Abstract
The utility model discloses a guider of a shock absorber. The guider of the shock absorber comprises a guider body (1) which is provided with an annular outer sealing surface (2), wherein the outer sealing surface (2) is provided with 4-8 notches (3) which are convenient for hydraulic oil to flow in and flow out; and the notches (3) are arranged uniformly along the annular outer sealing surface (2). The flow passing through the guider of the shock absorber is more uniform.
Description
Technical field
The utility model relates to a kind of auto parts and components field, specifically relates to a kind of guider that is used for the vibration damper of automobile shockproof system.
Background technique
Automobile is through uneven road surface the time, though the shock-absorbing spring in the shockproof system can filter the vibrations on road surface, spring self also has to-and-fro motion, and vibration damper is used for suppressing the back and forth jump of this spring.The structure of vibration damper is that the piston rod that has piston inserts in the tube, is full of oil in the tube.Throttle orifice is arranged on the piston, make that the oil in two-part space that is separated by piston can complement each other.The working principle of vibration damper is when receiving vibrations relative movement to occur between vehicle frame and vehicle bridge or vehicle body and vehicle bridge; Piston in the vibration damper moves up and down; Fluid in the vibration damper chamber just flows in another chamber from a chamber through different holes 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.
Guider is one of strength member in the vibration damper; It plays good leading role to the motion of piston rod in the vibration damper, guarantees the smoothness of piston in running, and the oilhole through guider is communicated with clutch release slave cylinder and oil storage cylinder in the piston motion process simultaneously; Existing technology generally is on guider annular external sealed face, to open 3 notches to play the runner effect; Because notch quantity is few, the hydraulic oil in the annular sealing surface all pours in this 3 notches, interacts between the hydraulic oil and impacts each other; And piston when motion piston axis and the guider center line between have small inclination; Distance is bigger between 3 notches, and the hydraulic oil that receives impacts incomplete same, makes from the hydraulic fluid flow rate of 3 notches outflows inhomogeneous.
The model utility content
The utility model technical problem to be solved is that the guider of the more uniform a kind of vibration damper of flow is provided.
The technical solution of the utility model is; The guider of a kind of vibration damper with following structure is provided; It comprises the guider body that is provided with annular external sealed face; Said external sealed face is provided with the notch that makes things convenient for hydraulic oil to flow out and flow into, and said notch is 4～8, and said notch is evenly distributed along annular external sealed face.
After adopting above structure, the guider of a kind of vibration damper of the utility model compared with prior art has following advantage:
Because outer circumferential face is provided with 4～8 notches on the guider body in the guider of a kind of vibration damper of the utility model; And notch is evenly distributed along annular external sealed face, because notch quantity increases, the distance between the notch diminishes; The hydraulic oil impact force gap that adjacent notch receives diminishes; And owing to set up notch, the mutual impact between the hydraulic oil reduces, and makes that the hydraulic fluid flow rate between the adjacent notch is more even.
As preferably, said external sealed face is provided with four notches, and four notches are evenly distributed along annular external sealed face, and locate easily at the notch center, convenient processing.
As improvement, said notch extends out, and outside notch cross sectional area increases, and hydraulic oil flows out milder.
As preferably, said notch both sides extend out angle and are 3 °～8 °, and the notch both sides extend out milder, and hydraulic oil flows out milder.
As improvement, said annular external sealed face outward edge is provided with hollows, relies on the sealing of external sealed face intermediate portion, seals tighter.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done explanation in further detail.
Shown in please seeing figures.1.and.2; The guider of a kind of vibration damper of the utility model; It comprises the guider body 1 that is provided with annular external sealed face 2; Said external sealed face 2 is provided with the notch 3 that makes things convenient for hydraulic oil to flow out and flow into, and said notch 3 is 4～8, and said notch 3 is evenly distributed along annular external sealed face 2.
Said external sealed face 2 is provided with four notches 3.
Said notch 3 extends out, and said notch 3 extends out and is meant, notch 3 is big near the sectional area of inboard near the sectional area ratio in the outside.
Said notch 3 both sides extend out angle and are 3 °～8 °.
Said annular external sealed face 2 outward edges are provided with hollows 4.
