Description

The present invention relates to a support structure, a brake system, and a saddle type vehicle.

Straddle-type vehicles (motorcycles) are generally equipped with a braking system that applies brakes to each of the front and rear wheels individually as a braking device to decelerate or stop the vehicle. ing. Furthermore, in recent years, front and rear linked braking systems (CBS) have been put into practical use, in which the brakes on both the front and rear wheels are operated in conjunction with each other by operating a lever on only one side.

Regarding the specific configuration of such a CBS, for example, there is a configuration in which the brake cable (brake cable holder that holds the brake cable) from the rear wheel brake is attached to the front wheel master cylinder from the front with a bolt (fastening member). It has been proposed (see Patent Document 1). In other words, the brake cable is attached to the master cylinder by bolting from the front.

The front fork 12 supports a bar handle 121 at its upper end, and supports a front wheel 123 via an axle 122 at its lower end.

The power unit 13 is supported by the vehicle body frame 11 and disposed between the front wheel 123 and the rear wheel 152. In this embodiment, the power unit 13 is configured as a drive source for an internal combustion engine, and includes, for example, an engine and a transmission that changes the output of the engine. Output (driving force) from the power unit 13 is transmitted to the rear wheels 152 via the drive shaft. Note that the power unit 13 may use a motor as a driving source.

The seat 14 is provided above the seat rail. The seats 14 include, for example, a seat where a driver is seated, a seat where a fellow passenger is seated, and the like. Further, the seat rail may be provided with a rear trunk or the like.

The swing arm 15 is supported by the center frame so as to be able to swing up and down, and supports a rear wheel 152 via an axle 151 at its rear end.

The brake device 16 includes a front wheel brake section 16A that brakes the front wheels 123, that is, functions as a brake for the front wheels 123, and a rear wheel brake section 16B that brakes the rear wheels 152, that is, functions as a brake for the rear wheels 152. including. The front wheel brake section 16A and the rear wheel brake section 16B include, for example, a disc brake, and are configured to be actuated by the driver's operation of a brake lever or brake pedal.

In this embodiment, the brake device 16 includes a brake lever 20, a master cylinder 30 including a knocker 31, and a brake hose provided for a front wheel brake section 16A that functions as a brake for the front wheel 123, as shown in FIG. 40 and a brake cable 50 provided for the rear wheel brake section 16B that functions as a brake for the rear wheel 152, as well as the brake cable 50 provided for the rear wheel brake section 16B that functions as a brake for the rear wheel 152. A front and rear interlocking brake system (hereinafter referred to as "brake system") BS is configured to operate the wheel brake parts 16B in conjunction with each other. Brake system BS is also called combination brake system (CBS). FIG. 2 is a schematic diagram showing an example of the basic configuration of the brake system BS. Note that since any technology well known in the art can be applied to the brake system BS, a detailed description thereof will be omitted here.

In addition, the straddle-type vehicle 1 is provided with a support structure for supporting the brake system BS in relation to the brake system BS. Hereinafter, the brake system BS, particularly the support structure for supporting the brake hose 40 and the brake cable 50, will be described in detail.

First, with reference to FIG. 3, as a comparative example of the present embodiment, a general support structure ( The support structure in the prior art will be explained. FIG. 3 is a diagram showing a typical support structure for supporting a brake system.

As shown in FIG. 3, in a typical support structure, the brake cable from the brake of the rear wheel 152 is attached from the front to the master cylinder of the brake of the front wheel 123. Specifically, the brake cable can be attached to the master cylinder by fastening the cable holder that holds the brake cable to the master cylinder from the front with bolts (bolting from the front to the rear). .

However, with the general support structure in which the brake cable (the cable holder that holds the master cylinder) is bolted from the front to the master cylinder, there is a high possibility that flying objects such as flying stones will come into contact with the bolt. It can be said that this is a support structure in which bolt buckling or damage is likely to occur due to contact with objects. If the bolt buckles or breaks, the brake cable may fall off from the master cylinder, or the bolt may become difficult to remove. Further, since the bolt for attaching the brake cable to the master cylinder is a support structure that is visible from the front, the design quality is impaired.

Therefore, in this embodiment, the straddle-type vehicle 1 is provided with a support structure SS as shown in FIG. 4 instead of a general support structure. The support structure SS is a support structure for supporting a brake system BS that interlocks and operates the brakes of the front wheels 123 and rear wheels 152 of the straddle-type vehicle 1, and is a support structure for attaching the brake cable 50 to the master cylinder 30. This provides a new technology regarding support structures. FIG. 4 is a diagram showing the support structure SS of this embodiment for supporting the brake system BS.

