Comprehensive Hub Dynamometer Test Bench with Soundproof Room

Vehicle off-line testing equipment | Beijing Taiyuanxiang Technology Co., Ltd. comprehensive hub test bench (including sound insulation room) each wheel double drum, 4 sets of independent drive, speed 0-160km/h, braking force ≥ 4500N/wheel, reaction arm type force measurement; equipped with 10000 × 6000 × 4000 sound insulation room, wall sound insulation about 40dB (A) integrated hub test bench overall arrangement Each wheel double drum 4 sets of hub group can be independently controlled, the inertia of the drum group is designed according to the quality of the vehicle model, and the motor can simulate load changes, close to the real road load.The surface friction coefficient of the metal flame spraying process on the surface of the roller is not less than 0.75, which meets the requirements of GB7258-2017 for test inspection of braking performance. 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;照明 AC220V 50Hz；控制电源 24V DC供气 / 语言4.0-6.0 kg/cm²；手册中文/英文，铭牌与标牌英文，屏幕显示中文/英文隔音室室体10000×6000×4000mm（内侧），框架式全钢结构；隔音墙厚 80-83mm，矿物棉吸收率 ≥80%隔音性能墙壁隔音约 40dB(A)；窗约 30dB(A)；门约 25dB(A)；距室体 1m 处噪音低于 75dB隔音室照明 / 观察窗内部照度 500-700lux（防爆灯）；双侧观察窗为双层夹胶防爆玻璃，隔声 30dBA车辆出入门卷帘门式，门口尺寸 2600(宽)×2800(高)mm，与转鼓台控制系统通讯自动开关，停电可手动开启；另设 750×2000mm 安全/检修门隔音室通风上送风、下排风；进风量 ≥17000m³/h，排风量 ≥18000m³/h；通风机机箱 1m 处噪音低于 75dB平台承载自重 + 设备重量 + 85kg/m²检测项目车速表指示误差检验、制动力测试、车辆行驶性能（热车/换档/倒档）、巡航试验、加速性能测试、上下坡行驶试验、ABS/EBD/EBA/EDS/ASR/ESP/EPB 测试与诊断、发动机管理系统测试与诊断、自动变速箱测试与诊断、转动系统摩擦损失测定、新能源汽车动态放电与制动能量回收及续航里程测试联系我们北京泰元祥科技有限公司电话：010-89780650 手机：18611929790（李永坡）邮箱：liyongpo@taiyuanxiang.cn地址：北京市昌平区北七家镇宏福 10 号院 1 号楼 3027 室服务内容：方案设计与基础提资、设备制造与集成、运输安装调试、操作培训、验收支持、售后维修与备件供应注：本页参数与图片整理自产品技术方案，仅用于产品介绍；设备尺寸、配置及技术参数可按用户要求定制，如有更新恕不另行通知，具体以合同及技术协议约定为准。
