The electric CVT is what mean?
Stepless speed change in a transmission device, the speed of movement within a certain range can be continuously changed transmission. In the machine, stepless speed change can be used to obtain the most suitable movement parameters, and it can change speed in the machine moving, save speed change time, increase productivity, and drive smoothly.
Hammer hammer is infinitely variable when you force when the frequency and speed of pneumatic hammer is increased, and vice versa. Don't use gear to control speed
CVT (Continuously Variable Transmission CVT) technology of CVT technology, it adopts the drive belt and a variable diameter main drivenwheel matched to transmit power, continuous change can realize the transmission ratio, so as to obtain the best matching of transmission and engine condition. The most common CVT are hydraulic mechanical CVT and metal belt continuously variable transmission (VDT-CVT)
