The exhaust gas is combusted by the generating engine 22, and exhaust gas is discharged outside through an exhaust pipe 24 extending from the power generating engine 22 and a muffler 25 connected to the rear end of the exhaust pipe 24. The vehicle is transmitted to the front wheel 11 and / or the rear wheel 13 that is rotatably attached to the rear lower portion of the vehicle body frame 21 and is rotatably attached to the front upper portion of the vehicle body frame 21. This is a small vehicle that can be steered by a steering shaft 26 and a steering handle 15 that rotates the steering shaft 26.

  The power generation engine 22 may be of any type as long as it is a drive source such as a gasoline engine, diesel engine, or electric motor.

  When the front wheel 11 and the rear wheel 13 are wide and low pressure special tires called balloon tires, the low pressure tire deforms and absorbs the unevenness of the road surface, and even if the road surface is weak, the wide tires sink. Since it can suppress, such a vehicle 10 is called a rough terrain vehicle.

The power generated by the power generation engine 22 is transmitted to the final reduction gear 29 by a power transmission device 28 such as a propeller shaft as shown in FIG.
Then, as shown in FIG. 5, the power is transmitted from the final reduction gear 29 to the front wheel 11 via the drive shaft 31 extending in the vehicle width direction, and the front wheel 11 is rotationally driven.

  The tie rod 46 is connected to the output shaft of the power steering unit 47 as shown in FIG. The power steering unit 47 is fastened by bolts 48, 48 with a front tension bracket 58L indicated by an imaginary line.

As shown in FIG. 6, the vehicle body frame 21 is structurally characterized in that the upper tension pipe 56 can be removed from the first cross portion 53 and the second cross portion 55. As a result, when the vehicle-mounted product such as the power generation machine 22 is mounted, the vehicle-mounted product, which is a heavy object, can be lowered into the vehicle body frame 21 from above by removing the upper tension pipe 56.
Therefore, according to the present invention, there is provided a vehicle having a body frame in which in-vehicle products can be easily taken in and out.

  In addition, an auxiliary equipment support portion 77 that supports auxiliary equipment such as the air cleaner 23 and the battery 78 and an electrical equipment support portion 81 that supports electrical equipment such as the ignition coil 79 are attached to the upper tension pipe 56. Sub-assemblies are possible by centrally arranging auxiliary equipment and electrical equipment. Further, by removing the upper tension pipe 56, it is possible to remove auxiliary equipment, electrical components, and the like from the vehicle body frame 21 collectively, and maintenance and inspection are facilitated.

The structure of the vehicle body frame 21 that can exhibit such operational effects will be described in detail below.
As shown in FIG. 7, the vehicle body frame 21 has a pair of left and right main frames 51 </ b> L and 51 </ b> R (L) that pass under the power generation engine (FIG. 6, reference numeral 22) in the vehicle front-rear direction and the rear part is curved upward. Indicates a left when viewed from the occupant, R is a subscript indicating the right, and the same applies hereinafter) and a pipe or frame extending upward from the front portion of the main frames 51L and 51R. Left and right front wheel suspension support portions 52L, 52R, a first cross portion 53 extending in the vehicle width direction from the left front wheel suspension support portion 52L to the right front wheel suspension support portion 52R, and the left main A second cross portion 55 that extends in the vehicle width direction from the curved portion 54L at the rear of the frame 51L to the curved portion 54R at the rear of the right main frame 51R and the power generation engine passes in the vehicle front-rear direction, and the front end But Serial attached removably to the first cross portion 53, an upper tension pipe 56 trailing end is attached removably to the second cross portion 55, is referred to as key elements.

The upper tension pipe 56 is formed such that the rear portion is bent obliquely downward.
The front wheel suspension support portion 52L includes a front pipe portion 57L that extends upward from the main frame 51L, a front tension bracket portion 58L that reinforces the front pipe portion 57L obliquely across the upper portion of the front pipe portion 57L and the main frame 51L, Consists of. The front wheel suspension support portion 52R also includes a front pipe portion 57R and a front tension bracket portion 58R.

  Bolt holes 62 and 62 used for fastening the power steering unit (FIG. 4, reference numeral 47) are provided in the front tension bracket portion 58L. The front wheel suspension support portion 52R also includes a front pipe portion 57R and a front tension bracket portion 58R.

