<ISTLER measure, analyze, innovate. RoaDyn P1ST, P1MT, P1HTWheel torque transducers for utility vehicle applications The RoaDyn P1ST, P1MT and P1HT wheel torque transducers are universal sensors for measuring the traction torque My of utility vehicles. • Two independent measuring ranges of 10 % and 100 % at full resolution • Easy and quick assembly on various vehicle types with appropriate adaptions • Short setup times • Low additional unsprung mass and low moment of inertia • Automatic identification of the wheel torque transducer (telemetry) • Available as single, super-single and twin wheel Description The measuring system has three main components: the wheel torque transducer, the data transmission module and the on-board electronics (control unit). A wireless digital telemetry system is available for data transmission from the rotating wheel to the on-board electronics. The RoaDyn P1...T wheel torque transducer replaces the middle part of the rim, thus enabling optimum integration into the suspension system, i.e. in the most effective position for acquiring wheel forces or torques. Mounting the wheel torque transducer on the vehicle is comparable with changing a standard wheel. The traction torque My is measured with piezoelectric quartz sensors. The two switchable measuring ranges make it possible to measure small as well as very large torques extremely accurately. The signals are amplified and processed in the electronics system integrated into with the wheel. A digital system with CAN bus (telemetry) is available for transmission to the customer's data acquisition system. The transmission modules can be quickly and easily exchanged with one another. In addition to the traction torque My, the digital telemetry system (Type 9811B) is able to transmit three temperature signals (and a temperature signal of the wheel electronics). Application The RoaDyn P1...T transducers (Type 9299A...) have been designed and developed in close collaboration with the motor vehicle industry, specifically with practical and research applications in mind. The main focus is on: • Driving resistance measurements for reduction of C02 emissions • Research and development of ABS systems • Research and development of dynamics control systems • Vehicle performance measurements • Determination of powertrain efficiency • Recording load data for transmission development (simulation, validation) • Analysis of fading effects on brakes Kistler Group products are protected by several intellectual property rights patents.
