Description

  The present invention relates to an entrainment prevention device installed in a transport vehicle such as a truck or a trailer.

  As shown in FIGS. 6 and 7, in a transport vehicle such as a truck or a trailer where the lower part of the vehicle side is not covered with a body panel, a pedestrian, a two-wheeled vehicle, and its passenger are involved when turning left or right due to an inner wheel difference. In order to avoid such a situation, a plate-shaped, saw-shaped, net-shaped, or bar-shaped side guard 1 is provided between the front and rear wheels 2 and 3 to form an entrainment prevention device.

  However, some transport vehicles have a box-shaped muffler 4 disposed in the lower part on the vehicle side. Where this type of muffler 4 is disposed, while avoiding the muffler 4, the body side or chassis Since it is difficult to adopt a structure in which the support arm is extended from the frame side to support the side guard, a muffler mounted on the outer side in the vehicle width direction of the muffler 4 for the purpose of protecting pedestrians and the like from the heat of the muffler 4 The cover 5 is used as a side guard.

  Further, as prior art document information related to this type of muffler cover, there is the following Patent Document 1.

Japanese Utility Model Publication No. 3-92519

  However, when substituting the muffler cover 5 as a side guard, the position of the muffler 4 may be too high depending on the vehicle type, and the ground clearance of the muffler cover 5 may exceed the legally stipulated value that can be recognized as a substitute for the side guard. In the case of a layout in which the muffler 4 is arranged behind the front wheel 2 as in the example shown here, the wheel 2 and the muffler 4 are too far apart and the muffler cover 5 and the wheel 2 In some cases, such a vehicle type needs to be redesigned to make the muffler cover 5 larger, and the distance between the two may exceed the legally stipulated value that can be accepted as a substitute for the side guard. The change of the muffler cover 5 that must be recreated from the beginning is very costly, and the muffler cover 5 is shared with the same muffler 4 between vehicles of different vehicle types. Cost of by will not be able was also large.

  The present invention has been made in view of the above circumstances, and even if the position of the muffler provided in the lower part on the vehicle side is too high or too far from the wheel, it is prevented from entrainment without incurring a significant cost increase. The object is to enable the apparatus to be configured.

The present invention is an entrainment prevention device for application to a vehicle having a muffler at a lower part on the vehicle side, and is attached to the outer side in the vehicle width direction of the muffler as a side guard so as to protect pedestrians and the like from heat. Further, the muffler cover is used as a substitute, and an auxiliary side guard that is detachably attached to the muffler and that is adjacent to the muffler cover so as to expand the entrainment prevention range.

  Thus, if this is done, the auxiliary side guard can be made adjacent to the muffler cover and the entrainment prevention range can be expanded simply by attaching the auxiliary side guard to the muffler as necessary. Even if the position of the muffler is too high or too far away from the wheel, it is not necessary to take measures such as making the muffler cover large and expanding the entrainment prevention range.

  In other words, it is cheaper to deal with the attachment and detachment of the auxiliary side guard that can be realized with simple parts than to deal with the change of the muffler cover, which increases the cost of the mold, and more car models can share the muffler cover. However, the cost will be greatly reduced.

  Furthermore, when carrying out the present invention more specifically, it is possible to use, for example, an auxiliary side guard that extends in the vehicle front-rear direction below the muffler cover. Even if it is too high and the ground clearance of the muffler cover exceeds the legally stipulated value that can be recognized as a substitute for the side guard, the auxiliary side guard expands the wrap-up prevention range downward and is legal. It is possible to satisfy various specified values.

  In addition, it is possible to use an auxiliary side guard that extends in the vertical direction on the side facing the wheel side of the muffler cover, and in this way, the wheel and the muffler are too far apart from each other. Even if the distance exceeds the legally stipulated value that can be recognized as a substitute for the side guard, the auxiliary side guard expands the wrap-up prevention range to the side facing the wheel side and is legal. The specified value can be satisfied.

