Abstract
The utility model relates to a cylinder for hydraulic shock absorber of motorcycles which comprises essentially a piston rod 1, an outer cylinder 4, an inner cylinder 12, a guide seat 10, oil seals 7 and 5, an oil return seat 15, a piston 16, a bottom valve seat 18, a seal ring 9, an oil-returning and pressure relief groove 19 and a dustproof oil seal 2. The utility model is characterized in that: A. A seal ring 9 is positioned inside the guide seat 10 by being embedded in the guide seat 10 and sleeved on the piston rod 1; B. The oil-returning and pressure-relief groove 19 is positioned above the guide seat 10. The utility mode has the advantages of good seal performance, no oil leakage, satisfying shock absorbing performance and long service life.
Description
One, technical field:
The utility model relates to a kind of motorcycle vibration absorber, especially a kind of motorcycle hydraulic bumper oil cylinder.
Two, background technology:
At present, the oil cylinder part of motorcycle vibration absorber is mainly by piston rod, interior outer cylinder body, guide holder, oil sealing, the oil return seat, composition such as piston and foot valve seat, piston is fixed on the piston rod, and be provided with the oil return seat thereon, foot valve seat is fixed on an end of inner cylinder body, the other end of inner cylinder body is fixed on the guide holder, oil sealing is arranged in outer cylinder body and is enclosed within on the piston rod, because oil sealing is the oil proof rubber elasticity oil sealing of simple structure, bumper is after the process long-term work, oil sealing damages easily and causes leakage of oil, and dust is brought in the oil cylinder with piston rod easily, thereby accelerated the oil sealed damage, causes this bumper oil spill rate height, damping performance is poor, and service life is short.
Three, summary of the invention:
The purpose of this utility model provides a kind of good seal performance, oil tight motorcycle hydraulic bumper oil cylinder.
The technical solution of the utility model is: a kind of motorcycle hydraulic bumper oil cylinder, comprise piston rod, outer cylinder body, inner cylinder body, guide holder, oil sealing, oil return seat, piston and foot valve seat, wherein piston is fixed on of piston rod, and be provided with the oil return seat thereon, foot valve seat is fixed on an end of inner cylinder body, the other end of inner cylinder body is fixed on the guide holder, oil sealing is arranged in outer cylinder body and is enclosed within on the piston rod, it is characterized in that: A is provided with seal ring in guide holder, and seal ring embeds guide holder and is enclosed within on the piston rod; B is provided with the oil return relief groove above guide holder.
Therefore seal ring is arranged in guide holder in the utility model, can increase the sealing property of bumper oil cylinder, the oil return relief groove is set on guide holder, reducing the pressure that acts on when the oil return on the oil sealing, thereby help the oil sealed sealing.
In the utility model another oil sealing can be arranged above the outer cylinder body inner oil seal, all be packaged with the cold-rolling steel steelframe in two oil sealings; In the oil sealing outside oil sealing metal level and dust laying oil capping are arranged, this dust laying oil capping is sleeved on the piston rod, is close to outside the oil sealing metal level, and outwards protrude at the middle part, closes on piston rod.
The utility model has the advantages that: good seal performance, oil tight, damping performance good, long service life.
Four, description of drawings:
Fig. 1 is the utility model structural representation.
Five, the specific embodiment:
Please see Figure 1: the utility model is by piston rod 1, dust laying oil capping 2, oil sealing metal level 3, outer cylinder body 4, oil sealing 5, oil sealing 7, cold-rolling steel steelframe 6, cold-rolling steel steelframe 8, seal ring 9, guide holder 10, oil cylinder exocoel 11, inner cylinder body 12, cylinder cavity 13, spring 14, oil return seat 15, piston 16, primary nut 17, foot valve seat 18 and oil return relief groove 19 are formed, wherein piston 16 is fixed on of piston rod 1, and be provided with oil return seat 15 thereon, foot valve seat 18 is fixed on an end of inner cylinder body 12, the other end of inner cylinder body 12 is fixed on the guide holder 10, oil sealing 7 is arranged in outer cylinder body 4 and is enclosed within on the piston rod 1, outer cylinder body 4 forms oil cylinder mistress 11 with inner cylinder body 12, inner cylinder body 12, guide holder 10 and foot valve seat 18 form oil cylinder inner room 13, it is characterized in that: A is provided with seal ring 9 in guide holder 10, and seal ring 9 embeds guide holder 10 and is enclosed within on the piston rod 1; B is provided with oil return relief groove 19 above guide holder 10.
It can also be seen that from Fig. 1: above outer cylinder body 4 inner oil seals 7, also have an oil sealing 5, be packaged with cold-rolling steel steelframe 6,8 in the oil sealing 5,7 respectively; In oil sealing 5 outsides oil sealing metal level 3 and dust laying oil capping 2 are arranged, this dust laying oil capping 2 is sleeved on the piston rod 1, is close to outside the oil sealing metal level 3, and outwards protrude at the middle part, closes on piston rod 1.
Therefore seal ring 9 is arranged in guide holder 10 in the utility model, can increase the sealing property of bumper oil cylinder, above guide holder 10, be provided with oil return relief groove 19, reducing the pressure that acts on when the oil return on the oil sealing 7, thereby help the sealing of oil sealing 7; Two oil sealings 7,5 are set in outer cylinder body 4, and in oil sealing, encapsulate the cold-rolling steel steelframe, help sealing and damping; Be outside equipped with oil sealing metal level 3 and dust laying oil capping 2 at oil sealing, can avoid dust to bring oil cylinder into piston rod 1 and destroy oil sealing, and then improve motorcycle hydraulic bumper sealing property, prevent leakage of oil, make it have good damping property, also increase service life.
