Description

TECHNICAL FIELD

[0001] The utility model belongs to bicycle technical field, concretely relates to a flywheel and flywheel tower base module. BACKGROUND

[0002] The flywheel is an important component in the bicycle transmission system. The flywheel is installed on the rear wheel shaft of the bicycle through the tower base, so that the flywheel can work cooperatively with the rear wheel to realize the speed change function of the bicycle. The tower base provides a stable installation foundation for the flywheel to ensure that the flywheel maintains a stable position during rotation, so that the chain can accurately mesh with the teeth of the flywheel, thereby realizing smooth speed change and power transmission. During riding, the power generated by pedaling is transmitted to the flywheel through the chain, and then transmitted to the tower base by the flywheel, and finally transmitted to the rear wheel by the tower base to drive the bicycle forward. By cooperating with flywheels of different gears and operating the speed change system, the chain is switched between flywheels of different gear numbers, thereby changing the transmission ratio of the bicycle to achieve different riding speeds to adapt to different road conditions and riding needs.

[0149] The first gasket 131 can be in an integrated structure with the second flywheel piece 121 and the small-diameter flywheel piece 111. Alternatively, the first gasket 131 can be connected to the second flywheel piece 121 and the small-diameter flywheel piece 111 in an integrated structure through welding or other connection methods.

[0150] The first gasket 131 is arranged along the axial direction of the outer wall of the tower base body 210, and therefore, the first gasket 131 is connected to the middle part of the second flywheel piece 121.

[0151] Through the clamping of the first gasket 131 and the tower base body 210, the clamping of the first gasket 131, the small-diameter flywheel piece 111, the second flywheel piece 121 and the tower base body 210 as a whole is achieved, so that the first gasket 131, the small-diameter flywheel piece 111, the second flywheel piece 121 as a whole rotate with the tower base body 210.

[0152] In order to achieve the clamping of the tower base body 210 and the flywheel body module 120, the tower base body 210 comprises a tower base cylinder 215 and an outer clamping part 213 formed on the outer wall of the tower base cylinder 215.

[0153] As shown in Figure 2 , the outer clamping part 213 comprises a first outer clamping part 2131 and a second outer clamping part 2132.

[0154] The first outer clamping part 2131 is formed on the main body outer wall of the tower base cylinder 215, and the second outer clamping part 2132 is formed at the end outer wall of the tower base cylinder 215.

[0155] As shown in Figure 11 , the flywheel body module 120 further comprises a first inner clamping part 122, and the first inner clamping part 122 is arranged along the inner wall of the plurality of flywheel pieces.

[0156] AsFigure 12 As shown, the flywheel body module 120 further comprises a second inner clamping portion 123, which is arranged along the inner wall of the plurality of pads.

[0157] The first inner clamping portion 122, the second inner clamping portion 123 and the first outer clamping portion 2131 are clamped.

[0158] A third inner clamping portion 1311 is formed on the inner wall of the first pad 131. The third inner clamping portion 1311 is clamped with the second outer clamping portion 2132.

[0159] As shown in Figure 13 , Figure 14 Since the small-diameter flywheel piece 111 and the second flywheel piece 121 are both clamped with the second outer clamping portion 2132 through the first pad 131, the third inner clamping portion 1311 is formed on the inner wall of the first pad 131, and in order to ensure the stability of the clamping, the third inner clamping portion 1311 needs to have a certain length.

[0160] The flywheel piece adjacent to the second flywheel piece 121 is defined as a third flywheel piece 124.

[0161] The pad adjacent to the first pad 131 is defined as a second pad 132.

[0162] The second pad 132 is connected with the third flywheel piece 124. The second pad 132 is connected to the side of the third flywheel piece 124 away from the second flywheel piece 121.

[0163] In order to ensure that the third inner clamping portion 1311 has sufficient length, an annular recess 1221 is formed on the third flywheel piece 124 close to the side of the second flywheel piece 121. The first pad 131 can extend the length of the third inner clamping portion 1311 by extending into the annular recess 1221.

[0164] In order to be able to form the annular recess 1221 in the third flywheel piece 124, the third flywheel piece 124 and the second pad 132 are of an integral structure.

[0165] Since the first pad 131 can extend into the annular recess 1221, the thickness of the first pad 131 is limited, in order to ensure that the first pad 131 has sufficient thickness at the position where the third inner clamping portion 1311 is formed, the height of the second outer clamping portion 2132 needs to be lower than the height of the first outer clamping portion 2131, so that the height of the third inner clamping portion 1311 clamped with the second outer clamping portion 2132 is less than the height of the first inner clamping portion 122 and the second inner clamping portion 123.

[0166] In some embodiments of the present application, the remaining pads and flywheel pieces can adopt an integrated structure, or can be connected by different connection methods, or can adopt a split form of pads and flywheel pieces.

[0167] The inner diameter contraction flywheel module 110 includes 10T flywheel pieces, as shown in the figure. Figure 15 As shown, by means of the annular groove 230 formed by the tower base body 210 and the tower base end cover 220, the outer diameter of the annular groove 230 is smaller than the inner diameter of the 10T flywheel piece, so that the use of the tower base 200 is extended to be compatible with the minimum 10T flywheel piece.

[0168] In some embodiments of the present application, the tower base 200 can also be used to install a flywheel piece with a minimum gear of 11T, and the compatibility of the above-mentioned tower base 200 needs to be ensured, and thus the tower base 200 also includes an extension part 240, and a plurality of positioning pins 241 are arranged on the extension part 240 in a spaced manner. A plurality of positioning holes 214 are arranged on the second end of the tower base body 210 in a spaced manner. The plurality of positioning pins 241 and the plurality of positioning holes 214 are inserted to connect the extension part 240 to the tower base body 210, and the extension part 240 is accommodated in the annular groove 230.

[0169] Specifically, the extension part 240 can adopt a circular ring structure. The extension part 240 is coaxially arranged with the tower base body 210.

[0170] The second end of the flywheel 100 is used to be sleeved outside the extension part 240. The tower base body 210 and the extension part 240 are both sleeved outside the wheel shaft 300.

[0171] In order to facilitate the flywheel 100 to be sleeved outside the tower base 200, the extension part 240 is not affected, and the outer wall of the extension part 240 is arranged in alignment with the outer wall of the tower base cylinder 215.

[0172] In addition, the outer diameter of the second mounting part is smaller than the inner diameter of the extension part 240, so that the tower base end cover 220 can pass through the extension part 240 and be connected with the first mounting part 212.

[0173] In the description of the above embodiments, specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

[0174] As long as possible, various aspects and features described and shown in the specification can be applied alone, and these individual aspects can be the subject of a divisional application.

[0175] The above merely is the specific implementation manner of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can easily think of the changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application, therefore, the protection scope of the present application should be subject to the protection scope of the claims.