The upper ends of the pair of left and right front pipe portions 57L and 57R are connected by a first cross portion 53, and the first cross portion 53 is configured by a U-shaped pipe portion 59 that opens downward as viewed from the front of the vehicle. The pipe portion 59 is continuous with the left and right front pipe portions 57L and 57R, and the left and right front pipe portions 57L and 57R and the U-shaped pipe portion 59 are formed of a single bent pipe.
Since the left and right front pipe portions 57L, 57R and the U-shaped pipe portion 59 are formed of a single bent pipe, the number of components of the front wheel suspension support portion can be reduced.

Further, a front cushion mounting portion 61 for attaching the front cushion (FIG. 5, reference numeral 41) is provided on the front pipe portions 57L and 57R.
Since the front cushion mounting portion 61 is provided in the vicinity of the first cross portion 53, the force from the front cushion is smoothly transmitted to the vehicle body frame 21 via the first cross portion 53.

A steering shaft 63 extending downward from the steering handle 15 is supported by a front steering shaft bearing portion 64 and a rear steering shaft bearing portion 65 shown in FIG.
The front steering shaft bearing portion 64 is provided at the first cross portion 53, and the rear steering shaft bearing portion 65 is provided at the tip of the upper tension pipe 56.
Then, the rear steering shaft bearing portion 65 is aligned with the front steering shaft bearing portion 64 in the vehicle front-rear direction and coupled with bolts 66, 66, thereby completing the bearing structure.

  That is, by skillfully utilizing the first cross portion 53 and the tip of the upper tension pipe 56, the steering shaft (FIG. 7, reference numeral 63) can be easily supported with a small number of parts.

  Further, as shown in FIG. 7, rear pipes 67L and 67R extend from the upper ends of the curved portions 54L and 54R of the left and right main frames 51L and 51R toward the rear of the vehicle, and the rear pipes 67L and 67R Reinforced by rear sub pipes 68L, 68R extending from the center in the height direction. The front ends of the rear pipes 67L and 67R extend from the rear end of the upper tension pipe 56 to the front of the vehicle in a side view of the vehicle. That is, the front ends of the rear pipes 67L and 67R overlap the rear end of the upper tension pipe 56 in a side view of the vehicle.

One upper tension pipe 56 is provided on the center line of the vehicle body as shown in FIG. 8 which is a plan view of the vehicle body frame. The upper tension pipe 56 does not pass the left and right two to the first cross part 53 and the second cross part 55, but the following effects can be expected by using one.
Since the number of upper tension pipes is one, the weight of the vehicle body frame can be reduced, and in consideration of attachment and removal, the work time of one is shorter.

Further, as shown in FIG. 9 which is a bottom view of the body frame (subscripts L and R are reversed), the distance (outer width) in the vehicle width direction between the left and right main frames 51L and 51R is at the center. The front bent portion 71 and the rear portion are arranged on the left and right main frames 51L and 51R so that the distance between the front portions becomes narrow as W2 (W2 <W1) and the rear interval W3 (W3 <W1). A bent portion 72 is provided.
By narrowing the front, alignment is easily adjusted, and by narrowing the rear, it is easy to ensure riding comfort in a saddle-ride vehicle.

  Furthermore, as shown in FIG. 10, which is a modified view of FIG. 9, the main frame 51L has a front frame F that is smaller in height and width as it goes forward with respect to the center C in the vehicle longitudinal direction. The rear portion R may be configured such that the height and width of the frame become smaller toward the center portion C in the vehicle longitudinal direction. The same applies to the main frame 51R.

Specifically, as shown in FIG. 18 which is a supplementary explanatory view of FIG. 10, the main frame 51L has a central portion C bulging outward in the vehicle width direction, and a front portion F and a rear portion R approaching the vehicle width center. So that it is generally curved. The height H1 of the main frame 51L in the central portion C is large, the height H2 of the front portion F is small (H2 <H1), and the height H3 of the rear portion R is also small (H3 <H1).
Further, the width W4 of the main frame 51L in the central portion C may be large, the width W5 of the front portion F may be small (W5 <W4), and the width W6 of the rear portion R may be small (W6 <W4).

In order to ensure rigidity, the center portion C in the vehicle front-rear direction of the main frames 51L and 51R has a larger frame height and width. Others made the frame height and width small.
In other words, it is possible to improve the ride quality of the vehicle by generating deflection while ensuring the frame rigidity.

Next, the mounting form of the rear cushion will be described.
As shown in FIG. 11, the upper portion of the rear cushion 73 is attached to the rear cushion attachment portion 76. The rear cushion mounting portion 76 is provided in the second cross portion (FIG. 10, reference numeral 55).

