Embodiment Construction

[0009] Such as figure 1 As shown, a new electric wheel hub motor oil seal according to the present invention is composed of a rubber compound lip 1, a metal skeleton 2 and a hoop spring 3, and the metal skeleton 2 is closely bonded to the rubber compound lip 1 through vulcanization. The hoop spring 3 is installed in the spring groove of the rubber compound lip 1. Grease is filled between the rubber compound lips 1 . The outermost dustproof lip of the rubber compound lip 1 is designed as a centrifugal structure.

[0010] The basic principles, main features and advantages of the present invention have been shown and described above. Those skilled in the industry should understand that the present invention is not limited by the above-mentioned embodiments. What are described in the above-mentioned embodiments and the description only illustrate the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention wi...

Abstract

The invention discloses a novel hub motor oil seal of an electric vehicle. The novel hub motor oil seal comprises a rubber double lip, a metal framework and a tightening spring, wherein the metal framework is tightly bonded with the rubber double lip through sulfuration, and the tightening spring is installed in a spring groove of the rubber double lip. Lubricating grease is added between the rubber double lip. A dust-proof lip at the outermost end of the rubber double lip is in an exocentric structure. The novel hub motor oil seal of the electric vehicle has the advantages that the structure is simple, producing costs are low, and functions of high protecting capacity against foreign matters, low working temperature and energy consumption of bearings and small friction torque of a seal lip can be achieved.

Description

technical field [0001] The invention belongs to the technical field of wheel hub motor oil seals, and relates to a novel electric wheel hub motor oil seal. Background technique [0002] At present, 80% of the failure of the electric wheel hub motor is due to the failure of the dustproof function of the hub motor oil seal itself, which causes sand to enter the motor bearing and cause the bearing to fail. As the market has higher and higher requirements for the life of electric vehicles, direct The reliability of the motor oil seal of the hub motor is required within the specified three-guarantee period, which directly requires the motor oil seal to improve its life under the condition of dust-proof and mud-proof functions. Under such conditions, oil seal manufacturers have also improved the product structure on the basis of the original oil seal structure, adding a dust-proof seal structure. Although the performance requirements for dust-proof and mud-proof performance of the...
