Description

[Detailed Description of the Invention] A. Field of Industrial Application The present invention relates to a chassis dynamometer that can test two-wheeled vehicles, three-wheeled vehicles, small four-wheeled vehicles, and ordinary four-wheeled vehicles with one unit.

B. Overview of the invention This invention has a small roller for two-wheeled vehicles and a large roller for tricycles and small four-wheeled vehicles mounted on a rotating shaft, and the drive wheels of a regular four-wheeled vehicle are attached to both rollers. By arranging the rollers at intervals such that the rollers ride on each other, and by making the rollers with the larger width removable from the rotating shaft using a clutch, it is possible to test two-wheeled vehicles, three-wheeled vehicles, small four-wheeled vehicles, and ordinary four-wheeled vehicles. This invention relates to a palm dynamometer that can perform the following functions.

C. Prior Art Conventionally, dedicated chassis dynamometers have been used to test not only motorcycles and four-wheeled vehicles, but also tricycles and small four-wheeled vehicles.

D. The problem that the idea aims to solve Therefore, equipment costs have increased, which has become a problem.

The present invention has been made in view of the current situation, and an object of the present invention is to provide a chassis dynamometer that can reduce equipment costs.

E Means for Solving the Problems In order to achieve the above object, the configuration of the present invention is such that a narrow roller for two-wheeled vehicles and a wide roller for tricycles and small four-wheeled vehicles are mounted on a rotating shaft. At the same time, the driving wheels of an ordinary four-wheeled vehicle are arranged at intervals such that they ride on both of the rollers, and at least the wider roller of the two rollers can be attached to and detached from the rotating shaft using a clutch. It is characterized by

F Effect By having the above configuration, two-wheeled vehicles, three-wheeled vehicles,
Tests for small four-wheeled vehicles and regular four-wheeled vehicles can now be performed using a single chassis dynamometer.

G. Embodiment Hereinafter, an embodiment of the present invention will be described with reference to FIG. 1, which is a front view with the upper half cut away, and FIG. 2, which is a plan view of the fixing means for the driven wheel (front wheel). The explanation will be based on FIG. 4, which is a side view of FIG. 3 and FIG. 2.

In FIG. 1, 1 is a narrow roller used when testing two-wheeled vehicles, and 2 is a wide roller used to carry two driving wheels when testing tricycles or small four-wheeled vehicles. The distance between the rollers 1 and 2 is such that the two driven wheels of a four-wheeled vehicle ride on the rollers 1 and 2, respectively.
In the figure, a flywheel (not shown) is connected to the A side, and a dynamometer (not shown) is connected to the B side.

Now, the roller 2 is loosely fitted onto the rotating shaft 4 via the boss portion 3, and the boss portion 3 is rotatable by bearings 5, 5. Rotation is transmitted and interrupted between the roller 2 and the rotating shaft 4 by a spline clutch 6. That is, when the roller 2 is in use, the spline clutch 6 is moved to the left as shown in the figure to transmit the rotation of the roller 2 to the rotating shaft 4.
When only the roller 1 is used and the roller 2 is not used, the spline clutch 6 is moved to the right to disconnect the boss portion 3 of the roller 2 from the rotating shaft 4. This is to remove the amount of inertia of roller 2 when performing a test using only roller 1 (for example, in the case of a two-wheeled vehicle).

Similarly, in this embodiment, a spline clutch 7 is also provided between the roller 1 and the rotating shaft 4, so that when only the roller 2 is used without using the roller 1 (for example, when driving a tricycle or small four-wheel vehicle). test), the spline clutch 7 is actuated to disconnect the roller 1 from the rotating shaft 4, thereby removing the inertia of the roller 1.

Of course, when both rollers 1 and 2 are used together (for example, when testing a regular four-wheeled vehicle), the spline clutches 6 and 7 are operated to engage the rollers 1 and 2 with the rotating shaft 4, and the rollers are 1 and 2 are transmitted to the rotating shaft 4.

Further, in this embodiment, as the driven wheel (front wheel) fixing means of the four-wheeled vehicle, those shown in FIGS. 2 to 4 are used. That is, belt 8
is tightened by a ratchet mechanism 9, and 10 is a ratchet spanner.

H. Effects of the invention As described above, according to the invention, rollers can be shared when testing two-wheeled vehicles, three-wheeled vehicles, small four-wheeled vehicles, ordinary four-wheeled vehicles, etc., and each vehicle can be tested on one vehicle. This can be done reliably and accurately using a chassis dynamometer, significantly reducing equipment costs.

[Brief explanation of the drawing]

Figures 1 to 4 show an embodiment of the present invention, in which Figure 1 is a front view with the upper half of the main part cut away, Figure 2 is a plan view of the front wheel fixing means, and Figure 3 is a top view of the front wheel fixing means. FIG. 2 is a front view, and FIG. 4 is a side view of FIG. Further, in the figures, 1 and 2 are rollers, 4 is a rotating shaft, and 6 and 7 are spline clutches.
