[0022] Please see Figures 1-4 As shown, an automotive cooling connection shaft includes a hub 1, with bolts 2 running through the surface of the hub 1. One side of a fan blade 4 is fixedly connected to the inner side of the hub 1, and a universal joint 5 is fixedly connected to the other side of the fan blade 4. A drive shaft 6 is fixedly connected to the inner side of the universal joint 5, and a drive gear 7 is fixedly connected to the surface of the drive shaft 6. A splined shaft 8 is fixedly connected to one end of the drive shaft 6, and a bearing assembly 9 is engaged with the surface of the splined shaft 8. A support frame 10 is fixedly connected to the side of the bearing assembly 9, and an oil reservoir 11 is fixedly installed inside the support frame 10.

[0023] Furthermore, the bearing assembly 9 includes an outer ring 91, a roller 93 is slidably connected to the inner wall of the outer ring 91, an inner ring 92 is slidably connected to the inner side of the roller 93, a groove 95 is provided on the surface of the inner ring 92, and a through pipe 94 is fixedly connected to the top of the outer ring 91.

[0024] During operation, the structure design of the groove 95 on the surface of the inner ring 92 and the through pipe 94 on the top of the outer ring 91 facilitates the guidance of lubrication to cover the surfaces of the outer ring 91, the inner ring 92 and the spline shaft 8, reducing the friction of the device and thus reducing the heat generation of the device.

[0025] Furthermore, a number of fins 96 are evenly arranged around the outer wall of the outer ring 91, and the surface of the fins 96 is inclined.

[0026] During operation, the inclined structure of the fins 96 on the outer wall of the outer ring 91 improves the heat dissipation effect of the fins 96.

[0027] Furthermore, the top of the oil storage tank 11 is provided with a through hole 112, the bottom of the oil storage tank 11 is fixedly connected with an oil outlet pipe 111, and the inside of the support frame 10 is provided with a through hole 101, the position of the through hole 101 corresponding to the installation position of the oil outlet pipe 111.

[0028] During operation, the structural design, in which the opening position of the perforation 101 corresponds to the installation position of the oil outlet pipe 111, facilitates the positioning and installation of the oil storage tank 11 by the support frame 10.

[0029] Furthermore, the surface of the hub 1 is provided with several through slots 3 at equal intervals, and the positions of the through slots 3 correspond to the positions of the fan blades 4;

[0030] During operation, the structural design, which uses the slots 3 on the surface of the hub 1 to correspond to the positions of the fan blades 4, reduces the weight of the hub 1 and improves the heat dissipation of the fan blades 4.

[0031] Furthermore, the inner wall of the inner ring 92 is slidably connected to the surface of the spline shaft 8, and the inner ring 92 is rotatably connected to the outer ring 91 via the roller 93;

[0032] During operation, the inner ring 92 is slidably connected to the surface of the spline shaft 8 through the inner wall of the inner ring 92, which facilitates the free movement of the inner ring 92 within a suitable working range.

[0033] Working principle: The hub 1 is installed in a suitable working area by bolts 2, and the support frame 10 is fixedly installed inside the car. The car engine drives the drive gear 7 to work. At this time, the drive gear 7 drives the transmission shaft 6 to rotate the hub 1, which drives the fan blade 4 to work. The through groove 3 opened on the surface of the hub 1 reduces the weight of the hub 1 and improves the air flow inside the device, thereby improving the heat dissipation effect of the device. Lubricating oil is added to the oil storage tank 11 through the through hole 112. The lubricating oil enters the through pipe 94 through the oil outlet pipe 111. By flowing in the through pipe 94, the lubricating oil covers the inner wall of the outer ring 91, the outer wall of the inner ring 92, the surface of the roller 93 and the surface of the spline shaft 8, reducing the friction between the devices and thus reducing the heat generation of the device. The inclined structure design of the fins 96 on the outer wall of the outer ring 91 increases the area of ​​the fins 96 and improves the heat dissipation effect of the fins 96.
