1. Product Introduction
This equipment is based on the automotive ABS/ASR/ESP braking system and is equipped with a working principle diagram of the ABS/ASR/ESP system to truly demonstrate the working process of the ABS/ASR/ESP system during emergency braking.
It meets the teaching functions of the structure, composition and action demonstration of ABS/ASR/ESP braking systems.
It is suitable for the teaching needs of theoretical teaching and testing and m*ntenance tr*ning of automotive ABS/ASR/ESP braking systems.

2. Functional features
1. Based on the real car ABS/ASR/ESP braking system, it fully displays the structure of the ABS/ASR/ESP braking system.
2. The three-phase asynchronous motor drives the front and rear axles to rotate to simulate car driving. When the brake pedal is pressed in an emergency, the ABS/ASR/ESP system starts to work, the front and rear brake discs keep rotating slightly, and you can feel a constant bounce on the brake pedal, truly demonstrating the working process of the car's ABS/ASR/ESP system.
3. There are color UV flat panel printed circuit diagrams and hydraulic pipeline diagrams on the tr*ning platform . Students can visually compare the circuit diagrams with the actual ABS/ASR/ESP braking system to understand and analyze the working principle of the control system. 4. There are detection terminals installed on the panel of the tr*ning platform, which can directly detect the electrical signals of each sensor and control unit pins on the panel , such as resistance, voltage, current, frequency signals, etc. 5. The tr*ning platform is equipped with a pressure gauge, which can display the hydraulic changes of the brake master cylinder and four brake cylinders in real time. 6. A fault indicator light and a diagnostic socket are installed on the tr*ning bench panel, which can be connected to a special or general vehicle decoder to query the ECU code of the ABS electronic control system, read fault codes, clear fault codes, read data streams, and execute Self-diagnostic functions such as component testing, parameter setting, and waveform analysis. 7. Equipment panel cabinet: 1.5mm cold plate stamping and forming, with a m*ntenance door on the back; the base is welded with a steel structure, the surface is spray-coated, and has a self-locking caster device, which makes it flexible to move, safe, reliable, sturdy and durable. 8. The clutch is used to connect the brake disc and the motor output shaft, which can realize the braking differential of each wheel. When braking, the brake pedal keeps rebounding obviously. (Optional) 9. Mechanical assembly and fitter assembly virtual simulation software: This software is developed based on unity3d, with optional 6-level image quality. It is equipped with the design and virtual disassembly and assembly of reducers and shafting structures, and the design and simulation of common mechanical mechanisms . Mechanism resource library, typical mechanical mechanism (virtual disassembly and assembly of gasoline engine), the software is a whole software and cannot be individual resources. A. Reducer design and virtual disassembly interface can choose worm gear bevel gear reducer, two-stage expanded cylindrical gear reducer, bevel cylindrical gear reducer, coaxial cylindrical gear reducer, bevel gear reducer, and one-stage cylindrical gear reducer. Gear reducer. Worm bevel gear reducer: After entering the software, the assembly content is automatically played. Each step in the video has a text description . Secondary expandable cylindrical gear reducer: After entering the software, the content is played in the form of a video. The video content should include: Part name ( Scan the QR code to see the names of parts), disassembly and assembly demonstration (including disassembly and assembly), virtual disassembly (including overall, low-speed shaft, medium-speed shaft, high-speed shaft, box cover, box seat) conical cylindrical gear reducer, Coaxial cylindrical gear reducer, bevel gear reducer, first-level cylindrical gear reducer: click to enter and automatically jump to the edrawings interface. The models are all three-dimensional models. By clicking on the parts, the names of the parts are displayed, and the 360° view is av*lable Rotate, zoom in, zoom out, pan, and move parts to disassemble and assemble the entire reducer. At the same time, you can select the home button to return to the original state of the reducer. The bevel gear reducer and the first-stage cylindrical gear reducer have added the function of inserting a cross section, and the cross section can be freely dragged to observe the internal structure of the reducer. B. Shaft structure design and virtual disassembly and assembly interface optional parts recognition, disassembly and assembly demonstration, and actual operation. 1. Parts recognition: three-dimensional model and part name including helical gear, non-hole end cover, coupling, coupling key, shaft, gear key, hole end cover, shaft sleeve, deep groove ball bearing, any All parts can be rotated 360° 2. Disassembly and assembly demonstration: There are 2 built-in cases. When you move the mouse to the position of a cert*n part (except the base and bearing seat), the part will automatically enlarge and the name of the part will be displayed. It is equipped with disassembly and Assembly button, the function is to automatically complete the disassembly and assembly of the shaft system structure by the software. All three-dimensional scenes can be rotated, enlarged, reduced and translated 360° in all directions. 3. Practical operation: The three-dimensional parts are neatly placed on the table. The students manually select the corresponding parts and move them to the shaft system structure. The parts can be installed only when they are placed in the correct order and in the correct position. There is a restart button to facilitate students to restart. Conduct virtual experiments. When you move the mouse to a cert*n part position (except the base and bearing seat), the part will automatically enlarge and the part name will be displayed. C. Common mechanical mechanism design and simulation, optional hinge four-bar mechanism design and analysis, I\II type crank rocker mechanism design and analysis, offset crank slider mechanism design and analysis, crank swing guide rod mechanism design and analysis, hinge Four-bar mechanism with integrated trajectory, eccentric linear-acting roller push rod cam , and centering linear-acting flat-bottomed push rod cam. 1. Each mechanism should be able to input corresponding parameters, and the software can automatically calculate the parameters, and can perform motion simulation and automatically draw curves. D. The mechanism resource library includes 11 types of planar link mechanisms, 5 types of cam mechanisms, 6 types of gear mechanisms, 8 types of transmission mechanisms, 11 types of tightening mechanisms, 6 types of gear tr*n mechanisms, and 8 types of other mechanisms (mechanical equipment simulation) E , virtual disassembly and assembly of gasoline engines, optional crankcase assembly and disassembly demonstration, crankcase virtual assembly, valve tr*n assembly and disassembly demonstration, valve tr*n virtual assembly 1. Crankcase assembly and disassembly demonstration and valve tr*n assembly and disassembly demonstration both have disassembly button, assembly button, restart, and decomposition observation button. When the mouse is moved to a cert*n part position, the part will automatically enlarge and the part name will be displayed. The software automatically completes the disassembly and assembly of the shaft system structure. When the decomposition observation button is used, the three-dimensional model of the crankcase or gas distribution system automatically displays an exploded view, which can be rotated, enlarged, reduced, and translated 360°.
2. The three-dimensional parts of the crankcase virtual assembly and the gas distribution system virtual assembly are neatly placed on the desktop. Students manually select the corresponding parts and move them to the mechanism. The parts can be installed only when they are placed in the correct order and in the correct position. There is a restart button to facilitate students to re-run virtual experiments. When you move the mouse to cert*n part locations, the part names are automatically displayed.
