Description

[Detailed Description of the Invention] This invention relates to a swinging connection mechanism between a traveling body and a transporting body in a power transport vehicle.

Conventionally, in power transport vehicles, a pivot shaft fixed to the fuselage frame is rotatably attached to approximately the center of the differential case that rotates the traveling wheels, so that the vehicle can be easily rotated when traveling on uneven roads. The structure is such that only the running wheels absorb the rotation from side to side based on the pivot shaft of the fuselage frame, and the structure of the differential case is complicated, and it is difficult to assemble the pivot shaft and the differential case, making inspection difficult. However, it also had the disadvantage that it required a lot of man-hours to repair, etc., and was likely to cause malfunctions.

In this design, the power transport vehicle has a traveling body section equipped with an engine, a driver's seat, etc., and a transporting body section on which cargo is placed, which are formed independently. The two bodies are connected to each other in a swingable and removable manner, and the joint between the two bodies absorbs changes in direction of the body and vibrations that occur in the body on uneven roads or in the workplace. It is an object of the present invention to provide a rocking connection mechanism between a traveling body and a transporting body in a power transport vehicle, which is configured to swing the traveling body or the transporting body independently. .

An example of this invention will be explained in detail based on the drawings.
The power transport vehicle 1 consists of a traveling machine body part 2 and a transporting machine body part 3, and a coupling mechanism part 4 is provided at the rear end of the traveling machine body part 2 and the front end of the transporting machine body part 3.

The traveling body part 2 is provided with a steering wheel 5 at the upper end of the base frame 12,
An engine 7 is mounted on the other side and surrounded by a bonnet 8, and a front wheel 9 is mounted below the base frame 12.
is installed. The front wheels 9 are pivotally supported on both sides of a front differential case 10 which is suspended and fixed to a base 13 fixed to a base frame 12.
The power of an engine 7 is transmitted to a transmission case 11 integrally connected to a front differential case 10 to change gears, and the power is transmitted to the front differential case 10 to rotate front wheels 9.

The transport body section 3 has a rear wheel 16 and a rear wheel 17 pivoted on the outside of a support frame 15 which also serves as a chain case 14 and is disposed substantially parallel to the front wheels 9. A bracket 18 is fixed to the rear end of the support frame 15, one end of a loading platform 19 is pivotally connected 20, and a hydraulic pressure is connected to the lower end of the loading platform 19. One end of a cylinder (not shown) is pivotally connected to rotate the loading platform 19 in the vertical direction.

The coupling mechanism section 4 includes a hollow shaft 2 that is fixed at one end to the lower part of a bracket 22 that extends downward from the rear center of the base 13 of the traveling machine body section 2 and extends toward the rear of the machine body.
3 and both chain cases 14, 14 of the transport body part 3.
Loading platform frame 24 that is horizontally fixed to the front upper part of the
and a boss 26 fixed to the center of the auxiliary frame 25. The hollow shaft 23 is loosely fitted into the boss 26 and protrudes, and a locking ring 27 is attached to the protrusion by the bolt 2.
It is fixed at 8.

The upper edge of the bracket 22 is fixed to the horizontal frames 29, 30 at the bottom of the base 13, and is open at the surface of the base 13, forming a space 31 in which tools and the like can be stored. On the other hand, an opening 32 is provided in the front of the lower part of this bracket 22, and an insertion hole 33 is provided in the rear, and the hollow shaft 23 is inserted into the insertion hole 33.
It is inserted and stuck.

Further, the upper part of this insertion hole 33 is provided with the traveling body part 2.
and the V-shaped locking plate 34 for mutual rocking of the transport body part 3.
The locking plate 34 is engaged with an engaging plate 35 that protrudes and is fixed to an auxiliary frame 25 horizontally suspended in front of the transport body 3.

The embodiment of this invention is constructed as described above, and the power of the engine 7 is supplied to the transmission case 11.
One part is transmitted to the front wheels 9 via the front differential case 10, and the other part is transmitted to the rear differential case 36 via the transmission case 11, universal joint 6, and propeller shaft 6'.
The transmission is transmitted to the rear wheels 16, 16 via the final gear case 37, and the gear of the final gear case 37 of the rear wheel 16 and the rear wheel 1 are rotated.
The front wheel 9, the rear wheel 16, and the last wheel 17 are connected to the engine 7 by connecting the gears in the final gear case (not shown) of 7 with a chain passing through the chain case 14 and rotating the last wheel 17. The front wheels are driven at the same time.

Moreover, the power carrier 1 of this invention has a traveling body part 2.
and the transporting machine body part 3 are connected by a connecting mechanism part 4, and when traveling, the traveling machine body part 2 and the transporting machine body part 3 can mutually swing left and right about a hollow shaft 23 ( (indicated by arrow).

That is, the hollow shaft 23 fixed to the traveling machine body part 2 is loosely fitted into the boss 26 fixed to the transport machine body part 3, and the rear end of the hollow shaft 23 is made to protrude from the boss 26,
Since the locking ring 27 is fixed to this protrusion, the hollow shaft 23 can slide along the inner circumferential wall of the boss 26 around the core axis of the hollow shaft 23, so that it can freely swing left and right. .

Furthermore, as described above, the hollow shaft 23 and the boss 2
6 is rotatably locked by the locking ring 27, and the fixing bolt 2 of the locking ring 27
8 and extracting the locking ring 27 from the hollow shaft 23, the traveling machine body part 2 and the transport machine body part 3 can be separated. Furthermore, the hollow shaft of the connecting mechanism provided in the traveling body part is
It is easy to install as it is guided by the boss on the transport body, and since the boss loosely fits around the hollow part, it protects the hollow shaft and prevents the intrusion of dirt, etc. , swings smoothly.

In addition, since the hollow shaft and boss are attached to the lower part of the aircraft, the hollow shaft swings smoothly without wobbling when traveling on uneven and steep roads, improving the stability of the aircraft. ing.

According to this invention, by means of a hollow shaft and a boss attached to the connecting part between the traveling body part and the transport body part of a multi-wheeled power transport vehicle, both body parts are formed to be able to swing freely relative to each other, and the body part By freely absorbing the lateral vibration that occurs during running, and by forming the hollow shaft and boss into a removably connected state, it is easy to assemble, disassemble, preventive maintenance, repair, etc. of power carriers. The time is shortened, and even when the machine moves in a highly uneven work area, the hollow shaft and boss allow it to swing independently. This has prevented malfunctions from occurring, and the stable running has made it possible to work more comfortably. Furthermore, the hollow shaft of the traveling body part is guided by the boss of the transporting body part, so that it can be easily mounted.

Furthermore, since the hollow shaft is covered with a boss, it prevents the intrusion of earth and sand, allows for smooth rocking motion, and allows for running along uneven surfaces.

Moreover, since the hollow shaft and boss are located low on the aircraft, there is no wobbling of the hollow shaft when driving.
It swings smoothly and runs stably.
