Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] A special mechanical automatic transmission for planetary AMT, the present invention can be divided according to the number of intermediate shafts as follows: figure 1 with figure 2 single intermediate shaft as shown, and image 3 with Figure 4 The double countershaft structure shown can be divided into ring gear output and bracket output according to the different functions of the bracket and ring gear in the planetary structure. Here we take the conventional single countershaft ring gear output power as an example to illustrate:

[0017] see figure 1 , a mechanical automatic transmission dedicated to a planetary AMT, comprising a conventional transmission internal structure, a clutch device and a planetary mechanism, the automotive mechanical automatic transmission AMT passes the output shaft 4 of the conventional transmission through a ...

Abstract

The invention relates to a special planetary automated mechanical transmission (AMT), which comprises an interior structure of a conventional transmission, a clutch device and a planetary mechanism. In the special AMT of an automobile, an output shaft of the conventional transmission is connected with a sun wheel of the planetary mechanism through the clutch device; the sun wheel of the planetary mechanism can be connected with a planetary bracket or a gear ring of the planetary mechanism by the clutch device; and an intermediate shaft is connected with the planetary bracket or the gear ring of the planetary mechanism by a gear pair or a belt wheel. When the transmission of the automobile is required to shift gears, the output shaft is disconnected from the sun wheel by the clutch device, the sun wheel and the planetary bracket or the gear ring are connected into a whole, the gear ring or the planetary bracket continuously outputs power, the output shaft of the transmission no longer forms a power transfer action, and a gear shifting mechanism on the output shaft of the transmission can shift the gears freely, so the problem of power interruption in the process of gear shifting of the AMT of an automobile is solved, and mechanical interference is avoided in the process of gear shifting.

Description

technical field [0001] The invention belongs to the technical field of key components of an automobile transmission system, and relates to a special mechanical automatic transmission for an automobile planetary AMT. Background technique [0002] The working process of automobile AMT mainly replaces human sensory organs with various sensors, replaces human hands and feet with manipulation control mechanism, replaces human brain with ECU, and simulates the shifting process of a skilled driver to automatically complete the entire shifting process of the car. block process. The ATM is based on the traditional manual mechanical transmission and is composed of an electronic control device. The control objects of AMT include engine, clutch and transmission, and they all adopt the structure of traditional power transmission system. What the AMT adds is the electronic control unit and the control actuator. ECU is the control core part of AMT, which is mostly composed of large-scal...
