Abstract
The utility model discloses an oil pressure vibration absorber including that: an oil storing cylinder is internally sleeved with a pressure cylinder that is internally provided with a piston; the piston is connected with a piston rod and is provided with a single way valve; the lower part of the pressure cylinder is provided with a single way oil inlet bottom valve, while the upper part is provided with a cylinder end body; the cylinder end body is internally provided with a throttle and an unloading valve which are both communicated with the pressure cylinder and the oil storing cylinder; and the upper part of the cylinder end body is provided with a following sealing part. The utility model has the advantages of a reasonable structure and good vibration performance; besides, the flute has a simple structure and easy to process and position.
Description
The utility model relates to a kind of vibration damping equipment, the oil-pressure damper that particularly a kind of rail vehicles is used.
Existing rail vehicles oil-pressure damper, owing to reasons such as structures, sealing effect is undesirable, and Sealing is easy to wear, and damping property can not satisfy the requirement of rolling stock.
The purpose of this utility model is to provide a kind of rational in infrastructure, oil-pressure damper that damping property is good.
Technical solution of the present utility model is:
A kind of oil-pressure damper, suit pressure cylinder in the oil storage cylinder, dress piston in the pressure cylinder, piston connects piston rod, and one-way valve is housed on the piston, and unidirectional oil-feed bottom valve is adorned in the pressure cylinder bottom, the difference of itself and prior art is: pressure cylinder top dress cylinder end body, dress throttle valve and unloading valve in the cylinder end body, throttle valve and unloading valve all are communicated with pressure cylinder and oil storage cylinder, cylinder end body top dress Follow-up seal spare.
Follow-up seal spare comprises the blind nut that is loaded on cylinder end body top, and the bellows follower is connected with blind nut, the seal ring that dress contacts with piston rod on the bellows follower, dress follower limited cover on the blind nut.The dust ring that dress contacts with piston rod on the bellows follower.The seal ring that dress contacts with piston rod on the cylinder end body.The guiding plastics slip ring that dress contacts with piston rod on the cylinder end body.At the outside dress of pressure cylinder heat dissipating housing.
The utility model is rational in infrastructure, and damping property is good; Groove structure is simple, processing, simple installation; High pressure resistant, operating conditions adaptability is strong; Adopt unique upper end throttling, the structure that the off-load regulating system matches with the insurance sealing of servo-actuated form, when throttling and off-load, fluid directly flows into outer oil cavity from the pressure cylinder upper end, reduced the sealing interior oil pocket pressure that friction pair bore in first road between the bar oil, thereby strengthened the sealability of the first road bar oil, the Follow-up seal form is adopted in the insurance sealing of second road between the bar oil, make vibration damper under the general high frequency situation that antivibration moves by a narrow margin, the servo-actuated of insurance Sealing with the to-and-fro motion of piston rod, do not produce relative movement, thereby reduced the wearing and tearing of Sealing, and prolonged the working life of Sealing, increased the safety of Follow-up seal.Increased heat dissipating housing in the pressure cylinder outside, when making inner chamber fluid flow into outer oil cavity, the fluid heat dissipating housing outer wall of flowing through, the fluid heat is dispersed into the vibration damper outside through the oil storage cylinder inwall, thereby guarantees the cooling fast and effectively of circulation fluid.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is an embodiment's of the utility model a configuration diagram.
Fig. 2 is the partial enlarged drawing of Fig. 1.
A kind of oil-pressure damper, suit pressure cylinder 2 in the oil storage cylinder 1, dress piston 3 in the pressure cylinder 2, on the piston 3 one-way valve is housed, piston 3 connects piston rod 4, and unidirectional oil-feed bottom valve 5 is adorned in pressure cylinder 2 bottoms, pressure cylinder 2 tops dress cylinder end body 6, adorn adjustable throttle valve 7 and adjustable unloading valve 8 in the cylinder end body 6, throttle valve 7 and unloading valve 8 all are communicated with pressure cylinder 2 and oil storage cylinder 1, cylinder end body 6 tops dress Follow-up seal spare.
Follow-up seal spare comprises the blind nut 9 that is loaded on cylinder end body 6 tops, bellows follower 10 is connected with blind nut 9, the special envelope 11 of this that dress contacts with piston rod 4 on the bellows follower 10, dress follower limited cover 12 on the blind nut 9, the dust ring 13 that dress contacts with piston rod 4 on the bellows follower 10, the below dress sealing gasket 17 of bellows follower 10.The special envelope 16 of this that dress contacts with piston rod 4 on the cylinder end body 6, the guiding plastics slip ring 14 that dress contacts with piston rod 4 on the cylinder end body 6 is at pressure cylinder 2 outside dress heat dissipating housings 15.
