Automatic gearbox of automobile

Abstract

The invention belongs to the field of gearboxes, and particularly relates to an automatic gearbox of an automobile. The automatic gearbox comprises an A gear column body, a B gear column body and a reverse gear system body, a power input shaft and a power output shaft are arranged on the A gear column body, the power input shaft is connected with the output end of an engine rotating clockwise, a first driving gear, a second driving gear, a third driving gear and a fourth driving gear are arranged in the A gear column body, a first ratchet, a second ratchet and a third ratchet which are clockwise in one direction and sequentially inserted in the first driving gear, the second driving gear, the third driving gear and the fourth driving gear are further arranged in the A gear column body, the overall structure of the A gear column body is that the first driving gear and the first ratchet are integrated, the first ratchet is connected with the second driving gear, and the second driving gear and the second ratchet are integrated. According to the automatic gearbox, the service life of the gearbox is prolonged, the power loss is relatively small, and the balanced power demand can make the engine no longer powerless.

Description

technical field [0001] The invention relates to the technical field of gearboxes, in particular to an automatic gearbox for automobiles. Background technique [0002] Among the existing ordinary family cars, no matter at home or abroad, automatic transmission cars commonly use three types of automatic transmissions: dual-clutch transmission, AT transmission and CVT transmission. There are shifting jams, AT gearboxes have problems such as low energy transmission efficiency and complicated process flow, and due to structural reasons, the power transmission of Japanese CVT automatic gearboxes is limited and cannot withstand high-horsepower driving. Contents of the invention [0003] The purpose of the present invention is to solve the shortcoming existing in the prior art, and propose a kind of automobile automatic transmission. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] An automatic transmission f...

AI Technical Summary

Problems solved by technology

[0002] In the existing ordinary family cars, no matter at home or abroad, automatic transmission cars commonly use three types of automatic transmissions: dual-clutch gearbox, AT gearbox and CVT gearbox. These three automatic gearboxes have their own advantages and disadvantages. There is a phenomenon of shifting stuck, and the AT gearbox has problems such as low energy transmission efficiency and complicated process flow. Due to structural reasons, the power transmission of the Japanese CVT automatic gearbox is limited and cannot withstand high-horsepower drive.
