Abstract
The utility model relates to a short stroke inflatable bumper shock absorber for high speed train. It includes an oil storage section of thick bamboo and piston rod, and oil storage section of thick bamboo one end has first bobbin base and links there is first go -between, and the oil storage section of thick bamboo other end has the closing cap just. There are piston cylinder and the two to leave the interval in the oil storage section of thick bamboo. The both ends of piston cylinder are balanced with the first bobbin base and the closing cap of an oil storage section of thick bamboo respectively. There is a pole hole at the closing cap center, and the parallel connection had the piston in the piston cylinder was stretched into through the pole hole in the piston rod inner end, and there is the second go -between piston rod outer end. Its characteristics are that the piston rod outside has the dust cover, and this dust cover is cylindric, and its one end has the second bobbin base, and the second bobbin base lies in between the neighboring terminal of second go -between and piston rod. The internal diameter of dust cover is greater than the external diameter of an oil storage section of thick bamboo. Adopt the utility model discloses, can avoid the defective shock absorber, make high speed train operation in -process take place to jolt and the discomfort brought for the passenger. Can be used for reducing the go vibration amplitude of in -process of high speed train.
Description
Technical field
The utility model relates to a kind of train vibration damper.Specifically, the short stroke air filling type shock absorber reducing vibration amplitude in bullet train running process is used to.
Background technique
All knowing at bullet train production field, for reducing bullet train vibration amplitude in the process of moving, bullet train being all provided with short stroke air filling type shock absorber.This short stroke air filling type shock absorber comprises oil storage cylinder and piston rod, and at the bottom of one end of described oil storage cylinder has tin and the first connecting ring be connected with for being connected with compartment in the mounted state, the other end of oil storage cylinder has capping and coordinates in sealing shape between the two.There is piston cylinder in oil storage cylinder and leave spacing between the two.The two ends of piston cylinder respectively with at the bottom of the cylinder of oil storage cylinder and capping offset.Described cap central has rod aperture, and described piston rod inner end to be stretched in piston cylinder by rod aperture and is connected with piston, and there is the second connecting ring for being connected with bogie in the mounted state piston rod outer end.
The piston rod being only connected with piston by the piston cylinder in oil storage cylinder, oil storage cylinder and one end due to this short stroke air filling type shock absorber is formed, without dust prevention, in bullet train running process, corrosive material in rainwater, mud and air can damage the sealing between piston rod and oil storage cylinder, time serious, can defective shock absorber be caused, make to jolt in bullet train running, bring discomfort to passenger.
Model utility content
Problem to be solved in the utility model is to provide a kind of bullet train short stroke air filling type shock absorber.The discomfort adopting this bullet train short stroke air filling type shock absorber, defective shock absorber can be avoided, make to jolt in bullet train running and bring to passenger.
The problems referred to above to be solved in the utility model are realized by following technological scheme:
Bullet train short stroke air filling type shock absorber of the present utility model comprises oil storage cylinder and piston rod, one end of described oil storage cylinder to have at the bottom of first and the first connecting ring be connected with for being connected with compartment in the mounted state, and the other end of oil storage cylinder has capping and coordinates in sealing shape between the two.There is piston cylinder in oil storage cylinder and leave spacing between the two.The two ends of piston cylinder respectively with at the bottom of first of oil storage cylinder and capping offset.Described cap central has rod aperture, and described piston rod inner end to be stretched in piston cylinder by rod aperture and is connected with piston, and there is the second connecting ring for being connected with bogie in the mounted state piston rod outer end.Be characterized in there is dust-proof cover outside described piston rod, this dust-proof cover comprises cylinder, and cylinder one end has at the bottom of second, at the bottom of second between the second connecting ring and the neighboring terminal of piston rod.The internal diameter of described dust-proof cover is greater than the external diameter of oil storage cylinder.
Wherein, the length of described dust-proof cover is not less than the length of piston rod.
As can be seen from the above scheme, owing to taking dust prevention by arranging dust-proof cover outside described piston rod, thus avoid the destruction of being caused by the corrosive goods confrontation piston rod in rainwater, mud and air and the sealing between oil storage cylinder in bullet train running process, avoid defective shock absorber and the situation of jolting in bullet train running is occurred, bringing comfortable feel to passenger.
Accompanying drawing explanation
Fig. 1 is bullet train short stroke air filling type shock absorber structural representation of the present utility model.
Embodiment
As shown in Figure 1, bullet train short stroke air filling type shock absorber of the present utility model comprises oil storage cylinder 5 and piston rod 2, one end of described oil storage cylinder 5 to be processed with at the bottom of first at the bottom of 8, first the first connecting ring 9 be welded with outside 8 for being connected with compartment in the mounted state.The other end of oil storage cylinder 5 is provided with capping 11, and capping 11 inner circle and cylindrical are all processed with peripheral groove, is all provided with seal ring 4 in peripheral groove, and capping 11 is all coordinated in sealing shape with between oil storage cylinder 5 surrounding and piston rod 2.Be provided with piston cylinder 10 in oil storage cylinder 5, the external diameter of piston cylinder 10 is less than the internal diameter of oil storage cylinder 5, makes to leave spacing between piston cylinder 10 and oil storage cylinder 5.Wherein, the two ends of piston cylinder 10 respectively with at the bottom of first of oil storage cylinder 58 and capping 11 offset.Described capping 11 center is processed with rod aperture, and described piston rod 2 inner end is that slip shape stretches in piston cylinder 10 through after rod aperture, and piston rod 2 one end stretched in piston cylinder 10 is connected with piston 7.The excircle of piston 7, to being processed with groove, is provided with seal ring 4 in groove.Piston rod 2 outer end is welded with the second connecting ring 1 for being connected with the bogie of bullet train in the mounted state.For avoiding being damaged by the corrosive goods confrontation piston rod 2 in rainwater, mud and air and the sealing between oil storage cylinder 5 in bullet train running process, until make defective shock absorber and make jolt in bullet train running and bring discomfort to passenger, dust-proof cover is provided with outside described piston rod 2, this dust-proof cover comprises cylinder 6, cylinder 6 one end to be processed with at the bottom of second at the bottom of 3, second 3 between the second connecting ring 1 and the neighboring terminal of piston rod 2.The internal diameter of described cylinder 6 is greater than the external diameter of oil storage cylinder 5.The length of described cylinder 6 is not less than the length of piston rod 2.
