ASR then shifts from differential brake controlto engine control to reduce engine power. The ASR activates the differential brake valveto control the brake cylinder, and the engines driving torque is applied to the braked wheel. The ECU activates the ASR when the wheels rotation exceeds the slip threshold.
Demonstration:
Function ofdifferential spider gears
Function ofaxle drive (pinion, crown wheel)
Locking byhydraulic piston and multiple-disks.
The board is designed to analyze important circuits for analogue signal processing which are widely used in process controls. The board is supplied complete with a set of stackable, plug in cables of suitable lengths and colours and with a training manual. In particular, it is possible to analyze circuits for signal acquisition as sample holds or peak detectors and circuits for signal processing like differentiators and integrators.
