TW-2T-60K-S: heavy-duty wheel torque transducer, 81 kN·m
The TW-2T-60K-S is the 81 kN·m (60,000 lbf·ft) model of the heavy-duty wheel torque transducers; the TW-2T-50K is rated 67 kN·m. Its four-arm strain gage bridges measure all the drive and braking torque developed between the tire patch and the vehicle hub, for a single tire or a dual-wheel set; the maximum static vertical load is 6,100 kg (13,480 lb), against 4,500 kg for the TW-2T-50K. The stainless steel ring, Ø 469.9 mm (18.5 in), is waterproof, temperature compensated and adapts to 19.5 in and larger wheels. Non-linearity is 1 % of full scale or less and hysteresis below 0.5 %; it operates from −40 to 125 °C.
The ring has twenty-four Ø 17.5 mm (0.689 in) through holes on a Ø 435.6 mm (17.150 in) bolt circle, and a Ø 401.3 mm (15.800 in) center bore. Custom adapters duplicate the critical dimensions of the production wheel and place the tires on the production centerline.
It is suited to class 8 trucks, agricultural and construction equipment, and other large vehicles, on and off road, for drivetrain efficiency, brake system and anti-lock brake development, traction control and vehicle stability system design; the data serves component development, computer modeling and laboratory simulation and validation.
