Description

Technical Field

[0001] This application relates to flanged fork structures, and more particularly to a flanged fork, a transmission system, and a vehicle. Background Technology

[0002] In existing vehicle transmission systems, to ensure smooth assembly with associated flanges, the flange fork design requires ample space for its fitment. This necessitates a larger flange fork structure, increasing the overall weight of the transmission system and contradicting the automotive industry's trend towards lightweight and high-efficiency designs. Furthermore, assembling the existing flange fork with the gearbox using bolts requires wrenches to hold and secure the bolts while installing nuts and other components, making the assembly process complex and cumbersome. Additionally, after prolonged use, the bolts are prone to loosening due to rotation. Utility Model Content

[0003] In view of this, the purpose of this application is to provide a flange fork, a transmission system and a vehicle to solve the problems that existing flange forks increase the total weight of the transmission system and that the existing flange fork assembly process is more cumbersome and the bolts are prone to loosening after long-term use.

[0004] In accordance with the above objectives, a first aspect of the present invention provides a flange fork having a main body, wherein the main body includes a base plate portion and a flange portion connected sequentially; the main body further includes a limiting portion located at a first end in the axial direction of the base plate portion, the limiting portion being disposed around the flange portion, and the surface of the limiting portion having a knurled structure; the base plate portion further includes a first connecting portion, wherein when a first connecting member is correspondingly connected to the first connecting portion, the first connecting member abuts against the limiting portion; The main body also has a through hole that penetrates the substrate portion and the flange portion.

[0005] Preferably, the substrate portion is formed into a cylindrical structure, and the flange portion is located at the center of the end face of the first end of the substrate portion.

[0006] Preferably, the axis of the through hole is collinear with the axis of the substrate portion; the diameter of the through hole is 60mm~70mm.

[0007] Preferably, the limiting portion is formed into a circular ring structure.

[0008] Preferably, the outer diameter of the limiting part is 110mm~120mm.

[0009] Preferably, the distance between the top end of the limiting portion and the end face of the first end of the substrate portion is 4mm to 8mm.

[0010] Preferably, the first connecting portion includes a plurality of threaded holes, which are spaced apart around the limiting portion.

[0011] Preferably, the flange portion includes a first flange portion and a second flange portion, wherein the first flange portion and the second flange portion are formed into a V-shaped structure.

[0012] According to a second aspect of the present invention, a transmission system is provided, wherein the transmission system includes the flange fork as described above.

[0013] According to a third aspect of the present invention, a vehicle is provided, wherein the vehicle includes the transmission system described above.

[0014] According to the present invention, the flange fork, transmission system, and vehicle have a main body comprising a base plate portion and a flange portion connected sequentially, and a limiting portion located at a first end in the axial direction of the base plate portion. The limiting portion surrounds the flange portion and has a knurled structure on its surface. Thus, when the first connecting member is connected to the first connecting portion, the first connecting portion can abut against the limiting portion. The limiting portion with the knurled structure can effectively reduce the possibility of rotation of the first connecting member, thereby reducing the probability of the first connecting member becoming loose. In addition, the limiting portion can provide support for the first connecting member, that is, there is no need to use a wrench to fix the bolts, which effectively reduces the complexity of the assembly process. In addition, the main body is formed with a through hole that penetrates the substrate portion and the flange portion. The through hole can effectively reduce the weight of the main body, thereby reducing the total weight of the transmission system.

Rather, the examples described herein have been provided merely to illustrate some of the many feasible ways of implementing the methods, apparatus, and / or systems described herein that will be apparent upon understanding the disclosure of this application.

[0021] Throughout the specification, when an element (such as a layer, region, or substrate portion) is described as being "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, it may be directly "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, or there may be one or more other elements in between. In contrast, when an element is described as being "directly on" another element, "directly connected to" another element, "directly bonded to" another element, "directly on" another element, or "directly covering" another element, there may be no other elements in between.

[0022] As used herein, the term “and / or” includes any one of the relevant items listed and any combination of any two or more items.

[0023] Although terms such as “first,” “second,” and “third” may be used herein to describe individual components, assemblies, regions, layers, or parts, these components, assemblies, regions, layers, or parts are not limited by these terms. Rather, these terms are used only to distinguish one component, assembly, region, layer, or part from another. Therefore, without departing from the teachings of the examples described herein, the first component, assembly, region, layer, or part referred to as the second component, assembly, region, layer, or part may also be referred to as the second component, assembly, region, layer, or part.