  Furthermore, it is also possible to use an L-shaped auxiliary side guard that extends in the vehicle front-rear direction below the muffler cover and extends in the vertical direction on the side facing the wheel side of the muffler cover. If the ground clearance of the muffler cover and the distance to the wheel exceed the legally stipulated values that can be accepted as a substitute for the side guard, the auxiliary side guard will reduce the entanglement range downward and the wheel side. It becomes possible to expand to the side facing and meet legal regulations.

  It is also possible to use an auxiliary side guard that extends in the vehicle front-rear direction below the muffler cover and has an end facing the wheel side bent inward in the vehicle width direction to extend the required length. In the same way as described above, the auxiliary side guard can expand the entanglement prevention range downward to satisfy the legally prescribed value, and the end facing the wheel side can be bent inward in the vehicle width direction. By extending the required length, it is possible to prevent contact between the muddy rubber on the wheel side and the muffler, and it is possible to prevent damage to the muffler rubber muffler due to heat.

  According to the entrainment prevention device of the present invention described above, various excellent effects as described below can be obtained.

  (I) According to the invention described in claim 1 of the present invention, even if the position of the muffler provided in the lower part on the vehicle side is too high or too far from the wheel, the muffler cover is greatly reshaped and wound. Without taking measures to expand the prevention range, it is possible to expand the prevention range by satisfying the legal regulations by attaching the auxiliary side guard that can be realized with simple parts. The cost required for the vehicle can be remarkably reduced, and the cost can be significantly reduced by increasing the number of vehicle types that can share the muffler cover.

  (II) According to the invention described in claim 2 of the present invention, the position of the muffler is too high, and the ground clearance of the muffler cover exceeds a legally stipulated value that can be recognized as a substitute for the side guard. Even so, the auxiliary side guard can expand the entrainment prevention range downward to satisfy the legally prescribed value.

  (III) According to the invention described in claim 3 of the present invention, the distance between the muffler cover and the wheel exceeds the legal regulation value that can be recognized as a substitute for the side guard because the wheel and the muffler are too far apart. Even in such a case, it is possible to satisfy the legally prescribed value by expanding the entrainment prevention range to the side facing the wheel side by the auxiliary side guard.

  (IV) According to the invention described in claim 4 of the present invention, when both the ground clearance of the muffler cover and the distance to the wheels exceed a legally stipulated value that can be recognized as a substitute for the side guard, With the auxiliary side guard, the entrainment prevention range can be expanded downward and to the side facing the wheel side to satisfy the legally prescribed value.

  (V) According to the invention described in claim 5 of the present invention, in addition to the effect of (II) above, the end facing the wheel side is bent inward in the vehicle width direction to extend the required length, Contact between the muddy rubber on the wheel side and the muffler can be prevented, and damage to the muddy rubber muffler due to heat can be prevented.

It is a perspective view which shows the example of 1st form of this invention. It is sectional drawing of the II-II arrow of FIG. It is a perspective view which shows the example of a 2nd form of this invention. It is a perspective view which shows the example of a 3rd form of this invention. It is a perspective view which shows the 4th example of a form of this invention. It is the schematic which shows an example of the conventional wrapping prevention apparatus. It is a perspective view which expands and shows the principal part of FIG.

  Embodiments of the present invention will be described below with reference to the drawings.

  1 and 2 show a first embodiment of the wrapping prevention apparatus according to the present invention, and the same reference numerals as those in FIGS. 6 and 7 denote the same components.

In the example shown here, a muffler 4 is provided behind the front wheel 2 in the lower part of the vehicle side, as in the case of the conventional example of FIG. The muffler cover 5 which protects a pedestrian etc. from heat and is substituted also as a side guard is attached via the bracket 6 (refer FIG. 2).

  Here, as shown in detail in FIG. 2 in particular, the bracket 6 has a hat-shaped cross section at the top and supports the muffler cover 5 at a slight distance from the outer surface in the vehicle width direction of the muffler 4. In addition, a mounting seat 7 that forms a horizontal plane at the lowermost end portion is formed by bending the lower portion thereof downward inward in the vehicle width direction.

