Specific embodiment
The attached figures are only used for illustrative purposes and cannot be understood as limitating the patent；It is attached in order to more preferably illustrate the present embodiment
Scheme certain components to have omission, zoom in or out, do not represent the size of actual product；To those skilled in the art,
The omitting of some known structures and their instructions in the attached drawings are understandable.Being given for example only property of position relationship described in attached drawing
Explanation, it is impossible to be interpreted as the limitation to this patent.
Embodiment 1：
As shown in Figure 1, a kind of two-way function telescopic shock absorber with energy regenerative function, which includes 1 He of interior oil pocket of closing
Oil storage cylinder 2, piston 3, piston rod 4, upper sealing plate 11, bottom sealing plate 14, interior oil pocket 1 are arranged in oil storage cylinder 2, and upper sealing plate 11 is by interior oil
Chamber 1 and oil storage cylinder 2 are sealed, and piston 3 is mounted on interior oil pocket 1, interior oil pocket 1 are divided into upper oil cavitie and lower oil cavitie, including piston 3
It is slided in oil pocket 1, one end of piston rod 4 is connect with piston 3, and the other end stretches out interior oil pocket 1, bottom sealing plate 14 by upper sealing plate 11
The bottom of interior oil pocket 1 is arranged on, flowing valve 12 and rebound valve 13 on piston 3 are installed, recuperation valve 15 is installed on bottom sealing plate 14；
The damper is additionally provided with energy feed system, and the energy feed system includes hydraulic motor 5, check valve 6, high pressure accumulator 7, low pressure accumulation of energy
Device 8, generating set 9, accumulator group 10, the entrance of the check valve 6 are connect with lower oil cavitie, and the outlet of check valve 6 passes through threeway
Oiler of the connector respectively with the oiler of hydraulic motor 5, high pressure accumulator 7 is connect；The oil outlet of hydraulic motor 5 passes through threeway
Oiler of the connector respectively with oil storage cylinder 2, low pressure accumulator 8 is connect；Hydraulic motor 5 is connect by shaft coupling with generating set 9,
Generating set 9 is connect by electric wire with accumulator group 10.
Operation principle；The piston rod 4 of two-way function telescopic shock absorber with energy regenerative function passes through lifting lug 16 and the vehicle of vehicle
Frame connects, 2 bottom of oil storage cylinder of damper is connect by lifting lug 16 with vehicle bridge.Interior oil pocket 1 is divided into two chambers up and down by piston 3, living
4 place chamber of stopper rod is upper oil cavitie, and rear end is lower oil cavitie.Upper and lower oil pocket is connected by flowing valve 12 with rebound valve 13, respectively
Cushioning effect is played in compression travel and extension stroke；Lower oil cavitie and oil storage cylinder 2 are connected by recuperation valve 15 with energy feed system.Subtracting
It shakes in the vibration processes of device, fluid flows to high pressure accumulator 7 so as to reach the mesh of vibrational energy storage from damper through lower oil cavitie
, while the oil outlet oil pipe of oil storage cylinder 2 is connected with low pressure accumulator 8, the purpose of low pressure accumulator 8 is mended for damper
The hydraulic oil of consumption is filled, there are pressure differentials, under the action of pressure difference, hydraulic pressure horse between high pressure accumulator 7 and low pressure accumulator 8
Make directional-rotation up to 5, generating set 9 is driven to generate electricity and recover energy, stores the energy in accumulator group 10.
Specific work process；
In extension stroke, piston 3 moves up, and the fluid volume of upper oil cavitie becomes smaller, and pressure becomes larger, the fluid volume of lower oil cavitie
Becoming larger, pressure becomes smaller, and upper and lower oil pocket generates pressure difference, and fluid flows into lower oil cavitie by rebound valve 13, due to the presence of piston rod 4,
The fluid of piston upper oil cavitie is not enough to full of the increased volume of piston lower oil cavitie institute so that a part of vacuum shape occurs in lower oil cavitie
State, under the action of pressure difference, the working solution of shoe cream room 1 pushes the benefit on bottom sealing plate 14 open under the action of 8 pressure of low pressure accumulator
Valve 15 is repaid into lower oil cavitie, the deficiency thus supplemented with lower oil cavitie fluid makes compression travel later that idle running will not occur, this
8 pressure of sample low pressure accumulator declines, and pressure differential is generated between high pressure accumulator 7 and low pressure accumulator 8, when pressure difference overcomes enough
During 5 resistance of start of hydraulic motor, hydraulic motor 5 drives generating set 9 to generate electricity, and energy is converted into power storage in accumulator group
In 10.
In compression travel, piston 3 moves down, and the lower oil cavitie volume of interior oil pocket 1 becomes smaller, pressure increase, the fluid of upper oil cavitie
Volume becomes larger, and pressure becomes smaller, and fluid flows to upper oil cavitie through flowing valve 12, is less than lower oil cavitie reduction appearance since upper oil cavitie increases volume
Product, therefore check valve 6 of the partial high pressure fluid through lower oil cavitie flows into high pressure accumulator 7,7 pressure rise of high pressure accumulator, in height
Pressure differential is generated between pressure accumulator 7 and low pressure accumulator 8, when pressure difference overcomes 5 resistance of start of hydraulic motor enough, hydraulic pressure horse
It generates electricity up to 5 drive generating sets 9, energy is converted into power storage in accumulator group 10, realizes recycling vibrational energy.
