Description

Technical Field

[0001] This disclosure relates generally to bicycle components, and more specifically to brake mounts for bicycles. Background Technology

[0002] Bicycles and other human-powered vehicles typically include disc brakes. A disc brake consists of a brake rotor and a brake caliper. The brake rotor is usually mounted to the hub of the bicycle wheel, and the brake caliper is mounted to a fixed part of the bicycle (such as the frame). When the brake caliper is actuated, it moves one or more brake pads to engage with the brake rotor, which slows the rotor down, thus reducing the bicycle's speed. Summary of the Invention

[0026] In this document, descriptors such as "first," "second," and "third" are used when identifying multiple elements or components that can be individually mentioned. Unless otherwise specified or understood based on the context of their use, such descriptors are not intended to imply any temporal priority or ordering, but merely serve as labels for individually mentioning multiple elements or components to facilitate understanding of the disclosed embodiments. In some embodiments, the descriptor "first" may be used to refer to an element in a detailed description, while the same element may be mentioned in the claims using different descriptors (such as "second" or "third"). In such cases, it should be understood that the use of such descriptors is merely for the convenience of mentioning multiple elements or components. Detailed Implementation

[0027] Brakes on modern bicycles (including e-bikes) have evolved to utilize technology from automotive braking systems, such as disc brakes. Compared to the traditional rim and cable brakes used in the past, disc brakes offer greater stopping power and deceleration control. The front and / or rear brakes on a bicycle can be implemented as disc brakes.

[0028] Disc brakes consist of a brake rotor and a brake caliper. The brake rotor is typically attached to and rotates with the hub on the bicycle wheel. The brake caliper is usually mounted near the brake rotor to a fixed part of the bicycle (such as the frame). When the brake caliper is actuated, it moves two brake pads into contact with the outer surface of the brake rotor. The friction between the brake pads and the brake rotor causes the brake rotor to decelerate, thereby reducing the speed of the wheel and thus the speed of the bicycle.

[0029] A small clearance between the brake pads and the brake rotor is important for achieving high braking force while maintaining proper lever ergonomics. The relevant physical values ​​for rider ergonomics are lever travel and actuation force. Furthermore, when not braking, contact between the brake rotor and brake pads is undesirable, as this generates wasted rolling friction, resulting in slowing of the bicycle and unnecessary wear on both the brake rotor and brake pads. This contact can also lead to unwanted noise (e.g., brake squeaking).

[0030] Therefore, a major challenge in proper brake setup is achieving precise parallel alignment between the brake pads and the brake rotor. This parallel alignment depends on the axial and radial position of the brake caliper relative to the brake rotor. Current disc brake assemblies require a laborious adjustment process to ensure the brake rotor is centered between the brake pads to avoid non-braking contact. Typically, the brake caliper and / or brake rotor require multiple shims or spacers to aid in this centering adjustment. With current brake designs, this alignment must be manually adjusted during brake caliper assembly. This process requires manual dexterity and often results in improper brake setup and rider dissatisfaction.

[0031] The rear triangle of a bicycle frame includes a through-hole on the left frame section and a threaded hole on the right frame section. The rear hub assembly includes a hub that is mounted between the two frame sections of the rear triangle using a through-axle (e.g., a bolt). The left and right frame sections include a left chainstay and a left rear stay, and a right chainstay and a right rear stay. To accommodate the wheel, the chainstays and rear stays extend a relatively long distance from their connection to the main frame (e.g., the length of a standard chainstay is approximately 430 to 460 mm). This geometric boundary condition affects the alignment tolerances of the holes in the frame sections. In particular, the through-hole is typically larger than the size required to fix the axle, allowing the axle to fit loosely within the through-hole. This allows the rear hub assembly to move relative to the frame and compensate for the tolerances of the holes in the frame sections. When the brake caliper is mounted to the frame, the mounting accuracy relative to the brake rotor is directly affected by this compensation. While some known systems utilize brake mounts to connect the brake calipers to the frame, these mounts are fixed or rigidly attached to the frame, thus providing a strong reference point to the frame. Consequently, the brake rotor (reference to the rear wheel hub) and the brake caliper (reference to the frame) may be slightly misaligned. As mentioned above, this complicates the process of aligning the brake caliper with the brake rotor to ensure that the brake pads are parallel and equidistant from the brake rotor.

[0032] As used herein, the terms "axial," "axially," and other variations refer to a direction that coincides with or is parallel to the axis of rotation, which may be defined by the brake rotor and / or the hub. As used herein, the terms "radial," "radially," and other variations refer to a direction extending orthogonally from the axis of rotation, which may include a radially inward direction toward or away from the axis of rotation. As used herein, the terms "circumferential," "circumferentially," and other variations refer to a direction extending concentrically about the axis of rotation. As used herein, the term "inner side" refers to the central plane of the wheel or other rotatable object in the axial direction. As used herein, the term "outer side" refers to the central plane of the wheel or other rotatable object in the axial direction.

[0033] This document discloses an exemplary brake mount and a hub assembly having the exemplary brake mount, which at least addresses the aforementioned disadvantages. The exemplary brake mount can be used to attach a brake caliper to a bicycle. The exemplary brake mount disclosed herein can be considered a universal brake mount or adapter. The exemplary brake mount can be used to mount various brake calipers to a bicycle. The exemplary brake mount disclosed herein establishes a stronger or absolute axial and radial reference to the hub assembly rather than the frame. Therefore, even if the frame's dimensional tolerances allow for misalignment between the rear hub assembly and the frame, the brake caliper and brake rotor remain axially and radially aligned. This reduces or eliminates the time required to precisely position the brake caliper relative to the brake rotor during initial setup and over time, which is required by conventional brakes. The exemplary brake mount disclosed herein also reduces or eliminates unbalanced braking forces and unwanted brake friction, thereby improving braking performance and extending the lifespan of braking components.

[0034] The exemplary brake mount disclosed herein includes a bracket for attaching a brake caliper to a bicycle. In some embodiments, the brake caliper is attached to the bracket via one or more threaded fasteners (e.g., bolts). The bracket is to be disposed inside the bicycle frame between the hub of the rear wheel assembly and the frame. The bracket includes a first opening for receiving the axle of the rear wheel assembly. Specifically, when the bracket is mounted on the bicycle, the axle extends through the frame, through the bracket, and through the hub. The bracket also includes a second opening. A post extends through the second opening and into a frame component (e.g., the left rear seat fork). During braking, forces are transmitted via the bracket to the post, and thus to the frame.

