[0023] The embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0024] The front fork steering assembly according to an embodiment of the present application is described below in conjunction with Figure 1 and Figure 2

[0025] The front fork steering assembly according to an embodiment of the present application includes a front fork assembly 1, a head tube 2, a first bowl group bearing 3, a limiting piece 4 and a corrugated gasket 5. The front fork assembly 1 includes a front fork body 11 and a front fork vertical pipe 12, the head tube 2 is sleeved on the front fork vertical pipe 12 and can rotate relative to the front fork vertical pipe 12, the first bowl group bearing 3 is sleeved on the front fork vertical pipe 12 and located on the upper side of the head tube 2, the limiting piece 4 is connected with the front fork vertical pipe 12 and located on the side of the first bowl group bearing 3 away from the head tube 2, and the corrugated gasket 5 is sleeved on the front fork vertical pipe 12, the corrugated gasket 5 is arranged on the lower side of the limiting piece 4 and used to eliminate the assembly gap between the limiting piece 4 and the front fork body 11 through axial elastic deformation.

[0026] The front fork steering assembly according to an embodiment of the present application, the front fork vertical pipe 12 of the front fork assembly 1 is connected with the limiting piece 4 after passing through the head tube 2, the first bowl group bearing 3 and the corrugated gasket 5, so as to complete the assembly of the front fork steering assembly. Among them, the corrugated gasket 5 is usually in a compressed state along its axial direction, which can effectively offset the assembly gap caused by wear or assembly error of the parts in the front fork steering assembly through elastic deformation, thereby effectively avoiding the loosening and shaking of the front fork steering assembly, and as long as the corrugated gasket 5 is still in the compressed state, it is basically unnecessary to maintain, thereby greatly prolonging the maintenance period of the front fork steering assembly and effectively reducing the maintenance cost.

[0027] In some embodiments, the corrugated gasket 5 is clamped between the first bowl group bearing 3 and the limiting piece 4.

[0028] ​That is, the corrugated gasket 5 is located on the upper side of the first bowl group bearing 3. This arrangement can eliminate the gap between the first bowl group bearing 3 and the head tube 2 without changing the structure of the joint between the first bowl group bearing 3 and the head tube 2, and the cost of modifying the front fork steering assembly is lower.

[0029] In some embodiments, the outer circumferential surface of the front fork vertical tube 12 is provided with external threads, and the limiting member 4 includes a nut that is threadedly connected with the external threads.

[0030] Thus, the assembly of the front fork steering assembly is convenient and reliable. By adjusting the size of the nut screwed into the front fork vertical tube 12, the axial compression amount of the corrugated gasket 5 can be adjusted. The adjustment of the elastic force of the corrugated gasket 5 is simple and convenient.

[0031] For example, the corrugated gasket 5 can be clamped between the nut and the first bowl group bearing 3.

[0032] In some embodiments, the inner circumferential surface of the front fork vertical tube 12 is provided with internal threads, and the limiting member 4 is in a sleeve structure and includes a threaded segment 41 and a limiting segment 42 arranged in sequence along the axial direction of the limiting member 4. The threaded segment 41 is threadedly connected with the internal threads, and a portion of the limiting segment 42 protrudes outward from the outer circumferential surface of the front fork vertical tube 12.

[0033] At this time, the corrugated gasket 5 can also be clamped between the limiting segment 42 and the first bowl group bearing 3 to ensure that the front fork steering assembly is not loose or shaken. The threaded segment 41 is threadedly connected with the internal threads, and the limiting segment 42 abuts against the upper end surface of the front fork vertical tube 12, which means that the front fork steering assembly is assembled. This effectively avoids the situation that the limiting member 4 compresses the corrugated gasket 5 too tightly, causing the first bowl group bearing 3 to be stuck, and also effectively avoids the situation that the limiting member 4 compresses the corrugated gasket 5 too little, failing to reliably eliminate the assembly gap.

[0034] For example, as shown in Figure 1 and Figure 2 the limiting member 4 is a hollow nut, and the cross-sectional outer contour of the limiting segment 42 is a regular polygon.

