Description
Technical field
The utility model relates to a kind of vibration damper, specifically is the preceding vibration damper of automobile with strong shock resistance.
Background technique
Because being hit, elastic element produces vibrations in the suspension system; For improving vehicle running smoothness, be in parallel installed with vibration damper with elastic element in the suspension, be the decay vibrations; Adopt vibration damper to be mostly hydraulic damper in the automobile suspension system; Its working principle is that the piston in the vibration damper moves up and down when relative movement occurring when vibrations between vehicle frame (or vehicle body) and vehicle bridge, and the fluid in the vibration damper chamber just flows in another chamber through different holes from a chamber times without number.The intermolecular interior friction of friction between hole wall and fluid and fluid at this moment forms damping force to vibrations, and making the thump Conversion of energy is fluid heat energy, is dispersed in the atmosphere by the vibration damper absorption again.The fluid channel cross-section with etc. factor when constant, damping force increases and decreases with the speed of related movement between vehicle frame and the vehicle bridge (or wheel), and relevant with oil viscosity.Prior oscillating damper generally comprise dust cover, in connect and join cover, external cover, spring, dust-proof cover and damper, damper generally includes liquid container, clutch release slave cylinder and piston rod.When automobile ran into the ground of convexity in the process of moving, damping spring shrank before vehicle front was oppressed, and when crossing protruding ground, preceding damping spring resets again, and is reciprocal successively, the vibration energy that absorption and consumption Uneven road bring.Usually, damping spring has bigger compression strength, after damping spring is compressed; Can not let it freely reset; Otherwise resetting suddenly causing the secondary vibrations of damping spring, this moment, damper just can be brought into play its effect, can prevent resetting suddenly of damping spring.But, the piston rod of general damping device, especially outside piston rod does not possess guiding device, when shaking when strong, is easy to cause the direction of piston rod to squint, and then influences the whole damping effect of vibration damper.
The model utility content
The utility model provides vibration damper before the automobile with strong shock resistance, solved automobile in the past when the excessive road traveling of shockproofness, and the piston rod of preceding vibration damper squints easily, and then influences the problem of damping effect.
The utility model is that the technical solution problem mainly realizes through following technological scheme: the preceding vibration damper of automobile with strong shock resistance; Comprise piston rod assembly, fuel tank assembly and be arranged on the clutch release slave cylinder assembly in the fuel tank assembly, an end of piston rod assembly is provided with gum cover, and the other end of piston rod assembly penetrates fuel tank assembly and clutch release slave cylinder assembly; And the other end of piston rod assembly is provided with Buffer Unit; The front end of said fuel tank assembly is provided with end-cap assembly, and the middle part of fuel tank assembly is fixed with supporting base, and supporting base is provided with drag hook; Drag hook is socketed in the front end of piston rod assembly, and the tail end of fuel tank assembly is provided with bottom valve assembly.
Said Buffer Unit comprises stationary axle, packing ring and nut, and nut sleeve is connected on the stationary axle.
Said bottom valve assembly comprises damping spring and beam, and damping spring is socketed on the piston rod assembly, and beam is fixed on the piston rod assembly.
Said drag hook and piston rod assembly are on same vertical plane.
The utility model compared with prior art has the following advantages and beneficial effect:
(1) on the basis of the utility model vibration damper before original; Middle part at the fuel tank assembly is fixed with supporting base; Drag hook is set on the supporting base, and drag hook is socketed in the front end of piston rod assembly, makes piston rod in movement process, can not squint; Guaranteed the conformity that receives force direction of piston rod, made the damping effect of vibration damper better.
(2) the utility model is simple in structure, and good stability is easy to operate, and practicability is stronger, is easy to popularize.

Pairing reference character is in the accompanying drawing: 1, drag hook, 2, end-cap assembly, 3, piston rod assembly, 4, the clutch release slave cylinder assembly; 5, supporting base, 6, the fuel tank assembly, 7, bottom valve assembly, 8, Buffer Unit; 9, gum cover, 10, stationary axle, 11, packing ring; 12, nut, 13, damping spring, 14, beam.
Embodiment
Below in conjunction with embodiment the utility model is done further to specify, but the mode of execution of the utility model is not limited thereto.
Embodiment:
Like Fig. 1, Fig. 2 and shown in Figure 3, the utility model comprises piston rod assembly 3, fuel tank assembly 6 and is arranged on the clutch release slave cylinder assembly 4 in the fuel tank assembly 6.
One end of the piston rod assembly 3 of present embodiment is provided with gum cover 9; The other end of piston rod assembly 3 penetrates fuel tank assembly 6 and clutch release slave cylinder assembly 4; And the other end of piston rod assembly 3 is provided with Buffer Unit 8; Buffer Unit 8 comprises stationary axle 10, packing ring 11 and nut 12, and nut 12 is socketed on the stationary axle 10.
The front end of the fuel tank assembly 6 of present embodiment is provided with end-cap assembly 2, and the middle part of fuel tank assembly 6 is fixed with supporting base 5, and supporting base 5 is provided with drag hook 1; Drag hook 1 is socketed in the front end of piston rod assembly 3; Drag hook 1 and piston rod assembly 3 are on same vertical plane, and the tail end of fuel tank assembly 6 is provided with bottom valve assembly 7, and bottom valve assembly 7 comprises damping spring 13 and beam 14; Damping spring 13 is socketed on the piston rod assembly 3, and beam 14 is fixed on the piston rod assembly 3.
The working principle of the utility model is: when automobile runs into protruding ground in the process of moving; Damping spring shrinks before the vehicle front compressing; Piston rod assembly 3 is to the direction motion near clutch release slave cylinder assembly 4, and the damping spring 11 of Buffer Unit 8 is in the state of gradually reducing, and plays buffer function; When crossing protruding ground, preceding damping spring begins to reset, and piston rod assembly 3 is to the direction motion away from clutch release slave cylinder assembly 4, and the damping spring 11 of Buffer Unit 8 is in extended state gradually, has prevented resetting suddenly of damping spring, avoids causing the secondary vibrations; Simultaneously, through the fixation of supporting base 5, drag hook 1 keeps always the direction of piston rod assembly 3, prevents skew.
As stated, then can realize the utility model well.
