Abstract

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.

Description

technical field [0001] The invention relates to the technical field of vehicle suspension, in particular to a vehicle suspension using an inertial mass accumulator. Background technique [0002] The function of the suspension is mainly to ensure good ride comfort and stable tire load. In addition, the suspension must also control the suspension travel within the allowable range while performing this function. The traditional passive suspension is composed of springs and dampers. On the one hand, using soft springs can obtain better ride comfort, but on the other hand, high ride comfort is always at the expense of the suspension working space. At the same time It will also have an adverse effect on driving safety. This contradiction is a difficult problem faced by suspension designers. [0003] Chinese patent 200810123830.8 discloses a vehicle suspension using an inertial accumulator, including a parallel body composed of an inertial mass accumulator and a damper, and a para...
