The invention belongs to the technical field of vehicle suspensions, and particularly relates to a front independent suspension system for a heavy truck and the heavy truck. The front independent suspension system for the heavy truck comprises a frame assembly, a steering mechanism and a steering gear, the steering mechanism is of an asymmetric structure and comprises a rocker arm, a longitudinal pull rod, a swing arm assembly, a left steering unit and a right steering unit, the left steering unit comprises a left steering knuckle arm and a left steering transverse pull rod, and the right steering unit comprises a right steering knuckle arm and a right steering transverse pull rod. The left steering tie rod and the right steering tie rod are both connected with the swing arm assembly, the length of the left steering knuckle arm is not equal to the length of the right steering knuckle arm, and the length of the left steering tie rod is not equal to the length of the right steering tie rod. The heavy truck adopts the front independent suspension system for the heavy truck, so that the use cost of parts is saved while the comfort and the maneuverability of the whole truck are ensured.
