Embodiment Construction
[0016] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0017] figure 1 It is a structural schematic diagram of the first embodiment of an electric assisted shift transmission of the present invention. As shown in the figure, an electric assisted shift transmission includes a flywheel shock absorber J, an auxiliary motor T, planetary gear set X, planetary front input shaft SR, first input shaft SR1, second input shaft SR2 and output shaft SC, a mechanical transmission system C arranged between the input shaft and the output shaft and the output end SCD; The ring gear X1, the planetary carrier X2 and the sun gear X3 in the high-speed planetary gear set X control the relative fixation or rotation between the ring gear, the planetary carrier and the sun gear and control the torque between the planetary front input shaft SR and the first input shaft SR1 The first clutch K1 that is connected or disconne...

An electric auxiliary gear shifting transmission comprises: a flywheel shock absorber, an auxiliary motor, a speed regulation planetary gear set, a planet row front input shaft, a first input shaft, a second input shaft and at least one output shaft which are arranged between the transmission and an engine; a mechanical speed change system arranged between the input shaft and the output shaft; a first clutch used for controlling torque connection or interruption between the planet row front input shaft and the first input shaft; and a second clutch used for controlling torque connection or interruption between the planet row front input shaft and the second input shaft. The transmission has the advantages that the auxiliary functions of the speed regulation planetary gear set and the auxiliary motor are utilized, and the clutch is matched for cooperative wriggling, starting and gear shifting; and the problems that an existing transmission is low in transmission efficiency and too high in transmission oil temperature under the creeping and starting working conditions and the problems of power fluctuation, gear shifting impact, gear shifting jerking, low transmission efficiency during gear shifting, insufficient acceleration power in a low gear area and frequent gear shifting in a medium-high gear area during multi-gear speed changing and gear shifting are solved, and the reliability of the transmission is improved.
Description
technical field [0001] The invention belongs to the field of automobile transmissions, in particular to an automatic shift transmission. Background technique [0002] The transmission is one of the three key components of the car, and its performance directly determines the power performance, transmission efficiency, fuel economy, shifting smoothness and comfort of the car. At present, the structure of automatic transmission mainly includes multi-speed transmissions such as mechanical automatic transmission AMT (Automated Mechanical Transmission), dual clutch transmission DCT (Double Clutch Transmission), hydraulic automatic transmission AT (Automatic hydraulic Transmission) and continuously variable automatic transmission CVT (Continuously Variable Transmission). Transmission), each of these transmission structures has technical advantages, but also has its own structural problems: for example, in creeping and starting conditions, since the vehicle speed is lower than the d...
