Description

  The present invention relates to a cover disposed on the front surface of an intercooler in order to protect fins and the like of the intercooler.

  Conventionally, in a vehicle equipped with a supercharger such as a turbocharger, an intercooler is installed to cool the air whose temperature has been increased by the supercharger. For example, in the case of a front engine vehicle, the intercooler is placed in front of the engine room or placed above the engine. In addition, there are air-cooled and water-cooled intercoolers.

  When an air-cooled intercooler is arranged above the engine, depending on the vehicle, an intake port called an air intake that guides cooling air (air) for cooling fins for heat dissipation of the intercooler is formed in the bonnet. . While the vehicle is running, the cooling air is guided from the air intake into the bonnet, so that the air efficiently hits the intercooler.

  In a vehicle having such a structure, pebbles or the like may jump in from the air intake during traveling, and may collide with the fins of the intercooler and damage the fins. For this reason, in order to protect a fin, the front surface of an intercooler may be protected with a breathable cover (for example, refer to patent documents 1).

  However, when the cover of the intercooler is fixed with bolts or the like, the cover cannot be easily removed when the engine room is inspected.

  ADVANTAGE OF THE INVENTION According to this invention, the protective cover of the intercooler which can be removed easily can be provided.

It is the top view which looked at the protective cover of embodiment from the upper direction. It is the simplified sectional view of the engine room in the state where the protection cover of the embodiment was attached to the intercooler. It is the figure which looked at the protective cover and intercooler of embodiment from the arrow A direction of FIG. It is a figure explaining the slide position of the holding plate of the protective cover of embodiment.

  Hereinafter, embodiments of a protective cover for an intercooler will be described with reference to the drawings.

  FIG. 1 is a plan view of the protective cover 1 for the intercooler 50 according to the present embodiment as viewed from above. FIG. 2 is a diagram showing a state where the protective cover 1 is attached to the intercooler 50, and is a simplified cross-sectional view when the inside of the engine room is viewed from the side. FIG. 3 is a view of the protective cover 1 of the present embodiment attached to the intercooler 50 as viewed from the front (in the direction of arrow A in FIG. 2). In FIG. 3, only the protective cover 1 and the intercooler 50 are shown.

  The protective cover 1 of the present embodiment protects the intercooler 50 from pebbles and the like that jump from an air intake that is an opening formed in the bonnet. The protective cover 1 can prevent the entry of objects such as pebbles while ensuring the inflow of air (cooling air) flowing from the air intake that is cooled by heat exchange with the fins. And the protective cover 1 of this embodiment can be easily attached or detached with respect to the intercooler 50, for example, when opening a bonnet and showing an engine room etc., the protective cover 1 can be removed quickly. For example, when traveling on a normal road or the like, the protective cover 1 is attached to prevent entry of pebbles, etc., but traveling at a higher load than usual, such as when traveling at high speed in places where there are few pebbles such as circuits. Therefore, the protective cover 1 can be easily removed when it is desired to remove the protective cover and increase the efficiency of air flow into the intercooler. And when attaching after removing, it can attach easily.

  In the present embodiment, as shown in FIG. 2, a case where the intercooler 50 to which the protective cover 1 is attached is placed horizontally above the engine 60 will be described. In the present embodiment, cooling air is taken in from air intakes, which are openings formed in the bonnets 70 and 72, and the cooling air is passed through the heat dissipating fins of the intercooler 50 placed horizontally to be compressed by the supercharger. Cool the rising air. In the present embodiment, the protective cover 1 is disposed on the upper portion (front surface) of the intercooler 50 that is upstream of the flow of cooling air from the air intake with respect to the intercooler 50.

  As shown in FIG. 3, the protective cover 1 of the present embodiment includes a frame portion 54 around a core portion 52 in which an intercooler 50 is configured by a passage through which air from a supercharger or a fin passes, and the frame portion. It is possible to use the intercooler 50 of the type having the outer edge portions 54a protruding from the upper end (end portion on the front surface side) 54 to both sides in the longitudinal direction of the intercooler 50. However, the position of the outer edge portion 54a is not limited to the positions on both sides in the longitudinal direction of the intercooler. For example, when an outer edge portion is formed on the outer side from the front side end portion in the short direction of the intercooler, the fixing means for the protective cover 1 of the present embodiment may be provided in accordance with the position of the outer edge portion. . That is, if the fixing means of the protective cover 1 of this embodiment is provided in accordance with the position where the outer edge portion 54a is formed, the protective cover 1 can be fixed to the intercooler easily and detachably.

