Title:
TESTING APPARATUS OF VEHICLE DRIVING SYSTEM
Document Type and Number:
Japanese Patent JP3045328
Kind Code:
B
Abstract:
PURPOSE: To maintain the inertia of a driving shaft to be low while simulating faithfully the vibration of the shaft of a multi-cylinder engine and the vibration of the shaft from the low-speed rotation to the high-speed rotation without affecting the inertia in a vehicle driving system testing apparatus having a driving means of the low inertia simulating the engine.
CONSTITUTION: In the shaft driving system testing apparatus, an automatic gearshift 3 is coupled between a direct current motor 1 and a dynamo 22. The efficiency of the vehicle driving system is tested by controlling the direct current motor 1 through simulation of the engine. A low inertia driving means the rotating inertia of which is restricted to be as low as the engine is used as the direct current motor 1. A vibrator 4 to add the rotating vibration is set at the mounting part of the automatic geatshift 3 or the automatic gearshift 3. A swaying device 6 is arranged between an output shaft 23 of the direct current motor 1 and a mounting plate 5 of a test sample so as to shut the transmission of the vibration input of the vibrator 4 to the driving shaft.