Such a rear cushion 73 is arranged obliquely so that the lower part is positioned behind the fuel tank 74 and the lower part is positioned behind the vehicle (the right is the front of the vehicle in the figure). In addition,
Therefore, the rear cushion shaft 75 follows the rear bent shape of the upper tension pipe 56 as shown in FIG. Then, the load on the rear cushion acting in the direction of the rear cushion shaft 75 is smoothly transmitted to and supported by the upper tension pipe 56.
Further, since the upper part of the front pipe part (first cross part 53) is bent so that the upper part is located behind the vehicle, the load applied to the front cushion from the front cushion attaching part 61 is smoothly applied to the upper tension. It is transmitted to the pipe 56 and supported.

Next, the arrangement of auxiliary devices and electrical components placed on the upper tension pipe 56 will be described in detail.
As shown in FIG. 12, a plate-like auxiliary device support portion 77 is placed on the upper tension pipe 56 at the vehicle rear position from the steering handle 15, and an air cleaner / battery storage box 82 is mounted on the auxiliary device support portion 77. Is placed. The air cleaner / battery storage box 82 is narrowed in a triangular shape so that the width of the rear side of the vehicle becomes narrower toward the rear of the vehicle. By narrowing down to a triangular shape, space for passengers to rest was secured.

  The air cleaner / battery storage box 82 is divided into left and right by a partition wall 83 extending in the longitudinal direction of the vehicle body. The right partition is an air cleaner storage portion 84 for storing the air cleaner 23, and the left partition is a battery 78 and the battery storage box 84. An electrical component storage unit 86 that stores small electrical components 85 disposed behind the battery 78 from the vehicle is used. That is, since the air cleaner storage portion 84 and the battery 78 are distributed to the left and right with respect to the upper tension pipe 56, the weight balance is improved.

That is, the air cleaner / battery storage box 82 is one integrated box, but is a box that stores the air cleaner 23, the battery 78, and the small electrical component 85 by partitioning.
A connecting tube 87 is extended from the air cleaner 23 to the right side in the vehicle width direction of one upper tension pipe 56 disposed at the center in the vehicle width direction.

  In addition, a plate-like electrical component support portion 81 is placed on the rear portion of one upper tension pipe 56. An ignition coil 79, an ACG (for AC generator) coupler 88, a change switch coupler 89, a bank angle sensor 107, and the like are mounted on the plate-like electrical component support portion 81.

And as shown in FIG. 13, the main harness 91 passes under the electrical equipment storage part 86, and is extended in the vehicle body front-back direction.
A battery 78 is disposed in the electrical component storage portion 86, and a small electrical component 85 is disposed behind the battery 78.
The small electrical component 85 includes, for example, an EPS fuse 92, a main fuse box 93 disposed behind the EPS fuse 92, a starter magnet switch 94 disposed on the right side of the main fuse box 93 in the vehicle width direction, and a main fuse box. The fuel pump relay 95 is arranged at the rear of the vehicle 93.

An air inlet 105 is provided at the front of the air cleaner storage portion 84 of the air cleaner / battery storage box 82, a regulator 106 is disposed below the air inlet 105, and the heat dissipating fins 106a of the regulator 106 are provided so as to extend in the vertical direction. It has been. Since the longitudinal direction of the radiating fin 106a matches the intake flow direction, the intake resistance can be reduced and the heat dissipation efficiency can be improved.
The air cleaner / battery storage box 82 is fastened and fixed to the upper tension pipe 56 at the bottom of the battery 82 and at the rear end 82a.
Further, the positive terminal 98 of the battery 78, the EPS fuse 92, and the starter magnet switch 94 are connected by a harness 91b, and a harness 91c extending in the vehicle longitudinal direction is connected to the negative terminal 99 of the battery 78.

Next, the form of the air cleaner / battery storage box 82 will be described using the left side view and the right side view.
As shown in FIG. 14, a plate-like auxiliary device support portion 77 is placed on the upper tension pipe 56, and an air cleaner / battery storage box 82 is placed on the auxiliary device support portion 77.
A battery 78 is housed in the air cleaner / battery storage box 82 together with the air cleaner 23. The battery 78 is located behind the head pipe 96 in the vehicle, in front of the seat 17, and in front of the cylinder 97 of the power generation engine 22. 23 is arranged on the left side in the vehicle width direction (front side in the figure).

