Abstract
The utility model relates to the technical field of damping devices of automobiles, and in particular relates to a mechanical thread-regulating damping mechanism. The mechanical thread-regulating damping mechanism comprises an upper regulating knob assembly, a piston rod and a lower regulating knob assembly, wherein the upper regulating knob assembly is arranged at the upper part of the piston rod, the lower regulating knob assembly is arranged at the lower part of the piston rod, and a thread regulating rod is arranged in an axial through hole of the piston rod. The damping force is controlled through the up and down sliding of the thread regulating rod, thus the mechanical thread-regulating damping mechanism has the advantages of simple structure, high precision, long service life and good compatibility, and avoids generating a problem of sudden starting or stopping when the flow rate of oil is regulated.
Description
Technical field
The utility model relates to the automobile shock-absorber technical field, especially a kind of mechanical type threaded adjusting damping mechanism.
Background technique
In the suspension system of automobile, produce vibration because elastic element is hit, for improving vehicle running smoothness, be in parallel installed with vibration damper with elastic element in the suspension, with attenuation vibration, mostly the vibration damper that adopts in the automobile suspension system is dydraulic shock absorber.Its working principle is through fluid pressure in rotation adjusted knob assembly and the damper sliding device to be moved to regulating the opening and closing of knob shaft to opening down, thereby damping force is reduced and increases.Since regulate down knob shaft to opening open deattenuation the time, must sliding device be moved by fluid pressure in circle round counterclockwise adjusted knob assembly and the damper.
When regulating its fluid flow, can produce and hold suddenly or the phenomenon of all standing, be applied in the suspension system of automobile; Can make the smoothness of automobile and control stability to become relatively poor, and make its stopping distance elongated, sideway skid resistance is poor; And damp adjustable range is little, regulates damping force value inaccuracy; Sliding device split structure compatible property is poor, and working life is shorter.
The model utility content
In order to overcome the prior oscillating damper poor stability, stopping distance is long, and regulation range is little, the deficiency that the life-span is short, and the utility model provides a kind of mechanical type threaded adjusting damping mechanism.
The utility model solves the technological scheme that its technical problem adopted: a kind of mechanical type threaded adjusting damping mechanism; Comprise adjusted knob assembly, piston rod and regulate knob assembly down; The adjusted knob assembly is positioned at piston rod top; Under regulate knob assembly and be positioned at underpart of the piston rod, be provided with the threaded adjusting bar in the axial hole of piston rod.
According to another embodiment of the utility model, comprise that further an end of threaded adjusting bar is connected with the adjusted knob assembly through screw.
According to another embodiment of the utility model, comprise that further threaded adjusting bar and piston rod are slidingly connected.
According to another embodiment of the utility model, comprise that further the threaded adjusting bar is provided with seal ring.
The beneficial effect of the utility model is, utilizes sliding up and down of threaded adjusting bar to control the size of damping force, and is simple in structure, validity is high, and working life is long, better compatible, when it regulates its fluid flow, avoided producing and opened suddenly or the problem of all standing.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model.
1. adjusted knob assemblies among the figure, 2. piston rod, 3. time adjusting knob assembly, 4. threaded adjusting bar, 5. seal ring.
Embodiment
Like Fig. 1 is the structural representation of the utility model; A kind of mechanical type threaded adjusting damping mechanism; Comprise adjusted knob assembly 1, piston rod 2 and regulate knob assembly 3 down; Adjusted knob assembly 1 is positioned at piston rod 2 tops, and following adjusting knob assembly 3 is positioned at piston rod 2 bottoms, is provided with threaded adjusting bar 4 in the axial hole of piston rod 2.One end of threaded adjusting bar 4 is connected with adjusted knob assembly 1 through screw.Threaded adjusting bar 4 is slidingly connected with piston rod 2.Threaded adjusting bar 4 is provided with seal ring 5.
This mechanical type threaded adjusting damping mechanism working principle is to drive threaded adjusting bar 4 through rotation adjusted knob assembly 1 in the axial hole of piston rod 2, to move up and down; Opening or closing of axial flow through hole on the knob assembly 3 regulated down in control, thereby damping force is reduced or increases.During 1 dextrorotation of adjusted knob assembly, drive the 4 downward end motions of threaded adjusting bar, stop up and regulate the axial flow through hole on the knob assembly 3 down; Thereby play the effect of damming, make damping value increase amplification >=20%; When otherwise adjusted knob assembly 1 is left-handed, drive the 4 upwards end motions of threaded adjusting bar, open down the axial flow through hole on the adjusting knob assembly 3; The effect of damming reduces, and damping value is reduced, amount of decrease >=20%.
Utilize sliding up and down of threaded adjusting bar 4 to control the size of damping force, simple in structure, validity is high, working life is long, better compatible, when it regulates its fluid flow, has avoided producing and has opened suddenly or the problem of all standing.
