6HP20 planetary row
The 6HP20 planetary row is placed in the hydraulic system of the metal belt continuously variable transmission. The function of the slave cylinder is to control the tension of the metal belt to ensure the efficient and reliable transmission of the power from the engine. The active oil cylinder controls the position of the driving bevel wheel to move in the axial direction, and the metal belt of the driving wheel group moves along the V-shaped groove. Since the length of the metal belt does not change, the metal belt on the driven wheel group changes in the opposite direction along the V-shaped groove. The radius of gyration of the metal belt on the driving wheel set and the driven wheel set changes to realize the continuous change of the speed ratio. When the car starts, the working radius of the driving wheel is small, and the transmission can obtain a large transmission ratio, thereby ensuring that the drive axle can have enough torque to ensure that the car has a high acceleration. As the vehicle speed increases, the working radius of the driving wheel gradually decreases, the working radius of the driven wheel increases accordingly, and the transmission ratio of the CVT decreases, so that the car can travel at a higher speed.
