A disconnected type front axle assembly relates to a vehicle front shaft device and consists of two double-transverse-swing-arm disconnected type front axle assemblies which are respectively independent and symmetrically distributed left and right. Each double-transverse-swing-arm disconnected type front axle assembly comprises a hub, a brake disc assembly, a brake assembly, a steering knuckle assembly, a bearing arm, an upper transverse swing arm, a lower transverse swing arm, a steering pull rod, a steering converter, a transverse stabilizing rod hanging arm and a transverse stabilizing rod, wherein the upper transverse swing arm and the lower transverse swing arm can rotate freely around the bearing arm in a perpendicular direction, the hub, the brake disc assembly and the brake assembly are arranged on the steering knuckle assembly, the steering knuckle assembly is arranged on the bearing arm, one end of the upper transverse swing arm and one end of the lower transverse swing arm are rotationally connected with the bearing arm, other ends of the upper transverse swing arm and the lower transverse swing arm can be connected with the total vehicle through spherical hinges, the steering pull rod is connected between the steering converter and the steering knuckle assembly, and the transverse stabilizing rod is arranged on the bearing arm through the transverse stabilizing rod hanging arm. The disconnected type front axle assembly greatly increases running comfort and stability, is reasonable and reliable in structure, and is extremely suitable to be used in high-level coaches.
