Compared with the prior art, by putting the combined oil sealing structure into the circular working cavity of the guide seat, the combined oil sealing structure can be provided with a good working environment, the deformation of the combined oil sealing structure can be reduced, the upper portion and the lower portion of the combined oil sealing structure can both be protected, the combined oil sealing structure can be protected from being damaged, and the abrasion of the combined oil sealing structure can be reduced. Due to the fact that the combined oil sealing structure is arranged inside the circular working cavity, the combined oil sealing structure is not affected by the assembly errors or external force to the sealing mouth, the service life of the combined oil sealing structure can be effectively prolonged eventually, the sealing performance of the automotive shock absorber can be improved, and the oil leakage phenomenon of the automotive shock absorber can be effectively controlled.
Description
Technical field
The utility model relates to vehicle shock absorber, and specifically, the utility model relates to a kind of combined oil seal structure of vehicle shock absorber.
Background technique
In automotive suspension, the Main Function of vibration damper is by the vibration of the to-and-fro motion generation damping force decay vehicle body of vibration damper and the vibration of inhibition wheel, improves run smoothness and the operational stability of vehicle.
At absorber designing with in making, how to control the concern that leakage of oil all is subject to the artificer all the time.The high-pressure aerated vibration damper of horizontal monotubular particularly, therefore it require the oil gas in the vibration damper active chamber to separate owing to being to be horizontally installed on the chassis of car, and vibration damper could work, the stability during the guarantee vehicle operation.And the single cylinder aerating shock absorber packing gland adopts the exoskeletal combined oil seal structure of full glue without spring, material adopts fluorine rubber, integral body forms type by the rubber mold pressing, the damper stiffness of this structure is poor, easily produce plastic deformation, cause sealing relatively poor, oil leakage phenomenon is more serious, and the sealing that solves this type of vibration damper is a very stubborn problem.
The model utility content
Technical problem to be solved in the utility model provides a kind of combined oil seal structure of vehicle shock absorber, with the purpose of the sealing that reaches the Effective Raise vibration damper, with the oil leakage phenomenon of control vibration damper.
In order to solve the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of combined oil seal structure of vehicle shock absorber, vibration damper comprises clutch release slave cylinder and guide holder, be provided with the annular working chamber of placing described combined oil sealing at described guide holder, be provided with the oil sealing catch in described clutch release slave cylinder, described combined oil sealing is clipped between guide holder and the oil sealing catch.
Described combined oil sealing comprises the first oil sealing and the second oil sealing, and the first oil sealing is connected on the inner peripheral surface of the second oil sealing, and the surface of contact between the first oil sealing and the second oil sealing is the curved surface with bending.
Inwall at described clutch release slave cylinder is provided with limited step, and described oil sealing catch is arranged on this limited step.
Between described guide holder and clutch release slave cylinder, be provided with O type circle.
The utility model adopts technique scheme; compared with prior art; combined oil sealing is put into the annular working chamber of guide holder; for combination oil seal provides a good working environment; reduce the distortion of oil sealing; make oil sealing all protected up and down; the protection oil sealing is without prejudice; reduce wearing and tearing; and oil sealing is placed in the annular working chamber, is not subjected to the impact of assembly error, sealing external force, finally can effectively prolong the life-span of oil sealing; improve the sealability of vibration damper, effectively control the damper leakage phenomenon.
