Description

BACKGROUNDTechnical FieldThis disclosure relates generally to a disc brake caliper for muscle-powered vehicles (or human-powered vehicles) such as bicycles.Background InformationIn general, there are several types of brake devices currently available on the market for muscle-powered vehicles, e.g. bicycles. Examples of some common bicycle brake devices include rim brakes and disc brakes. Disc brakes have become increasingly popular for muscle powered vehicles such as bicycles. In particular, disc brakes provide considerable braking performance relative to the braking force applied to a brake lever or pedal, as compared to rim brakes. Moreover, disc brake systems typically provide a high level of brake consistency under all weather and driving conditions. Disc brakes may be actuated either by cable or hydraulically.SUMMARYIn general, the present disclosure relates to various features of a disc brake caliper for a muscle powered vehicle. The term "human-powered vehicle" (or "human-powered vehicle") as used herein refers to a vehicle that can be propelled at least by human driving force to produce propulsion, but does not include a vehicle that uses only driving force other than human force. In particular, a vehicle that uses only an internal combustion engine as a driving force does not belong to muscle-powered vehicles.

It will be apparent to those skilled in the muscle-powered vehicle (e.g., bicycles) art from this disclosure that the following descriptions of the embodiments are provided for illustration only and not for the purpose of limiting the invention as claimed in the appended claims and their equivalents.Referring to FIGS. 1 and 2, there is first illustrated a muscle-powered vehicle V (e.g., a bicycle) equipped with a brake system 10 (e.g., a bicycle brake system) according to a first embodiment. Here, the muscle-powered vehicle V is illustrated as an electric assist bicycle. However, the brake system 10 may be used for other types of muscle-powered vehicles, such as a motor scooter, an elliptical bicycle, a tricycle, a mountain bike, a cyclocross bicycle, a racewheel, a citywheel, a cargo wheel, and a recumbent wheel.As illustrated in FIG. 1, the muscle-powered vehicle V includes a vehicle body VB (e.g., a frame such as a bicycle frame) supported by a rear wheel RW and a front wheel FW. The vehicle body VB substantially includes a front frame body FB and a rear frame body RB (a swing arm). The vehicle body VB is also provided with a front fork FF and a handlebar H for steering the muscle-powered vehicle V. The muscle-powered vehicle V further includes a caliper support SP coupled to the seat tube of the vehicle body VB to support a bicycle seat S at the upper end.The bicycle B also includes a drive train DT. Here, the drive train DT is, for example, a chain drive including a crank C, at least one front sprocket FS, a plurality of rear sprockets RS, and a chain CN. The crank C includes a crank axis CA 1 and a pair of crank arms CA 2. The crank axle CA 1 is rotatably supported on the front frame body FB. The crank arms CA 2 are provided at opposite ends of the crank axle CA 1. A pair of pedals PD are rotatably coupled to the distal end of each of the crank arms CA 2. The front sprocket FS is provided on the crank C and rotates integrally with the crank axle CA 1. The rear sprocket RS is provided at a hub of the rear wheel RW. The chain CN runs around the front sprocket FS and the rear sprockets RS. A human driving force is applied to the pedals PD by a rider of the bicycle B, so that the driving force is transmitted to the rear wheel RW via the front sprocket FS, the chain CN, and the rear sprockets RS. Although the powertrain DT is illustrated as a chain drive type of powertrain, the powertrain DT may be selected from any type of powertrain and may be a belt drive type or a shaft drive type. Here, the bicycle B further includes a drive unit DU configured to apply a driving force to the crank axle CA 1 of the muscle-powered vehicle V.Referring first to FIG. 2, a portion of the muscle-powered vehicle V equipped with the brake system 10 is illustrated. The disc brake system 10 includes a disc brake caliper 12 and a brake operating device 14 according to the first embodiment. The disc brake caliper 12 is provided for a muscle-powered vehicle V. Basically, the disc brake caliper 12 comprises a hydraulic caliper body 16. Here, the disc brake caliper 12 comprises a mechanical caliper body 18. Specifically, a hydraulic hose 20 is operatively coupled between the brake operating device 14 and the hydraulic caliper body 16. On the other hand, the caliper mechanical body 18 is configured to be actuated by a cable 21. Specifically, the cable 21 is operatively coupled between the brake operating device 14 and the brake caliper mechanical body 18. The disc brake caliper 12 is configured to selectively grip a disc brake rotor 22 fixedly