SEALING STRUCTURE, INNER WHEEL DRIVE SYSTEM AND ASSEMBLY METHOD
20250141297 · 2025-05-01 ·

A sealing structure, an inner wheel drive system and a method for assembling a dustproof member in a sealing structure. The sealing structure is used for sealing a radial clearance between a first component and a second component, and comprises a sealing member and a dustproof member, wherein the sealing member is sealed in the radial clearance, the dustproof member is located on an axial outer side of the sealing member, a first end of the dustproof member is fixed on the first component, an opposite second end extends in a radial direction so as to cover the radial clearance, and the second end and the second component are spaced apart and partially overlap with each other in an axial direction. Since the dustproof member is not arranged in the radial clearance, the axial size of the radial clearance is reduced, and axial sizes of the first component and the second component are also accordingly reduced. The sealing structure is especially suitable for the inner wheel drive system, is helpful for reducing the axial size of the inner wheel drive system, and improves the applicability of the inner wheel drive system.