A positive terminal 98 and a negative terminal 99 of the battery 78 are arranged in the upper part of the air cleaner / battery storage box 82, that is, in the vicinity of the lid 101.
A small electrical component 85 is arranged in the air cleaner / battery storage box 82.
That is, the small electrical component 85 includes an EPS fuse 92, a main fuse box 93 disposed behind the EPS fuse 92, a starter magnet switch 94 disposed under the main fuse box 93, and a vehicle including the main fuse box 93. The fuel pump relay 95 is arranged at the rear.

The vicinity of the middle between the lower end of the lid 101 and the auxiliary equipment support 77 under the lid 101 is set to the inundation upper limit line 102. The inundation upper limit line 102 is set at the lower end of the intake port (FIG. 15, reference numeral 105).
Since most of the + terminal 98 and −terminal 99 of the battery 78 and the small electrical component 85 are disposed above the inundation upper limit line 102, waterproofness can be improved, and electrical components including the battery 78 are not waterproofed. Can be composed of type.
Further, the hose stay 103 is extended downward from the auxiliary equipment support portion 77, and the radiator hose 104 is supported by the hose stay 103. An ECU 117 (see also FIG. 6) is disposed in the air cleaner / battery storage box 82.

In many conventional vehicles, the battery is arranged below the seat 17 and the distance between the battery and the engine around which the electrical components such as sensors are likely to concentrate is increased. It was.
In this respect, in this embodiment, since the battery 78 is disposed in the vicinity of the power generation engine 22, the harness can be shortened. Furthermore, since the small electrical component 85 can also be disposed in the vicinity of the power generation engine 22, the harness including the small electrical component 85 can be shortened.

In addition, many conventional vehicles have a problem that it is necessary to separately provide a battery storage case for storing a battery.
In this respect, in this embodiment, since the battery 78 is also housed in the case (air cleaner / battery storage box 82) in which the air cleaner 23 is stored, the battery storage case can be omitted.
In addition, since the battery 78 and the air cleaner 23 are disposed in front of the cylinder of the power generation engine 22, it is possible to make it less susceptible to the heat of the power generation engine 22, and mud and the like that the rear wheels wind up enter the air cleaner 23. It becomes difficult and preferable.

  Furthermore, as apparent from FIG. 12, the air cleaner 23 is disposed at one of the vehicle body centers and the battery 78 is disposed at the other, so that it is easy to balance the weight between the left and right.

As shown in FIG. 15, the air cleaner / battery storage box 82 includes an intake port 105 on the front side of the vehicle (right side in FIG. 15). A regulator 106 is disposed below the intake port 105. The intake air directly hits the regulator 106 and exhibits the effect of cooling.
Further, since the intake port 105 is provided in front of the air cleaner / battery storage box 82, mud that the rear wheel 13 winds up becomes more difficult to enter, which is preferable.
The regulator 106 is fastened and fixed to a boss provided on the front wall surface of the air cleaner / battery storage box 82.

Next, a supplementary explanation will be given regarding the arrangement of the small electrical components 85.
As shown in FIG. 16, an electrical component support portion 81 is mounted on the upper tension pipe 56, and an ignition coil 79, an ACG coupler 88, a change switch coupler 89, a bank angle sensor 107, etc. are mounted on the plate-shaped electrical component support portion 81. Is placed.

The rear part of the plate-like electrical component support part 81 is supported by the stay 108 of the fuel tank 74. The fuel hose 109 extending from the fuel tank 74 is supported by a guide portion provided at the left edge of the electrical component support portion 81 and extends forward of the vehicle.
The fuel hose 109 is supported by the electrical component support portion 81. If the support portion is left in the vehicle width direction with respect to the upper-tension pipe 56, the main harness 91 is disposed on the right in the vehicle width direction. The fuel hose 109 and the main harness 91 are arranged on the left and right with a good balance with respect to the upper-tension pipe 56.

  Further, seat catchers 111L and 111R are provided at the front ends of the rear pipes 67L and 67R, and the main harness 91 is supported by the clip 112 on the right seat catcher 111R. Further, the main harness 91 is supported on the electrical component support portion 81 via the stay 113 at a position near the ignition coil 79. The stay 113 is provided obliquely by rotating counterclockwise with respect to the longitudinal axis of the vehicle body so that the main harness 91 faces the right rear pipe 67R. As a result, the thick main harness 91 can be smoothly displaced in the vehicle width direction.

