The invention discloses an H-type power chassis with a function of adjusting a ground clearance and a wheel tread. The H-type power chassis comprises a chassis, and an engine, a clutch, a gear box, a differential mechanism, transfer cases, chain wheel transmission mechanisms and wheels which are arranged on the chassis, wherein power of the engine passes through the gear box to reach the differential mechanism, and then passes through the transfer cases on the two sides of the chassis to be transferred to the chain wheel transmission mechanisms on two sides through a left output shaft and a right output shaft of the differential mechanism, so that the power is transferred to the wheels which are connected with the chain wheel transmission mechanisms on two sides. The H-type power chassis has the advantages that: the front and rear wheels on the side have the same transmission ratio; when only one of the wheels on the same side slips and the other wheel does not slip, torque can be transferred to the wheel which does not slip, and driving power is generated by using adhesion of the wheel which does not slip, so that an automobile can start smoothly or runs continuously, and the pass-through performance of the automobile under the condition of a rugged road surface is improved. The ground clearance of the chassis and the wheel tread can be adjusted, and the H-type power chassis adapts to running of the rugged road surfaces of mountains, hills and the like, and has high pass-through performance, riding comfort, and stability.
