Background technique
The main structure of vehicle shock absorber inserts in cylinder with the piston rod of piston, is full of oil, piston has throttle orifice in cylinder, and the oil in two-part space separated by piston can be complemented each other.The working principle of vehicle shock absorber is: when vehicle frame and vehicle bridge or between vehicle body and vehicle bridge vibrated there is relative movement time, piston in vehicle shock absorber moves up and down, fluid in vehicle shock absorber chamber just flows in another chamber from a chamber through different holes repeatedly, friction now between hole wall and fluid and the intermolecular interior friction of fluid form damping force to vibration, make automobile vibrational energy be converted into fluid heat energy, then be dispersed in air by vehicle shock absorber absorption.
Guider is one of strength member in vehicle shock absorber, mainly the piston rod be slidably mounted in vehicle shock absorber clutch release slave cylinder is play the guiding role, ensure the smoothness of piston in running, and by the oil-through hole of guider, fluid unnecessary in clutch release slave cylinder being transported in oil storage cylinder in piston movement process, guarantee clutch release slave cylinder is communicated with oil storage cylinder.
Existing guider is generally arrange endoporus on guider body, and lining is set on the inwall of endoporus, be slidably matched by lining and piston rod and realize moving up and down of piston, come off from the inwall of endoporus to not allow lining, lining and endoporus interference fit are set usually, the fit tolerance of interference fit is larger, lining more can be securely fixed on endoporus, but be but difficult to lining to be encased in endoporus during assembling, so just between the tightness and the complexity of installation of interference fit, define conflict.
Model utility content
The technical problems to be solved in the utility model is: provide a kind of lining difficult drop-off and the easy guide device used in automobile shock absorber of assembling.
Technical solution of the present utility model is: a kind of guide device used in automobile shock absorber, comprise guider body, described guider body is provided with the endoporus of the piston rod for installing vehicle shock absorber, the inwall of described endoporus is provided with the lining for being slidably matched with piston rod, described lining and endoporus interference fit, it is characterized in that: the top of described endoporus is radially-inwardly provided with annular protrusion, the bottom of described annular protrusion arranges ring magnet, described lining is made up of non-magnet material, the top of described lining arranges the ring that permeability magnetic material is made, the upper surface of the ring that the lower surface of the ring magnet bottom described annular protrusion and the permeability magnetic material at lining top are made is attracting by the magnetic force formed each other.
After adopting said structure, the utility model has the following advantages:
The utility model guide device used in automobile shock absorber is except arranging lining and endoporus interference fit, on endoporus, also arrange annular protrusion makes lining not easily come off from endoporus for leaning lining, respectively ring magnet is set bottom annular protrusion in addition, and the ring that permeability magnetic material makes is set at lining top, the magnetic force formed is utilized tightly to hold between the two, further enhance the fastness of lining in endoporus, due to the setting of annular protrusion and magnetic texure, also the fit tolerance of interference fit is made to design too much, also can lining be fixedly secured in endoporus, thus also facilitate assembling, and the setting of magnetic texure has also further facilitated assembling.
As preferably, the bottom of described annular protrusion arranges first ring connected in star, and described ring magnet is embedded in first ring connected in star, and the top of described lining arranges the second annular groove, and the ring that described permeability magnetic material is made is embedded in the second annular groove.This setting can reduce magnetic force that ring that ring magnet and permeability magnetic material make formed to the impact of peripheral parts.
As preferably, described guider body is also provided with oil sealing end die cavity, the wall thickness above described oil sealing end die cavity is less than wall thickness below.The arrangement increases the wall thickness of oil sealing end die cavity bottom, add the intensity of guider entirety, and shaping depanning is more prone to.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
In figure: 1-guider body, 2-endoporus, 3-piston rod, 4-lining, 5-annular protrusion, 6-ring magnet, the ring that 7-permeability magnetic material is made, 8-first ring connected in star, 9-second annular groove, 10-oil sealing end die cavity.
