Description

locomotive

The present invention relates to a locomotive, in particular to a locomotive that facilitates maintenance.

When designing the body shape of the locomotive and the placement of the components, one of the key considerations is to respond to the maintenance needs, especially for some that require a short period of regular maintenance, or the configuration is relatively internal and other components must be disassembled for maintenance. The target components will even be specially equipped with exclusive maintenance mechanisms in order to improve the efficiency and convenience of maintenance.

Among them, for vehicles equipped with fixed engines, since there is no need to reserve room for the swing of the engine, and there is no need to consider whether the engine may hit the ground when it swings, the engine is placed in a relatively low position, which makes the maintenance cycle Shorter cylinder heads and fuel pumps are all located at a lower position. According to traditional maintenance methods, many components must be disassembled from top to bottom to perform maintenance, which is quite inconvenient and causes low maintenance efficiency.

[Problems to be solved by the present invention]

Therefore, the object of the present invention is to provide a locomotive that is easy to repair the cylinder head and fuel pump of the engine.

[Technical means to solve the problem]

The locomotive of the present invention includes a central cover, an engine arranged under the central cover, a fuel pump connected to the engine, a foot pedal arranged above the fuel pump and located in front of the engine, and a detachable ground A maintenance cover connected between the central cover and the foot pedal. The engine includes a front-facing cylinder head, and the cylinder head has a plurality of locking bolts. The pedal includes a structural part defining a first opening and a second opening, and two pedaling parts respectively connected to opposite sides of the structural part. The first opening faces the fuel pump, and the second opening faces at least one position lower than the locking bolt of the structural part. The maintenance cover includes a first shielding portion that covers the structural portion of the pedal and is used to shield the first opening and the second opening, and a first shielding portion that is bent from the first shielding portion and used for The second shielding part that shields the cylinder head of the engine.

In some embodiments of the present invention, the structure portion of the footrest has a first surrounding wall that completely surrounds the first opening, and a second surrounding wall that completely surrounds the second opening.

In some embodiments of the present invention, the cylinder head of the engine further has an oil port that is higher than the foot pedal and is shielded by the second shielding portion of the maintenance cover.

In some embodiments of the present invention, the first shielding portion and the second shielding portion of the repair cover are integrally formed.

In some embodiments of the present invention, the locomotive further includes a seat cushion arranged above the central cover.

In some embodiments of the present invention, the engine is a fixed configuration without swinging.

[Effects Achieved by the Invention]

When it is necessary to repair the cylinder head or the fuel pump of the engine, simply remove the repair cover, and the fuel pump can be repaired through the first opening of the pedal, or the fuel pump can be repaired through the second opening. The cylinder head of the engine not only does not need to disassemble other components to make maintenance more convenient, but also greatly improves the efficiency of maintenance.

In some embodiments of the present invention, the first opening and the second opening completely surrounded by the first surrounding wall and the second surrounding wall are closed openings, thereby ensuring the rigidity of the structure , So that the foot pedal is sufficient to perform a stable pedaling function.

In some embodiments of the present invention, as long as the maintenance cover is removed, the oil port of the cylinder head can be exposed to the outside, which is easy to change the oil for regular maintenance.

In some embodiments of the present invention, there is no need to disassemble the seat cushion or the center cover. As long as the maintenance cover is disassembled in a single disassembly step, the cylinder head and the fuel pump can be repaired at the same time.

1 is an embodiment of the locomotive of the present invention. This embodiment includes a central cover 1, an engine arranged under the central cover 1, a fuel pump 3 connected to the engine 2, and a fuel pump 3 arranged on the fuel A foot pedal 4 above the pump 3 and in front of the engine 2, a maintenance cover 5 detachably connected between the central cover 1 and the foot pedal 4, and a seat cushion 6 arranged above the central cover 1 . It should be noted that the engine 2 in this embodiment is a fixed configuration, so it cannot be oscillated and fixed, so it can be placed in a lower position, which is beneficial to reduce the weight of the engine 2 The overall center of gravity of the embodiment is to improve driving stability, but the present invention is not limited to the engine 2 in a fixed configuration.

