Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of an intercooler mounting device for mounting an intercooler for cooling intake air supercharged by a turbocharger on the front surface of a vehicle radiator, for example, to a vehicle frame.

[0002]

[Prior Art]

 The intercooler consists of an upper tank and a lower tank that are respectively connected to the discharge port of the turbocharger and the intake port of the engine, and a plurality of heat dissipation tubes connected between the upper tank and the lower tank. Are directly or indirectly attached to the frame by screwing attachment pieces on both sides of the upper tank and the lower tank to a pair of supports fixed to a vehicle frame or a bracket attached to the frame. This screwing is done by tightening the mounting pieces of both tanks with mounting bolts and nuts that penetrate these mounting pieces and the support.

[0003]

[Problems to be solved by the device]

 The intercooler is repeatedly subjected to thermal expansion and contraction due to the hot air flowing in its heat dissipation tube and its cooling, but both tanks of the intercooler fix their mounting pieces to the support by screwing. Mechanically restrained, while the support is exposed to the outside air and is not subject to temperature changes, there is a risk that a large load will be applied to the base of the heat dissipation tube during thermal expansion, resulting in damage.

An object of the present invention is to provide an intercooler mounting device that avoids the above-mentioned drawbacks, does not apply a high load to a heat dissipation tube of the intercooler, and can effectively prevent damage to the intercooler. It is in.

[0005]

[Means for Solving the Problems] In order to solve the above problems, the present invention provides an upper tank and a lower tank that are connected to a discharge port of a turbocharger and an intake port of an engine and between the upper tank and the lower tank. The mounting pieces on both sides of the upper tank and the lower tank of the intercooler, which consist of a plurality of heat radiation tubes installed in the vehicle, penetrate the mounting pieces and the supports into a pair of supports fixed directly or indirectly to the vehicle frame. An inner cooler mounting device that mounts the upper tank and the lower tank on the support by tightening the mounting bolts and nuts, and includes an elastic ring interposed between the inner peripheral surface of the bolt through hole of the mounting piece and the mounting bolt. The collar that receives the tightening force is placed between the head and the nut of the And to provide a Ntakura mounting device.

[0006]

[Action]

 In this way, when an elastic ring is interposed between the inner surface of the bolt through hole of the mounting pieces of the upper and lower tanks of the intercooler and the mounting bolt, the upper and lower tanks are restrained with respect to the support. Since it can be mounted movably to some extent without any load, when the heat dissipation tube thermally expands and contracts and a load is applied to the upper and lower tanks, this load is absorbed by the elastic ring, so no load is applied to the base of the heat dissipation tube. . In addition, since the collar that receives the tightening force is placed between the head of the mounting bolt and the nut, the load absorbing function of the elastic ring is not impaired by the surface pressure caused by tightening the mounting bolt, and The load during thermal expansion and contraction can be reliably absorbed and damage to the intercooler can be reliably prevented.

【Example】

 1 and 2 show an intercooler mounting device 10 according to the present invention, and an intercooler 12 to be mounted according to the present invention is a turbocharger (not shown). An upper tank 16 that is piped from the discharge port of the engine, a lower tank 18 that is piped to the intake port of the engine, and an interlacer main body 22 including a plurality of heat dissipation tubes 20 provided between the upper tank 16 and the lower tank 18. Made of. The high temperature air supplied from the turbocharger to the upper tank 16 is cooled while descending the heat radiation tube 20, and supplied from the lower tank 18 to the intake port of the engine.

As can be seen from FIG. 1, the intercooler mounting device 10 includes a pair of supports 28 having a U-shaped cross section, which are supported by a pair of chassis frames 24, 24 ′ of a vehicle through cushions 26, 26 ′. 28 ′, and the front and rear mounting pieces 30, 30 ′ on both sides of the upper tank 16 and the lower tank 18 of the intercooler 12, as will be described later in detail with reference to FIGS. , 28 'are attached to the front and rear flanges 28a, 28'a by mounting bolts 32, 32'.

As can be seen from FIGS. 3 and 4, the supports 28, 28 ′ and the mounting pieces 30, 30 ′ are bolt through holes 28 b, 28 ′ b and 30 a, 30 ′ through which the mounting bolts 32, 32 ′ pass. a in alignment, the mounting bolts 32, 32 'pass through these bolt through holes 28b, 28'b and 30a, 30'a via collars 34, 34' to provide mounting bolts 32, 32 '. The nuts 36 and 36 'are screwed to the threaded portions where "' projects from the mounting pieces 30 and 30 ', and the upper and lower tanks 16 and 18 are fixed to the supports 28 and 28'.

As shown in FIG. 3 and FIG. 4, the intercooler mounting device 10 of the present invention has an inner circumference of the bolt through holes 30a, 30'a of the left and right mounting pieces 30, 30 'of both tanks 16,18. It is provided with a rubber elastic ring 38, 38 'interposed between the surface and the mounting bolts 32, 32'. In the illustrated embodiment, the elastic rings 38, 38 'are enlarged portions 30b, 30' formed in the bolt through holes 30a, 30'a on the head portions 32a, 32'a side of the mounting bolts 32, 32 '. The portion of the bolt through holes 30a, 30'a other than the enlarged portions 30b, 30'b has a play with respect to the collars 34, 34 '. The collars 34, 34 'are arranged to receive the tightening forces of the heads 32a, 32'a of the mounting bolts 32, 32' and the nuts 36, 36 '.

As described above, there is elasticity between the mounting bolts 32, 32 ′ and the inner peripheral surfaces of the bolt through holes 30 a, 30 ′ of the mounting pieces 30, 30 ′ of the upper and lower tanks 16, 18 of the intercooler 12. By interposing the rings 38, 38 ', the upper and lower tanks 16, 18 are movably movable within the elastic deformation of the elastic rings 38, 38' without being restrained by the supports 28, 28 '. Mounted. Therefore, when the heat radiating tube 20 of the intercooler main body 22 is thermally expanded and contracted and a load is applied to the upper and lower tanks 16 and 18, this load is effectively absorbed by the elastic rings 38 and 38 '. Therefore, the heat-releasing tube 20 does not have a load applied to the root portions connected to the upper and lower tanks 16 and 18 due to the thermal expansion and contraction.

Further, since the collars 34, 34 'receive the tightening force between the heads 32a, 32'a of the mounting bolts 32, 32' and the nuts 36, 36 ', the tightening by the mounting bolts 32, 32' is performed. It is possible to reliably absorb the load when the heat radiating tube 20 expands and contracts, without impairing the load absorbing action of the elastic rings 38 and 38 'due to the surface pressure.

[0013]

[Effect of the device]

 According to the present invention, as described above, since the elastic ring is interposed between the inner peripheral surface of the bolt through holes of the mounting pieces of the upper and lower tanks of the intercooler and the mounting bolt, both of these upper and lower tanks are attached. Since the tank is movably attached to the support without being constrained, the heat dissipation tube of the intercooler body expands and contracts thermally, and the load on the upper and lower tanks is absorbed by this elastic ring. No load is applied to the parts and damage to the intercooler can be prevented. In addition, since the collar that receives the tightening force is placed between the head of the mounting bolt and the nut, the load absorption function of the elastic ring is not affected by the surface pressure caused by tightening the mounting bolt, and the heat dissipation tube The load at the time of heat expansion and contraction can be reliably absorbed, and damage to the intercooler can be reliably prevented.