  An auxiliary side guard 8A extending in the vehicle front-rear direction below the muffler cover 5 is fastened to the mounting seat 7 with a bolt 10 and a nut 11 via a support member 9. The guard 8A is adjacent to the lower portion of the muffler cover 5 so that the wrap-up prevention range is expanded downward.

  Thus, if this is done, the auxiliary side guard 8A is simply attached to the mounting seat 7 of the muffler 4 as necessary, and the auxiliary side guard 8A is adjacent to the lower part of the muffler cover 5 to increase the wrapping prevention range. Even if the position of the muffler 4 is too high and the ground clearance of the muffler cover 5 exceeds the legally stipulated value that can be recognized as a substitute for the side guard, it is possible to expand downward. The auxiliary side guard 8A makes it possible to expand the entrainment prevention range downward to satisfy the legally prescribed value, and it is not necessary to take measures such as making the muffler cover 5 larger and expanding the entrainment prevention range. .

  That is, it is cheaper to deal with the attachment / detachment of the auxiliary side guard 8A that can be realized with simple parts than the case of dealing with the change of the muffler cover 5 that is expensive to mold, and the vehicle type that can share the muffler cover 5 Increasing the cost can significantly reduce costs.

  Therefore, according to the above-described embodiment, even if the position of the muffler 4 is too high and the ground clearance of the muffler cover 5 exceeds the legally stipulated value that can be recognized as a substitute for the side guard, the muffler Instead of taking measures to expand the cover prevention range by making the cover 5 larger, the auxiliary cover guard 8A that can be realized with simple parts can be installed to expand the cover prevention range and meet legal regulations. Therefore, the cost required for the implementation can be remarkably reduced, and the cost can be significantly reduced by increasing the number of vehicle types that can share the muffler cover 5.

  FIG. 3 shows a second embodiment of the present invention. The auxiliary side guard 8A that extends in the vehicle front-rear direction below the muffler cover 5 in FIG. The auxiliary side guard 8B extends in the vertical direction on the side facing the wheel 2 side, and is not particularly shown here, but the mounting seat 7 in this case is disposed at a different position on the wheel 2 side. Of course, it is supposed to be done.

  Thus, if this is done, the wheel 2 and the muffler 4 will be too far apart so that the distance between the muffler cover 5 and the wheel 2 exceeds the legally stipulated value that can be recognized as a substitute for the side guard. Even in such a case, the auxiliary side guard 8B can expand the entrainment prevention range to the side facing the wheel 2 to satisfy the legally prescribed value.

  FIG. 4 shows a third embodiment of the present invention, which extends in the vehicle front-rear direction below the muffler cover 5 and extends in the vertical direction on the side facing the wheel 2 side of the muffler cover 5. This is an example using the auxiliary side guard 8C bent in an L shape so that both the ground height of the muffler cover 5 and the distance to the wheel 2 can be recognized as a substitute for the side guard. If the specified value exceeds the specified value, the auxiliary side guard 8C can expand the wrapping prevention range downward and to the side facing the wheel 2 to satisfy the legal specified value.

  FIG. 5 shows a fourth embodiment of the present invention. An end portion extending in the vehicle front-rear direction below the muffler cover 5 and facing the wheel 2 side is bent inward in the vehicle width direction to have a required length. In this example, the extended auxiliary side guard 8D is used. In this way, as in the case of the first embodiment described above, the auxiliary side guard 8D expands the entrainment prevention range downward and is regulated by law. In addition to satisfying the value, the end facing the wheel 2 side is bent inward in the vehicle width direction to extend the required length, so that the mudguard rubber 12 on the wheel 2 side (see FIG. 1) and the muffler 4 Can be prevented, and the muffler 4 of the mudguard rubber 12 can be prevented from being damaged by heat.

  In addition, the entrainment prevention device of the present invention is not limited to the above-described embodiment, and the auxiliary side guard may have a shape other than that illustrated in FIG. Although an example in which a mounting seat is formed on a bracket for mounting a muffler cover to the muffler is shown, a mounting seat may be provided directly on the lower surface of the muffler, and other aspects do not depart from the gist of the present invention. Of course, various changes can be made within the range.
