HBT system for measuring torque and steering angle on motorcycles and ATVs

The HBT system is designed to simultaneously measure steering torque and steering angle on motorcycle handlebars and ATV steering shafts without altering their original operation. It integrates as a replacement or over-handlebar solution on the existing handlebar, with an adaptable mounting system tailored to the motorcycle’s specific features. Measurement relies on a stainless steel strain gauge sensor and a high-resolution inductive encoder for angle detection, all controlled by a dedicated control unit.

The measurement signal is transmitted in analog (±10 V) or via CAN 2.0 bus, with full thermal compensation over a range of −12 °C to 49 °C. Torque measurement covers a nominal capacity of 135 N·m, while the angle is acquired over ±180° with an accuracy of ±0.3°. The user interface enables simplified calibration via zeroing and shunt commands, with a maximum permissible speed of 333 rpm for angular measurement.

HBT applications include vehicle testing and development, particularly for analyzing steering forces in real-world conditions, optimizing assistance systems, or characterizing dynamic behaviors. It can also be deployed in academic research (two-wheeler mechanics, ergonomics) or in quality control to validate steering components after modification or wear.

The HBT includes the sensor, encoder, mounting brackets, and signal conditioning electronics, with a 9–36 Vdc compatible power supply. Custom mounting solution design is available as an option. The sensor’s total weight is 1.6 kg, with an allowable axial load of 440 N.
