Description

[Technical field]

[0001] The present invention relates to an air dryer mounting structure for mounting an air dryer that dehumidifies compressed air stored in an air tank to a vehicle frame. [Background technology]

[0002] Vehicles such as trucks use compressed air sent from an air compressor to control systems such as brakes. However, if compressed air containing moisture and oil gets into each system, it can cause malfunctions such as rust. For this reason, such vehicles are equipped with an air dryer that removes moisture and oil from the compressed air, in addition to an air tank that stores the compressed air. The air dryer is usually supported by an air dryer support bracket that is fixed to a frame (side rail) that extends in the fore-and-aft direction of the vehicle (see, for example, Patent Document 1).

[0003] [Patent Document 1] JP 22010-254009 A Summary of the Invention [Problem to be solved by the invention]

[0004] Meanwhile, an air dryer is a heavy object, similar to an air tank. For this reason, it is necessary to increase the rigidity of the air dryer support bracket by, for example, increasing the complexity and size of the air dryer support bracket. However, when the air dryer support bracket becomes more complex and larger, problems arise in terms of cost, weight reduction, and workability. For example, when the air dryer support bracket becomes more complex and larger, the manufacturing cost of the air dryer support bracket increases, the weight of the air dryer support bracket increases, and the work space for assembling the air dryer to the frame becomes narrower.

[0005] Therefore, an object of the present invention is to provide an air dryer mounting structure that can improve workability while suppressing increases in cost and weight. [Means for solving the problem]

[0006] The air dryer mounting structure of the present invention is an air dryer mounting structure for mounting an air dryer to a frame extending in the fore-and-aft direction of the vehicle, and comprises an air tank support bracket fixed to the frame and extending in the vehicle width direction to support the air tank, an air dryer support bracket fixed to the frame and extending in the vehicle width direction to support the air dryer, and a restricting bracket connected to the air tank support bracket and the air dryer support bracket for restricting movement of the air dryer support bracket in the fore-and-aft direction of the vehicle relative to the air tank support bracket.

[0007] In this air dryer mounting structure, the restricting bracket is connected to the air dryer support bracket and the air tank support bracket, thereby restricting movement of the air dryer support bracket in the fore-and-aft direction of the vehicle relative to the air tank support bracket. This makes it possible to properly support the air dryer without increasing the rigidity of the air dryer support bracket by making it more complex and larger. In this way, the provision of the restricting bracket allows the air dryer support bracket to have a simple configuration that extends in the vehicle width direction, thereby suppressing increases in cost and weight and improving workability.

[0008] The air tank support bracket may have a higher rigidity in the vehicle fore-and-aft direction than the air dryer support bracket. In this air dryer mounting structure, the air tank support bracket has a higher rigidity in the vehicle fore-and-aft direction than the air dryer support bracket, thereby effectively restricting movement of the air dryer support bracket in the vehicle fore-and-aft direction.

[0009] The restricting bracket may allow the air dryer support bracket to move in the vehicle up-down direction relative to the air tank support bracket. In this air dryer mounting structure, the restricting bracket allows the air dryer support bracket to move in the vehicle up-down direction relative to the air tank support bracket, thereby suppressing the mutual influence of the vehicle up-down vibration of the air dryer and the vehicle up-down vibration of the air tank when the vehicle is subjected to vibration in the vehicle up-down direction from the road surface. This makes it possible to suppress an increase in the vehicle up-down vibration of the air tank and the air dryer.

[0010] The regulating bracket may have an intermediate portion formed in a plate shape extending in the vehicle fore-and-aft direction and the vehicle width direction and forming at least a part between the air tank support bracket and the air dryer support bracket in the vehicle fore-and-aft direction. In this air dryer mounting structure, the intermediate portion of the regulating bracket forming at least a part between the air tank support bracket and the air dryer support bracket in the vehicle fore-and-aft direction is formed in a plate shape extending in the vehicle fore-and-aft direction and the vehicle width direction, thereby making it possible to appropriately permit movement of the air dryer support bracket in the vehicle up-and-down direction relative to the air tank support bracket.

