Description
[Technical field]
[0001] The present invention relates to lean vehicles. [Background technology]
[0002] There is known a standing type lean vehicle in which the driver places his / her left foot on the left foot step and his / her right foot on the right foot step. For example, Non-Patent Document 1 discloses an example of such a lean vehicle, which is a two-wheeled vehicle in which a license plate, a tail lamp, and a turn signal are provided in the center of the rear of the vehicle.
[0003] In the two-wheeled vehicle of Non-Patent Document 1, the left foot step portion and the right foot step portion are each located between the front wheel and the rear wheel in the front-rear direction of the vehicle and are fixed to the body frame.
[0004] In addition, in the two-wheeled vehicle of Non-Patent Document 1, the license plate, tail lamps, and turn signals are attached to a frame that extends upward from the rear frame, so that the license plate, tail lamps, and turn signals are located above the rear wheel axle.
[0005] Patent Document 1 discloses a vehicle including a body frame, a left front wheel and a right front wheel, and a link mechanism located above the left front wheel and the right front wheel and configured to change the relative positions of the left front wheel and the right front wheel with respect to the body frame to tilt the body frame to the left or right of the vehicle. The link mechanism includes an upper cross member and a lower cross member extending in the left-right direction, a right side member that rotatably supports right ends of the upper cross member and the lower cross member, and a left side member that rotatably supports left ends of the upper cross member and the lower cross member. Intermediate portions of the upper cross member and the lower cross member are supported by the body frame in front of the steering shaft.
[0006] The upper cross member and the lower cross member are supported by the body frame so as to be rotatable about an axis extending substantially in the front-rear direction of the body frame. The upper cross member and the lower cross member rotate relative to the body frame in conjunction with the inclination of the body frame, changing the relative positions of the two front wheels in the vertical direction of the body frame.

[0008] [Patent Document 1] International Publication No. 2018 / 216727 [Non-patent literature]
[0009] [Non-Patent Document 1] "glafit [Press Release]", Glafit Co., Ltd., [Retrieved June 12, 2020], Internet (https: / / glafit.com / news / pr20200528) Summary of the Invention [Problem to be solved by the invention]
[0010] Incidentally, in the vehicle disclosed in Patent Document 1, the driver starts driving the vehicle with his / her left foot placed on the left foot rest (left foot step portion) and his / her right foot placed on the right foot rest (right foot step portion).
[0011] Therefore, in a vehicle having a left front wheel and a right front wheel, there is a need for a configuration that allows the left foot to be easily placed on the left foot step portion and the right foot to be easily placed on the right foot step portion.
[0012] An object of the present invention is to provide a configuration in a lean vehicle having a left front wheel and a right front wheel that allows a left foot to be easily placed on a left foot step portion and a right foot to be easily placed on a right foot step portion. [Means for solving the problem]
[0013] The present inventors have investigated a configuration for a lean vehicle having a left front wheel and a right front wheel that allows the left foot to be easily placed on the left foot step portion and the right foot to be easily placed on the right foot step portion.
[0014] As a result of extensive investigation, the present inventors have come up with the following configuration.
[0015] A lean vehicle according to one embodiment of the present invention comprises a body frame, a left front wheel located to the left of the body frame in the left-right direction of the body frame, a right front wheel located to the right of the body frame in the left-right direction of the body frame, a rear wheel located between the left front wheel and the right front wheel when viewed in the front-to-rear direction of the body frame and located behind the left front wheel and the right front wheel in the front-to-rear direction of the body frame, a link mechanism supported by the front of the body frame and allowing left and right leaning in the left-to-right direction of the body frame, a left foot step portion having a left foot rest surface on which a driver's left foot is placed and at least a portion of which is located behind the left front wheel, and a right foot step portion having a right foot rest surface on which the driver's right foot is placed and at least a portion of which is located behind the right front wheel, and is a lean vehicle that leans to the left when turning left and leans to the right when turning right. This lean vehicle further includes rear equipment that is supported on a rear portion of the vehicle body frame and does not include a rear fender that covers at least a portion of an upper portion of the rear wheel. The rear equipment is positioned such that the front-rear distance between the rear end of the left foot step portion and the front end of the rear equipment is greater than half the front-rear length of the left foot step portion, and the front-rear distance between the rear end of the right foot step portion and the front end of the rear equipment is greater than half the front-rear length of the right foot step portion. The rear equipment is positioned such that the vertical height of the upper end of the rear equipment relative to the left foot rest surface of the left foot step portion is lower than the vertical height of the left foot rest surface of the left foot step portion relative to the ground, and the vertical height of the upper end of the rear equipment relative to the right foot rest surface of the right foot step portion is lower than the vertical height of the right foot rest surface of the right foot step portion relative to the ground. The rear equipment is located between the left and right centers of the left and right foot step portions when the lean vehicle is viewed from behind.
[0016] When a driver gets into the lean vehicle described above, the driver gets into the lean vehicle from behind. When the driver gets into the lean vehicle from behind, the driver needs to position the driver's feet on the left and right of the rear wheels of the lean vehicle. Therefore, it is necessary to secure a space in which the driver can position the driver's feet on the left and right of the rear wheels of the lean vehicle.
[0017] In contrast, in the above-mentioned configuration, the rear equipment is located at a position separated in the front-rear direction from the left foot step portion and the right foot step portion, and is located between the left and right centers of the left and right foot step portions when viewing the lean-back vehicle from behind, thereby making it possible to secure space for the driver to position their feet on the left and right of the rear wheels.
