Description

Technical Field

[0001] This utility model relates to the field of drive shaft technology, and in particular to a drive shaft assembly, powertrain, and vehicle. Background Technology

[0002] In existing technologies, drive shaft assemblies consisting of multiple drive shafts, especially those consisting of three drive shafts, require two supports to connect and constrain the two drive shafts, allowing the multiple drive shafts to be arranged according to the design. However, using two supports is relatively expensive, and the structural performance of the two supports must be guaranteed to meet the arrangement requirements, making the construction process more complex and reducing assembly efficiency. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, one objective of the present invention is to provide a drive shaft assembly with a bracket inside, which, due to its high structural strength, simplifies the structure of the drive shaft assembly.

[0004] Another objective of this utility model is to provide a powertrain in which a drive shaft assembly as shown above is provided.

[0005] Another objective of this invention is to provide a vehicle having a powertrain as shown above.

[0006] A drive shaft assembly according to an embodiment of the present invention includes: a first drive shaft, a second drive shaft, and a bracket. The second drive shaft and the first drive shaft are coaxially arranged and are drively connected. The bracket is connected to the first drive shaft and is used to connect and limit the first drive shaft and the second drive shaft. The bracket includes: a straight plate and a flange. The flange is disposed on the outer periphery of the straight plate, and the first drive shaft is connected to the flange.

[0007] According to the embodiments of the present invention, the drive shaft assembly is adapted to have a flange built on the outer periphery of the straight plate, so that the flange can improve the structural strength and enhance the performance of the bracket. This allows the bracket to more reliably connect and support the first and second drive shafts, making the drive shaft assembly easier to arrange, simplifying the assembly process, and improving assembly efficiency. Furthermore, because the bracket has high structural strength, a single bracket can reliably connect and support the drive shaft, allowing multiple drive shafts to be connected using a single bracket during assembly, making the connection process simpler and more convenient.

[0008] In some embodiments, the straight plate is provided with connecting holes and fixing holes, the connecting holes are located at the center of the straight plate, and the fixing holes are spaced apart on the outside of the connecting holes.

[0009] In some embodiments, a connecting hole is provided on the straight plate, and the fastener is adapted to connect the bracket to the vehicle frame through the connecting hole to realize the assembly connection of the drive shaft assembly. In order to make the connection between the bracket and the vehicle frame more stable and reliable, multiple spaced fixing holes are provided around the connecting hole, so that the bracket can be further fixed in the fixing holes during the assembly process, thereby improving the arrangement reliability of the drive shaft assembly.

[0010] In some embodiments, there are four fixing holes.

[0011] In some embodiments, by setting four fixing holes, the fixing holes can be used to further fix and restrict the connection of the bracket as designed, so as to make the connection and assembly of the drive shaft assembly more reliable, simplify the assembly process, and improve assembly efficiency.

[0012] In some embodiments, the flange includes two oppositely disposed side edges and a bottom edge, the side edges being connected to the side of the straight plate, and the bottom edge being disposed at the bottom of the straight plate.

[0013] In some embodiments, the flange is adapted to include a side edge and a bottom edge, the side edge being constructed on the side of the straight plate and the bottom edge being constructed on the bottom of the straight plate, so that the bottom edge and the side edge can correspondingly enhance the structural strength of the bottom and side of the straight plate, thereby improving the structural performance of the bracket and thus improving the construction reliability of the drive shaft assembly.

[0014] In some embodiments, the side is inclined in a vertical direction, and the inclination direction of the side is outward.

[0015] In some embodiments, during the construction of the side, in order to facilitate the production and construction of the bracket, the side is adapted to be tilted and tilted towards the bottom edge, so that the side can be connected to the floor and the machine in a simpler and more reliable manner, so that the drive shaft assembly can be arranged more reliably in the vehicle.

[0016] In some embodiments, the bracket further includes a reinforcing rib, one end of which is connected to the bottom edge and the other end of which is connected to the straight plate.

[0017] In some embodiments, by connecting one end of the reinforcing rib to the bottom edge and the other end of the reinforcing rib to the straight plate, the reinforcing rib can correspondingly improve the structural strength of the bracket, thereby allowing the bracket to better rest on the drive shaft, and making the use of the drive shaft assembly more reliable.

[0018] In some embodiments, the cross-sectional shape of the reinforcing rib is triangular.

[0019] In some embodiments, the cross-section of the reinforcing rib is set as a triangle, so that the reinforcing rib can ensure a good improvement in the structural strength of the support while reducing the amount of material used in its production and lowering production costs.

[0020] In some embodiments, the bracket is formed from a single sheet metal piece.

[0021] In some embodiments, by constructing the bracket as a one-piece sheet metal part, the production steps of the bracket are reduced, the bracket production process is simplified, and the bracket has higher connection strength, resulting in higher structural strength of the bracket and thus improving the reliability of the drive shaft assembly.

