The invention provides a power assembly suspension structure of a hydrogen fuel cell vehicle. The power assembly suspension structure comprises a hydrogen supply pipeline, a battery, a battery bracket, a motor, a left suspension, a right suspension, a vehicle body cross beam and a vehicle frame, the battery and battery bracket comprises a battery and a battery bracket; the hydrogen supply pipeline is fixed on the frame; the motor is fixedly connected to the battery and the lower surface of the battery bracket; the battery and the battery bracket are connected with the left frame through a left suspension, and the left suspension is a trapezoidal rubber suspension; the battery and the battery bracket are connected with the right frame through a right suspension, and the right suspension is a hydraulic suspension; different technical schemes are set according to different positions of the elastic center connecting line of the left suspension and the right suspension in front of and behind the mass center of the power assembly. According to the power assembly suspension structure, the rotation amount of the power assembly around the Y axis can be effectively controlled, so that it is guaranteed that the motion amount of a hydrogen supply pipeline is as small as possible, and risks are avoided; and the damage hidden danger of the hydrogen supply pipeline of the hydrogen fuel cell vehicle is effectively eliminated.
本发明提供一种氢燃料电池车动力总成悬置结构,包括供氢管路、电池及电池支架、电机、左悬置、右悬置、车身横梁和车架;所述电池及电池支架包括电池和电池支架;所述供氢管路固定在车架上;所述电机固定连接在电池及电池支架下表面上;所述电池及电池支架通过左悬置与左侧车架相连接,所述左悬置为梯形橡胶悬置;所述电池及电池支架通过右悬置与右侧车架相连接,所述右悬置为液压悬置;本发明根据左悬置和右悬置弹性中心连线在动力总成质心前后位置的不同,设置不同的技术方案。本发明的动力总成悬置结构能够有效的控制动力总成在绕Y轴的旋转量,来保证供氢管路的运动量尽可能小,避免风险的出现;有效地排除了氢燃料电池车供氢管路的破坏隐患。