[0018] Moreover, the vertical height of the upper end of the rear equipment relative to the left foot rest surface of the left foot step portion is lower than the vertical height of the left foot rest surface of the left foot step portion relative to the ground, and the vertical height of the upper end of the rear equipment relative to the right foot rest surface of the right foot step portion is lower than the vertical height of the right foot rest surface of the right foot step portion relative to the ground. This makes it possible to prevent the rear equipment from getting in the way when the driver gets into the lean vehicle.
[0019] Therefore, in a lean vehicle having a left front wheel and a right front wheel, a configuration can be obtained in which the left foot can be easily placed on the left foot step portion and the right foot can be easily placed on the right foot step portion.
[0020] The rear equipment refers to parts provided at the rear of a lean-to vehicle, such as a license plate support bracket for supporting a license plate, a reflector, and a lighting device.
[0021] From another viewpoint, it is preferable that the lean vehicle includes the following configuration: The lean vehicle further includes a rear member support portion that supports at least one of the rear fender and the rear equipment relative to the body frame.
[0022] This allows at least one of the rear fender and the rear equipment to be supported by the vehicle body frame, thus easily realizing a configuration in which the rear fender and the rear equipment are disposed at the rear of a lean-to vehicle.
[0023] In another aspect, the lean vehicle preferably includes the following configuration: an upper end of the rear equipment is lower than an upper end of the rear fender.
[0024] This makes it possible to prevent the driver's feet from coming into contact with the rear equipment and being obstructed by the rear equipment when the driver gets into the lean vehicle.
[0025] According to another aspect, the lean vehicle preferably includes the following configuration: The rear equipment includes at least one of a license plate support bracket for supporting a license plate, a reflector, and a lighting device.
[0026] This makes it possible to obtain a configuration in which, in a lean vehicle having a license plate support bracket for supporting a license plate at the rear of the vehicle, a reflector, and turn signals, the left foot can be easily placed on the left foot step portion and the right foot can be easily placed on the right foot step portion.
[0027] From another viewpoint, it is preferable that the lean vehicle includes the following configuration. The lean vehicle further includes a tilt suppression mechanism capable of changing between an operating state and a non-operating state so that in an operating state, the tilt suppression mechanism suppresses left and right tilt of the link mechanism, and in a non-operating state, the tilt suppression mechanism does not suppress left and right tilt of the link mechanism. This allows the driver to get into the lean vehicle in the operating state of the tilt suppression mechanism, i.e., in a state in which the tilt of the link mechanism is suppressed by the tilt suppression mechanism. This allows the driver to easily get into the lean vehicle.

[0048] Hereinafter, the embodiments will be described with reference to the drawings. In each drawing, the same parts are given the same reference numerals, and the description of the same parts will not be repeated. Note that the dimensions of the components in each drawing do not faithfully represent the actual dimensions of the components and the dimensional ratios of each component.
[0049] Hereinafter, arrow F in the figure indicates the forward direction of the lean vehicle 1. Arrow B in the figure indicates the rearward direction of the lean vehicle 1. Arrow U in the figure indicates the upward direction of the lean vehicle 1. Arrow D in the figure indicates the downward direction of the lean vehicle 1.

In addition, the front-rear direction, left-right direction, and up-down direction of the body frame respectively refer to the front-rear direction, left-right direction, and up-down direction based on the body frame when viewed from the perspective of a passenger driving the lean vehicle.
[0051] (Overall composition) FIG. 1 is a left side view showing an outline of the overall configuration of a lean vehicle 1 according to an embodiment. FIG. 2 is a left side view showing the lean vehicle 1 with a main frame cover 25 removed. The lean vehicle 1 includes a vehicle body 2, a pair of left and right front wheels 3, a rear wheel 4, a link mechanism 5, a steering mechanism 6, a tilt suppression mechanism 7, and a load transmission mechanism 8. That is, the lean vehicle 1 in this embodiment is a three-wheeled vehicle having a pair of left and right front wheels 3. The lean vehicle 1 is a vehicle that leans to the left when turning left and leans to the right when turning right.
[0052] The lean vehicle 1 is not provided with a seat on which the driver sits. In other words, the lean vehicle 1 is a so-called standing vehicle in which the driver rides while standing. The lean vehicle 1 is also not provided with a rear arm that supports the rear wheels 4. The rear wheels 4 of the lean vehicle 1 are supported by a body frame 21 described below. The lean vehicle 1 is also not provided with a shock absorber that elastically supports the front wheels 3 and rear wheels 4 so that they can be displaced. The front wheels 3 and rear wheels 4 of the lean vehicle 1 are supported by the body frame 21 described below without the intervention of a shock absorber.
[0053] The vehicle body 2 includes a body frame 21 and a power unit 22. In Fig. 1 and Fig. 2, the body frame 21 is in an upright state. In the following description, when referring to Fig. 1 or Fig. 2, it is assumed that the body frame 21 is in an upright state. Note that the upright state of the body frame 21 means a state in which the up-down direction of the body frame 21 is the same as the vertical direction.
[0054] 2, the body frame 21 supports a power unit 22 and the like. The body frame 21 includes a head pipe 211 and a main frame 212.