[0022] The powertrain according to an embodiment of the present invention includes: a drive shaft assembly as described above.

[0023] According to the powertrain embodiment of this utility model, since the powertrain includes a drive shaft assembly as shown above, it is suitable to have a flange built on the outer periphery of the straight plate. This flange is designed to enhance structural strength, thereby improving the performance of the bracket. The bracket can then more reliably connect and support the first and second drive shafts, allowing for simpler arrangement of the drive shaft assembly, simplifying the assembly process, and improving assembly efficiency. Furthermore, because the bracket has high structural strength, a single bracket can reliably connect and support the drive shafts, allowing multiple drive shafts to be connected using a single bracket during assembly, making the connection process simpler and more convenient.

[0024] The vehicle according to an embodiment of the present invention includes: the powertrain as described above.

[0025] According to the vehicle embodiment of this utility model, since the powertrain shown above is provided inside the vehicle, it is suitable to have a flange built on the outer periphery of the straight plate, so that the flange can improve the structural strength and enhance the performance of the bracket. This allows the bracket to more reliably connect and support the first and second drive shafts, making the drive shaft assembly easier to arrange, simplifying the assembly process, and improving assembly efficiency. Furthermore, because the bracket has high structural strength, a single bracket can reliably connect and support the drive shaft, allowing multiple drive shafts to be connected using a single bracket during assembly, making the connection process simpler and more convenient.

[0026] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0027] The above and / or additional aspects and advantages of this utility model will become apparent and readily understood from the description of the embodiments taken in conjunction with the following drawings, in which: Figure 1 This is a structural schematic diagram of the bracket according to an embodiment of the present utility model; Figure 2 This is a structural schematic diagram of the bracket according to an embodiment of the present utility model; Figure label: Bracket 300, Straight plate 310, connecting hole 311, fixing hole 312, Flanged edge 320, side edge 321, bottom edge 322. Reinforcing rib 330. Detailed Implementation

[0028] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0029] The following is for reference. Figures 1-2 The drive shaft assembly according to an embodiment of the present invention includes: a first drive shaft, a second drive shaft, and a bracket 300.

[0030] Specifically, the second drive shaft and the first drive shaft are coaxially arranged and are connected in a driving manner. The bracket 300 is connected to the first drive shaft and is used to connect and limit the first drive shaft and the second drive shaft. The bracket 300 includes a straight plate 310 and a flange 320. The flange 320 is located on the outer periphery of the straight plate 310, and the first drive shaft is connected to the flange 320.

[0031] It should be noted that in the prior art, in a drive shaft assembly consisting of multiple drive shafts, especially a drive shaft assembly consisting of three drive shafts, two supports 300 are required to connect and restrict the two drive shafts so that the multiple drive shafts can be arranged according to the design. However, using two supports 300 results in relatively high cost, and the structural performance of the two supports 300 must be guaranteed to meet the arrangement requirements, which makes the construction process more complicated and reduces assembly efficiency.

[0032] Therefore, this application provides a drive shaft assembly suitable for including: a first drive shaft, a second drive shaft, and a bracket 300. During use, the bracket 300 is suitable for connecting the first drive shaft. Because the bracket 300 has a flange 320 to improve structural strength, the connection constraint of the bracket 300 for the first and second drive shafts is more reliable, making the structure of the drive shaft assembly simpler and more reliable, simplifying the assembly process, improving assembly efficiency, and resulting in lower production costs.

[0033] Specifically, in the construction of the bracket 300, it is suitable to include a straight plate 310 and a flange 320. The flange 320 is suitable to be connected to the outer periphery of the straight plate 310, so that the flange 320 can improve the structural strength of the straight plate 310, thereby giving the bracket 300 higher performance in connecting the driveshaft assembly to the frame, simplifying the assembly process, and improving assembly efficiency. At the same time, because the bracket 300 has high structural strength, during the assembly of the driveshaft assembly, a single bracket 300 can be used to connect and support the driveshaft, thereby simplifying the arrangement of the driveshaft assembly.

[0034] According to the embodiments of the present invention, the drive shaft assembly is adapted to have a flange 320 constructed on the outer periphery of the straight plate 310. This flange 320 enhances structural strength, thereby improving the performance of the bracket 300. The bracket 300 can then more reliably connect and support the first and second drive shafts, allowing for simpler arrangement of the drive shaft assembly, simplifying the assembly process, and improving assembly efficiency. Furthermore, due to the high structural strength of the bracket 300, a single bracket 300 can reliably connect and support the drive shafts, allowing multiple drive shafts to be connected using a single bracket 300 during assembly, making the connection process simpler and more convenient.

