Embodiment 2
[0045] The novel inertial element device that is used for automobile suspension described in embodiment 1 is added in traditional " spring-damper " suspension, obtains new " inertial element-spring-damper " suspension structure, as image 3 As shown, the inertial element 15, spring 14 and damper 16 are directly connected in parallel, and then the parallel structure of the spring 14 and damper 16 is connected in series. The reason for this design is that the traditional suspension system composed of spring and damper can filter high frequency vibration, and the system of springs, inertial elements and damping can filter low-frequency vibrations; therefore, when the two systems are connected in series, they can isolate both low-frequency vibrations and high-frequency vibrations, improving the comfort of the car and handling stability. The dynamic characteristics of the new suspension structure are obtained after Matlab simulation and calculation. The frequency response character...

The invention relates to an inertia container device, in particular to a novel inertia element device for an automobile suspension frame. The novel inertia element device comprises a screw rod, wherein two ends of the screw rod are of smooth structures, the middle part of the screw rod is provided with a threaded rolling way, the end part of one end of the screw rod is provided with a lifting lug A, the threaded rolling way of the screw rod stretches to the inner part of a stroke chamber shell, the end surface of one end of the stroke chamber shell is fixedly provided with an end cover, the end surface of the other end of the stroke chamber shell is provided with a lifting lug B, the stroke chamber shell is internally and fixedly provided with a ball screw pair, the ball screw pair comprises the threaded rolling way, a nut A, a nut gasket and a nut B, balls are arranged between the nut A and the threaded rolling way as well as between the nut B and the threaded rolling way, the nut gasket is arranged between the nut A and the nut B, a bearing A and a bearing B are respectively arranged at the peripheries of the nut A and the nut B and are in contact with the inner wall of the stroke chamber shell, a through hole is formed in the center of the end cover, and the nut A is used for fixing a flywheel as one end of the nut A penetrates through the through hole. The novel inertia element device disclosed by the invention has the advantages that the motion friction force is small, the ball screw assembly is adopted, and the problems of phase lag, impact and noise are removed through carrying out pre-tightening compensation on a gap of the ball screw pair.
Description
technical field [0001] The invention relates to an inertial container device, in particular to a novel inertial element device used for automobile suspension. Background technique [0002] In the process of driving a car, car ride comfort and handling stability are two very critical performances that are directly felt by drivers and passengers, and suspension, as one of the core components of the chassis, profoundly affects the car ride comfort and handling stability sex. At present, the development of suspension technology is relatively mature, but there are still some problems. [0003] Traditional suspensions are mainly passive suspensions. Although there are various structural forms of various suspensions, damping elements, elastic elements and guiding mechanisms are the three main components of suspensions. This kind of traditional suspension is relatively reliable, with fixed spring stiffness and shock absorber damping, but this kind of suspension vehicle ride comfor...
