Abstract
A chassis dynamometer includes a load roller and a free roller both of which are driven by a tested object, such as, an automotive vehicle. The load roller is drivingly connected to a dynamometer and mounted onto a first rotary shaft for co-rotation therewith. The free roller is mounted on a second shaft such that the free roller is rotatable relative to the second shaft. A flywheel is mounted on the second shaft co-rotatably therewith for forming a simulated inertial load. A power transmission unit, such as, a combination of timing pulleys and a timing belt is provided for transmitting a driving power from the first shaft to the second shaft such that the second shaft is rotated fster than the first shaft. Since the second shaft i.e. the flywheel is rotated faster than the first shaft, i.e. the load and free rollers, an inertial load created by rotation of the flywheel is increased so that a weight of the flywheel can be reduced.