[0035] In some embodiments disclosed herein, the brake mount includes a sleeve that is coupled to and extends from one side of the bracket. The sleeve is coaxial with a first opening. When the brake mount is mounted on a bicycle, the sleeve extends into an axle opening in the frame, and the axle extends through the sleeve. In some embodiments, the sleeve extends fully through the axle opening such that the distal end of the sleeve is positioned outside the frame. In other embodiments, the sleeve extends only partially into the axle opening. In some embodiments, the distal end of the sleeve is threaded, and the brake mount includes a nut that can be screwed onto the distal end of the sleeve after the sleeve is inserted into or through the axle opening in the frame. In some embodiments, the sleeve and the bracket are integral. The sleeve establishes a strong and precise reference between the hub assembly and the bracket. In particular, the sleeve is relatively long. This allows for a wider support width between the sleeve and the axle. In some embodiments, the sleeve and the axle form a transition fit (sometimes referred to as a slip fit) or an interference fit (sometimes referred to as a friction fit or press fit). The wider support width and fit create a strong radial reference between the sleeve and the shaft, and consequently, a strong radial reference between the bracket and the shaft. Furthermore, when the shaft is tightened, the sleeve and bracket are axially clamped between the shaft head and the hub. This establishes a strong axial reference between the bracket and the hub assembly. Therefore, the brake caliper maintains a stronger axial and radial reference to the rear hub assembly, and thus, a stronger axial and radial reference to the brake rotor.

[0036] In some embodiments, the second opening is implemented as a collar clamp. For example, the brake mount may include a clamping bolt that can be screwed into the bracket to clamp the bracket to the post at the second opening. In some embodiments, the clamping bolt is tightened after the bracket is mounted to the wheel hub assembly. This allows the bracket to maintain a weaker axial reference to the frame so that the bracket can maintain a stronger axial reference to the rear wheel hub assembly. Additionally, in some embodiments, the second opening extends radially. This allows the brake mount to compensate for distance tolerances between the centers of the first and second openings and between the equidistant positions of the frame through-hole center and the post center. In some embodiments, optimal alignment is achieved by means of the disclosed reference and tolerance design and assembly sequence. As an exemplary assembly process, first, the brake mount is assembled to the frame without tightening the sleeve nut. Second, the wheel hub is assembled to the axle and maximum axle torque is applied. In this configuration, the brake mount and wheel hub are precisely positioned, but the loose fit between the brake mount and the frame is misaligned in a way that compensates for system tolerances. Third, the sleeve nut is tightened, thus fixing the misalignment. The bracket can then be secured to the post at the second opening, thereby fixing the axial alignment in the current position. Alternatively, in other embodiments, there may be no means or device for axial fixation on the post, and the axial position will be maintained by means of a brake support structure. This is advantageous compared to known brake support systems, because axial fixation of the brake support to the frame causes the brake support to bend towards the frame, so known brake supports offer almost no reference to the wheel hub.

[0037] The embodiments disclosed herein are also advantageous for vibration management, an important consideration in braking system design. Resonant frequencies can cause hum and other performance and safety issues. The structural and elastic characteristics of the main load-bearing components have a direct impact on such vibrations. Known brake designs include frame or adapter elements within the load path that are not optimized for the braking system environment. The exemplary brake mounts disclosed herein are configured to guide the load path through a strongly referenced and optimized structure. The axial distance from the brake rotor to the torque support region at the second opening constitutes a lever for torsional loads. In some embodiments, this distance is significantly shorter compared to known designs, thus reducing deformation within the brake mount. The torsional load is at least partially absorbed by the frame and therefore does not interfere with the direct load path of the brake mount. In particular, this exemplary brake mount significantly improves torsional loads on the main load elements compared to known designs. Therefore, the exemplary brake mounts disclosed herein allow for frame-independent braking system optimization, thereby improving performance, enhancing safety, and reducing weight and cost (including savings in frame development, testing, and manufacturing costs).

[0038] Now turn to the diagram. Figure 1An embodiment of a human-powered vehicle is illustrated, on which the exemplary brake mounts and related components disclosed herein may be implemented. In this embodiment, the vehicle is a bicycle 100, such as a mountain bike. In the illustrated embodiment, the bicycle 100 includes a frame 102 and a front wheel 104 and a rear wheel 106, which are rotatably coupled to the frame 102. In the illustrated embodiment, the front wheel 104 is coupled to the front end of the frame 102 via a front fork 108. In some embodiments, the front fork 108 includes one or more shock-absorbing components (e.g., shock absorbers) to absorb shocks or vibrations. The front wheel 104 is rotatably coupled to the front fork 108 via a front hub assembly 110. The rear wheel 106 is coupled to the frame 102 to support the rear end of the frame 102. The rear wheel 106 is rotatably coupled to the frame 102 via a rear hub assembly 112. In some embodiments, one or more shock-absorbing components may be coupled between the rear wheel 106 and the frame 102 to absorb shocks or vibrations. The forward and / or forward-facing riding direction or orientation of bicycle 100 is determined by... Figure 1 The direction of arrow A is indicated in the diagram. Thus, the forward movement direction of bicycle 100 is indicated by the direction of arrow A. Bicycle 100 is shown as being ridden on riding surface 114. Riding surface 114 can be any riding surface, such as the ground (e.g., dirt road, sidewalk, street, etc.), man-made structures above the ground (e.g., wooden ramps), and / or any other surface.

[0039] In the illustrated embodiment, bicycle 100 includes a seat 116 connected to frame 102 via seatpost 118 (e.g., near the rear end of frame 102 relative to forward direction A). Bicycle 100 also includes handlebars 120 connected to frame 102 and fork 108 (e.g., near the front end of frame 102 relative to forward direction A) for maneuvering bicycle 100. In the illustrated embodiment, bicycle 100 has a drivetrain 122 including crank assembly 124. Crank assembly 124 is operatively connected to sprocket assembly 128 via chain 126. Sprocket assembly 128 is mounted to rear wheel hub assembly 112. Crank assembly 124 includes at least one (typically two) crank arms 130 and pedals 132, and at least one front sprocket or chainring 134. Exemplary bicycle 100 may include a rear derailleur (e.g., derailleur) and / or a front derailleur to move chain 126 through different sprockets.

