FIG. 1 shows a side view when the wheel device according to the embodiment of the present invention is mounted on a three-wheeled vehicle of a vehicle body swinging type, and FIG. 2 shows the wheel device of the embodiment of the present invention of the vehicle body swinging type. FIG. 2 is a cross-sectional view taken along the line AA in FIG.
1 and 2 show a three-wheeled vehicle of a vehicle body swing type, but a power source such as an engine or a DC motor is omitted, and the following embodiments are also the same.
As shown in FIGS. 1 and 2, the wheel device 10 according to the embodiment of the present invention is positioned at the left and right centers of the vehicle body 3 of the vehicle body swing type three-wheeled vehicle 1 and extends downward from the chassis 4. An orthogonal shaft 15 that is orthogonal to the longitudinal tilting shaft 13 that is rotatably supported by 14 b is provided, and a cross block is formed by the tilting shaft 13 and the orthogonal shaft 15, and is rotatably attached to the orthogonal shaft 15.

FIG. 3 is a plan view when the vehicle body of the vehicle body swing type three-wheeled vehicle equipped with the wheel device according to the embodiment of the present invention is tilted 25 degrees to the left.
In the case of a three-wheeled vehicle with a vehicle body swing type, it is generally said that the limit of the tilt angle of the vehicle body when turning the vehicle body is around 20 degrees. As shown in FIG. 3, when the vehicle body 3 shown in FIG. 1 is tilted by 25 degrees, the wheels 12a and 12b are also directed to the outside with respect to the turning direction. At that time, the inclination axis 13a of the inclination axis 13 (see FIGS. 1 and 2) intersects the ground at the point (A), and the point (B) is the orthogonal axis 15a of the orthogonal axis 15 (see FIGS. 1 and 2). This is the intersection with the tilt axis 13a. Since the wheels 12a and 12b are always vertical even though the vehicle body is inclined by 25 degrees, the orthogonal axis 15 parallel to the wheels 12a and 12b is horizontal, and the line connecting the centers of the wheels 12a and 12b The central perpendicular line overlaps the inclined line 13a in the plan view.
Therefore, even if the vehicle body swing type three-wheeled vehicle 1 to which the wheel device 10 is mounted is turning with the vehicle body 3 tilted on a flat ground, even if it suddenly stops or suddenly shifts to a low speed, the position of the center of gravity of the occupant (C) is inside the polygon S connecting the ground contact positions of the wheel 21a, the wheel 21b, and the front wheel 21c, and can maintain a stable state and avoid overturning.

When the vehicle body swing type three-wheeled vehicle 1 equipped with the wheel device according to the embodiment of the present invention crosses the slope, the direction of the front wheel 12c is made the same as the direction of the rear wheels 12a and 12b. If the point intersected by the line drawn from the center of gravity (c) at right angles to the traveling direction of the vehicle and the side of the valley side of the contact polygon S is (d), the angle of the limit slope that can be crossed without falling to the valley side is When the straight line (Hani) becomes vertical, as shown in FIG. 17B, when the vehicle body 3 is tilted 25 degrees, the angle of the sloping ground that crosses is about 27 degrees.
Further, in order to compare the case of a self-supporting tricycle that cannot tilt a conventional vehicle body under the same conditions, the limit angle of the slope is obtained by similarly obtaining (d) point as shown in FIG. 17 (c). Thus, the vehicle body swing type three-wheeled vehicle 1 equipped with the wheel device according to the embodiment of the present invention has a significantly large angle of inclination on which the vehicle body 3 is tilted and crossed. .

A front-lowering inclined shaft 113 is rotatably attached to the rear bracket 114a and the front bracket 114b, an orthogonal shaft 115 orthogonal to the inclined shaft 113 is provided, and the inclined shaft 113 and the orthogonal shaft 115 form a cross rotation block. Has been. The vehicle body is composed of the seat 103b and the chassis 104. When the vehicle compartment is provided, the vehicle compartment is also included, and the same applies to the following embodiments.

In the case of a two-wheeled vehicle, as in the case of a three-wheeled vehicle with a vehicle body swing, the tilt angle of the vehicle body when the vehicle is turned with the vehicle body tilted is generally said to be around 20 degrees. As shown in FIG. 6, the tilt axis 113 a of the tilt shaft 113 intersects the ground at the point (A), and the point (B) is the intersection of the orthogonal axis 115 and the tilt axis 113. Since the auxiliary wheels 112 are always vertical even though the vehicle body is inclined by 25 degrees, the orthogonal shaft 115 parallel to the left and right auxiliary wheels 112 is horizontal and the left and right auxiliary wheels facing each other. The vertical line at the center of the line connecting the centers of the wheels 112 overlaps the inclined line 113a in the plan view.

