Description

Technical Field

[0001] This utility model relates to the field of drive shaft technology, specifically a lightweight drive shaft. Background Technology

[0002] The driveshaft is a core component of a car's transmission system, responsible for transmitting engine power from the transmission to the drive wheels, thus driving the vehicle.

[0003] When the wheelbase of an automotive driveshaft is designed to be too long, a support structure is usually required in the middle of the driveshaft. In the existing technology, the driveshaft support structure is installed under the crossbeam of the chassis. However, the driveshaft is currently installed by mounting brackets to the crossbeam of the chassis. In actual use, the mounting brackets need to be set to correspond to the mounting holes of the crossbeam of the chassis. When in actual use, the position of the shaft tube needs to be adjusted. When the position of the shaft tube for mounting the support structure is adjusted, the support structure cannot be installed with the crossbeam of the chassis and cannot effectively support the driveshaft. Therefore, we propose a lightweight driveshaft. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a lightweight drive shaft, which solves the problem that the mounting bracket needs to be designed to correspond to the mounting holes of the vehicle frame crossbeam. In actual use, the position of the shaft tube needs to be adjusted, which can lead to the support structure being unable to be installed with the vehicle frame crossbeam and thus failing to effectively support the drive shaft.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] This application provides a lightweight drive shaft, which solves the problem that the mounting bracket 741 needs to be set with mounting holes corresponding to the frame crossbeam. In actual use, the position of the shaft tube needs to be adjusted. When the position of the shaft tube installed in the support structure is adjusted, the support structure cannot be installed with the frame crossbeam and cannot effectively support the drive shaft. The connection bracket 731 can be rotated along the plug rod through the rotating hole 732. The angle of the connection bracket 731 can be adjusted by rotating the connection bracket 731 along the plug rod, thereby facilitating the adjustment of the connection between the connection bracket 731 and the frame crossbeam. The rubber support seat 71 is fixed between the frame crossbeams through the two connection brackets 731.

[0032] By adjusting the rotating rod 742 to the appropriate position corresponding to the mounting slot 744, the position of the mounting bracket 741 on the connecting bracket 731 is adjusted to adapt to the installation of frame crossbeams with different spacing. When the first shaft tube 1 drives the rubber support seat 71 to rotate, the lightweight drive shaft is installed on the frame crossbeam through the cooperation of the rubber support seat 71, support shell 72, connecting component 73 and mounting component 74, thus supporting the drive shaft.

[0033] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0034] This utility model discloses a lightweight drive shaft.

[0035] Example 1, according to Appendix Figure 1-4 As shown, it includes:

[0036] First shaft tube 1;

[0037] Second shaft tube 2;

[0038] The sliding fork 3 is located at one end of the second shaft tube 2;

[0039] The first universal joint 4 has its two ends connected to the first shaft tube 1 and the sliding fork 3 respectively; through the action of the first universal joint 4, the angle of the first shaft tube 1 relative to the second shaft tube 2 and the sliding fork 3 can be adjusted.

[0040] Support unit 7 is disposed on the outer peripheral wall of the first shaft tube 1, and the support unit 7 is located on the first shaft tube 1 at one end near the first universal joint 4.

[0041] The support unit 7 includes a rubber support seat 71, which is sleeved on the outer peripheral wall of the first shaft tube 1. A support shell 72 is installed on the outer peripheral wall of the rubber support seat 71. A connecting component 73 is rotatably connected to the support shell 72. The connecting component 73 is used to support the rubber support seat 71 and the support shell 72.

[0042] A second universal joint 5 is provided at the end of the first shaft tube 1 away from the first universal joint 4, and a connecting flange is provided at the end of the second universal joint 5.

[0043] The second universal joint 5 is installed via a connecting flange. The second universal joint 5 is used to drive the first shaft tube 1 to rotate along the flange and adjust the angle of the first shaft tube 1.

[0044] The second shaft tube 2 is provided with a third universal joint 6 at the end away from the first universal joint 4, and a connecting flange is provided at the end of the third universal joint 6.

[0045] The third universal joint 6 is installed via a connecting flange. The third universal joint 6 is used to drive the first shaft tube 1 to rotate along the flange and adjust the angle of the second shaft tube 2.

