Accurate measurement of durability quality and upgrading | LBSNJ-30 wheel radial load fatigue testing machine officially came out

Nowadays, the automobile industry is developing at a high speed. As the core component of driving safety, the durability test of wheels is the key link of quality inspection of parts and new product development. In order to meet the high-standard test requirements of the industry, Jinan force collar testing machine LBSNJ-30 wheel radial load fatigue testing machine is newly launched, which has become a professional equipment for wheel radial load fatigue testing based on mature mechanical structure, high-precision control system and perfect safety design.
The equipment simulates the real road conditions with the drum, drives the drum to run through the motor belt transmission, and cooperates with an independent hydraulic servo loading system to press the tire rim assembly on the surface of the drum, and completes the durability test according to the preset speed and load. The loading parameters can be independently set at a single station to adapt to various test schemes.
In terms of core performance and technical parameters, the equipment shows outstanding performance. The drum diameter is up to φ Φ1700mm, the radial runout is less than or equal to ≤0.10mm, and the surface roughness is less than or equal to 3.2 μ m, taking into account the running stability and test standards; The test tire has a wide range of adaptation, and can test tires with a minimum of 8 inches and a maximum tire mounting diameter of 1100 mm. The test speed covers 1km/h to 140km/h, and closed-loop speed control is adopted; The maximum load is 3T, and the load accuracy is controlled within 1%. The hydraulic servo loading mode ensures the load output to be stable continuously, which fully meets the strict requirements of wheel fatigue test.
The whole machine is divided into two modules: main engine and control cabinet, and the structural layout is scientific and reasonable. The main engine is integrated with frame, drum drive assembly, station loading assembly and fully enclosed protective net. The loading mechanism adopts high-quality linear guide rail, and the tire station shaft is equipped with imported bearings to ensure the long-term accurate operation of moving parts. At the same time, the equipment is equipped with three safety mechanisms: tire pressure loss protection, returning in place detection and door linkage shutdown: abnormal tire pressure will automatically return during the test, and the sliding table will stop immediately after it is in place; When the protective sliding door is opened, the equipment will immediately alarm and stop, so as to avoid the test risk in all directions.
Electrical and control system is a highlight of the equipment. The equipment is equipped with well-known brand components such as Advantech/EVOC, Schneider electric devices and Naxi servo valves, and the hardware quality is reliable. Supporting the independent research and development of special software for Windows platform, it integrates the functions of parameter setting, data acquisition, fault diagnosis, report output, etc., and can record many data such as test speed, load, accumulated mileage, environmental temperature and so on in real time, and automatically generate test reports in Excel format. The exclusive authority of engineers ensures the safety of data calibration and equipment debugging, and realizes intelligent control of the whole test process.
The supporting components of the equipment are selected from the mainstream brands in the industry, and the force sensor is made from the United States, the drum spindle bearing is made from NSK/FAG, and the linear guide rail is made from Shangyin brand, so as to enhance the durability of the equipment from the details. The overall size of the whole machine is about 14,900 mm× 1,500 mm× 2,500 mm, and the total weight is about 5 t. The operating conditions are suitable for conventional industrial scenes: it supports 380V industrial power supply, and the ambient temperature is 5℃-40℃, and it can work stably within 1,200 m above sea level.
In the field of automobile parts inspection, wheel fatigue testing machine is an important carrier to control product quality and optimize product design. With the four advantages of high precision, high stability, high safety and intelligence, LBSNJ-30 wheel radial load fatigue testing machine can be widely used in tire, rim manufacturing enterprises, third-party testing institutions, R&D laboratories of automobile enterprises and other scenes, helping the industry to improve the product testing level and build a safe defense line for automobile travel.
In the future, the equipment will continue to rely on technology accumulation, constantly optimize performance, and provide more professional and efficient test solutions for the auto parts inspection industry.
