PURPOSE: A chassis dynamo system is provided to carry out normal travelling test of four-wheel driving vehicle in a condition equal to a real vehicle for securing the precision and reliability of the test without any two-shaft dynamometers. CONSTITUTION: A chassis dynamo system includes a driving motor(3) for generating a driving force according to a control signal of a main controller(1), front rotation rollers(7) connected to a front end of a rotation shaft of the driving motor and positioned at a lower part of front wheels, rear rotation rollers(9) connected to the front rotation roller via a power transmission element and positioned at a lower part of rear wheels, a torque sensor(19) mounted at a side of the driving motor for sensing the power generated from the front wheels to transmit a signal thereof to the main controller.
