Steering Gear Functional Test Rig


Suspension Behaviour Diagram
The single axle 11 D.O.F. K&C Rig TITAN allows the accurate characterisation of passenger cars and light commercial vehicle’s suspensions as well as stand-alone one wheel or single axle suspensions.
Kinematic & Compliance Test on Suspension

The K&C can perform the following tests:
– Toe change
– Camber change
– Wheel-base change
– Track change
– Wheel vertical rate
– Steering axis properties

Wheel Base Test Axis

TITAN features:
– very high stiffness of reaction frame
– High precision 6 D.O.F. wheel and wheel pan measurement by means of infrared shirt’s button size emitters and cameras.
– 3 D.O.F. mapping of car body deformation around loaded wheel
– single set-up for front and rear suspension’s measurement thanks to PLC controlled sliding table
– steering wheel drive by means of retractable arm
– 6 D.O.F. load platform with hub for digital transmission of forces data to DSP based decoding unit (one digital serial cable for 12 conditioners).
– Speed adjustable movie for 6 D.O.F. movements recorded during the test.

6DOF Test System - Complete

The 6 D.O.F. single axle test rig is capable to reproduce on a vehicle’s suspension the following road excitations:
– Vertical jounce motion
– Fore/aft displacement and loads
– Lateral displacement and loads
– Steering angles and torque
– Camber angle and torques

6 DOF Wheel Force Transducer

6 D.O.F. wheel force transducer mounted between wheel and spindle allows accurate field load histories. ITRM_Pro software suite allows high accuracy multi-axial time histories reproduction in laboratory.

Test Axial

The digital control electronics EU3000 features advanced control mode like:
– gain profiling
– modal control
– rain flow control and monitoring
– real time iteration
– peak & phase control

Steering Gear Endurance Rig - Test Actuators
Steering Gear Endurance Rig – Test Actuators

Steering column assemblies are characterized by the large number of models and solutions. Test systems need to be flexible to cover different models, in-car positions and environmental conditions.

Accuracy and repeatability are a must considering that, by their nature; steering gears are extremely safety critical.

Functional rig Sphere is capable of measuring accurately most of functionality of different steering gears models.

Multi-axial durability test systems, 3 to 7 axis, allow reproductions of fatigue block profiles as well as the reproduction of field time histories. Environmental conditions can be simulated while the test article is subjected to endurance.

Tire Coupled Steering Gear Test Rig
This rig allows the characterisation of the full steering chain as mounted on the car. The main target is to study the friction behaviour of the steering and replace the units which are no longer serviceable. The wheel pan is supported by hydrostatic air bearings.
Rated torque: +/- 200 Nm
Nominal angle : +/- 55 degrees

Alternate Torque Rotating System Clutch Disc

The Alternate Torque Rotating system ATR is designed to characterise clutches and Flying Wheel Dampers. The system uses the state of the art rotating torsion actuator. The ATR in its basic version features +/- 1 kN, +/- 1 degree alternate angle at 60 Hz and 6,000 rpm.

A cost effective camera can record the movement of the springs at different speed up to 6,000 rpm.

Rotation Shaft Test RigSeries Rotating Drive Shaft Test RigSeries Rotating Drive Shaft Test Rig

The drive train is mainly comprising propeller shaft, U-joints, differentials, half-shafts and constant velocity joints.

Each of these parts can be tested in static conditions or while rotating. In static conditions alternate torque are applied to the specimen without its rotation. To reproduce test conditions closer to reality, the specimen is subjected to rotation while alternate torque fatigue is applied. In the rotating type of test rigs are usually tested more than one specimen at the time, by chaining them together.

4 Square Test System for Half Shafts4 Square Test System for Half Shafts

In addition to alternate torque and rotation the Four Square rig allows the input of jounce motion and steering effects on half-shafts. ITRMPro software allows the simulation of field recorded time histories.

Wheel rims are safety critical components. They need to be carefully tested according European and International testing procedures.

Exhaust Piping Test System (2)

Exhaust test systems enable high frequency vibration to be reproduced in either a dummy or live engine manifold to simulate engine vibration. A burner allows to test the exhaust pipe system at field operating temperature.