[0040] Figure 1An exemplary bicycle 100 includes an exemplary braking system 136. The exemplary braking system 136 can be used to reduce the speed of the bicycle 100. The exemplary braking system 136 includes: a front brake 138 for slowing the rotation of a front wheel 104; and a rear brake 140 for slowing the rotation of a rear wheel 106. In this embodiment, the front brake 138 and the rear brake 140 are implemented as hydraulic disc brakes. The front brake 138 includes a front brake rotor 142 (sometimes referred to as a brake disc) and a front brake caliper 144. The front brake rotor 142 is coupled to and rotates with the front wheel 104 on a front hub assembly 110. In the illustrated embodiment, the front brake caliper 144 is coupled to the front fork 108 near the front brake rotor 142. When the front brake caliper 144 is actuated, the front brake caliper 144 moves one or more brake pads to engage with the front brake rotor 142 to slow the front brake rotor 142, thereby slowing the rotation of the front wheel 104. In the illustrated embodiment, the braking system 136 includes a front brake actuator 146 (e.g., a lever) for actuating the front brake caliper 144. The front brake actuator 146 is coupled to the handlebars 120. The front brake actuator 146 is fluidly coupled to the front brake caliper 144 via a first fluid line 148. In this embodiment, the front brake actuator 146 is actuated by moving it toward a grip on the handlebars 120. This actuation causes brake fluid to be pushed onto the front brake caliper 144 to provide braking pressure on the front brake rotor 142. Conversely, the front brake actuator 146 is de-actuated by releasing or otherwise removing it from the grip, which releases or reduces the braking pressure on the front brake caliper 144.

[0041] Similarly, the rear brake 140 includes a rear brake rotor 150 and a rear brake caliper 152. The rear brake rotor 150 is coupled to and rotates with the rear wheel 106 via a rear hub assembly 112. When the rear brake caliper 152 is actuated, it moves one or more brake pads to engage with the rear brake rotor 150, thereby slowing the rear brake rotor 150 and thus reducing the rotational speed of the rear wheel 106. Similar to the front brake actuator 146, the braking system 136 includes a rear brake actuator 154 coupled to the handlebars 120 and used to actuate the rear brake caliper 152. The rear brake actuator 154 is fluidly coupled to the rear brake caliper 152 via a second fluid line 156. The rear brake actuator 154 and the rear brake caliper 152 operate similarly to the front brake actuator 146 and the front brake caliper 144.

[0042] While in this embodiment the front brake 138 and rear brake 140 are hydraulically actuated, in other embodiments the front brake 138 and / or rear brake 140 may be cable-actuated. For example, the rear brake actuator 154 may be connected to the rear brake caliper 152 via a cable. When the rear brake actuator 154 moves toward the handlebars 120, the cable is pulled to actuate the rear brake caliper 152. In the illustrations, the front brake rotor 142 and rear brake rotor 150 are arranged to the left of the front wheel 104 and rear wheel 106 (when facing direction A). In other embodiments, the front brake rotor 142 and / or rear brake rotor 150 may be arranged to the right of the front wheel 104 and rear wheel 106, respectively.

[0043] Although Figure 1 The exemplary bicycle 100 depicted herein is a type of mountain bike, but the exemplary brake mount and related components disclosed herein can be implemented on other types of bicycles. For example, the disclosed brake mount and related components can be used on road bicycles and bicycles with mechanical (e.g., cable, hydraulic, pneumatic, etc.) and non-mechanical (e.g., wired, wireless) drive systems. The disclosed brake mount and related components can also be implemented on other types of two-wheeled, three-wheeled, and four-wheeled human-powered vehicles. Furthermore, the exemplary brake mount and related components can be used on other types of vehicles, such as motor vehicles (e.g., motorcycles, cars, trucks, etc.). The exemplary brake mount and related components disclosed herein can be used under any road or towing conditions (e.g., hot, cold, wet, muddy, snowy, etc.).

[0044] Figure 2 and Figure 3 It is a bicycle 100 ( Figure 1 A perspective view of the rear portion of the frame 102 of a vehicle, showing an exemplary rear wheel hub assembly 112, an exemplary rear brake 140, and an exemplary brake support 200 for positioning the rear brake caliper 152 relative to the rear brake rotor 150. The exemplary brake support 200 may also be referred to as a brake support assembly, a brake adapter, or a brake adapter assembly. For clarity, the rear wheel 106 ( Figure 1 The spokes and tires have been removed.

[0045] In the illustrated embodiment, bicycle 100 ( Figure 1 The frame 102 has a left frame portion 202 and a right frame portion 204. The left frame portion 202 has a left chainstay 206 and a left rear seatstay 208, and the right frame portion 204 has a right chainstay 210 and a right rear seatstay 212. The left frame portion 202 and the right frame portion 204 may also be referred to as a frame triangle. The rear wheel hub assembly 112 is arranged between the left frame portion 202 and the right frame portion 204.

[0046] In the illustrated embodiment, the rear wheel hub assembly 112 includes a hub 214 and an axle 216 about which the hub 214 rotates. The rear wheel 106 ( Figure 2 and Figure 3 Not shown in the image, but... Figure 1 (As shown in the diagram) is connected to the hub 214 via a spoke-attachment flange. The hub 214 is arranged between the left frame portion 202 and the right frame portion 204. The axle 216 extends through the left frame portion 202 and the right frame portion 204 (e.g., at the intersection of the left chainstay 206 and the left rear seat fork 208, and the intersection of the right chainstay 210 and the right rear seat fork 212) and extends through the hub 214. The rear brake rotor 150 is connected to the hub 214 (e.g., via one or more threaded fasteners) and to the rear wheel 106 (… Figure 1 Together, they rotate about axis 216. Thus, axis 216 defines an axis of rotation 218 about which the hub 214 and rear brake rotor 150 rotate. The rear brake rotor 150 can be considered as part of the rear hub assembly 112. The rear brake caliper 152 can be actuated (e.g., via hydraulic pressure or cable) to move the brake pads so that the rear brake rotor 150 engages, thereby slowing the rear wheel 106 to decelerate the bicycle 100.

