Dynamic testing bench used for automatic mechanical gearbox of hybrid power vehicle

The utility model relates to a dynamic testing bench used for an automatic mechanical gearbox of a hybrid power vehicle. The dynamic testing bench includes a platform. A T-shaped groove is arranged in the platform. The dynamic testing bench is characterized in that the dynamic testing bench also includes an engine, an electronic control clutch, a drive motor, a torque sensor and an inertia wheel; the engine is connected with the drive motor through the electronic control clutch; the automatic mechanical gearbox is connected with the torque sensor through a flange plate; the torque sensor is connected with the inertia wheel through the flange plate; and the engine, the electronic control clutch, the drive motor, the automatic mechanical gearbox, the torque sensor and the inertia wheel are installed on the platform through a fixing support. The dynamic testing bench has an advantage that dynamic performance of the automatic mechanical gearbox of the hybrid power vehicle can be tested accurately and conveniently.
