Full-chassis arrangement structure of fuel cell truck

Abstract

The invention discloses a full-chassis arrangement structure of a fuel cell truck. The full-chassis arrangement structure comprises a frame, a fuel cell engine, a power cell, hydrogen storage devices,an electric drive axle system, a motor controller and a cooling system. The fuel cell engine is arranged at a position of an engine of a traditional diesel vehicle, the power cell is arranged behindthe fuel cell engine, the two hydrogen storage devices are symmetrically arranged on the two sides of the power cell, the electric drive axle system is arranged between two rear wheels, and the motorcontroller is arranged at a tail of the frame. The cooling system comprises an auxiliary machine cooling system, a galvanic pile cooling system and a motor cooling system, the auxiliary machine cooling system is arranged at a front suspension of the frame, the galvanic pile cooling system is arranged in front of the fuel cell engine, and the motor cooling system is arranged at a tail part of the frame and is also arranged behind the rear wheels. The whole truck is low in gravity center and high in safety, and a container space utilization rate is increased. And three sets of cooling systems are adopted so that corresponding heat dissipation effects on different parts are achieved.

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...