  Further, FIG. 2 shows a part of an air intake formed, for example, in the vicinity of the center of the bonnet in order to guide the cooling air to the intercooler 50. In the air intake, for example, resin ducts 74 and 76 are connected in the bonnet, and the cooling air is guided to the intercooler 50 by the ducts 74 and 76. A duct 74 is connected to a bonnet 70 extending from the front side of the vehicle, and a duct 76 is attached to the inside of a bonnet 72 above the air intake. Note that the duct 74 and the duct 76 are cylindrical members connected to the air intake.

  The protective cover 1 of the present embodiment includes a frame 2, a net 4 that is a net-like member, a quick release 6 that is a lever portion, a holding plate 8 that is a holding member, and the like.

  The frame 2 is a frame body of the protective cover 1 and is a member that holds the net 4. The frame 2 has a shape that matches the shape of the surface on which the protective cover 1 of the intercooler 50 is mounted. In the present embodiment, the frame 2 has a rectangular shape. The frame 2 has an opening 2b, and the net 4 is attached to a range including the opening 2b.

  Extending portions 2 a are formed at both end portions in the longitudinal direction of the frame 2. The extension portion 2a is formed with a hole through which a shaft for fastening the quick release 6 (bolt 64e in the present embodiment) is passed, and the quick release 6 is attached.

  The frame 2 includes bent portions 2c that are bent upward on the upstream side in the flow direction of the cooling air on both sides in the front-rear direction of the vehicle in a state where the frame 2 is mounted on the intercooler 50 of the vehicle. In the present embodiment, the bent portion 2c is formed by a net 4 of the protective cover 1 in which the end portions (that is, the long side portion of the frame 2) on both sides in the short direction (vehicle longitudinal direction) of the protective cover 1 are parallel to the front surface of the intercooler 50. The cover surface is bent upward (the side on which the lever 6a of the quick release 6 is disposed) and is bent. The bent portion 2c is formed from one end of the long side of the protective cover 1 to the other end. The presence of the bent portion 2c makes it difficult for the frame 2 to bend. In addition, kinking can be prevented by the bent portion 2c. Therefore, the strength of the protective cover 1 is improved by the bent portion 2c. Further, the air flowing through the bent portion 2c can be guided to the opening 2b through which the air of the protective cover 1 can pass, and the efficiency of cooling the intercooler 50 can be increased.

  Furthermore, as shown in FIG. 2, the protective cover 1 is prevented from being displaced from the intercooler 50 by being formed so that the upper surface side of the bent portion 2 c is pressed against the tip portions 74 a and 76 a of the ducts 74 and 76. it can. In particular, in this embodiment, the front end portion 74a presses the protective cover 1 so as not to move backward, and the front end portion 76a holds the protective cover 1 so as not to move forward. Therefore, the movement of the protective cover 1 in the vehicle front-rear direction can be more reliably prevented. Further, since the bent portion 2c is in contact with the end portions 74a and 76a of the ducts 74 and 76, an effect that the air flowing through the ducts 74 and 76 is more easily guided to the intercooler 50 is obtained, and the cooling efficiency of the intercooler 50 is obtained. Will improve.

  The angle at which the bent portion 2c is bent and the width of the bent portion 2c in the vehicle front-rear direction are not particularly limited. It is sufficient that the bent portion 2c is formed by being bent with such a width that the tip portions 74a and 76a can contact each other. In a case where the protective cover 1 is pressed by the ducts 74 and 76, it is only necessary that the tip portions 74a and 76a be bent to such an extent that a force that prevents the protective cover 1 from moving in the front-rear direction comes into contact with the bent portion 2c.

  The frame 2 is preferably made of metal so as to have a strength that does not cause deformation due to a collision of pebbles or the like, vibration of the vehicle, or the like, and can withstand heat from an engine or the like.

