Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for mounting a truck on a body frame of a truck.

[0002]

2. Description of the Related Art Conventionally, a truck bed or an aluminum van is mounted on a vehicle body frame, for example, in the case of an aluminum van, as shown in FIG. A vertical joist 52 is provided along both sides of the aluminum van in the vertical direction, and a plurality of U-bolts 54 are attached to a body frame 53 provided beneath the vertical joist 52.
Is fixed integrally.

[0003]

However, with the above-mentioned conventional mounting, the vehicle is bent or twisted while traveling on an extremely rough road.
Acts on the body frame and the carrier or aluminum van attached to the body frame as an integral structure.For example, in the case of an aluminum van, the load of luggage that is relatively weak against bending or twisting of the vehicle It is considered that stress concentrates on a right-angle cut portion of a component such as an outlet and causes fatigue fracture of the member, and a crack 55 is generated at a location shown in FIG.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and has an effect of interfering with displacements such as "bending" and "twisting" which occur repeatedly during rough road running of a body frame on which a loading platform or an aluminum van is mounted. It is another object of the present invention to provide a vehicular luggage mounting apparatus that does not directly affect the mounted luggage or aluminum van.

[0005] To this end, the conventional method of fixing the vehicle carrier to the vehicle body frame is stopped, and "bending" and "twisting" of the vehicle body frame induced according to the situation on the traveling path and the traveling state of the vehicle are eliminated. A point-like connecting part that connects the body frame and the vehicle carrier is provided at the position where the displacement is offset, and the other parts are cut off from the body frame so as to absorb the displacement via the cushioning member and not be affected. There is a need to.

[0006]

SUMMARY OF THE INVENTION In view of the above, the present invention provides an apparatus for mounting a luggage carrier for a vehicle in a device for mounting a luggage carrier on a body frame of a truck. And a receiving portion that absorbs displacement between the carrier and the body frame between the carrier and the body frame in a portion radially extended in four directions with the swing coupling portion substantially as a center. Features.

[0007]

According to the construction of the first aspect of the present invention, in the mounting device for a vehicle carrier according to the present invention, the carrier is rotated and oscillated relative to the body frame by a swing coupling portion provided between the center of the carrier and the body frame. It is configured to be freely connected, and a receiving portion for absorbing displacement is provided between the body and the body frame of the radially extended portion with the swinging joint substantially at the center. The displacement on the vehicle body frame side is absorbed by the receiving portion, and does not exert the influence on the other side. Therefore, displacements such as "bending" and "twisting" of the vehicle body frame are also absorbed by the receiving portion, and the carrier does not cause structural fatigue failure unlike the related art.

It comprises a receiving portion 30 that indirectly connects 50d and a corresponding portion of the body frame. The swing joint 10 is provided between the horizontal joist 26a of the lower surface 50f of the aluminum van and the subframe 25, and the receiving portion 30 is provided between the two horizontal joists 26b of the lower surface 50f of the aluminum van and the subframe 25.

FIG. 2 is a front view of the swing joint portion 10. As shown in FIG. The swing joint 10 joins the joint fitting portion 11 provided via the horizontal joist 26a on the lower surface of the aluminum van 50 and the joint receiving portion 12 provided via the sub-frame 25 of the vehicle body frame 53. It is composed of a coupling pin 20 and a pin holder 20a (see FIG. 3). The structure of the coupling fitting portion 11 and the coupling receiving portion 12 will be described below with reference to an exploded perspective view shown in FIG.

The joint fitting portion 11 is formed by cutting a fitting pipe 11a having a cutout formed in the lower portion of the center of the lateral side of the horizontal joist 26a and penetrating the joint pipe 11a along with the center axis of the aluminum van by a reinforcing member 11c.

The coupling receiving portion 12 includes a bed 13 fixed to a sub-frame 25, split metals 16a and 16b, split metals 17a and 17b, and set bolts 18, 18, and 1.
8 and 18. The bed 13 is formed to have an upward U-shaped cross section, and opposing rising pieces 13a,
A U-shaped notch 14a is provided at the center of 13a,
14b, and a guide 15 is provided outside the notch 14a.
a, 15b, and guides 15a, 15b (not shown) are provided outside the notch 14b. Notch 1 above
4a, split metal 16a, 17 for guides 15a, 15b
a, and the split metals 16b and 17b are inserted into the notches 14b and the guides 15a and 15b.
8, 18, 18, 18 form the coupling receiving portion 12.

The fitting pipe 11a of the connecting pin 20 having the fitting pipe 11a freely penetrated between the split metals 16a, 17a and the split metals 16b, 17b.
And the pin holders 20a, 20a are set at the ends of the held coupling pins.
Has a structure for preventing the metal from falling off the split metals 16a, 17a and 16b, 17b.

The coupling fitting portion 11 is assembled to the coupling receiving portion 12 by inserting the coupling pin 20 into the fitting pipe 11a of the coupling fitting portion 11 and simultaneously inserting the coupling pin 20 into the bed 13 of the coupling receiving portion 12.
The split metals 16a and 16b are inserted and set. Next, the external projection of the coupling pin 20 inserted into the fitting pipe is placed on the set split metals 16a and 16b. Next, the outer projection of the mounted connecting pin 20 is sandwiched by the split metals 17a, 17b, and set around the connecting pin 20 by set bolts 18, 18, 18, 18 so as to be rotatable around the connecting pin 20, and the pin holder 20a,
20a is fixed to the end of the coupling pin 20, and the attachment is completed. In addition, as shown in FIG. 3 (B), when assembling, an appropriate gap t is provided between the split metal inner side surface 12a of the coupling receiving portion 12 and the end 11b of the fitting pipe of the coupling fitting portion 11. It is possible to swing back and forth in the YY direction (front and rear direction of the vehicle). Further, as described above, between the connecting pin 20 and the fitting pipe 11a and the split metal 16a,
Since the fitting state between 17a, 16b, and 17b is configured to be playable, rotation around the connecting pin 20 is enabled.

FIG. 4 shows a portion 50a extending radially about the swing joint portion 10 substantially below the aluminum van.
A schematic configuration of receiving portions 30, 30 provided at corresponding portions on a sub-frame 25 provided on a body frame 53 corresponding to 50b is shown. As shown in the figure, the receiving unit 30
An elastic member 33b made of synthetic resin or the like is provided between the aluminum van side support member 32 provided on the horizontal joist 26b on the aluminum van side and the vehicle body frame side support member 31 provided on the subframe 25.
And the elastic member 3
This is set by pressing the support member 31 to an appropriate pressure via the 3a and the fastening washer 34.

Due to the structure of the receiving portion 30, the aluminum van 50 is provided between the supporting member 31 provided on the sub-frame 25 and the set bolt 35 and the washer 34 set on the supporting member 31 via the elastic members 33a and 33b. As a result, displacement caused by "bending" or "twisting" caused during running of the vehicle body frame 53 is absorbed, and the influence on the carrier 50 is blocked.

[0017]

According to the above configuration, since the vehicle body frame and the aluminum van are fixed by one connecting pin, even if a displacement input such as "bending" or "twist" is input from the vehicle body frame, the vehicle is provided on the lower surface of the aluminum van. Absorbed by the receiving portion made of the elastic member, the occurrence of excessive displacement in the aluminum van can be prevented, and the fatigue failure of the constituent members due to the repetition of the excessive strain can be prevented.
