[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chassis dynamometer for testing the running performance of a vehicle such as an automobile, and more particularly to a belt used for attaching and detaching an endless metal belt in a chassis dynamometer in which a vehicle is supported by a belt rotating body. It relates to a transfer table.

[0002]

2. Description of the Related Art A conventional chassis dynamometer generally has a configuration in which a driving test is carried out by mounting a driving wheel of a vehicle on a cylindrical rotating drum. However, recently, a chassis dynamometer capable of reproducing conditions close to a road has been developed.

An example thereof will be described with reference to FIGS. 9 and 10. Reference numerals 11 and 12 denote a pair of rotating drums arranged side by side. An endless metal belt 13 made of, for example, stainless steel is hung on the rotating drums 11 and 12. This metal belt 1
A load supporting device 14 for fluid use (water bearing) is disposed below the lower part 3, thereby constituting a belt rotating body 15.

The belt rotator 15 configured as described above is arranged to support each of the four wheels 21 of the vehicle 2, and further includes a flywheel (not shown).
A load device such as a dynamometer is connected to the belt rotating body 15 to constitute a chassis dynamometer.

[0005] The chassis dynamometer described above has an advantage that tests for improving the safety and quality of the vehicle can be effectively performed because various tests of the vehicle can be performed in the building.

[0006]

The work to be performed when it is necessary to remove and attach the metal belt 13 due to inspection of the load supporting device 14 or the like. There is a danger to the operator, and there is a risk of damaging the metal belt 13, and the workability is very poor. Thus, the inventors have considered a belt transfer table 3 as shown in FIGS. That is, the belt transfer table 3 is a housing having one side wall opened so that the metal belt 13 can be inserted and removed. In addition, 30 in the figure is a base portion.

For example, the metal belt 13 is
To remove from the bed 12, first, as shown in FIG. 9, the opening of the belt transfer table 3 is placed on the bed 5 so as to face the rotating drums 11 and 12. Then, the operator pushes and moves the metal belt 13 to push it into the belt transfer table 3 and store it.

On the other hand, the metal belt 13 is
In the case of attaching to the bed 12, the metal belt 13 is stored in the belt transfer table 3, transported to the portions of the rotating drums 11 and 12 and placed on the bed 5, and an operation opposite to the above-mentioned removal is performed. Is to be worn.

Although the use of the belt transfer table 3 has improved the safety and workability as compared with before, the workability of mounting the metal belt 13 still has a problem.

[0010] a) The upper side of the metal belt 13 hangs down in the belt transfer table 3 and is lower than the rotating drums 11 and 12 and the load supporting device 14. For this reason, it is necessary to lift the metal belt 13 when mounting the work.

B) Since the height of the belt transfer table 3 is set to an average height of a plurality of (for example, four) belt rotating bodies 15, there is a slight difference between the respective belt rotating bodies 15. . However, since the height cannot be easily adjusted, the height and the inclination cannot be adjusted according to each belt rotator 15.
It is necessary to lift the metal belt 13 and work in the same manner as in the item a.

C) Since the belt transfer table 3 is simply placed on the bed 5, the positioning of the belt transfer table 3 is unstable, and it is not easy to install the belt transfer table correctly. It is bad.

D) In particular, because of the items a and b, it is necessary to prepare both a storage and storage case for the metal belt and a transfer table to be used when the metal belt is mounted. However, there is a problem that a special storage space is required.

The present invention has been made in view of the above circumstances, and a belt for a chassis dynamometer capable of holding an endless metal belt in a state similar to a state where a belt rotating body is mounted, and performing height adjustment and positioning together. The purpose is to obtain a transfer table.

[0015]

According to the present invention, an endless metal belt is hung between a pair of side-by-side rotating drums, and the metal belt is lowered by a fluid-using load supporting device provided between the pair of rotating drums. To form a belt rotating body,
A chassis dynamometer for performing a running performance test of a vehicle which supports the wheels of the vehicle with the belt rotating body. 1) A belt transfer for storing and holding an endless metal belt and for attaching the endless metal belt to the rotating drum. The transfer table is formed in a housing having one side wall opened, and a holding member is provided upright on the other side wall facing the opening, and the holding member and a lower inner wall of the housing are provided. The endless metal belt is configured to be held in an approximate state when the belt assembly is mounted.

The holding member may be either detachable (insertion fixing, screw fixing, etc.) or integral fixing.

2) Further, the holding member is formed of a rod member,
This rod member is formed into a round bar shape or a flat bar shape (arc-shaped, plate-shaped member).

3) Further, a height adjusting mechanism capable of freely adjusting the height of the belt transfer table from the floor is detachably provided at a lower position of the belt transfer table. This kind of height adjustment mechanism is not limited to the case where it is detachably provided, and may be integrally fixed to the belt transfer table.

4) Moreover, it is provided on a bed on which a positioning mechanism corresponding to the height adjusting mechanism is installed.

[0020]

According to the present invention: 1) Since the endless metal belt can be held in a state more similar to the state when the belt rotating body is mounted, the work of mounting the metal belt can be performed safely and easily.

2) Since the height on the bed can be freely adjusted and can be positioned and fixed on the bed, the safety and workability of the work can be further improved.

3) If the belt transfer table and the height adjusting mechanism are separated from each other, the belt transfer table can be used also as a belt storage box, and the height adjustment mechanism can be shared.
