1. Product introduction

The device is based on the car ABS/ASR/ESP braking system, equipped with the ABS/ASR/ESP system working schematic diagram to truly display the working process of ABS/ASR/ESP system during emergency braking.

F--lure teaching functions such as structure composition and action demonstration of ABS/ASR/ESP braking system.

Suitable for the teaching needs of theoretical teaching and detection and m--ntenance tr--ning for car ABS/ASR/ESP braking system.

 

2. Functional characteristics

1. Based on the real car ABS/ASR/ESP braking system, it fully displays the composition of the ABS/ASR/ESP brake system.

2. From the three -phase asynchronous motor, drive the front and rear axles to rotate to simulate the car. When stepping on the brake pedal urgently, the ABS/ASR/ESP system began to work, and the brake discs kept a small amount of rotation. The brake pedal could feel constantly playing feet, and truly demonstrated the work process of the car ABS/ASR/ESP system.

3. The tr--ning countertop is p--nted with color UV tablet inkjet circuit diagrams and hydraulic pipe diagrams. Students can intuitively control the circuit diagram and ABS/ASR/ESP braking system, understand and analyze the working principle of the control system.

4. Detective terminals are installed on the tr--ning table panel. You can directly detect the electrical signals of each sensor and control the foot of the unit, such as resistor, voltage, current, frequency signal, etc.

5. The tr--ning desk is installed with a pressure gauge, which can display the hydraulic changes of the braking total pump and the four braking split pumps in real time.
