Vehicle Tires Test Machine Tire High Speed Performance Durability Tester Tire Burst Protection Testing Equipment

Tire High Speed Performance and Durability Testing Machine — Model: LR-Q370

This testing machine features a single-station design with the loading station positioned alongside the test drum. It is suitable for high-speed performance and durability testing of commercial vehicle tires. The machine simulates the road surface using the drum’s exterior, which is driven by an electric motor. The test station utilizes an electro-hydraulic servo loading system to press the tire and rim assembly—mounted on the station’s spindle—against the drum surface. Testing is conducted at preset speeds and loads, with parameters such as loading force and rotational speed being adjustable.

The machine incorporates the following functional modules to meet specific customer testing requirements:

1. Tire loading module
2. Drum drive module
3. Tire blowout protection function
4. Tire temperature monitoring function
5. Tire dynamic and static radius measurement
6. Tire inflation pressure measurement

The main drum features a smooth, unobstructed surface. It has undergone 3D simulation and dynamic balancing to ensure sufficient structural strength and stability during high-speed durability testing. The drum is driven by a motor via a belt transmission system. Test loads are applied through a closed-loop electro-hydraulic servo system, where the control unit regulates a high-precision servo-hydraulic cylinder to achieve precise, closed-loop loading.

A high-voltage control cabinet is configured to manage motor drive operations. The microcomputer control unit utilizes an industrial-grade computer equipped with an integrated signal amplification and A/D conversion card to process sensor signals. The system runs on the Windows platform, offering features such as real-time dynamic display, data storage, and test report generation. A human-machine interface (HMI) facilitates test program management, parameter setting, data acquisition/display/recording, sensor calibration, and equipment fault diagnosis. The control system automatically regulates test speed and load while recording relevant test data.

The testing machine primarily consists of the main unit and the control cabinet.

1. The main unit consists of the frame, the drum drive assembly, the test station loading assembly, and a safety guard.
2. The main frame is constructed from welded high-quality steel plate with robust connections; critical fasteners are high-strength standard parts, and rim connection bolts are manufactured using specialized processes. The structure possesses sufficient strength and rigidity to prevent deformation during long-term use.
3. The drum drive assembly comprises the transmission system and the drum assembly. The transmission system uses a motor and gear reducer to rotate the drum, with motor speed regulated by a speed control device. The drum assembly undergoes rigorous dynamic balancing, and the drum utilizes high-quality imported roller bearings to ensure stability under tire testing conditions.
4. The loading assembly consists of a hydraulic loading mechanism, a tire station axle assembly, linear guide rails, a load sensor, and other functional modules. The loading carriage moves along high-quality linear guide rails, and the tire station axle utilizes a combination of high-quality imported bearings for rotational support, ensuring precise movement of the station’s components.
5. A tire blowout protection device is included; the operator adjusts the size and position of the safety forks based on the tire’s outer diameter and width.
6. A device for detecting tire dynamic and static load radii is provided to measure these parameters.
7. A tire rolling circumference (radius) measurement device is included, featuring proximity switches and encoder discs installed on both the tire axle and the drum axle. As the tire and drum rotate, the proximity switches scan the encoder discs and emit pulse signals; the control system records the pulse counts from both axles and calculates their respective rotational speeds. The system then determines the tire’s rolling radius based on the known drum diameter and the rotational speeds of the tire and drum.
8. An infrared temperature sensor is provided to measure the tire surface temperature.
9. The test station loading assembly primarily consists of the loading hydraulic cylinder, the guiding mechanism, and the tire mounting device. The loading cylinder features a configuration combining guide rings and specialized imported seals, ensuring low friction and reliable sealing. The cylinder is mounted on a support frame; a load cell is installed at the front of the cylinder, while a displacement sensor is integrated internally. A linear guide rail system is employed, with the wheel mounting bracket attached to the rail, effectively protecting the load cell and loading cylinder. A Japanese Yuken servo valve is used for closed-loop control of cylinder load and displacement.
10. Maximum cylinder test force: ±150 kN.
11. Effective cylinder stroke: ±400 mm (total stroke: 800 mm).
12. Single-rod piston design. Sealing method: guide rings + servo-grade seals (e.g., Glyd rings, support rings; all components imported from Parker, USA).
13. Integrated internal displacement sensor; externally mounted electro-hydraulic servo valve.
14. Electro-hydraulic servo valve configuration: high-frequency response servo valve (21 MPa, 10 L/min); actuator features an integrated servo valve mounting base.
15. Hydraulic buffers are designed at the amplitude limit positions to prevent damage caused by loss of control during operation.
16. The hydraulic cylinder is equipped with one dynamic load sensor (DC) with a range of ±300 kN and an overload capacity of 150%.
17. The hydraulic cylinder is equipped with one NOVOTECK displacement sensor (range: 800 mm), integrated within the actuator rod.
18. Sensors are calibrated prior to factory shipment.

1. Flow rate: 10 L/min; pressure: 21 MPa; test pressure is adjustable as required.
2. The pump station comprises an oil pump, motor, high/low-pressure switching valve assembly, accumulator, oil filter, cooling system, oil tank, piping system, and pump station base.
3. The filtration system employs three-stage filtration: oil pump suction inlet (100 µm); pump station outlet (3 µm filtration accuracy); and intermediate pressure-stabilizing module (3 µm filtration accuracy).
4. A German Rexroth variable displacement pump is selected; it features low noise, excellent durability, and a long service life. Low noise: the linear conjugate internal gear pump utilizes a special gear design—featuring linear gear profiles and linear conjugate ring gear profiles—which virtually eliminates trapped oil zones during operation, ensuring smooth, steady sound characteristics even at high speeds. Long service life: the pump’s longevity stems from superior wear resistance; an oil film protects internal mechanical surfaces and functional components, resulting in negligible wear, even when using standard hydraulic oil.
5. The oil distribution unit consists of a high/low-pressure soft-switching hydraulic module—comprising a main relief valve, accumulator, auxiliary relief valve, directional control valve, and precision oil filter—designed to regulate system output pressure; it supports low-pressure startup and high-pressure switching, effectively preventing pressure shocks during system startup and shutdown.
6. The pump-motor assembly is equipped with vibration-damping devices (vibration-damping pads) to minimize vibration and noise.
7. Fully enclosed standard servo-grade oil tank. Equipped with devices for temperature measurement, air filtration, and oil level indication; includes protection functions such as alarms or automatic shutdowns for conditions like over-temperature, low fluid level, and clogged oil filters.
8. A water cooler is installed on the system’s oil return line.

1. The control cabinet assembly comprises a power drive cabinet and a computer cabinet.
2. The power drive cabinet houses the motor speed control unit, enabling power distribution and precise speed control for the testing machine.
3. The computer operating interface includes modules for program management, equipment operation, data recording, data calibration, and equipment diagnostics; access to the data calibration interface requires engineer-level privileges.
4. The system records, stores, and displays real-time data including test speed, load, duration, cumulative distance, cumulative time, tire dynamic/static radius, and ambient temperature.
5. In addition to performing the control functions required for the high-speed tire durability testing machine, the control system enables the input and editing of test programs via the computer, as well as the display of test status and alarm conditions, and the printing of test reports and results.
