Summary of the Invention

Problems to be Solved by the Invention

[0004] In the vehicle of Patent Document 1, the left and right wheels are arranged at a certain interval in the vehicle width direction. Therefore, it is difficult to park the vehicle in a small space, which reduces convenience.

[0005] The present invention has been made in view of the above circumstances, and an object thereof is to provide a vehicle that can be easily parked in a compact space.

Means for Solving the Problems

[0006] The problems to be solved by the present invention are as described above. Next, the means for solving this problem and its effects will be described.

[0007] According to an aspect of the present invention, a front two-wheel saddle-riding type vehicle having the following configuration is provided. That is, the front two-wheel saddle-riding type vehicle includes a frame, a first front wheel, a second front wheel, a rear wheel, a handle, a steering rod, an arm member, and a front wheel distance changing mechanism. The first front wheel is supported by the frame and is located on a first side in the vehicle width direction. The second front wheel is supported by the frame and is located on a second side which is opposite to the first side with the vehicle width direction center interposed therebetween. The rear wheel is supported by the frame. The handle is supported by the frame via a handle shaft and steers the first front wheel and the second front wheel. The steering rod is connected to the handle shaft and turns the first front wheel and the second front wheel in conjunction with the operation of the handle. The arm member extends from the center in the vehicle width direction to the first side and the second side, and supports the first front wheel on the first side and the second front wheel on the second side. The front wheel distance changing mechanism changes the vehicle width direction distance between the first front wheel and the second front wheel by changing the vehicle width direction dimension of the arm member. The frame has a base portion and a handle support portion. The base portion extends in the vehicle length direction between the first front wheel, the second front wheel, and the rear wheel, and supports the first front wheel, the second front wheel, and the rear wheel. The handle support portion extends upward from the base portion and supports the handle via the handle shaft. The first front wheel is supported by the arm member so as to be turnable about a first turning axis located on the first side. The second front wheel is supported by the arm member so as to be turnable about a second turning axis located on the second side. The handle shaft is mechanically connected to the first front wheel and the second front wheel at least via the steering rod. The steering rod turns the first front wheel about the first turning axis and turns the second front wheel about the second turning axis in conjunction with the operation of the handle. The steering rod is configured to be able to release the mechanical connection between the handle shaft and the first front wheel and the second front wheel. The arm member includes an upper arm and a lower arm, with the left ends of the upper and lower arms being coupled to each other by a left support member and the right ends of the upper and lower arms being coupled to each other by a right support member. The upper arm and the lower arm, together with the left support member and the right support member, constitute a parallel link mechanism attached to the handle support portion. Each of the upper arm and the lower arm has a first portion on the center side in the vehicle width direction and a pair of left and right second portions on the outer side in the vehicle width direction that are connected to the first portion and support the first front wheel and the second front wheel, respectively. The front wheel distance changing mechanism changes the vehicle width direction dimension of each of the upper arm and the lower arm by rotating the second portion with respect to the first portion for each of the upper arm and the lower arm.

[0008] Thereby, for example, at the time of parking, the distance between the first front wheel and the second front wheel can be reduced. Therefore, it is possible to park in a narrow and compact space.In addition, the vehicle width direction distance between the first front wheel and the second front wheel can be changed in a state where the mechanical restraint by the steering rod is removed. Therefore, the work can be carried out smoothly.

Modes for Carrying Out the Invention

[0013] Next, embodiments of the present invention will be described with reference to the drawings. First, with reference to FIGS. 1 and 2, an overview of a three-wheeled vehicle 1 according to an embodiment of the present invention will be described. FIG. 1 is a perspective view showing the three-wheeled vehicle 1 according to the first embodiment. FIG. 2 is a perspective view showing the normal state of the three-wheeled vehicle 1. FIG. 3 is a perspective view showing the bent state of the three-wheeled vehicle 1.

[0014] In the following description, the left-right direction of the three-wheeled vehicle 1 is defined in the direction seen from the driver riding on the three-wheeled vehicle 1. Therefore, in the state where the three-wheeled vehicle 1 is upright as shown in FIG. 1, the front-rear direction coincides with the vehicle length direction, and the left-right direction coincides with the vehicle width direction. Also, the up-down direction (vertical direction) coincides with the height direction.

[0015] The two-wheeled vehicle at the front according to the present embodiment is a three-wheeled vehicle (straddle-type vehicle) 1. The three-wheeled vehicle 1 includes two front wheels 2 and 3 on the front side (one side in the vehicle length direction) and one rear wheel 4 on the rear side (the other side in the vehicle length direction).

