Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to a vibration isolating device for a truck wing body.

(Prior Art) In recent years, some trucks have been put into practical use by attaching a wing body to the chassis to enable pallet transportation.

This wing body, as shown in Figure 1,
A canopy roof 4 is installed between the front plate 2 and rear plate 3 provided on the loading platform chassis 1, and can be opened upwards using the central part in the width direction of the loading platform as a fulcrum. The open end edge of the canopy roof 4 can be placed on the upper edge of the side flap plate 5 or on the cargo chassis 1 and closed.

By the way, as shown in FIG. 2, the canopy roof 4 of the wing body has a front upright plate 2 and a rear upright plate 3 attached to it via a shaft (not shown) inserted through its base end. It is hinged to the torii frames 2a and 3a and supported rotatably, but in such a support structure, the open end of the canopy roof 4 is
Since it is in a free state with respect to the rear upright plates 2 and 3, the inertial force generated when the truck starts or brakes causes distortion in the longitudinal direction as shown in Fig. 3, and as a result, When the above inertia occurs, vibrations occur in the longitudinal direction, resulting in a so-called flapping phenomenon, resulting in poor ride comfort for the occupants.

This drawback has become noticeable because in recent years, roofs have been increasingly made of aluminum in order to reduce vehicle weight.

(Purpose) This invention was made in view of the above, and
The object is to provide a vibration isolator for a wing body that can eliminate the above-mentioned drawbacks.

(Structure) The present invention locks the front and rear ends of the open end of the canopy roof plate, which is the main part of the wing body, on the loading platform chassis side when the roof plate is closed, and Reinforcing aggregate is fixed to the inner surface to increase the rigidity of the roof board.

Hereinafter, the present invention will be explained with reference to the illustrated embodiments.

In FIG. 4, the same members as those shown in FIGS. 1 to 3 are given the same reference numerals.

In FIG. 4, the canopy roof plate 4 has a cross section L that is divided into left and right directions with the central part in the width direction of the loading platform as the border.
It is shaped like this and is swingable via a support shaft (not shown) located at the center of the upper plate.

The length in the longitudinal direction of this canopy roof plate 4 is the same as that of the torii frame 2 fixed at the front and rear of the loading platform chassis 1.
The length is set to include the thickness in the longitudinal direction of the loading platform of the torii frames 2a and 3a, and therefore, when the canopy roof plate 4 is closed, the top plate part and the side plate part are
It is designed to cover a.

Each front and rear torii frame 2 in the side plate part of the canopy roof board 4
Engagement pins 5 and 6 are fixed to the inner surface of the torii frames 2a and 3a at two locations, upper and lower, corresponding to the engagement pins 5 and 6. , 6 are engaged with locking grooves 21, 22 (front torii frame) and 31, 32 (rear torii frame).

As shown in FIG. 5, the locking grooves 21, 22, 31, 32 have a substantially triangular cross-sectional shape that opens downwardly inside the torii frames 2a, 3a. When the roof shingle 4 swings, the engagement pins 5 and 6 are smoothly engaged without hitting the surfaces of the torii frames 2a and 3a, and without lifting the inner surfaces of the roof shingles from the frames. I'm starting to be able to get out of it.

The above-mentioned engagement pins 5 and 6 are provided on a reinforcing member 7, which is an aggregate and is fixed to the inner surface of the canopy roof plate 4.

This reinforcing member 7 is provided between engagement pins arranged at two locations above and below the front and rear ends of the roof board 4 in the longitudinal direction.
The reinforcing members 7 are diagonally fixed to the inner surface of the roof board 4, and engagement pins 5 and 6 are fixed to the front and rear portions of the diagonal reinforcing members 7.

The reason why the reinforcing members 7 are arranged diagonally is to increase the rigidity of the canopy roof 4 in the longitudinal direction and in the vertical direction of the side panels.

Note that the above-mentioned engagement pin of the roof board is in an engagement relationship by fitting into the locking groove of the torii frame, but instead of this, a mechanism for gripping the locking pin, such as a ball catch (product name) etc. By using this, it is possible to prevent the open end of the roof plate 4 from accidentally jumping up.

(Effects) According to the present invention, when the canopy roof plate is closed, the front and rear parts of the open end in the longitudinal direction can be locked by the torii frame, so the open end of the roof plate can be viewed from the loading platform chassis side. Therefore, when the truck starts or brakes, it is possible to prevent vibrations due to the inertial force in the longitudinal direction of the roof plate that acts on the roof plate, and also to prevent the roof plate from deforming due to this inertial force. This can be suppressed by the reinforcing member on the inner surface of the roof plate, and as a result, the riding comfort for the occupants can be improved.
