Torque detector
TQ-3507
Even the slightest change can be accurately detected.
—Flange-type high-rigidity torque detector—
Improving energy efficiency is a challenge for next-generation vehicles.
To solve this problem, it is necessary to more accurately understand energy losses and to accurately capture even slight torque fluctuations in the power transmission mechanism.
Developed with a target torque capacity of 5 kNm, the TQ-3507 flange-type high-rigidity torque detector can accurately capture minute torque fluctuations.
1. Achieves excellent mechanical properties.
Achieves high torsional rigidity
TQ-3507: 13,000 kN · m/rad
The torsional resonance frequency of the detector alone is approximately 3,500 Hz.
We increased rigidity while maintaining accuracy. This increased rigidity allows for accurate simulation of actual vehicle driving conditions on the test bench, and also enables precise detection of even slight torque fluctuations.
Lightweight
By redesigning the structure, we achieved a weight reduction of approximately 3 kg compared to the previous model while maintaining high rigidity.
2. Achieves high-precision measurement.
The most fundamental characteristic for achieving high-precision measurement is the nonlinearity, including hysteresis, of the torque sensor. A high-precision option allows for accuracy of ±0.02% FS.
Standard Specifications Optional Specifications
±0.05% FS ⇒ ±0.02% FS
3. Highly durable, robust detector
It has passed load endurance tests of over 10 million cycles at a rated torque of ±100%. Furthermore, a sufficient safety factor is ensured for the material yield strength of the detector.
