Description

[Detailed description of the invention] This invention prevents contact between the front wheels of the dolly and the front frame of the trailer by narrowing the width of the front frame rotatably connected by a king pin, and prevents the front frame of the trailer from contacting the front frame of the trailer. This relates to a full trailer designed to lower the height above the ground.

Conventionally used full trailers had the drawback that the entire frame was parallel, so when the front wheels of the dolly rotated around the kingpin, the front wheels came into contact with the front frame of the trailer. .

In order to eliminate these drawbacks, the height of the front frame above the ground is one step higher than that of the front wheels, thereby preventing the front wheels from coming into contact with the parallel frame when the front wheels rotate. Was. However, generally speaking, increasing the ground height of the frame raises the center of gravity of the vehicle, which impairs vehicle running and brake stability, and increases the labor required for loading and unloading operations, which increases mechanical work. In this case, there were disadvantages such as increased power.

Therefore, the present invention was devised to eliminate the above-mentioned drawbacks, and aims to improve vehicle running and brake stability, and to reduce labor and power required for various cargo handling operations.

The present invention is based on a full trailer in which the front frame 3 of front and rear frames 3, 5 consisting of a front frame 3 and a rear frame 5 is rotatably connected to a dolly 6 by a king pin 1, and the front wheels are attached to the rear of the dolly 6. 2 is provided, and the front frame 3 is rotatably pivoted to the dolly 6 by a king pin 1 at a substantially center position in the width direction of the dolly 6 between the two front wheels 2, 2, and is provided at the rear of the front frame 3. It is narrower than the width of a certain rear frame 5, and its width is formed to a dimension width that does not come into contact with the front wheels 2, 2 when the front wheels 2, 2 bend and rotate, and the front wheels 2, 2 and the rear wheels 4, Dolly 6 and front and rear frames 3 and 5 respectively supported by
This is a full trailer characterized in that the height H above the ground at the supporting position of the trailer is lower than the height H' above the ground of a conventional trailer.

To explain in more detail based on one embodiment of the drawings, FIGS. 1 and 2 relate to a full trailer according to the present invention, and as shown in FIG. The conventional full trailer shown in FIG. , the width of the front frame part 3' and the rear frame 5 are the same, and the height above the ground H' is,
It is higher than the ground height H compared to the frame of the present invention shown in FIG.

Since the present invention is constructed as described above, even if the front wheel 2 of the full trailer rotates around the kingpin 1, there is no risk of the front frame 3 and the front wheel 2 coming into contact with each other. The ground height H' of the frame 3' and the rear frame 5 is set to the above ground height H.
It becomes possible to attach the front frame 3 and the rear frame 5 to a lower position as shown in FIG. Therefore, according to the present invention, the ground height of the frame can be lowered than before, which not only lowers the center of gravity of the entire vehicle and improves running stability, but also improves loading and It has the effect of reducing labor and time during unloading work, and can also be expected to save energy consumed for motive power.