The master cylinder 30 is supported by the bar handle 121, and is arranged near the right brake lever 20, as shown in FIG. When the brake lever 20 is operated (squeezed) by the driver, the master cylinder 30 introduces brake hydraulic pressure to the brake of the front wheel 123 (front wheel brake section 16A) via the brake hose 40, and applies the brake of the front wheel 123. Activate. Further, the master cylinder 30 is provided with a knocker 31 for operating an equalizer connected to the brake cable 50 via the brake cable 50 and operating the brake of the rear wheel 152 (rear wheel brake section 16B). There is. Therefore, in this embodiment, both the front wheel 123 brake and the rear wheel 152 brake can be operated by simply operating the right brake lever 20 (brake system BS (CBS) is configured).

A support structure SS that supports such a brake system BS has a cable support section 100 that supports a brake cable 50 included in the brake system BS, as shown in FIG. 4. In this embodiment, the cable support section 100 is supported by the master cylinder 30 and is provided below the master cylinder 30. The cable support section 100 may be configured integrally with the master cylinder 30 or may be configured separately from the master cylinder 30 and attached to the master cylinder 30.

As shown in FIG. 5, the cable support section 100 includes a main body section 110 supported by the master cylinder 30, and a lower portion 120 formed continuously from the main body section 110. The lower portion 120 is located below the main body 110 in the vertical direction and has an outer diameter larger than the outer diameter of the main body 110. In other words, the lower portion 120 is formed below the main body portion 110 and has a larger diameter than the main body portion 110 . Further, as shown in FIG. 6, the lower part 120 is provided with a fixing part 124 on the lower surface 125 thereof to fix the brake cable 50. FIG. 5 is an enlarged view showing the vicinity of the master cylinder 30 and the cable support section 100. FIG. 6 is a view showing the master cylinder 30 and cable support section 100 shown in FIG. 5 from below. In addition, in FIG. 6, illustration of the brake cable 50 is omitted in order to show the structure of the lower surface 125 of the lower part 120 of the cable support part 100.

As shown in FIGS. 5 and 6, by providing the fixing part 124 on the lower surface 125 of the lower part 120 whose diameter is larger than that of the main body part 110, it is possible to attach the brake cable 50 to the master cylinder 30 from below. At the same time, the fixing surface for fixing the brake cable 50 can be made larger (wider). Therefore, it is possible to firmly attach the brake cable 50 to the cable support section 100 from below, thereby increasing the force supporting the brake cable 50 and suppressing the brake cable 50 from falling off from the cable support section 100. can do.

Note that in reality, instead of attaching the brake cable 50 to the master cylinder 30 as is, it is better to attach the brake cable 50 to the master cylinder 30 using a cable holder 510, as shown in FIGS. 4 and 5. Common. The cable holder 510 holds the brake cable 50 by surrounding the outer periphery of the end of the brake cable 50 on the master cylinder 30 side (the side opposite to the rear wheel brake section 16B side). Therefore, the fixing part 124 provided on the lower surface 125 of the lower part 120 of the cable support part 100 fixes the brake cable 50 via the cable holder 510. By using the cable holder 510, the brake cable 50 can be easily attached to the master cylinder 30, and damage or breakage of the brake cable 50 due to external impact can be suppressed.

Further, as shown in FIGS. 7 and 8, the support structure SS includes a fastening member 200 that fastens (combines) the cable holder 510 and the fixing part 124 provided on the lower surface 125 of the lower part 120 of the cable support part 100. It also has. Specifically, the fastening member 200 is made of a bolt, and is inserted from below the cable holder 510 through bolt holes formed in the cable holder 510 and the fixing part 124 from the lower surface of the lower part 120 where the fixing part 124 is provided. The cable holder 510 and the fixing part 124 are fastened together along the direction toward the cable holder 125 (vertical direction). In this way, by bolting the cable holder 510 to the master cylinder 30 from below using the bolt as the fastening member 200, the fastening member 200 (bolt) is attached to the lower surface 125 of the lower part 120 of the cable support section 100. It will be established in Therefore, in this embodiment, there is a low possibility that a flying object such as a flying stone coming from the front will come into contact with the fastening member 200 (bolt), and buckling or damage of the fastening member 200 is suppressed, and the brake is not applied to the master cylinder 30. It is possible to avoid the cable 50 (cable holder 510) falling off and the fastening member 200 becoming difficult to remove. Furthermore, since the fastening member 200 for attaching the brake cable 50 (cable holder 510) to the master cylinder 30 is difficult or invisible from the front, the design is excellent. FIG. 7 is a view showing from below a fastening member 200 that fastens the cable holder 510 and the fixing part 124 provided on the lower surface 125 of the lower part 120 of the cable support part 100, and FIG. It is a figure showing member 200 from the side.