[0016] The three-wheeled vehicle 1 includes a vehicle body 10. The vehicle body 10 supports a left front wheel (first front wheel, first wheel) 2, a right front wheel (second front wheel, second wheel) 3, and a rear wheel 4.

[0017] The vehicle body 10 includes a frame 11 that serves as the skeleton of the three-wheeled vehicle 1. The frame 11 includes a base portion 11a, a seat support portion 11b, and a handle support portion 11c.

[0018] The base portion 11a extends in the vehicle length direction between the front wheels 2, 3 and the rear wheel 4 and supports the front and rear wheels. The seat support portion 11b extends upward from the base portion 11a and supports the seat 15. The handle support portion 11c extends upward from the base portion 11a and supports the handle 12.

[0019] In this embodiment, the three-wheeled vehicle 1 is a type of leaning vehicle. A leaning vehicle means a vehicle in which the posture of the vehicle body 10 with respect to the road surface can be changed, and the vehicle body 10 is in an inclined state with respect to the road surface along with turning travel by steering.

[0020] In FIG. 1, the three-wheeled vehicle 1 is in a state where the handle 12 for steering is operated to the neutral position and the vehicle body 10 is upright with respect to the road surface (in other words, in a state of normal straight-ahead travel). Hereinafter, unless otherwise specified, the description will be made on the premise of this state.

[0021] The left front wheel 2 and the right front wheel 3 are arranged adjacent to each other with a space therebetween in the vehicle width direction. In this embodiment, each of the front wheels 2, 3 functions as a driven wheel. The left front wheel 2 and the right front wheel 3 are supported at the front portion of the frame 11 so that the posture of the vehicle body 10 with respect to the road surface can be changed. Each of the front wheels 2, 3 functions as a steering wheel and changes its direction according to the turning operation of the handle 12.

[0022] A parallel link mechanism 14 is attached to the handle support portion 11c. The parallel link mechanism 14 includes an upper arm 5 (arm member), a lower arm (arm member) 6, a left support member 7, and a right support member 8. The upper arm 5, the lower arm 6, the left support member 7, and the right support member 8 are coupled in a parallelogram shape by appropriate bearings.

[0023] In the three-wheeled vehicle 1 of the present embodiment, the handle support portion 11c and a handle shaft 17 described later are arranged in a rearwardly inclined manner. Correspondingly, the parallelogram formed in the parallel link mechanism 14 is also arranged in a rearwardly inclined manner. However, the parallel link mechanism 14 may be arranged vertically or forwardly inclined.

[0024] The upper arm 5 and the lower arm 6 are arranged parallel to each other and are rotatably supported by the handle support portion 11c. The left ends of the upper arm 5 and the lower arm 6 are coupled to each other by the left support member 7, and the right ends are coupled to each other by the right support member 8.

[0025] Due to this parallel link structure, in a front view, the postures of the front wheels 2 and 3 change in conjunction with the change in the posture of the base portion 11a.

[0026] The left support member 7 rotatably supports the left front wheel 2. The left support member 7 can turn left and right about a left turning shaft (first turning shaft) 7c extending in the vertical direction with respect to the upper arm 5 and the lower arm 6.

[0027] The right support member 8 rotatably supports the right front wheel 3. The right support member 8 can turn left and right about a right turning shaft (second turning shaft) 8c extending in the vertical direction with respect to the upper arm 5 and the lower arm 6.

[0028] A handle shaft 17 is fixed to the handle 12. The handle shaft 17 extends downward from the handle 12 and is inserted into the cylindrical handle support portion 11c. The handle shaft 17 projects downward from the handle support portion 11c, and a transmission arm 18 is fixed to this portion. The transmission arm 18 turns left and right integrally with the handle 12.

[0029] In order to connect the transmission arm 18 to the left support member 7 and the right support member 8, a steering rod 19 is provided. Thereby, the left front wheel 2 and the right front wheel 3 can be turned in conjunction with the operation of the steering wheel 12. The transmission arm 18 and the steering rod 19 constitute an interlocking mechanism 26 that turns the left front wheel 2 and the right front wheel 3 in conjunction with the operation of the steering wheel 12.

[0030] The steering rod 19 is configured to be detachable from the transmission arm 18, the left support member 7, and the right support member 8 by an appropriate method such as a screw. Therefore, the driver can release the mechanical connection of the transmission arm 18, the left support member 7, and the right support member 8 by removing the steering rod 19 as needed.

