Automatic Transmission Assembly Performance Test Bench and Transmission Control Unit
Equipment Introduction
The automatic transmission assembly performance test rig consists of two parts: the bench part and the control cabinet part.
The bench part is equipped with a drive motor and an output eddy current loading device.
The control cabinet part includes a control computer, oil pressure gauges, and motor-eddy current control equipment.
WE OFFER THREE TYPES OF AUTOMATIC TRANSMISSION PERFORMANCE TEST BENCHES:
Type 1: Equipped with both torque and speed sensors, it can determine the completeness of gear engagement and test shift smoothness.
Type 2: Equipped with speed sensors, it can test gear engagement integrity and calculate the gear ratio.
Type 3: A simple test stand that provides a preliminary assessment of transmission operating performance. It features a compact size, is easy to integrate into workshop layouts, and offers high cost-effectiveness.
TEST BOARD
Different transmissions require different adapter plates. The dedicated adapter plates we provide are the key to connecting the transmission to the tester. You can quickly select the right plate based on the transmission model. From the very design stage, each adapter plate has been developed with versatility in mind, and can typically be perfectly matched to 5 to 6 types of transmissions. This truly enables one plate for multiple uses, effectively reducing fixture costs and improving testing efficiency.
For details, please refer to the operation manual.
OUTPUT SHAFT
We offer a variety of output shafts for different transmissions. You can flexibly select the appropriate output shaft according to the specific transmission model.
For more detailed information, please refer to the operation manual.
TRANSMISSION CONTROL UNIT
Developed independently by Huadu Worldwide Automatic Transmission, we offer three transmission controller models suitable for automatic transmissions (AT), continuously variable transmissions (CVT), and dual-clutch transmissions (DCT), respectively. Each controller is equipped with 13 output channels for controlling solenoid valves, including 8 PWM (Pulse Width Modulation) channels and 5 switching channels, supporting the testing of 9-speed, 10-speed, and even 12-speed transmissions.
In terms of signal acquisition, the controller can detect signals from 4 speed sensors, 8 pressure sensors, and 2 temperature sensors. Using the controller, you can perform shift operations on the transmission and monitor all pressure and speed states in real time during the shifting process.
During testing, the controller collects and stores data such as pressure and rotational speed. You can upload the pressure and speed data from each shift event (e.g., Reverse $$ Drive, Neutral $$ Drive, \lvert s t \to 2 \nVDash d , 2 \mathsf { n d } \to 3 \mathsf { r d } , etc.) to a personal computer for subsequent shift quality analysis.
Please note that for different transmission models, you will need to purchase the corresponding test wiring harness connectors separately. In addition, we provide remote update services for the test program via the internet.
CVT TRANSMISSION CONTROLLER
Now, the CVT controller is applicable for testing the following transmission models:
CVT Test Controller can switch between 2 modes freely: It can either perform a fully automatic test with one click, or carry out independent testing on individual test items, flexibly meeting the in-depth needs of both R&D and debugging.
