Abstract
The invention discloses a damper for automotive front absorbers. The damper comprises an oil storage cylinder (5) and a working cylinder (6) arranged in the oil storage cylinder (5). The oil storage cylinder (5) and the working cylinder (6) are communicated. A bottom valve component (9) is arranged at one end of the oil storage cylinder (5), and an oil seal (3) is arranged at the other end of the oil storage cylinder (5). A piston rod (2) is inserted into the working cylinder (6), a guide seat component (4), a rubber pressing sleeve (70 and a buffer spring (8) are sequentially sleeved at one end of the piston rod (2) , inserted into the working cylinder (6), the buffer spring (8) is fixed at the tail end of the piston rod (2) through a nut, and a self-locking nut (1) is arranged at the other end of the piston rod (2). By the aid of the damper in the above structure, automotive damping effect is better, and comfort and safety during running of an automotive are improved.
Description
Technical field
The present invention relates to a kind of damper, specifically be used for the damper of front absorber of automobile.
Background technique
Because being hit, elastic element produces vibrations in suspension system, for improving vehicle running smoothness, be installed in parallel vibration damper with elastic element in suspension, be the decay vibrations, adopt vibration damper to be mostly hydraulic damper in automobile suspension system, its working principle is when vibrations between vehicle frame (or vehicle body) and vehicle bridge and when relative movement occurring, the piston in vibration damper moves up and down, and the fluid in the vibration damper chamber just passes through different holes from a chamber repeatedly and flows in another chamber.Friction between hole wall and fluid and the intermolecular interior friction of fluid at this moment forms damping force to vibrations, and making the thump Conversion of Energy is fluid heat energy, then is dispersed in atmosphere by the vibration damper absorption.The fluid channel cross-section and etc. factor when constant, damping force increases and decreases with the speed of related movement between vehicle frame and vehicle bridge (or wheel), and relevant with oil viscosity.Existing vibration damper generally comprise dust cover, in connect union, external union, spring, dust-proof cover and damper, damper generally includes liquid container, clutch release slave cylinder and piston rod.When automobile ran into protruding ground in the process of moving, before vehicle front is oppressed, damping spring shrank, and when crossing the ground of projection, front damping spring resets again, and is reciprocal successively, the vibration energy that absorption and consumption Uneven road bring.Usually, damping spring has larger compression strength, after damping spring is compressed, can not allow it freely reset, otherwise resetting suddenly of damping spring will cause the secondary vibrations, and 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 complexity, can not really bring travelling comfort and Security to automobile running.
Summary of the invention
The damper that is used for front absorber of automobile provided by the present invention has solved automotive dampers damping effect in the past limited, automobile travelling comfort and the inadequate problem of Security in the process of moving.
The present invention is that the technical solution problem is achieved through the following technical solutions: the damper that is used for front absorber of automobile, comprise fuel tank and be arranged on the interior clutch release slave cylinder of fuel tank, fuel tank communicates with clutch release slave cylinder, one end of fuel tank is provided with bottom valve assembly, the other end of fuel tank is provided with oil sealing, be inserted with piston rod in clutch release slave cylinder, the end that piston rod inserts in clutch release slave cylinder is socketed with guide holder assembly, rubber gland and damping spring successively, damping spring is fixed on the end of piston rod by nut, the other end of piston rod is provided with self-locking nut.
Described oil sealing is annular element, and oil-sealing sleeve is connected on piston rod.
Described self-locking nut is hexagon nut.
Described guide holder assembly is annular element, and the guide holder assembly is socketed on piston rod, and the outer wall of guide holder assembly is fixed on the inwall of fuel tank.
The present invention compared with prior art has the following advantages and beneficial effect:
(1) the present invention is on the basis of original damper, end at piston rod is fixed with damping spring by nut, like this, the damping force that makes damper is no longer changeless, avoided resetting suddenly of damping spring to cause the secondary vibrations, make whole damping effect better, automobile travelling comfort and Security in the process of moving is better.
(2) the present invention 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 structural representation of the present invention.
In accompanying drawing, corresponding reference character is: 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
The present invention is described in further detail below in conjunction with embodiment, but embodiments of the present invention are not limited to this.
Embodiment:
As shown in Figure 1, the present invention includes fuel tank 5 and be arranged on the interior clutch release slave cylinder 6 of fuel tank 5, fuel tank 5 communicates with clutch release slave cylinder 6.
One end of the fuel tank 5 of the 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 annular element, and oil sealing 3 is socketed on piston rod 2.
Be inserted with piston rod 2 in the clutch release slave cylinder 6 of the present embodiment, the end that piston rod 2 inserts in 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 by nut, the other end of piston rod 2 is provided with self-locking nut 1, and self-locking nut 1 is hexagon nut.
The guide holder assembly 4 of the present embodiment is annular element, and guide holder assembly 4 is socketed on piston rod 2, and the outer wall of guide holder assembly 4 is fixed on the inwall of fuel tank 5.
Working principle of the present invention is: when automobile runs into the ground of projection in the process of moving, before the vehicle front compressing, damping spring shrinks, 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 the ground of projection, front 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 mentioned above, can realize well the present invention.