attached to a hub of the wheel RW (e.g., a bicycle wheel) (decelerating and / or stopping rotation). As discussed below, the hydraulic caliper body 16 and the mechanical caliper body 18 are typically selectively used to grip (slow or stop rotation) a disc brake rotor 22. A user can individually operate the hydraulic caliper body 16 and the mechanical caliper body 18 using the brake operating device 14. More specifically, the hydraulic caliper body 16 is typically used during travel to slow or stop rotation of the wheel RW, while the mechanical caliper body 18 is typically used when the muscle powered vehicle V is parked to prevent rotation of the wheel RW. Thus, the mechanical caliper body 18 here constitutes a parking brake for the muscle-powered vehicle V.As seen in FIG. 2, the disc brake caliper 12 is fixed to the vehicle body VB (e.g., a frame such as a bicycle frame) of the muscle-powered vehicle V with a bracket 23 and a pair of fixing bolts 24 (i.e., frame fasteners). Specifically, the hydraulic caliper body 16 includes a coupling portion 25. the coupling portion 25 is configured to couple the hydraulic caliper body 16 to the vehicle body VB of the muscle-powered vehicle V. Here, the coupling portion 25 includes, for example, a first coupling hole 25A and a second coupling hole 25B. The first coupling hole 25A and the second coupling hole 25B are through holes for receiving the fastening bolts 24 therethrough. The first coupling hole 25A and the second coupling hole 25B are preferably elongated holes to allow some displacement of the hydraulic caliper body 16 relative to the vehicle body VB. The caliper mechanical body 18 is configured to be coupled to the vehicle body VB via the coupling portion 25 of the caliper hydraulic body 16. In other words, the caliper mechanical body 18 is not directly attached to the vehicle body VB. Rather, the mechanical caliper body 18 is supported by the hydraulic caliper body 16 on the vehicle body VB. Here, the mechanical caliper body 18 is disposed on an upstream side of the hydraulic caliper body 16 relative to a rotational direction R 1 of the rotor 22.As seen in FIGS. 2-4, the brake actuator 14 is generally configured to actuate the disc brake caliper 12 in a conventional manner to forcibly grip the disc brake rotor 22 and stop rotation of the wheel RW. Here, the brake operating device 14 in the first embodiment substantially includes a base member 26 having a link clamp 27, a first brake lever 28, and a second brake lever 30. the first brake lever 28 is pivotally supported on the base member 26 between a rest position (FIG. 2 ) and an activated position (FIG. 3 ). The first brake lever 28 is biased by a first return spring toward the rest position corresponding to a non-braking or brake release position. Similarly, the second brake lever 30 is pivotally mounted to the base member 26 between a rest or unactuated position (FIG. 2 ) and an activated or actuated position (FIG. 4 ). The second brake lever 30 is also biased by a second return spring toward the rest position corresponding to a non-braking or brake release position.In the first embodiment, as shown in FIGS. 2 to 4, the brake operating device 14 is mounted on the handlebar H (i.e., a part of the muscle-powered vehicle V, namely, a part of the bicycle body). However, the brake operating device 14 may be mounted on other parts of the muscle-powered vehicle V as needed and / or desired. In the illustrated embodiment, the brake operating device 14 is connected to the muscle-powered vehicle V via the handle clamp 27 which is an example of a fastening structure. The link clamp 27 is a pipe clamp with a hinge. Since hinged pipe clamps are well known, the handlebar clamp 27 (i.e., the attachment structure) will not be discussed and / or illustrated in detail. The handle clamp 27 (i.e., the attachment structure) may also be referred to as a handle mounting structure in the illustrated embodiment.Here, the base member 26 includes a first base part 26A and a second base part 26B. At this time, the second base part 26B is fixedly mounted on the handle clamp 27, and the first base part 26A is detachably mounted on the second base part 26B. In this way, the first base portion 26A and the first brake lever 28 can be removed from the second base portion 26B. Alternatively, the first base portion 26A and the second base portion 26B may be mounted on separate mounting structures. In this manner, the first brake lever 28 may be mounted on the handlebar H at a location spaced from the second base part 26B or at another location on the vehicle body VB.Here, the first brake lever 28 is a parking brake lever, while the second brake lever 30 is used during travel. In other words, the first brake lever 28 is configured to be operated by a user so that the first brake lever 28 can be locked in the operated position (FIG. 3 ) to maintain the disc brake caliper 12 in a braking