Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tricycle in which a front body on the side of one front wheel swings left and right with respect to a rear body on the side of two rear wheels.

The applicant previously provided a small-sized motor tricycle that is approximately equivalent to a motorcycle, which has one front wheel and two rear wheels, and the front body of the front single wheel swings from side to side with respect to the rear body of the two rear wheels. .

In the above tricycle, when a loading platform is provided at the rear of the swinging vehicle body, the width of the low floor and the rear part is different, and if the width of the rear part is large, the rear part protrudes to the side, making it difficult to drive. It is common sense for passengers to keep in mind the width of the front floor when driving, so always keep in mind that there will be inconveniences such as passing through, and that there is a width that is greater than the width of the floor when driving. It is difficult to drive because it is necessary to do this.Furthermore, if leg shields, etc. are installed on the front part, or left and right turn signals are installed in addition to the above, if these protrude from other parts, the same problem as above will occur. There is a risk that this will be accompanied by

The present invention has been made to improve the above-mentioned problems, and its purpose is to provide a front vehicle body comprising a front vehicle body equipped with one steering wheel and a rear vehicle body equipped with two driving wheels. It is a rocking type automatic tricycle that is connected to the vehicle body so that it can swing from side to side.It allows heavy objects to be loaded behind the seat at the rear of the front body, making it easier to drive through, etc., and protecting the occupants from wind and rain. To provide a rocking type automatic tricycle which can also secure sufficient space under the roof by using a loading platform when a roof is provided to protect the vehicle from damage.

Next, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows a side view of the tricycle, and FIG. 2 shows a plan view thereof.

The tricycle 1 supports a front fork 4 that supports a front wheel 5 in a freely steerable manner via a head tube 3 at the front end of a frame 2, and has a steering stem 6 connected to the upper end of the front fork 4 and provided with a handle 7 at the upper end. A cover 9 is provided in the center of the handle 7 and serves as a cover for the meter unit 8 and a cover for the headlight unit.

The frame 2 described above includes a down frame 2a that tilts rearward and downward from the head pipe 3, a substantially horizontal lower frame 2b that extends rearward from the rear end of the down frame 2a, a center frame 2c that also serves as a seat post and stands upward from the rear end of the down frame 2a. It consists of a seat frame 2d extending rearward from its upper end. A joint 10 is provided under the rear of the lower frame 2b, and a support shaft 11 is provided.
The power unit 1 forms the rear vehicle body B behind the center frame 2c and below the seat frame 2d.
Power unit 1
Two rear wheels 13, 13 forming drive wheels are arranged on both sides of the wheel. The rear wheel 1 is mounted on the top of the power unit 12.
A cover 14 that also serves as fenders 3 and 13 is provided.

A front cover 15 surrounding the steering stem 6 is provided between the head pipe and the cover 9 at the center of the steering wheel, and the cover 15 is provided with leg seal parts 16, 16 on the left and right that project to the left and right. Down frame 2a from the bottom of the cover 15
An undercover 17 is provided to cover the top, and a footrest floor 1 is provided which forms a low floor from the rear end of the undercover 17.
8 is extended, and the floor 18 covers the lower part 2c. At the rear of the floor 18 there is a seat post cover 1 above.
9 is protruded, and the seat post cover 19 is on the floor 1.
A rear cover 20 is provided diagonally rearward and upward from the rear end of the floor 18, which is smaller than the width of the floor 18 and has a seat post cover 19 provided in the intermediate part, and from the upper end of the rear cover 20. A loading platform 21 is extended to the rear, and the loading platform 21 is provided above the rear end of the rear wheel 13, and a seat 22 is provided on the seat post cover 19.

The width of the floor 18 described above is approximately the same as the width between the rear wheels 13, 13, and the width of the floor 18 and the rear cover 20 are
and the width of the rear loading platform 21 are approximately the same,
Furthermore, the width of the left and right leg shields 16, 16 forming the front cover 15 is also approximately equal to the width of the floor 18. Therefore, the front cover 15, the undercover 17, the floor 18, the rear cover 20, and the loading platform 2
1 is formed to have approximately the same width, preferably the same width, from the front end to the rear end.

By the way, handle covers 23, 23 are provided on the left and right sides of the cover 9 at the center of the handle, and for example, left and right front blinkers 24, 24, and the front turn signals 24, 24 are thus arranged within the width of the floor 18. Then, on the rear end wall 21a of the loading platform 21, there are rear turn signals 2 on the left and right.
5, 25 are provided, and a tail light 26 is provided in the center.
is provided. In this way, rear blinker 25,
25 will be arranged within the width of the floor 18.

Next, to explain its function and effect in detail, the front body that swings from side to side has approximately the same width from the front end to the rear end, and therefore, when driving or driving, the front width and the rear width are approximately the same. There is no need to keep in mind that the front and rear widths are different, and since the front and rear are the same width, you can drive comfortably and without worrying about the width. This allows you to drive through the vehicle without unconsciously considering the width of the floor area and without considering your surroundings, and you can drive with the same feeling as driving a motorcycle. The rear cargo bed swings together with the floor, so unlike a non-swingable cargo bed on the rear body of the vehicle, you can pass through it by feeling the width of the floor. In this way, a comfortable driving feeling can be obtained, and since the tricycle has a loading platform, the practicality of this type of tricycle can also be improved.

As described above, according to the present invention, the vehicle is comprised of a front vehicle body equipped with one steering wheel and a rear vehicle body equipped with two driving wheels, and the front vehicle body is connected to the rear vehicle body so as to be swingable from side to side. In a rocking motor tricycle made up of
A loading platform is provided behind the seat at the rear of the front vehicle body and extends from above the two driving wheels provided in the rear vehicle body to near the rear end, and the width of this loading platform is a wide shape that is approximately equal to the width of the two driving wheels. This makes it possible to load heavy items behind the seats at the rear of the front vehicle body, and as mentioned above, it makes it easier to drive through, etc., and the cargo platform is made wider than the drive wheels of the two wheels. In comparison, even when the drive wheels approach the curb, the loading platform is less likely to come into contact with the guardrail.

In addition, when cargo is unevenly distributed on the cargo bed, the center of gravity of the front vehicle shifts, but by moving the feet of the occupants placed on the floor, which is approximately the same width as the cargo bed, to the side, the sensation of driving when cornering can be improved. It is also possible to eliminate changes in .

In the above rocking tricycle, if you want to equip the vehicle body with a roof to protect the occupants from wind and rain, attach the front end of the roof to the leg shield,
By passing above the passenger and attaching the rear end onto the cargo platform, sufficient space can be secured under the roof.

The present invention has many advantages as described above.