[0055] The head pipe 211 is located at the front of the lean vehicle 1. When the lean vehicle 1 is viewed from the left, an upper part of the head pipe 211 is located behind a lower part of the head pipe 211 in the front-rear direction of the body frame 21. A link mechanism 5 is disposed around the head pipe 211. A steering shaft 652, which will be described later, is rotatably inserted into the head pipe 211.
[0056] The main frame 212 is connected to the head pipe 211. The main frame 212 is located behind the head pipe 211 in the front-rear direction of the body frame 21. The main frame 212 supports the power unit 22. A rear end portion of the main frame 212 supports the rear wheel 4 rotatably about the wheel axle 41. As shown in FIG. 1, the main frame 212 is covered by a main frame cover 25. The main frame cover 25 is supported by the main frame 212. The main frame cover 25 is a resin member.
[0057] As shown in FIG. 2, the main frame 212 includes an upper frame 213 and an under frame 214 .
[0058] When the body frame 21 is viewed from the left, the upper frame 213 extends from the head pipe 211 toward the rear wheel 4, rearward in the front-rear direction of the body frame 21 and downward in the up-down direction of the body frame 21. The rear end of the upper frame 213 is branched into two so as to be located on the left and right of the rear wheel 4, respectively. That is, the upper frame 213 has an upper frame left rear end 213a located to the left of the rear wheel 4 and an upper frame right rear end 213b located to the right of the rear wheel 4. The upper frame left rear end 213a and the upper frame right rear end 213b support the rear wheel 4 together with an underframe left rear end 214c and an underframe right rear end 214d described below. The power unit 22 is supported by the upper frame 213.
[0059] The underframe 214 has an underframe front portion 214a and an underframe rear portion 214b. When viewed from the left of the body frame 21, the underframe front portion 214a extends from the head pipe 211 rearward in the front-to-rear direction of the body frame 21 and downward in the up-down direction of the body frame 21. A front end portion of the underframe front portion 214a is connected to the head pipe 211.
[0060] The underframe rear portion 214b extends rearward from the rear end portion of the underframe front portion 214a in the front-rear direction of the body frame 21. The rear end portion of the underframe rear portion 214b branches into two portions located on the left and right of the rear wheels 4. In other words, the underframe rear portion 214b has an underframe left rear end portion 214c located to the left of the rear wheel 4 and an underframe right rear end portion 214d located to the right of the rear wheel 4.
[0061] The underframe left rear end portion 214c is connected to the upper frame left rear end portion 213a. The underframe left rear end portion 214c and the upper frame left rear end portion 213a are connected in this manner to form the main frame left rear end portion 212a. The underframe right rear end portion 214d is connected to the upper frame right rear end portion 213b. The underframe right rear end portion 214d and the upper frame right rear end portion 213b are connected in this manner to form the main frame right rear end portion 212b. The main frame left rear end portion 212a and the main frame right rear end portion 212b support the rear wheel 4.
[0062] In this way, the main frame 212 has the upper frame 213 and the underframe 214, thereby making it possible to improve the strength and rigidity of the main frame 212. Note that, when the height of the main frame in the vertical direction of the body frame is to be reduced, the main frame may have only the underframe.
[0063] Fig. 3 is a front view of the front part of the lean vehicle 1. In Fig. 3, the body frame 21 is in an upright state. In the following description, when referring to Fig. 3, it is assumed that the body frame 21 is in an upright state.
[0064] 1 to 3, the pair of left and right front wheels 3 are located below the head pipe 211 and the link mechanism 5 in the vertical direction of the body frame 21. As shown in Fig. 2, the pair of left and right front wheels 3 are supported by a left suspension portion 61 and a right suspension portion 62, which will be described later.
[0065] As shown in Figures 1 and 2, the rear wheel 4 is located between the left front wheel 31 and the right front wheel 32 when looking at the body frame 21 in the fore-and-aft direction, and is located behind the left front wheel 31 and the right front wheel 32 in the fore-and-aft direction of the body frame 21.
[0066] The power unit 22 generates a driving force for running the lean vehicle 1. As shown in FIG. 2, the power unit 22 is located in front of the wheel axle 41 of the rear wheel 4 in the front-rear direction of the body frame 21. The power unit 22 is fixed to the body frame 21. The power unit 22 includes a motor and a battery 221 (not shown). In this embodiment, the motor is disposed inside the wheel 4a of the rear wheel 4. The motor is supplied with electric power from the battery 221 (not shown) fixed to the upper frame 213 of the body frame 21.
[0067] 3, the pair of left and right front wheels 3 include a left front wheel 31 and a right front wheel 32. The left front wheel 31 is located to the left of a head pipe 211, which is a part of the body frame 21, in the left-right direction of the body frame 21. The right front wheel 32 is located to the right of the head pipe 211 in the left-right direction of the body frame 21. In other words, the left front wheel 31 and the right front wheel 32 are located side by side in the left-right direction of the body frame 21.
[0068] 3, the left front wheel 31 is connected to the left suspension part 61. More specifically, the left front wheel 31 is connected to a lower part of the left suspension part 61. The left front wheel 31 is supported by the left suspension part 61 so as to be rotatable about a left axle 311. The left axle 311 is disposed below the left suspension part 61 so as to extend in the left-right direction of the body frame 21.
