Abstract
The utility model provides novel shock-absorbing device and relates to the manufacturing field of automobiles. The shock-absorbing device comprises a casing, an oil cylinder, a piston shaft, a bottom valve, a guide bearing, an oil sealing base, a piston and an elastic component, wherein the casing and the oil cylinder are coaxial, the bottom valve is arranged at the bottom of the oil cylinder, the piston is arranged at the lower end of the piston shaft, the guide bearing is sleeved on the piston shaft, the lower portion of the guide bearing is in interference fit with the oil cylinder, the upper portion of the guide bearing is in interference fit with the casing, the oil sealing base is arrange on the upper portion of the guide bearing and is in interference fit with the casing, and the elastic component is sleeved on the upper portion of the piston shaft and is in interference fit with the piston shaft. By the aid of the shock-absorbing device, the elastic component is arranged on the outer side of the casing and sleeved on the piston shaft, so that the elastic component can reduce the shock of an automobile and enhance the shock-absorbing effect.
Description
Technical field
The utility model relates to automobile manufacturing field, is specifically related to damping device.
Background technique
Damping device is one of the important component part on the chassis of automobile.The quality of its quality directly affects smoothness, the travelling comfort that car load goes.Although the suspension of Hyundai Motor has various structural type, generally constitute by elastic element, damping device and guide mechanism three parts, wherein, damping device is the most accurate parts.But the shockproof effect of existing damping device is unsatisfactory; The leakage of oil problem happens occasionally, main cause be in-oil cylinder oil when pressure is big, be penetrated into the oil sealing base place easily, cause the oil sealing base leakage of oil, thereby make automobile shock-absorber lose the function of damping.In addition, since coaxial and unstable between oil cylinder and the piston shaft, so also cause the instability on the performance easily.
The model utility content
The purpose of the utility model provides a kind of novel damping device, can strengthen damping effect.
The utility model provides a kind of novel damping device, comprises shell, oil cylinder, piston shaft, bottom valve, guide bearing, oil sealing base and piston, and said shell is coaxial with oil cylinder; The bottom of said oil cylinder is provided with bottom valve; Said piston shaft lower end is provided with piston, and said guide bearing is sheathed on the piston shaft, the bottom of this guide bearing and oil cylinder interference fit, top and shell interference fit; The top of this guide bearing is provided with oil sealing base; This oil sealing base and shell interference fit, said damping device also comprise an elastic member, this elastic member be sheathed on piston shaft top, with the piston shaft interference fit.
Said damping device also comprises the collar that is provided with a plurality of through holes, and the said collar is enclosed within on the bottom valve, is positioned at bottom valve and oil cylinder joint, with the oil cylinder interference fit.
Said guide bearing is provided with the leakage of oil passage, and an end of this leakage of oil passage communicates with the center hole of said guide bearing, and the other end of this leakage of oil passage communicates with cavity between oil cylinder and the shell.
The novel damping device that adopts the utility model to provide because elastic member is positioned at the outside of shell, is sheathed on the piston shaft, so this elastic member can alleviate the vibrations of automobile, strengthens damping effect.Because the existence of leakage of oil passage can import the cavity between shell and the oil cylinder from this passage with too much fluid, thereby reduces pressure, the situation of leakage of oil.In addition because the existence of the collar, can guarantee between piston shaft and the oil cylinder coaxial, thereby make the service behaviour of damping device more stable.
Description of drawings
Fig. 1 is the structure diagram of the utility model, 1-piston shaft wherein, 2-oil sealing base, 3-guide bearing, 4-shell, 5-oil cylinder, 6-piston, 7-bottom valve, 8-collar, 9-leakage of oil passage, 10-elastic member.
Embodiment
The concrete structure of embodiment's 1 the utility model
The utility model provides a kind of novel damping device, comprises shell 4, oil cylinder 5, piston shaft 6, bottom valve 7, guide bearing 3, oil sealing base 2 and piston 6, and said shell 4 is coaxial with oil cylinder 5; The bottom of said oil cylinder 5 is provided with bottom valve 7; Said piston shaft 1 lower end is provided with piston 6, and said guide bearing 3 is sheathed on the piston shaft 1, the bottom of this guide bearing 3 and oil cylinder 5 interference fit, top and shell 4 interference fit; The top of this guide bearing 3 is provided with oil sealing base 2; This oil sealing base 2 and shell 4 interference fit, said damping device also comprises an elastic member 10, this elastic member 10 be sheathed on piston shaft 1 top, with piston shaft 1 interference fit.The material of this elastic member can be spring or rubber.
Said guide bearing 3 is provided with leakage of oil passage 9, and an end of this leakage of oil passage 9 communicates with the center hole of said guide bearing 3, and the other end of this leakage of oil passage 9 communicates with cavity between oil cylinder 5 and the shell 4.
Said damping device also comprises the collar 8 that is provided with a plurality of through holes, and the said collar 8 is enclosed within on the bottom valve 7, is positioned at bottom valve 7 and oil cylinder 5 joints, with oil cylinder 5 interference fit.
The novel damping device that adopts the utility model to provide because elastic member is positioned at the outside of shell, is sheathed on the piston shaft, so this elastic member can alleviate the vibrations of automobile, strengthens damping effect.Because the existence of leakage of oil passage can import the cavity between shell and the oil cylinder from this passage with too much fluid, thereby reduces pressure, the situation of leakage of oil.In addition because the existence of the collar, can guarantee between piston shaft and the oil cylinder coaxial, thereby make the service behaviour of damping device more stable.
