Electric vehicle auxiliary frame structure

The invention provides an electric vehicle auxiliary frame structure which comprises an auxiliary frame and a suspension bushing, wherein the suspension bushing comprises a mounting sleeve and a bushing cushion arranged in the mounting sleeve; the bushing cushion is in interference fit with the mounting sleeve; the axis of the mounting sleeve is perpendicular to the auxiliary frame; the mounting sleeve is welded to the auxiliary frame; the bushing cushion is connected with supporting legs of a power assembly of a vehicle. The auxiliary frame is directly connected with the supporting legs of the power assembly through the suspension bushing, suspension assembly supports and suspension connecting supports in the prior art are not required, therefore, only a small number of parts of the auxiliary frame structure is required, meanwhile, accumulation of assembly errors is effectively reduced, the assembly difficulty is well reduced, and the assembly efficiency is effectively improved. 本发明提供了一种电动车副车架结构，其包括副车架、悬置衬套，