[0031] The rear wheel 4 is disposed at the center position of the vehicle body 10 in the vehicle width direction. The rear wheel 4 is rotatably supported by the rear part of the frame 11. In the present embodiment, the rear wheel 4 functions as a drive wheel that transmits the running driving force to the road surface.

[0032] The three-wheeled vehicle 1 includes a seat 15, left and right pedals (operating elements) 16, an electric motor 21 that functions as a prime mover, a battery 22, and a controller (control unit) (not shown).

[0033] The seat 15 is provided above the middle portion in the vehicle length direction of the frame 11. The driver can sit astride the seat 15 and place his feet on the left and right pedals 16.

[0034] The left and right pedals 16 are provided below the seat 15. The force applied by the driver sitting astride the seat 15 to step on the pedal 16 with his foot can be transmitted to the rear wheel 4, and the rear wheel 4 can be rotationally driven manually. Therefore, the three-wheeled vehicle 1 includes a mechanism as a so-called bicycle that is driven to run by the driver's manual power.

[0035] In this embodiment, the electric motor 21 is provided on the axle portion of the rear wheel 4. The electric motor 21 can transmit power to the drive wheels in a state where no driving force is applied by the driver. In addition, the electric motor 21 can also transmit power to the drive wheels in addition to the state where the driving force is applied by the driver. That is, in this embodiment, the three-wheeled vehicle 1 functions as an electric vehicle that can travel without requiring the driving force of the driver, and also functions as an electric assist bicycle that electrically assists the driving by the driver.

[0036] The battery 22 is provided on the lower side of the middle part in the front-rear direction of the frame 11. The battery 22 can supply electric power to the electric motor 21 and various auxiliary devices.

[0037] The three-wheeled vehicle 1 is provided with an accelerator lever (operating element) 13 that can be manually operated by the driver. The accelerator lever 13 is disposed, for example, in the vicinity of the handle 12. When the three-wheeled vehicle 1 travels in the electric vehicle mode, the electric motor 21 is controlled by the driver operating the accelerator lever 13. On the other hand, when the three-wheeled vehicle 1 travels in the bicycle mode, the electric motor 21 is controlled based on the pedaling force applied by the driver to the pedal 16.

[0038] A pair of left and right hinge mechanisms 9 are provided on each of the upper arm 5 and the lower arm 6. The hinge mechanism 9 is disposed at an intermediate portion in the longitudinal direction of the upper arm 5 or the lower arm 6. The hinge mechanism 9 connects a portion located at the intermediate portion in the longitudinal direction of the upper arm 5 or the lower arm 6 and a portion located at the longitudinal end portion via a hinge.

[0039] When the three-wheeled vehicle 1 travels, as shown in FIGS. 1 and 2, the parallel link mechanism 14 is in a state where the upper arm 5 and the lower arm 6 are extended linearly. For example, when parking or storing, the left and right outer portions of the upper arm 5 and the lower arm 6 can be bent as shown in FIG. 3 by rotating approximately 90° forward about the hinge mechanism 9. Thereby, a state where the dimension in the vehicle width direction of the upper arm 5 and the lower arm 6 is reduced can be realized.

[0040] When comparing the vehicle width direction distance L1 between the left front wheel 2 and the right front wheel 3 in the normal state shown in FIG. 2, the vehicle width direction distance L2 between the left front wheel 2 and the right front wheel 3 in the bent state shown in FIG. 3 is smaller (L2 < L1). The above vehicle width direction distances L1 and L2 can also be referred to as the tread width.

[0041] Thus, the hinge mechanism 9 constitutes a front wheel distance changing mechanism 25 that changes the vehicle width direction distance between the left front wheel 2 and the right front wheel 3. The front wheel distance changing mechanism 25 can also be referred to as a distance changing mechanism. By setting the upper arm 5 and the lower arm 6 of the parallel link mechanism 14 in the bent state of FIG. 3, the three-wheeled vehicle 1 can be easily parked in a narrow space. Therefore, the three-wheeled vehicle 1 of the present embodiment can be easily parked in a parking lot for ordinary (two-wheeled) bicycles, and has excellent convenience.

[0042] In the present embodiment, the left front wheel 2 and the right front wheel 3 function as driven wheels. The left front wheel 2 and the right front wheel 3 are provided on the opposite side in the front-rear direction from the rear wheel 4. Therefore, when changing the vehicle width direction distance between the left front wheel 2 and the right front wheel 3, a configuration for disconnecting / connecting power transmission is not required.