[0011] In the vehicle width direction, the first connection position between the restraining bracket and the air dryer support bracket may be the same as the support position of the air dryer by the air dryer support bracket or a position farther from the frame than the support position. In this air dryer mounting structure, by having the first connection position between the restraining bracket and the air dryer support bracket in the vehicle width direction be the same as the support position of the air dryer by the air dryer support bracket or a position farther from the frame than the support position, movement of the air dryer support bracket supporting the air dryer in the vehicle fore-and-aft direction can be effectively restricted.

[0012] In the vehicle width direction, the second connection position between the restraint bracket and the air tank support bracket may be closer to the frame than the first connection position between the restraint bracket and the air dryer support bracket. In this air dryer mounting structure, the second connection position between the restraint bracket and the air tank support bracket is closer to the frame than the first connection position between the restraint bracket and the air dryer support bracket in the vehicle width direction, so that the force in the rotational direction about the fixed position with the frame input to the air dryer support bracket can be appropriately received by the restraint bracket and the air tank support bracket. This makes it possible to more effectively restrict movement of the air dryer support bracket in the vehicle fore-aft direction.

[0013] The air dryer support bracket may have a fixing portion extending in the vehicle front-rear direction to be fixed to the frame, and a support portion extending in the vehicle width direction from the fixing portion to support the air dryer. In this air dryer mounting structure, the air dryer support bracket can mount the air dryer to the frame using the fixing portion and the support portion that are arranged in a substantially L-shape, so that the regulating bracket can have a simple configuration. This makes it possible to further suppress increases in cost and weight and further improve workability.

[0014] The support portion of the air dryer support bracket may be formed in a plate shape extending in the vehicle width direction and the vehicle up-down direction. In this air dryer mounting structure, the support portion of the air dryer support bracket is formed in a plate shape extending in the vehicle width direction and the vehicle up-down direction, so that the support force of the air dryer in the vehicle width direction and the vehicle up-down direction can be increased while the air dryer support bracket has a simple structure, etc.

[0015] The air tank support bracket may be formed with a U-shaped cross section. In this air dryer mounting structure, the air tank support bracket is formed with a U-shaped cross section, thereby making it possible to increase the rigidity of the air tank support bracket. Effect of the Invention

[0016] According to the present invention, it is possible to improve workability while suppressing increases in cost and weight. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. In the following description, the same or corresponding elements are denoted by the same reference numerals, and duplicated description will be omitted. In the following description, directions such as up and down refer to directions such as up and down in a vehicle.

FIG. 3 is a plan view showing an air dryer mounting structure according to an embodiment. FIG. 4 is a perspective view showing an air dryer mounting structure according to an embodiment. FIG. 5 is a side view showing an air dryer mounting structure according to an embodiment. FIG. 6 is a plan view showing an air dryer mounting structure according to an embodiment. As shown in FIGS. 1 to 6, an air dryer mounting structure 1 according to this embodiment is a structure for mounting air tanks 4, 4 and an air dryer 5 to a frame 3 extending in the vehicle front-rear direction in a vehicle 2. In addition, in FIGS. 1 to 6, FR indicates the front in the vehicle front-rear direction, RH indicates the right in the vehicle width direction, and UP indicates the upper side in the vehicle up-down direction. In addition, in FIGS. 1 to 3, the air tanks 4, 4 and the air dryer 5 have been removed to make the structure of each bracket easier to see.

[0020] The frames 3 are also called side rails. The vehicle 2 is provided with two frames 3, which are arranged side by side in the vehicle width direction so as to face each other. The air dryer 5 is attached to at least one of the two frames 3. In this embodiment, the air dryer 5 is attached to the right frame 3 of the two frames 3.

