Abstract

The utility model discloses a damper for attenuating the automobile vibration, which comprises an oil storage tank (1), a working cylinder (4) and a piston rod (11). The working cylinder (4) is positioned in the oil storage tank (1). The piston rod (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 sequentially sleeved on the piston rod (11). A bottom valve assembly (2) is sleeved at the end of the piston rod (11), which extends into the working cylinder (4). Both ends of the buffer spring (6) are provided with shock pads (5) sleeved on the piston rod (11). Due to the adoption of the structure, the vibration attenuating effect of the damper can be more ideal and a vehicle is more stable in the running process.

Description

A kind of damper of the automobile vibration that is used to decay
Technical field
The utility model relates to a kind of damper, specifically is a kind of damper of the automobile vibration that is used to decay.
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.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 not enough.
The model utility content
The utility model provides a kind of damper of the automobile vibration that is used to decay, and it is undesirable to have solved automotive dampers vibration attenuation in the past, causes the not enough problem of automobile stationarity in the process of moving.
The utility model is that the technical solution problem mainly realizes through following technological scheme: a kind of damper of the automobile vibration that is used to decay; Comprise fuel tank, clutch release slave cylinder and piston rod; Clutch release slave cylinder is positioned at fuel tank, and piston rod stretches in the clutch release slave cylinder, is socketed with damping spring, guide holder assembly, oil sealing and top cover on the piston rod successively; The end that said 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 the piston rod.
Said oil sealing is provided with the packing ring that seals that is socketed on the piston rod.
Said bottom valve assembly is provided with the positioning ring that is socketed on the piston rod.
Said top cover also is socketed on the fuel tank.
The utility model compared with prior art has the following advantages and beneficial effect:
(1) the utility model 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 the fuel tank simultaneously, make that the operation of piston rod is more steady.
(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, 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, seal packing ring, 10, top cover, 11, piston rod.
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 1, clutch release slave cylinder 4 and piston rod 11, and clutch release slave cylinder 4 is positioned at fuel tank 1, and piston rod 11 stretches in the clutch release slave cylinder 4.
Be socketed with damping spring 6, guide holder assembly 7, oil sealing 8 and top cover 10 on the piston rod 11 of present embodiment successively, 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 present embodiment are provided with the beam 5 that is socketed on the piston rod 11.
The oil sealing 8 of present embodiment is provided with to be socketed in and seals packing ring 9 on the piston rod 11.
The bottom valve assembly 2 of present embodiment is provided with the positioning ring 3 that is socketed on the piston rod 11.
The working principle of the utility model is: when wheel moves 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 the vehicle body; When wheel during away from vehicle body, vehicle shock absorber is in extended state, and the piston rod 11 of damper moves upward, and damping spring 6 also is in extended state, slows down the change in displacement speed between wheel and the vehicle body equally.
As stated, then can realize the utility model well.
