Embodiment
The embodiment of the present invention is made a detailed explanation below in conjunction with the accompanying drawings.
As shown in Figs. 1-3, a kind of wear-resistant type vehicle shock absorber, the assembly include outer tube 12, inner tube 10, piston rod 14,
Piston 16 and damping unit 20, outer tube 12 is connected to the frame of vehicle, and has blind end and open end, and inner tube 10 is connected to car
Wheel, and be slidably insert into the openend of outer tube 12, inside of the inner tube 10 with inner surface and with internal diameter
Space, piston rod 14 are connected to the first end of the blind end of outer tube 12 and extend to the second end in inner tube 10, and piston 16 is fixed
Installed in the second end of piston rod 14, it is slidably fixed in inner tube 10, the inner space of inner tube 10 is divided into two sections, oil exists
In two parts of the inner space of inner tube 10, piston 16 have it is at least one limited by piston 16 and with the inside of inner tube 10
The passage of the section connection in space, when external force, which is applied to, produces impact on wheel, inner tube 10 will be slided relative to outer tube 12, living
Plug 16 will be moved along inner tube 10.Inner tube(10)Space will pass through piston(16)In passage flow to another segment, and
Compress the pressure increase in segment.Therefore, effectiveness in vibration suppression is provided with the increase of the pressure of oil.
Damping unit 20 includes plug 22 and sleeve 24, and plug 22 is connected to piston 16 and has diameter, and sleeve 24 is pacified
In inner tube 10 and there is internal diameter, the diameter of plug 22 is less than the internal diameter of the inner space of inner tube 10 and casing 24.
When inner tube 10 is moved relative to outer tube 12, the oil in the compression section of the inner space of inner tube 10 passes through first fluid
Flow to piston 16.When plug 22 enters sleeve 24, second flow channel is limited between plug 22 and sleeve 24.Due to second
The width in road is less than the width of first flow, so oil stream area reduces, oil stream amount reduces.Correspondingly, plug 22 and piston 16
Movement velocity will reduce, and be applied in the compression section of piston 16 oil pressure increase.Therefore, it is possible to effectively prevent plug
22 collision inner tubes 10, improve the impact absorbing effect of absorber.
Inner tube 10 has multiple circular orientation grooves being each defined in the inner surface of inner tube 10, and sleeve 24 is installed on interior
Between two grooves in pipe 10, two fasteners are separately mounted in groove.
The plug 22 includes the pressure-regulating valve being installed in the plug 22, and the pressure-regulating valve includes adjusting logical
Road 222, seal 26, bias piece 25, adjusting bolt 28 and branched bottom 226, the adjusting passage 222 is axially across the plug
Son 22, the passage 222 that adjusts have internal diameter and are limited to one end opposite with the piston 16 of the adjusting passage 222
Conical section 224, seal 26, which is movably mounted at, to be adjusted to close the conical section 224 of adjusting passage 222 in passage 222, partially
Component 25 is put to be installed in adjusting passage 222 and seal against component 26 to promote containment member 26 to adjust passage 222 to close
Conical section 224, adjusting bolt 28, which is screwed into, to be adjusted in passage 222 and abuts with bias piece 25, and the branched bottom 226 is radially
It is limited in plug 22 and is connected with adjusting passage 222.The diameter of seal 26 is less than the internal diameter for adjusting passage 222, and is more than
The internal diameter of conical section 224, using such pressure-regulating valve, when the oil pressure in compression section is more than the elasticity of biasing member 25,
Containment member 26 will be promoted and leave conical section 224, and passage 222 is adjusted to allow oil to be flowed into compression section.Correspondingly, press
Oil in contracting section is flowed directly into the first flow between plug 22 and inner tube 10 by adjusting passage 222 and branched bottom 226,
And provide oil pressure of the adjustment effect to compression section.When bolt 28 is tightened relative to plug 22, opened by what biasing member 25 provided
Power will be changed.
The seal 26 is ball.
In addition, spring is installed on around piston rod 14 to provide improved effectiveness in vibration suppression.
