Abstract
The utility model relates to the field of rear shock absorbers of motorcycles, electromobiles and the like, and particularly relates to an oil seal for a shock absorber. The oil seal for the shock absorber overcomes the defect that the oil seal for the shock absorber in the prior art easily leaks oil and is capable of reducing the oil leakage of the shock absorber and improving the wear resistance. The technical scheme of the utility model is that: the oil seal for the shock absorber comprises an oil seal body and an oil seal framework, wherein the oil seal framework is embedded in the oil seal body; the oil seal body is provided with a central hole; the inner side wall of the oil seal body is provided with a main lip opening and a secondary lip opening; and the outer side wall of the oil seal body is wave-shaped on a horizontal cross section.
Description
Technical field
The utility model relates to rear shock absorber fields such as motorcycle, storage battery car, and concrete is a kind of vibration damper oil sealing.
Background technique
Be equipped with in the vibration damper damping with oil, for preventing leakage of oil, be provided with oil sealing in the vibration damper, oil sealing between connecting rod and urceolus, vibration damper through the oil sealing passing shaft to defeating tight guide holder and cylinder barrel.Existing oil seal structure is as shown in Figure 1, and it mainly is made up of oil seal body 1 and oil tight skeleton 2, and oil tight skeleton is embedded in the oil seal body; Oil seal body is provided with center hole 3; The oil seal body madial wall is provided with main lip 4 and secondary lip 5, and common main lip is a plurality of, and secondary lip has only one.The outer side wall of the oil seal body of existing vibration damper oil sealing is the plane, and in movement process, being easier in the vibration damper flowed out along wall, and the design of complanation rub resistance not.
Summary of the invention
The utility model has been invented a kind of oil sealing that can reduce the vibration damper leakage of oil, improve wear resistance to the shortcoming of the easy leakage of oil of vibration damper oil sealing in the existing technology.
The above-mentioned technical problem of the utility model is able to implement through following technological scheme: a kind of vibration damper oil sealing; Comprise oil seal body and oil tight skeleton; Oil tight skeleton is embedded in the oil seal body; Oil seal body is provided with center hole, and the oil seal body madial wall is provided with main lip and secondary lip, and the outer side wall of described oil seal body is wave-like type on lateral cross section.The wall design of wave-like type can reduce the vibration damper leakage of oil, and has improved wear resistance.
As preferably, oil tight skeleton for perpendicular crotch shape, can be avoided secondary lip like this on lateral cross section, can increase the materials being fabricated of secondary lip thus, reduces stress concentrations, can protect the secondary lip of oil sealing position effectively, prevents leakage of oil, improves the oil sealing bulk life time.
In sum, the utility model compared with prior art has following advantage: the utility model is simple in structure, is easy to make.The wall of optimizing the outer side wall of oil seal body is a wave-like type, can reduce the vibration damper leakage of oil, and improve wear resistance.The perpendicular crotch shape of oil tight skeleton can effective secondary lip position, prevents leakage of oil, improves the oil sealing bulk life time.
