Abstract
The utility model relates to a sealing piece, in particular to a front axle oil seal comprising an inner oil seal, an outer framework and an inner sealing ring which are combined mutually, wherein the inner oil seal consists of an inner framework, an inner sealing body and a spring; the inner sealing ring is arranged in the outer framework; and an inner sealing body of the inner oil seal has a bidirectional sealing lip structure and is provided with two springs which respectively form a radial holding structure with the bidirectional sealing lip structure. The front axle oil seal has the advantages of being convenient to install and use and meeting sealing requirements, can well meet the requirement that lubrication media of a lubrication system do not escape or leak, can well ensure that external muddy water does not enter the lubrication system, can ensure the normal use of a vehicle, and can meet the requirements of actual conditions.
Description
Technical field
The utility model relates to a kind of Sealing, especially a kind of propons oil sealing.
Background technique
The oil sealing at propons position, should guarantee that lubricant medium do not reveal, satisfy the lubricated proper functioning of system, seal the silt that exists in the Environmental Conditions again, impurity such as water, avoid it to enter lubrication system, and present propons oil sealing, the lubricant medium that how can't well satisfy lubrication system does not leak or seepage, can not guarantee well that outside muddy water does not enter lubrication system, be difficult to guarantee the normal use of vehicle, for this reason, need a kind of lubricant medium that can well satisfy lubrication system not leak or seepage, simultaneously can guarantee well that outside muddy water does not enter lubrication system, can guarantee the propons oil sealing of the normal use of vehicle, satisfy the needs of actual conditions with this.
The model utility content
Propons oil sealing of the present utility model, it has advantage easy to install and that satisfy seal request, its lubricant medium that can well satisfy lubrication system does not leak or seepage, simultaneously can guarantee well that outside muddy water does not enter lubrication system, the normal use of vehicle can be guaranteed, the needs of actual conditions can be satisfied.
The technological scheme that the utility model adopted is:
The propons oil sealing is characterized in that: comprise the inner oil seal of mutual combination, outer skeleton and inner seal ring, inner oil seal is made up of inner frame, interior seal and spring, and inner seal ring is arranged in the outer skeleton.
Described propons oil sealing, the interior seal of inner oil seal is made as two way sealed lip structure, and is provided with two springs and forms with two way sealed lip structure respectively and radially hold structure tightly.
When work, propons oil sealing of the present utility model is provided with inner seal ring in its outer skeleton like this, and inner seal ring mainly plays the dust-tight effect; The interior seal of inner oil seal is made as two way sealed lip structure, and be provided with two springs and radially hold structure tightly with the formation of two way sealed lip structure respectively, can increase sealability, one side sealing lip plays the effect of oil sealing, opposite side seal lip plays the effect of envelope foreign matter, and the inner frame of inner oil seal plays the effect of support.
Propons oil sealing of the present utility model, it has advantage easy to install and that satisfy seal request, its lubricant medium that can well satisfy lubrication system does not leak or seepage, simultaneously can guarantee well that outside muddy water does not enter lubrication system, the normal use of vehicle can be guaranteed, the needs of actual conditions can be satisfied.