[0021] The air tanks 4, 4 are attached to the frame 3 and store compressed air sent from an air compressor (not shown).

[0022] The air dryer 5 removes moisture and oil from the compressed air sent from an air compressor (not shown). The air dryer 5 is disposed, for example, upstream of the air tanks 4, 4 in the flow direction of the compressed air.

[0023] The air dryer mounting structure 1 comprises air tank support brackets 11A, 11B, a connection bracket 12, an air dryer support bracket 13, an auxiliary bracket 14, and a regulating bracket 15.

[0024] The air tank support brackets 11A, 11B are brackets for supporting the air tanks 4, 4. Since the air tank support bracket 11A and the air tank support bracket 11B basically have the same structure, they will be collectively described below as the air tank support bracket 11 unless otherwise specified. The air tank support bracket 11 is fixed to the frame 3 to support the air tanks 4, 4 and extends to the right RH in the vehicle width direction. The air tank support bracket 11 has a fixing portion 11a fixed to the frame 3 and a support portion 11b that supports the air tanks 4, 4.

[0025] The fixed portion 11a and the support portion 11b are formed in a long and thin arm shape. The fixed portion 11a extends in the vehicle vertical direction, and the support portion 11b extends in the vehicle width direction so that the fixed portion 11a and the support portion 11b are arranged in a substantially L-shape. The support portion 11b extends to the right RH in the vehicle width direction relative to the fixed portion 11a. The fixed portion 11a and the support portion 11b may be connected in a bent manner, or may be connected in a curved manner. In this embodiment, the fixed portion 11a and the support portion 11b are connected in a curved manner.

[0026] The fixing portion 11a is fixed to a side surface of the frame 3. The fixing portion 11a can be fixed to the frame 3 by, for example, bolting or the like. The air tanks 4, 4 can be supported by the support portion 11b by, for example, placing the air tanks 4, 4 on the support portion 11b and fixing a metal band 21 wrapped around the air tanks 4, 4 to the air tank support bracket 11. The metal band 21 can be fixed to the air tank support bracket 11 by, for example, bolting or the like. The metal band 21 is fixed to at least one of the fixing portion 11a and the support portion 11b.

[0027] The air tank support bracket 11 is formed with a U-shaped cross section so that the rigidity in the vehicle longitudinal direction is higher than that of the air dryer support bracket 13. In other words, the air tank support bracket 11 has a higher rigidity in the vehicle longitudinal direction than that of the air dryer support bracket 13. The fixing portion 11a has a base 11d that extends in the vehicle longitudinal direction and the vehicle vertical direction so as to face the frame 3 and is bolted to the frame 3, and a pair of flange portions 11e, 11e that extend to the right RH in the vehicle width direction from both ends of the base 11d in the vehicle longitudinal direction. The support portion 11b has a base 11f that extends in the vehicle longitudinal direction and the vehicle width direction so as to extend from the base 11d of the fixing portion 11a, and a pair of flange portions 11g, 11g that extend upward UP in the vehicle vertical direction from both ends of the base 11f in the vehicle longitudinal direction.

[0028] Fig. 7 is an enlarged perspective view of a part of the air dryer mounting structure. As shown in Figs. 1 to 7, the connection bracket 12 is a bracket for connecting the air tank support bracket 11B and the air dryer support bracket 13. In this embodiment, the air dryer 5 is disposed in the front FR of the air tank support brackets 11A and 11B in the vehicle front-rear direction, so the connection bracket 12 is connected to the air tank support bracket 11B. However, when the air dryer 5 is disposed behind the air tank support brackets 11A and 11B in the vehicle front-rear direction, the connection bracket 12 is connected to the air tank support bracket 11A. The connection bracket 12 has an air tank side connection part 12a connected to the air tank support bracket 11B and an air dryer side connection part 12b connected to the air dryer support bracket 13.

