PURPOSE:To simplify the structure of a fuel supply part in a power vehicle. CONSTITUTION:A fuel tank 20 is installed near an engine 2 provided with an injection pump 22, while a bracket 28 is installed in a spacing part between the fuel tank and the injection pump free of detachment at a side part of the engine, and a fuel pump 23 feeding the injection pump with fuel from the fuel tank and a fuel filter for eliminating dust in the fuel both are attached to this bracket.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the arrangement and attachment of items stored in the bonnet of a power vehicle such as a tractor.

0002

[Prior Art] A tractor with an engine mounted on the front of the machine has the engine, fuel tank, fuel pump, fuel filter, etc. housed inside the bonnet.
These items were scattered and arranged.

0003

[Problems to be Solved by the Invention] Therefore, the fuel hose that connects the stored items becomes longer than necessary, and there is a high risk of the fuel hose being damaged, and furthermore, the long fuel hose becomes a hindrance to other equipment. There was a problem that it was difficult to carry out repairs and inspections.

0004

[Means for Solving the Problems] In order to solve the above problems, the present invention has the following configuration. That is, in the power vehicle according to the present invention, a fuel tank is provided near the engine to which the injection pump is attached, and a bracket is detachably provided in the space between the fuel tank and the injection pump on the side of the engine. The fuel pump is equipped with a fuel pump that sends fuel from the fuel tank to the injection pump, and a fuel filter that removes dust from the fuel.

[0005]

[Operation] The fuel supply-related equipment, such as the fuel tank, fuel pump, fuel filter, and injection pump, are arranged in order along the direction of fuel flow, so they can be stored compactly under the hood. At the same time, the hose connecting these can be shortened. Furthermore, since the fuel pump and fuel filter are attached to a bracket that is detachably provided on the side of the engine, the bracket can be attached and detached together, making assembly, repair, and inspection easy.

[Embodiment] Fig. 3 is a side view of a tractor that is an embodiment of the present invention.This tractor 1 has an engine 2 mounted on the front part of the body, and a clutch case 3 integrally provided on the rear part. Further, a mission case 4 is provided behind it. The front wheels 7 are mounted on the front axle housings 6, 6 provided diagonally below the front of the engine 2 when viewed from the side.
, 7 are pivotally supported so as to be able to change direction, and left and right rear wheels 9, 9 are attached to rear axles 8, 8 which protrude laterally from the transmission case 4. clutch case 3
Transmission is transmitted from the inner clutch 3a to the transmission case 4 via the universal joint 11, and from the transmission case 4 to the front axle housing 6 via the front wheel transmission shaft 12. A cockpit 14 is installed above the mission case 4, and a steering wheel 15 is attached in front of the cockpit. The upper part of the front part of the steering wheel 15 is covered by a bonnet 16, and in addition to the engine 2, a radiator 18, a battery 19, a fuel tank 20, etc. are housed under the bonnet.

FIGS. 1 and 2 show the inside right rear corner of the bonnet 16. FIG. Engine 2 of this tractor 1
is a diesel engine, and injection pumps 22, . . . are attached to the right side of the engine. Fuel is sent from the fuel tank 20 to the injection pumps 22, . . . by a fuel pump 23. fuel tank 20
A line filter 24 is provided in the pipe connecting the fuel pump 23 and the fuel pump 23, and a main filter 25 is provided in the pipe connecting the fuel pump 23 and the injection pump 22. Both filters 24 and 25 are for removing impurities from the fuel. These fuel pump 23, line filter 24, and main filter 25 are attached to a bracket 28 that is detachably attached to the side surface of the engine 2 with bolts 27, . . . . This bracket 28 is assembled on the same side (right side) as the side where the injection pumps 22, . For this reason, the above devices 23, 24, 2
5 is a fuel tank 20 and an injection pump 22,...
It is functionally and compactly stored in the space between. Moreover, each pipe 29 (a, b, c, d) is shortened accordingly.

As in this embodiment, the radiator 1 is installed from the front.
8. If the engine 2 and the fuel tank 20 are arranged in this order, the fuel tank 20 is likely to be affected by the heat of the engine 2. In order to protect the fuel tank 20 from this heat, the front part of the fuel tank 20 is covered with a heat insulating material 31 made of glass wool. This heat insulating material 31 is attached to the rib 20b of the fuel tank, and is fixed by a resin refueling monoguard receiving tray 32 so as not to fall off forward.

FIG. 4 shows a different embodiment. In this tractor 1', a fuel filter 36 is attached to the lower side of a battery bracket 35 to which a battery 19 is attached. In this way, by providing the fuel filter 36 at the front end of the aircraft body, the cooling efficiency of the fuel filter 36 is improved.
Engine output increases. Furthermore, since the mounting position of the fuel filter 36 is lowered, air can be easily removed even when there is little fuel. Furthermore, fuel filter 3
Since fuel filter 6 is surrounded by bumper 37 and battery bracket 35, there is also the advantage that fuel filter 36 is well protected.

0010

Effects of the Invention As explained above, in the power vehicle according to the present invention, the fuel pump and the fuel filter are attached to a common bracket, and this bracket is assembled together with the side part of the engine. In addition to being able to store equipment compactly, maintenance can now be performed easily.
