The invention discloses a whole chassis arrangement structure of a fuel cell truck, comprising a vehicle frame, a fuel cell engine, a power battery, a hydrogen storage device, an electric drive axle system, a motor controller and a cooling system. The fuel cell engine is arranged at the position of the traditional diesel vehicle engine, the power battery is arranged behind the fuel cell engine, two hydrogen storage devices are symmetrically arranged on both sides of the power battery, and the electric drive axle system is arranged between the two rear wheels , the motor controller is arranged at the rear of the frame. The cooling system includes auxiliary machine cooling system, electric stack cooling system and motor cooling system. The auxiliary machine cooling system is arranged at the front suspension of the frame, the electric stack cooling system is arranged in front of the fuel cell engine, and the motor cooling system is arranged at the bottom of the frame. The tail is also arranged behind the rear wheels. The invention has a low center of gravity of the whole vehicle, high safety, and improves the space utilization rate of the cargo box. Three sets of cooling systems are used to dissipate heat for different components.
Description
technical field [0001] The invention belongs to the field of production and manufacture of fuel cell trucks, and relates to a full chassis layout structure of fuel cell trucks. Background technique [0002] With the gradual acceleration of the commercialization of fuel cell vehicles, many companies have begun to actively deploy the fuel cell industry. In the field of light-duty fuel cell trucks, Beiqi Foton, Dongfeng Motor Corporation, Youth Company, FAW Jiefang, etc. have successively launched light-duty fuel cell trucks, adopting the extended-range technology route to meet the needs of urban logistics and distribution. The fuel cell systems of existing light-duty fuel cell trucks are all rear-mounted. One is that the fuel cell engine, hydrogen system, cooling system, and DC-DC converter are integrally arranged between the cab and the cargo box. The other is that the fuel cell engine is arranged at the diesel vehicle engine, and the hydrogen system, DC-DC converter, etc. a...
