Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a pivot portion of a spare tire hanger support device that rotatably supports the base of the spare tire hanger.

To store the spare tire on the underside of the car body, rotate the base of the spare tire hanger 1 as shown in Figure 1 to prevent the spare tire from coming into contact with the fuel tank etc. fixed on the underside of the car body. A tire stopper 3 is provided on a bracket (not shown) that locks the free end of the freely pivoted bracket 2 and the spare tire hanger 1, and the spare tire is compressed between the tire stopper 3 and the spare tire hanger 1. I was trying to fix it.

For this reason, since a pressing force due to the compression of the spare tire acts on the tire stopper 3, conventionally the tire stopper 3
Among them, spare tire hanger 1, which is subject to particularly strong compressive force.
A reinforcing member 4 made of a comparatively heavy steel plate is fixed to the side of the tire stopper 3 that pivotally supports the base of the tire stopper 3 to give strength to the tire stopper 3 and prevent it from bending.

The object of the present invention is to provide a support device for a spare tire hanger that can obtain the strength of a tire stopper without using the above-mentioned conventional reinforcing members.

The present invention will be described below with reference to illustrative embodiments.

11 is a spare tire hanger attached to the lower surface of the vehicle body 12, and the base end of the spare tire hanger-11 is fixed to the recess 13a formed on the lower surface of the bracket 13 fixed to the lower surface of the vehicle body 12, and to the lower surface of the bracket 13. The spare tire hanger 11 is rotatably held between the supports 1-14, and the tip of the spare tire hanger 11 is a free end, and the free end has a locking device provided on the lower surface of the rear end of the vehicle body 12. ]5
A hook 18 is attached that engages with a support pin 17 that is fitted into the support 16 of.

19 is a rock bolt. 20 is the above bracket 13
The tip of the support 14 is fixed near the bottom base of the tire stopper 20.

Reference numeral 21 denotes a tire stopper fixed to the lower end of the locking device 15 and a bracket 22 provided adjacent to the locking device 15, and a spare tire 23 is mounted in reverse at the tip of the tire stopper 21. A stopper 21a for preventing this is extended.

Therefore, when the spare tire 23 is placed on the spare tire hanger 11 in the opposite direction, the wheel task 24 of the spare tire 23 is placed on the stopper 2 as shown in FIG.
1a and cannot lock the hook 18 to the support pin 17, it is possible to prevent the spare tire 23 from being mounted in the opposite direction.

25 is a fuel tank.

The load relationship of the base portion of the spare tire hanger 11 having the above configuration when the spare tire 23 is attached is as follows.

(See Figure 3) Since the spare tire 23 is compressed and fixed between the spare tire hanger 11 and the tire stopper 20, an upward pressing force P acts on the tire stopper 20, and at the same time, the support part of the spare tire hanger 11 A reaction force Q1 of compressive force acts on the support 14, and the support 1
A load Q2 also acts on the fixed portion A of the tire stopper 20 and the tire stopper 20.

Therefore, when the tire stopper 20 is a cantilever support beam as described above, the tire stopper 20 has the above-mentioned pressing force P.
In addition to this, a downward load Q2 also acts on the A section, so the bending moment is reduced as shown in FIG. 5, and upward deflection can be reduced.

As described above, according to the present invention, the lower surface of the bracket that pivotally supports the base of the spare tire hanger and the lower surface of the tire stopper are connected by a support, and the bending moment 1- applied to the tire stopper is reduced. It is possible to obtain the same strength of the tire stopper as the conventional tire stopper without using a relatively heavy reinforcing plate such as that of the conventional tire stopper, which makes it possible to reduce weight and cost.

[Brief explanation of the drawing]

Fig. 1 is a partial perspective view showing how the base of a conventional spare tire hanger is attached, Fig. 2 is a side view of the lower part of the vehicle body showing how a spare tire is attached using the spare tire hanger according to the present invention, and Fig. 3 is the same as above. FIG. 4 is an exploded perspective view of the same as the above, FIG. 5 is a graph showing the bending moment of the tire stopper according to the present invention, and FIG. 6 is a locking device section showing the case where the spare tire is mounted upside down. It is an enlarged side sectional view showing the state. 11 is a spare tire hanger, 13 is a bracket, 14
20 is a support, 21 a is a tire stopper, and 21 a is a prevention stopper.
