[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] This application discloses a lower control arm assembly for automobile steering.

[0022] Reference Figure 1 and Figure 2 The system includes a control arm 1 and a ball joint assembly 2. The control arm 1 includes a housing 3 and a splicing cover 4, with the splicing cover 4 located inside the opening of the housing 3. The ball joint assembly 2 includes a connecting body 5 and a ball pin 6. The connecting body 5 consists of a connecting plate 7 and a ball joint seat 8. The connecting plate 7 is located between the housing 3 and the splicing cover 4. The side wall of the ball joint seat 8 is integrally fixed to the outer end of the connecting plate 7. One end of the ball pin 6 is rotatably connected inside the ball joint seat 8. Three fixing bolts 9 are threaded through the end of the control arm 1 near the connecting body 5. One end of each fixing bolt 9 passes through the splicing cover 4, the connecting plate 7, and the housing 3 in sequence. The side wall of the connecting plate 7 has a sliding groove 10 for the fixing bolts 9 to slide. The length direction of the sliding groove 10 is consistent with the connection direction between the control arm 1 and the connecting body 5. The connecting body 5 is installed between the housing 3 and the splicing cover 4. The fixing bolts 9 on the connecting body 5 slide within the sliding groove 10, thereby adjusting the distance between the connecting body 5 and the control arm 1.

[0023] Reference Figure 3The ball pin 6 is fitted with a protective ring seat 11. The protective ring seat 11 is in the shape of a frustum ring. The lower end of the protective ring seat 11 is fitted and fixed to the outer periphery of the outlet end of the ball head seat 8. The lower end of the protective ring seat 11 has a locking ring block 12 in the circumferential direction on the inner periphery. The outer periphery of the protective ring seat 11 has a groove 13 corresponding to the locking ring block 12. The ball head seat 8 has an annular groove 14 in the circumferential direction on the outer periphery of the outlet end. The locking ring block 12 is snapped and fixed in the annular groove 14.