In addition, a fuel tank 74 is disposed behind the electric component support portion 81 in the vehicle. The harness can be routed at a position away from the fuel tank 74, and workability is improved.
The rear portion of the electrical component support portion 81 extends in the vehicle width direction along the second cross portion 55 so as to cover the joint portion between the second cross portion 55 and the rear portion of the upper tension pipe 56. In this example, a harness that extends from the rear surface of the AGC coupler 88 and a harness that extends from the rear surface of the change switch coupler 89 are placed on the expanded portion. The welded portion of the second cross portion 55 and the rear portion of the upper tension pipe 56 is likely to generate burrs and protrusions by welding. However, if the coupling portion is covered with the rear portion of the electrical component support portion 81, there is no fear that the harness, the electrical component, or the like is damaged by burrs or protrusions.

  Further, the plate-like electrical component support portion 81 is extended from the rear pipe 67L to the front of the vehicle, and the main harness 91 is supported by the front end of the rear pipe 67R and the front end of the electrical component support portion 81. If you try to route the main harness from the center of the vehicle width to the outside of the vehicle width while bending it in the shape of a crank, not only will the harness length be longer, but the main harness will be relatively thick, making it difficult to bend and poor assembly There are challenges. In this respect, the present embodiment can solve the above-described problem while firmly supporting the main harness 91 with the above-described configuration.

In addition, a cover stay portion 114 for attaching a vehicle body cover is provided on the front left portion of the electrical component support portion 81.
That is, the electrical component support portion 81 also plays a role of supporting the vehicle body cover.

The connecting tube 87 extends from the air cleaner / battery storage box 82 to the rear of the vehicle. First, the connecting tube 87 is lowered while curving to the right in the vehicle width direction at the curved descending portion 116, and then the throttle body disposed on the vehicle body center side. 115 extends to the rear side of the vehicle so as to pass through the side of 115, and then is turned back to the center of the vehicle body by a turn portion 116 of approximately 90 °, and the tip is inserted under the upper tension pipe 56.
The turn part 116 has a large diameter so as to reduce the channel resistance.
That is, the connecting tube 87 is wound so as to surround the throttle body 115 so as to exhibit a substantially J shape in plan view.

That is, as shown in FIG. 15, the connecting tube 87 is lowered by the curved descending portion 116, and the tip is inserted under the upper tension pipe 56.
Further, as shown in FIG. 6, the electrical component support portion 81 is supported by the upper end (upper surface) of the upper tension pipe 56 and forms a step portion at a position lower than the upper end of the upper tension pipe 56. The electrical parts such as the ignition coil 79 are accommodated in the part.

Then, as shown in FIG. 16, the connecting tube 87 and the throttle body 115 are arranged on one side (in the vehicle width direction right side) with respect to the upper tension pipe 56, and on the other side (in the vehicle width direction left side in this example). Since the electrical component support portion 81 is disposed, space can be effectively utilized and the throttle body 115 is not obstructed by the electrical component support portion 81, so that maintainability of the throttle body 115 can be improved.
Further, the exhaust pipe 24 is disposed under the plate-like electrical component support portion 81. Since the electrical component support portion 81 serves as a heat shield, the ignition coil 79, the ACG coupler 88, and the change switch coupler 89 are thermally protected.

As shown in FIG. 17, a seat catcher 111L is provided at the front end of the rear pipe 67L, and the seat 17 is held by the seat catcher 111L.
Further, since the ignition coil 79, the ACG coupler 88, and the change switch coupler 89 are located below the upper surface of the upper tension pipe 56, there is no fear of receiving a downward load on the seat 17.

  Furthermore, since the ACG coupler 88, the change switch coupler 89, the bank angle sensor 107, and the fuel hose 109 are arranged at a position overlapping the rear pipe 67L, there is less concern that the seat 17 will be loaded downward. The protective effect of these electrical components can be enhanced. Furthermore, the electrical component support portion 81 can be efficiently provided in a narrow space under the seat, and the electrical component can be arranged.

  The main harness 91 is supported by the stay 113 at the front portion of the electrical component support portion 81. A throttle body 115 is disposed below the electrical component support portion 81, and an exhaust pipe 24 is disposed below the throttle body 115.

  The body frame structure of the present invention is suitable for small vehicles, particularly rough terrain vehicles, but may be applied to general vehicles.

  The vehicle body frame structure of the present invention is suitable for rough terrain vehicles.