[0069] The right front wheel 32 is connected to the right suspension part 62. More specifically, the right front wheel 32 is connected to a lower part of the right suspension part 62. The right front wheel 32 is supported by the right suspension part 62 so as to be rotatable about a right axle 321. The right axle 321 is disposed below the right suspension part 62 so as to extend in the left-right direction of the body frame 21.
[0070] The link mechanism 5 is a four-parallel link (also called a parallelogram link) type link mechanism.
[0071] 1 to 3, the link mechanism 5 is located below the handlebar 651 in the vertical direction of the body frame 21. The link mechanism 5 is located above the left front wheel 31 and the right front wheel 32 in the vertical direction of the body frame 21.
[0072] As shown in FIGS. 1 to 3, the link mechanism 5 includes an upper cross portion 51, a lower cross portion 52, a left side portion 53, and a right side portion 54. The link mechanism 5 is not interlocked with the rotation of the steering shaft 652 about the intermediate steering axis Z associated with the operation of the handlebar 651. That is, the link mechanism 5 does not rotate about the intermediate steering axis Z relative to the body frame 21. The configuration of the link mechanism 5 is similar to the configuration disclosed in International Publication WO2020 / 111254. Therefore, a detailed description of the link mechanism 5 will be omitted.
[0073] The portion located on the left side of the link mechanism 5 is the left portion. For example, the left portion includes the left side portion 53. The portion located on the right side of the link mechanism 5 is the right portion. For example, the right portion includes the right side portion 54.
[0074] Similar to the link mechanism disclosed in International Publication No. 2020 / 111254, in the link mechanism 5 of this embodiment, the upper cross portion 51, the lower cross portion 52, the left side portion 53 and the right side portion 54 are supported by the body frame 21 so that the upper cross portion 51 and the lower cross portion 52 maintain a parallel posture to each other, and the left side portion 53 and the right side portion 54 maintain a parallel posture to each other.
[0075] As shown in FIG. 3, the steering mechanism 6 includes a left suspension portion 61, a right suspension portion 62, a left bracket 63, a right bracket 64, a steering member 65, and a steering force transmission mechanism 66. The configuration of the steering mechanism 6 is similar to that of the steering mechanism disclosed in WO 2020 / 111254. Therefore, a detailed description of the configuration of the steering mechanism 6 is omitted. Therefore, the steering operation of the lean vehicle 1 using the steering mechanism 6 is also similar to the steering operation disclosed in WO 2020 / 111254, and therefore a detailed description is omitted.
[0076] The left suspension part 61 supports the left front wheel 31 with respect to the link mechanism 5. The left suspension part 61 extends in the direction in which the intermediate steering axis Z extends. A lower end part of the left suspension part 61 supports the left front wheel 31. An upper end part of the left suspension part 61 is fixed to a left bracket 63.
[0077] The right suspension part 62 supports the right front wheel 32 with respect to the link mechanism 5. The right suspension part 62 extends in the direction in which the intermediate steering axis Z extends. A lower end part of the right suspension part 62 supports the right front wheel 32. An upper end part of the right suspension part 62 is fixed to a right bracket 64.
[0078] The steering member 65 includes a handle bar 651 and a steering shaft 652 .
[0079] The handlebar 651 is connected to an upper portion of the steering shaft 652. A portion of the steering shaft 652 is rotatably supported by the head pipe 211. The steering shaft 652 rotates about the intermediate steering axis Z in response to operation of the handlebar 651 by the rider.
[0080] The operation of the lean vehicle 1 tilting to the left or right is similar to the tilting operation disclosed in the above-mentioned International Publication No. 2020 / 111254. Therefore, a detailed description of the operation of the lean vehicle 1 tilting to the left or right will be omitted.
[0081] Fig. 4 is a top view of the lean vehicle 1 as viewed from above in the vertical direction of the body frame 21. In Fig. 4, the body frame 21 is in an upright state. In the following description, when Fig. 4 is referred to, it is assumed that the body frame 21 is in an upright state. Note that Fig. 10 also shows the same view as Fig. 4.
[0082] As shown in FIGS. 4 and 5, the load transfer mechanism 8 has a left foot load transfer part 81, a right foot load transfer part 82, and left and right connecting members 83.
[0083] The left foot load transfer portion 81 has a left foot placement portion 811 (left foot step portion) and a left connecting portion 812. At least a portion of the left foot placement portion 811 is located behind the left front wheel 31.
[0084] The left foot rest 811 has a left foot rest surface 811a on which the left foot of a standing driver is placed. The left connecting portion 812 connects the left foot rest 811 to the left side portion 53 of the link mechanism 5. As shown in FIG. 1, the left connecting portion 812 extends from the left side portion 53 rearward in the front-rear direction of the body frame 21 and downward in the up-down direction of the body frame 21. The rear end of the left connecting portion 812 is connected to the left foot rest 811. The left foot load transfer portion 81 is configured to be able to transfer the load of the driver input via the left foot rest 811 to the left side portion 53. The left connecting portion may be integral with the left side portion.
[0085] 4 and 5, the right foot load transmission portion 82 has a right foot placement portion 821 (right foot step portion) and a right connecting portion 822. At least a portion of the right foot placement portion 821 is located behind the right front wheel 32.
