Automatic transmission

Abstract

The invention relates to an automatic transmission. The automatic transmission comprises a shell, a transmission master controller, an electric control hydraulic distributor and a clutch, wherein thetransmission master controller is connected with the electric control hydraulic distributor through a hydraulic pump; the clutch is located in the shell; the electric control hydraulic distributor communicates with a hollow shaft oil channel in the clutch through a hydraulic pipeline; a power input shaft and a power output shaft are correspondingly arranged on two sides of the shell; the other endof the power input shaft is connected with an engine; and the power output shaft is connected with a differential box outside the housing. The automatic transmission is reasonable in structural design, easy to manufacture, low in production cost, simple in internal structure, small in size, light in weight and durable on the whole.

Description

Technical field: [0001] The invention relates to an automatic gearbox. Background technique: [0002] There are roughly the following types of automatic transmissions for small passenger cars on the market: [0003] The disadvantages of AT gearboxes are large size, strong shifting frustration, high fuel consumption, high production costs, and the core technology is blocked by foreign countries. [0004] CVT infinitely variable gearbox requires extremely high processing precision, high production cost, cannot withstand large torque, cannot match high-horsepower models, short maintenance cycle, internal transmission steel belt is easy to break, and the entire gearbox is scrapped. [0005] The AMT electronically controlled mechanical automatic shift transmission has a slow shifting action and a strong sense of frustration when driving. It cannot meet the modern high-standard automobile production requirements, so it does not have any advantages. [0006] DCT dual-clutch elect...

AI Technical Summary

Problems solved by technology

[0003] The disadvantages of AT gearboxes are large size, strong shifting frustration, high fuel consumption, high production costs, and the core technology is blocked by foreign countries

[0004] CVT infinitely variable gearbox requires extremely high production and processing precision, high production cost, cannot withstand large torque, cannot match high-horsepower models, short maintenance cycle, and the internal transmission steel belt is easy to break, causing the entire gearbox to be scrapped

[0005] AMT electronically controlled mechanical automatic shifting gearbox, the shifting action is slow, and the feeling of frustration is extremely strong when driving. It cannot meet the modern high-standard automobile production requirements, so it does not have any advantages.

[0006] DCT dual-clutch electronically controlled mechanical automatic transmission has high production costs and strict requirements on the control software of the transmission. Otherwise, the coordination of various components will not be precise enough to achieve rapid shifting action. Only some large foreign car companies have the ability to produce

[0007] Sequential shift gearboxes are more expensive to produce! And the service life is short, and it has extremely high requirements on the driver's driving skills. Due to its high production cost, it can only be used in racing cars or super sports cars at present, and it cannot be popularized in civilian cars at all.

[0008] MT manual shift gearbox, in order to achieve a comfortable ride, must require the driver's driving skills to be excellent, because the operation process is complicated, and the driver is prone to fatigue when used for a long time, this gearbox is only assembled in low-end models , has been gradually eliminated by the market
