This syatem enables measurement of 3 forces
(Fx,Fy,Fz)acting on 3 orthogonal axes to the running
axle at the wheel mounting part and 3 moments
(Mx,My,Mz)around the axes.The wheel itself is made
to act as the sensor to detect the 6-component force
and output signals are transmitted by the Slip-ring to
the measuring instrument.

Slip ring type
Sensor for Measuring Wheel Torques
during Driving
●To measure the wheel torque generated by driving or
braking an automobile.
●Applicable to braking and tracking control measurements
●Compact and ilghtweight
●Easy installation
●Optional angle detector can output signals of rotating
angle of wheel simultaneously in measurement
The wheel torque transducer is desinged to measure
torque initiated around the wheel of a running vehicle.
It consists of a strain gage type transducer, signal
transmitter (slip ring), dedicatde wheel and hub
adapter.The wheel and hub adapter can be replaced
to enable the transducer to be applied to various types
of Vehicles. The wheel torque transducer is suitable for
drive and brake tests as well as traction control tests.

Wheel Alignment Measurement System

-8
AUTOMOTIVE TEST EQUIPMENT
Uses a system that combines a wheel alignment measurement system and a 6 axle wheel force measurement system.
The wheel alignment measurement
system measures the relative
displacement of wheels when driving,
the camber, and the actual steering
angle. The signal obtained from
the encoder through a dedicated
processor is converted to a physical
quantity, and output as a voltage.
