Description

[Detailed Description of the Invention] Technical Field The present invention relates to industrial vehicles such as forklifts and shovel loaders, and particularly to support structures for air cleaners in engine-powered vehicles.

Prior Art In general, when installing an air cleaner in the engine room, the air cleaner element must be easy to replace, serviceability within the engine room should not be hindered, piping resistance should be small, and the cost of installation parts should be low. The following conditions are required. FIG. 4 shows a support structure for an air cleaner in a conventional forklift. The air cleaner 30 is disposed on the side of the engine 31 so that its axial direction is parallel to the longitudinal direction of the vehicle, and is attached to a side frame 32. It is attached via a cleaner bracket 33. However, with such a support structure, when the air cleaner 30 is brought closer to the engine side in order to reduce piping resistance by shortening the cleaner hose 34, the serviceability of the engine deteriorates, and conversely, the engine 31
Although servicing can be improved when the cleaner hose 34 is moved away from the vehicle body, the extension of the cleaner hose 34 results in an increase in piping resistance, making it impossible to satisfy either of the conditions. When performing service work, there are drawbacks such as the troublesome task of replacing the cleaner element because the direction in which the cleaner element goes in and out and the direction in which the cover 35 is attached and removed are oriented sideways to the operator.

Purpose of the invention The purpose of the present invention is to provide a support structure for an air cleaner in an industrial vehicle that can eliminate the above-mentioned conventional drawbacks and meet the various conditions described above when installing an air cleaner in an engine compartment. Our goal is to provide the following.

Composition of the Invention In the present invention, an air cleaner is arranged above the engine so that its axial direction is parallel to the vehicle width direction, and the air cleaner is arranged to extend between the front and rear frames of the engine room for attachment to the engine hood. It is suspended from the bottom of the stay.

Embodiment This embodiment is aimed at a forklift, and 1 in the figure shows an engine room formed almost in the center of the vehicle body 2. The upper part of the engine room 1 has its front surface on the side frame 3 of the vehicle body. The rear surface is covered by a front frame 4 fixed to the side frame 3, the rear surface is covered by a substantially U-shaped counterweight 5 attached to the side frame 3, and both side surfaces and the top surface are covered by an engine hood 6 that can be opened on both sides. A stay 7 for attaching an engine hood is arranged at a substantially central position above the engine room 1 and extends parallel to the front-rear direction.
The front end is fastened to a bracket 8 fixed to the front frame 4 by a bolt 9, and the rear end is fixed to a bracket 10 fixed to a beam 10 horizontally fixed between the front upper part of the counterweight 5.
1 with bolts 12, and can be removed as necessary. Left and right engine hoods 6, each formed in a substantially L-shape, are attached to the stay 7 supported as described above so as to be openable and closable by hinges 13, respectively. Note that 14 is a cover that covers the upper surface of the U-shaped space of the counterweight 5 (which usually accommodates a radiator).

As shown in FIG. 2, the air cleaner 15 is disposed above the engine 16 housed in the engine room 1 so that its axial direction is parallel to the vehicle width direction. A cleaner bracket 17 is fastened to the lower surface of the stay 7 with bolts 18. That is, the air cleaner 15 is supported by the stay 7 in a suspended manner above the engine. In this embodiment, since the engine 16 is a diesel engine, the cleaner hose 19 of the air cleaner 15
is connected to the intake pipe 20, but in the case of a gasoline engine, it is connected to the carburetor. 21 is an element cover that is removably fitted to the cleaner body.

This embodiment uses the air cleaner 15 as described above.
Therefore, compared to the conventional type in which the air cleaner is placed side by side with the engine, it is possible to have more space around the engine, making service work easier. Since the cleaner hose 19 can be as close as possible to the cleaner hose 19, the cleaner hose 19 can be shortened and piping resistance can be reduced. In addition, since the direction of entry and exit of the air cleaner element is toward the side of the vehicle body,
When servicing work is performed while standing on the side of the vehicle, replacing the element of the air cleaner 15, including attaching and detaching the element cover 21, is extremely easy.
Furthermore, since the air cleaner 15 is supported using the stay 7 for attaching the engine hood, there is no need to increase the cost of attachment parts for the air cleaner.

Although the present embodiment has been described as a case of a forklift, the present invention is not limited to this, and can also be applied to, for example, a shovel loader.

Effects of the invention As detailed above, the present invention satisfies the various conditions required when installing the air cleaner in the engine room, namely, ease of air cleaner element replacement, and ease of service within the engine room. This satisfies the following conditions: good performance, low piping resistance of the air cleaner, and low cost of air cleaner attachment parts.
In particular, in this invention, the air cleaner is supported in a suspended manner on the stay for mounting the double-opening engine hood, which reduces the vehicle's performance compared to the case where the air cleaner is supported with a bracket placed across directly above the engine. When performing service work inside the engine room while standing on the side, there is no member blocking the side upper part of the engine, making it possible to easily perform service work using a large space and using existing stays. Since it is a supporting structure, it is effective in reducing the cost of attached parts, and is a practically useful idea as a support structure for an air cleaner.
