Transmission integrating manual shift mode and automatic shift mode

Abstract

The invention provides a transmission integrating a manual shift mode and an automatic shift mode. The transmission integrating the manual shift mode and the automatic shift mode comprises a gear shifting control mechanism and a transmission mechanism, wherein the gear shifting control mechanism is a mechanical structure; the transmission mechanism comprises a first power input shaft and a secondpower input shaft, the first power input shaft provides power through a hydraulic torque converter to be used for driving a power output shaft to rotate at a low speed, the second power input shaft provides power through a mechanical clutch to be used for driving the power output shaft to rotate at a high speed. The transmission is characterized in that when the automobile runs at a low speed, thespeed is automatically changed, so that the starting and acceleration of the automobile is ensured to be smooth, the complicated operation in the frequent parking and starting process is avoided, thedriving operation is simple, and the labor intensity of a driver is reduced; when the automobile runs at a high speed, the speed is changed through manual shifting, and therefore the operation feeling under the manual shift mode is achieved, the pleasant sensation is achieved during driving, and meanwhile, the manual shift mode has higher fuel economic performance than the automatic shift mode; and the gear shifting control mechanism adopts the mechanical structure, so that the transmission has good reliability.

Description

technical field [0001] The invention relates to the technical field of vehicle components, in particular to an automatic manual transmission. Background technique [0002] At present, existing automobile transmissions generally have three types: manual transmission, automatic transmission and automated manual transmission. Manual transmission is simple in structure, reliable in performance, cheap in price and relatively good in fuel economy, but it is cumbersome to operate and requires high driving skills, especially in the urban driving process, frequent starting and shifting, the driver's labor intensity is high, and it is easy to operate unskilled Cause the engine to stall; the automatic transmission is easy to operate, especially suitable for driving in urban areas, but in the suburbs and on the road, the driving control is not strong, and the fuel economy performance is relatively poor, the structure is complex, and there are complicated hydraulic and electronic control...

Problems solved by technology

Manual transmission is simple in structure, reliable in performance, cheap in price and relatively good in fuel economy, but it is cumbersome to operate and requires high driving skills, especially in the urban driving process, frequent starting and shifting, the driver's labor intensity is high, and it is easy to operate unskilled Cause the engine to stall; the automatic transmission is easy to operate, especially suitable for driving in urban areas, but in the suburbs and on the road, the driving control is not strong, and the fuel economy performance is relatively poor, the structure is complex, and there are complicated hydraulic and electronic control parts. More expensive, high maintenance costs

[0003] And although the existing automated manual automatic transmission has both automatic mode and manual mode, its manual mode is to complete the gear shift by manually controlling the electronic control part, and the sense of control is not strong. Most car owners basically do not need to shift gears in manual mode. In addition, the function is idle and wasted. At the same time, the gear shift control is also controlled by a combination of hydraulic pressure and electric control. The structure is complex, the price is relatively expensive, and the maintenance cost is high.
