Abstract
The invention discloses a stable-type damping device, which comprises at least two magnets. Opposite magnetic poles of the magnets are adjacent, the magnets are hinged on a cross shear-type expansion bracket, retaining-and-guiding inner sleeves are sleeved outside the magnets, upper end seats and lower end seats are disposed at both ends of the retaining-and-guiding inner sleeves respectively andconnected with both ends of the cross shear-type expansion frame respectively, and damping springs are installed between the upper end seats and the lower end seats. Since opposite magnetic poles of adjacent magnets are arranged oppositely, the closer the distance, the greater the attraction; when severe vibration occurs, the damping springs are compressed and deformed greatly, the elasticity of the damping springs increases linearly with the deformation; when the deformation of the damping springs increases, the distance between adjacent magnets decreases, the attraction increases geometrically, a part of increased elasticity is offset, in other words, impact force to car frames is decreased. By the stable-type damping device, stable damping can be realized when the elasticity of damperscan be kept changing mildly and nonlinearly within a bigger deformation range.

Embodiment
Below in conjunction with drawings and Examples, further set forth the present invention.In the following detailed description, only by the mode of explanation some one exemplary embodiment of the present invention has been described.Undoubtedly, those of ordinary skill in the art can recognize, under situation without departing from the spirit and scope of the present invention, can revise described embodiment with various mode.Therefore, accompanying drawing is illustrative with being described in essence, rather than is used for the protection domain of restriction claim.
Embodiment one:
As shown in Figure 1, the stable type damping device, comprise five blocks of magnet 2 that opposite pole is relative, described magnet 2 is hinged on the intersection scissors expansion bracket 1, as shown in Figure 2, described magnet 2 is provided with expansion bracket active tunnel 21, is provided with the expansion bracket hinging shaft 22 of fixedlying connected with described magnet 2 in the described expansion bracket active tunnel 21, and described intersection scissors expansion bracket 1 and described expansion bracket hinging shaft 22 are hinged.The outside of described magnet 2 is set with spacing guiding inner sleeve 3, middle described magnet 2 is fixedlyed connected with described spacing guiding inner sleeve 3, leave the gap of 0.1mm to 0.8mm between all the other magnet 2 and the described spacing guiding inner sleeve 3, when magnet 2 moves in spacing guiding inner sleeve 3 like this, can not interfere with the inwall of spacing guiding inner sleeve 3, can improve the working life of spacing guiding inner sleeve 3 and magnet 2; The two ends of described spacing guiding inner sleeve 3 are separately installed with upper end base and lower end seat, described upper end base comprises upper end cap 41, an end face of described upper end cap 41 is provided with the outer sleeve 42 that leads of going up that is sleeved on described spacing guiding inner sleeve 3 upper end portions, and the described internal diameter of guiding outer sleeve 42 of going up is greater than the external diameter of described spacing guiding inner sleeve 3; Another end face of described upper end cap 41 is provided with installs hanger 43; Described lower end seat comprises lower end cap 51, and an end face of described lower end cap 51 is provided with the following guiding outer sleeve 52 that is sleeved on described spacing guiding inner sleeve 3 underparts, and the internal diameter of the described outer sleeve 52 of guiding down is greater than the external diameter of described spacing guiding inner sleeve 3; Another end face of described lower end cap 51 is provided with down installs hanger 53; Described upper end cap 41 is connected by upper connecting rod 6 with described scissors expansion bracket 1 upper end that intersects, and described lower end cap 51 is connected by lower connecting rod 7 with described scissors expansion bracket 1 lower end that intersects.Between described upper end cap 41 and the described lower end cap 51 damping spring 8 is installed, described damping spring 8 is sleeved on described guiding outer sleeve 42 and the described outside of guiding outer sleeve 52 down of going up, and fixedlys connected with described lower end cap 51 with described upper end cap 41 respectively in the two ends of described damping spring 8.Described bottom of going up guiding outer sleeve 42 is provided with the last cushion rubber bumper 44 that can avoid fierce collision, and the described bottom of guiding outer sleeve 52 down is provided with the following cushion rubber bumper 54 that can avoid fierce collision.
Working principle: because adjacent magnets 2 is that opposite pole is relative, distance is more near, attraction force is more big, and when strenuous vibration occurring, damping spring 8 compressed deformation are also bigger, its elastic force conformal modified line increase, along with damping spring 8 deformation strengthen, the distance between the adjacent magnets 2 reduces, and attraction force increases by geometrical progression, offset the elastic force of a part of increase, also namely reduced the impact force to vehicle frame.Therefore, make the elastic force of vibration damper in than the large deformation scope, keep soft nonlinear change, reach the purpose of stablizing damping, improve comfortable feel; That the present invention not only can reach is safe, practical, environmental protection and purpose of energy saving, can also realize the damping effect of stability and high efficiency.
