Abstract
The invention discloses a damper for damping vehicle vibration. The damper comprises an oil storing cylinder (1), a working cylinder (4) and a piston rod (11). The working cylinder (4) is positioned in the oil storing cylinder (1), and the piston (11) extends into the working cylinder (4). A buffer spring (6), a guide holder assembly (7), an oil seal (8) and a top cover (10) are respectively sleeved on the piston rod (11). A bottom valve assembly (2) is sleeved at the extending end of the piston rod (11) in the working cylinder (4). Shock pads (5) sleeved on the piston rod (11) are respectively arranged at two ends of the buffer spring (6). By adopting the structure, the damper has a better vibration damping effect, and enables a vehicle to be more stable in driving.
Description
Technical field
The present invention relates to a kind of damper, specifically a kind of damper for attenuating automobile vibration.
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.But general damper can only be accomplished vibration attenuation roughly, does not reach more satisfactory vibration attenuation, causes automobile smoothness in the process of moving inadequate.
Summary of the invention
A kind of damper for attenuating automobile vibration provided by the present invention has solved automotive dampers vibration attenuation in the past undesirable, causes the inadequate problem of automobile stationarity in the process of moving.
The present invention is that the technical solution problem is achieved through the following technical solutions: a kind of damper for attenuating automobile vibration, comprise fuel tank, clutch release slave cylinder and piston rod, clutch release slave cylinder is positioned at fuel tank, piston rod stretches in clutch release slave cylinder, be socketed with successively damping spring, guide holder assembly, oil sealing and top cover on piston rod, the end that described piston rod stretches into clutch release slave cylinder is socketed with bottom valve assembly, and the two ends of damping spring are provided with the beam that is socketed on piston rod.
Described oil sealing is provided with the sealing packing ring that is socketed on piston rod.
Described bottom valve assembly is provided with the positioning ring that is socketed on piston rod.
Described top cover also is socketed on fuel tank.
The present invention compared with prior art has the following advantages and beneficial effect:
(1) the present invention is provided with damping spring and beam in the clutch release slave cylinder of original damper, makes cushioning effect better; Be provided with the guide holder assembly in fuel tank simultaneously, make the operation of piston rod more steady.
(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, fuel tank, 2, bottom valve assembly, 3, positioning ring, 4, clutch release slave cylinder, 5, antifriction pad, 6, damping spring, 7, the guide holder assembly, 8, oil sealing, 9, the sealing packing ring, 10, top cover, 11, piston rod.
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 1, clutch release slave cylinder 4 and piston rod 11, clutch release slave cylinder 4 is positioned at fuel tank 1, and piston rod 11 stretches in clutch release slave cylinder 4.
Be socketed with successively damping spring 6, guide holder assembly 7, oil sealing 8 and top cover 10 on the piston rod 11 of the present embodiment, the end that piston rod 11 stretches into clutch release slave cylinder 4 is socketed with bottom valve assembly 2.
The two ends of the damping spring 6 of the present embodiment are provided with the beam 5 that is socketed on piston rod 11.
The oil sealing 8 of the present embodiment is provided with the sealing packing ring 9 that is socketed on piston rod 11.
The bottom valve assembly 2 of the present embodiment is provided with the positioning ring 3 that is socketed on piston rod 11.
Working principle of the present invention is: when wheel shifts near vehicle body, vehicle shock absorber by compression, the piston rod 11 of damper moves downward, damping spring 6 also is in compressive state, weakens the vibration of automobile, slows down the change in displacement speed between wheel and vehicle body; During away from vehicle body, vehicle shock absorber is in extended state when wheel, and the piston rod 11 of damper moves upward, and damping spring 6 also is in extended state, slows down equally the change in displacement speed between wheel and vehicle body.
As mentioned above, can realize well the present invention.
