Abstract
The utility model solves a kind of novel electric vehicle wheel hub motor oil sealing, is made up of rubber dicheilia, metal frame and lock ring spring, and described metal frame is by sulfuration and rubber dicheilia tight bond, and lock ring spring fitting is in the spring groove of rubber dicheilia.Repack with grease between described rubber dicheilia.The outermost end dust excluder lips of described rubber dicheilia is designed to exocentric structure.The utlity model has the advantages such as simple in structure and cheap, can realize that foreign matter protective ability is high, the operating temperature of bearing and energy consumption is low and sealing lip friction torque is little function.
Description
Technical field
The utility model belongs to wheel hub motor oil seal technique field, relates to a kind of novel electric vehicle wheel hub motor oil sealing.
Background technique
At present, in wheel hub electric motor of electric vehicle failure procedure, 80% reason is to cause bearing failure because the inefficacy of wheel hub motor oil sealing self dust reduction capability causes silt to enter motor bearings, along with market is more and more higher to electric motor car life requirements, directly require wheel hub motor reliability of electric engine oil seal within the three guarantees phase of regulation, this just directly requires electric engine oil seal to improve the life-span in the situation that of dustproof, anti-muddy water function.Under this condition, oil sealing producer has also carried out product structure improvement on the architecture basics of original oil sealing, has increased dust seal structure, although improve the performance requirement of dustproof, the anti-muddy water of sealing system, increases by 1 times of above director costs simultaneously.Therefore, existing technology can not meet actual usage requirement, in the urgent need to a kind of dustproof, anti-muddy water ability is high, selflubricating ability is good and life and reliability oil sealing is high wheel hub electric motor of electric vehicle oil seal structure.
Summary of the invention
The problem existing in order to solve above-mentioned prior art, the utility model provides a kind of novel electric vehicle wheel hub motor oil sealing, can realize that dustproof, anti-muddy water ability is high, selflubricating ability is good and the high function of life and reliability oil sealing.
The utility model solves the technological scheme that its technical problem adopts: a kind of novel electric vehicle wheel hub motor oil sealing, formed by rubber dicheilia, metal frame and lock ring spring, described metal frame is by sulfuration and rubber dicheilia tight bond, and lock ring spring fitting is in the spring groove of rubber dicheilia.Repack with grease between described rubber dicheilia.The outermost end dust excluder lips of described rubber dicheilia is designed to exocentric structure.
The beneficial effects of the utility model are: a kind of novel electric vehicle wheel hub motor oil sealing, there is the advantages such as simple in structure and cheap, and can realize that foreign matter protective ability is high, the operating temperature of bearing and energy consumption is low and sealing lip friction torque is little function.
Brief description of the drawings
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present utility model.
In figure 1, rubber dicheilia, 2, metal frame, 3, lock ring spring.
Embodiment
