Transmission Test Bench

The transmission test bench is mainly a device used to test and develop the performance of various automotive transmissions. By simulating actual working conditions, various tests are conducted on the transmission to evaluate its working reliability and performance indicators, thereby enhancing the driving experience and reliability of the vehicle.

1. Performance testing

<s:1> Gear shifting quality test: Evaluate the smoothness, response speed and impact during the gear shifting process.

Transmission efficiency test: Measuring the energy loss of the transmission under different gears and loads is the key to improving fuel economy.

Drag loss test: Measures the friction loss of internal parts of the transmission in neutral or disengaged state.

2. Durability and reliability testing:

Fatigue life test: By applying a load higher than the normal level, an accelerated life test is conducted to verify the design life and structural strength of the transmission.

High-speed test: Verify the stability of the transmission at the limit speed.

High and low temperature testing: Testing the performance and reliability of the transmission under extreme temperature conditions.

3. NVH Test

Function: Identify and measure the noise, vibration and acoustic roughness generated by the gearbox during operation.

Objective: Locate the source of abnormal noise, optimize gear design, housing structure, etc., and enhance driving and riding comfort.

4. Function verification and calibration testing:

Youdaoplaceholder3 TCU (Transmission Control Unit) calibration: Quickly and safely complete the parameter optimization and functional verification of the TCU software on the test bench, significantly shortening the vehicle calibration cycle.

Fault diagnosis test: Simulate various fault modes (such as sensor failure, abnormal oil pressure) to verify whether the diagnostic and protection functions of the TCU are normal.

5. Production offline testing:

Youdaoplaceholder0 Function: After the transmission assembly is completed, conduct rapid automated testing to check for assembly errors, leaks, abnormal noises and other quality issues.

Objective: To ensure that every gearbox leaving the factory meets the basic quality requirements.

This type of dynamometer bench is composed of a motor system, control system, shock-absorbing pads, a large base plate, dynamometer and installation base, connecting parts, adjustable engine support, etc.

The testing process can be manually or automatically loaded. The test results can be generated into customized test reports, curve charts, etc. The process data can be generated into Word, Excel or PDF format files, and the data can be saved, edited, printed, etc. The interface of the test system is simple and clean, and it is convenient to upgrade and maintain. The company offers free training for operators and provides guidance on usage and maintenance.

Specific test items can be negotiated or customized by both parties. For technical support, please call 400-111-3688.
