Abstract
Shear -thickening damping body buffer is equipped with ram (2) for bearing the striking and blocking spring (1), spring (1) is used for reseing of piston rod (3). Piston rod (3) are furnished with double piston head (7) at the inner chamber, can improve shear -thickening's efficiency under speed in various degree. There is the free gap between cylinder body (8) and piston head (7) for guarantee the business turn over of piston rod (3). Cylinder cap (4) and cylinder body (8) are through threaded connection has O type circle (6) in, there are multiple sealed (5) with piston rod (3) cooperation department, prevent that medium (9) reveal. The utility model discloses the operating characteristic who accords with the buffer to utilize the shear -thickening characteristic of TBS liquid, form and strike the damping force, be applied to in the buffering field. The processing cost is relatively low, and is pollution -free, and safety ring protects.
Description
Technical field
This utility model relates to a kind of shearing the buffer that tackifying liquid is medium.
Background technology
In engineering reality, in metallurgy industry, in all kinds of fixed dams, railway transportation, locomotive end is crashproof and in hitch buffering, lifting industry, and the buffering of crane gear all reasonably applies buffer in actual working environment.
TBS liquid is a kind of new function material, is made up of dispersed phase particles and disperse medium, the mineral that wherein dispersed phase particles can be naturally-occurring, it is also possible to be the polymer of chemosynthesis.TBS liquid under high speed impact, apparent viscosity generation great variety, become solid phase by liquid phase even rapidly, the shock resistance of solid can be presented；Impulsive force becomes liquid phase from solid transformation rapidly again after eliminating.This shearing thickening effect is a kind of non-Newtonian fluid behavior, reversible during its change.According to this characteristic, can being applied to shock resistance field, at present in the preparation of bullet resistant material or other preventers, be widely used, this material also has good prospect in field of shock absorption simultaneously.TBS liquid can provide anti-impact force, owing to shearing the reversibility of thickening so that it is can recycle and can effectively form Anti-impact shock-absorbing.
Characteristic according to buffer, it is desirable to the kinetic energy of buffering mobile object, utilizes the damping force of medium to be converted into heat energy and potential energy, reduces Percussion counter-force, and can automatically reset, reuse.The viscosity building characteristic of shearing that can adopt TBS liquid goes to realize the characteristic principle that in impact process, damping force increases, and relatively normal hydraulic oil better converts kinetic energy is heat energy, makes buffering effect better.
Utility model content
In order to make buffer better effects if, reducing cost, carrying under high efficiency premise, this shearing thickening damping body buffer adopts and plays the characteristic shearing thickening of high-tech liquid TBS, for needing the position of buffering, the buffer products of design specialized.This product cost is low, pollution-free, and the life-span is long, and effect is notable.
Concrete structure design is as follows；
Shearing thickening damping body buffer equipped with ram (2), be used for bearing shock and blocking spring (1), spring (1) stretches along with the movement of piston rod (3), for the reset of piston rod (3).Piston rod (3) is furnished with double piston head (7) at inner chamber, it is possible to improve the efficiency shearing thickening under speed in various degree.There is free gap between cylinder body (8) and piston head (7), be used for ensureing the turnover of piston rod (3).Cylinder cap (4) and cylinder body (8) are threaded connection becomes a sealing entirety, inside has O (6)；Multi-sealed (5) are had, it is prevented that medium (9) is revealed with piston rod (3) place of cooperation.
Owing to have employed technique scheme and TBS liquid, this utility model has the following advantages and effect:
1. this utility model meets the operating characteristic of buffer, and utilizes the shearing viscosity building characteristic of TBS liquid, forms impact damping power, is applied in buffering field, more can embody the advantage of above-mentioned utility model.
2. significantly reduce production cost, the shearing viscosity building characteristic reaction of TBS liquid is very sensitive, adopt in shellproof equipment development at present, so applying on buffer, it is not required to the excessively precision that piston rod coordinates with cylinder body, leaving very big space and cavity and can pass through liquid, greatly reducing difficulty of processing, thus reducing cost.
3. this utility model reasonable in design, safeguards simple, without external equipment, stable and reliable for performance, pollution-free.
Accompanying drawing explanation
Fig. 1 is the overall cross-sectional schematic of this utility model structure
In figure: spring (1), ram (2), piston rod (3), cylinder cap (4), seals (5), O (6), piston head (7), cylinder body (8), medium (9).
Detailed description of the invention
As shown in Figure 1: piston head has different size of hole on (7), it was used for liquid to use.During impact, piston rod (3) quickly enters cylinder body (8) the medium (9) shearing in cylinder body (8) with piston head (7), the fluid force of medium (9) increases, " particle race ' become big; the inhibition of medium (9) fluid is also become big; therefore the viscosity of medium (9) fluid increases; produce huge resistance; form damping; slow down impact velocity, impact kinetic energy is converted into heat energy release, thus playing cushioning effect.After impact completes, piston rod (3) resets under the effect of spring (1), prepares to impact next time.
Claims (1)
1. shear thickening damping body buffer for one kind, its practical new structure is: threaded with cylinder body (8) that to become a sealing overall equipped with sealing the cylinder cap (4) of (5) and O (6), piston rod (3) is furnished with double piston head (7), together it is placed in cylinder body (8) with medium (9), spring (1) ramed (2) block, it is characterised in that: spring (1) stretches along with the movement of piston rod (3).
