The invention provides a bracket for mounting function elements of a power station of an auxiliary machine. The bracket comprises a bracket mainboard, reinforcing ribs, ECU attached seats and an intercooler bracket, wherein the bracket mainboard provides a top mounting surface for an external intercooler, provides a side mounting surface for an external fuel filter, provides a front mounting surface for an external oil-water separator and a fuel pump, provides a bottom mounting surface for the bracket, and provides a back mounting surface for an external engine ECU; the reinforcing ribs are fixed between the front mounting surface and the bottom mounting surface of the bracket mainboard and between the front mounting surface and the top mounting surface of the bracket mainboard; the ECU attached seats are fixed on the back of the bracket mainboard, and are used for fixing the external engine ECU; the intercooler bracket is mounted at the top of the back of the bracket mainboard; and the upper surface of the intercooler bracket and the top mounting surface of the bracket mainboard are positioned on the same plane. The integration is high, and the length of a fuel pipeline is reduced.