In this embodiment, as shown in FIG. 9, the cable holder 510 includes a holder main body 512 having a function of holding the brake cable 50, and a fastening member 200 extending rearward from the holder main body 512. holder extension part 514 in which a bolt hole for passing a bolt (bolt) is formed. Furthermore, the fastening member 200 fastens the cable holder 510 and the fixing part 124 provided on the lower surface 125 of the lower part 120 of the cable support part 100 via the holder extension part 514 (the bolt hole formed in it). This allows the fastening member 200 to be placed behind the holder main body 512 (the brake cable 50 held therein), thereby reducing the possibility that flying objects such as flying stones coming from the front will come into contact with the fastening member 200. can be lowered. Therefore, buckling or damage of the fastening member 200 caused by flying objects is suppressed, and the brake cable 50 (cable holder 510) is prevented from falling off from the master cylinder 30 or it is difficult to remove the fastening member 200. In addition to avoiding this problem, the fastening member 200 can be structured to be difficult or invisible from the front, which is excellent in design. FIG. 9 is an enlarged view showing the vicinity of the master cylinder 30, cable support section 100, and cable holder 510.

Here, in order to arrange the fastening member 200 at the rear of the holder main body part 512, as shown in FIG. It is necessary to make the height higher than the height of the holder extension part 514 located behind the holder extension part 512. Specifically, the length L1 of the holder main body 512 in the height direction is made longer than the length L2 of the holder extension part 514 in the height direction, and the lower part of the holder main body 512 is made longer in the height direction. , the cable holder 510 is configured to be located at a lower position than the lower part of the holder extension part 514. As a result, the fastening member 200 is placed behind the holder main body 512, and the fastening member 200 (the seat surface of the bolt) can be hidden by the holder main body 512, especially when viewed from the front. It is possible to suppress buckling and damage of the fastening member 200 caused by flying objects from the front, and to achieve an excellent design.

As shown in FIGS. 10 and 11, a switch 300 is arranged below and outside the master cylinder 30. As shown in FIGS. The switch 300 is configured to operate the straddle-type vehicle 1 in response to the operation of the right brake lever 20 in order to indicate the operation of the front wheel 123 brake (front wheel brake section 16A) or the rear wheel 152 brake (rear wheel brake section 16B). This is a switch to turn on the brake light located at the rear of the vehicle. In this way, considering the switch 300 disposed below and on the outside of the master cylinder 30, the cable support section 100 is arranged below the master cylinder 30 and on the inside of the switch 300 (switch 300). Furthermore, as shown in FIGS. 10 and 11, the inner side surface 32 of the master cylinder 30 and the inner side surface 102 of the cable support part 100 (main body part 110) do not match in the width direction, and the cable support The inner side surface 102 of the section 100 is spaced inwardly from the inner side surface 32 of the master cylinder 30 by a predetermined distance D. In other words, the cable support portion 100 is configured to protrude inward from the inner side surface 32 of the master cylinder 30. Thereby, a space for arranging the switch 300 is secured below the master cylinder 30, and the switch 300 can be easily arranged. 10 and 11 are diagrams showing the positional relationship between the cable support section 100 and the switch 300 below the master cylinder 30.

Further, the switch 300 includes a connector 310 provided below the master cylinder 30 and on the side of the cable support section 100, as shown in FIGS. 12(a) and 12(b). In this embodiment, the connector 310 is composed of a plug (terminal) that protrudes toward the cable support section 100, as shown in FIG. 12(b). Therefore, below the master cylinder 30, not only a space for arranging the switch 300 but also a space for arranging the connector 310, a wiring to be attached to and removed from the connector 310, or a space for arranging the wiring holder 700 for holding such wiring is also required. Therefore, in this embodiment, a recessed portion 130 is provided in the cable support portion 100, as shown in FIG. 12(a), corresponding to the position where the connector 310 is provided. The recessed portion 130 has a recessed (concave) shape with respect to the direction in which the connector 310 is attached and detached, and is provided in the cable support portion 100 so that the connector 310 can be attached and detached. Note that the attachment and detachment of the connector 310 includes wiring to the connector 310 or attachment of the wiring holder 700, and wiring from the connector 310 or removal of the wiring holder 700. In FIG. 12A, the wiring holder 700 when attached to the connector 310 is shown as a wiring holder 700A, and the wiring holder 700 when removed from the connector 310 is shown as a wiring holder 700B. By providing such a recessed portion 130, a space for arranging the connector 310, a space for wiring to be attached and detached from the connector 310, or a space for arranging the wiring holder 700 can be secured, and the connector 310 can be easily attached and detached. can. Further, in this embodiment, as shown in FIG. 12(b), a convex portion 312 (protrusion) is formed on the connector 310. Since the wiring holder 700 is made of deformable resin, by fitting the convex part 312 formed on the connector 310 with the concave part formed on the wiring holder 700 corresponding to the convex part 312, Connector 310 can hold wiring holder 700 in a non-detachable manner. FIG. 12A is a diagram showing the positional relationship between the cable support section 100 and the connector 310 below the master cylinder 30. FIG. 12(b) is an enlarged perspective view of the connector 310 shown in FIG. 12(a). However, in FIG. 12(b), in order to show the structure of the connector 310, illustration of the wiring holder 700 that is attached to and detached from the connector 310 is omitted.