[0035] In some embodiments, the front fork steering assembly further includes an adapter tube 6. The adapter tube 6 is sleeved on the front fork vertical tube 12, the corrugated gasket 5 is clamped between the adapter tube 6 and the first bowl group bearing 3, and / or the corrugated gasket 5 is clamped between the adapter tube 6 and the limiting segment 42.

[0036] By providing the adapter tube 6, the front fork vertical tube 12 can be easily disassembled from the stand tube of the scooter, effectively improving the assembly efficiency of the scooter. At this time, whether the corrugated gasket 5 is clamped between the adapter tube 6 and the first bowl group bearing 3 or clamped between the adapter tube 6 and the limiting segment 42, the front fork steering assembly can effectively avoid loosening or shaking.

[0037] For example, as shown in Figure 1 and Figure 2As shown, the head tube 2, the first cup set bearing 3, the corrugated gasket 5, the adapter tube 6 and the limiting member 4 are arranged in sequence from bottom to top.

[0038] In some embodiments, the number of corrugated gaskets 5 is one and clamped between the adapter tube 6 and the first cup set bearing 3. The front fork steering assembly further comprises a flat gasket 7, which is sleeved on the front fork vertical tube 12 and arranged between the adapter tube 6 and the limiting section 42.

[0039] In this way, the front fork steering assembly is prevented from loosening and shaking, and the arrangement of the flat gasket 7 effectively prevents the limiting member 4 from being mis-rotated and loosened relative to the front fork vertical tube 12, thereby ensuring the assembly reliability of the front fork steering assembly.

[0040] For example, the lower side of the flat gasket 7 also abuts against the upper end surface of the front fork vertical tube 12, and the two side surfaces of the flat gasket 7 are provided with anti-skid patterns to further ensure the relative fixation of the limiting member 4 and the adapter tube 6 in the circumferential direction of the front fork vertical tube 12.

[0041] Alternatively, the number of corrugated gaskets 5 can also be two, one of which is clamped between the adapter tube 6 and the limiting section 42.

[0042] In some embodiments, as shown in Figure 1 and Figure 2 The front fork steering assembly further comprises a dust cover 9, which is sleeved on the front fork vertical tube 12 and located between the first cup set bearing 3 and the corrugated gasket 5, and covers part of the first cup set bearing 3.

[0043] The dust cover 9 separates the rollers in the first cup set bearing 3 from the outside, thereby effectively preventing dust from entering the first cup set bearing 3 and affecting its service life. At the same time, the dust cover 9 replaces the abutment between the first cup set bearing 3 and the corrugated gasket 5, and the dust cover 9 is more convenient for axially compressing the corrugated gasket 5 to cause axial compression deformation of the corrugated gasket 5, and the axial anti-loosening effect of the front fork steering assembly is better.

[0044] In some embodiments, the front fork steering assembly further comprises a limiting sleeve 8, which is sleeved on the front fork vertical tube 12 and has an open loop structure, one part of the limiting sleeve 8 is clamped between the dust cover 9 and the first cup set bearing 3, and the other part of the limiting sleeve 8 is clamped between the first cup set bearing 3 and the front fork vertical tube 12.

[0045] By inserting one part of the limiting sleeve 8 into the gap between the first cup set bearing 3 and the front fork vertical tube 12, the radial shaking of the first cup set bearing 3 relative to the front fork vertical tube 12 is effectively avoided, thereby improving the user's riding experience and safety.

[0046] For example, as shown in Figure 1 and Figure 2As shown, the thickness of the limiting sleeve 8 gradually increases from bottom to top, so as to facilitate the downward insertion of the limiting sleeve 8 into the gap between the first cup set bearing 3 and the front fork vertical pipe 12.

[0047] Need to explain, the front fork steering assembly further comprises a second cup set bearing, the second cup set bearing is sleeved on the front fork vertical pipe 12 and is arranged between the front fork body 11 and the head tube 2. The head tube 2 is arranged between the first cup set bearing 3 and the second cup set bearing, so that the rotation of the front fork assembly 1 relative to the head tube 2 is more labor-saving, stable and reliable.
