Technical Field

[0001] This invention relates to a hub assembly and a hub bearing adjustment tool system. Background Technology

[0002] The human-powered vehicle includes a hub assembly. The hub assembly includes a hub shaft, a hub housing rotatably supported by the hub shaft, and a bearing. The bearing is located near the axial end of the hub housing. When the bearing is at least partially located outside the axial end of the hub housing, this narrows the space around the axial end of the hub housing. Preferably, a larger space is ensured around the axial end of the hub housing to accommodate another part of the human-powered vehicle. Summary of the Invention

[0003] According to a first aspect of the invention, a hub assembly includes a hub shaft, a hub housing, and a first bearing. The hub shaft extends along a rotation axis defining an axial direction. The hub housing is rotatably supported about the hub shaft and includes a first housing end portion, a second housing end portion, and a rotor attachment portion to which a brake rotor is to be attached. The hub housing extends axially between the first housing end portion and the second housing end portion. The rotor attachment portion is disposed at the first housing end portion. The first bearing is configured to rotatably support the first housing end portion relative to the hub shaft about a rotation axis. The first bearing includes a first inner race, a first outer race, and at least one first rolling member. The first inner race is coupled to the hub shaft. The first outer race is coupled to the hub housing. At least one first rolling member is disposed between the first inner race and the first outer race. The first housing end portion includes a first housing axial end surface facing the axial direction. The first inner race includes a first inner race axial end surface and a first additional inner race axial end surface. The first inner race extends axially between the first inner race axial end surface and the first additional inner race axial end surface. The axial end surface of the first additional inner race is configured to be closer to the second housing end portion in the axial direction than the axial end surface of the first inner race. The axial end surface of the first inner race is configured to be closer to the second housing end portion in the axial direction than the axial end surface of the first housing end portion. The hub shaft includes a first external thread portion. The first inner race includes a first internal thread portion configured to engage with the first external thread portion. The axial end surface of the first inner race is configured to be closer to the second housing end portion in the axial direction than the axial end surface of the first housing end portion when the first internal thread portion engages with the first external thread portion.

[0004] Using the hub assembly according to the first aspect, the positional relationship between the axial end surface of the first inner race and the axial end surface of the first housing ensures the space surrounding the end portion of the first housing. Therefore, another component can be arranged using the space surrounding the axial end of the first housing.

[0005] According to a second aspect of the invention, the hub assembly according to the first aspect is configured such that the rotor attachment portion has an annular shape. A first inner race is at least partially disposed radially inward on the rotor attachment portion. Using the hub assembly according to the second aspect, the first inner race can be arranged within the radially inner space of the rotor attachment portion. Therefore, the space surrounding the axial end of the first housing can be effectively utilized to arrange another component.

Figure 3 The axial end surface 34A of the first inner race is completely configured to be further away from the second housing end portion 14B in the axial direction D1 than at least one threaded hole 16A (see, for example, [reference needed]). Figure 3 Alternatively, the first inner race 34 may be configured to be closer to the second housing end portion 14B in the axial direction D1 than at least one threaded hole 16A (e.g., see...). Figure 3 The axial end surface 34A of the first inner race can be at least partially configured to be closer to the second housing end portion 14B in the axial direction D1 than at least one threaded hole 16A (e.g., see...). Figure 3 The first inner race 34 may be configured at least partially to be further away from the second housing end portion 14B in the axial direction D1 than at least one threaded hole 16A (see, for example, see...). Figure 3 ).

[0051] The first inner race 34 includes a first curved surface 34D. The first curved surface 34D is contactable with at least one first rolling member 38. The first curved surface 34D extends from the axial end surface 34B of the first additional inner race. The first curved surface 34D is at least partially disposed radially outward of the axial end surface 34B of the first additional inner race.

[0052] The rotor attachment portion 16 includes a stop portion 16C that projects radially inward from the inner circumferential surface 16B. The stop portion 16C contacts the first outer race 36 to position the first outer race 36 in the axial direction D1. At least one first rolling member 38 and the first outer race 36 are held between the first inner race 34 and the stop portion 16C.

[0053] like Figure 4 As shown, the hub assembly 10 also includes a locking member 42. The locking member 42 is configured to restrict the first inner race 34 from moving away from the second housing end portion 14B relative to the hub shaft 12 in the axial direction D1 (see, for example, see...). Figure 3The locking member 42 is configured to be coupled to the hub shaft 12 to restrict the first inner race 34 from moving away from the second housing end portion 14B in the axial direction D1 relative to the hub shaft 12 (see, for example, see...). Figure 3 The locking member 42 is contactable with the axial end surface 34A of the first inner race 34 to restrict the first inner race 34 from moving away from the second housing end portion 14B relative to the hub shaft 12 in the axial direction D1 (see, for example, see...). Figure 3 (Movement). Locking member 42 has a ring shape.

[0054] The locking member 42 is configured to hold the first inner race 34, at least one first rolling member 38, and the first outer race 36 between the locking member 42 and the stop portion 16C in the axial direction D1. The locking member 42 is configured to apply an axial force to the first inner race 34 in the axial direction D1 to hold the first inner race 34, at least one first rolling member 38, and the first outer race 36 between the locking member 42 and the stop portion 16C in the axial direction D1.

