The invention relates to a hydrogen fuel truck chassis arrangement structure which comprises frame longitudinal beams with the same front and back width, and a hydrogen fuel cell is arranged at an engine compartment below a cab; the hydrogen storage tanks are arranged on the two sides of the vehicle frame, compared with the mode that the hydrogen storage tanks are arranged on the upper rear portion of the vehicle frame, the size of a container can be increased, the outermost width of the hydrogen storage tank protection frame is arranged according to the maximum value of 2550 mm of the regulation, it is guaranteed that the hydrogen storage tanks do not exceed the upper wing face of the vehicle frame by 70 mm and do not interfere with the container, meanwhile, the ground clearance is larger than 250 mm, and the trafficability of the vehicle is guaranteed. The frame adopts a front-back equal-width design, the structure is simple, and the manufacturing cost is low. The power battery and the hydrogen fuel battery are both placed in the frame, the safety coefficient is high, and the hydrogen fuel battery is additionally provided with the battery protection frame, so that the safety of the fuel battery in emergency is improved. The power battery cooling unit is arranged in front of the power battery and is close to the power battery, so that the cooling management length is reduced, the cost is reduced, and the thermal management effect is good.
本发明涉及一种氢燃料载货车底盘布置结构,包括前后等宽的车架纵梁,氢燃料电池布置于驾驶室下方的发动机舱处;通过储氢罐布置在车架两侧,相比布置在车架后上位置,能够增加货箱尺寸,且储氢罐保护框最外宽按照法规最大值2550mm进行布置,保证储氢罐不超过车架上翼面70mm,不干涉货箱,同时离地间隙大于250mm,保证车辆通过性。车架采用前后等宽设计,结构简单,制造成本低。动力电池与氢燃料电池均放置在车架内部,安全系数高,且氢燃料电池加装电池保护架,提升紧急情况下燃料电池的安全性。动力电池冷却机组布置在动力电池前面,距离动力电池近,减少冷却管理长度,成本降低,且热管理效果好。
