Summary of the invention This invention relates to a chassis dynamometer in which the support shafts of the rollers on which the front and rear wheels of a vehicle are mounted are connected by a connecting shaft via a bevel gear mechanism to drive both the front and rear wheels to rotate. The connecting shaft is formed by spline-coupling a pipe-shaped output shaft and a spline shaft slidably provided inside the output shaft, and the support shaft of the roller is connected to the output shaft via a bevel gear. At the same time, the end of the output shaft is rotatably supported by a bearing in the bevel gear mechanism main body, and the spline shaft is formed hollow, and a guide ring is attached to the shaft end, and this shaft end is placed inside the output shaft. They are constructed so that they fit together slidably to minimize vibrations that occur during operation, and at the same time, by forming the spline shaft hollow, the natural frequency of the spline shaft is increased to prevent resonance even during high-speed rotation. The purpose of this is to reduce vibration during operation and the accompanying noise, and to extend the life of the gear.

ることが必要とされる。C. Problems to be solved by conventional technologies and ideas A chassis dynamometer, which aims to conduct vehicle running tests more accurately, is a system in which rollers on which the front and rear wheels of a vehicle are mounted are connected by a connecting shaft and rotated together. There is a wheel drive type chassis dynamometer.
However, in this case as well, the chassis dynamometer is required to have a variable spacing between the rollers so that it can be used for any size vehicle under test.

た。 Therefore, the connecting shaft must be perpendicular to the roller support shaft and must be movable in the axial direction, and conventional bevel gear mechanisms that have such a mechanism have been designed to avoid vibrations and vibrations during operation. Noise caused by vibrations is transmitted to the vehicle through the rollers or input into the measuring equipment, interfering with accurate measurements, and furthermore, the connecting shaft may cause resonance in the high rotation range.
There was a problem in that it was not possible to collect driving data of vehicles at high speeds, which is particularly required these days.