[0029] The air tank side connecting portion 12a is formed in a plate shape extending in the vehicle front-rear direction and the vehicle up-down direction, and is connected to the base portion 11d of the fixing portion 11a of the air tank support bracket 11B. The air tank side connecting portion 12a can be connected to the air tank support bracket 11B by, for example, welding, bolt fastening, or the like.

[0030] The air dryer side connection part 12b extends forward FR in the vehicle fore-and-aft direction from the air tank side connection part 12a, and its tip is detachably connected to the air dryer support bracket 13. The detachable connection between the air dryer side connection part 12b and the air dryer support bracket 13 can be achieved, for example, by bolt fastening or the like.

[0031] The air dryer support bracket 13 is a bracket for supporting the air dryer 5. The air dryer support bracket 13 is fixed to the frame 3 and extends in the vehicle width direction in order to support the air dryer 5. The air dryer support bracket 13 has a fixing portion 13a that is fixed to the frame 3 and connected to the air dryer side connection portion 12b of the connection bracket 12, and a support portion 13b that supports the air dryer 5.

[0032] The air dryer support bracket 13 is formed such that the fixing portion 13a and the support portion 13b are substantially L-shaped. The fixing portion 13a is formed in a plate shape extending in the vehicle front-rear direction and the vehicle up-down direction so as to follow the frame 3, and the support portion 13b is formed in a plate shape extending in the vehicle width direction and the vehicle up-down direction so as to be perpendicular to the frame 3. The support portion 13b extends to the right RH in the vehicle width direction relative to the fixing portion 13a. The fixing portion 13a and the support portion 13b may be connected in a bent manner or may be connected in a curved manner. In this embodiment, the fixing portion 13a and the support portion 13b are connected in a curved manner.

[0033] The fixing portion 13a is fixed to a side surface of the frame 3. Fixing of the fixing portion 13a to the frame 3 and connection of the fixing portion 13a to the air dryer side connection portion 12b of the connection bracket 12 can be performed, for example, by bolting the fixing portion 13a and the air dryer side connection portion 12b to the frame 3 in a state in which the fixing portion 13a and the air dryer side connection portion 12b are overlapped. Support of the air dryer 5 to the support portion 13b can be performed, for example, by fixing a base portion 22 on which the air dryer 5 is placed to the support portion 13b and fixing a metal band 23 wrapped around the air dryer 5 to the support portion 13b. Fixing of the base portion 22 and the metal band 23 to the support portion 13b can be performed, for example, by bolting.

[0034] The auxiliary bracket 14 is a bracket for suppressing bending deformation of the support portion 13b relative to the fixed portion 13a in the vehicle longitudinal direction. The auxiliary bracket 14 is formed in a plate shape extending in the vehicle longitudinal direction and the vehicle width direction, and is fixed at both ends to the fixed portion 13a and the support portion 13b. The auxiliary bracket 14 can be fixed to the fixed portion 13a and the support portion 13b by, for example, welding, bolt fastening, or the like.

[0035] The restricting bracket 15 is a bracket connected to the air tank support bracket 11B and the air dryer support bracket 13. The restricting bracket 15 restricts movement of the air dryer support bracket 13 in the front-to-rear direction of the vehicle relative to the air tank support bracket 11B. The restricting bracket 15 also allows movement of the air dryer support bracket 13 in the up-down direction of the vehicle relative to the air tank support bracket 11B. The restricting bracket 15 has an air tank side fixing portion 15a, an air dryer side fixing portion 15b, and an intermediate portion 15c.

[0036] The air tank side fixing part 15a is fixed to the air tank support bracket 11B. For example, the air tank side fixing part 15a is fixed to the base part 11f in a state where it is overlapped with the base part 11f of the support part 11b of the air tank support bracket 11B. Like the base part 11f, the air tank side fixing part 15a is formed in a plate shape extending in the vehicle front-rear direction and the vehicle width direction. The air tank side fixing part 15a can be fixed to the air tank support bracket 11B by, for example, bolt fastening.

