To achieve these goals, the utility model provides a kind of buffer, comprise first cylinder sleeve, piston and piston rod, described piston is divided into first chamber and second chamber with first cylinder sleeve, described buffer also comprises first integrated package, second integrated package and second cylinder sleeve, described first integrated package seals described first chamber, described second integrated package seals described second chamber, described second cylinder sleeve is set in the described first cylinder sleeve outside, and and described first cylinder sleeve, first integrated package and second integrated package formation shoe cream room.

Preferably, be provided with oil duct in described first integrated package and second integrated package, described shoe cream room is communicated with first chamber and second chamber respectively by described oil duct.

Preferably, all damping control valve doors are arranged in the described oil duct, can various damping control valve doors be set according to the control needs in oil duct, play different dampings.

Preferably, described second integrated package is connected with second cylinder sleeve by flange body.

Preferably, described first integrated package is provided with o-ring groove, and one group of Sealing is installed in o-ring groove.

More preferably, described second cylinder sleeve is cylinder type hollow column structure or quadrilateral or other polygon hollow column structure.

The utlity model has following beneficial effect:

1, simple in structure, compact, do not need external oil line pipe and external fuel tank, easy to use, saved usage space, greatly reduce rate of fault.

2, manufacture cost reduces, and is easy for installation, improved the market competitiveness.

3, owing to do not use external oil line pipe, shortened the stroke of hydraulic oil greatly, improved damping.
