[0020] Figure 2 for Figure 1 Enlarged diagram of point A in the middle. Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings. The large-sliding assembly high-performance assembly includes an intermediate shaft. One end of the intermediate shaft is provided with a first universal joint 2, and the other end is provided with a second universal joint. The intermediate shaft includes a bushing 3, a first half-shaft 4, and a second half-shaft 5. The bushing includes a detachably connected first bushing 31 and a second bushing 32. One end of the first half-shaft is connected to the first universal joint, and the other end extends into the first bushing and engages with it. One section of the second half-shaft is connected to the second universal joint, and the other end extends into the second bushing and engages with it. The first half-shaft's one end extending into the first universal joint and engaging with it is prior art and will not be described further. Its other end extends into the first bushing for sliding engagement, forming a sliding module. The second half-shaft is similarly designed. The two sliding modules can be installed together for overall assembly, resulting in a large sliding range and convenient assembly.

[0022] In this embodiment, as shown in the figure, the inner wall of the first bushing is provided with a channel, the first bushing is provided with a first retainer 311, the first retainer is provided with a rolling element 312, and the first half-shaft extending into the first bushing is provided with a first star-shaped sleeve 41. The rolling element cooperates with the star-shaped sleeve and the rolling element cooperates with the channel. This results in more stable operation and better performance.

[0023] In this embodiment, as shown in the figure, the second half-shaft is mirror-image of the first half-shaft. The second bushing contains a second retainer, etc., identical to the first bushing.

[0024] In this embodiment, as shown in the figure, the first bushing and the second bushing are connected by a fastener 33. Specifically, this fastener can be a bolt or the like.

[0025] In this embodiment, as shown in the figure, a cover 313 is also included. The cover engages with the inner wall of the first bushing to limit the position of the first retainer. The cover is installed inside the first bushing, serving both a sealing function and a limiting function.

[0026] In this embodiment, as shown in the figure, a dust cover 5 is also included. One end of the dust cover is connected to the first half-shaft, and the other end is connected to the second bushing. This prevents foreign objects from entering.
