[0022] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0023] like Figure 1-Figure 3As shown, the embodiment of the present invention provides an aluminum alloy front lower control arm assembly, comprising:

[0024] The control arm body 1 has a base 2 fixedly provided at one end thereof for mounting a ball stud 3. The mounting method is conventional and will not be described in detail herein. The ball stud 3 is mounted in the base 2.

[0025] Dustproof assembly, the dustproof assembly includes a dust cover 4, an annular sealing ring 5 and a cover 7. The dust cover 4 is sleeved on the ball stud 3. A sealing assembly is provided between the upper end of the dust cover 4 and the ball stud 3. The sealing assembly includes a sleeve 10, a limit ring 11 and a fixing ring 13. The top of the dust cover 4 is fixedly provided on the outside of the sleeve 10. The sleeve 10 is sleeved on the ball stud 3. The bottom end of the sleeve 10 is as shown Figure 3 As shown in the bucket-shaped tilt setting, the bottom slope of the sleeve 10 is fixed with a sealing gasket, and the limiting ring 11 is fixedly sleeved on the outside of the ball pin 3. The outside of the limiting ring 11 is as shown in FIG. Figure 3 As shown, the bottom end of the sleeve 10 is arranged in a beveled manner, and the bottom end of the sleeve 10 is matched with the limiting ring 11 so that the bottom end of the sleeve 10 can fit the bevel of the limiting ring 11. The outer side of the limiting ring 11 is set against the sealing gasket, thereby playing a sealing role. The fixing ring 13 is sleeved on the ball stud 3. The outer side of the ball stud 3 is provided with a spiral pattern 12. The fixing ring 13 is sleeved on the spiral pattern 12 and threadedly connected, so that the fixing ring 13 can be screwed onto the spiral pattern 12 and the sleeve 10 and the limiting ring 11 are tightly pressed;

[0026] The annular sealing ring 5 is fixedly arranged at the bottom of the dust cover 4, and a limiting groove 6 is provided on the outer side of the top of the base 2.