[0046] The connecting assembly 73 includes a connecting frame 731. Both the connecting frame 731 and the support shell 72 have rotating holes 732. A plug rod is inserted into the inner wall of the rotating hole 732.

[0047] The connecting bracket 731 rotates along the plug rod through the rotating hole 732. The angle of the connecting bracket 731 can be adjusted by rotating the connecting bracket 731 along the plug rod, thereby facilitating the adjustment of the connection between the connecting bracket 731 and the frame crossbeam. The rubber support seat 71 is fixed between the frame crossbeams through the two connecting brackets 731.

[0048] The support shell 72 has a positioning hole 734, and a connector rod is inserted into the positioning hole 734.

[0049] An arc-shaped limiting strip 733 is fixedly connected to the bottom end face of the connecting frame 731. The arc-shaped limiting strip 733 has a sliding groove, which is set to correspond to the positioning hole 734.

[0050] When the connecting frame 731 rotates along the insertion rod through the rotating hole 732, the connecting frame 731 drives the arc-shaped limiting strip 733 to rotate accordingly. At this time, the arc-shaped limiting strip 733 slides along the insertion rod inserted in the positioning hole 734 to ensure the stability of the angle adjustment of the connecting frame 731.

[0051] Both ends of the plug rod are provided with threaded grooves, and the outer peripheral wall of the threaded groove is threaded with a nut seat, which fits against the outer wall of the support shell 72.

[0052] When the adjusting connecting frame 731 is in the appropriate adjustment, the nut seat is rotated so that it rotates along the threaded groove on the plug rod, so that the nut seats at both ends of the plug rod contact and press against the two sides of the support shell 72, thereby clamping and fixing the support shell 72 and the connecting frame 731. The supporting shell 72 cooperates with the arc-shaped limiting strip 733 to fix the connecting frame 731 a second time, thereby ensuring the stable installation of the connecting frame 731 and the support shell 72.

[0053] Example 2, according to Appendix Figure 1-4 As shown, it includes:

[0054] First shaft tube 1;

[0055] Second shaft tube 2;

[0056] The sliding fork 3 is located at one end of the second shaft tube 2;

[0057] The first universal joint 4 is connected at both ends to the first shaft tube 1 and the sliding fork 3, respectively;

[0058] Support unit 7 is disposed on the outer peripheral wall of the first shaft tube 1, and the support unit 7 is located on the first shaft tube 1 at one end near the first universal joint 4.

[0059] The support unit 7 includes a rubber support seat 71, which is sleeved on the outer peripheral wall of the first shaft tube 1. A support shell 72 is installed on the outer peripheral wall of the rubber support seat 71. A connecting component 73 is rotatably connected to the support shell 72. The connecting component 73 is used to support the rubber support seat 71 and the support shell 72.

[0060] A mounting component 74 is provided at the end of the connecting component 73 away from the support shell 72. The mounting component 74 includes a mounting bracket 741, and a rotating rod 742 is fixedly connected to the end of the mounting bracket 741.

[0061] The rotating rod 742 has a plug hole 743, and the connecting bracket 731 has multiple mounting slots 744, with the plug hole 743 corresponding to the mounting slot 744.

[0062] By adjusting the rotating rod 742 to the appropriate position corresponding to the mounting slot 744, the position of the mounting bracket 741 on the connecting bracket 731 can be adjusted to accommodate the installation of crossbeams with different spacing.

[0063] A connector rod is inserted into the connector hole 743, and the connector rod is slidably connected inside the corresponding mounting slot 744.

[0064] By pulling the plug rod to slide in the mounting slot 744, the rotating rod 742 slides with the plug rod in the mounting slot 744, thereby adjusting the position of the mounting bracket 741;

[0065] By rotating the mounting bracket 741 along the insertion rod inserted in the insertion hole 743, the mounting bracket 741 is fitted onto the outer wall of the frame crossbeam and installed by threads.

[0066] Then, the lightweight drive shaft is installed on the frame crossbeam by means of the rubber support 71, support shell 72, connecting component 73 and mounting component 74.
