Abstract
The invention discloses a damper with an automatic damping adjusting function, which belongs to the field of dampers. The damper comprises a cylinder body and a piston rod, wherein the inner wall of the cylinder body at least comprises a first cavity and a second cavity of which the diameters are different; a first piston and a second piston are connected in the first cavity in a sliding way; a third piston is connected to the second cavity in a sliding way; damping holes are formed in the first piston and the third piston; a first ventilation hole is formed in the first piston; a second ventilation hole is formed in the second piston; the projections of the damping hole formed in the first piston and the second ventilation hole formed in the second piston intersect with each other; an elastic component is arranged between the first piston and the second piston; the second piston is connected with the third piston through a connecting rod; and the piston rod is arranged on the first piston.
Description
Technical field
The present invention relates to vibration damper technical field, especially relate to the vibration damper that a kind of damping regulates automatically.
Background technique
Concussion when vibration damper rebounds after being mainly used to suppress spring shock-absorbing and the impact from road surface.Through uneven road surface, although shock-absorbing spring can filter the vibrations on road surface, spring self also has to-and-fro motion, and vibration damper is just used to suppress this spring to jump.Vibration damper relies on damping force to suppress the jump of spring.Damping force is too little, and vehicle body will vertical bounce, and damping force will bring too large resistance too greatly, hinders spring normally to work.
Traditional vibration damper mainly comprises cylinder body, piston is provided with in cylinder body, piston is fixed with piston rod, piston is also provided with damping hole, and both ends of the spring is separately fixed on piston rod and cylinder body, when automobile is given a shock, spring pressurized or tension, piston rod is also along with moving up and down, and during motion, piston is subject to larger resistance, slows down the jump of spring.The resistance that piston is subject to is determined by the size of damping hole, and damping hole once after shaping, its large minor matter is unalterable, also just causes the damping of vibration damper to regulate.
Summary of the invention
The present invention is directed to deficiency of the prior art, provide the vibration damper that a kind of damping regulates automatically, according to the size of vibrations, can automatically regulate the damping force of vibration damper.
For solving the problems of the technologies described above, the present invention is solved by following technical proposals: the vibration damper that damping regulates automatically, comprise cylinder body and piston rod, described inboard wall of cylinder block at least comprises the first different cavity of diameter and the second cavity, first piston and the second piston is slidably connected in described first cavity, the 3rd piston is slidably connected in described second cavity, described first piston and described 3rd piston are all provided with damping hole, described first piston is provided with the first vent, described second piston is provided with the second vent, the described damping hole that described first piston is arranged is crossing with the second vent projection in the horizontal plane that described second piston is arranged, elastic component is provided with between described first piston and described second piston, be connected by connecting rod between described second piston and described 3rd piston, described piston rod is arranged on described first piston.Vibration damper is operated in when not being the section of jolting very much, first piston and the second piston are separated from each other under the effect of elastic component, first piston and the second piston are owing to being provided with the first vent and the second vent, air-flow can pass through these two vent free flows, so now first piston and the second piston all do not play damping function, only have the 3rd piston to play damping function, damping force is not very large, avoids vibration damper to hinder the normal work of spring.When vibration damper is operated in the section of jolting, first piston and the second piston fit together due to the effect of impact force, first vent and the second vent all blocked, damping hole now on first piston also plays damping function, at this moment damping force increases greatly, avoid spring to recover too fast, cause the jump of vehicle.
In technique scheme, preferably, described first piston is provided with the first receiving groove, described second piston is provided with the second receiving groove, the two ends of described elastic component lay respectively in described first receiving groove and described second receiving groove.
In technique scheme, preferably, described elastic component is spring.
The invention has the beneficial effects as follows: vehicle operating on stable road surface time, the damping of vibration damper is very little, avoids vibration damper to hinder the normal work of spring.In vehicle operating when jolting road surface, the damping of vibration damper becomes large, avoids spring to recover too fast, causes the jump of vehicle.
Accompanying drawing explanation
Fig. 1 is the schematic diagram that vibration damper that damping regulates automatically is operated in smooth-riding surface.
Fig. 2 is the schematic diagram that vibration damper that damping regulates automatically is operated in road surface of jolting.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail: see Fig. 1, the vibration damper that damping regulates automatically, comprise cylinder body 1 and piston rod 2, inboard wall of cylinder block at least comprises the first different cavity 11 and the second cavity 12 of diameter, first piston 31 and the second piston 32 is slidably connected in first cavity 11, the 3rd piston 33 is slidably connected in second cavity 12, first piston 31 and the 3rd piston 33 are all provided with damping hole 311 and 331, first piston 31 is provided with the first vent 312, second piston 32 is provided with the second vent 321, the damping hole 311 that first piston 31 is arranged is crossing with the second vent 321 projection in the horizontal plane that the second piston 32 is arranged, spring 5 is provided with between first piston 31 and the second piston 32, first piston 31 is provided with the first receiving groove 3a, second piston 32 is provided with the second receiving groove 3b, spring 5 two ends lay respectively in the first receiving groove 3a and the second receiving groove 3b.Be connected by connecting rod 4 between second piston 32 and the 3rd piston 33, piston rod 2 is arranged on first piston 31.
See Fig. 1, vehicle travels when steady section, first piston and the second piston are separated from each other under the effect of elastic component, first piston and the second piston are owing to being provided with the first vent and the second vent, air-flow can pass through these two vent free flows, so now first piston and the second piston all do not play damping function, only has the 3rd piston to play damping function, damping force is not very large, avoids vibration damper to hinder the normal work of spring.
See Fig. 2, when vibration damper is operated in the section of jolting, first piston and the second piston fit together due to the effect of impact force, first vent and the second vent all blocked, damping hole now on first piston also plays damping function, at this moment damping force increases greatly, avoids spring to recover too fast, causes the jump of vehicle.
