Detailed description of the invention
With reference to Fig. 2, Fig. 3, a kind of inversion type front damping device for motorcycle, including upper sleeve pipe 1 and lower breeches pipe 2；Described lower breeches pipe 2
Annular seal space 3 is formed in stretching into described upper sleeve pipe 1；It is provided with piston rod 4 in described upper sleeve pipe 1, outside described piston rod 4, is socketed with sealing
Stretch into the piston component 5 in described lower breeches pipe 2, make the lower breeches pipe 2 below described piston component 5 be internally formed discharge chambe 31；Institute
State lower breeches pipe 2 inwall to be arranged over check valve 6 at the most described piston component 5 and engage with described piston rod 4 outer wall, make described work
Forming recovery room 32 between plug assembly 5 and described check valve 6, the other parts of described annular seal space 3 then constitute air chamber 33.
Wherein, described piston component 5 is communicated with the damp channel 51 of described discharge chambe 31 and recovery room 32；Described unidirectional
6, valve allows the damping oil in described air chamber 33 to flow to realize the pressure balance in dynamic stroke toward described recovery room 32；
Described piston rod 4 is hollow pipe through to described discharge chambe 31, and its hollow pipe tube wall is provided with throttle orifice 41 and connects described pressure
Contracting room 31 and described air chamber 33.
When amortisseur is compressed action, piston component 5 down moves and makes the volume reducing of discharge chambe 31, pressure increase
Greatly；The now damping oil in discharge chambe 31, one is that the damp channel 51 on piston component 5 flows to recovery room 32 and produces damping
Effect, two is the piston rod 4 by hollow in throttle orifice 41 is back to air chamber 33, for avoiding flowing into the oil of air chamber 33
Amount too much, causes the damping oil deficiency flowing into recovery room 32 to form negative pressure, can avoid by controlling the aperture of throttle orifice 41
State problem；Damping oil in air chamber 33 synchronizes to flow in recovery room 32 through check valve 6 simultaneously, it is to avoid recovery room 32 increases because of volume
Produce negative pressure greatly；Now three operating rooms pressure relation in compression travel is: P32 ＜ P31 ＞ P33.
When restoring action made by amortisseur, piston component 5 up moves under damping spring effect and makes recovery room 32
Volume reducing, pressure increase, and now the damping oil in recovery room 32 cannot be flowed to air chamber 33 by check valve 6, can only pass through
Damping hole 51 on piston component 5 flows to discharge chambe 31 and produces damping；And the volume of discharge chambe 31 synchronizes to increase, restore
The damping oil that room 32 is provided is not enough to be fully filled with the piston-rod volume part damping oil that discharge chambe lacks, by throttle orifice 41
Automatically being supplemented in discharge chambe 31 from air chamber 33 with the hollow hole of piston rod 4, now three operating rooms are in restoring stroke
Pressure relation is: P32 ＞ P31≤P33.
With reference to Fig. 4, for the simplicity producing, assembling and reduce cost further, upper sleeve pipe 1 can be divided into urceolus 11 and
The upper end cover 12 that upper end open is fixed；Piston rod 4 one end is fixed on end cap 12；And, lower breeches pipe 2, axletree retainer 22；
Lower breeches pipe 2 bottom opening seals and is fixed with plug screw 23.
With reference to Fig. 5, Fig. 6, the damping that damp channel 51 shows, realized by the structure of described piston component 5, bag
Include and be fixed on the piston 53 on described piston rod 4 by valve seat 52 sandwiched；Described piston 53 two ends are all fitted with one or more pieces
Valve block 54, and make described piston 53 two ends shift to install fluted 55 to make described damp channel 51 in unidirectional open state, upper end
The valve block 54 adjacent with recovery room 32 is provided with shell fragment 56.During compression travel, discharge chambe 31 oil pressure is more than the oil pressure of recovery room 32, on
End valve sheet 54 upwarps and makes damp channel 51 in channel status, and damping oil flows to recovery room 32 from discharge chambe 31, until pressure differential is little
In the active force that shell fragment 56 is applied；During reduction stroke, then valve block 54 below piston 53 has a downwarp conducting, and damping oil is from recovery room
32 flow to discharge chambe 31；Integral damping simple in construction, damping capacity is reliable and stable.
And amortisseur is in addition to damping structure, the scope according to stroke that generally also needs to arranges limiting buffer structure, can be
Being installed with guide holder 7 at the upper shed of described lower breeches pipe 2, described guide holder 7 plays guide effect for piston rod 4 cross-under；On described
Sleeve pipe 1 top is provided with limiting buffer block 8.Described limiting buffer block 8 includes cushion pad 81 and the hard gasket 82 arranged below；
Hard gasket 82 is placed on the step of sleeve pipe 1 inwall and makes cushion pad 81 not come off, and cushion pad 81 can be prevented at lower fork
The directly impact of pipe 2 is lower to be damaged.
There is gap between described upper sleeve pipe 1 inwall and described lower breeches pipe 2 outer wall and form extension chamber 9；Described lower breeches pipe 2 is right
The sidewall answering described recovery room 32 is provided with through hole 211 and connects with described extension chamber 9, and extension chamber 9 can synchronize to be pressed with recovery room 32
Contracting or recovery, make the volume of recovery room 32 be expanded, and the most persistently ensures damping, provides table in upper sleeve pipe 1 simultaneously
Face and the lubrication of lower breeches pipe 2 outer surface and sealing, the assembling of amortisseur when being beneficial to produce.
After using technical scheme, by directly oil cylinder being integrated in lower breeches pipe 2, and piston rod 4 is arranged
For hollow and by throttle orifice 41, described discharge chambe 31 and described air chamber 33 are connected, coordinate the damping of piston component 5 self
Passage 51 and check valve 6, thus constitute the complete damping structure of shock absorber, eliminate the damper tube oil cylinder in existing structure and the end
Valve, the frame mode of the most built-in damper tube is the simplest mutually, and manufacturing cost is minimized, and ensures the performance of amortisseur simultaneously
Stable, good damping effect.
