Integrated hub testing equipment —— MDT-2000 Place of origin: ChinaManufacturing company: IYASAKA Testing conceptsThis system measures and evaluates vehicle parameters including speed, acceleration, braking force, driving force, parking force, speed sensors, ABS, ESP, VSA, and tachometers. It simulates various dynamic driving scenarios in road-like environments. The system performs high-precision measurements of speed, driving force, and braking force during testing, while enabling data acquisition and computational analysis to ultimately determine compliance with standards.The equipment meets the relevant provisions in the latest version of GB7258-2017 "Technical Conditions for Safe Operation of Motor Vehicles". The drum test bench is equipped with functions such as high-speed drum detection, dual-axis braking force detection, and electric vehicle testing. The equipment meets the technical requirements of GB/T13563-2007 "Speedometer Inspection Bench for Drum-Type Vehicles" and JJG909-2009 "Calibration Regulations for Speedometer Inspection Batches for Drum-Type Vehicles".test itemTransmission function test (AT/MT)Thrust testSpeedometerSpeed test on the roadABS/ESP testProduct featuresMore test functionality and higher test qualityHigh measurement accuracy, small repeatability error and stable operationThe modular design is simple to arrange, easy to maintain, high cost performance, low maintenance cost and use costActual road resistance simulationThe motor drive system is controlled by a four-quadrant full digital AC driver.Based on servo drive control technology, it has better static and dynamic characteristicsHigh speed communication, convenient interface and help document operating interfaceFlexible open control platform, using IEC61131 standard programmingBuilt-in control software, comprehensive process control and various safety functions, more reliable useThe rectification mode is IGBT active rectification, the power factor is close to 1, and it is not affected by the power grid fluctuationWide power supply voltage range (380-480V±10%; 48-67Hz)scope of supplyMDT-2000 integrated hub turning equipment includes:Supply scope and servicedriving system4 x 55kW heavy duty motor4 x 55kW heavy load transducerrollers setdiameter ：502mmRoll length: 800mmMode: double drum/unit4 units/standsAxis adjustment systemAxle spacing adjustment speed: more than 60mm/s; Axle spacing adjustment accuracy: ±1mm.constrained systemTwo limit safety rollers on the rear axle to prevent the car from withdrawing backward from the test benchTwo limit safety rollers on the front axle to prevent the car from withdrawing forward from the test bench4 lateral limit pulleys: to avoid damage to the tire and rim caused by the lateral movement of the car (mechanical)lifting jackOne set for each front and rear axisLift capacity: 1000kg/ wheelWaste gas collectionTwo sets of flaps corresponding to the left and right exhaust pipesTwo sets of collection discs (one set at the front axle and one set at the rear axle): used to collect liquid exhaust condensate, coolant, etc. The engine compartment exhaust is sucked at the front axleframePit size: 8200 × 5000 × 2200mmEquipment cover plate and surrounding cover plateelectrical control cabinetThe Witu PS series has an air-conditioned cooling systemSiemens 1500 or other mainstream PLC systemPC system, including Advantech 610L industrial computer and UPS and 1 9TFT cabinet door displayVehicle identificationThrough the VIN code (barcode and keyboard)Select via remote controlDriver assistance22 TFT is equipped with a protective cover and installed on the left side of 1500~2000 in front of the driverThe driver operates the button box and wireless remote controlRed and green lightsCalibrate the tooling1 set of torque calibration device and software: used for the calibration of braking force measurement specified in GB7258-2017.One speed calibration device and software: used for the calibration of speed measurement specified in GB7258-2017.ABS/ESP testGM bus diagnostic, customer choicewheel loadCustomer selects, measure wheel weightSoundproof roomCustomer choice, factory noise standards, front and rear roller shutter doors, etcHand pull/step force gaugeSampling, customer choiceessential parameterMaximum allowable axle load2000 kgtread1200～2000㎜tyreΦ400㎜～φ9 00㎜Roller configurationTwo wheels in the front and two wheels in the rearInner diameter of drum × outer width (center spacing)800mm×2, 400㎜ （1, 600㎜）Roll diameter × length × shaft spacingΦ 502mm × 800mm × 620 (adjustable) ㎜Basic inertia of drum assembly1000 kg (optional)Shaft speed adjustment modeServo motor control, automaticAxis adjustment range1940 mm ~ 2840 mm (adjustable)Shaft speed adjustment and accuracyGreater than 60mm/s±1.0mmTest speed range0～1 70km/hSpeed test errorLess than 0.1km/hIntermediate liftersInstalled between each pair of rollersjacking capacityMore than 200kgVehicle drive and simulated moment of inertia section4 vector mo