[0024] For ease of description, spatial relation terms such as “above,” “upper,” “below,” and “lower” are used herein to describe the relationship between one element and another, as shown in the accompanying drawings.

[0028] According to a first aspect of this utility model, a flange fork is provided, such as... Figure 1 As shown, the flange fork in this embodiment has a main body, which specifically includes a base plate portion 1 and a flange portion 2 connected in sequence. Furthermore, the main body also includes a limiting portion 3 located at a first end in the axial direction of the base plate portion 1. The specific structure of the aforementioned portions of the flange fork according to this invention will be described in detail below.

[0029] In this embodiment, as Figure 1As shown, the substrate portion 1 is formed into a cylindrical structure, and a flange portion 2 is provided at the center of the end face of the first end in the axial direction. The structure of the flange portion 2 itself (for example, it includes a first flange portion and a second flange portion, and the first flange portion and the second flange portion are formed into a V-shaped structure) belongs to the conventional structure of existing flange forks. Therefore, the specific structure of the flange portion 2 and its connection method with the substrate portion 1 will not be described in detail.

[0030] Furthermore, a limiting portion 3 is formed at the first end of the substrate portion 1 in the axial direction. This limiting portion 3 is formed in a ring shape and surrounds the flange portion 2. The first connecting portion 11 includes a plurality of threaded holes, which are spaced apart around the limiting portion 3. Thus, when the first connecting member 5 (i.e., the stud) is connected to the first connecting portion 11, the first connecting member 5 abuts against the top end of the limiting portion 3. In this way, the limiting portion 3 can provide support for the first connecting member 5, eliminating the need to use a wrench to fix the bolt, effectively reducing the complexity of the assembly process. Preferably, the outer diameter of the limiting portion 3 is 110mm to 120mm, and the distance between the top end of the limiting portion 3 and the end face of the first end of the substrate portion 1 is 4mm to 8mm. This range is a preferred range that achieves the following technical effects of the limiting portion 3 after multiple experiments.

[0031] Furthermore, the surface of the limiting part 3 is formed with a knurled structure. The specific shape and specifications of the knurled structure are not limited. For example, the knurled structure can be formed as a grid. This can increase the friction between the first connecting member 5 and the limiting part 3, thereby effectively reducing the possibility of the first connecting member 5 rotating, and thus reducing the probability of the first connecting member 5 becoming loose.

[0032] In this embodiment, as Figure 1 As shown, the main body also has a through hole 4 penetrating the base plate portion 1 and the flange portion 2. Preferably, the axis of the through hole 4 is collinear with the axis of the base plate portion 1, and the diameter of the through hole 4 is 60mm~70mm. This through hole 4 allows for effective weight reduction of the main body while ensuring the basic function of the flange fork.

[0033] According to the flange fork of this utility model, the main body includes a base plate portion 1 and a flange portion 2 connected in sequence, and also includes a limiting portion 3 located at the first end in the axial direction of the base plate portion 1. The limiting portion 3 is arranged around the flange portion 2 and the surface of the limiting portion 3 is formed with a knurled structure. Thus, when the first connecting member 5 is connected to the first connecting portion 11, the first connecting portion 11 can abut against the limiting portion 3. The limiting portion 3 with the knurled structure can effectively reduce the possibility of rotation of the first connecting member 5, thereby reducing the probability of the first connecting member 5 becoming loose. In addition, the limiting portion 3 can provide support for the first connecting member 5, that is, there is no need to use a wrench to fix the bolts, which effectively reduces the complexity of the assembly process. Furthermore, the main body also has a through hole 4 that penetrates the base plate portion 1 and the flange portion 2. The setting of the through hole 4 can effectively reduce the weight of the main body, thereby reducing the total weight of the transmission system.

[0034] According to a second aspect of the present invention, a transmission system is provided, the transmission system comprising the flange fork described above.

[0035] According to a third aspect of the present invention, a vehicle is provided, the vehicle including the transmission system described above.

[0036] Finally, it should be noted that the above-described embodiments are merely specific implementations of this application, used to illustrate the technical solutions of this application, and not to limit them. The protection scope of this application is not limited thereto. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any person skilled in the art can still modify or easily conceive of changes to the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features, within the technical scope disclosed in this application.
