IW4/IW7 WB/WBV

Description

1 Description

1.1Introduction

The IW4/IW7 WB/WBV (4WD) belong to the group of roller brake testers.

This class includes two different measuring methods to record brake forces:

!the testing of drive torque or

!the testing of drive power.

The former is applied in the MAHA IW4/IW7 WB/WBV (4WD) brake tester. The

IW4/IW7 WB/WBV (4WD) consists of a proven roller set and an open-ended electronic system based on a processor board with an integral operating system.

The standard test stand may be expanded to a complete test line by using the MAHA accessories.

1.2General Information about Brake Testing

To avoid skidding it is important that the brake forces of the individual wheels of one axle are the same. Just as important is the minimum brake torque for each individual wheel, so that when braking no vehicle brake is overburdened. Consequently, each wheel is tested individually on the brake tester.

For measuring the brake force, a static and a dynamic method are available. Using the static method the force necessary to rotate a wheel which is positioned on a plate, with applied brakes is determined. The dynamic method is more practice orientated - whereby the wheel is brought up to a predetermined RPM by the motor driven roller set and then the brakes are applied. A sensor roller measures the wheel revolutions. A comparison of the drive roller RPM to the sensor roller RPM determines how large the slippage is. For safety reasons, all MAHA brake testers automatically interrupt the brake test at a slippage of approximately 30%.

The measurement principle is the same for both methods of testing. The drive motor is supported in a rotary fashion (motor housing not supported); without any additional support, the drive shaft and the housing would counter rotate when under load, depending on the force distribution. The additional support consists of a flexible beam, on which the housing rests. The steel beam bends corresponding to the torque produced by the motor, which the beam resists. The torque is zero at the beginning of the static test. With the dynamic test method, the torque is just high enough to set the drive rollers with the vehicle wheel in motion with the brakes not applied.

A strain gauge is mounted on the transverse beam which converts the brake force into a usable electrical value.

For the IW4/IW7 WB/WBV (4WD)) brake tester the dynamic test method is used. This method ensures the most accurate measurement. There is simply no alternative for 4 wheel drive brake testing.
