Brief description of the drawings
Fig. 1 is a kind of structural representation of the tank body of an embodiment of vapour Vehicle Accumulator of the invention；
Fig. 2 is a kind of structural representation of the piston of an embodiment of vapour Vehicle Accumulator of the invention；
Fig. 3 is a kind of structural representation of vapour Vehicle Accumulator of the invention.
Embodiment
Fig. 1-3 schematically shows the vapour Vehicle Accumulator of one embodiment of the present invention.As shown in figure 1, the automobile
Include tank body 1 and piston 2 with accumulator.The inwall of tank body 1 is processed by rolling technology, improves the inwall top layer of tank body 1
Finish and reinforcing ultimate strength, improve performance, fatigue resistance, wearability and the corrosion resistance of workpiece, total for extension
Into service life provide basic factors.Activity is equipped with piston 2 in the opening of tank body 1.The opening of piston 2 is towards tank body 1
Inner chamber.The confined space that the inner chamber of tank body 1 and the inner chamber of piston 2 collectively form for accommodating working gas is energy storing space 61.
Tank body 1 sets the lateral wall of the one end of opening to be provided with external screw thread 13, is engaged with the internal thread in hydraulic system, by outer
Accumulator is arranged in hydraulic system by the spiral shell connection of screw thread 13 and internal thread.In order to ensure the sealing of tank body 1 and hydraulic system
Fluted 11 are opened up on performance, the lateral wall of tank body 1, groove 11 is provided with O-ring 12.The bottom of tank body 1 couples provided with installation
The polygon counterbore 14 of power, installs connection and puts forth effort polygon counterbore 14 to install the connection impetus of accumulator, when installing accumulator, make
Installation connection is inserted in instrument and puts forth effort rotation drive accumulator fastening installation after polygon counterbore 14.In this embodiment, connection is installed
Adhesion 14 hexagonal counterbores of polygon counterbore, are inserted in rotation after hexagonal counterbore using inner hexagon spanner and drive accumulator fastening to pacify
Dress.
First precharge of gas, to pressure is set, the accumulator of the aerobic body of preliminary filling is pacified in energy storing space 61 before accumulator is installed
It is attached in hydraulic system, now, the both sides of piston 2 are respectively energy storing space 61 and working space 62.When automotive transmission works
There is high or low pressure and acts on the end face of piston 2 in hydraulic system：When the operating pressure of hydraulic system is more than energy storing space 61
When setting pressure, the gas in energy storing space 61 is further compressed, and is formed compression energy and is stored in energy storing space 61, together
When with the movement of piston 2, concede the system pressure of more spatial balance hydraulic systems；When the operating pressure of hydraulic system is less than
The energy set in the compressed gas in pressure, energy storing space 61 is released, and the compression energy being stored in energy storing space 61 is pushed away
Piston 2 works, and increases energy storing space 61, supplements the system pressure of hydraulic system, realizes the balance of hydraulic system.In order to more preferable
Above-mentioned pressure regulation process is realized on ground, makes the pressure of hydraulic system more steady.The lateral wall of piston 2 and the madial wall of tank body 1
Between be provided with the first guide ring 31, sealing ring 4, extrusion ring 5, the second guide ring 32 and snap ring 6.On the lateral wall of piston 2 respectively
Offer for place the first guide ring 31 the first neck 21, for place the second neck 22 of sealing ring 4 and extrusion ring 5 with
And for placing the 3rd neck 23 of the second guide ring 32.First guide ring 31 and the second guide ring 32 are located at sealing ring 4 respectively
With the both sides of extrusion ring 5.First guide ring 31 is close to the opening of piston 2, and sealing ring 4 leans on close to the first guide ring 31, extrusion ring 5
Nearly second guide ring 32.Sealing ring 4 seals, and prevents gas from revealing.The guide ring of both sides is for supporting piston 2 and drawing
Lead it to move towards to slide along tank body 1, prevent that piston 2 from directly occurring to contact firmly with the inwall of tank body 1 and causes damage, while second leads
The hydraulic oil on the inwall of tank body 1 can tentatively be removed in reciprocating motion to ring 32.The width of the second neck 22 is increased,
One of extrusion ring 5 is added in two draw-in groove 22, ring is directed to and fails to remove the secondary removing of clean hydraulic oil, effectively prevent accumulation of energy
The initial failure of device.Extrusion ring 5 is interference fitted with tank body 1.Extrusion ring 5 coordinates with the inner chamber slight interference of tank body 1, can effectively remove tank
Hydraulic oil on the inwall of body 1, had both prevented from bringing oil into working space 62, the also reciprocating motion for piston 2 creates favorable conditions.For
The inertia force for eliminating weight change caused by increase extrusion ring 5 and bringing, the end of the inner chamber of piston 2 is provided with loss of weight step,
The weight in the case where meeting use condition of piston 2 is most gently changed, reduce inertia force in the course of work and act on, whole accumulator work is more
Steadily.In order to prevent piston 2 from departing from tank body 1, piston 2 is not provided between the lateral wall of end of opening and the madial wall of tank body 1
It is additionally provided with snap ring 6.
Above-described is only some embodiments of the present invention.For those of ordinary skill in the art, do not taking off
On the premise of the invention design, various modifications and improvements can be made, these belong to protection scope of the present invention.
