Problems solved by technology

This lubrication method is effective, safe and reliable, but the disadvantage of this forced lubrication is that it requires additional pressure oil for lubrication, that is, it needs to consume energy to transport the oil to the position where the synchronizer is located
Therefore, in the above-mentioned dual-clutch automatic transmission, in order to meet the lubrication requirements of the synchronizer, a large amount of energy needs to be consumed, resulting in relatively large fuel consumption of the dual-clutch automatic transmission.

Abstract

The invention discloses a double-clutch automatic transmission which comprises a gearbox shell and a gear shaft mechanism installed in the gearbox shell. The gear shaft mechanism comprises a synchronizer and further comprises a synchronizer lubricating mechanism fixed into the gearbox shell. The synchronizer lubricating mechanism comprises a lubricating shell, the lubricating shell is provided with a lubricating oil collection cavity and a lubricating oil outlet, the lubricating oil collection cavity is communicated with the lubricating oil outlet, and in the vertical direction, the lubricating oil outlet is opposite to the synchronizer in position. According to the double-clutch automatic transmission, original lubricating oil in the gearbox shell is collected through the lubricating shell, and the lubricating oil is guided to flow to the synchronizer again so as to achieve recycling of the lubricating oil. Besides, the lubricating effect of the synchronizer is guaranteed without the need of extra lubricating oil. Thus, the oil consumption of the double-clutch automatic transmission is low. The invention further discloses an automobile.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a dual-clutch automatic transmission. The invention also relates to a motor vehicle. Background technique [0002] At present, more and more automobile factories have begun to develop dual-clutch automatic transmissions, which are different from manual transmissions in terms of lubrication systems. Because there are some components with high heat generation inside the dual clutch automatic transmission, such as dual clutches, hydraulic modules, oil pumps, etc., the lubrication system of the traditional dual clutch automatic transmission basically adopts the form of forced lubrication. [0003] As for the synchronizer, the dual-clutch automatic transmission is also different from the manual transmission. Specifically, the synchronizer of the manual transmission adopts the form of splash lubrication. Since the internal space of the manual transmission is relatively large, the...