[0047] In the illustrated embodiment, the exemplary brake mount 200 includes a bracket 220. As disclosed in further detail herein, a rear brake caliper 152 is coupled to the bracket 220, and the bracket 220 is coupled to the bicycle 100 at one or more locations. Thus, the bracket 220 engages the rear brake caliper 152 to the bicycle 100. The bracket 220 precisely positions the rear brake caliper 152 relative to the rear brake rotor 150 so that the brake pads are axially and radially aligned with the rear brake rotor 150. In some embodiments, the brake mount 200 is a universal brake mount that can be used to engage different types (e.g., different brands, shapes, etc.) of brake calipers to the bicycle 100.

[0048] Figure 4 From and Figure 2 Exploded views of the exemplary rear wheel hub assembly 112, the exemplary rear brake 140, and the exemplary brake support 200, viewed from the same perspective. Figure 4As shown, the left frame portion 202 has a first axle opening 400, and the right frame portion 204 has a second axle opening 402. In some embodiments, the first axle opening 400 is a through hole, and the second axle opening 402 is threaded. To install the rear wheel hub assembly 112, a wheel hub 214 having a rear brake rotor 150 is arranged between the left frame portion 202 and the right frame portion 204. A shaft 216 is then inserted through the first axle opening 400, through the wheel hub 214 and the rear brake rotor 150, and screwed into the second axle opening 402. In other embodiments, the second axle opening 402 may also be a through hole. In such embodiments, a nut or other threaded fastener can be screwed onto the end of the shaft 216 located on the outside of the right frame portion 204.

[0049] As described above, due to the relatively long lengths of the left frame portion 202 and the right frame portion 204, and due to manufacturing tolerances, the first axle opening 400 and the second axle opening 402 may not be perfectly aligned. Therefore, bicycle manufacturers often enlarge the first axle opening 400 to allow the axle 216 to be slightly tilted or angled within it, compensating for any potential misalignment between the first and second axle openings 400 and 402. Known bicycles typically mount brake calipers to the left rear seat fork 208. However, because the rear hub assembly 112 (along with the rear brake rotor 150) is slightly off-axis relative to the frame 102, the brake pads may not be parallel to the rear brake rotor 150. Therefore, the user needs to manually adjust the position of the brake caliper using shims and spacers, a time-consuming and tedious process. As disclosed further in detail herein, the exemplary brake mount 200 establishes a strong or absolute axial and radial reference between the rear brake caliper 152 and the rear hub assembly 112, rather than the frame 102. This results in virtually no adjustability relative to the rear hub assembly 112. Therefore, the brake support 200 positions the rear brake caliper 152 more precisely relative to the rear brake rotor 150.

[0050] In this embodiment, the rear brake caliper 152 is connected to the bracket 220 by means of a set of threaded fasteners 404, 406 (e.g., bolts). In the illustrated embodiment, the bracket 220 includes eyelets 408, 410 (e.g., threaded eyelets), which may also be referred to as rear caliper supports or front caliper supports. Threaded fasteners 404, 406 can be inserted through openings in the rear brake caliper 152 and screwed into eyelets 408, 410 to connect the rear brake caliper 152 to the bracket 220. This allows the rear brake caliper 152 to be easily connected to and disconnected from the bracket 220. Any brake caliper with the same bolt-hole configuration can be connected to the bracket 220. Therefore, the bracket 220 is considered a universal brake support or adapter. In other embodiments, the rear brake caliper 152 can be connected to the bracket 220 by means of more or fewer threaded fasteners. Alternatively, the rear brake caliper 152 may be connected to the bracket 220 via other fastening mechanisms (e.g., rivets, latches, friction fits, etc.).

[0051] In the illustrated embodiment, the bracket 220 has a first opening 412, which may be referred to as an axle opening. The first opening 412 is used to receive the axle 216 of the rear wheel hub assembly 112. In particular, when the bracket 220 is mounted on the bicycle 100, the axle 216 extends through the first opening 412. Therefore, the first opening 412 forms a first contact point between the bracket 220 and the bicycle 100, and thus forms a first contact point between the rear brake caliper 152 and the bicycle 100. This first contact point may also be referred to as the rear bracket-bicycle attachment point.

[0052] In the illustrated embodiment, the bracket 220 includes a sleeve 414. The sleeve 414 extends from the outer-facing side of the bracket 220 and is coaxial with the first opening 412. When the bracket 220 is mounted on the bicycle 100, the sleeve 414 extends into the first axle opening 400, and the axle 216 extends through the sleeve 414. In the illustrated embodiment, the distal end 416 of the sleeve 414 is threaded. The brake mount 200 includes a nut 418. After the sleeve 414 is inserted (e.g., through) into the first axle opening 400, the nut 418 can be threaded (e.g., screwed onto) the distal end 416 of the sleeve 414. Thus, in this embodiment, the nut 418 is located on the outer side 421 of the frame 102, and the bracket 220 is located on the inner side 419 of the frame 102. In this embodiment, when the bracket 220 is mounted on the bicycle 100, the sleeve 414 extends through the first axle opening 400. However, in other embodiments, the sleeve 414 may be sized to extend only partially into the first axle opening 400, so that the distal end 416 is not outside the left frame portion 102. In such embodiments, the nut 418 may be at least partially disposed within the first axle opening 400. In some embodiments, the brake support 200 includes a washer 420 (e.g., a sleeve, spacer) disposed around the sleeve 414 and clamped between the bracket 220 and the left frame portion 202.

[0053] In the illustrated embodiment, the bracket 220 has a second opening 422, which may be referred to as a post opening. The brake support 200 includes a post 423 for attachment to the inner side 419 of the left frame portion 202, such that the post 423 extends inward. The second opening 422 is arranged around and attached to the post 423. In this embodiment, the post 423 is implemented as a bolt 424, referred to here as a bracket bolt 424. When assembled, the bracket bolt 424 extends through the second opening 422 and is screwed into the threaded opening 426 of the left rear upper fork 208. In some embodiments, the brake support 200 includes a sleeve 428 that can be arranged around the bracket bolt 424. The sleeve 428 increases the contact area between the bracket 220 and the bracket bolt 424, thereby increasing the contact area between the bracket 220 and the frame 102. The brake mount 200 includes means or devices for reducing the inner diameter of the second opening 422, thereby allowing the bracket 220 to be clamped onto the post 423. In this embodiment, the second opening 422 is implemented as a clamp, which will be shown in further detail herein. The bracket 220 includes a clamping bolt 430 that can be threadedly inserted (e.g., screwed) into the bracket 220 to clamp the bracket 220 onto a bracket bolt 424 (and a sleeve 428) at the second opening 422. In other embodiments, the brake mount 200 may include other structures to reduce the inner diameter of the second opening 422. Thus, the second opening 422 forms a second contact point between the bracket 220 and the bicycle 100, thereby forming a second contact point between the rear brake caliper 152 and the bicycle 100. This second contact point may also be referred to as the front bracket-bicycle attachment point.

