Technology meets future.

Manually operated steering test bench

A hand-operated steering test bench was developed to sporadically check steering systems in incoming goods. The test bench measures parameters such as steering smoothness, noise, torque and valve function and records the data on a multi-channel recorder. The system consists of a basic structure with a clamping device, a control cabinet with a built-in recorder and measuring electronics as well as a hydraulic unit for supplying oil to the steering system. Various tests such as the displacement force, noise development, torque test and valve characteristic curve can be carried out.


A test stand was required for the sporadic testing of steering systems in the incoming goods department.

The following parameters are measured with the test stand:

  • Smoothness of the steering
  • Noise development
  • Torque
  • Valve function


The data must be recorded on a multi-channel recorder.



The test stand consists of three parts:

  1. Basic structure with clamping device, handwheel with measuring shaft, load cylinder and measuring path system
  2. Control cabinet with built-in 2- or 4-channel recorder with power supply, measuring electronics and operator panel
  3. Hydraulic unit with heater for supplying the steering system with oil


Executable tests:

  • Smoothness of the steering (displacement force): The load cylinder is used to determine the displacement force and the movement from stop to stop and document it as a force/displacement diagram. Any irregularity in the movement can be recognized in the recording.
  • Noise development: The noise development can be tested by regulating the flow rate and increasing the pressure.
  • Torque test: The test is carried out without hydraulic assistance. The steering is moved slowly, from stop to stop. The forces and the path are documented as a torque-path or angle diagram.
  • Valve characteristic: The characteristic curve recording of the steering torque via pressure shows the pressure amplification of the power steering control valve. The measurement is taken shortly before the steering stops and the leakage current of the valve can also be measured.
