Problems solved by technology

[0002] Automotive shifting technology, especially automatic transmission shifting technology, can be divided into hydraulic transmission shifting transmission (AT), steel belt continuously variable transmission (CVT), automatic gear manual transmission (AMT), etc.; They have their own advantages and disadvantages. The disadvantage of the hydraulic transmission shifting transmission (AT) is that the transmission efficiency is low. The steel belt transmission (CVT) is prone to heat and is relatively delicate. It is not suitable for high-power applications. The manual transmission (AMT) has high transmission efficiency, but the computer-controlled shifting is too complex and technically demanding, and there is a sense of frustration when shifting gears

[0027] Figure 8 In this embodiment, there are six forward gears and six reverse gears, the power from the engine is input to the total input shaft (SR) of the compound planetary gear set gearbox, and the input shaft (SR) is coaxially provided with an input gear A gear (103) and an input reverse gear (104), and a gear synchronizer (106) is also arranged between the two gears for selecting forward gear, reverse gear or neutral gear. When the gear synchronizer (106) is connected to the reverse gear (104), the input shaft (SR) meshes with the reverse gear (104), the reverse gear (104) meshes with the reverse idler gear (105), and the reverse idler gear (105) The input shaft (11a) of the first compound planetary gear unit is engaged, so that the power is transmitted to the compound planetary gear unit; when the gear synchronizer (106) is connected to the input gear (103), the input shaft (SR) meshes with the input gear (103), the input gear (103) meshes with the input shaft (11a)...

Abstract

The invention relates to an automobile gearbox, in particular to a combined type planetary gear set gearbox which is high in power transmission efficiency, gentle in gear shifting and multiple in gear, and is capable of partially replacing a traditional automatic gearbox. The input end of each combined type planetary gear unit in the combined type planetary gear set gearbox is connected with a power selection input unit, power output by an engine is input to the combined type planetary gear units through the power selection input units, speed changing shifting is achieved by controlling the combined type planetary gear units, speed changing shifting can be effectively performed by using a single combined type planetary gear unit, and two or more combined type planetary gear units can obtain more output gears.

Description

technical field [0001] The present invention relates to the technology of mechanical transmission gearbox, in particular, when applied to automobile gearbox, high-quality shifting of power transmission can be realized simply and effectively, and automatic shifting or manual shifting can be easily realized. Background technique [0002] Automotive gear shifting technology, especially automatic transmission shifting technology, can be divided into hydraulic transmission shifting transmission (AT), steel belt drive continuously variable transmission (CVT), automatic gear shifting manual transmission (AMT), etc.; They have their own advantages and disadvantages. The disadvantage of the hydraulic transmission shift transmission (AT) is that the transmission efficiency is low. The steel belt transmission infinitely variable transmission (CVT) is prone to heat and is more delicate, not suitable for high-power applications. The geared manual transmission (AMT) has high transmission ...
