Capturing minute fluctuations accurately

Flange type High-stiffness Torque Detector

The improvement of energy efficiency has been required in future generation vehicles. The TQ-3507 Torque Detector developed for the measurement of torque capacity 5 kNm accurately captures minute torque fluctuations. It helps to grasp the energy loss precisely and improve energy efficiency of your system.

Features

1. Outstanding mechanical characteristics

Achieves high stiffness

Torsional stiffness : 13,000 kN · m/rad

The torsional resonance frequency (detector itself) is approx. 3,500Hz.
Increased stiffness while maintaining accuracy. The high stiffness enables to accurately reproduce the driving state of the actual vehicle, and capture even minute torque fluctuations.

Light weight

Reviewed the structure and achieved a weight reduction of about 3 kg compared to the existing model.

Application example in RC-S

2. High accuracy

The non-linearity including hysteresis is most basic characteristics required for highly accurate torque measurement. ±0.02 %F.S. is available with the optional high accuracy.

Standard 　　　　　Option
±0.05 %F.S.　⇒　　±0.02 %F.S.

Calibration with a high-precision torque reference device

3. High durability

It has passed the load durability test of 10 million times or more continuously with the rated torque of ± 100%. In addition, it is a highly durable detector that ensures sufficient safety for material proof stress.

Limit torque : 10 kN · m（200 % of rated torque）
Breakdown torque : 20 kN · m（400 % of rated torque）

Durability testing with continuous load testing system

Example of system configuration

Bench system for evaluation of EV drive unit

Accurately measures the transient torque when driving on a snowy road or on a wavy road that is reproduced on a bench.

Torque measurement system

Supports general-purpose digital communication to accurately transmit measured torque.