state even after the first brake lever 28 has been released by the user. Here, the brake operating device 14 is provided with a locking device 31 for locking the first brake lever 28 in the operated position. On the other hand, the second brake lever 30 is configured to be operated by a user to temporarily maintain the disc brake caliper 12 in the braking state while the second brake lever 30 is maintained by the user in the operated state. Once the user releases the second brake lever 30, the second brake lever 30 is automatically moved to the rest position (i.e., the non-braking position).Referring to FIGS. 3 and 4, the locking device 31 includes a locking member 32 movable between an unlocked and a locked position. When the locking member 32 is in the unlocked position (see FIG. 2 ), the first brake lever 28 is in the rest position (i.e., the unactuated position or non-braking position). When the locking member 32 is in the locked position, as seen in FIG. 3, the first brake lever 28 is in the actuated position (i.e., the braking position). Preferably, the locking device 31 includes a biasing member 34 that biases the locking member 32 toward the unlocked position. Thus, when the first brake lever 28 is moved from the rest position (FIG. 2 ) to the braking position (FIG. 3 ), the locking member 32 is moved by the user to the locked position to block movement of the first brake lever 28 back to the rest position. The biasing member 34 is, for example, a coiled compression spring disposed about the locking member 32 to bias the locking member 32 toward the unlocked position. In the locked position, the locking member 32 has a stop that comes / stands in contact with the first brake lever 28 to prevent the first brake lever 28 from moving to the rest position. More specifically, the stopper of the lock member 32 is pinched between the first brake lever 28 and the base member 26 by the first return spring of the first brake lever 28. The first brake lever 28 may be released to move toward the rest position by operating the first brake lever 28 to release the pressure applied to the locking member 32 so that the biasing force of the biasing member 34 moves the locking member 32 to the unlocked position.As mentioned above and as seen in FIG. 2, the first brake lever 28 is coupled to the mechanical caliper body 18 via the cable 21. As seen in FIGS. 7 and 8, the cable 21 includes an outer sheath 21 aand an inner wire 21 b. Optionally, a drum adjuster for adjusting cable tension may be provided between the caliper mechanical body 18 and the outer sheath 21 aof the cable 21. The outer shell 21 aextends between a part of the base member 26 and a part of the caliper mechanical body 18. the inner wire 21 bis fixedly coupled to the first brake lever 28 and a part of the caliper mechanical body 18, as described below.As seen in FIG. 2, the second brake lever 30 is coupled to the hydraulic caliper body 16 via the hydraulic hose 20. In particular, the hydraulic caliper body 16 includes a hydraulic hose connector 38. The hydraulic hose 20 includes a hollow bolt hose end piece 40 in fluid communication with the hydraulic caliper body 16 via the hydraulic hose connector 38. As seen in FIGS. 5 and 6, the other end of the hydraulic hose 20 is in fluid communication with the base member 26 via a hose fitting 42 that is screwed into a threaded hole of the base member 26.As seen in FIGS. 5 and 6, the second base part 26B includes a master cylinder 46 and a hydraulic fluid reservoir 48. the brake operating device 14 further includes a piston 50 movably disposed in a master cylinder bore 46 aof the master cylinder 46. The master cylinder 46 also has an outlet port 46 bfor supplying hydraulic fluid to the brake caliper hydraulic body 16 via the hydraulic hose 20. More specifically, the piston 50 moves linearly within the master cylinder bore 46 awhen the second brake lever 30 is pivoted relative to the second base portion 26B from the rest position (FIG. 2 ) to the actuated position (FIG. 4 ). Thus, the second brake lever 30 is operatively coupled to the piston 50 to pressurize the hydraulic fluid in the master cylinder bore 46 aand urge the hydraulic fluid through the outlet port 46 binto the hydraulic hose 20 toward the hydraulic caliper body 16. The brake operating device 14 further comprises a push rod or connecting rod 52 which brings the second brake lever 30 into operative connection with the piston 50. In this way, for example, the second brake lever 30 is coupled to the piston 50 to move the piston 50 within the master cylinder bore 46 a. The brake operating device 14 further includes a biasing member 54 (e.g., a compression coil spring) that biases the piston 50 to its initial (rest or unactuated) position and that also biases the second brake lever 30 to its rest position (i.e., no external force is applied to the second brake lever 30), as seen in FIG. 5.

