The invention relates to a combinable vehicle chassis vehicle which can be operated independently. The combinable vehicle chassis comprises a front suspension system, a swinging system, a tightening system, a drive system, a brake system, a steering system, a combination system, a signal synchronous port system and a rear suspension system, and is characterized in that the front suspension system and the rear suspension system are respectively arranged on the front end and the rear end of a vehicle and respectively connected with a front single wheel and a rear single wheel, the chassis device comprises a front swinging system and a rear swinging system, the front suspension system which is arranged on the front end of the vehicle is connected with a vehicle body mechanism skeleton through the front swinging system, the rear suspension system is connected with the vehicle body mechanism skeleton through the rear swinging system, and the tightening system, the combination system and the signal synchronous port system are respectively arranged on two sides of a vehicle chassis. When a device is independently driven, due to the two-wheel structural form, the advantages of low cost, small size and high utilization rate of a battery can be realized, and the advantage for improving the market popularization rate, improving the trip convenience and flexibility and reducing the storage space and the application space can be realized.
