Buffer unit is provided between upper cushioning fender；Buffer unit is including in disk spring, base, upper end cover, block rubber, guiding
Cylinder, it is oriented to outer barrel and disconnecting prevention structure；Base is connected with piston stand；The upper surface for being oriented to outer barrel and base connects, and is oriented to inner cylinder
It is connected with the lower surface of upper end cover, is oriented to inner cylinder insertion and is oriented to outer barrel and is axially movable；Disk spring is in guiding inner cylinder
And support upper end cover；Disconnecting prevention structure can avoid the guiding inner cylinder in the case where disk spring elastic force acts on from being separated with being oriented to outer barrel；Rubber
The upper surface of block and upper end cover connects.
It is further：Disconnecting prevention structure include mousing-hook and be arranged on guiding outer barrel on anticreep flange, mousing-hook with it is upper
End cap is connected, and when guiding inner cylinder is moved up to extreme position under the effect of disk spring elastic force, anticreep flange is hooked in mousing-hook.
It is further：It is oriented to outer barrel lower end and is provided with mudhole.
It is further：Buffer unit is provided between T stage frame and T-shaped rack bracket.
The beneficial effects of the utility model are：(1) in piston uphill process, buffer unit and cushioning fender on T stage frame
Contact, by the retractility of pressing of buffer unit disk spring, ensure piston stand and T stage frame flexible contact；And buffering dress
Put appropriateness and add rigidity, while there is flexibility, reduce former rubber buffer and be extruded the damaged risk for bringing tilting of the piston.
(2) due to the flexibility that disk spring is brought, the impulsive force that block rubber is subject to when being hit is relatively reduced, is advantageous to carry
The life-span of high block rubber.