Specifically, the first hydraulic piston 68 and the second hydraulic piston 70 are configured to move relative to the hydraulic caliper body 16 in response to the operation of the second brake lever 30. Thus, the first hydraulic piston 68 and the second hydraulic piston 70 are configured to move the first brake pad 65A and the second brake pad 65B to contact the disc brake rotor 22 from the rest position (i.e., the non-braking position) to the operated position (i.e., the braking position) in response to the operation of the second brake lever 30.

Specifically, the intermediate member 381 includes a stopper portion 81 dfor abutting an end of the biasing member 88, and the other end of the biasing member 88 abuts an inner surface of the caliper housing 73. In the illustrated embodiment, the biasing member 88 is, for example, a coiled compression spring that is compressed during a braking operation. Thus, the biasing member 88 acts as a return spring to return the intermediate member 81 to the unactuated position.Referring to FIGS. 27 to 30, the cam portion 81 bof the intermediate member 81 includes a cam surface 89. The cam surface 89 is configured to come / be in contact with the mechanical piston 78 during a braking operation in response to the movement of the cable 21 and move along the mechanical piston axis A 3 when the intermediate member 81 pivots about the pivot axis A 4. Preferably, as in the first embodiment, the intermediate member 81 is configured to generate a variable stroke speed of the mechanical piston 78 relative to a stroke of the cable 21 when the intermediate member 81 moves relative to the caliper mechanical body 18. Alternatively, the intermediate member 81 may be configured to generate a constant stroke speed of the mechanical piston 78 relative to a stroke of the cable 21 when the intermediate member 81 moves relative to the caliper mechanical body 18. In the first embodiment, the cam surface 89 is configured to generate a variable stroke speed of the mechanical piston 78 relative to a stroke of the cable 21 when the intermediate member 81 moves relative to the caliper mechanical body 18.The cam surface 89 of the intermediate member 81 has a first cam surface 89a configured to move the mechanical piston 78. The disc brake caliper 12 further includes a first roller member 90. the first roller member 90 is disposed between the mechanical piston 78 and the first cam surface 89 a. In the first embodiment, the first cam surface 89a is a curved or arcuate groove and the first roller member 90 is a ball.Preferably, the cam surface 89 of the intermediate member 81 has a second cam surface 89b as in the first embodiment. The second cam surface 89 bis configured to move the mechanical piston 78. The disc brake caliper 12 further includes a second roller member 91. the second roller member 91 is disposed between the caliper mechanical body 18 and the second cam surface 89 b. In the first embodiment, the second cam surface 89 bis a curved or arc-shaped groove, and the second roller member 91 is a ball.When the intermediate member 81 has both the first cam surface 89 aand the second cam surface 89 bas in the first embodiment, the first cam surface 89 ais configured to move the mechanical piston s 78 at a first piston operating speed, while the second cam surface 89 bis configured to move the mechanical piston 78 at a second piston operating speed. The first piston actuation speed is greater than the second piston actuation speed. In the first embodiment, the first cam surface 89a and the second cam surface 89b abut each other to form a continuous curved or arcuate groove curved about the axis A3 of the mechanical piston. The first cam surface 89 aand the second cam surface 89 bare inclined with respect to a mechanical piston moving direction D 1. Thus, the first cam surface 89a and the second cam surface 89b are ramp-shaped. The first cam surface 89a has a first inclination θ1 and the second cam surface 89b has a second inclination θ2. The first inclination θ 1 is different from the second inclination θ 