Abstract
The invention discloses a gas-oil separation vehicle vibration damper. The vibration damper comprises an upper mounting hanging ring, a lower mounting hanging ring, an oil tank and a piston rod and is characterized in that: the piston rod is arranged in the oil tank; an energy reduction and exchange valve is arranged at the bottom of the piston rod; the top end of the piston rod passes through a guide sleeve, then is inserted into an oil tank top plate and is connected with the upper mounting hanging ring; the piston rod is a sealed hollow cylinder; a movable type air piston is arranged in the inner cavity of the piston rod; and an air bag is arranged between a movable type air piston rod in an air piston rod and the rod top. The vibration damper is an oil-gas two-stage vibration damper actually and has a vibration damping effect which is obviously better than that of the conventional one-stage vibration damper only with one oil tank. The vibration damper has a simple structure and a good vibration damping effect and can make a vehicle operated stably and safely and make passengers feel comfortable and environmentally friendly; the service life of the vibration damper can be prolonged; the exchange amount of the vibration damper can be reduced; a maintenance cycle can be prolonged; the reduction in the using cost is facilitated; and the vibration damper is suitable for an automobile or other motor vehicles.
Description
[technical field] the present invention relates to a kind of motor vehicle vibration damping equipment, is a kind of Oil-gas Separation ride-control specifically.
[background technique] present known Motor Vehicle vibration damper, more advanced is the liquid-springing structure, it is to move up and down in oil cylinder by a wear-resisting withstand voltage rubber piston, promotes in-oil cylinder hydraulic oil through a stress reduction device, makes hydraulic oil play effectiveness in vibration suppression under certain pressure.But present dydraulic shock absorber mainly contains following defective:
The single-stage effectiveness in vibration suppression is undesirable, the vibration damper of current all uses is because design deficiency, can only passive vibration damping can not active damping, when when vehicle driving, running into the height point of a protrusion, vibration damper should be expressed to a minimum point to it in the time of will being subjected to outside impact force, because the defective of product itself can not be done this point, its reason is exactly that original product can not reach desirable vibration damping point position to hydraulic oil by pressure valve in moment, when vehicle driving to concave point, because wheel can fall to concave point fast, wheel and vehicle body distance widen, the drive vibration damper elongates, and makes to subtract to produce secondary high pressure in the device, can strengthen the impact force of vehicle body and wheel itself, what cause this existing reason is that hydraulic oil can not in time cover at all, and the reason that hydraulic oil can not be able to not the cover oversize institute that is the stroke of existing product piston extremely.It self rebounding force will strengthen, and can throw a higher height to vehicle, because the weight of itself has produced Vehicular vibration again unintentionally one time, so just allows vehicle lose due vibration damping protection.
[summary of the invention] the invention provides a kind of Oil-gas Separation ride-control for overcoming the above-mentioned defective of existing dydraulic shock absorber, to improve the effectiveness in vibration suppression of vibration damper, improves the smoothness of vehicle driving.
For solving its technical problem, the technological scheme that the present invention takes is: the present invention includes oil cylinder, piston rod and installation suspension ring, its feature is: be provided with a piston rod in the described oil cylinder, the bottom of this piston rod is provided with energy and subtracts and change valve, and the top of piston rod is passed guide sleeve and is connected with the oil cylinder top board and with last installation suspension ring; Piston rod is the cylindrical body of hollow seal, is provided with the portable air piston in the inner chamber of piston rod.Described piston rod is a hollow body, is provided with air bag between portable air piston rod in the bar and the masthead.
The invention has the beneficial effects as follows: 1. in an oil cylinder, be provided with a cylinder simultaneously because the present invention adopts, use earlier the oil cylinder vibration damping, when external force strengthens, with the air bag in the cylinder power absorption is got up again, by the transformation of energy valve vibrational energy is converted to heat energy during recovery.2. because the present invention adopts promptly removablely, can absorb again and the air compression piston rod of switching energy,, come timely vibration damping and energy storage and change can only passively become active damping and piston rod in the product in the past by moving.3. the present invention adopts oil cylinder and cylinder vibration damping, is equivalent to the coherent use of two-stage shock absorber, and vibration damping speed is fast, and is effective, also can be according to the vehicle needs, and two vibration dampers of the present invention of contacting, its effectiveness in vibration suppression can be better.That is: the impact force that is subjected to the road surface when wheel hour, it will utilize oil cylinder to come vibration damping, when vehicle is subjected to that self gravitation impacts or car load when affording up and down impact force, it will pass to these two kinds of power in the air bag in the mobile oil cylinder inner piston rod, carry out vibration damping with pressurized air, make vehicle safer, steadily, the rider is felt comfortably cool and environmental protection.4. this damper structure is simple, cheap, can be widely used on the various automobiles.5. because of the present invention being installed in can be free movable between wheel and the vehicle body, when operation, can reduce the striking force on wheel and ground greatly, can reduce vehicle resistance under steam, can reduce the oil consumption of vehicle operating, and can reduce the noise in the driving.
[description of drawings] the present invention is further described below in conjunction with accompanying drawing and example.
Fig. 1 is a structural representation sectional view of the present invention.
Fig. 2 is an A-A sectional view among Fig. 1.
Among the figure: suspension ring are installed, 2 piston rods, 3 air bags, 4 oil cylinders, 5 transformation of energy valves 6, portable air piston, 7, pilot valve, 8, down suspension ring are installed on 1.
[embodiment] is with reference to accompanying drawing, be provided with installing ring 8 down in the lower end of columnar oil cylinder 4, in the chamber of oil cylinder, be provided with a piston rod 2, this piston rod is a hollow body, and the bottom of hollow stem is provided with transformation of energy valve 5, is provided with air bag 3 in the cavity of piston rod, be provided with portable air piston 6 in this air bag, be provided with guide sleeve 7 at the top of oil cylinder 3, the cylinder body top board is stretched out after passing guide sleeve and oil sealing in the top of piston rod, and the piston rod top outside stretching out cylinder body is connected with installs suspension ring 1.During work, in oil cylinder, be filled with hydraulic oil, be filled with pressurized air in the piston rod, be installed in this vibration damper between the vehicle body of vehicle and the wheel axle after, just can be steady, safe travelled.