[0043] Each of the four hinge mechanisms 9 is provided with a locking mechanism that locks in either the normal state shown in FIG. 2 or the bent state shown in FIG. 3. The locking method is arbitrary, but in the present embodiment, it is configured to perform locking using a locking pin.

[0044] The hinge axis of the hinge mechanism 9 (in other words, the axis around which the upper arm 5 and the lower arm 6 bend) is generally oriented in the vertical direction. This hinge axis is parallel to the plane of the parallelogram in the parallel link mechanism 14.

[0045] The aforementioned steering rod 19 is configured to be detachable from the vehicle body 10. When deforming from the normal state of FIG. 2 to the bent state of FIG. 3, the driver removes the steering rod 19 from the vehicle body 10 by an appropriate method. As a result, the turning of the left front wheel 2 and the right front wheel 3 becomes free, so that as shown in FIG. 3, even in the bent state, the axles of the left front wheel 2 and the right front wheel 3 can be directed along the vehicle width direction. As a result, miniaturization in the vehicle width direction in the bent state can be easily achieved. It is preferable that a place where the removed steering rod 19 can be temporarily stored during parking is provided in the three-wheeled vehicle 1. When the parking is finished and the three-wheeled vehicle 1 is returned to the normal state of FIG. 2, the steering rod 19 is attached to the transmission arm 18, the left support member 7, and the right support member 8 again.

[0046] As described above, the three-wheeled vehicle 1 of the present embodiment includes a left front wheel 2, a right front wheel 3, and a front wheel distance changing mechanism 25. The left front wheel 2 is located on the left side in the vehicle width direction. The right front wheel 3 is located on the right side, which is the opposite side across the center in the vehicle width direction from the left side. The front wheel distance changing mechanism 25 changes the vehicle width direction distance between the left front wheel 2 and the right front wheel 3.

[0047] Thereby, for example, at the time of parking, the distance between the left front wheel 2 and the right front wheel 3 can be reduced. Therefore, it is possible to park in a narrow and compact space.

[0048] The three-wheeled vehicle 1 of the present embodiment includes an upper arm 5 and a lower arm 6 extending from the center in the vehicle width direction to the left and right sides. The front wheel distance changing mechanism 25 changes the vehicle width direction dimensions of the upper arm 5 and the lower arm 6.

[0049] Thereby, by reducing the dimensions of the upper arm 5 and the lower arm 6, the distance between the left front wheel 2 and the right front wheel 3 can be effectively reduced.

[0050] In the three-wheeled vehicle 1 of the present embodiment, the front wheel distance changing mechanism 25 includes a hinge mechanism 9 disposed on the upper arm 5 and the lower arm 6.

[0051] As a result, the vehicle width dimensions of the upper arm 5 and the lower arm 6 can be changed with a simple configuration.

[0052] The three-wheeled vehicle 1 of the present embodiment includes a handle 12 and an interlocking mechanism 26. The handle 12 is operated to turn the left front wheel 2 about the left turning axis 7c located on the left side and to turn the right front wheel 3 about the right turning axis 8c located on the right side. The interlocking mechanism 26 turns the left front wheel 2 and the right front wheel 3 in conjunction with the operation of the handle 12. The interlocking mechanism 26 can release the interlock of the left front wheel 2 and the right front wheel 3 with respect to the operation of the handle 12 by removing the steering rod 19 as shown in FIG. 3.

[0053] As a result, the vehicle width distance between the left front wheel 2 and the right front wheel 3 can be changed in a state where the mechanical restraint by the interlocking mechanism 26 is removed. Therefore, the work can be carried out smoothly.

[0054] Next, a second embodiment will be described. FIG. 4 is a perspective view of a three-wheeled vehicle 1x according to the second embodiment. In the description of the present embodiment, members that are the same as or similar to those in the foregoing embodiment may be denoted by the same reference numerals in the drawings, and the description may be omitted.

[0055] In the three-wheeled vehicle 1x shown in FIG. 4, the front wheel distance changing mechanism 25x includes a telescopic mechanism 9x instead of the hinge mechanism 9. The telescopic mechanism 9x can extend and contract the upper arm 5 or the lower arm 6. The configuration of the telescopic mechanism 9x is arbitrary, but in the present embodiment, it is configured by a slide mechanism in which a small-diameter rod is slidably inserted into a large-diameter pipe.

[0056] By extending and contracting the telescopic mechanism 9x, it is possible to switch between a normal state in which the upper arm 5 and the lower arm 6 are extended and a retracted state in which they are contracted. As a result, the vehicle width distance between the left front wheel 2 and the right front wheel 3 can be changed.

