Transmission

Abstract

The invention relates to an automatic transmission capable of outputting power as far as possible in a gear shift process. The front end of an outer shaft I provided by the invention is connected and fixed with a shell; the rear end of the outer shaft I is connected with the front end of a protrusion of an inner shaft I; the rear end of the inner shaft I is connected with the front end of a shaft II; an odd shaft and an even shaft are respectively installed in the shell and are positioned at the two sides of the shaft II; the odd shaft and the even shaft are all provided with two unidirectional clutches; a unidirectional clutch is externally provided with a band-type brake, and the other unidirectional clutch is externally provided with a constant mesh gear; the unidirectional clutches on the odd shaft and the even shaft are externally and respectively provided with a constant mesh gear which is meshed with the gear of an inner shaft I; and the unidirectional clutch which is externally provided with the constant mesh gear on the odd shaft or the even shaft is internally provided with a synchronizer between the odd shaft and the even shaft. According to the invention, in the process of gear shift by combining with the clutches, the original gear still works, the transmission outputs power as far as possible in the gear shift process, when an automobile slides backwards after start and stop in ascent, the automobile is locked automatically without the match of a brake.

Description

technical field [0001] The invention belongs to an automatic transmission in a vehicle, in particular to an automatic transmission that outputs 100% of the power of the transmission during the shifting process. Background technique [0002] In the traditional automatic transmission system, when shifting gears, the clutch must be disengaged first, then the transmission must be replaced with the corresponding gear, and then the clutch should be combined. In this way, the power will be reduced and the smoothness will be poor during the shifting process. However, although the dual clutch saves the time for shifting gears of the gearbox when shifting gears, it still needs to completely separate the clutch of one gear and then combine the clutch of another gear.

Problems solved by technology

[0002] In the traditional automatic transmission system, when shifting gears, the clutch must be disengaged first, and then the transmission should be replaced with the corresponding gear, and then the clutch should be combined. In this way, the power will be reduced and the smoothness will be poor during the shifting process.

However, although the dual clutch saves the time for shifting gears of the gearbox when shifting gears, it still needs to completely separate the clutch of one gear and then combine the clutch of another gear. This will still cause the problem of power interruption. People often use One clutch is not completely disengaged, and the other clutch starts to combine to achieve uninterrupted power output, but the result of this will make the shifting operation very complicated, increase the cost of the automatic transmission operating system and reduce the life of the clutch. Moreover, there is still a short-term power decline during the shifting process. When the load is heavy and the slope is large, it will cause the vehicle to fail to drive normally, stall, slip and other accidents. This is something that the current transmission cannot do.
