3 Introduction to EMT System
Electric-drive Mechanical Transmission (EMT). Utilizing the electrically driven active synchronization to replace the conventional synchronizer friction, The EMT eliminates the clutch between motor and transmission, and eliminates the mechanical synchronizer in the transmission. Electric-drive Mechanical Transmission has the following advantages over conventional automatic transmissions: high efficiency and low cost as AMT(Automated Manual Transmission), low cost, and interruption time of DCT power (0.2s-0.8s).
Besides, the system applies the integrated design in motor and transmission structure. Following the concept of powertrain, Electric-drive Mechanical Transmission integrates the system in accordance with the assembly arrangement, which reduces the connection and positioning error brought by the components of the dispersion design. In the mean time, Electric-drive Mechanical Transmission also significantly reduces the system's vertical dimension, and effectively optimizes the power of the assembly layout while relieving the system weight.