[0054] Figure 5A This is a perspective view of an exemplary bracket 220 and an exemplary sleeve 414. In the illustrated embodiment, the bracket 220 has: a first side 500; a second side 502 opposite to the first side 500; and an outer peripheral edge 504 between the first side 500 and the second side 502. When the bracket 220 is attached to the bicycle 100, the first side 500 faces outward, and the second side 502 faces inward. A first opening 412 and a second opening 422 extend through the bracket 220 between the first side 500 and the second side 502. In some embodiments, the bracket 220 is a single unit part or component (e.g., an integral structure). For example, the bracket 220 may be machined from a single piece of metal (e.g., aluminum). In other embodiments, the bracket 220 may be constructed from a plurality of parts or components joined together.

[0055] In the illustrated embodiment, sleeve 414 extends from a first side 500 of bracket 220 and is coaxial with first opening 412. In this embodiment, sleeve 414 is integral with bracket 220. For example, bracket 220 and sleeve 414 may be constructed from a single unit part or component (e.g., an integral structure). Therefore, in this embodiment, first opening 412 extends through sleeve 414 and bracket 220. In some embodiments, bracket 220 and sleeve 414 are constructed from a metal such as aluminum. Additionally or alternatively, bracket 220 and sleeve 414 may be constructed from other materials. In other embodiments, sleeve 414 may be a separate part or component coupled to or arranged relative to bracket 220, in combination with... Figure 14 and Figure 15 An embodiment of the sleeve is disclosed. In the illustrated embodiment, the distal end 416 of the sleeve 414 is threaded. Nut 418 ( Figure 4 It can be screwed onto the far end 416 of the sleeve 414.

[0056] like Figure 5A As shown, bracket 220 has a gap 506 extending between a first side 500 and a second side 502, and between a second opening 422 and an outer peripheral edge 504. Bracket 220 also has a fastener opening 508 extending into bracket 220 and across gap 506. Clamping bolt 430 ( Figure 4 The bracket 220 can be inserted and screwed into the fastener opening 508. When the clamping bolt 430 is tightened, the size of the gap 506 decreases or closes, which reduces the size of the second opening 422, thereby clamping the bracket 220 to the bracket bolt 424 and / or the sleeve 428. Figure 4 Therefore, the second opening 422, the gap 506, and the fastener opening 508 form a clamp. In this embodiment, the second opening 422 is unthreaded. Instead, the second opening 422 is clamped to the bracket bolt 424 and / or the sleeve 428. This allows the bracket 220 to engage with the rear wheel hub assembly 112. Figure 4 Comparison of frame 102 ( Figure 4 Maintain stronger axial and radial references.

[0057] In the illustrated embodiment, the bracket 220 includes eyelets 408 and 410. Eyelets 408 and 410 are for receiving threaded fasteners 404 and 406. Figure 4 ) to the rear brake caliper 152 ( Figure 4 The 408 and 410 holes are connected to the bracket 220. The dimensions (e.g., having a specific diameter and / or thread size) and spacing of the holes can be determined according to general pliers standards, so that different types of pliers can be connected to the bracket 220.

[0058] Figure 5BThis is a side view of the exemplary bracket 220 and the exemplary sleeve 414. Figure 5B The figure shows a plane 510 extending into the diagram. This plane 510 represents the mounting plane where the bracket 220 connects to the bicycle 100, specifically at the first opening 412 and the second opening 422. Plane 510 bisects the first opening 412 and the second opening 422. Figure 5B As shown, the axes of the eyelets 408 and 410 intersect the plane 510 between the first opening 412 and the second opening 422. Thus, the second opening 422 (front bracket-bicycle attachment point) is radially outside the second threaded eyelet 410 (front caliper support) relative to the first opening 412 (rear bracket-bicycle attachment point). This reduces the contact between the second opening 422 and the bracket bolt 424 during braking compared to a configuration where the second threaded eyelet 410 (front caliper support) is radially outside the second opening 422 (second attachment portion). Figure 4 The load on the interface between ).

[0059] Figure 5C It is along Figure 5B A cross-sectional view of the exemplary bracket 220 and exemplary sleeve 414, taken along line AA (along plane 510). In the illustrated embodiment, the central axis 512 of the first opening 412 is parallel to the central axis 514 of the second opening 422. Therefore, the first opening 412 and the second opening 422 are parallel. When the bracket 220 is mounted with the rear wheel hub assembly, the central axis 512 of the first opening 412 is coaxial with or the same as the axis of rotation 218. Figure 2 ).

[0060] Figure 5D This is a top view of the exemplary bracket 220 and the exemplary sleeve 414. Figure 5D As shown, the bracket 220 is tilted (at an angle) or bent inward from the first opening 412 to the second opening 422. Therefore, the first opening 412 and the second opening 422 are axially offset. The first side 502 is axially offset by a distance L at the first opening 412 and the second opening 422. In some embodiments, the distance L is approximately 12 millimeters (mm) (e.g., ±1 mm). In other embodiments, the distance L may be greater than or less than 12 millimeters. Figure 5E It is along Figure 5D A cross-sectional view of an exemplary bracket 220 cut by line BB. Figure 5E Holes 408 and 410 extending into bracket 220 are shown. Figure 5F It is along Figure 5D A cross-sectional view of an exemplary bracket 220 cut by line CC. (See attached image.) Figure 5F As shown, the second opening 422 is relative to the rotation axis 218 ( Figure 2 ) and / or the first opening 412 ( Figure 5A ) central axis 510 ( Figure 5C ) extends in the radial direction. This allows bracket 220 to be positioned relative to bracket bolt 424 ( Figure 4 Radial positioning or movement to maintain the rear wheel hub assembly 112 ( Figure 4 A strong or absolute reference. For example... Figure 5F As shown, the fastener opening 508 extends into the bracket 220 and spans the gap 506.

