Abstract
The utility model discloses a damper for a front absorber of an automobile. The damper comprises an oil storage drum (5) and a working cylinder (6) arranged in the oil storage drum (5), wherein the oil storage drum (5) is communicated with the working cylinder (6); one end of the oil storage drum (5) is provided with a bottom valve assembly (9), and the other end of the oil storage drum (5) is provided with an oil seal (3); a piston rod (2) is inserted in the working cylinder (6), and one end of the piston rod (2) inserted in the working cylinder (6) is successively sleeved with a guide holder assembly (4), a rubber pressing sleeve (7) and a buffer spring (8); and the buffer spring (8) is fixed on the tail end of the piston rod (2) through a nut, and the other end of the piston rod (2) is provided with a self-locking nut (1). The damper provided by the utility model adopts the structure above, the shock absorption effect of the automobile is better, and the comfortability and the security are improved when the automobile is in a travelling process.
Description
Technical field
The utility model relates to a kind of damper, specifically is the damper that is used for the preceding vibration damper of automobile.
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 damping force of general damping device is fixed, and the reset speed of spring is also fixed, so damping effect is limited, so just can not tackle the road shape of various complicacies, can not really bring travelling comfort and Security to automobile running.
The model utility content
The utility model provides the damper that is used for the preceding vibration damper of automobile, and it is limited to have solved automotive dampers damping effect in the past, automobile travelling comfort and the not enough problem of Security in the process of moving.
The utility model is that the technical solution problem mainly realizes through following technological scheme: the damper that is used for the preceding vibration damper of automobile; Comprise fuel tank and be arranged on the clutch release slave cylinder in the fuel tank; Fuel tank communicates with clutch release slave cylinder, and an end of fuel tank is provided with bottom valve assembly, and the other end of fuel tank is provided with oil sealing; Be inserted with piston rod in the clutch release slave cylinder; The end that piston rod inserts in the clutch release slave cylinder is socketed with guide holder assembly, rubber gland and damping spring successively, and damping spring is fixed on the end of piston rod through nut, and the other end of piston rod is provided with self-locking nut.
Said oil sealing is an annular element, and oil-sealing sleeve is connected on the piston rod.
Said self-locking nut is a hexagon nut.
Said guide holder assembly is an annular element, and the guide holder assembly is socketed on the piston rod, and the outer wall of guide holder assembly is fixed on the inwall of fuel tank.
The utility model compared with prior art has the following advantages and beneficial effect:
(1) the utility model is on the basis of original damper; End at piston rod is fixed with damping spring through nut; Like this, make that the damping force of damper no longer is changeless, avoided resetting suddenly of damping spring to cause the secondary vibrations; Make that whole damping effect is better, automobile travelling comfort and Security in the process of moving is better.
(2) the utility model is simple in structure, and good stability is easy to operate, and practicability is stronger, is easy to popularize.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Pairing reference character is in the accompanying drawing: 1, self-locking nut, 2, piston rod, 3, oil sealing, 4, the guide holder assembly, 5, fuel tank, 6, clutch release slave cylinder, 7, the rubber gland, 8, damping spring, 9, bottom valve assembly.
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:
As shown in Figure 1, the utility model comprises fuel tank 5 and is arranged on the clutch release slave cylinder 6 in the fuel tank 5 that fuel tank 5 communicates with clutch release slave cylinder 6.
One end of the fuel tank 5 of present embodiment is provided with bottom valve assembly 9, and the other end of fuel tank 5 is provided with oil sealing 3, and oil sealing 3 is an annular element, and oil sealing 3 is socketed on the piston rod 2.
Be inserted with piston rod 2 in the clutch release slave cylinder 6 of present embodiment; The end that piston rod 2 inserts in the clutch release slave cylinder 6 is socketed with guide holder assembly 4, rubber gland 7 and damping spring 8 successively; Damping spring 8 is fixed on the end of piston rod 2 through nut; The other end of piston rod 2 is provided with self-locking nut 1, and self-locking nut 1 is a hexagon nut.
The guide holder assembly 4 of present embodiment is an annular element, and guide holder assembly 4 is socketed on the piston rod 2, and the outer wall of guide holder assembly 4 is fixed on the inwall of fuel tank 5.
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; The piston rod 2 of damper is to the direction motion near clutch release slave cylinder 6, and damping spring 8 is in the state of gradually reducing, and plays buffer function; When crossing protruding ground, preceding damping spring begins to reset, and the piston rod 2 of damper is to the direction motion away from clutch release slave cylinder 6, and damping spring 8 is in extended state gradually, has prevented resetting suddenly of damping spring, avoids causing the secondary vibrations.
As stated, then can realize the utility model well.