  The net 4 is mounted so as to cover the entire opening 2b of the frame 2, and allows the inflow of air and prevents the entry of objects such as pebbles. It is preferable that the net 4 has a strength that does not cause breakage even when pebbles collide. For example, a net (mesh) made of metal such as a metal net is preferable. The shape of the mesh of the mesh 4 is not particularly limited, and a plain woven quadrangular shape or a honeycomb hexagonal shape can be used. The net 4 may be any material having air permeability, and may be a punching metal or the like. The size of the mesh may be a size that does not hinder the inflow of air while preventing entry of pebbles and the like. Although the net | network 4 should just cover the whole opening part 2b at least, in this embodiment, it is attached to the range shown by the broken line of FIG. 1, ie, the rectangular range except the extension part 2a of the flame | frame 2. FIG.

  The quick release 6 is a means for making the protective cover 1 easily detachable from the intercooler 50. The quick release 6 includes a lever 6a, an eccentric cam portion 6b that is an eccentric cam, washers 6c and 6d, and a bolt 6e that is a fastening shaft member. The washers 6c and 6d may be arranged as necessary.

  The eccentric cam portion 6b is an eccentric cam. Specifically, the rotation shaft on which the eccentric cam portion 6b having a true outer diameter rotates is at a position shifted from the center of the eccentric cam portion 6b, and the center of the eccentric cam portion 6b is the center of rotation. It is off. As a result, the eccentric cam portion 6b functions as an eccentric cam. When the lever 6a is tilted by the eccentric cam portion 6b, the bolt 6e is pushed up, and a clamping force is generated between the cam portion 6b and the seat surface of the bolt 6e. When the lever 6a is raised, the bolt 6e is released and the clamping force is loosened.

  In FIG. 2, as an example, the position where the lever 6a shown by the solid line is tilted is the fixed position of the quick release 6 where the clamping force is generated, and the position where the lever 6a is raised from the fixed position (for example, shown by the broken line) Position) is the release position of the quick release 6 where the clamping force is released. In this manner, the attachment / detachment state of the protective cover 1 to the intercooler 50 can be switched by tilting or raising the lever 6a.

  The shape of the lever 6a shown in FIG. 2 is an example. The lever 6a is a rod or plate that extends from the eccentric cam portion 6b, and may have any form and shape as long as the eccentric cam portion 6b can be rotated. Further, the fastening shaft member is not limited to the bolt 6e, and is constituted by a shaft portion screwed into the eccentric cam portion 6b and a member attached to the shaft portion or formed on the shaft portion and having a seat surface that generates a clamping force. Anything can be used. For example, the tightening shaft member may be a shaft and a nut.

  The holding plate 8 is disposed at a position facing the eccentric cam portion 6 b of the quick release 6 with the frame 2 interposed therebetween. When the lever 6a is tilted, the holding plate 8 is pushed up by the seating surface of the bolt 6e, and a clamping force is generated between the eccentric cam portion 6b and the holding plate 8. The protective cover 1 is fixed to the front surface (upper part) of the intercooler 50 by sandwiching the frame 2 and the outer edge portion 54 a of the intercooler 50 by the quick release 6 and the holding plate 8.

  As shown in FIGS. 1 and 4, the holding plate 8 of the present embodiment is a strip-like plate that is long in the short direction of the protective cover 1 (long along the outer edge portion 54 a of the intercooler 50). In the present embodiment, the holding plate 8 is formed in the same size and shape as the extending portion 2 a of the frame 2. When the holding plate 8 is long (has a longitudinal direction) along the outer edge portion 54a, the holding plate 8 comes into contact along the outer edge portion 54a of the intercooler 50, so that the contact area with the outer edge portion 54a is widened. As a result, when the quick release 6 clamps the frame 2 and the outer edge portion 54a of the intercooler 50, the clamping force acts more widely than when the head of the bolt 6e or the washer 6d contacts the outer edge portion 54a. The protective cover 1 can be fixed to the intercooler 50.

  A long hole 8 a that is long in the short direction of the holding plate 8 is formed near the center of the holding plate 8. The shaft of the bolt 6e of the quick release 6 is passed through the long hole 8a. When the lever 6a of the quick release 6 is in the release position and the clamping force is released, the holding plate 8 can be guided and slid by the shaft of the bolt 6e.

