According to the double-overrunning clutch mechanical type shaft end output self-adaptive automatic transmission electric drive system, reasonable matching of two overrunning clutches is used, the transmission ratios are arranged reasonably, so that the whole structure is simple and compact, reverse gear transmission, low-speed gear and rapid-gear transmission share a transmission route, interference does not occur, the integral performance is guaranteed, the shaft sleeve is output by the power and the third shaft, the double-overrunning clutch mechanical type shaft end output self-adaptive automatic transmission electric drive system is applied to electric vehiclefield, and applied to other variable torque mechanical transmission fields; and meanwhile, it is guaranteed that a larger output torque is further ensured through shaft sleeve output.

Description

technical field [0001] The invention relates to a transmission, in particular to a double overrunning clutch mechanical shaft end output self-adaptive automatic variable speed electric drive system. Background technique [0002] The working conditions of mechanical transmission systems are generally complex, and torque needs to be distributed to realize the transmission of different loads and speeds. Taking electric vehicles as an example, the driving environment is complex and changeable. Moreover, the electric drive method commonly used in existing electric vehicles is a motor-driven fixed-speed ratio, and the reasonable range of high efficiency is narrow and limited, resulting in a vicious circle, resulting in the following problems: [0003] 1. It can only work within the torque range of a certain working condition. [0004] 2. In order to meet the road conditions under the condition of constant speed ratio, the speed of the motor can only be increased, which increases ...