[0061] Figure 6 This is a top view of the wheel hub assembly 112, rear brake 140, and brake mount 200 on the frame 102. (See attached image.) Figure 6 As shown, the brake support 200 positions the rear brake caliper 152 inside the left frame portion 202 and aligns it with the rear brake rotor 150. In the illustrated embodiment, the rear brake caliper 152 has an inner brake pad 600 and an outer brake pad 602. In some embodiments, both brake pads 600 and 602 are movable. In other embodiments, one of the brake pads 600 and 602 is fixed, and the other is movable. When the rear brake caliper 152 is actuated, one or both of the brake pads 600 and 602 move to engage with the rear brake rotor 150. The brake support 200 axially aligns the rear brake caliper 152 with the rear brake rotor 150 such that the brake pads 600 and 602 are parallel to and located on opposite sides of the rear brake rotor 150. The brake support 200 has a stronger axial reference to the rear wheel hub assembly 112 than to the frame 102. Therefore, if the rear wheel hub assembly 112 shifts axially relative to the frame 102, the brake pads 600, 602 remain axially aligned with the rear brake rotor 150. On known bicycles, the rear brake caliper has a stronger reference to the frame 102. Therefore, if the rear wheel hub assembly 112 shifts axially relative to the frame 102, the brake caliper (and thus the brake pad) will become offset from the rear brake rotor 150. In some cases, a brake pad may remain straddling the rear brake rotor 150.

[0062] Figure 6 The main load paths are marked. For example... Figure 6 As shown, the contact area between bracket 220 and bracket bolt 424 passes through or is close to the plane of the rear brake rotor 150. In other words, the front contact between bracket 220 and the left frame portion 202 is substantially axially aligned with the rear brake rotor 150. This minimizes elastic deformation within the main load-bearing portion or component and significantly improves torsional load on the main load-bearing element. This configuration also helps reduce vibration and noise compared to known brake mount designs.

[0063] Figure 7This is a side view (facing inwards) of the wheel hub assembly 112, rear brake 140, and brake support 200 on the frame 102. The brake support 200 radially aligns the rear brake caliper 152 with the rear brake rotor 150, such that the brake pads 600, 602 ( Figure 6 The brake pads 600 and 602 are radially aligned with the brake rails of the rear brake rotor 150 (relative to the axis of rotation 218 of the rear brake rotor 150). The radial reference of the brake support 200 to the rear wheel hub assembly 112 is stronger than its radial reference to the frame 102. Therefore, if the rear wheel hub assembly 112 is displaced radially relative to the frame 102, the brake pads 600 and 602 remain radially aligned with the brake rails on the rear brake rotor 150.

[0064] The braking force from the rear brake caliper 152 is applied tangentially to the bracket bolt 424, as indicated by the arrow marked "force". Figure 7 The distances D1, D2, and D3 are marked. D1 is the radial distance between the rotation axis 218 and the bracket bolt 424 (front bracket-bicycle attachment point). In some embodiments, distance D1 is at least approximately 110 mm (e.g., ±1 mm). In other embodiments, distance D1 may be less than 110 mm. D2 is the radial distance between the tangents extending through the rotation axis 218 and the second threaded fastener 406 (front caliper support). D3 is the radial distance between the tangents extending through the first threaded fastener 406 (front caliper support) and the second threaded fastener 408 (rear caliper support). Figure 7 As shown, D1 is larger than D2. Therefore, the front bracket-bicycle attachment point (at bracket bolt 424) is further radially than the front caliper support (second threaded fastener 406). This results in a smaller load on the front bracket-bicycle attachment point (at bracket bolt 424) compared to when the front bracket-bicycle attachment point is closer to the axis of rotation 218. In some embodiments, to minimize the support load in the tangential direction, the distance D1 is approximately 115 to 125 mm (e.g., ±5 mm). In other embodiments, the distance D1 can be larger or smaller.

[0065] Figure 8 It is along Figure 7 A cross-sectional view of the frame 102, rear wheel hub assembly 112 and brake support 200 cut along line DD. Figure 8 The rear brake caliper 152 is not shown. For example... Figure 8As shown, the rear wheel hub assembly 112 includes an inner spindle 800. A shaft 216 extends through and engages with the inner spindle 800 (via an interference fit). The rear wheel hub 214 rotates about the inner spindle 800 via bearings 802, 804. A rear brake rotor 150 is rigidly coupled to the rear wheel hub 214 (e.g., via one or more fasteners). Thus, the rear brake rotor 150 rotates together with the rear wheel hub 214 about the inner spindle 800 and the shaft 216. In the illustrated embodiment, the hub assembly 112 includes a hub end cap 806 located at the end of the rear wheel hub 214.

[0066] Figure 9 yes Figure 8 An enlarged view of annotation portion 808. In the illustrated embodiment, bracket 220 is arranged inside the left frame portion 202 of the frame 102. A sleeve 414, connected to or integral with bracket 220, extends through a first shaft opening 400 in the left frame portion 202. In the illustrated embodiment, sleeve 414 is longer than the first shaft opening 400. Thus, a portion of sleeve 414 is inside the left frame portion 202, and the distal end 416 of sleeve 414 is outside the left frame portion 202. Shaft 216 extends through sleeve 414. Therefore, in this embodiment, shaft 216 does not contact the left frame portion 202.

[0067] In the illustrated embodiment, the second side 502 (the inward-facing side) of the bracket 220 engages with the hub end cap 806. The sleeve 414 has an outer surface 900 and an inner surface 902. The inner surface 902 of the sleeve 414 has a shoulder 904 (e.g., a boss, step, etc.) near its distal end 416. In the illustrated embodiment, the shaft 216 has a head 906 that engages with the shoulder 904. When the shaft 216 is tightened (e.g., screwed into the second shaft opening 402...), Figure 4 The bracket 220 and sleeve 414 are axially clamped between the head 904 of the shaft 216 and the rear wheel hub end cap 806. This axially fixes the bracket 220 and sleeve 414 relative to the rear wheel hub 214, the shaft 216, and the rest of the rear wheel hub assembly 112 (including the rear brake rotor 150). The shaft 216, bracket 220, sleeve 414, and wheel hub end cap 806 can be constructed of metal. This metal-metal interface and dimensional surface characteristics (e.g., large surface area) establish a strong planar reference between the shaft 216, sleeve 414, and wheel hub end cap 806. This results in a strong axial reference between these parts. Therefore, even if the rear wheel hub assembly 112 is misaligned with the frame 102, the bracket 220 remains in the same axial position relative to the rear wheel hub assembly 112, and thus, the rear brake caliper 152 ( Figure 1 It remains in the same axial position relative to the rear brake rotor 150.