In addition, as shown in FIG. 12(a), on the lower surface 125 of the lower part 120 of the cable support section 100, in addition to a fixing section 124 that fixes the brake cable 50 (cable holder 510), It is preferable to provide a protrusion 126 that supports the support. For example, the protrusion 126 may support the brake cable 50 unrotatably by fitting into a fitting hole provided in the cable holder 510 (the holder extension 514 of the cable holder 510), or The brake cable 50 may be unrotatably supported by contacting the side surface. Thereby, the cable support section 100 can suppress unnecessary rotation of the brake cable 50, and as a result, the brake cable 50 can be firmly supported. In addition, on the lower surface 125 of the lower part 120 of the cable support part 100, the protrusions 126 are aligned in the width direction with respect to the fixing part 124 and are shifted in the front-rear direction, as shown in FIG. 12(a). By arranging it, it becomes possible to secure a space for arranging the connector 310 and to provide a recessed portion 130 that facilitates the attachment and detachment of the connector 310.

Moreover, the support structure SS may have a hose support part 600 that supports the brake hose 40 connected to the master cylinder 30, as shown in FIG. In this embodiment, the hose support section 600 has a function of unrotatably supporting the brake hose 40, and includes a first support member 610 and a second support member 620. The first support member 610 and the second support member 620 are provided at different positions in the height direction and sandwich the brake hose 40. In other words, the first support member 610 and the second support member are provided with an interval corresponding to the outer diameter of the brake hose 40 in the height direction. Thereby, the hose support portion 600 can suppress unnecessary rotation of the brake hose 40, and as a result, the brake hose 40 can be firmly supported.

In this embodiment, as shown in FIG. 13, the first support member 610 is provided extending from the master cylinder 30 so as to be located above the second support member 620 in the height direction. . The second support member 620 is provided extending from the cable support section 100 so as to be located below the first support member 610 in the height direction. Further, as shown in FIG. 4, the length L4 of the portion (extending portion) of the second support member 620 extending from the cable support portion 100 is longer than the length L4 of the first support member extending from the master cylinder 30. The first support member 610 and the second support member 620 are configured to be shorter than the length L3 of the portion 610 (extended portion). Since the load on the brake hose 40 is likely to be applied from above or from the front, the load applied to the second support member 620 is basically larger than the load applied to the first support member 610. However, in this embodiment, as described above, by making the length of the second support member 620 (the extended portion thereof) shorter than the length of the first support member 610 (the extended portion thereof), the second support member 620 is The rigidity of the member 620 is increased. Therefore, even if a large load is applied to the second support member 620, deformation or damage of the second support member 620 is suppressed, so that the hose support portion 600 can firmly support the brake hose 40. FIG. 13 is an enlarged view showing the vicinity of the master cylinder 30 and the hose support section 600. In FIG. 13, illustration of the brake hose 40 is omitted in order to show the structure of the hose support section 600.

In addition, in this embodiment, the rigidity of the second support member 620 is increased by shortening the length of the second support member 620, but the rigidity of the second support member 620 is increased. As long as it can be improved, the method does not matter. For example, the second support member 620 may be made of a highly rigid material, or the thickness (length in the height direction) of the second support member 620 may be increased.

As described above, according to the present embodiment, it is possible to provide a new technique regarding a support structure that supports the brake system BS, for example, a support structure for attaching the brake cable 50 to the master cylinder 30. Specifically, it is possible to suppress buckling and damage of the fastening member 200 (bolt) for attaching the brake cable 50 to the master cylinder 30, and to realize a support structure SS having an excellent design. can.
