RS-130K Unique Features

The RS-130K 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-130K 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 130,000 N load cell. Road speed is measured by means of a magnetic pick up and a toothed wheel that is attached to the RS-130K 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 the vehicle being tested. Power for the retarders is supplied by the 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-135K. The transfer case has two gear sections and a neutral clutch. Ratios are 1:1 and 2:23:1.
