Description
Technical field
A kind of Multistage damping device is the utility model is related to, belongs to technical field of automobile accessories.
Background technology
Damping is exactly an energy conversion device in fact, and its operation principle is exactly that external work is first converted into bullet
Property potential energy, then consumes elastic potential energy by the compression valve rod and damper cylinder frictional heat of damper, what last external force was done
Work(is just converted into heat energy dissipation, and here it is the effect of damper.Conventional base device does not simply fail to realize in shock absorbing process
Comprehensive effective damping, can also produce unnecessary impulsive force, vehicle body is damaged, and uncomfortable body by bus is brought to passenger
Test.
The content of the invention
The purpose of this utility model is to provide a kind of Multistage damping device, can not be supported with solving the unnecessary impulsive force of offroad vehicle
The problem of disappearing and weakening.
The utility model adopts the following technical scheme that：A kind of Multistage damping device includes upper lift ring 1, compression valve rod 2, pair and subtracted
Shake spring 7, damper cylinder 8, main damping spring 9, base 10；The upper lift ring 1 is connected with compression valve rod 2, compression valve rod 2 and damping
Cylinder 8 is connected, and damper cylinder 8 is fixed on base 10, and compression valve rod 2 can be flexible up and down in damper cylinder 8；It is arranged on compression valve rod 2
There is secondary damping spring 7, main damping spring 9 is arranged with damper cylinder 8, by the flexible of main damping spring 9, aid in the He of damper cylinder 8
Compression valve rod 2 realizes secondary shock-absorbing；Side damping spring group is provided between the upper end of compression valve rod 2 and the upper end of damper cylinder 8.
Connected between the damper cylinder 8 and compression valve rod 2 for piston.Damper cylinder 8 and the combination of compression valve rod 2 are lived by oil pump
The mutual friction of plug phase weakens or offset most of foreign impacts power,
Described side damping spring group one end is fixed on compression valve rod 2 and the junction of upper lift ring 1, and one end is fixed on damper cylinder 8
Upper surface.
The side damping spring group includes side damping spring I 3, side damping spring II 4, side damping spring III 5 and side damping
Spring IV 6, four are evenly distributed on the surrounding of compression valve rod 2.By the flexible of secondary damping spring 7, weaken main damping and fail to offset
Impulsive force, the side damping spring of surrounding weakens or offsets the impulsive force from surrounding.
The course of work of the present utility model：When damping device is by foreign impacts power, compression valve rod is compressed to damper cylinder
Interior, main damping spring is in compressive state, and secondary damping spring is in extended state, because compression valve rod compresses downwards, generates
Unnecessary impulsive force, the side damping spring group extended state of surrounding；In extraneous impulsive force basic neutralisation, compression valve rod returns to original
Position, main damping spring are in extended state, and secondary damping spring is in compressive state, and the side damping spring group of surrounding returns to contraction
State；Damping device realizes effective damping effect by mutually filling to change between the two states.
The utility model has the advantages that：
This damping device is detachable, is conveniently replaceable part；Damping effect is strong, suitable for modern all kinds of offroad vehicles, realizes
Comprehensive damping, more effectively protects vehicle body.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
In figure respectively marked as：1- upper lift rings, 2- compression valve rods, 3- sides damping spring I, 4- sides damping spring II, 5- sides subtract
Shake spring III, 6- sides damping spring IV, 7- pairs damping spring, 8- damper cylinders, the main damping springs of 9-, 10- bases.
Embodiment
With reference to the accompanying drawings and examples, the utility model is described in further detail, but content of the present utility model is not
It is limited to the scope.
Embodiment 1：As shown in figure 1, a kind of Multistage damping device include upper lift ring 1, compression valve rod 2, secondary damping spring 7,
Damper cylinder 8, main damping spring 9, base 10；The upper lift ring 1 is connected with compression valve rod 2, and compression valve rod 2 is connected with damper cylinder 8,
Damper cylinder 8 is fixed on base 10, and compression valve rod 2 can be flexible up and down in damper cylinder 8；Secondary damping is arranged with compression valve rod 2
Spring 7, main damping spring 9 is arranged with damper cylinder 8, pass through the flexible of main damping spring 9, aid in damper cylinder 8 and compression valve rod 2
Realize secondary shock-absorbing；Side damping spring group is provided between the upper end of compression valve rod 2 and the upper end of damper cylinder 8.The damper cylinder 8 and pressure
Connected between contracting valve rod 2 for piston.Damper cylinder 8 and the combination of compression valve rod 2 are weakened by the mutual friction of oil pump piston phase or offset big
Part foreign impacts power.
Embodiment 2：The present embodiment is identical with remainder with previous embodiment, wherein described side damping spring group one end is consolidated
Compression valve rod 2 and the junction of upper lift ring 1 are scheduled on, one end is fixed on the upper surface of damper cylinder 8.The side damping spring group includes side
Damping spring I 3, side damping spring II 4, side damping spring III 5 and side damping spring IV 6, four are evenly distributed on compression valve rod 2
Surrounding.By the flexible of secondary damping spring 7, weaken the impulsive force that main damping fails to offset, the side damping spring of surrounding weaken or
Offset the impulsive force from surrounding.
When damping device is by foreign impacts power, compression valve rod 2 is compressed in damper cylinder 8, is sleeved on damper cylinder 8
Main damping spring 9 is in compressive state, and the secondary damping spring 7 on compression valve rod 2 is in extended state, because compression valve rod is downward
Compression, generates unnecessary impulsive force, the side damping spring I 3 of surrounding, side damping spring II 4, side damping spring III 5, side damping
Spring IV 6 is in extended state；In extraneous impulsive force basic neutralisation, compression valve rod 2 returns to original position, is sleeved on damper cylinder 8
On main damping spring 9 be in extended state, the secondary damping spring 7 on compression valve rod 2 is in compressive state, the side damping of surrounding
Spring I 3, side damping spring II 4, side damping spring III 5, side damping spring IV 6 return to contraction state；Damping device passes through at this
Mutually dress changes and realizes effective damping effect between two states.
Specific embodiment of the present utility model is explained in detail above in conjunction with figure, but the utility model and unlimited
In above-mentioned embodiment, in those of ordinary skill in the art's possessed knowledge, this practicality can also not departed from newly
Various changes can be made on the premise of type objective.
