The invention provides a heavy-duty truck balance shaft support and belongs to the technical field of heavy-duty truck balance suspension. The technical scheme comprises a heavy-duty truck balance shaft support; the heavy-duty truck balance shaft support comprises a vehicle frame connecting member; a bearing support structure which is installed at one side of the vehicle frame connecting member; an axle housing mounting assembly which is installed at the connecting position of the vehicle frame connecting member and the bearing support structure; and a push rod mounting support seat structurewhich is installed at a bottom of the axial housing mounting assembly. The beneficial effects of the present invention are: the outer surface of the present invention is a convex arc-shaped connectingplate, a hollow support bearing case carrying a support structure, a concave connector, an inner bearing block, and a wing-shaped support. The shaft shell mounting assembly can transmit the load of the push rod to the upper part of the balance shaft support, so as to avoid deformation of the push rod mounting support seat by the force, so that the overall balance shaft support is more balanced.
