JP 2010-120456 A

  In the conventional technique, welding is used when attaching a support member that supports the tension member to the inside of the upper surface portion of the bonnet. When the support member is welded to the inside of the upper surface portion of the bonnet, it is necessary to perform a finishing process such as buffing in order to remove welding distortion or the like at the welded portion. Furthermore, when the bonnet has a dent due to welding residual stress, a process for treating the bonnet dent has also been required. For this reason, when attaching a support member to the inner side of a bonnet, the man-hour increased and there was room for improvement.

  In view of the above situation, the present invention provides a bonnet structure for a work vehicle that can reduce the number of steps when attaching a support member that supports a tension member to the bonnet, and can appropriately attach the support member to the bonnet. With the goal.

A feature of the present invention according to claim 1 is provided with a bonnet configured to be able to switch between a closed posture and an open posture by swinging up and down.
Inside the bonnet, there is provided a tension member that can stand and support the bonnet in the open position, and a support member that swingably supports the tension member.
A double-sided adhesive member having a first adhesive surface bonded to the inner surface side of the bonnet and a second adhesive surface bonded to the support member side;
When the bonnet is in the closed position, a partition member that partitions the internal space of the bonnet into two spaces is provided,
The partition member is located inside the bonnet in the closed position so as to come into contact with the double-sided adhesive member from the second adhesive surface side.

  According to this characteristic configuration, when attaching the support member to the inner surface side of the bonnet, a double-sided adhesive member having a first adhesive surface bonded to the inner surface side of the bonnet and a second adhesive surface bonded to the support member side is used. The support member can be attached to the inside of the bonnet without welding. For this reason, the finishing process such as buffing as in the case of welding can be eliminated, and the number of man-hours can be reduced. And since a dent does not arise in a bonnet like the case of welding, the process of treating a dent does not arise. Therefore, the man-hour at the time of attaching a supporting member to the inner side of a bonnet can be reduced rather than the conventional case using welding etc.

  Moreover, a support member can be appropriately attached inside a bonnet by selecting what has sufficient adhesive force as a double-sided adhesive member. In addition, when the bonnet is in the closed position, the partition member comes into contact with the double-sided adhesive member from the second adhesive surface side, so that the double-sided adhesive member can be pressed inside the bonnet by this partitioning member. The adhesive state of the double-sided adhesive member can be appropriately maintained by pressing the member. Moreover, since the bonnet is normally in a closed position when the engine is operating, such as during traveling, even when the vibration of the engine is transmitted and the bonnet vibrates, the adhesive state of the double-sided adhesive member is pressed by the partition member. By holding this, it is possible to prevent the double-sided adhesive member from peeling off from the inside of the bonnet, and the support member can be appropriately attached to the inside of the bonnet.

  A feature of the present invention according to claim 2 is that the partition member has two spaces in the longitudinal direction of the vehicle body in an engine room that houses the engine and a rear side space when the bonnet is in the closed position. It is in the point comprised so that it may partition.

  According to this characteristic configuration, the internal space of the bonnet is partitioned into the engine room and the rear side space by the partition member, so that the rear side space can be hardly affected by the engine heat. As a result, devices and the like that are easily affected by heat can be accommodated in the rear side space, and therefore, by providing a partition member, arrangement of devices that can suppress the effects of heat on those devices and the like is performed. However, the support member can be appropriately attached to the inside of the bonnet.

  The feature of the present invention according to claim 3 resides in that an elastic member is provided at a contact portion of the partition member that contacts the second adhesive surface side of the double-sided adhesive member.

  According to this feature configuration, when the bonnet is in the closed position, the elastic member abuts on the second adhesive surface side of the double-sided adhesive member, so that even if the bonnet is repeatedly opened and closed, the double-sided adhesive member is unlikely to deteriorate. Further, since the elastic member is elastically deformed and abuts evenly with respect to the double-sided adhesive member, it becomes easy to apply a pressing force evenly to the entire double-sided adhesive member, and the adhesive state of the double-sided adhesive member can be appropriately maintained.

According to a fourth aspect of the present invention, when the bonnet is in the closed position, the partition member is in contact with the inside of the bonnet over the entire length in the lateral direction of the vehicle body. Configured to partition into space,
The said elastic member exists in the point provided over the full length of the site | part which contact | abuts the inner side of the said bonnet in the said partition member.

  According to this characteristic configuration, when the bonnet is in the closed position, the partition member comes into contact with the double-sided adhesive member and the bonnet via the elastic member provided over the entire length of the portion that contacts the inside of the bonnet. Yes. For this reason, the elastic member can reduce the transmission of vibration from the partition member to the bonnet while pressing the double-sided adhesive member, and can reduce the vibration of the bonnet.

  A feature of the present invention according to claim 5 is that the standing posture of the tension member is set to a posture in which the tension member pushes the support member against the inside of the bonnet.

  According to this characteristic configuration, when the bonnet is in the open posture, the tension force can be applied so as to press the support member against the inside of the hood with the tension member. Thereby, even when the bonnet is in the open posture, the adhesion state of the double-sided adhesive member can be appropriately maintained by the tension force of the tension member.

It is the whole tractor side view. It is a vertical side view of the vicinity of a bonnet when a bonnet is made into a closed posture. It is a vertical side view of the vicinity of the bonnet when the bonnet is in the open posture. It is a downward perspective view of the vicinity of a bonnet.