2.In this structure of the first embodiment, as schematically illustrated in FIGS. 29 and 30, the mechanical piston 78 is configured to be moved, during a braking operation, as the intermediate member 81, by the first cam surface 89 atoward the rotor 22 from a rest position RPto a first position P 1 along a first movable range X 1. Thus, during the first range of motion X 1 of the braking operation, the mechanical piston 78 moves at the first piston operating speed. The mechanical piston 78 is configured to be moved further toward the rotor 22 from a second position P 2 to a third position P 3 along a second movement range X 2 during the braking operation as the intermediate member 81 by the second cam surface 89 b. The second movement range X 2 is located after the first movement range X 1. Therefore, during the second moving range X 2 of the braking operation, the mechanical piston 78 moves at the second piston operation speed. Because the first piston operating speed is greater than the second piston operating speed, the mechanical piston 78 quickly moves into engagement with the rotor 22 during the first range of motion X 1 of the braking operation. Although the first brake lever 28 is then moved at the same speed, the mechanical piston 78 moves more slowly when a braking force is applied to the rotor 22 during the second range of motion X 2 of the braking operation.Basically, during a braking operation of the caliper mechanical body 18, a user operates the first brake lever 28 to pull the inner wire 21 bof the cable 21 with respect to the caliper mechanical body 18. By pulling the inner wire 21 bof the cable 21, the intermediate member 81 is rotated about the pivot axis A 4. The rotation of the intermediate member 81 causes the cam portion 81 bto linearly move the mechanical piston 78 along the mechanical piston axis A 3. The linear movement of the mechanical piston 78 causes the auxiliary brake pad 79 to engage the rotor 22 to apply a braking force to the rotor 22.FIGS. 31 and 32 show a disc brake caliper 112 according to a second embodiment. The disc brake caliper 112 includes the hydraulic caliper body 16 of the first embodiment and a modified mechanical caliper body 118.

The part 194 includes a contact surface 194 a. The contact surface 194 ais configured to slidingly contact / be in contact with the cable attachment part 193 to generate the variable stroke speed of the mechanical piston 78. More specifically, in the second embodiment, the cable attachment part 193 includes a cable holder configured to retain the barrel-shaped nipple 21 cof the cable 21, and the contact surface 194 ais formed by a slot that slidably receives the cable holder (i.e., the cable attachment part 193). The cable holder has a cylindrical shape. The cable holder includes a container space configured to receive the barrel-shaped nipple 21 cand an attachment through hole configured to allow the inner wire 21 bof the cable 21 to pass therethrough. The cable attachment part 193 may include the barrel-shaped nipple 21 cof the cable 21, and the contact surface 194 amay be formed by a slot slidably receiving the barrel-shaped nipple 21 cof the cable 21. The contact surface 194 a(e.g., the slot) is aligned relative to the pivot axis A 4 of the intermediate member 181 so that the barrel shaped nipple 21 cof the cable 21 moves away from the pivot axis A 4 during a braking operation when the intermediate member 181 pivots about the pivot axis A 4. In this way, the cable attachment part 193 is configured to move at least partially away from the pivot axis A 4 when the intermediate member 181 pivots about the pivot axis A 4 during a braking operation. As a result, the mechanical piston 78 moves at a variable stroke speed relative to a stroke of the cable 21 when the intermediate member 181 pivots about the pivot axis A 4 during a braking operation. In this embodiment, the cam surface of the intermediate member 181 may have a constant inclination.Referring to FIGS. 33 and 34, a disc brake caliper 212 according to a third embodiment is illustrated.

