Embodiment Construction

[0020] The present invention will be further described below in conjunction with the examples, but the present invention is not limited.

[0021] Such as Figure 1-4 As shown, the two-speed automatic transmission of the present invention includes a motor, a mechanical automatic transmission, a hydraulic shift actuator that is placed outside the transmission and controls the gear position through a shift fork rod extending into the casing, and a transmission control unit; The feature is that the motor and the transmission are integrated, wherein the motor housing 3 and the transmission housing 6 are integrated, and the right end cover 21 of the motor is also the left end cover of the transmission. The motor shaft 1 is also the transmission input shaft at the same time, and the input shaft directly gears the constant meshing gear 17 and is fixed on the motor shaft 1 . The transmission input shaft 1 is supported in the transmission output shaft 8 through a needle bearing, which ...

Abstract

The invention relates to a two speed automatic transmission which is characterized in that an electric motor and a transmission box are linearly integrated into a whole, a motor shaft is a transmission input shaft, the transmission input shaft is supported in a bearing of a transmission output shaft by a needle bearing or is connected with the transmission output shaft by splines, and a speed coupling shaft is arranged between a transmission intermediate shaft and the transmission output shaft; a transmission input shaft direct gear constant mesh gear is fixed on the motor shaft, and a transmission intermediate shaft direct gear constant mesh gear is meshed with the transmission input shaft direct gear constant mesh gear; an output shaft speed coupling gear fixed on the transmission output shaft and a coupling shaft speed coupling gear fixed on the speed coupling shaft are maintained meshed commonly; the speed coupling shaft is provided with an output shaft encoder, and an intermediate shaft encoder is arranged at the tail end of the transmission intermediate shaft. According to the two speed automatic transmission, the problem of power failure in the shifting process is solved, no obvious speed reduction is generated in the shifting process, the comfort in shifting is enhanced, the fuel economy is improved at the meantime, and the fuel consumption in the shifting process is reduced.

Description

technical field [0001] The invention relates to a mechanical power transmission speed change device, in particular to an electric-driven mechanical two-speed automatic speed change device suitable for automobiles. Background technique [0002] Manual transmission (MT) needs to move the shift lever by hand to change the meshing position of the gears in the transmission and change the transmission ratio to achieve the purpose of shifting. It is necessary to step on the clutch when shifting the gear lever, which increases the complexity of vehicle operation. Mechanical transmissions require human intervention and are difficult to meet people's requirements. Automatic transmission (AMT) not only has the advantages of automatic transmission of hydraulic automatic transmission, but also retains the advantages of high efficiency, low cost, simple structure and convenient processing of the original manual transmission gear transmission. AMT is modified on the existing mechanical t...
