Abstract
The utility model relates to a single-cylinder nitrogen damper which comprises a liquid storage tank, a gas storage tank connected with the liquid storage tank through an oil pipe and a piston rod inserted into the liquid storage tank through a piston valve. A partition plate piston is arranged inside the gas storage tank, one end of the gas storage tank is communicated with the oil pipe, and a nozzle is arranged in the other end of the gas storage tank. The gas storage tank is connected to the outside of the liquid storage tank and then connected with the liquid storage tank through the oil pipe, the movable piston is arranged inside the gas storage tank, the damping effect becomes poor due to the facts that when the damper works for a long time, the temperature rises and glutinousness of damping oil is weakened, namely damping oil is diluted, but on the contrary, the higher the temperature is, the higher the internal pressure of nitrogen becomes, the defect that damping oil is diluted can be compensated, damping force of the damper basically keeps constant in the whole process, and the application effect is particularly the most apparent on refitted vehicles and competitive vehicles.
Description
Technical field
The utility model relates to a kind of vibration damper, especially a kind of nitrogen single drum shock absorber.
Background technique
The work long hours viscosity of temperature rising damping oil of oil damp weakens (thinning) and causes damping effect variation, especially when high speed idle running is moved, has abnormal sound, therefore for to take advantage of the travelling comfort of driving to bring adverse effect.
Model utility content
Technical problem to be solved in the utility model is vibration damper high speed idle running abnormal sound, and a kind of nitrogen single drum shock absorber is provided.
For addressing the above problem, technical solution adopted in the utility model is: a kind of nitrogen single drum shock absorber, comprise liquid container, the gas holder being communicated with liquid container by oil pipe, by piston valve, be plugged on the piston rod in liquid container, described built in gas tank is equipped with dividing plate piston, and described gas holder one end the other end that is connected with oil pipe is provided with valve.
Furtherly, liquid container is provided with dust-proof cover in piston rod one end.
Furtherly, described valve is connected with onboard nitrogen supplier.
The beneficial effect that adopts technique scheme to produce is:
The utility model connects gas holder in the outside of liquid container, by oil pipe, connect again, facility movable piston in gas holder, in the work long hours viscosity of temperature rising damping oil of oil damp, weaken (thinning) and cause damping effect variation like this, yet increasing thereupon, the higher interior pressure of nitrogen temperature on the contrary can make up the thinning defect of damping oil, in whole process, the damping force of vibration damper keeps constant substantially, concerning the driver of automobile, there is no the discomfort what brings because damping effect changes, in especially can changing gas holder when different road conditions, thereby the pressure of nitrogen regulates the damping force of vibration damper to adapt to different road conditions and driving demand, especially in refitted car and sports vehicle, effect is the most obvious.
In senior compact car field, valve is directly connected with air feeder, the air inlet valve of giving vent to anger has middle control fingertip control, air pressure in gas holder is directly connected with hollow, when road conditions change, control system regulates the air pressure in gas holder automatically, also can there is driver directly to control the air pressure that gas holder does not have, so that the damping force of vibration damper looks like to mate with road conditions.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Wherein: 1 liquid container, 2 oil pipes, 3 gas holder, 4 piston valves, 5 piston rods, 6 dividing plate pistons, 7 valves, 8 dust-proof cover, 9 damping oils, 10 nitrogen, 11 piston valve adjusting knobs.
Embodiment
Below in conjunction with the drawings and specific embodiments, model utility is described in further detail:
A kind of nitrogen single drum shock absorber as shown in Figure 1, a kind of nitrogen single drum shock absorber, it is characterized in that: it comprises liquid container 1, the gas holder 3 being communicated with liquid container 1 by oil pipe 2, by piston valve 4, is plugged on the piston rod 5 in liquid container 1, in described gas holder 3, be provided with dividing plate piston 6, described gas holder 3 one end the other end that is connected with oil pipe 2 is provided with valve 7.
Liquid container 1 is provided with dust-proof cover 8 in piston rod 2 one end, can avoid like this impact of laying dust on system damping power.Described valve 7 is connected with onboard nitrogen supplier.
Piston valve 4, also referred to as orifice valve, is often used in vibration damper, and piston valve adjusting knob 11 is also normal quilt, and these are all the structures that vibration damper those skilled in the art know, and at this, do not repeat.
The utility model connects gas holder 3 in the outer end of liquid container 1, by oil pipe 2, connecting, facility movable piston in gas holder 3, it is dividing plate piston, vibration damper is when working long hours, damping oil temperature raises, (thinning) causes damping effect variation to cause the viscosity of damping oil to weaken, yet increasing thereupon, the higher interior pressure of nitrogen temperature on the contrary can make up the thinning defect of damping oil, in whole process, the damping force of vibration damper keeps constant substantially, concerning the driver of automobile, there is no the discomfort what brings because damping effect changes, in especially can changing gas holder when different road conditions, thereby the pressure of nitrogen regulates the damping force of vibration damper to adapt to different road conditions and driving demand, especially in refitted car and sports vehicle, effect is the most obvious.
In senior compact car field, valve 7 is directly connected with nitrogen gas supply device, air inlet give vent to anger valve by control fingertip control, barometric information in gas holder 3 is directly connected with middle control, when road conditions change, control system regulates the air pressure in gas holder 3 automatically, also can directly control the air pressure that gas holder 3 does not have by driver, so that the damping force of vibration damper looks like to mate with road conditions.
