Abstract
The utility model discloses a shock absorber vibration damper, which comprises an outer cylinder, an inner cylinder, upper and lower floating pistons, upper and lower elastic elements and a piston with rod. The inner cylinder is arranged in the outer cylinder, which forms a fluid infusion cavity with the outer cylinder; the upper floating piston is arranged in the upper part of the outer cylinder; the lower floating piston is arranged in the inner cylinder; the upper elastic element is arranged between the top of the outer cylinder and the upper floating piston; the lower elastic element is arranged between the bottom of the cylinder and the lower floating piston; the piston with rod is arranged between the upper and the lower floating pistons to form upper and lower vibration damping cavities which has positive and reverse vibration damping valves which are communicated with the upper and the lower vibration damping cavities; a fluid infusion valve is arranged between the fluid infusion cavity and the upper vibration damping cavity. The shock absorber vibration damper can change the stiffness of vehicle suspension systems and other vibrating damping systems, and simultaneously has the functions of shock absorber and vibration damper.
Description
The utility model belongs to the parts of vehicle suspension system and other vibration systems, particularly a kind of shock damper.
In existing vehicle suspension system and other vibration systems, adopt shock-absorbings such as leaf spring, torsion bar and gas spring usually, adopt cartridge type or rocking arm type hydraulic shock absorber vibration damping.This vibration damper has only the individual event vibration-damping function, make vehicle suspension system under different operating modes, remain the rigidity that depends on the shock absorber original design with other vibration systems, this rigidity make vehicle etc. when different operating mode or vibration attenuation slow, or rigid impact increases, not only make and improve the speed of a motor vehicle and be restricted, and make the occupant uncomfortable and influence working life of vehicle.
The purpose of this utility model provide a kind of when different operating mode, can change vehicle suspension system and other vibration system rigidity, and have the shock damper of shock-absorbing, vibration-damping function simultaneously.
The utlity model has outer shell, inner casing, upper and lower floating piston, upper and lower elastic element and piston with rod.Inner casing places in the outer shell and is positioned at the bottom, and and outer shell between constitute the fluid infusion chamber; Last floating piston places in the outer shell and is positioned at top; Following floating piston places in the inner casing; Last elastic element places in the outer shell and between outer shell top and last floating piston; Following elastic element places in the inner casing and between cylinder bottom and following floating piston; Piston with rod places in the inner casing and between upper and lower floating piston, and and the upper and lower vibration damping of formation chamber between the upper and lower floating piston, have the forward and reverse damper valve that communicates with upper and lower vibration damping chamber on the piston of piston with rod, have make-up valve between fluid infusion chamber and the last vibration damping chamber.
Owing to have outer shell, inner casing, upper and lower floating piston, upper and lower elastic element and piston with rod.Inner casing places in the outer shell and is positioned at the bottom, and and outer shell between constitute the fluid infusion chamber; Last floating piston places in the outer shell and is positioned at top; Following floating piston places in the inner casing; Last elastic element places in the outer shell and between outer shell top and last floating piston; Following elastic element places in the inner casing and between cylinder bottom and following floating piston; Piston with rod places in the inner casing and between upper and lower floating piston, and and the upper and lower vibration damping of formation chamber between the upper and lower floating piston, have the forward and reverse damper valve that communicates with upper and lower vibration damping chamber on the piston of piston with rod, have make-up valve between fluid infusion chamber and the last vibration damping chamber.Under nominal situation, piston rod is made upwards working stroke under positive outward force effect, forward damper valve on the rod end piston is opened, and makes vibration damping chamber inner fluid flow into vibration damping chamber down fast, when piston stroke is extremely terminal, move on the floating piston in the promotion, elastic element in the compression, impedance cushions external force and plays the shock-absorbing effect, behind the last elastic element pressurized, last vibration damping chamber volume increases, and the fluid in the fluid infusion chamber enters the vibration damping chamber fast through make-up valve; After upwards the external force of working stroke disappears, restore under the elastic force effect at last elastic element, last floating piston moves down, fluid pressurized in the last vibration damping chamber, get back to the fluid infusion chamber at a slow speed through make-up valve, when last elastic element returns to reset condition, piston rod restores the elastic force effect when continuing to move down at shock absorber, following vibration damping chamber inner fluid enters the vibration damping chamber through reverse damper valve, plays damping effect.
When piston in opposite force effect following time, oppositely the damper valve working procedure is identical, the working stroke direction is opposite, the utility model plays the shock-absorbing damping effect on opposite direction.
In the fierce external force effect operating mode of impacting, piston with rod is when making up and down stroke, be compressed end vibration damping chamber inner fluid since can not be in time by corresponding damper valve fast outflow cause in this vibration damping chamber oil pressure moment and increase the elastic element that compresses respective end, make elastic element participate in impedance buffering external force in advance, play the shock-absorbing effect with shock absorber, improved the rigidity of vehicle suspension system and other vibration systems.Thereby reach the purpose of this utility model.
Fig. 1 is the utility model structural representation sectional drawing.
Below in conjunction with accompanying drawing the utility model is further elaborated.
The utlity model has outer shell 1, inner casing 2, upper and lower floating piston 3,4, upper and lower elastic element 5,6 and piston with rod 7.Inner casing 2 places in the outer shell 1 and is positioned at the bottom, and and outer shell 1 between constitute fluid infusion chamber 8; Last floating piston 3 places in the outer shell 1 and is positioned at top; Following floating piston 4 places in the inner casing 2; Upper and lower elastic element 5,6 is single step helical spring or hard elastic material or inert gas, also can be multiple coil spring or hard elastic material or inert gas, and last elastic element 5 places in the outer shell 1 and between outer shell top and last floating piston 3; Following elastic element 6 places in the inner casing 2 and between interior cylinder bottom and following floating piston 4; Piston with rod 7 places in the inner casing 2 and between upper and lower floating piston 3,4, and and the upper and lower vibration damping of formation chamber 9,10 between the upper and lower floating piston 3,4, have the forward and reverse damper valve 11,12 that communicates with upper and lower vibration damping chamber 9,10 on the piston 71 of piston with rod 7, have make-up valve 13 between fluid infusion chamber 8 and the last vibration damping chamber 9.