[0086] The right foot rest 821 has a right foot rest surface 821a on which the right foot of a standing driver is placed. The right connecting part 822 connects the right foot rest 821 to the right side part 54 of the link mechanism 5. The right connecting part 822 extends from the right side part 54 rearward in the front-rear direction of the body frame 21 and downward in the up-down direction of the body frame 21. The rear end part of the right connecting part 822 is connected to the right foot rest 821. The right foot load transmission part 82 is configured to be able to transmit the load of the driver inputted through the right foot rest 821 to the right side part 54. The right connecting part may be integral with the right side part.
[0087] With the above-described configuration, the inclination of the body frame 21 can be controlled by individually adjusting the load applied to the left foot rest 811 via the driver's left foot and the load applied to the right foot rest 821 via the driver's right foot.
[0088] For example, as shown in Figures 6 and 7, when the body frame 21 of the lean vehicle 1 leans to the left, the left side portion 53 is positioned higher than the right side portion 54 in the vertical direction of the body frame 21. Figure 6 is a front view of the lean vehicle 1 with the body frame 21 leaning to the left, as viewed from the front of the body frame 21. Figure 7 is a rear view of the lean vehicle 1 with the body frame 21 leaning to the left, as viewed from behind the body frame 21.
[0089] When a load is applied to the left side portion 53 by the left foot through the left foot rest portion 811, a force that displaces the body frame 21 downward acts on the left side portion 53. This makes it possible to suppress the body frame 21 from tilting to the left in the left-right direction of the lean-type vehicle 1.
[0090] Conversely, when the body frame 21 leans to the right of the lean vehicle 1, the right side portion 54 is positioned higher than the left side portion 53 in the vertical direction of the body frame 21. When a load is applied to the right side portion 54 with the right foot through the right foot placement portion 821, a force acts on the right side portion 54 to displace the body frame 21 downward. This makes it possible to suppress the body frame 21 from leaning to the right in the left-right direction of the lean vehicle 1.
[0091] When the body frame 21 tilts left or right from the upright state, the normal direction of the left foot rest 811 to the rest surface and the normal direction of the right foot rest 821 to the rest surface change. However, the angle formed by the direction in which the head pipe 211 extends (the direction in which the middle steering axis Z extends) and the rest surface of the left foot rest 811 and the rest surface of the right foot rest 821 does not change. In other words, the normal direction of the left foot rest 811 to the rest surface and the normal direction of the right foot rest 821 to the rest surface are always the same as the up-down direction of the body frame 21.
[0092] The left and right connecting members 83 connect the left and right foot rests 811 and 821 in the left-right direction of the body frame 21 below the body frame 21. In the left-right direction of the body frame 21, a central portion of the left and right connecting members 83 is supported by a rotation support portion (not shown) fixed to a lower portion of the underframe 214 of the body frame 21 so as to be rotatable about the underframe 214. Therefore, the left and right connecting members 83 tilt in the up-down direction in response to the up-down movement of the left and right foot rests 811 and 821 in the up-down direction of the body frame 21.
[0093] As a result, the left foot rest 811 and the right foot rest 821 move up and down in conjunction with each other in response to the load input of the left foot to the left foot rest 811 or the load input of the right foot to the right foot rest 821. Therefore, the left or right tilt of the body frame 21 can be easily suppressed by the load input of the left foot to the left foot rest 811 or the load input of the right foot to the right foot rest 821 as described above.
[0094] The tilt suppression mechanism 7 suppresses left and right tilt of the link mechanism 5. The tilt suppression mechanism 7 has a tilt suppression operator 71, a tilt suppression brake disc 72, and a caliper (not shown). The tilt suppression operator 71 is a lever-shaped member attached to the steering shaft 652. The tilt suppression brake disc 72 is a U-shaped plate-shaped member fixed to the left and right connecting members 83. The caliper is fixed to the underframe 214 of the main frame 212. The caliper is configured to be able to clamp the tilt suppression brake disc 72 in the thickness direction.
[0095] By rotating the tilt suppression operating member 71, the tilt suppression mechanism 7 is switched between an activated state and a deactivated state. When the tilt suppression mechanism 7 is activated, the caliper is driven to clamp the tilt suppression brake disc 72 in its thickness direction. This suppresses the swing of the left and right connecting members 83 of the load transfer mechanism 8 relative to the underframe 214 of the main frame 212. As described above, the left connecting portion 812 of the load transfer mechanism 8 is connected to the left side portion 53 of the link mechanism 5, and the right connecting portion 822 of the load transfer mechanism 8 is connected to the right side portion 54 of the link mechanism 5. Therefore, by operating the tilt suppression operating member 71 of the tilt suppression mechanism 7 to activate the tilt suppression mechanism 7 as described above, the left and right tilts of the link mechanism 5 relative to the main frame 212 can be suppressed.
[0096] Since the lean vehicle 1 has the above-mentioned tilt suppression mechanism 7, when the driver gets on the lean vehicle 1, the left and right tilts of the link mechanism 5 can be suppressed by the tilt suppression mechanism 7. Therefore, the driver can easily place his / her left foot on the left foot placement portion 811 of the lean vehicle 1 and can easily place his / her right foot on the right foot placement portion 821.
[0097] 1 to 3, 6 and 8, the lean-to vehicle 1 has a left front fender 33 and a right front fender 34. The left front fender 33 is located above the left front wheel 31 in the vertical direction of the body frame 21. By disposing the left front fender 33 above the left front wheel 31, the left front fender 33 can prevent water splashed up by the left front wheel 31 when the lean-to vehicle 1 is traveling from splashing on the left foot of the driver.