[0068] In the illustrated embodiment, nut 418 is threadedly connected to the distal end 416 of sleeve 414. Washer 420 is disposed between the first side 500 of bracket 220 and the inner side 419 of left frame portion 202. When nut 418 is tightened, frame 102, washer 420, bracket 220, and rear wheel hub assembly 112 are axially clamped or secured. In some embodiments, washer 420 is constructed of a compliant material (e.g., a resiliently deformable material). For example, washer 420 may be constructed of plastic and / or rubber. Therefore, washer 420 may be slightly compressed when nut 418 is tightened. The surface contact area of ​​washer 420 with adjacent parts is also relatively small. This limited contact and the plastic-metal interface result in a weak planar reference between wheel hub assembly 112 and frame 102, and therefore a weak axial reference between bracket 220 and frame 102. However, even if the rear wheel hub assembly 112 is axially displaced or moved relative to the frame 102, the bracket 220 remains axially fixed relative to the rear wheel hub assembly 112, which ensures that the rear brake caliper 152 and the rear brake rotor 150 remain axially aligned.

[0069] In some embodiments, the outer peripheral edge 908 of the washer 420 is tapered or inclined, such as... Figure 9 As shown in the diagram. The tapered shape increases the surface pressure on the washer 420, making it easier to deform during installation. The tapered shape also reduces the influence of the frame 102, so the bracket 220 and sleeve 414 can maintain their orientation relative to the rear wheel hub 214 and axle 216. In other embodiments, the washer 420 may have different shapes. For example, briefly refer to... Figure 10 , Figure 10 An alternative washer 1000 for use with the brake support 200 is shown. In the illustrated embodiment, the washer 1000 has a concave or spherical surface 1002 that mates with or corresponds to the first side 500 of the bracket 220. This spherical shape allows the bracket 220 to rotate or tilt relative to the frame 102 (e.g., in one or more directions), thus maintaining a weaker axial reference to the frame 102. In other embodiments, the washer may not be used. Instead, the first side 500 of the bracket 220 may directly contact the inner side 419 of the left frame portion 202.

[0070] Go back to reference Figure 9The exemplary brake support 200 also establishes a strong radial reference between the bracket 220 and the rear wheel hub assembly 112. The sleeve 414 is relatively long, thus providing a wider support width with respect to the shaft 216. The shaft 216 and the sleeve 414 (and therefore the bracket 220) can have a relatively tight fit. For example, the inner surface 902 of the sleeve 414 and the outer surface 910 of the shaft 216 can form a transition fit (sometimes called a sliding fit) or an interference fit (sometimes called a press fit or friction fit). The wider support width and fit result in a relatively strong radial reference between the bracket 220 and the rear wheel hub assembly 112. Thus, the rear brake caliper 152 ( Figure 4 The sleeve 414 remains in the same radial position relative to the rear brake rotor 150. However, the sleeve 414 can have a relatively loose fit in the first axle opening 400. For example, the first axle opening 400 and the sleeve 414 can form a clearance fit. This loose fit with a narrow support width provides a weaker tolerance compensation reference. In particular, this allows some radial movement between the axle / sleeve and the frame 102, which is advantageous when mounting the hub assembly, as the first axle opening 400 and the second axle opening 402 may not be perfectly aligned. Therefore, in some embodiments, the radial fit between the first axle opening 400 and the axle 216 is tighter than the radial fit between the sleeve 414 and the frame 102. Furthermore, in some embodiments, the axial length of the radial fit between the first axle opening 400 and the axle 216 is longer than the axial length of the radial fit between the sleeve 414 and the frame 102.

[0071] Figure 11 It is along Figure 7 The diagram shows a cross-sectional view of the bracket 220 and bracket bolt 424, cut along line EE. In the illustrated embodiment, the bracket bolt 424 extends through a second opening 422 in the bracket 220 and screws into a threaded opening 426 in the left rear upper fork 208. A sleeve 428 is arranged around the bracket bolt 424. In the illustrated embodiment, a portion of the sleeve 428 extends into the left rear upper fork 208. In other embodiments, the sleeve 428 may not extend into the left rear upper fork 208. Figure 12 It is along Figure 6 A cross-sectional view of bracket 220 and bracket bolt 424 cut by line FF.

[0072] When bracket 220 is installed, and before clamping bolt 430 is tightened, bracket 220 can move axially and radially along sleeve 428. For example, as Figure 11 As shown, the portion of the bracket bolt 424 and sleeve 428 extending from the left rear upper fork 208 is longer than the width of the bracket 220. This allows the bracket 220 to be positioned at different axial locations along the bracket bolt 424 and sleeve 428. Furthermore, as... Figure 12 As shown, the second opening 422 in the bracket 220 is relative to the rotation axis 218 ( Figure 2 ) and / or the first opening 412 ( Figure 4 ) central axis 510 ( Figure 5C The bracket 220 extends in the radial direction. This allows the bracket bolt 424 and sleeve 428 to be positioned at different radial locations. As a result, the bracket 220 has a weaker axial and radial reference to the frame 102, which allows the bracket 220 to maintain a stronger axial and radial reference to the rear wheel hub assembly 112.

