The invention discloses an inertial mass energy-accumulation type vehicle suspension, relating to the technical field of vehicle suspensions. The inertia mass energy storage type vehicle suspension is characterized by comprising a vehicle vibration isolator (1) and a wheel vibration isolator (2), wherein the vehicle body vibration isolator (1) comprises a spring A (3), a damper A (4) and an inertial mass energy accumulator (5), the spring A (3), the damper A (4) and the inertial mass energy accumulator (5) are connected in parallel; the wheel vibration isolator (2) comprises a spring B (6) and a damper B (7), and the spring B (6) and the damper B (7) are connected in parallel; and the vehicle body vibration isolator (1) and the wheel vibration isolator (2) are connected in series. The invention not only greatly improves the sitting comfortableness of vehicles, but also improves the driving safety and greatly promotes the overall properties of the suspension. The invention has the advantages of compact structure, small occupying area, easy arrangement, low cost, high reliability, and no needs of complicated controllers, control strategies, electronic elements and energy input.
