Abstract
A multistage oil-gas driving type vehicle damper is composed of an upper fixing support, a lower fixing support, a pressure piston push rod and an oil cylinder barrel having connection and driving damping functions. One end of the pressure piston push rod is connected with the upper fixing support, the other end of the pressure piston push rod stretches into the oil cylinder barrel from the top of the oil cylinder barrel, and the bottom end of the oil cylinder barrel is connected with the lower fixing support. The multistage oil-gas driving type vehicle damper is characterized in that a cavity capable of accommodating air and hydraulic oil is formed in the pressure piston push rod, a spring set is fixed on the upper portion of the cavity, a plurality of through holes are formed in the bottom end face of the cavity, and a washer capable of moving up and down along a screw rod is connected to the center of the bottom end face of the cavity through the screw rod; the cavity capable of accommodating air and hydraulic oil is formed in the oil cylinder barrel, an energy conversion piston is arranged in the center of the cavity, and a compression spring set is fixed on a bottom plate in the oil cylinder barrel. The damper is simple in structure and few in component, the number of components is reduced by 30% compared with that of an existing damper, the damping effect is obviously improved, and the damper is suitable for various vehicles.
Description
Technical field
The present invention relates to a kind of shock absorber for vehicle, is a kind of multi-grade oil, the gas active vehicle vibration damper that can respond in the instant specifically.
Background technique
Current known Vehicular damper, more advanced is to adopt the liquid-springing structure, it is by wear-resisting withstand voltage as the glue piston, in oil cylinder, allowing and move up and down, promote in-oil cylinder hydraulic oil through a stress reduction device, make hydraulic oil flow through reduction valve under surge pressure, control compression speed and carry out vibration damping, but mainly there is following defect in existing dydraulic shock absorber: the one, and the single-stage effectiveness in vibration suppression is undesirable, during fluctuating road surface when vehicle in less highway section, the mode of existing passive vibration damping, lose effectiveness in vibration suppression because compression stroke is less, the 2nd, the road surface that Vehicle Driving Cycle is very large in fluctuations, while needing large stroke to carry out vibration damping, existing vibration damper can't complete, main cause is the solution pressure valve due to vibration damper, the hydraulic oil of controlling can not complete large stroke in the short time, and make vibration damping not reach best effectiveness in vibration suppression, so just make vehicle lose the vibration damping protection.
Summary of the invention
For overcoming the above-mentioned defect of existing single-stage passive type vibration damper, the invention provides a kind of multi-grade oil, gas active vehicle vibration damper, to guarantee that vehicle has best effectiveness in vibration suppression on various road surfaces, make Vehicle Driving Cycle as far as possible steadily.
For solving its technical problem, the technical solution used in the present invention is: the multi-grade oil of designing, gas active vehicle vibration damper, by upper fixed support, lower fixed support, pressure piston push rod with play and be connected and the cylinder tube of active damping effect forms, wherein: an end of pressure piston push rod is connected with upper fixed support, the other end extend in cylinder tube from the cylinder tube top, and the bottom of cylinder tube is connected with lower fixed support; Its feature is: be provided with the cavity that can contain air and hydraulic oil in described pressure piston push rod 1., the top of this cavity is fixed with cluster spring, the end face of this cavity bottom is provided with a plurality of through holes, at the bottom end face center of this cavity by screw rod be connected with can be up and down along this screw rod packing ring; Be provided with the cavity that can contain air and hydraulic oil in cylinder tube, the middle part of this cavity is provided with the transformation of energy piston, on the base plate in cylinder tube, is fixed with compression spring set.2. the bottom end face of pressure piston push rod is connected with described transformation of energy piston by screw rod, and the diameter of this transformation of energy piston is slightly less than the diameter of pressure piston push rod inner cavity.3. the end face of described pressure piston push rod cavity bottom is provided with 4-8 through hole, and what at the bottom end face center of this cavity, by screw rod, connect can also be provided with 4-8 through hole on the packing ring up and down along this screw rod.4. the through hole on the bottom end face of described pressure piston push rod cavity, its diameter is greater than the diameter of through hole on described packing ring.5. described cluster spring and compression spring set form by many rubber springs.
With existing single-stage ride-control, compare, the present invention has following characteristics and progress: 1. because the present invention adopts the independently gentle row compression vibration damping of compressing into of oil pressure of upper and lower two-stage, when vehicle is subject to less external impacts, the compressing spring of cylinder tube bottom can be stressed, play buffer function, make the vehicle held stationary; When vehicle is subject to larger external impacts, cylinder tube can upwards push away, and the cluster spring in the pressure piston push rod is shunk, and in upper and lower two independences, can mutually compensate again under the protection of vibration damping, and vehicle can travel held stationary; 2. because vibration damper of the present invention can well be dissolved impact strength, can reduce the noise that travels of vehicle, the reducing of impact force also can reduce car resistance, can correspondingly reduce oil consumption; 3. through the experiment contrast, this ride-control is simple in structure, and constituent elements is few, than the component of existing vibration damper, reduces 30%, and effectiveness in vibration suppression obviously improves; 4. the Component due to this vibration damper reduce, and can improve 1-2 the working life of product doubly.
