Product Description

 

The wheel radial load fatigue tester is used for durability testing of wheels. The tester simulates the road surface with the drum surface, and the motor drives the drum to rotate. Each test station has a set of hydraulic servo loading system, which presses the test rim and tire assembly fixed on the station shaft onto the drum surface, and tests at a preset test speed and test load. The loading force value of each station can be set separately.
The drum of the test machine host is a smooth surface without obstacles. The test machine drum is driven to rotate by a motor and belt drive. The test load is controlled by a hydraulic servo closed loop, and the control system controls the high-precision servo control loading electric cylinder to achieve closed-loop servo loading.
A strong electric control box is configured to complete the drive control of the motor. The microcomputer control unit is configured with a commercial control computer. The computer has a built-in signal amplification A/D conversion integrated card board to complete the sensor signal amplification and signal analog-to-digital conversion. The computer software is a WINDOWS platform software with functions such as dynamic display, storage, and output of test reports. Through the human-computer interaction interface: test machine operation program management, parameter setting, data acquisition-display-recording of the test process, data calibration and equipment fault diagnosis. The control system automatically controls the test speed and load of the tire, automatically records relevant test data, and generates a test report in Excel format.

The test machine is mainly composed of a host and a control cabinet.
1. Host
1.1 The host part consists of a frame, a drum drive assembly, a test station loading assembly and a protective net.
1.2 The drum drive assembly includes: a transmission system and a drum assembly. The transmission system is driven by a motor through a belt drive to drive the drum to rotate. The motor realizes speed regulation under the control of the speed regulating device. The drum assembly includes: a drum, a main shaft and a pulley. Each test station loading assembly includes a trolley loading mechanism, a tire station shaft assembly, a linear guide, a load sensor and other functional modules. The trolley loading movement adopts a high-quality linear guide, and the tire station shaft rotation support adopts an imported high-quality bearing combination to ensure the precise operation of the station moving parts.
1.3 Each station has a set of tire pressure loss protection devices. During the test, if the tire pressure is reduced due to tire leakage or other reasons, the tire will be quickly retracted.
Each station has a set of retraction detection devices. When the tire retreats, the slide triggers the travel switch and the station stops retreating.
1.4 The testing machine is designed with a whole machine protection net. When the tire test is in progress, if the sliding door is opened, the testing machine will immediately alarm and stop.
1.5 The loading assembly of the test station is mainly composed of a loading cylinder, a guide part and a tire mounting device.
1.6 The cylinder is installed on the bracket, the load sensor is installed on the front of the cylinder, and the displacement sensor is built inside the cylinder.
2  Control cabinet
2.1 The control cabinet includes a power drive cabinet and a computer cabinet.
2.2The power drive cabinet is equipped with a motor speed control device to achieve precise control of the power system distribution and speed of the testing machine.
2.3 The computer operation interface is divided into program management, equipment operation, data recording, data calibration and equipment diagnosis interfaces, among which the login data calibration interface requires engineer authority.
2.4 The system records, stores and displays the test speed, load, time, cumulative mileage, cumulative time, tire dynamic/static radius, ambient temperature, etc. in real time.
2.5 In addition to realizing various control functions required by the tire high-speed durability performance tester, the control system can also realize the input and editing functions of the test program through the computer, as well as the status display of the test process, the alarm status display, the test report and the printing of the test results.
2.6 Provide operating software developed by the supplier with independent intellectual property rights and specially used for the tire high-speed durability performance tester. The test program is used to control and manage the test parameters and data of various tire types to meet the demander's personalized tire test program requirements.
