The reaction arm type brake force measurement unit is used to accurately calculate the braking force of the wheel, which is far better than the calculation of the inverter current method.Product Overview The comprehensive hub test bench is used to test the driving performance and braking performance of the vehicle at the off-line and R&D stages. The testing host is composed of wheelbase adjustment device, hub group, exhaust system, control system, sound insulation and signal exhaust system. The equipment detection content and method meet the requirements of GB7258-2017 and GB38900-2020, and the detection beat is ≤ 300s/vehicle.Each wheel is equipped with a double roller, and the inertia of the roller set is designed according to the quality of the test model, and the motor has the function of simulating the load change, so as to truly simulate the vehicle road driving load change as much as possible. The equipment has extensive vehicle driving performance testing capabilities, and according to the needs of different users, it only needs to upgrade the software function to meet the requirements of various test specifications. The soundproof room of the equipment is used to block the noise generated during the hub rotation test from spreading to the workshop.Core advantages■ Each wheel double roller, 4 sets of hub group can be independently controlled, the inertia of the roller group is designed according to the quality of the vehicle model, and the motor can simulate the load change, close to the real road load. The surface of the■ drum adopts a metal flame spraying process, and the surface friction coefficient is not less than 0.75, which meets the requirements of GB7258-2017 for test inspection of braking performance.■ The reaction arm type braking force measurement unit is used to accurately calculate the braking force of the wheel, which is far better than the calculation of the inverter current method.The ■ sew brand drive motor (imported from Germany) is equipped with a Siemens inverter, which combines low-speed and high-torque with high-speed operation performance to achieve different test functions.■ Each motor is equipped with a speed encoder that reads the speed of the motor in real time to calibrate the speed of the vehicle. The■ lifting device is automatically controlled by PLC and powered by Festo brand airbags, which takes up less space and has a large lifting force;The lifting rod can be integrated with a wheel weight measuring device, and the wheel can be stopped at any position of the lifting rod to truly measure the wheel weight (the company's unique design). The■ wheelbase adjustment device is driven by a Siemens-branded servo motor with an adjustment accuracy of ± 1mm, which meets the needs of multi-model mixed-line production.■ Multiple safety protection: The side guide roller has both guidance and anti-slip, vehicle positioning sensor, belt safety shield (IP21 with sound absorption and noise reduction), rear and wheel side blocking roller, software safety protection, and the operator can still brake the vehicle smoothly in case of accidental shutdown.■ Supporting soundproof room: wall soundproof about 40dB (A), window about 30dB (A), door about 25dB (A), noise 1m away from the room is less than 75dB.The ■ soundproofing room is equipped with an independent ventilation system (upper air supply, lower air exhaust, air intake ≥ 17000m ³/h, air exhaust ≥ 18000m ³/h), with an inspection and maintenance platform and escalator with guardrails at the top.■ Long-lasting lubrication: The hub lubrication adopts the oil cup filling type, and only the lubricating oil needs to be filled into the oil cup during maintenance.Structure and details Inertial drum set: each wheel double drum, rotational inertia according to the quality design wheelbase adjustment device: servo motor drive, adjustment accuracy ± 1mm brake measurement unit and lifting device (Festo airbag drive) main technical parameters wheelbase range/wheelbase range 2500-3500mm; wheelbase 1400-2000mm; vehicle through the height 3800mm tire size/drive mode 13 "~ 22"; 2WD (FWD/RWD)/4WD; steering wheel LHD, RHD load-bearing capacity car travel area 1500kg/wheel;Pedestrian area 250kg/m ² speed measurement 0 ~ 160km/h, accuracy ± 0.5% full range static braking force ≥ 4500N/wheel, accuracy ± 1% full range pedal force/parking brake maneuvering force 0 ~ 800N/0 ~ 500N, accuracy ± 1% full range four-wheel speed deviation average speed ≤ ± 0.05% full range; speed change ≤ 0.5km/h roller parameters roller diameter 502mm (including coating), roller length 800mm, dynamic balance Q6.3 (DIN ISO 1940), spraying thickness 1mm, roughness Rz200, hardness RC55, surface adhesion coefficient ≥ 0.75, maximum test speed 160km/h Main external parts PLC Siemens S7-1500; touch screen Siemens 12 "; pneumatic system SMC; low-voltage device Schneider; control cabinet Rittal; industrial computer research and development; drum motor/wheelbase motor sew or Siemens servo motor; inverter Siemens servo inverter power main power supply AC 3 Phase 380V (± 10%) 50Hz; power supply capacity requirement 90KVA;Lighting AC220V 50Hz; control power supply 24V DC gas supply/language 4.0-6.0 kg/cm ²; manual Chinese/English, nameplate and sign English, screen display Chinese/English soundproof chamber 10000 × 6000 × 4000mm (inside), frame-type all-steel structure; soundproof wall thickness 80-83mm, mineral wool absorption rate ≥ 80%, wall sound insulation about 40dB (A); window about 30dB (A); door about 25dB (A); noise is less than 75dB soundproof chamber lighting/observation window internal illumination 500-700lux (explosion-proof lamp) 1m away from the chamber;The double-sided observation window is double-layer laminated explosion-proof glass, soundproof 30dBA vehicle entrance and exit roller shutter door type, door size 2600 (width) × 2800 (height) mm, automatic switch in communication with the drum table control system, power failure can be opened manually; 750 × 2000mm safety/maintenance door soundproof room ventilation upward and downward exhaust; air inlet volume ≥ 17000m ³/h, exhaust volume ≥ 18000m ³/h;The noise at the fan chassis 1m is less than 75dB platform bearing deadweight + equipment weight + 85kg/m ² test items Speedometer indication error test, braking force test, vehicle driving performance (hot car/shift/reverse), cruise test, acceleration performance test, uphill and downhill driving test, ABS/EBD/EBA/eds/ASR/ESP/EPB test and diagnosis, engine management system test and diagnosis, automatic transmission test and diagnosis, friction loss measurement of the rotating system, dynamic discharge of new energy vehicles and brake energy recoveryAnd endurance mileage test Contact us Beijing Taiyuanxiang Technology Co., Ltd.
