[0027] Reference below Figure 1-Figure 3 A control arm 99 according to an embodiment of the present invention is described, and the control arm 99 is applied to a vehicle.

[0028] like Figure 1-Figure 3 As shown, the control arm 99 according to the embodiment of the present utility model includes: a control arm body 10, a first mounting member 20, a second mounting member 30 and a connecting member.

The bushing is sleeved on the second mounting member 30, and the shock absorber 98 is connected to the bushing so that the shock absorber 98 and the second mounting member 30 are assembled together.

[0033] It should be noted that the present application optimizes the structure of the control arm 99 and the connection form between the control arm 99 and the shock absorber 98 by connecting the first mounting member 20 to the control arm body 10 (for example, by welding), connecting the first mounting member 20 and the second mounting member 30 through a connecting member, and making the second mounting member 30 suitable for assembly with the shock absorber 98 of the suspension system 100 of the vehicle. The load on the shock absorber 98 can be transmitted to the second mounting member 30, the connecting member, the first mounting member 20, and the control arm body 10 in sequence, so that the load transmitted from the shock absorber 98 to the control arm body 10 can be dispersed, which is beneficial to avoid the problem of stress concentration, and further avoids the problem of weld cracking caused by load concentration in the prior art, and can improve the fatigue durability performance of the suspension system 100.
