Description

[Detailed description of the invention] It relates to a vehicle in which the engine is located between the legs of a driver.

In this type of vehicle, the engine and footrest are each attached to the frame via dedicated support stays, which has the disadvantage of increasing the number of parts, resulting in an increase in cost and weight.

The present invention was made based on these circumstances, and
By making a single support stay provided on the frame double as support for the engine and footrest, the number of parts is increased to 4.
Reduce fLw to reduce weight and cost? The purpose is to provide vehicles such as motorcycles that can be realized.

An embodiment of the present invention will be described below based on drawings in which the present invention is applied to a motorcycle.

1 in Fig. 1 is a frame, and a hollow box-shaped main frame structure 3 extending rearward is welded to the head 4 of this frame 1, and a pair of left and right frames extending downward. Downtube 4.4 is welded. A pair of left and right seat pillar tubes 5,5 extending downward are welded to the rear of the main frame structure 3, and a seat rail 6.6 is branched rearward from the middle of the seat pillar tube 5.5. .

A seat 7 for the driver A to sit on is installed on the seat rail 6.6, and the seat height is set to be extremely low in the motorcycle of this embodiment.

In addition, the main frame structure 3. down tube 4.4
A V-shaped engine 8 is mounted in the space surrounded by the seat pillar tubes 5 and 5, and this engine 8 is located between the legs B of the driver A. In FIG. 1, 9 indicates a front fork, 10 indicates a handlebar, and 11 indicates a fuel tank.

The engine 8 is supported by the down tubes 4, 4 and the seat pillar tubes 5, 5 through support stays 13, 13f, respectively, at two locations, front and rear, of the crankcase 12. To explain this support structure on the down tube 4 and 4 sides as a representative, as shown in FIGS. The stays 13゜13 are abutted against each other, and each support stay 13゜13 is connected to the down tube 4, 4.
In contrast, it is fixed at two vertically spaced locations via bolts 14, 14 and nuts 15.15ff. Two support protrusions 16, 16 protruding from the front end of the crankcase 12 are interposed between the support stays 13 and 13. It is fixed between the support stays 13.13 by inserting bolts 18.18f installed between the support stays 13.13 and tightening them with nuts 19.19.

The support stay 13.13 is bent to both left and right sides behind the fixed position of the crankcase 12, and this bent end is further extended toward the rear,
The extension portions 20° 20 are located on both sides of the front end of the crankcase 12. Approximately U-shaped brackets 21.21 are fixed on the outer surface of the extension portion 20.20, and left and right footrests 22.22 as leg rests are attached to each bracket 21.21. Footrest 22゜22il of this embodiment: A rubber cover 24 is placed on the outer peripheral surface of a footrest 5 rod 23, and one end of the footrest 5 rod 23 is connected to a bracket 21.21 via pivot pins 25, 251ff. It is pivotably supported rearward and upward. Therefore, the engine 8 and the footrest 22.22 are attached to the frame 1 side via a common support stay 13.13f, and this single support stay 13.13 connects the engine 8 and the footrest 22,
It also has the support function of 22. Further, in this case, the footrests 22, 22 are located further forward than usual, and in combination with the ultra-low seat height, the driver A can take a comfortable riding position with both legs B extended forward.

Note that a shift pedal 26 and a brake pedal 27 are arranged near the footless footless j 2 and 22.

According to such a configuration, the extension part 20 is attached to the support bracket 13.13 that originally supports the front end of the crankcase 12.
．． 20 and the footrest 22.22 was attached to this extension 20.20, so that a single support stay 1
3.13 can also serve as a support function for both the engine 8 and the stress test 22.22. I wanted to,
Since the number of supporting stays and bolts and nuts for their attachment can be reduced, the assembly process can be simplified accordingly, resulting in cost and weight reductions.

Note that the present invention is not limited to the embodiments described above. For example, in the above embodiment, the support stay that supports the front end of the crankcase also has the function of supporting the footrest, but it is also possible to make the support stay that supports the rear part of the crankcase or the middle part of the front and back also have the function of supporting the footrest. Alternatively, the support stay that is originally intended to support the two-restaurant may also have the function of supporting the engine.

Further, the vehicle according to the present invention is not limited to a motorcycle, but can be similarly applied to a tricycle having one steering wheel at the front of the vehicle body and two driving wheels at the rear.

According to the present invention described in detail above, the single support stem provided on the frame can serve both the supporting functions of the two engines and the footrest, so that it is possible to combine the supporting functions of the two engines and the footrest. This has the advantage of being able to reduce costs, simplify the assembly process, and reduce costs and weight.
