Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This idea uses a center bolt in the center of the closed end plate of the air cleaner element. Regarding the air cleaner element, which is held by tightening the element with a wing nut. In particular, it is a technology related to weight reduction.

0002

[Conventional technology]

Among the air cleaners used in the intake system of automobile engines, filter elements A structure in which the component is fixed with a center bolt located in the axial direction of the air cleaner. It has been known. In this structure, there is a center bolt in the center of the closed end plate of the element. Thread the wing nut onto the end of the wing nut and tighten to hold the element in place. has been done. However, in this structure, the closed end plate is attached to the element by tightening it with a wing nut. Since it requires strength to withstand fitting and holding, the open upper end plate of the element and the closed The lower end plate was a metal plate, which caused the following problems.

0003

[Problem that the idea aims to solve]

In other words, in the conventional structure described above, the open end plate and the closed end plate of the filter element Since it is made of metal, it is heavy and hinders weight reduction. Since the element is heavy, cleaning and replacing the element is difficult. There are problems with the maintainability of the elements of the It went against all demands. To solve this problem, we have replaced the edge plate with synthetic resin. However, if the edge plate is simply replaced with synthetic resin, the center bolt Those with a tightening structure cannot provide that strength.

0004 This invention solves the above problem and The end plates are made of synthetic resin, and only the central part, which requires the strength of the closed end plate, is made of metal, and the other parts are made of metal. aims to provide a lightweight element made of synthetic resin.

[0005]

[Means to solve the problem]

In order to achieve the above object, this invention uses a filtration member folded in a zigzag shape. an open end plate that closes an upper part of the filtration member; a closed end plate that closes a lower part of the filtration member; The air cleaner is secured by inserting a center bolt through the center of the closed end plate and tightening it with a wing nut. In the filter element for filter elements, the open end plate is made of synthetic resin, and the closed end plate is made of synthetic resin. The plate includes a synthetic resin ring-shaped portion provided at the end of the filter element; It is integrally molded with the outer periphery buried in this ring-shaped part, and the center is closed. a metal plate, and a plurality of through holes are provided in the buried portion of the metal plate. shall be.

[0006]

[Effect]

According to the above configuration, the element is inserted through the center bolt of the air cleaner. The closed end plate, which is held by tightening with nuts, uses metal plates only in the parts that require strength. Since the rest of the parts are made of synthetic resin, it is possible to make the air cleaner lighter. .

【Example】

Figures 1, 2(a) and 2(b) show an embodiment of the air cleaner according to this invention. ing. In Figure 1, 1 is a suction pipe that takes in outside air, and suction pipe 1 is the case body. It is fixed on the side of 3. 2 is the intake of purified air into the engine (not shown) Outlet pipe 4 is a cover that connects to the pipe, and a center bolt 5 is passed through the center of the cover, and a wing nut 6 is attached. is tightened and held in the case body 3.

[0008] Reference numeral 7 denotes an element support bracket whose upper end is fixed to the outlet pipe 2. 8 is ele Pass the center bolt 5 through the center of the closing plate 14 using the An opening 12 is pressed onto the upper surface of the body 3 via a packing 11 and provided at the upper end. Exhaust purified air from the The element 8 has a filter member 9. , this filter member 9 is made of mountain folds and valleys made by bending a non-woven fabric or the like into a jagged shape at a constant pitch. It has a folded part and is assembled into an annular shape with a perforated inner cylinder 10 arranged inside.

[0009] An open end plate 13 made of synthetic resin is arranged on the upper end side of the filter member 9. A soft packing 11 is integrally formed on the upper surface of the plate 13 by two-color molding or the like. There is. A closed end plate 14 is provided at the bottom of the filter member 9. This closed end plate 14 The central part is a metal plate 14a, and the outer periphery of this metal plate 14a is a ring made of synthetic resin. It is a shaped portion 14b. The outer peripheral edge of this metal plate 14a is connected to the lower end of the filter member 9. It is buried in the provided ring-shaped portion 14b.

0010 The metal plate 14a and the ring-shaped portion 14b are joined by integral molding. In order to ensure the strength of this bond, a plurality of penetrations are provided in the buried portion of the metal plate 14a. A through hole 14c is provided, and when forming the ring-shaped portion 14b in this portion, resin is applied. flows in and strengthens these bonds.

[0011] The filter element with the above configuration has a cylindrical case body 3 as shown in FIG. It is housed inside and covered with a cover 4, and sucks in outside air containing dust from the suction pipe 1. The filtered air is filtered by the filter member 9 of the filter member 8, and the purified air passes through the outlet pipe 2 from the opening 12. and is inhaled into the engine.

0012 In this case, in the present invention, the open end provided at the upper part of the filter member 9 of the element 8 The plate 13 is made of synthetic resin, and a closed end plate 14 is provided at the lower part of the filter member 9. Since a part of the element 8 is made of synthetic resin, the weight of the element 8 can be reduced. Further, the closed end plate 14 has a synthetic resin ring at a portion approximately the same length as the width of the filter member 9. The outer peripheral edge of the metal plate 14a is embedded in the ring-shaped portion 14b. Since the metal plate 14a is integrally molded with the center bolt 5 in the center of the metal plate 14a, Even if you insert it, screw the wing nut 15 onto the center bolt 5, and tighten it, it will not tighten. Since the part to be fitted is the metal plate 14a, it has sufficient strength.

[0013]

[Effect of the idea]

As described above in detail with reference to the embodiments, the air cleaner flap according to this invention The filter element has an upper open end plate made of synthetic resin and a lower closed end plate made of synthetic resin. The central part, which requires strength, is a metal plate, and the outer edge is embedded and held inside the synthetic resin. A through hole is provided in this embedded part to ensure the integrity of the metal and synthetic resin. As a result, weight reduction can be achieved while ensuring the tightening strength of the center bolt. .
