Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a storage device for a spare tire in a vehicle, and more specifically, to a device for storing a spare tire in the rear overhang of a low-floor bottle car.

[Prior Art] Since spare tires are heavy, they are constructed to be rolled up to the vehicle frame and held by a hoisting device, that is, a spare tire carrier.
However, conventional devices of this type have a structure in which the spare tire is held directly below the spare tire carrier, making it impossible to obtain effective ground height and departure angle for the spare tire to accommodate the space of the spare tire carrier. There were flaws.

In addition, in the conventional type, no special idea was taken to drive the spare tire carrier, so the efficiency of winding up and unwinding the spare tire, that is, the storage operation was poor.

For example, Utility Model Publication No. 27-4910 shows a system in which a spare tire is moved up and down by a winding device, but since the spare tire is stored directly under the winding drum of the winding device, the winding drum cannot be moved up and down. If the spare tire is installed above the frame to provide a sufficient height above the ground, the loading platform will become higher by the amount of the winding drum, for example. Therefore, it is not possible to provide sufficient ground clearance for storing the spare tire.

Further, Japanese Patent Publication No. 40-5130 also discloses a technique for suspending a spare tire using a winding device, but the spare tire carrier still protrudes above the frame.

[Purpose of the invention] Therefore, the purpose of the invention is to provide a spare tire storage device that can prevent the spare tire carrier from protruding onto the frame and provide sufficient ground clearance for the spare tire. be.

[Structure of the invention] According to the invention, in a spare tire storage device that stores a spare tire between a pair of vehicle frames that are spaced apart from one another in the front and rear directions from a carrier bracket that is provided between the frames. a spare tire carrier that protrudes from and winds up the spare tire via a chain; and a tire stopper that is provided at an upper part between the frames opposite to the spare tire carrier and that guides the chain and holds the spare tire. There is.

[Operation and effect of the invention] Therefore, since the spare tire carrier and the tire stopper are provided facing each other in the front and rear direction, the spare tire carrier is provided at a relatively low position with respect to the frame so as not to protrude from the frame. On the other hand, the tire stop can be provided at a relatively high position relative to the frame. Therefore, the spare tire suspended by a chain via the tire stopper can have sufficient height above the ground, and can also have a sufficient departure angle. Therefore, protrusions on the frame can be eliminated and the effective ground height of the spare tire can be increased.

In addition, storage efficiency is good, and the removal and installation of the spare tire is easy.

[Preferred Embodiment] When carrying out the present invention, it is preferable that the tire stopper be installed at an angle with respect to the frame. In this way, it is possible to prevent the spare tire from interfering with the spare tire carrier.

[Embodiment] Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. Now, in FIGS. 1 and 2, the spare tire storage device according to the present invention has a tire stopper 10 provided between a pair of frames 1 and 1' extending in the longitudinal direction of the vehicle and spaced apart from each other. , and a hoist or spare tire carrier 30, which is similarly attached to a carrier bracket 20 provided between the frames.

As shown in FIG. 1, the frames 1 and 1' extend from the front F to the rear R of the vehicle.
Tire stopper 1 at the top of this widening part
0 is fixed to the frame 1, 1' by means of attachment means such as bolts and nuts 11. Although the tire stopper 10 may be mounted horizontally to the frame, it is generally installed obliquely so as to form an angle .theta. with respect to the frame, as shown in FIG. Further, since the spare tire T is held in contact with this tire stopper, an opening 12 through which a chain 31 for hanging the spare tire is passed is provided approximately in the center of the tire stopper. Brackets 13, 13 are erected across this opening, and a pulley shaft 14 is attached to these brackets.
A pulley 15 for guiding the chain 31 is provided on the shaft 14.

The carrier bracket 20 is the tire stopper 1
Although it may be provided behind the spare tire T
Since the diameter is large, it is desirable that the stopper 10 be provided at a portion where the frames 1, 1' are widened as much as possible, and that the carrier bracket 20 be provided at a position with a small distance between the frames in order to save material. As shown in FIGS. 1 and 2, the carrier bracket 20 is provided in front of the tire stopper 10 at a distance D of, for example, about 1/3 of the tire rim diameter. At approximately the center thereof, that is, at a position corresponding to the pulley 15, support stands 21, 21 are attached by welding or the like, and a spare tire carrier 30, which will be described later, is fixed onto this support stand with bolts 22, 22, etc. Furthermore, this carrier bracket 2
0 also functions as a reinforcing material, generally a shaped steel is used as shown in FIG. 1, and is fixed to the frames 1, 1' with bolts and nuts 23, 23.

The spare tire carrier 30 is constructed as shown in FIG. That is, a case 33 is provided between the pair of brackets 32, 32, and a chain wheel 34 is provided within this case so as to be freely drivable. As is well known to those skilled in the art, the chain wheel 34 has an engagement element formed on its outer circumferential surface with which the ring of the chain 31 engages, and when the chain wheel is rotationally driven, the chain 31 winds up or It is unwound and is attached to the drive shaft 35. Although not shown in the drawings accurately, a deceleration mechanism may be provided at the portion indicated by 36 or 37. It is also possible to provide a ratchet mechanism or the like to securely hold the spare tire.

The spare tire carrier 30 includes a frame 1,
In order to be driven from the side of the frame 1', the drive shaft 35 extends to the outside of one frame 1' as shown in FIG.
0 is formed.

Since the spare tire storage device according to the present invention is configured as described above, when storing the spare tire T, the chain 31 let out from the carrier 30 is lowered downward from the opening 12 via the pulley 15, and the spare tire T is stored. Fix the end to the rim of the spare tire T, etc. The chain wheel 34 is then driven by the crank 39. The spare tire is then rolled up and comes into contact with the tire stopper 10, as shown in FIG. 2, and is held in this position. It is clear that when a spare tire is required and is to be lowered, this can also be accomplished by the reverse operation of the above-mentioned operation. As shown in FIG. 3, it is advantageous to provide a chain guide rod 41 between the brackets 32, 32, and drive the chain so that the chain 31 sandwiches this rod, as this prevents the chain from becoming entangled.

[Summary] As explained above, according to the present invention, the spare tire carrier and the tire stopper are provided facing each other in the longitudinal direction, so that the spare tire carrier does not protrude from the frame and the spare tire has sufficient ground height. It can be made higher. Furthermore, the workability of storing and removing the spare tire can be improved.
