The invention provides an automobile suspension system. The automobile suspension system comprises a left front hydraulic cylinder provided with a left front piston rod, a left front cylinder, a right front hydraulic cylinder, a left rear hydraulic cylinder, a right rear hydraulic cylinder, a first hydraulic circuit, a second hydraulic circuit, a third hydraulic circuit, a fourth hydraulic circuit, at least one first energy accumulator, at least one second energy accumulator, at least one third energy accumulator, and at least one fourth energy accumulator. The left front piston rod is connected with a left front wheel assembly and the left front cylinder is connected with an automobile body. The structures of the right front hydraulic cylinder, the left rear hydraulic cylinder and the right rear hydraulic cylinder are similar to the structure of the left front hydraulic cylinder. The first hydraulic circuit is provided with two ports which are communicated with a rod cavity of the left front cylinder and a rodless cavity of the right rear cylinder respectively. The structures of the second hydraulic circuit, the third hydraulic circuit and the fourth hydraulic circuit are similar to the structure of the first hydraulic circuit. The first energy accumulator is arranged in the first hydraulic circuit. The structures of the second energy accumulator, the third energy accumulator and the fourth energy accumulator are similar to the structure of the first energy accumulator. The invention further provides a similar automobile suspension system and a motor vehicle provided with the suspension frame. The piston rod is connected with an automobile body and the hydraulic cylinder is connected with the wheel assembly.