[0035] In some embodiments, the straight plate 310 is provided with a connecting hole 311 and a fixing hole 312. The connecting hole 311 is located at the center of the straight plate 310, and the fixing holes 312 are spaced apart on the outer side of the connecting hole 311. That is, the straight plate 310 is provided with a connecting hole 311, and the fastener is adapted to connect the bracket 300 to the vehicle frame through the connecting hole 311 to realize the assembly connection of the drive shaft assembly. In order to make the connection between the bracket 300 and the vehicle frame more stable and reliable, a plurality of spaced fixing holes 312 are provided around the connecting hole 311, so that the bracket 300 can be further fixed in the fixing holes 312 during the assembly process, thereby improving the arrangement reliability of the drive shaft assembly.

[0036] In some embodiments, there are four fixing holes 312. By setting four fixing holes 312, the fixing holes 312 can further fix and restrict the connection of the bracket 300 according to the design, so that the connection and assembly of the drive shaft assembly is more reliable, the assembly process is simplified, and the assembly efficiency is improved.

[0037] In some embodiments, the flange 320 includes two opposing side edges 321 and a bottom edge 322. The side edges 321 are connected to the side of the straight plate 310, and the bottom edge 322 is located at the bottom of the straight plate. Thus, the flange 320 is adapted to include side edges 321 and a bottom edge 322, with the side edges 321 constructed on the side of the straight plate 310 and the bottom edge 322 constructed at the bottom of the straight plate 310. This allows the bottom edge 322 and the side edges 321 to correspondingly enhance the structural strength of the bottom and side of the straight plate 310, thereby improving the structural performance of the bracket 300 and enhancing the construction reliability of the drive shaft assembly. In some specific embodiments, it is suitable to connect the side edges 321 and the bottom edge 322 so that the side edges 321, the bottom edge 322, and the straight plate 310 form a triangular structure to enhance structural strength.

[0038] In some embodiments, the side 321 is inclined in the vertical direction, and the inclination direction of the side 321 is outward. Thus, during the construction of the side 321, in order to facilitate the production and construction of the bracket 300, the side 321 is inclined and tilted towards the bottom edge 322, so that the side 321 can be connected and restricted to the floor and the machine in a simpler and more reliable manner, so that the drive shaft assembly can be arranged more reliably in the vehicle.

[0039] In some embodiments, the bracket 300 further includes a reinforcing rib 330, one end of which is connected to the bottom edge 322, and the other end of which is connected to the straight plate 310. By connecting one end of the reinforcing rib 330 to the bottom edge 322 and the other end to the straight plate 310, the reinforcing rib 330 can correspondingly enhance the structural strength of the bracket 300, thereby allowing the bracket 300 to better support the drive shaft, making the use of the drive shaft assembly more reliable.

[0040] In some embodiments, the cross-sectional shape of the reinforcing rib 330 is triangular. By setting the cross-section of the reinforcing rib 330 to a triangular shape, the reinforcing rib 330 can ensure good structural strength of the support 300 while reducing the amount of material needed for its production, thus lowering production costs.

[0041] In some embodiments, the bracket 300 is integrally formed from sheet metal. By constructing the bracket 300 as an integrally formed sheet metal part, the production steps of the bracket 300 are reduced, the production process of the bracket 300 is simplified, and the bracket 300 has higher connection strength, resulting in higher structural strength and thus improving the reliability of the drive shaft assembly.

[0042] The powertrain according to an embodiment of the present invention includes: the drive shaft assembly as described above. Thus, since the powertrain includes the drive shaft assembly as shown above, it is suitable to have a flange 320 constructed on the outer periphery of the straight plate 310, thereby increasing the structural strength of the flange 320 and improving the performance of the bracket 300. This allows the bracket 300 to more reliably connect and support the first and second drive shafts, making the drive shaft assembly easier to arrange, simplifying the assembly process, and improving assembly efficiency. Furthermore, because the bracket 300 has high structural strength, a single bracket 300 can reliably connect and support the drive shaft, allowing multiple drive shafts to be connected using a single bracket 300 during assembly, making the connection process simpler and more convenient.

[0043] The vehicle according to an embodiment of the present invention includes the powertrain as described above. Thus, since the powertrain as shown above is provided within the vehicle, it is suitable to construct the flange 320 on the outer periphery of the straight plate 310, thereby increasing the structural strength of the flange 320 and improving the performance of the bracket 300. This allows the bracket 300 to more reliably connect and support the first and second drive shafts, simplifying the arrangement of the drive shaft assembly, streamlining the assembly process, and improving assembly efficiency. Furthermore, because the bracket 300 has high structural strength, a single bracket 300 can reliably connect and support the drive shaft, allowing multiple drive shafts to be connected using a single bracket 300 during assembly, making the connection process simpler and more convenient.