[0098] 3 and 8, the right front fender 34 is located above the right front wheel 32 in the up-down direction of the body frame 21. By disposing the right front fender 34 above the right front wheel 32, the right front fender 34 can prevent water splashed up by the right front wheel 32 when the lean-to vehicle 1 is traveling from splashing on the left foot of the driver.
[0099] As shown in Figures 1, 5, and 7 to 9, the lean vehicle 1 has a left foot guard 84 and a right foot guard 85. The left foot guard 84 is a resin plate member having a triangular shape in a plan view. The left foot guard 84 is fixed to the right end of the left foot rest 811 and to the left connecting part 812. The right foot guard 85 is a resin plate member having a triangular shape in a plan view. The right foot guard 85 is fixed to the left end of the right foot rest 821 and to the right connecting part 822.
[0100] As shown in Figs. 5, 8 and 9, the lean vehicle 1 has a left front guard 86 and a right front guard 87. The left front guard 86 is a resin plate member having a rectangular shape in a plan view. The left front guard 86 is fixed to the left connecting part 812 so that the longitudinal direction is along the extension direction of the left connecting part 812. The right front guard 87 is a resin plate member having a rectangular shape in a plan view. The right front guard 87 is fixed to the right connecting part 822 so that the longitudinal direction is along the extension direction of the right connecting part 822.
[0101] (Rear fender) 1, 2, 4, 5, 8 and 9, the lean vehicle 1 has a rear fender 42. The rear fender 42 is located above the rear wheel 4 in the up-down direction of the body frame 21. The rear fender 42 extends from the main frame 212 rearward in the fore-and-aft direction of the body frame 21 and upward in the up-and-down direction of the body frame 21. The rear fender 42 is a member made of resin.
[0102] The front and rear parts of the rear fender 42 are each supported by the main frame 212. Specifically, the front part of the rear fender 42 is fixed to a main frame cover 25 attached to the main frame 212 by a fastening member such as a bolt. The rear part of the rear fender 42 is fixed to a rear fender left support part 43 attached to the main frame left rear end part 212a and a rear fender right support part 44 attached to the main frame right rear end part 212b.
[0103] The rear fender left support portion 43 and the rear fender right support portion 44 have higher support rigidity than the portion of the rear fender 42 that is fixed to the main frame cover 25 attached to the main frame 212.
[0104] It should be noted that the rear fender left support portion 43 and the rear fender right support portion 44 correspond to the rear member support portion 40 that supports the rear fender 42 relative to the body frame 21 and also correspond to the rear fender rear support portion 42b. Of the rear fender 42, the portion that is fixed to the main frame cover 25 attached to the main frame 212 corresponds to the rear fender front support portion 42a.
[0105] The rear fender left support part 43 and the rear fender right support part 44 are each a metal plate-shaped member and extend in the radial direction of the rear wheel 4. The rear fender left support part 43 and the rear fender right support part 44 extend in the up-down direction. The rear fender left support part 43 is connected to the main frame left rear end part 212a and the rear fender 42 on the left of the rear wheel 4. That is, the lower end part of the rear fender left support part 43 is connected to the main frame left rear end part 212a. The upper end part of the rear fender left support part 43 is connected to the left part of the rear fender 42. The rear fender right support part 44 is connected to the main frame right rear end part 212b on the right of the rear wheel 4. That is, the lower end part of the rear fender right support part 44 is connected to the main frame right rear end part 212b. The upper end part of the rear fender right support part 44 is connected to the right part of the rear fender 42.
[0106] A pair of rear equipment support parts 45 that support rear equipment 100 described below are connected to the rear fender 42. The pair of rear equipment support parts 45 are metal plate-shaped parts extending in the front-rear direction. Front parts of the pair of rear equipment support parts 45 are connected to a connection part between the rear fender 42 and the rear fender left support part 43 and a connection part between the rear fender 42 and the rear fender right support part 44. In other words, the pair of rear equipment support parts 45 are connected to upper ends of the rear fender left support part 43 and the rear fender right support part 44. This allows the pair of rear equipment support parts 45 to be supported with high rigidity by the rear fender left support part 43 and the rear fender right support part 44. The pair of rear equipment support parts may be integral.
[0107] As will be described later, a rear equipment 100 is fixed to the rear of the pair of rear equipment supports 45 by fasteners such as bolts.
[0108] (Rear equipment) The lean-to vehicle 1 has a rear equipment 100 that is supported by the rear end of the vehicle body frame 21 and does not include a rear fender 42. The rear equipment 100 is supported on the main frame 212 by a rear fender left support portion 43 and a rear fender right support portion 44. The rear equipment 100 includes, for example, a license plate support bracket 102, a reflector 101, and a lighting device 103.
[0109] The rear equipment 100 may include at least one of the license plate support bracket 102, the reflector 101, and the lighting device 103, or may include other components disposed at the rear of the lean-to vehicle 1. The rear equipment 100 may include multiple components or may include only one component.
[0110] The reflecting unit 101 includes a reflector that reflects light incident from behind the lean-in vehicle 1, and a side reflector that reflects light incident from the left or right of the lean-in vehicle 1. In this embodiment, the reflecting unit 101 is supported by a pair of rear equipment supports 45 above the rotation center of the rear wheels 4. The reflecting unit 101 is a flat plate member with a reflective material on its surface. The reflecting unit 101 is attached to the pair of rear equipment supports 45 so that the surface with the reflective material is located at the rear.
