Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to the structure of a mounting part for operating pedals and the like that utilizes a front plate that partitions the front part of the cockpit and the rear part of the engine of a traveling vehicle.

[Prior Art] In a traveling vehicle such as a riding tractor, the cockpit is installed as a separate frame at the top of the vehicle body that integrates the engine, transmission case, etc., and operates the operating pedals such as the brake pedal and clutch pedal. was attached to the frame on the cockpit side. For example, in the device shown in FIGS. 1 and 2 of JP-A No. 57-22919, the pedal 4 is attached to the floor 9 that constitutes the frame of the cockpit or the front wall 2 that is integrated with the floor 9. In the one shown in Japanese Patent Application Laid-open No. 59-227524, the device is suspended near a dart board fixed to the frame of the cockpit.

[Problems to be solved by the invention] In the conventional vehicle described above, the operating pedals, etc. were attached to the frame of the cockpit, so when assembling or disassembling the cockpit, the operating pedals, etc. had to be assembled or removed at the same time. These tasks were difficult because of the need to do so. Particularly, when the floor part is supported by a spring or the like in a vibration-proof manner, there is a problem in that the pedals vibrate due to vibrations in the cockpit during operation, producing noise. Furthermore, if the operating system is hydraulic, it is necessary to connect the operating pedal and the transmission case side with a rod.
Since the control pedals vibrate due to vibrations from the cockpit, it was difficult to connect them with rods.

[Means for Solving the Problems] In order to solve the above problems, the present invention has the following configuration. That is, the structure of the mounting part for the operation pedal etc. according to the present invention includes a front plate that partitions the cockpit of the vehicle and the rear part of the engine, a plate mounting bracket fixed to the engine side,
The present invention is characterized in that it is fixedly sandwiched between the plate mounting bracket and a pedal mounting bracket, and an operating pedal or the like is attached to the pedal mounting bracket.

[Function] A front plate that partitions the rear of the engine is held between a plate mounting bracket fixed to the engine side and a pedal mounting bracket fixed to the bracket, and an operating pedal is attached to this pedal mounting bracket. As a result, although the operating pedal is installed inside the cockpit, it is supported independently from the frame of the cockpit, which makes assembly and disassembly of the cockpit easy, and vibrations in the cockpit are suppressed by the pedals. It is not conveyed to others.

[Examples] Examples shown in the drawings will be described below.

In the tractor 1 shown in FIG. 1, an engine 2 and a transmission case 3 forming a vehicle body are integrally joined at the front and rear, and a final drive device 5 is provided at a rear wheel shaft 4. Further, a box-shaped cabin 10 constituting a cockpit is provided behind the engine 2 and above the transmission case 3 and the final drive device 5. The cabin 10 includes a roof part 11 supported by support pillars, a floor part 13 supported by the vehicle body by a vibration-proof structure made of springs 12, 12, and a front plate 14 that partitions the rear of the engine 2 from the cockpit. , a side wall portion 15, and a door 16 that can be opened and closed. cabin 10
A cockpit 17, a steering wheel 18, an instrument panel 20, various operation pedals, etc. are provided inside the vehicle.

The upper part of the engine plate 29 provided at the connection between the engine 2 and the transmission case is
An upwardly projecting plate mounting bracket 31 is fixed by bolts 30, .... A pedal mounting bracket 32, etc. is fixed to the upper end of this plate mounting bracket 31 via the front plate 14 by bolts 33, .... In other words, the front plate 14 is sandwiched between the plate mounting bracket 31 and the pedal mounting bracket 32.
0 is attached to the pedal mounting bracket 3 by the legs 26
It is attached to 2.

The handle 18 of the tractor 1 is a tilt handle, and is provided on the instrument panel 20 so that its mounting angle can be adjusted. A rod 21 connected to the base of the steering shaft 18a is connected to a pitman arm of a front wheel 22.

The brake pedal 25 is
It is rotatably attached to a pedal-mounting bracket 32 by a shaft 25a provided at the base of the pedal. Further, the clutch pedal, which is not shown in FIGS. 1 and 2, is also attached to the pedal-mounting bracket 32 in the same way as the brake pedal 25. Both upper and lower ends of the front plate 14 are connected to the transverse frame 35 of the cabin 10 and the front end of the floor section 13, respectively, via boots 34, 34' made of an elastic material. This front plate 14 prevents dust and engine 2
This prevents hot air from entering the cockpit.

An arm 37 is provided on the brake shaft 25a, and one end of a connecting rod 38 is attached to the tip of the arm 37. Further, an arm 39 is rotatably supported on the mission case 3, and the other end of a connecting rod 38 is attached to the intermediate portion of the arm 39. Furthermore, arm 39
A brake rod 40 is attached to the tip. Depressing force applied to the brake pedal 25 is transmitted to a brake device 42 provided on the rear wheel axle via the connecting rod 38, brake rod 40, and the like.

FIG. 3 shows an example different from the above, in which the tractor 1' is not provided with a cabin,
The cockpit 10' is roofless. This tractor 1' is also provided with a front plate 14 similar to the previous example, and pedals are attached to this. That is, the illustrated clutch pedal 45 is rotatably attached to the pedal-mounting bracket 32 by a shaft 45a provided at the base of the clutch pedal 45. An arm 46 provided on this pedal
The pedal 4 is connected by a connecting rod 47 attached to the pedal 4.
The force applied to the transmission case 5 is transmitted to the clutch shifter 48 inside the transmission case 4.

Further, 50 in FIG. 2 is a tilt pedal for adjusting the angle of the tilt pedal, and is attached to a bracket 51 fixedly provided on the front plate 14.

In this way, the front plate 14 of the tractor 1, 1' is provided separately from the other members constituting the cockpit 10, 10', and has a plate mounting bracket 31 and a pedal etc. mounting bracket 32.
Since the structure is such that it is fixed to the engine side (vehicle body side) by being sandwiched between the two, assembly of the cockpit is easy. In the illustrated tractors 1 and 1', both upper and lower ends of the front plate 14 are connected to the cockpit via boots 35 and 35' made of elastic material, respectively, so that these parts can be kept airtight. In both cases, the vibration from the cockpit causes brake pedal 2.
5. The structure is such that the signal is not transmitted to the clutch pedal 45, etc.

When removing the cabin 10 from the vehicle body, the bolts 31 that attach the front plate 14 can be removed.

[Effects of the invention] As is clear from the above explanation, the structure of the mounting part for the operation pedals, etc. according to the present invention is such that the mounting bracket for the pedals, etc. is mounted on the vehicle body side, not on the cockpit side. Vibrations in the cockpit are not transmitted to the pedals, and the cockpit can be easily disassembled and reassembled. Furthermore, since the tilt pedal, brake pedal, clutch pedal, etc. are provided independently of the cockpit, this is advantageous in terms of compatibility between models with different cockpit specifications.