The engine 2 includes a cylinder head 21 facing forward. The cylinder head 21 has a plurality of bolts 211 and an oil port 212 higher than the pedal 4. Wherein, the height positions of the locking bolts 211 are different, and when performing maintenance of various parts of the cylinder head 21, it is necessary to work on the corresponding locking bolts 211. As shown in FIG. 1, two of the locking bolts 211 located at the front can be seen, and as shown in FIG. 2, there is another locking bolt 211 located at a lower position than the pedal 4.

Referring to FIGS. 1 to 3 at the same time, the pedal 4 includes a structural portion 41 that defines a first opening 401 and a second opening 402, and two pedaling portions respectively connected to opposite sides of the structural portion 41 412. The structure portion 41 has a first surrounding wall 411 completely surrounding the first opening 401 and a second surrounding wall 412 completely surrounding the second opening 402. Due to the basic function of pedal 4 for pedaling, a certain degree of rigidity must be ensured. With the first surrounding wall 411 and the second surrounding wall 412, which are approximately elliptical, the first surrounding wall 411 and the second surrounding wall 412 can be reliably surrounded. In the case of the opening 401 and the second opening 402, it is avoided that the opening has a gap and the rigidity sufficient for pedaling is not affected. Wherein, the first opening 401 faces the fuel pump 3, and the second opening 402 faces the locking bolt 211 which is lower than the structure portion 41 of the pedal 4 as described above.

The maintenance cover 5 includes a first shielding portion 51 covering the structural portion 41 of the footrest 4 and used for shielding the first opening 401 and the second opening 402, and a self-shielding The portion 51 is integrally bent and used to shield the second shielding portion 52 of the cylinder head 21 of the engine 2. Wherein, the first shielding portion 51 and the second shielding portion 52 are integrally formed, so that the first shielding portion that shields the first opening 401 and the second opening 402 can be shielded at the same time in a single disassembly step 51, and the second shielding portion 52 that shields the cylinder head 21 are disassembled together, thereby simplifying the disassembly steps during maintenance, and avoiding the maintenance efficiency and work time being affected by the successive disassembly of multiple shells.

Referring to Fig. 4 and in conjunction with Fig. 1, when it is necessary to perform maintenance on the cylinder head 21 or the fuel pump 3 of the engine 2, only the maintenance cover 5 needs to be disassembled, that is, the cylinder head 21 can be opened to the outside, in addition to convenience In addition to replenishing the oil from the oil port 212, there is also enough working space to perform maintenance on the cylinder head 21. In addition, the first opening 401 and the second opening 402 originally shielded by the first shielding portion 51 can be used by maintenance personnel to repair the fuel disposed under the foot pedal 4 through the first opening 401. Pump 3, also because of the configuration of the cylinder head 2, a part is located lower than the foot pedal 4, so it needs to pass through the second opening 402 to respond to the lock which is lower than the foot pedal 4. The bolt 211 is used to facilitate the lower configuration of the engine 2.

In addition, it should be particularly emphasized that since the repair cover 5 specifically covers the longitudinal range that shields the cylinder head 2 and the lateral range extending to the foot pedal 4, compared to removing a smaller cover, After disassembly, the maintenance cover 5 will reveal a relatively large opening, and the opening allows the operator to have a larger working space no matter when performing maintenance on the cylinder head 2 or the fuel pump 3, It is helpful to improve the efficiency of maintenance work.

To sum up, in this embodiment of the locomotive of the present invention, when the cylinder head 21 or the fuel pump 3 needs to be repaired, there is no need to start the disassembly of the seat cushion 6 as in the prior art, as long as the repair is directly disassembled in a single step. The cover 5 can expose the cylinder head 21 to the outside for easy maintenance, and the fuel pump 3 can be repaired through the first opening 401, or the cylinder head 21 can be repaired below the pedal through the second opening 402. The part of the board 4 not only does not need to disassemble other components to make maintenance more convenient, but also greatly improves the efficiency of maintenance. Therefore, the purpose of the invention can indeed be achieved.

However, the above are only examples of the present invention, and should not be used to limit the scope of implementation of the present invention, all simple equivalent changes and modifications made in accordance with the scope of the patent application of the present invention and the content of the patent specification still belong to This invention patent covers the scope.
