Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a seal rubber for a horizontal air cleaner used, for example, in a cab-over type freight vehicle.

``Prior art'' For example, in a cab-over type truck, etc., it is necessary to store the engine device in a relatively narrow space below the driver's seat. The overall height of the engine was kept as low as possible by placing air cleaners side by side.

Therefore, it is not possible to use a conventional vertical air cleaner that can be divided into upper and lower halves as an air cleaner, and for example, a horizontal air cleaner as shown in FIG. many.

In this horizontal air cleaner, a filter member (element) c whose axis is oriented horizontally is disposed in cleaner cases a and b that are divided into left and right parts along the axis, and air is filtered into the cleaner cases a and b, respectively. A discharge port d and a suction port e are formed in the horizontal direction, and after the intake air is purified from the suction port e through a filter member c, it is supplied to a carburetor (not shown) through the discharge port d. At this time, a frame-shaped sealing rubber f is installed in the gap to prevent dirty air from being sucked through the gap between the filter member c and the joints of the cleaner cases a and b.

``Problems with the prior art'' However, in cab-over type automobiles that use such horizontal air cleaners, as mentioned above, the space for storing the engine equipment is relatively small, and the air cleaner is also relatively long due to poor heat dissipation. The seal rubber is often exposed to high temperatures for hours, and this adverse environment corrodes the seal rubber, causing the problem that the seal rubber f is adhered to the cleaner case. In particular, the cleaner case b side is in close contact with the seal rubber f over a wider area than the cleaner case a, and in the case of the conventional seal rubber f shown in Fig. 5, the seal rubber f and the filter member c are Since the seal rubber f does not have a suitable protrusion for separating it from the cleaner case b, in order to separate the seal rubber f and the filter member c from the cleaner case b, a knife or a The rubber seal f was peeled off by inserting the tip of a screwdriver or the like and prying it open. However, this separation method requires a lot of time and has poor workability.

In addition, in the conventional seal rubber f mentioned above, a part of the seal rubber f hangs down toward the shaft center from the outer circumference of the seal rubber f, but this is for positioning the filter member c against it. One side of this hanging portion is in close contact with the surface of the filter member c. Therefore, it is impossible to grasp the hanging portions as described above in order to separate the seal rubber f and the filter member c from the cleaner case b.

``Purpose of the invention'' Therefore, the purpose of the present invention is to develop a structure for the seal rubber used in the above-mentioned horizontal air cleaner, which can be easily removed from the cleaner case and improve workability. It is about providing.

"Structure of the invention" In order to achieve the above object, the main means adopted by the invention is to store the filter member in a cleaner case that can be divided into left and right sides along the axis so that the axis is oriented horizontally. In the horizontal air cleaner, at least two or more protrusions are provided at a predetermined pitch and spaced apart from the filter member on the outer periphery of the frame-shaped seal rubber filled between the joint of the filter member and the cleaner case. Among the above components, the protrusions are not protrusions extending all the way around the frame-shaped seal rubber, but rather two or more fragmentary protrusions formed at a predetermined pitch on a part of the seal rubber, and the protrusions that are filtered by this The area of the passage is not reduced and problems such as pressure loss are avoided.

``Example'' Next, an example embodying the present invention will be described with reference to FIGS. 1 to 4. Here, FIG. 1 is a side sectional view of a horizontal air cleaner using a seal rubber according to an embodiment of the present invention, FIG. 2 is a front view of the same seal rubber, and FIG. 3 is a horizontal sectional view using a seal rubber according to another embodiment of the present invention. Side sectional view of air cleaner, No. 4
The figure is a front view of the same seal rubber.

Note that the same reference numerals are used for the same elements as those shown in FIG. 5 for explanation.

In the embodiment shown in FIGS. 1 and 2, a wire mesh 1 is disposed on the cleaner case a side at right angles to the axis of the filter member c to protect the filter member c from the backflow of hot air from the discharge port d. It shows a horizontal air cleaner like the one shown below.

In this case, the frame-shaped seal rubber 2 is divided into four pieces from the inner circumferential surface 3 toward the axis of the seal rubber 2 for sealing the gap between the filter member c and the joints of the cleaner cases a and b. Projecting pieces 4 are provided at approximately equal intervals in the circumferential direction and projecting apart from the back surface of the filter member c. The protrusion piece 4 is
It is used to hold the seal rubber 2 when peeling it off from inside the divided cleaner case. In this case, as described above, the protruding pieces 4 are provided spaced apart from the back surface of the filter member c, and a plurality of protrusions 4 (in this embodiment, 4 protrusions) are provided in the circumferential direction of the seal rubber 2.
filter member c and seal rubber 2, which do not have any direction of installation with respect to the shaft
When removing the cleaner case from the cleaner case, the projection piece 4 can be easily grasped and taken out. Furthermore, even if the seal rubber 2 becomes glued to the cleaner case all around the circumference due to corrosion, the seal rubber 2
Since the sealing rubber 2 can be peeled off from a plurality of parts, the sealing rubber 2 will not be torn or broken. Furthermore, the length l (FIG. 2) of the protruding piece 4 along the inner circumferential surface 3 is much smaller than the total length of the inner circumferential surface 3, and is only partially formed.
The area of this protruding piece 4 is the inner passage 5 of the seal rubber 2.
much smaller than the area of Therefore, the reduction in the amount of intake air caused by the protruding piece 4 is negligible.

Although the protruding piece 4 described above can be formed on the lip portion 2' of the seal rubber 2, it is possible to increase the area of the space that accommodates the lip portion 2' between the filter member c and the cleaner case b to some extent. Such considerations are necessary.

In the case of the embodiment shown in FIGS. 1 and 2 above,
Although an example has been shown in which the protrusion piece 4 is made to protrude toward the center of the seal rubber 2 along the wire mesh 1, in the case of a horizontal air cleaner without the wire mesh 1 as described above, the third
As shown in FIG. 4, the protrusion piece 4a can be made to protrude along the axis of the seal rubber 2 in the direction of the discharge port d, and in this case, the internal passage 5 of the seal rubber 2 is blocked by the protrusion piece 4a. There is no such possibility. The seal rubber 2 and the filter member c are integrally formed by adhesive means or the like, and when the filter member is replaced, the seal rubber is also replaced at the same time.

In any of the above embodiments, when replacing the filter member c, it is necessary to separate the seal rubber 2 attached to the cleaner cases a and b, but in this case, it is necessary to separate both the cleaner cases a and b. At this time, the seal rubber 2 will arrive at the side that has a larger adhesive area with the cleaner case. Therefore, with the proposed configuration, the seal rubber 2 is removed with it still attached to the cleaner case b, and compared to the case where the seal rubber 2 is attached to the cleaner case a, the filter member can be replaced after being removed from the narrow engine room. Work efficiency is further improved. When removing the seal rubber 2 and filter member c from the cleaner case b,
By holding the projection piece 4 or 4a and pulling it, it can be easily removed without using a screwdriver or the like.

"Effects of the Invention" As described above, the present invention provides a horizontal air cleaner in which the filtration member is housed in a cleaner case that can be divided into left and right sides along the axis so that the filtration member is oriented horizontally. A seal rubber for a horizontal air cleaner, characterized in that at least two protrusions are provided at a predetermined pitch on the outer periphery of a frame-shaped seal rubber filled between the joint part of the cleaner case and spaced apart from the filter member. Therefore, even in horizontal air cleaners where the seal rubber tends to stick to the cleaner case due to exposure to high heat, the seal rubber can be easily peeled off from the cleaner case when replacing the filter member, reducing the number of work steps. Work efficiency can be improved.
