The invention relates to a drive motor rear suspension and suspension system, and the suspension system comprises a suspension skeleton which comprises an outer sleeve and a connecting steel plate, the connecting steel plate is provided with an arc groove matched with the outer wall surface of the outer sleeve, and a metal pipe used for being connected with a motor assembly is fixed to the end, away from the arc groove, of the connecting steel plate; and the suspension cushion is pressed in the outer sleeve in an interference manner and comprises an inner limiting pipe and a damping rubber body located in the inner limiting pipe, an inner limiting framework is connected in the damping rubber body, and an inner sleeve is embedded in the inner limiting framework. The suspension framework is formed by connecting the outer sleeve, the connecting steel plate and the metal pipe into a whole, the structure is simplified, the structural strength is high, light weight is achieved, and the modal and strength requirements of the suspension framework are met. And the assembly manufacturability is improved, and the spatial arrangement requirement is met. An inner limiting pipe and an inner limiting framework are arranged outside and inside a damping rubber body of the suspension cushion respectively, the deformation displacement of the damping rubber body is limited, and the requirements for reliability and durability of the suspension cushion are met.
