Measuring steering wheel - V 2.1 - 05/2022

Product description Product description The product “measuring steering wheel” is used for installation inside of a vehicle. With an optional adapter kit it is mounted on top of the existing vehicle steering wheel. Without that adapter kit it can be mounted on the steering system after removing the original vehicle steering wheel. The “measuring steering wheel” measures the applied steering torque and optionally the rotation angle. The product must be handled as measurement sensor. Misuse and wrong handling can damage the sensor or lead to wrong measurement results. The measuring steering wheel...

Product description A ATESTEO Risk of fatal injuries! All safety instructions must be followed strictly. • The airbag of the original steering wheel must be deactivated and removed before installation of the measuring steering wheel. Usage of the measuring steering wheel with airbag is strictly prohibited and can lead to death. • When using the adapter kit, the measuring steering wheel must be mounted fix on the original steering wheel. • Without using the adapter kit, the measuring steering wheel must be mounted fix on the original steering system. A safe mounting solution must be chosen by...

Equipment installation Equipment installation Measurement body (torque sensor) The torque sensor contains the electronic for measuring the torque (strain gauges, amplifiers, and controller) and the angle. The sensor consist of a rotor and stator which are connected by bearings. Figure 1 Torque sensor (measuring steering wheel) without adapter kit Optional adapter kit components The adapter kit is optional. The components of this kit are used to install the measuring steering wheel on top of the original steering wheel. Figure 2 Cover for the torque sensor Figure 3 Connector disk (attached to...

Equipment installation Figure 8 Complete system incl. adapter kit Mechanical installation with adapter kit Remove the airbag of the original steering wheel. Please follow the instructions of the vehicle manufacturer. Risk of fatal injuries! Airbag can explode when handled wrong during uninstallation. Installed airbag can cause death when used in combination with the measuring steering wheel! Once the airbag is removed, the installation of the measuring steering wheel can start. 2.3.1 Holder mechanism Take the connector disk (attached to the torque sensor) and fix three splines at the pre-defined...

Equipment installation A ATESTEO Use two screws of type M6x16 to fix one spline. The clamping mechanism is used to fix the previously mentioned holder with the original steering wheel. First take the three parts shown in Figure 10. o © o Figure 10 Clamping components Table 1 Clamping components This set must be installed three times with 120° angle between each set. It’s a good way to do the assembly with two persons. One person is holding the parts, the other one is fixing the screws. Measuring steering wheel - V 2.1 - 05/2022

Equipment installation Take the “fixing block” and hold it behind the original steering wheel. Attach the “Round connector” to the “Fixing block” at the front side of the steering wheel. Place the “Flat connector” on top of the rear side of the “Round connector”. Make sure the track in both parts are combined. They will clamp the spline later. Figure 11 Track on the clamping material Use the “mounting screws” (see Figure 6) to fix the set together. They must be installed with the black handle on the backside of the steering wheel. Before tightening well, insert a spline into the track for each...

Equipment installation Steering wheel Figure 14 Steering wheel Place the steering wheel on top of the torque sensor (onto the cover, see Figure 2). Use screws of type M6x10 to fix the steering wheel (six screws). Risk of fatal injuries! If screws are not tightened well, steering control can be lost during driving! Risk of death. Check screws before every drive. Mechanical installation without adapter kit Remove the airbag of the original steering wheel. Please follow the instructions of the vehicle manufacturer. Risk of fatal injuries! Airbag can explode when handled wrong during uninstallation....

Equipment installation Risk of fatal injuries! If screws are not tightened well, steering control can be lost during driving! Risk of death. Check screws before every drive. Rotation angle measurement Whenever precise measurements of the rotation angle are required, the torque sensor must be connected with a fix part of the vehicle body (e.g. front window). Since the installation position of the sensor varies in each vehicle, the connection must be custom-tailored depending on the test vehicle. The torque sensor has a M6 winding where a connection system has to be applied. Typically a threaded...

Equipment installation Figure 16 Plugs at the torque sensor Risk of fatal injuries! Make sure the wires do not influence the driver during driving . Risk of death. Fix the wires at positions, where they do not influence the driver. Make sure the wires are not in tension since movement of the steering wheel will rotate the torque sensor few centimetres (if mounted without connection system to the vehicle body). Figure 17 VETAS evaluation unit Test signal The test signal is triggered by the terminal. Please connect the VETAS 3 by serial port to your computer and start the terminal program (included...
