Front lower swing arm introduce

The function of the front wheel lower control arm is to support the vehicle body, fix and support the wheels.

The function of the car lower control arm is to cushion vibration during car driving, Among them, the shock absorber is used to cooperate with the swing arm and play a buffering role. 2. Material: The swing arm has a variety of materials, including aluminum alloy, cast iron, double-layer stamped parts, single-layer stamped parts, all of which have advantages and disadvantages.