[0037] The air dryer side fixing part 15b is fixed to the air dryer support bracket 13. The air dryer side fixing part 15b is fixed to the support part 13b of the air dryer support bracket 13, for example, in a state where it is overlapped on the support part 13b. The air dryer side fixing part 15b is formed in a plate shape extending in the vehicle width direction and the vehicle up-down direction, similar to the support part 13b. The air dryer side fixing part 15b can be fixed to the air dryer support bracket 13 by, for example, bolt fastening.

[0038] The intermediate portion 15c is a portion disposed between the air tank side fixing portion 15a and the air dryer side fixing portion 15b. That is, the intermediate portion 15c is a portion that forms at least a part between the air tank support bracket 11B and the air dryer support bracket 13 in the vehicle longitudinal direction. The intermediate portion 15c is formed in a plate shape extending in the vehicle width direction and the vehicle longitudinal direction. Therefore, the intermediate portion 15c is capable of bending and deforming so that the air tank side fixing portion 15a and the air dryer side fixing portion 15b move relatively in the vehicle vertical direction. As a result, the regulating bracket 15 is configured to allow the air dryer support bracket 13 to move in the vehicle vertical direction relative to the air tank support bracket 11B by the intermediate portion 15c, and is configured to allow the air dryer support bracket 13 to move in the vehicle vertical direction relative to the air tank support bracket 11B.

[0039] Here, as shown in Figure 6, the connection position between the regulating bracket 15 and the air dryer support bracket 13 is defined as a first connection position P1, the connection position between the regulating bracket 15 and the air tank support bracket 11B is defined as a second connection position P2, and the support position of the air dryer by the air dryer support bracket is defined as a support position P3.

[0040] In this case, the first connection position P1 may be the same as the support position P3 or may be a position farther from the frame 3 than the support position P3 in the vehicle width direction. In other words, the distance from the frame 3 to the first connection position P1 in the vehicle width direction may be equal to or greater than the distance from the frame 3 to the support position P3 in the vehicle width direction. For example, when the air dryer 5 is supported relative to the support portion 13b by fixing the base portion 22 on which the air dryer 5 is placed to the support portion 13b and fixing the metal band 23 wrapped around the air dryer 5 to the support portion 13b, the fixing position of the base portion 22 and the metal band 23 relative to the support portion 13b becomes the support position P3. In addition, when there are multiple support positions P3, the first connection position P1 may be the same as the support position P3 farthest from the frame 3 or may be a position farther from the frame 3 than the support position P3 farthest from the frame 3 in the vehicle width direction.

[0041] Furthermore, in the vehicle width direction, the second connection position P2 may be closer to the frame 3 than the first connection position P1. That is, the distance in the vehicle width direction from the frame 3 to the second connection position P2 may be less than the distance in the vehicle width direction from the frame 3 to the first connection position P1. In this case, the intermediate portion 15c may have a curved shape so as to approach the frame 3 from the air tank side fixing portion 15a toward the air dryer side fixing portion 15b when viewed from the vehicle up-down direction.

[0042] Thus, in the air dryer mounting structure 1 according to this embodiment, the restricting bracket 15 is connected to the air dryer support bracket 13 and the air tank support bracket 11B, thereby restricting movement of the air dryer support bracket 13 in the fore-and-aft direction of the vehicle relative to the air tank support bracket 11B. This makes it possible to properly support the air dryer 5 without increasing the rigidity of the air dryer support bracket 13 by making it more complex and larger. In this way, the provision of the restricting bracket 15 allows the air dryer support bracket 13 to have a simple configuration extending in the vehicle width direction, thereby suppressing increases in cost and weight and improving workability.

[0043] Furthermore, since the air tank support bracket 11B has higher rigidity in the vehicle front-rear direction than the air dryer support bracket 13, movement of the air dryer support bracket 13 in the vehicle front-rear direction can be effectively restricted.