For example, as in the third embodiment, the cable attachment part 293 is a cable holder, and the part 294 is a pivot pin for pivotally attaching the cable attachment part 293 (e.g., the cable holder) to the intermediate member 281. More specifically, in the third embodiment, the cable attachment part 293 is configured to fix the barrel-shaped nipple 21 cof the cable 21 to the intermediate member 281 via the part 294. During a braking operation, the cable attachment part 293 pivots relative to the intermediate member 281, so that the amount of angular rotation of the intermediate member 281 changes for a predetermined amount of the cable 21 pulled with respect to the caliper housing 73. More specifically, during a braking operation, the barrel-shaped nipple 21 cof the cable 21 moves away from the pivot axis A 4 as the intermediate member 281 rotates about the pivot axis A 4. In other words, the cable attachment part 293 is configured to move at least partially away from the pivot axis A 4 during a braking operation when the intermediate element 281 pivots about the pivot axis A 4. As a result, during a braking operation, the mechanical piston 78 moves at a variable stroke speed relative to a stroke of the cable 21 when the intermediate member 281 pivots about the pivot axis A 4.

The second brake pad 365B may be bonded to the second hydraulic piston 370 as needed and / or desired. Alternatively, the second brake pad 365B is held in contact with the second hydraulic piston 370 by the biasing member 367. In either case, the biasing member 367 applies a biasing force to the second brake pad 365B and the second hydraulic piston 370 such that the second brake pad 365B and the second hydraulic piston 370 do not contact the rotor 22 when the second brake lever 30 is in the unactuated position. The second cylinder 371 is in fluid communication with the hydraulic hose 20 via internal passages formed in the hydraulic caliper body 316.

Specifically, the first hydraulic piston 368 and the second hydraulic piston 370 are configured to move relative to the hydraulic caliper body 316 in response to actuation of the second brake lever 30. Thus, the first hydraulic piston 368 and the second hydraulic piston 370 are configured to move the first brake pad 365A and the second brake pad 365B to contact the disc brake rotor 22 from the rest position (i.e., the non-braking position) to the actuated position (i.e., the braking position) in response to actuation of the second brake lever 30. In other words, when the second brake lever 30 is operated by a user, the first hydraulic piston 368 and the second hydraulic piston 370 are moved relative to the hydraulic caliper body 316 to move the first brake pad 365A and the second brake pad 365B into contact with the disc brake rotor 22. Thus, in response to the operation of the second brake lever 30, the first brake pad 365A and the second brake pad 365B are in contact with the disc brake rotor 22 to apply a braking force to the disc brake rotor 22.Here, the hydraulic caliper body 316 is mainly constructed of two parts screwed and / or bonded together.

In the third embodiment, the cam portion 381 bis provided on the first shaft 381 c. In this case, the cable attachment portion 381 a, the cam portion 381 b, and the first shaft 381 care integrally formed as a one-piece member. Alternatively, the cable attachment portion 381 a, the cam portion 381 b, and the first shaft 381 cmay be separate members coupled to each other. A lower end of the first shaft 383 is rotatably supported in the caliper housing 373, while an upper end of the first shaft 381 cis rotatably supported in the lid 374. In this way, the intermediate member 381 is pivotally supported on the caliper mechanical body 318 via the first shaft 381 c. The pivot axis A 4 is different from the axis A 3 of the mechanical piston. Here, in the third embodiment, the pivot axis A 4 is not parallel to the axis A 3 of the mechanical piston.

In other words, the cable attachment part 593 is configured to move at least partially away from the pivot axis A 4 during a braking operation when the intermediate element 581 pivots about the pivot axis A 4. As a result, the mechanical piston 78 moves at a variable stroke speed relative to a stroke of the cable 21 when the intermediate member 581 pivots about the pivot axis A 4 during a braking operation.Referring to FIG. 60, there is shown a disc brake caliper 612 according to a seventh embodiment.
