8AT input shaft welding assembly
The biggest difference between the continuously variable transmission and the ordinary automatic transmission is that it eliminates the complicated and cumbersome gear combination transmission, and only uses two sets of pulleys for the transmission. By changing the contact radius of the drive wheel and the driven wheel drive belt to change the speed, its design concept is very clever. Because the CVT can realize the continuous change of the transmission ratio, so as to obtain the best match between the power train and the engine operating conditions, improve the fuel economy and power of the vehicle, improve the driver's convenience of operation and the riding comfort of the occupants, so it It is an ideal automobile transmission.

CVT sedans also have their own gears, such as parking gear P, reverse gear R, neutral gear N, forward gear D, etc., but when the car moves forward automatically, it is very stable and there is no sudden jump. Continuously variable transmission (CVT--continuously variable transmission), it does not have the gear transmission structure of the traditional gearbox, but uses two transmission wheels that can change the diameter, and the transmission belt is sleeved in the middle. The basic principle is to wind the two ends of the transmission belt on a tapered pulley, and the outer diameter of the pulley is steplessly changed according to the oil pressure. When starting off, the diameter of the driving pulley becomes the largest diameter, while the diameter of the passive pulley becomes the smallest, achieving a higher transmission ratio.
It does not have the gear transmission structure of the traditional gearbox inside, but is driven by two transmission wheels that can change the diameter, and the transmission belt is sleeved in the middle. The basic principle is to wind the two ends of the transmission belt on a tapered pulley, and the outer diameter of the pulley is steplessly changed according to the oil pressure. When starting, the diameter of the driving pulley becomes the smallest diameter, while the diameter of the passive pulley becomes the largest, achieving a higher transmission ratio. With the increase of vehicle speed and the change of each sensor signal, the computer control system determines the control oil pressure to control the two pulleys, and finally changes the continuous change of the diameter of the pulleys, so as to achieve stepless speed change in the whole speed change process.