  FIG. 4 is a diagram for explaining the slide position of the holding plate 8. FIG. 4A is a view showing a state where the holding plate 8 is in the first position moved to the intercooler 50 side. FIG. 4B is a view showing a state in which the holding plate 8 is in the second position pulled out to the side away from the intercooler 50. The holding plate 8 can move within the range of the position (a) and the position (b), with the long hole 8a guided by the shaft of the bolt 6e.

  4A, the holding plate 8 is inserted under the outer edge portion 54a of the intercooler 50, and the holding plate 8 overlaps with the outer edge portion 54a in a plan view in the Z-axis direction (viewed in the axial direction of the bolt 6e). It will be in the state. By setting the quick release 6 to the fixed position in the state of (a), the outer edge portion 54a and the frame 2 are clamped by the holding plate 8 and the quick release 6, and the protective cover 1 is fixed. At the position of FIG. 4B, the holding plate 8 moves to the outside not overlapping with the outer edge portion 54a in plan view. Since the holding plate 8 does not overlap with the outer edge portion 54a, the protective cover 1 can be easily detached from the intercooler 50 by lifting the protective cover 1 upward (Z-axis direction). In the case of wearing, the reverse procedure is performed.

  Furthermore, the holding plate 8 of the present embodiment has protruding portions 8b that protrude on both sides of the protective cover 1 in the short side direction (longitudinal direction of the holding plate 8, X-axis direction) at the intercooler 50 side. The protrusion 8b formed at the end on the intercooler 50 side widens the width of the holding plate 8 and widens the contact area with the outer edge portion 54a of the intercooler 50. By expanding the contact area with the outer edge portion 54a, the protective cover 1 can be more stably fixed to the intercooler 50 when the quick release 6 is set to the fixed position.

  In the drawing, the holding plate 8 is shown as a flat plate without bending. Actually, when the quick release 6 is in a fixed state, the portion of the holding plate 8 through which the bolt 6e passes is lifted to the cam 6b side by the clamping force of the quick release 6 and approaches the extended portion 2a of the frame 2 or In close contact. On the other hand, the part which overlaps with the outer edge part 54a of the holding plate 8, the net | network 4, etc. will be in the state expanded by the thickness. Therefore, when the quick release 6 is set to the fixed position, the outer edge portion 54a, the frame 2 and the like are clamped together with the cam portion 6c while the holding plate 8 is bent obliquely. If the mesh 4 is attached to the range where it overlaps with the holding plate 8 in a state where the holding plate 8 is inserted in the position of FIG. 4A, the holding plate 8 is bent by the thickness of the mesh 4 and the clamping force is increased. Since this occurs, the protective cover 8 can be fixed to the intercooler 50 more strongly.

  According to the protective cover 1 of this embodiment described above, the protective cover 1 that can be easily attached to and detached from the intercooler 50 can be provided. In addition, the protective cover can be more securely fixed to the intercooler by having the protruding portion 8b so that the contact area is wider at the portion where the holding plate 8 is sandwiched. In addition, since the frame 2 has the bent portions 2c in contact with the end portions 74a and 76a of the ducts 74 and 76, the cooling air can be efficiently introduced into the intercooler 50. Further, the bent portion 2c is pressed by the tip portions 74a and 76a, so that the protective cover 1 is prevented from being displaced from the intercooler 50 during traveling of the vehicle, and the protective cover 1 can be more reliably fixed.

  In this embodiment, although the protective cover 1 was demonstrated as arrange | positioning in the front surface of the intercooler 50 arrange | positioned horizontally on the engine 60, it is not restricted to this. It may be mounted on an intercooler that is disposed at an inclination, or may be mounted on an intercooler that is disposed in front of the engine room.

  In the present embodiment, the holding plate 8 has a shape having the protruding portion 8b. However, the shape is not limited to this, and the holding plate 8 has a long hole 8a, and the holding plate 8 is inserted as shown in FIG. What is necessary is just to be a shape and a magnitude | size which can clamp the outer edge part 54a of the intercooler 50 when the quick release 6 is made into a fixed position. For example, a rectangle without the protrusion 8b may be used. Moreover, the net | network 4 may be arrange | positioned at the front side of the flame | frame 2, and may be fixed to the edge of the opening part 2b.
