, the second fastener 30 may be a bolt, and the toe-in arm 300 may rotate around the bolt because the bolt is circular. And since the bolt is disposed in the kidney-shaped hole 23, the bolt can also translate along the kidney-shaped hole 23. Accordingly, the toe-in arm 300 also translates along with the bolt in the direction of the waist-shaped hole 23. In fact, the prior art does not allow adjustment of the four-wheel alignment parameters or can only be adjusted with adjustment accuracy, increasing costs, since the forearm 300 cannot be adjusted during actual use of the forearm 300. The present embodiment can directly perform rotation and translation of the forearm 300 through the bracket 100, so that the four-wheel positioning parameter can be adjusted, and the cost is reduced while the performance of the vehicle is satisfied.
As a specific embodiment of the present application, each support portion 21 is provided with a groove 24 at the side facing the outside in this embodiment, and the waist-shaped hole 23 of each support portion 21 is provided at the position of the corresponding groove 24.
As shown in fig. 2 in particular, grooves 24 are provided on opposite sides of the two support portions 21, respectively, in such a manner that the gaskets of the bolts are located inside the grooves 24 to prevent the mounting positions of the bolts from being shifted. The gasket of the embodiment is an eccentric gasket, and the gasket can be fixed in the groove 24, but the translation of the bolt in the waist-shaped hole 23 is not affected.
As an embodiment of the present application, at least two through holes 11 are provided at the connection portion 10 in the present embodiment, each through hole 11 allowing a corresponding first fastener to pass therethrough to mount the connection portion 10 at the sub-frame 200. At least two through holes 11 can ensure a stable connection of the connection part 10 with the sub-frame 200.
Specifically, the central axes of the through holes 11 may be parallel or non-parallel. When the central axes between the through holes 11 are not parallel, it is indicated that the connection portion 10 may not be disposed on one plane, and thus the plurality of through holes 11 and the plurality of first fasteners are not disposed in parallel side by side, but may have various angles. It should be noted that the case where the central axes of the plurality of through holes 11 are not parallel may include a case where the central axes of some of the through holes 11 are parallel and the central axes of other part of the through holes 11 are not parallel to the central axes of some of the through holes 11, or may include a case where the central axes of all the through holes 11 are not parallel to each other. The angle between the central axes of the non-parallel vias may be in the range of 0-10 degrees (excluding 0 degrees). The angle of the specific through hole is related to the adaptive mounting surface, so that more mounting surfaces can be adapted, the adapted mounting surface is freely designed according to the space and stress requirements, and the whole structure can meet the performance and the assembly requirements.
As an embodiment of the present application, three through holes 11 are provided at the connection portion 10, and the line connecting the centers of the three through holes 11 is triangular. In this embodiment, three through holes 11 are arranged in a triangle, and are connected to the rear cross member of the subframe 200 by first fasteners passing through the through holes 11. The three-point connection in this manner can make the connection of the bracket 100 with the sub-frame 200 more stable.
Specifically, in the present embodiment, the connection portion 10 is of a "C" type structure, and the connection portion 10 is connected to the mounting portion 20 at a middle position of the "C" type structure. Two of the through holes 11 of the connection part 10 are located at both end positions of the "C" shaped structure of the connection part 10, and the other through hole 11 is located at the middle position of the "C" shaped structure. The connecting portion 10 is connected to the mounting portion 20 at a side of the through hole 11 at a middle position of the "C" structure. The plane formed in the middle of the connection portion 10 is at a predetermined angle to the plane in which one of the support portions 21 is located. Specifically, the opening of the "C" type structure of the connecting portion 10 in the present embodiment is directed to the right. In other embodiments, the structure of the connection may be other shapes that meet the performance.
In this embodiment, the preset angle may be 0-10 degrees. When the preset angle is 0 degrees, it is indicated that the plane in which the middle portion of the connection portion 10 is located and the plane in which the support portion 21 is located are parallel to each other. When the preset angle is greater than 0 degrees, it is indicated that the plane of the supporting portion 21 and the plane of the middle portion of the connecting portion 10 have a certain angle, and the angle can be freely adjusted according to the structure of the actual subframe 200 and the structure and mounting position of the actual forearm 300 or other components of the vehicle.
Specifically, the bracket 100 of the embodiment is integrally formed by casting the connecting portion 10 and the mounting portion 20, so that the forming process of the bracket 100 of the embodiment is simple, and the bracket can be completed only by casting and machining, thereby reducing the welding process and saving the cost.
As another embodiment of the present application, the present application also provides a vehicle, which may include a sub-frame 200, a front beam 300, and a bracket 100, wherein the bracket 100 is connected to the sub-frame 200 and the front beam 300, and the bracket 100 includes two brackets, which are disposed on the sub-frame 200 in an axisymmetric manner. The vehicle with the bracket 100 solves the problem that four-wheel positioning parameters can only be ensured by precision, so that the machining precision of relevant parts of the whole vehicle can be reduced, and the machining and manufacturing cost of the vehicle is further reduced.
By now it should be appreciated by those skilled in the art that while exemplary embodiments of the application have been shown and described in detail herein, many other variations or modifications that are consistent with the principles of the application may be directly ascertained or derived from the teachings of the present disclosure without departing from the spirit and scope of the application. Accordingly, the scope of the present application should be understood and deemed to cover all such other variations or modifications.
