The RS-90K Towing Dynamometer

The RS-90K is designed to maintain constant drawbar pull or constant speed within the parameters set forth in the specifications and the performance curve charts.

The RS-90K is controlled from the test vehicle cab via the Hand Held Control Unit. Drawbar pull is accurately measured by means of a 5th wheel assembly that is held in place by a friction free linear bearing assembly and restrained by a 90,000 N load cell. Road speed is measured by means of a magnetic pick up and a tooted wheel that is attached to the RS-90K drive line.

Power is transmitted through a drive shaft to a two speed transfer case with a neutral clutch. Attached to the output shaft of the transfer case are four electric brake retarders. The retarders are controlled by signals from the in-cab instrumentation that is located in the vehicle being tested. Power on the retarders is supplied by a generator set and converted into a DC voltage through the power controllers located in the control cabinet.

The transfer case is controlled from the control panel located at the right front of the RS-90K. The transfer case has two gear selections and a neutral clutch. The transfer case ratios are 1:1 and 2.23:1.
