ADAPTIVE AUTOMATIC TRANSMISSION MAIN SHAFT ASSEMBLY EMPLOYING DOUBLE OVERRUNNING CLUTCH-BASED MECHANICAL SHAFT END-OUTPUT, TRANSMISSION, AND DRIVE SYSTEM

摘要

An adaptive automatic transmission main shaft assembly employing a double overrunning clutch-based mechanical shaft end-output, a transmission, and a drive system. The assembly comprises a transmission system, a shaft sleeve, and a third shaft. The transmission system comprises a low gear transmission mechanism, a reverse gear transmission mechanism, and an adaptive transmission assembly. The reverse gear mechanism has a transmission ratio I for transferring a reverse gear drive from a secondary shaft (12) to a main shaft (1). The low gear transmission mechanism has a transmission ratio II for transferring a low gear drive from the secondary shaft (12) to the main shaft (1). The transmission ratio I is greater than or equal to the transmission ratio II, and is used to output a power via a power outputting shaft. The invention utilizes the logical cooperation of two overrunning clutches, and configures appropriate transmission ratios, such that the overall structure is simple and compact, and reverse gear transmission shares a transmission path with low gear transmission and high-speed gear transmission without causing interference, thereby ensuring overall performance. The invention further utilizes a transmission shaft sleeve and provides an output via the third shaft, thereby being applicable to both electric vehicles and other variable-torque mechanical transmissions. In addition, a shaft sleeve-based output further ensures a large output torque.
