Abstract
The utility model discloses a three-cylinder self-adaptive shock absorber which comprises a working cylinder (2), an oil storage cylinder (3) and an outer cylinder (4), wherein the oil storage cylinder (3) and the outer cylinder (4) are sequentially connected in the working cylinder (2) in a sleeved mode. An oil guiding channel (11) is formed between the working cylinder (2) and the oil storage cylinder (3), an oil storage cavity (10) is formed between the oil storage cylinder (3) and the outer cylinder (4), the outer cylinder (4) is divided by a piston tightly connected with the inner wall of the outer cylinder (4) into an upper cavity (9) and a lower cavity (12), a one-way flow valve (5) is arranged on the piston, the upper cavity (9) is connected with one end of the oil guiding channel (11) through a flow hole in a guiding device (1), the other end of the oil guiding channel (11) is connected with the oil storage cavity (10) and the lower cavity (12), and a damping valve (7) and a one-way compensation valve (6) are sequentially arranged between the oil guiding channel (11) and the lower cavity (12). The three-cylinder self-adaptive shock absorber has the advantage that on the premise that original suspension characteristics are not changed, the buffering effect is good.
Description
Technical field
The utility model relates to a kind of damping device in auto parts and components production field, particularly a kind of three self-adapting type vibration dampers.
Background technique
Automobile absorber is that buffering automobile jolting of being subject to that road surface, obstacle cause brings the impact of vehicle body, and the safety and comfort that it not only can protect occupant, can also improve the handling of automobile.If vibration damper lost efficacy or damaged, will directly have influence on cruising characteristic and the riding comfort of automobile, also can affect the working life of auto parts and components simultaneously.
In automobile suspension system, extensively adopt hydraulic damper.Its principle is, in the time that vehicle frame and vehicle bridge are done reciprocal relative movement and move back and forth in the cylinder barrel of piston at vibration damper, the fluid in vibration damper housing just flows into another inner chamber from inner chamber by some narrow holes repeatedly.Now, the interior friction of the friction of liquid and inwall and fluid molecule just forms the damping force to vibration.But existing hydraulic damper is still being weak aspect the adaptivity ability to abnormal impact, in the time being subject to extremely impacting, fluid in vibration damper housing there will be the phenomenon of two-way flow, cannot obtain accurate buffer damping characteristic, causes in the time that automobile is subject to extremely impacting damping effect not good.
Summary of the invention
The defect existing for existing hydraulic damper, the utility model provides a kind of three self-adapting type vibration dampers.
To achieve these goals, technical solution adopted in the utility model is:
A kind of three self-adapting type vibration dampers, comprise clutch release slave cylinder and be connected to piston rod upper piston, in clutch release slave cylinder, be socketed with successively fuel tank and outer shell, the top of outer shell and fuel tank is connected with the top of clutch release slave cylinder by guider, between clutch release slave cylinder and fuel tank, be provided with Oil Guide passage, between fuel tank and outer shell, be provided with oil storage chamber, with the close-connected piston of the outer inside wall of cylinder, outer shell is divided near the epicoele of top one side and the cavity of resorption of close low side one side, on piston, be provided with flowing valve, the epicoele of outer shell is connected with one end of Oil Guide passage by the opening in guider, the other end of Oil Guide passage is connected with cavity of resorption with oil storage chamber, between Oil Guide passage and cavity of resorption, be disposed with the inertia damping valve and the recuperation valve that are connected to outer shell bottom, flowing valve and recuperation valve are one-way cock,
The bottom of described outer shell and fuel tank is connected with the bottom of clutch release slave cylinder by coasting body;
Described flowing valve, recuperation valve and inertia damping valve are the solenoid valve of electronic control or other automatic controlling system.
The beneficial effects of the utility model: when normal vehicle operation, coasting body in fixing working position, can be suspension normal damping characteristic is provided under the compressing of spring and liquid stream; Adopt inertia damping valve to realize the adaptivity to abnormal impact, use coasting body can be when vehicle normal acceleration reaches setting value, complete the unlatching of setting or the action of throttle down, and then in the time that being subject to extremely impacting, vehicle obtains buffer damping characteristic more accurately, not changing under original suspension performance prerequisite, can provide better cushioning effect.

Embodiment
A kind of three self-adapting type vibration dampers, comprise clutch release slave cylinder 2 and be connected to piston rod upper piston, in clutch release slave cylinder 2, be socketed with successively fuel tank 3 and outer shell 4, the top of outer shell 4 and fuel tank 3 is connected with the top of clutch release slave cylinder 2 by guider 1, between clutch release slave cylinder 2 and fuel tank 3, be provided with Oil Guide passage 11, between fuel tank 3 and outer shell 4, be provided with oil storage chamber 10, with the close-connected piston of outer shell 4 inwall, outer shell 4 is divided near the epicoele 9 of top one side and the cavity of resorption 12 of close low side one side, on piston, be provided with flowing valve 5, the epicoele 9 of outer shell 4 is connected with one end of Oil Guide passage 11 by the opening in guider 1, the other end of Oil Guide passage 11 is connected with cavity of resorption 12 with oil storage chamber 10, between Oil Guide passage 11 and cavity of resorption 12, be disposed with the inertia damping valve 7 and the recuperation valve 6 that are connected to outer shell 4 bottoms, flowing valve 5 and recuperation valve 6 are one-way cock, the bottom of described outer shell 4 and fuel tank 3 is connected with the bottom of clutch release slave cylinder 2 by coasting body 8, described flowing valve 5, recuperation valve 6 and inertia damping valve 7 are the solenoid valve of electronic control or other automatic controlling system.
Working principle of the present utility model: because the flowing valve 5 arranging on the bottom at clutch release slave cylinder 2 and piston, recuperation valve 6 are one-way valves, so no matter be to stretch or compression, fluid in vibration damper epicoele 9 is all that the external Oil Guide passage 11 between opening and outer shell 4 and the fuel tank 3 through arranging on the guider 1 with opening enters base lower end, and pushes orifice valve 7, recuperation valve 6 open and enter the oil storage chamber 10 of cavity of resorption 12 or fuel tank 3.No matter vibration damper is in the time that stretching is still compressed, and all can ensure the one-way flow of fluid.
The beneficial effects of the utility model: when normal vehicle operation, coasting body in fixing working position, can be suspension normal damping characteristic is provided under the compressing of spring and liquid stream; Realize the adaptivity to abnormal impact owing to adopting inertia damping valve, use coasting body can be when vehicle normal acceleration reaches setting value, complete the unlatching of setting or the action of throttle down, and then in the time that vehicle is subject to extremely impacting, obtain buffer damping characteristic more accurately, reach better cushioning effect.The simple replacement of those ordinary skill in the art and replacing are all within this patent protection domain.