As described in the case of mounting on a two-wheeled motor vehicle, the tilting shaft attached to the wheel device has a slope that rises forward when the traveling wheel or auxiliary wheel is located in front of the orthogonal shaft. In this case, when the vehicle body is tilted, the traveling wheels and auxiliary wheels face inward and move inward, and the center of gravity is a polygon that connects the ground contact positions of the wheels. It can be set to be inside, and even if it stops suddenly while turning, it can be prevented from overturning.

Next, the operation of the fulcrum shaft actuator 60 will be described.
When the operation lever 21 is in the retreat limit position, the stopper 66a of the shaft driving drum 66 is in contact with the inner wall of the U-shaped bracket 61, and the fulcrum shaft 36 is fixed. When the operation lever 21 is moved to the forward limit from the state where the fulcrum shaft 36 is fixed, the operation lever 21 is held at that position. At this time, since the fulcrum shaft 36 is lowered, vibration during traveling is not directly transmitted to the vehicle raising bar 34.

Further explaining this action in detail, when the operation lever 21 is moved forward, the Bowden wire 69 is pulled, and when the piston cylinder 72 advances through the fixed cylinder 70 and reaches the final end, it is assembled to the piston cylinder bracket 74. The received lot 75 is pushed, and the clutch shifter 62 rotates 35 degrees.
When the clutch shifter 62 rotates 35 degrees, the clutch 63 moves against the pressing force of the compression spring 64 and is disengaged from the tooth shape of the U-shaped bracket 61. When the Bowden wire 69 is further pulled in this state, the shifter 62 does not move, the drive drum 66 rotates, the arm rotation drive shaft 68 meshed with the spline rotates, and the arm 65 rotates to lower the fulcrum shaft 36. To do.
The operation lever 21 moved forward is locked when the fulcrum shaft 36 is lowered, but when the release lever (not shown) is operated, the holding of the Bowden wire 69 is released and the fulcrum shaft is reversed. 36 is fixed.

Since the fulcrum shaft operating device 60 can lower the fulcrum shaft 36 during traveling, the vibration is directly transmitted to the vehicle raising bar 34 and can travel comfortably and prevent deterioration.
In addition, the vehicle body raising bar 34 is securely fixed and released by the fulcrum shaft operating device 60, so that the vehicle posture can be secured and controlled quickly.

FIG. 11 is a plan view of a fulcrum shaft actuating device for a body raising bar for a two-wheeled vehicle provided in the wheel device according to the embodiment of the present invention.
As shown in FIG. 11, the wheel device according to the embodiment of the present invention includes an auxiliary wheel in a two-wheeled vehicle. However, the fulcrum shaft actuating device 160 of the vehicle raising bar provided in the wheel device includes The fulcrum shaft 136 of the support bar is rotated and raised to serve as a fulcrum for the vehicle raising bar, and, like the sixth embodiment, is composed of a fulcrum shaft support mechanism 160a and a fulcrum shaft operation mechanism 160b.
Since the fulcrum shaft operating mechanism 160b is the same as that of the sixth embodiment, the description thereof is omitted.
The fulcrum shaft support mechanism 160a includes an arm 175 facing and fixed to both ends of the arm rotation drive shaft 168, and a fulcrum shaft 136 attached to the tip of the arm 175 in parallel with the arm rotation drive shaft 168. The fulcrum shaft 136 is slidably connected to the vehicle raising bar 134 (see FIG. 6) by a cross-shaped slider 124 (see FIG. 6).
Next, the operation of the fulcrum shaft actuator 160 will be described.
When the operation lever 121 attached to the lock shaft turning mechanism 55 of the lock and unlock device 50 of FIG. 9 is in the retreat limit position, the operation lever 121 is held at that position when the operation lever 121 is moved to the advance limit. The At this time, since the arm rotation drive shaft 168 rotates as in the sixth embodiment, the fulcrum shaft 136 moves in the descending direction, but is slidably attached to the vehicle raising bar 134 by the cross-shaped slider 124 as shown in FIG. Therefore, the auxiliary wheel 112 attached to the arm rotation drive shaft 168 can be separated from the ground by the rotation of the arm rotation drive shaft 168 while moving forward along the vehicle body raising bar 134.
When a release lever (not shown) is operated, the holding of the operation lever 121 is released, and the fulcrum shaft is fixed in the reverse order.

  In the fulcrum shaft operating device 160, the fulcrum shaft 136 and the vehicle body raising bar 134 are always slidably coupled and the vehicle body raising bar is in a locked state, so that vibration of the vehicle body raising bar 34 is suppressed during traveling. In addition, since the auxiliary wheels 112 can be separated from the ground, stable running can be achieved.
