Embodiment Construction

[0014]An AMT transmission lamination detection platform, including a computer, test tool, a control unit, a base 9, a drive motor 10 mounted on the base 9, and a transmission bracket 23 mounted on the base; the drive motor 10 output shaft connection is used for And the coupling 12 connected to the transmission output shaft is detected; the control unit 3 is connected to the test tool 2 through the wire harness, and the test tool 2 is connected to the computer 1 through the data line. The drive motor is independently controlled.

[0015]A counterweight 11 is also attached to the coupling 12 of the drive motor. A counterweight contributes to the connection between the drive motor and the transmission output shaft.

[0016]The computer 1 is a laptop; test tool 2 is a CANCase data tester; the control unit 3 microprocessor uses Freescale 32-bit microcontroller MPC5634; the drive motor is mounted on the motor holder 24 fixed to the base.

[0017]In order to clearly illustrate the technical charact...

Abstract

The invention relates to the technical field of transmission detection, in particular to an AMT transmission off-line detection platform and a control method thereof. An AMT transmission off-line detection platform includes a computer, a test tool, a control unit, a base, a drive motor installed on the base, and a transmission bracket installed on the base; the output shaft of the drive motor is connected with a shaft coupling; the control unit is connected to the test tool through the wire harness, and the test tool is connected to the computer through the data line. The control unit receives the off-line detection request from the operator, controls each pneumatic actuator to complete the off-line detection, the speed sensor and the position sensor feed back the real-time monitored speed signal and position signal to the control unit, and the control unit transmits the relevant status signals, etc. It is displayed and recorded by the computer in real time, which is convenient for the operator to check and judge whether the gear request is completed, whether the transmission shift is in place, and whether the countershaft brake achieves the braking effect.

Description

Technical field[0001]The present invention relates to the field of transmission detection, and in particular, an AMT transmission next line detection platform and a control method thereof.Background technique[0002]The AMT transmission is different from the conventional mechanical transmission. When the offline detection is detected, the operator cannot test it directly to the selection gear directly. The AMT's selection gear actuator is a pneumatic actuator, and it must be controlled by the control unit to complete the selected gear. The lower line detection platform of the current transmission applies only to the lower line detection of the conventional mechanical transmission, and there is currently a detection platform for the AMT transmission.Inventive content[0003]The present invention is directed to the prior art inadequate, and a method of detecting the next line detection platform and its control method can be simply efficiently efficiently efficiently efficiently efficientl...
