Description

[Detailed description of the invention] a. Industrial application field The present invention relates to a mounting structure for an air dryer device.

b. Prior Art Air dryer devices have been conventionally used to dry compressed air in air brake devices for vehicles. An example of this type of air dryer is shown in FIG. 4.

The air dryer device A shown in FIG. 4 includes a cylindrical housing 1 having an open end, a storage case 4 disposed in a purge chamber 2 in the housing 1 and storing a desiccant 3 inside, and a housing 1. 1 and an end cover 5 that closes the open end of the opening end. Thus, in the compressed air supply process, the air dryer A described above supplies compressed air from a compressor (not shown) to the filter 6 in the storage case 4, the desiccant 3 in the desiccant storage chamber 4a, the purge chamber 2, and the back check. The compressed air in the purge chamber 2 is supplied to an air reservoir (not shown) through the valve 7, and in the desiccant regeneration process, by opening the purge valve 8 provided on the end cover 5, the compressed air from the purge chamber 2 is passed through the desiccant storage chamber 4a. It is designed to be released into the atmosphere.

By the way, to attach this device A to the vehicle body, for example, two belt-shaped attachment members 9 are wound around the outer periphery of the cylindrical housing 1 only once, and both ends 9' are tightened together with bolts or the like. This was done by tightening the mounting member 9, and then tightening and fixing both ends 9' of the mounting member 9 to the vehicle body using bolts, nuts, etc.

c. Problems to be solved by the invention However, when the air dryer device A is attached and fixed to the vehicle body using the mounting member 9 as described above, the device A cannot be attached due to vibrations of the vehicle, changes over time, etc. There was a high possibility that the member would fall off unexpectedly. That is, two mounting members 9
No matter how strongly the housing 1 is tightened by the mounting member 9, the tightening force due to surface contact alone will cause the housing 1 to
This is because it is easy to slip down.

In addition, in the conventional structure, the tightening work of both ends 9' of the mounting member 9 with bolts or the like is done without any restrictions, so it is easy to overtighten, and in such a case, the mounting member 9 Also, there is a problem that problems such as the housing 1 being deformed or damaged occur.

The present invention was devised in view of the above-mentioned circumstances, and its purpose is to provide an air dryer device with an appropriate binding force using a belt-shaped mounting member, although the structure is extremely simple. It is an object of the present invention to provide a mounting structure that can be fastened (tightened and fixed) and also allows an air dryer device to be securely mounted without fear of falling off.

d Means for Solving the Problems In order to solve the above-mentioned problems, the present invention includes a housing having an open end, a desiccant storage case disposed within the housing, and a desiccant storage case disposed within the housing. In a mounting structure for mounting an air dryer device, each including an end cover for closing an open end, at a predetermined location using a belt-shaped mounting member, a convex portion or a recess is formed on the outer periphery of the housing, and A concave portion or a convex portion corresponding to the convex portion or concave portion is formed in a longitudinally intermediate portion of the member, and the intermediate portion of the mounting member is placed around the housing so that the convex portion and the concave portion engage with each other. In the rolled state, an intervening member having a substantially U-shaped cross section is disposed between a pair of opposing portions that extend to both ends of the intermediate portion of the mounting member and are arranged to face each other. By tightening the parts with bolts and nuts, the housing is bound by the mounting member, and both ends of the mounting member extending to the pair of opposing parts are mounted at predetermined locations.

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 1 to 3. 1 and 2 that are common to those in FIG. 4 are designated by the same reference numerals and their explanations will be omitted.

As shown in FIGS. 1 and 3a, in this embodiment, a convex portion 15 is formed on the outer circumference of the cylindrical housing 1, and a convex portion 15 corresponding to the convex portion 15 is formed on the belt-shaped mounting member 9. The recess 16 is press-molded. Note that the above-described protrusions 15 are dot-shaped protrusions (point protrusions), and are formed at, for example, four locations on the outer circumference of the housing 1 at equal intervals.

As shown in FIG.
It is formed by bending and forming a plate-shaped body, and includes a pair of both end pieces 9a extending on the same plane, an annular portion 9b formed in the center, both ends of the annular portion 9b, and the pair of end pieces 9a extending on the same plane. and a pair of opposing portions 9c that are opposed to each other and are formed between both end pieces 9a. Bolt insertion holes 17a and 17b are formed in the pair of opposing portions 9c, respectively, and mounting holes 18a and 18b are formed in both end pieces 9a bent in opposite directions, respectively.

Therefore, when installing the air dryer device A to a vehicle body or the like, the annular portions 9b of the two mounting members 9 are wrapped around the housing 1 as shown in FIG. 16 are engaged with each other. Then, an intervening member 19 having a substantially U-shaped cross section is placed between the pair of opposing portions 9c of the mounting member 9, and the opposing portions 9c are tightened with bolts 20 and nuts 21. Accordingly, the housing 1 is tied with an appropriate binding force by the mounting member 9, and the housing 1 and the annular portion 9b of the mounting member 9 are in a state where the protrusion 15 and the recess 16 are engaged with each other. Installed integrally with a fastener at the bottom. Next, both ends 9a of the mounting member 9 are applied to a predetermined mounting location on the vehicle body and fixed by tightening with bolts, set screws, etc. not shown.

In this way, when the air dryer device A is attached to the vehicle body, the convex portion 15 and the concave portion 16
Due to the engagement action with the mounting member 9, the device A will not accidentally fall off from the mounting member 9. Furthermore, the fact that the recessed portion is provided in the mounting member 9 by press molding means that the convex portion 16' is provided on the side opposite to the housing 1.
The presence of this convex portion 16' increases the strength of the mounting member 9.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and various modifications and changes can be made based on the technical concept of the present invention.

For example, in the embodiment described above, four point protrusions are formed on the outer periphery of the housing 1, but the number is not limited to four, and a series of linear protrusions may be formed on the entire outer periphery of the housing 1. You can do it like this.

Further, as shown in FIG. 3B, a recess 22 may be formed on the outer periphery of the housing 1, and a protrusion 23 corresponding to the recess 22 may be formed on the mounting member 9.

e. Effects of the invention As described above, the present invention forms a protrusion and a recess that correspond to each other on the housing and the mounting member of the air dryer device, and when the protrusion and the recess are engaged with each other, the above-mentioned An intervening member having a substantially U-shaped cross section is arranged between opposing parts of the mounting member, and the pair of paired parts are tightened with bolts and nuts, thereby tightening and attaching the device. , although it has a very simple configuration,
The engagement between the convex portion and the concave portion makes it possible to reliably prevent the device from falling off unexpectedly. There is also the advantage that the strength of the mounting member can be increased.

Further, according to the present invention, due to the presence of the intervening member having a substantially U-shaped cross section, the binding force of the mounting member to the housing can be set appropriately, and therefore, the uneven engagement portion and the entire housing can be deformed due to over tightening. It is possible to prevent damage to the uneven parts.

In addition, since the housing is tightened with an appropriate binding force by the mounting member, it is possible to prevent the housing from rattling due to vehicle vibration, and even if the housing is slightly deformed due to changes over time, that deformation can be prevented. The binding force can be sufficiently absorbed and a good supporting state can be maintained at all times.

Moreover, as mentioned above, the presence of the intervening member allows the binding force to be set appropriately and prevents deformation and damage of the unevenness, so that the unevenness can be formed with simple point protrusions using a press. This is advantageous in terms of manufacturing workability and cost.
