Description

[Detailed description of the invention] The present invention relates to a horizontal frame device for a traveling work vehicle, and more specifically, the present invention relates to a horizontal frame device for a traveling work vehicle, and more specifically, for a traveling work vehicle such as a tractor that has horizontal bars long in the traveling direction on both sides of the vehicle body. The frame is used to support the installation of fenders, front loaders, etc. in addition to steps for getting on and off the vehicle.

BACKGROUND ART Some mobile work vehicles, such as wheeled tractors, have long horizontal frames on both sides of the vehicle body in the direction of travel to protect and reinforce the vehicle body, as well as large steps for getting on and off the vehicle for ease of getting on and off.

The present invention utilizes the horizontal frame to attach wheel fenders, which are essential to wheeled tractors, etc., and to attach front working machines such as front loaders.
In a traveling work vehicle that has horizontal frames long in the direction of travel on both sides of the vehicle body, the fender mounting bases fixed at the rear of the horizontal bars are fastened to the rear axle boxes on both sides of the vehicle body, and the horizontal frames are extended forward. In addition, supports provided at the front portion of the horizontal bar are attached to both sides of the vehicle body, and vertical mounting devices are provided at each front portion of the horizontal bar.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings. In FIGS. 1 and 2, 1 is a traveling work vehicle shown as a tractor;
is its front wheel, and 3 is its rear wheel.

Reference numeral 4 denotes an engine, which is mounted near the front of the vehicle body, and a clutch housing 5 and a transmission case 6 are connected to the rear surface of the engine 4 in that order to form a vehicle body 7.

Reference numeral 11 denotes a pair of left and right horizontal frames, each of which has a groove-shaped cross section as shown in FIGS. 4 and 5, and a fender mounting base 12 in the form of an outward opening groove is fixed on the rear upper surface thereof.

The fender mounting base 12 has mounting holes 12A formed diagonally at corresponding positions on its upper and lower surfaces.

Reference numeral 13 indicates a pair of left and right rear axles, and 14 indicates a pair of left and right rear axle boxes, each of which has a rectangular hollow structure extending outward from both sides of the vehicle body 7 by layering the axle 13.

A fender mounting base 12 fixed to the horizontal frame 11 is placed on the upper surface of the rear axle box 14 with the opening of the horizontal frame 11 facing inward,
The rear axle box 14 is sandwiched between the check chain mounting bracket 15 attached to the bottom surface of the rear axle box 14, and the mounting hole 12A is installed.
A bolt 16 is inserted and fastened.

For this fastening, the lower surfaces of the rear wheel fenders 17 are fastened together or independently with fastening bolts 18.

Thus, the lower surface of the rear axle box 14 and the lower surface of the horizontal frame 11 are placed on the same horizontal plane, and the horizontal frame 11 is extended forward while maintaining the horizontal plane, and in this case, the horizontal frame 11 is shown in FIG. Gotoku car body 7
at a predetermined interval from the outer surface of the vehicle body 7, and from the front and rear surfaces of the vehicle body 7 (
(progressing direction), so that even if the clutch housing 5 protrudes here, there will be no problem.

The openings of the horizontal frame 11 are provided with reinforcing plates 11 at predetermined intervals in the longitudinal direction.
A, and on the inside of the front part of the horizontal frame 11 there are 4th and 5th holes.
As shown in the figure, an inverted groove-shaped support 19 is fixed, and inside the support 19, an inward horizontal extension plate 19A is integrally provided.
B via a mounting bolt 19B and fasteners 20A and 20B, and at this time, as shown in FIG.
1 has been condemned.

Reference numeral 22 denotes an vertical mounting fixture, which is fixed to close the front end surfaces of the horizontal frame 11 and the support fixture 19, and has a plurality of mounting holes 22A.
has been established.

Reference numeral 23 denotes a step for getting on and off, and its front inner surface has a shape that follows the outer surface of the clutch housing 5. Correspondingly, the front outer surface is formed into an overhanging part 23A, and the rear part is formed in the gap between the vehicle body 7 and the horizontal frame 11. It extends to the rear so as to block the area.

The front outside inner surface of the getting on/off step 23 is attached to a bracket 24 provided on the horizontal frame 11 with a fastener 27 via a support 26 with a vibration isolating rubber 25 rotatable around a horizontal axis. The inner surface of the front part is attached to the auxiliary stay 28 which protrudes backward from the upper surface of the tool 19 with a bolt (not shown), and the getting on/off step 2
The rear part of the vehicle 3 is supported by the vehicle body 7, the horizontal frame 11, etc.

29 is an auxiliary step, which has a ladder frame structure and has an overhanging portion 23A.
The base extends outward from the outer surface of the frame 11 and is detachable from the horizontal frame 11 with bolts 30.

Furthermore, the lower front portion of the fender 17 mentioned above is attached to the outer surface of the horizontal frame 11 slightly toward the rear of the center using bolts not shown.

In addition, in the figure, reference numeral 31 denotes a cabin having a pair of left and right opening/closing doors 32, which extends from the horizontal plane of the left and right pair of fenders 17 to the front, and further extends to the overhang 23A of the getting on/off step 23, and its lower surface is attached to the front. The vertical support 33 of the section is fastened to the support 26 together with the step 23.

Of course, the cabin is fastened to the fender 17, etc., and is erected to surround the seat and the control device 34 in front of the seat.

Reference numeral 35 denotes a fuel tank, which is supported by gate-shaped supports 37 erected on stays 36 provided on both sides of the clutch housing 5.

Reference numeral 38 designates a front loader, in which a groove-shaped frame 39 with an open front is fixed to a pair of left and right elevation fixtures 22 via fasteners in a detachable manner, and the base of a boom 40 is pivotally supported on this frame 39. 41 are fitted together and can be detached from the side using bolts (not shown).

Furthermore, since the right step of the getting on/off step 23 is equipped with left and right brake pedals 42, differential lock pedal 43, etc., openings 44 etc. for these operating tools are provided, and the left step is provided with an opening 44 for the clutch pedal. A window will be opened.

The configuration of the above embodiment has been described in detail, but in short, the present invention is a traveling working vehicle that has horizontal frames long in the direction of travel on both sides of the vehicle body, and a fender mounting base 12 fixed to the rear of the horizontal frame 11 is attached to the vehicle body 7. The horizontal frame 11 is fastened to the rear axle box 14 on both sides.
are extended forward, and the supports 19 provided at the front of the horizontal frame 11 are attached to both sides of the vehicle body 7, respectively.
Since it is characterized in that vertical mounting fixtures 22 are provided on each front surface of the horizontal frame 11, there are the following advantages.

The mounting bases 12 of the pair of left and right horizontal frames 11 provided with a support 19 at the front and a fender mounting base 12 at the rear are attached to the rear axle box 14.
Since the support 19 is fastened to the vehicle body 7 such as the clutch housing 5 and the horizontal frame 11 is attached to both sides of the vehicle body 7, the horizontal frame 11
serves as a protective member for the vehicle body 7, and can be firmly attached.Furthermore, the step 23 for getting in and out of the vehicle is enlarged, which is advantageous as a frame for a large traveling work vehicle.
Since it is firmly attached to the vehicle body 7, even if the fender 17 is erected on the mounting base 12 at the rear, or a heavy work machine such as a front loader 38 is mounted on the front elevation mount 19, it will not work. There is an advantage that these can be supported in a strong and stable manner.