[0055] The locking member 42 includes a locking member axial end surface 42A and an additional locking member axial end surface 42B, and extends along the axial direction D1 between the locking member axial end surface 42A and the additional locking member axial end surface 42B. The locking member 42 is at least partially configured to be closer to the second housing end portion 14B in the axial direction D1 than the locking member axial end surface 42A (see example). Figure 3 The axial end surface 42B of the additional locking member is at least partially configured to be closer to the second housing end portion 14B in the axial direction D1 than the axial end surface 42A of the locking member (see, for example...). Figure 3 The axial end surface 42A of the locking member is at least partially configured to be further away from the second housing end portion 14B in the axial direction D1 than the first housing end surface 14C of the first housing end portion 14A (see, for example...). Figure 3 ).

[0056] In this embodiment, the locking member 42 is partially configured to be closer to the second housing end portion 14B in the axial direction D1 than the axial end surface 42A of the locking member (see, for example...). Figure 3 The axial end surface 42B of the additional locking member is configured to be closer to the second housing end portion 14B in the axial direction D1 than the axial end surface 42A of the locking member (see, for example...). Figure 3 The axial end surface 42A of the locking member is completely positioned further away from the second housing end portion 14B in the axial direction D1 than the first housing end surface 14C of the first housing end portion 14A (see example). Figure 3 ).

[0057] Alternatively, the locking member 42 may be configured to be closer to the second housing end portion 14B in the axial direction D1 than the axial end surface 42A of the locking member (see, for example...). Figure 3 The axial end surface 42B of the additional locking member may be partially positioned closer to the second housing end portion 14B in the axial direction D1 than the axial end surface 42A of the locking member (see, for example...). Figure 3 The axial end surface 42A of the locking member may be partially configured to be further away from the second housing end portion 14B in the axial direction D1 than the first housing end surface 14C of the first housing end portion 14A (see example). Figure 3 The axial end surface 42A of the locking member may be at least partially positioned closer to the second housing end portion 14B in the axial direction D1 than the first housing end surface 14C of the first housing end portion 14A (see example). Figure 3 ).

[0058] The locking member 42 includes an internal threaded portion 42C configured to engage with the first external threaded portion 12C. In this embodiment, the locking member 42, when the internal threaded portion 42C is engaged with the first external threaded portion 12C, is configured to be closer to the second housing end portion 14B in the axial direction D1 than the first housing axial end surface 14C of the first housing end portion 14A. Alternatively, the locking member 42, when the internal threaded portion 42C is engaged with the first external threaded portion 12C, may be partially configured to be closer to the second housing end portion 14B in the axial direction D1 than the first housing axial end surface 14C of the first housing end portion 14A.

[0059] The first inner race 34 has a first inner radius R1 radially defined from the rotation axis A1. For example, the first inner radius R1 is radially defined from the rotation axis A1 to the first internal thread portion 34C. The first inner race 34 has a first outer radius R2 radially defined from the rotation axis A1. The locking member 42 has an outer radius R3 radially defined from the rotation axis A1. In this embodiment, the outer radius R3 of the locking member 42 is greater than the first inner radius R1. The outer radius R3 of the locking member 42 is less than the first outer radius R2. Alternatively, the outer radius R3 of the locking member 42 may be greater than or equal to the first outer radius R2.

[0060] The hub assembly 10 includes a sealing member 44 disposed in the internal space 16S. The sealing member 44 has an annular shape. The sealing member 44 is disposed between the first inner bearing ring 34 and the inner peripheral surface 16B of the rotor attachment portion 16 to protect the first bearing 30 from foreign matter.

[0061] The first inner race 34 is configured to rotate using a first tool. The locking member 42 is configured to rotate using a second tool. An example of the first tool includes a wrench. An example of the second tool includes a wrench. Rotation of the first inner race 34 moves the first inner race 34 toward the stop 16C, holding at least one first rolling member 38 and the first outer race 36 between the first inner race 34 and the stop 16C in the axial direction D1. Rotation of the locking member 42 moves the locking member 42 toward the first inner race 34, thereby restricting loosening of the first inner race 34.

[0062] However, as Figure 4 As shown, the first inner race 34 is completely disposed within the rotor attachment portion 16. The locking member 42 is at least partially disposed within the rotor attachment portion 16. This arrangement may make it more difficult to rotate the first inner race and / or the locking member using the first tool and / or the second tool.

Figure 8 At least one first engagement surface 58A is contactable with at least one inner race engagement surface 72A of the first inner race tool engagement portion 34E (see, for example, see...). Figure 8 In this embodiment, the first engagement structure 58 includes at least two first engagement surfaces 58A. The first engagement surfaces 58A include flat surfaces. The total number of first engagement surfaces 58A is four. Alternatively, the total number of first engagement surfaces 58A may be less than or greater than four.

[0079] like Figure 10 As shown, the first inner race 34 is configured to rotate relative to the hub shaft 12 about a rotation axis A1 using a first tool member 52. The first internal thread portion 34C and the first external thread portion 12C respond to the rotation of the first inner race 34 about the rotation axis A1, causing the first inner race 34 to move relative to the hub shaft 12 in the axial direction D1. Therefore, the axial position of the first inner race 34 is changed using the first tool member 52.

[0080] The locking member 42 is configured to rotate relative to the hub shaft 12 about the rotation axis A1 using the second tool member 54.