[0111] The license plate support bracket 102 is, for example, a plate-like or frame-like member that supports a license plate. In this embodiment, the license plate support bracket 102 is located above the wheel axle 41 of the rear wheel 4, and is supported by a pair of rear equipment supports 45. In this embodiment, the reflector 101 is located above the license plate support bracket 102.
[0112] The lighting device 103 is an equipment capable of emitting light such as a turn signal, a tail light, a stop light, a license plate light, etc. The lighting device 103 may include a laser imaging device that projects an image on the road surface located behind the leaning vehicle 1.
[0113] In this embodiment, the lighting equipment 103 is located on the left and right of the reflecting part 101. The lighting equipment 103 may be located above the reflecting part 101 in the up-down direction, or may be located below the reflecting part 101. The lighting equipment 103 is also located above the wheel axle 41 of the rear wheel 4, and is supported by a pair of rear accessory supports 45.
[0114] The reflecting portion 101 may be supported by the pair of rear equipment supports 45 via another support member. The license plate support bracket 102 may be supported by the pair of rear equipment supports 45 via another support member. The reflecting portion 101 may be located at the same height as the wheel axle 41 of the rear wheel 4 in the vertical direction, or may be located below the wheel axle 41 of the rear wheel 4. The license plate support bracket 102 may be located at the same height as the wheel axle 41 of the rear wheel 4 in the vertical direction, or may be located below the wheel axle 41 of the rear wheel 4. The reflecting portion 101 may be located below the license plate support bracket 102. The lighting device 103 may be located at the same height as the wheel axle 41 of the rear wheel 4 in the vertical direction, or may be located below the wheel axle 41 of the rear wheel 4.
[0115] 4 and 5, the rear equipment 100 is located between the left and right centers of the left and right foot rests 811 and 821 when the lean vehicle 1 is viewed from behind. This allows the rear equipment 100 to be disposed in the left and right center of the lean vehicle 1. This prevents the rear equipment 100 from getting in the way when the driver gets on and off the lean vehicle 1. In addition, in FIGS. 4 and 5, a center line passing through the left and right center of the left foot rests 811 and extending in the front and rear directions is indicated by C1, and a center line passing through the left and right center of the right foot rests 821 and extending in the front and rear directions is indicated by C2.
[0116] 4, the rear equipment 100 is located at the rear of the lean vehicle 1 when viewed from above. Specifically, a distance L2 in the front-rear direction between the rear end of the left foot rest 811 and the front end of the rear equipment 100 is greater than half the length L1 of the left foot rest 811 in the front-rear direction, and a distance L4 in the front-rear direction between the rear end of the right foot rest 821 and the front end of the rear equipment 100 is greater than half the length L3 of the right foot rest 821 in the front-rear direction.
[0117] This allows the rear equipment 100 to be positioned at the rear of the lean vehicle 1 so that space is secured on the left and right sides of the rear wheel 4 of the lean vehicle 1, and between the left foot rest 811 and the right foot rest 821 and the rear equipment 100 when viewed from the left and right direction of the lean vehicle 1.
[0118] Incidentally, when a driver gets into the lean vehicle 1, the driver gets into the lean vehicle 1 from behind. When the driver gets into the lean vehicle 1 from behind, the driver needs to position the driver's feet on the left and right of the rear wheels 4 of the lean vehicle 1. Therefore, it is necessary to secure a space on the left and right of the rear wheels 4 of the lean vehicle 1 in which the driver can position his or her feet.
[0119] Therefore, by ensuring spaces between the left foot rest 811 and the right foot rest 821 and the rear equipment 100 on the left and right sides of the rear wheel 4 of the lean vehicle 1, it is possible to ensure spaces S (see cross hatching in FIG. 4) for placing the feet of the driver on the left and right sides of the rear wheel 4 of the lean vehicle 1 when the driver gets on the lean vehicle 1 as described above. Therefore, when the driver gets on the lean vehicle 1, the driver can easily put his / her left foot on the left foot rest surface 811a and the right foot on the right foot rest surface 821a.
[0120] Note that half L1 of the front-rear length of the left foot rest 811 may be equal to half L3 of the front-rear length of the right foot rest 821, or may be different from half L3 of the front-rear length of the right foot rest 821. The front-rear distance L2 between the rear end of the left foot rest 811 and the front end of the rear accessory 100 may be equal to the front-rear distance L4 between the rear end of the right foot rest 821 and the front end of the rear accessory 100, or may be different from the front-rear distance L4 between the rear end of the right foot rest 821 and the front end of the rear accessory 100.
[0121] As shown in FIG. 5, the vertical height H1 of the upper end of the rear equipment 100 relative to the left foot rest surface 811a of the left foot rest portion 811 is lower than the vertical height H2 of the left foot rest surface 811a of the left foot rest portion 811 relative to the ground, and the vertical height H3 of the upper end of the rear equipment 100 relative to the right foot rest surface 821a of the right foot rest portion 821 is lower than the vertical height H4 of the right foot rest surface 821a of the right foot rest portion 821 relative to the ground.
