Specific implementation mode
Specific embodiment of the present utility model 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 vehicle
Wheel, and be slidably insert into the open end 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
It mounted on the second end of piston rod 14, 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 channel of the section connection in space, when external force, which is applied to, generates 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 channel flow to another segment, and
The pressure compressed in segment increases.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 to be less than the internal diameter of the inner space of inner tube 10 and sleeve 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 the oil pressure that is applied in the compression section of piston 16 increases.Therefore, it is possible to be effectively prevented plug
22 collision inner tubes 10, improve the impact absorbing effect of absorber.
There are inner tube 10 multiple circular orientation grooves being each defined in the inner surface of inner tube 10, sleeve 24 to be mounted on interior
Between two grooves in pipe 10, two fasteners are separately mounted in groove.
The plug 22 includes the pressure-regulating valve being mounted in the plug 22, and the pressure-regulating valve includes adjusting to lead to
Road 222, sealing element 26, bias piece 25, adjusting bolt 28 and branched bottom 226, the adjusting channel 222 is axially across the plug
Son 22, the channel 222 that adjusts have internal diameter and are limited to described one end opposite with the piston 16 for adjusting channel 222
Conical section 224, sealing element 26, which is movably mounted at, to be adjusted to close the conical section 224 for adjusting channel 222 in channel 222, partially
Casting die 25, which is mounted on, adjusts in channel 222 and seals against part 26 to push sealing element 26 to close the taper for adjusting channel 222
Section 224, adjusting bolt 28 be screwed into adjust channel 222 in and with bias piece 25 abut, the branched bottom 226 it is radially defined
It is connected in plug 22 and with channel 222 is adjusted.The diameter of sealing element 26 is less than the internal diameter for adjusting channel 222, and is more than conical section
224 internal diameter utilizes such pressure-regulating valve, when the oil pressure in compression section is more than the elasticity of bias piece 25, sealing element 26
It will be pushed and leave conical section 224, channel 222 is adjusted to allow oil to be flowed into compression section.Correspondingly, the oil in compression section
It is flowed directly into the first flow between plug 22 and inner tube 10 by adjusting channel 222 and branched bottom 226, and adjusting is provided
It is applied to the oil pressure of compression section.When bolt 28 is tightened relative to plug 22, the tension provided by bias piece 25 will be changed.
The sealing element 26 is ball.
In addition, spring is mounted on around piston rod 14 to provide improved effectiveness in vibration suppression.
