Description
Technical field
The present invention relates to the vibration damper technical field, especially relate to the vibration damper that a kind of damping is regulated automatically.
Background technique
Concussion when vibration damper is mainly used to suppress bounce-back after the spring shock-absorbing and from the impact on road surface.Through uneven road surface the time, although the shock-absorbing spring can filter the vibrations on road surface, spring self also has to-and-fro motion, and vibration damper is used for suppressing this spring jump.Vibration damper relies on damping force to suppress the jump of spring.Damping force is too little, and vehicle body will jump up and down, and damping force will be brought too large resistance too greatly, hinders the spring normal operation.
Traditional vibration damper mainly comprises cylinder body, be provided with piston in the cylinder body, be fixed with piston rod on the piston, also be provided with damping hole on the piston, both ends of the spring is separately fixed on piston rod and the cylinder body, when automobile is given a shock, spring pressurized or tension, also along with moving up and down, piston is subject to larger resistance to piston rod during motion, slows down the jump of spring.The resistance that piston is subject to determines by the size of damping hole, in case and after the moulding of damping hole, its large minor matter is unalterable, also just cause the damping of vibration damper to regulate.
Summary of the invention
The present invention is directed to deficiency of the prior art, the vibration damper that provides a kind of damping automatically to regulate can be according to the size of vibrations, the damping force of automatically regulating 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 is regulated automatically, comprise cylinder body and piston rod, described inboard wall of cylinder block comprises the first cavity and the second cavity that diameter is different at least, slidely connect first piston and the second piston in described the first cavity, slidely connect the 3rd piston in described the second cavity, all be provided with damping hole on described first piston and described the 3rd piston, be provided with the first vent on the described first piston, be provided with the second vent on described the second piston, the projection of the second vent on horizontal plane that arranges on the described damping hole that arranges on the described first piston and described the second piston intersected, be provided with elastic component between described first piston and described the second piston, link to each other by connecting rod between described the second piston and described the 3rd piston, described piston rod is arranged on the described first piston.When vibration damper is operated in the highway section that is not to jolt 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 this moment, first piston and the second piston did not all 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 operation of spring.When vibration damper is operated in the highway section of jolting, first piston and the second piston are owing to the effect of impact force fits together, the first vent and the second vent are all blocked, damping hole on the first piston also plays damping function at this moment, at this moment damping force increases greatly, avoid spring to recover too fast, cause the jump of vehicle.
In the technique scheme, preferred, be provided with the first receiving groove on the described first piston, be provided with the second receiving groove on described the second piston, the two ends of described elastic component lay respectively in described the first receiving groove and described the second receiving groove.
In the technique scheme, preferred, described elastic component is spring.
The invention has the beneficial effects as follows: during on road surface stably, the damping of vibration damper is very little, avoids vibration damper to hinder the normal operation of spring in vehicle operating.When jolting the road surface, it is large that the damping of vibration damper becomes in vehicle operating, avoids spring to recover too fast, causes the jump of vehicle.
Description of drawings
Fig. 1 is the schematic diagram that the automatic vibration damper of regulating of damping is operated in the smooth-riding surface.
Fig. 2 is the schematic diagram that the automatic vibration damper of regulating of damping is operated in the road surface of jolting.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail: referring to Fig. 1, the vibration damper that damping is regulated automatically, comprise cylinder body 1 and piston rod 2, inboard wall of cylinder block comprises the first cavity 11 and the second cavity 12 that diameter is different at least, slidely connect first piston 31 and the second piston 32 in the first cavity 11, slidely connect the 3rd piston 33 in the second cavity 12, all be provided with damping hole 311 and 331 on first piston 31 and the 3rd piston 33, be provided with the first vent 312 on the first piston 31, be provided with the second vent 321 on the second piston 32, the second projection of vent 321 on horizontal plane that arranges on the damping hole 311 that arranges on the first piston 31 and the second piston 32 intersected, be provided with spring 5 between first piston 31 and the second piston 32, be provided with the first receiving groove 3a on the first piston 31, be provided with the second receiving groove 3b on the second piston 32, spring 5 two ends lay respectively in the first receiving groove 3a and the second receiving groove 3b.Link to each other by connecting rod 4 between the second piston 32 and the 3rd piston 33, piston rod 2 is arranged on the first piston 31.
Referring to Fig. 1, Vehicle Driving Cycle is when steady highway 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 this moment, first piston and the second piston did not all 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 operation of spring.
Referring to Fig. 2, when vibration damper is operated in the highway section of jolting, first piston and the second piston are owing to the effect of impact force fits together, the first vent and the second vent are all blocked, damping hole on the first piston also plays damping function at this moment, at this moment damping force increases greatly, avoids spring to recover too fast, causes the jump of vehicle.
