Test bench for performance of hybrid power vehicle transmission system

A hybrid driven vehicle transmission system performance test platform includes engine, speed torque sensor, ISG motor, transmission link support box, cross universal joint, electricity dynamometer, fuel consumption meter, control system, and others. The speed torque sensor is installed between the engine and the ISG motor, and the ISG stator connects to the clutch, and the transmission link support box and ISG motor stator are installed together to the engine installation surface; in the transmission link support box installs the transmission shaft, and the spline of the transmission shaft connects with the spline in the clutch friction chip, and the flange end of the transmission shaft connecting with the cross universal joint, the cross universal joint connecting with the power dynamometer. The invention integrates engine, motor and control system, increasing the speed and torque sensor and the transmission link support box, reducing the torque fluctuation in the transfer process, and it can respectively control the engine, motor speed and torque, and measure the parameters of system fuel consumption, battery voltage, current, charge state, and others.