[0044] Furthermore, the restricting bracket 15 allows the air dryer support bracket 13 to move relative to the air tank support bracket 11B in the vehicle up-down direction, thereby making it possible to suppress mutual influence between the vehicle up-down vibration of the air tanks 4,4 and the vehicle up-down vibration of the air dryer 5 when the vehicle 2 is subjected to vehicle up-down vibration from the traveling road surface. This makes it possible to suppress an increase in the vehicle up-down vibration of the air tanks 4,4 and the air dryer 5.

[0045] In addition, the intermediate portion 15c of the regulating bracket 15, which forms at least a part of the space between the air tank support bracket 11B and the air dryer support bracket 13 in the fore-and-aft direction of the vehicle, is formed into a plate shape extending in the fore-and-aft direction of the vehicle and in the vehicle width direction, thereby appropriately allowing movement of the air dryer support bracket 13 in the up-and-down direction of the vehicle relative to the air tank support bracket 11B.

[0046] In addition, in the vehicle width direction, the first connection position P1 between the regulating bracket 15 and the air dryer support bracket 13 is the same as the support position P3 of the air dryer 5 by the air dryer support bracket 13, or is farther from the frame 3 than the support position P3, so that movement of the air dryer support bracket 13 supporting the air dryer 5 in the fore-and-aft direction of the vehicle can be effectively regulated.

[0047] Incidentally, since the air tank support bracket 11B is fixed to the frame 3 and extends in the vehicle width direction, when vibrations in the vehicle front-rear direction are input to the vehicle 2, a force in the rotational direction about the fixed position with the frame 3 acts on the air tank support bracket 11B. Therefore, by positioning the second connection position between the regulating bracket and the air tank support bracket closer to the frame than the first connection position between the regulating bracket and the air dryer support bracket in the vehicle width direction, the force in the rotational direction about the fixed position with the frame 3 that is input to the air dryer support bracket 13 can be appropriately received by the regulating bracket 15 and the air tank support bracket 11B. This makes it possible to more effectively regulate deformation of the air dryer support bracket 13 in the vehicle front-rear direction.

[0048] Furthermore, since the air dryer 5 can be attached to the frame 3 by the fixing portion 13a and the support portion 13b of the air dryer support bracket 13, which are arranged in a substantially L-shape, the regulating bracket 15 can have a simple configuration. This makes it possible to further suppress increases in cost and weight and further improve workability.

[0049] In addition, since the support portion 13b of the air dryer support bracket 13 is formed in a plate shape extending in the vehicle width direction and the vehicle up-down direction, the support force of the air dryer 5 in the vehicle width direction and the vehicle up-down direction can be increased while the air dryer support bracket 13 has a simple structure, etc.

[0050] Furthermore, since the air tank support bracket 11B is formed to have a U-shaped cross section, the rigidity of the air tank support bracket 11B can be increased.

[0051] Although an embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and may be modified or applied to other things without departing from the gist of the claims.

[0052] For example, even if the air tank support bracket does not have higher rigidity in the fore-and-aft direction of the vehicle than the air dryer support bracket, the air dryer can be properly supported by the regulating bracket being connected to the air tank support bracket and the air dryer support bracket, so the air tank support bracket does not necessarily have to have higher rigidity in the fore-and-aft direction of the vehicle than the air dryer support bracket.

[0053] Similarly, even if the regulating bracket does not allow the air dryer support bracket to move in the vertical direction of the vehicle relative to the air tank support bracket, the air dryer can be properly supported by the regulating bracket being connected to the air tank support bracket and the air dryer support bracket, so the regulating bracket does not necessarily have to allow the air dryer support bracket to move in the vertical direction of the vehicle relative to the air tank support bracket.

[0054] Similarly, even if an auxiliary bracket is not provided, the air dryer can be properly supported by connecting the regulating bracket to the air tank support bracket and the air dryer support bracket, so an auxiliary bracket is not necessarily provided. [Explanation of symbols]
