[0020] The present invention will be further described below with reference to the accompanying drawings. The large-angle reverse-mounted high-performance assembly includes an intermediate shaft 1, with a first universal joint 2 at one end and a second universal joint 3 at the other end. The first universal joint includes a first housing 21, with a channel inside the first housing. A retainer is provided between the intermediate shaft extending into the first housing and the inner cavity of the first housing. The retainer has a first ball that mates with the channel. The assembly also includes an outer shaft structure, which includes a second housing 4 connected to the first housing. The second housing has a second channel 41 inside. A half-shaft 5 has a star-shaped sleeve 51 extending into the second housing at one end. A second retainer 52 is provided between the star-shaped sleeve and the inner wall of the second housing. The second retainer has a second ball 521, which mates with the second channel. The half-shaft of the outer shaft structure swings relative to the second housing, while the intermediate shaft can swing relative to the first housing, increasing the maximum swing angle. A star-shaped sleeve is also provided on the intermediate shaft, which is existing technology and will not be described further. If necessary, such a structure can also be provided on the first housing of the second universal joint to further increase the swing angle. Preferably, both the first and second universal joints can be ball-cage type universal joints.

[0021] In this embodiment, as shown in the figure, the second housing is detachably connected to the first housing. It is replaceable, facilitating maintenance and disassembly.

[0022] In this embodiment, as shown in the figure, the second housing is connected to the first housing by fasteners 9. These fasteners can be bolts and nuts.

[0023] In this embodiment, as shown in the figure, the intermediate shaft includes a bushing 11 and a first half-shaft 12. One end of the first half-shaft extends into the first housing, and the other end extends into the bushing, where it is driven by a key. The intermediate shaft can also be replaced, and the first half-shaft and the bushing can be driven by a transmission key 120.

[0024] In this embodiment, as shown in the figure, the inner wall of the bushing is provided with a third channel, and the intermediate shaft also includes a second half-shaft 13. A third retainer 14 is provided between the circumferential outer wall of the second half-shaft extending into the bushing and the inner wall of the bushing. The third retainer is provided with a third ball 141 that cooperates with the third channel.

[0025] In this embodiment, as shown in the figure, the second universal joint includes a third housing, and the outer shaft structure is also mounted on the outer end face of the third housing.

[0026] In this embodiment, as shown in the figure, the inner wall of the first housing is provided with eight channels. The ball-cage universal joint with eight steel balls reduces the total volume by 12% and the total mass by 16% compared to the ball-cage universal joint with six steel balls. Finite element analysis shows that the ball-cage universal joint with eight steel balls experiences less stress and has a longer fatigue life than the ball-cage universal joint with six steel balls.

[0027] In this embodiment, as shown in the figure, the first rolling ball is a steel ball.

[0028] In this embodiment, as shown in the figure, the first housing has a first flange 101, and the second housing has a second flange 102.
