Adjustable hybrid suspension damping device

Abstract

The invention relates to an adjustable mixing and suspending vibration damping device. An inner sleeve (7) opened upwards is arranged in the axial center of a vibration damping cylinder (4). An outer sleeve (1) is opened downwards. The outer sleeve (1) extends into the position between the vibration damping cylinder (4) and the inner sleeve (7) from the top end of the vibration damping cylinder (4). An upper end cover (2) and a gasket (3) are arranged at an opening of the vibration damping cylinder (4). The lower end of a push rod (11) extends into the inner sleeve (7). The upper end of the push rod (11) is in butt joint with the inner top end of the outer sleeve (1). An upper permanent magnet is fixedly connected to the lower portion of the outer sleeve (1). A lower permanent magnet is fixedly connected to the lower portion of the vibration damping cylinder (4). The upper permanent magnet and the lower permanent magnet repel each other. An upper electromagnet (9) is fixedly connected to the lower end of the push rod (11). A lower electromagnet (8) is fixedly connected to the bottom of the inner sleeve (7). The lower electromagnet (8) and the upper electromagnet (9) repel each other. Cooling fins (10) with aluminum coatings are arranged on the outer wall of the vibration damping cylinder (4). The adjustable mixing and suspending vibration damping device is long in service life, simple in structure and high in adjustability.

Description

technical field [0001] The invention relates to a vibration damping device, in particular to a magnetic suspension vibration damping device combining electromagnetic technology and permanent magnet technology. Background technique [0002] So far, the damping devices for applications and vehicles mostly use springs, hydraulic pressure, and oil-pneumatic shock absorbers to achieve the purpose of buffering and damping. These types of shock absorbers have short service life and poor maintainability, and are prone to failure after long-term use. The amount of deformation of the spring body increases with the increase of the load it receives, generally in a linear relationship, and repeated frequent deformations tend to cause it to be normal. Moreover, the expansion and contraction position of the spring shock absorber is limited, the stiffness is difficult to adjust, and its fixed damping force is difficult to adapt to different road environments; the hydraulic shock absorber r...

Problems solved by technology

Moreover, the expansion and contraction position of the spring shock absorber is limited, the stiffness is difficult to adjust, and its fixed damping force is difficult to adapt to different road environments; the hydraulic shock absorber requires extremely high airtightness, and the structure is complicated. Once oil leakage occurs, it will easily cause damage. Damping and damping failure