[0073] The following is combined with Figure 9 , Figure 11 and Figure 12 An exemplary method for installing the rear wheel hub assembly 112, the rear brake 140, and the bracket 220 is disclosed. First, refer to... Figure 9 The washer 420 can be placed around the sleeve 414. Then, the bracket 220 can be positioned inside the left frame portion 202 and moved toward the left frame portion 202 to insert the sleeve 414 into the first axle opening 400. Before or after installing the bracket 220, the rear brake caliper 152 ( Figure 1 The rear brake rotor 150 is then connected to the bracket 220. The rear brake rotor 150 is then connected to the rear wheel hub 214 (e.g., via one or more fasteners, via a spline connection, etc.), and the rear wheel hub 214 is positioned between the left frame portion 202 and the right frame portion 204, such that the bracket 220 is arranged between the hub end cap 806 and the left frame portion 202. The shaft 216 is then passed through the sleeve 414 and the first shaft opening 400, and through the rear wheel hub 214 into the right frame portion 204. Figure 4 The second shaft opening 402 in ) Figure 4 Then, the shaft 216 can be tightened to axially secure the bracket 220 and the rear wheel hub 214, thereby axially and radially securing the bracket 220 and the rear wheel hub assembly 112. The nut 418 can then be screwed onto the distal end 416 of the sleeve 414. After securing the bracket 220 to the rear wheel hub assembly 112, the bracket 220 can be connected to the left rear upper fork 208 via the post 423. (See reference) Figure 11 and Figure 12The bracket bolt 424 is inserted through the sleeve 428, and then the bracket bolt 424 and sleeve 428 are inserted through the second opening 422 of the bracket 220 and screwed into the left rear upper fork 208. The inner diameter of the second opening 422 is larger than the outer diameter of the post 423 (i.e., the sleeve 428). In some embodiments, there is a gap between the inner diameter of the second opening 422 and the sleeve 428 before the clamping bolt 430 is tightened. In other embodiments, the inner surface of the second opening 422 may contact the sleeve 428. In either case, at this time, for example, if the nut 418 is further tightened or loosened, the bracket 220 can still move (e.g., slide) relative to the bracket bolt 424 in the axial and radial directions. The clamping bolt 430 can then be screwed into the bracket 220 and tightened. This reduces the inner diameter of the second opening 422 to clamp the bracket 200 onto the bracket bolt 424. In some embodiments, the clamping bolt 430 is tightened to such an extent that the bracket 220 is clamped to the bracket bolt 424 and substantially fixed in the axial and radial directions. In other embodiments, the clamping bolt 430 may be tightened tightly, but still allows the bracket 220 to slide axially and radially relative to the bracket bolt 424. In other embodiments, the brake support 200 may include one or more other mechanisms for reducing the inner diameter of the second opening 422 and / or increasing the outer diameter of the post 423 to clamp the bracket 220 to the post 423. For example, the bracket 220 may include a ratchet / ratchet or latching mechanism to close the gap 506 ( Figure 5F In other embodiments, the brake support 200 may include one or more conical sleeves that can be inserted into the second opening 220 to reduce the size of the second opening 220 and secure the bracket 220 to the post 423. In other embodiments, the bracket 220 may not be clamped at all. Instead, the bracket 220 may float on the bracket bolt 424 and the sleeve 428.

[0074] During braking, the force from the rear brake caliper 152 is transmitted from the bracket 220 to the bracket bolt 424, and thus to the frame 102. For example... Figure 11 and Figure 12 As shown, sleeve 428 increases the contact area between bracket 220 and bracket bolt 424, which distributes the load on bracket bolt 424. Many bicycles include standardized threaded openings that can receive bolts of a certain size. Therefore, sleeve 428 allows brake mount 200 to utilize the same opening and bolt while advantageously increasing the contact area. However, in other embodiments, bolts or struts of a larger diameter can be used instead of sleeves. In some embodiments, sleeve 428 is made of a compliant material (e.g., plastic, rubber, or...) ) is constructed.

[0075] Figure 13An alternative connection type between bracket 220 and left rear upper fork 208 is shown. Figure 13 In this embodiment, post 1300 is coupled to and extends inside the left rear upper fork 208. In some embodiments, post 1300 and left rear upper fork 208 are integral. In the illustrated embodiment, sleeve 1302 is arranged around post 1300, which increases the contact area between bracket 220 and post 1300. In some embodiments, sleeve 1302 is made of a compliant material (e.g., rubber or plastic). In some embodiments, threaded fastener 1304 is screwed into the end of post 1300 to retain sleeve 1302 on post 1300 and prevent bracket 220 from moving inward away from post 1300. In some embodiments, when threaded fastener 1304 is tightened, sleeve 1302 is axially compressed and therefore expands in the radial direction. Sleeve 1302 can expand into bracket 220, which helps to clamp bracket 220 to post 1300 in the radial direction. In other embodiments, sleeve 1302 and / or threaded fastener 1304 may not be used. Instead, bracket 220 may directly contact post 1300.

[0076] Although in the embodiments disclosed above, the sleeve 414 is integral with or connected to the bracket 220, in other embodiments, the sleeve 414 may be separate from the bracket 220. Figure 14 An embodiment is shown where the sleeve 414 is separated from the bracket 220. In this embodiment, the sleeve 414 has an enlarged first end 1400. The sleeve 414 can be inserted from the second side 502 of the bracket 220 through a first opening 412 in the bracket 220 until the first end 1400 of the sleeve 414 engages with the second side 502 of the bracket 220.

[0077] Figure 15 It is installed together with the rear wheel hub assembly 112. Figure 14 A cross-sectional view of the bracket 220 and the sleeve 414, the cross-section being similar to... Figure 8 and Figure 9 The view in the image. For example... Figure 15As shown, sleeve 414 is arranged in the first opening 412 of bracket 220. The inner surface 1500 of bracket 220 engages with the outer surface 900 of sleeve 414. In the illustrated embodiment, the outer surface 900 of sleeve 414 has a first shoulder 1502 near the first end 1400. The inner surface 1500 of the first opening 412 in bracket 220 has a correspondingly shaped second shoulder 1504. The first shoulder 1502 of sleeve 414 engages with the second shoulder 1504 of bracket 220. This prevents bracket 220 from moving inward relative to sleeve 414, thereby preventing bracket 220 from moving inward relative to shaft 216. Sleeve 414 fits tightly in the first opening 412 of bracket 220, for example via an interference fit. This establishes a strong radial reference between bracket 220 and rear wheel hub assembly 112.

[0078] like Figure 15 As shown, sleeve 414 extends outward from the first side 500 of bracket 220. Sleeve 414 extends through the first shaft opening 400 of the left frame portion 202. Washer 1506 is arranged around sleeve 414 between bracket 220 and left frame portion 202. In this embodiment, washer 1506 is wider than washer 420. Washer 1506 has a beveled edge. When shaft 216 and nut 418 are tightened, bracket 220 is axially fixed to hub assembly 112. This is between bracket 220 and rear hub assembly 112 and therefore between rear brake caliper 152 ( Figure 1 A strong axial reference was established between the rear brake rotor 150 and the rear brake rotor 150.