[0057] As described above, in the three-wheeled vehicle 1x of the present embodiment, the front wheel distance changing mechanism 25x includes a telescopic mechanism 9x that extends and contracts the upper arm 5 and the lower arm 6.

[0058] Accordingly, with a simple configuration, the vehicle width direction dimensions of the upper arm 5 and the lower arm 6 can be changed. Further, compared with the configuration in which the upper arm 5 and the lower arm 6 are bent as in the first embodiment, interference with surrounding members is less likely to occur.

[0059] Although the preferred embodiments of the present invention have been described above, the above configuration can be changed, for example, as follows. The changes may be made individually or a plurality of changes may be arbitrarily combined.

[0060] In the first embodiment, the direction in which the upper arm 5 and the lower arm 6 are bent via the hinge mechanism 9 may be backward instead of forward. As described above, when the upper arm 5 and the lower arm 6 are bent forward, it is easy to position the center of gravity of the three-wheeled vehicle 1 between the front and rear wheels, so the stability of the three-wheeled vehicle 1 can be enhanced. When the upper arm 5 and the lower arm 6 are bent backward, the longitudinal dimension of the three-wheeled vehicle 1 is less likely to increase, so it can be easily parked even in a small space.

[0061] In the first embodiment, the angle by which the upper arm 5 and the lower arm 6 are bent by the hinge mechanism 9 may be greater than or less than 90°.

[0062] In the bent state (FIG. 3) of the first embodiment, instead of making the directions of the axles of the left front wheel 2 and the right front wheel 3 parallel to the vehicle width direction, they can be set to any direction.

[0063] Instead of the hinge mechanism 9 and the telescopic mechanism 9x, a connecting structure may be provided between the upper arm 5 and the lower arm 6. In the connecting structure, the left and right outer portions of the upper arm 5 and the lower arm 6 are configured to be detachable from the central portion. This configuration can be realized, for example, by changing such that all the rods can be pulled out from the cylinder in the telescopic mechanism 9x of the second embodiment. As a configuration for detachably connecting members, for example, screws, pins, etc. can be considered, but it is not limited thereto. By separating the left and right outer portions (including the left front wheel 2 and the right front wheel 3) of the upper arm 5 and the lower arm 6 and attaching them to an arbitrary location of the vehicle, a state where the vehicle width direction distance between the left front wheel 2 and the right front wheel 3 is reduced can be realized.

[0064] In the three-wheeled vehicles 1, 1x, a load basket may be arranged so as to be located between the left front wheel 2 and the right front wheel 3 in a plan view. It is preferable to arrange the load basket above the left front wheel 2 and the right front wheel 3 because interference with the load basket can be prevented even when the vehicle width direction distance between the left front wheel 2 and the right front wheel 3 is reduced.

[0065] In the first embodiment, the hinge mechanism 9 is locked manually by a lock pin. Instead of this, for example, a lock mechanism driven by a solenoid may be provided, and the lock / lock release may be switched electrically. In this case, it is preferable that the controller for controlling the solenoid detects by some means that the vehicle is in a stopped state and sets this as a condition for unlocking. The stopped state of the vehicle can be determined, for example, by the output of a sensor that detects the rotation of the front wheels 2, 3 or the rear wheel 4. Further, the unlocking of the lock mechanism may be performed in conjunction with the use of, for example, a side stand, a parking brake, or a lean lock brake. The same applies to the telescopic mechanism 9x of the second embodiment.

[0066] In the above-described embodiments, the front-wheel track changing mechanisms 25 and 25x can also be applied to a configuration in which the arm member rotates about the handle support portion 11c together with the handle 12, and the front wheels are supported at the left and right ends of this arm member. In this case, a hinge mechanism or a telescopic mechanism may be provided on the arm member. The arm member that rotates together with the handle 12 can be arranged as only one instead of two in the vertical direction.

[0067] The middle portion in the longitudinal direction of the steering rod 19 may be configured to be separable / connectable. Instead of removing the steering rod 19 from the three-wheeled vehicle 1 or 1x, the interlock between the left front wheel 2 and the right front wheel 3 with respect to the operation of the handle 12 can also be released by disconnecting the middle portion of the steering rod 19.

[0068] Instead of the lean type, the front-wheel track changing mechanism 25 can also be applied to a non-lean type vehicle in which the parallel link mechanism 14 is omitted.

[0069] The mechanism for changing the distance between the left and right wheels can also be applied to the rear wheels of a vehicle having two rear wheels.