[0122] As a result, when the driver gets into the lean vehicle 1, with one foot placed on one of the left foot placing surface 811a and the right foot placing surface 821a, the driver can easily place the other foot on the other of the left foot placing surface 811a and the right foot placing surface 821a. Therefore, when the driver gets into the lean vehicle 1, the driver can easily place the left foot on the left foot placing surface 811a and the right foot on the right foot placing surface 821a.
[0123] In addition, the upper end of the rear equipment 100 is located lower than the upper end of the rear fender 42. This prevents the rear equipment 100 from coming into contact with the driver's feet when the driver gets into the lean-to vehicle 1.
[0124] In this embodiment, the upper end of the rear equipment 100 means the upper end of a portion of the rear equipment 100 that is located below an area through which the feet of the driver pass when the driver gets into the lean-back vehicle 1. In addition, in the case where the rear equipment 100 includes a plurality of parts, it means the upper end of the uppermost portion that is located below an area through which the feet of the driver pass when the driver gets into the lean-back vehicle 1.
[0125] The lean vehicle 1 of this embodiment includes a body frame 21, a left front wheel 31 disposed to the left of the body frame 21 in the left-right direction of the body frame 21, a right front wheel 32 disposed to the right of the body frame 21 in the left-right direction of the body frame 21, a rear wheel 4 located behind the left front wheel 31 and the right front wheel 32 and rotatably supported by the rear of the body frame 21, a link mechanism 5 supported by the front of the body frame 21 and allowing left and right tilting in the left-right direction of the body frame 21, a left foot rest 811 having a left foot rest surface 811a on which the driver's left foot is placed and located between the left front wheel 31 and the rear wheel 4, and a front The load transfer mechanism 8 has a right foot rest surface 821a on which the driver's right foot is placed, and a right foot rest portion 821 located between the right front wheel 32 and the rear wheel 4, and is capable of transferring a load to a left section of the link mechanism 5 via the left foot rest portion 811 and a right section of the link mechanism 5 via the right foot rest portion 821, or a left section of the link mechanism 5 via the right foot rest portion 821 and a right section of the link mechanism 5 via the left foot rest portion 811, and a rear accessory 100 that is supported on the rear of the body frame 21 and does not include a rear fender that covers at least a portion of an upper part of the rear wheel 4. The rear equipment 100 is positioned at the rear of the lean vehicle 1 so that the front-to-rear distance L2 between the rear end of the left foot rest 811 and the front end of the rear equipment 100 is greater than half the front-to-rear length L1 of the left foot rest 811, and the front-to-rear distance L4 between the rear end of the right foot rest 821 and the front end of the rear equipment 100 is greater than half the front-to-rear length L3 of the right foot rest 821. The rear equipment 100 is located at the rear of the lean-to vehicle 1 so that a vertical height H1 of the upper end of the rear equipment 100 relative to the left foot rest surface 811a of the left foot rest portion 811 is lower than a vertical height H2 of the left foot rest surface 811a of the left foot rest portion 811 relative to the ground, and a vertical height H3 of the upper end of the rear equipment 100 relative to the right foot rest surface 821a of the right foot rest portion 821 is lower than a vertical height H4 of the right foot rest surface 821a of the right foot rest portion 821 relative to the ground. The rear equipment 100 is located between the horizontal center of the left foot rest portion 811 and the horizontal center of the right foot rest portion 821 when the lean-to vehicle 1 is viewed from behind.
[0126] When a driver gets into the lean vehicle 1 described above, the driver gets into the lean vehicle 1 from behind. When the driver gets into the lean vehicle 1 from behind, the driver needs to position the driver's feet on the left and right of the rear wheels 4 of the lean vehicle 1. Therefore, it is necessary to secure a space on the left and right of the rear wheels 4 of the lean vehicle 1 in which the driver can position his or her feet.
[0127] In contrast, in the above-described configuration, the rear equipment 100 is located at a position separated in the front-rear direction from the left foot rest 811 and the right foot rest 821, and is located between the left and right centers of the left and right foot rest 811 and the right foot rest 821 when the lean vehicle 1 is viewed from behind. This makes it possible to secure spaces S for placing the driver's feet on the left and right of the rear wheels 4.
[0128] Moreover, the vertical height H1 of the upper end of the rear equipment 100 relative to the left foot rest surface 811a of the left foot rest portion 811 is lower than the vertical height H2 of the left foot rest surface 811a of the left foot rest portion 811 relative to the ground, and the vertical height H3 of the upper end of the rear equipment 100 relative to the right foot rest surface 821a of the right foot rest portion 821 is lower than the vertical height H4 of the right foot rest surface 821a of the right foot rest portion 821 relative to the ground. This prevents the rear equipment 100 from getting in the way when the driver gets into the lean vehicle 1.
[0129] Therefore, in a lean vehicle 1 having a left front wheel 31 and a right front wheel 32, a configuration can be obtained in which the left foot can be easily placed on the left foot placement portion 811 of the load transfer mechanism 8, and the right foot can be easily placed on the right foot placement portion 821 of the load transfer mechanism 8.
[0130] The lean vehicle 1 of this embodiment further includes a rear fender left support portion 43 and a rear fender right support portion 44 that support at least one of the rear fender 42 and the rear equipment 100 relative to the vehicle body frame 21.
[0131] This allows at least one of the rear fender 42 and the rear equipment 100 to be supported by the vehicle body frame 21. Therefore, a configuration in which the rear fender 42 and the rear equipment 100 are disposed at the rear of the lean-to vehicle 1 can be easily realized.
