Embodiment Construction

[0018] An automatic transmission with power compensation of the present invention is based on the traditional AMT gearbox, adding an auxiliary clutch 9, a vehicle speed sensor (not shown in the figure) and changing the original input shaft to be composed of a sleeve shaft 3 and a mandrel 2 Dual-shaft structure to realize uninterrupted power when shifting gears.

[0019] see figure 1 , the original input shaft has been modified into a biaxial structure consisting of a sleeve shaft 3 and a mandrel 2, wherein the sleeve shaft 3 is sleeved outside the mandrel 2, and one end of the mandrel 2 is fixedly connected with the output shaft of the original engine 20 (such as through spline fixed connection), the other end is fixedly connected with the auxiliary clutch 9, and this end is also fixedly sleeved with a high-grade gear (the fixed sleeve method is a detachable sleeve, and it can also be achieved by an integrally formed structure. The socketing of the dismounting method, such a...

Abstract

The invention discloses an automatic transmission with power compensation, mainly comprising engine, main clutch, input shaft, assistant shaft, electronic control cell, clutch control mechanism, shift control mechanism and shift sensor. Especially it also comprises assistant clutch and speed sensor. Sleeve shaft and core shaft are set on said input shaft. The sleeve shaft is set out of the core shaft. One end of the sleeve shaft is fixed with the main clutch and at the other end all shift gears are fixed respectively. One end of the core shaft is fixed with the output shaft of engine. The other end is fixed with the assistant clutch and at the other end high shift gear is set. The assistant clutch is fixed with the high shift gear and the speed sensor is connected with the electronic control component in current. The engine is connected with the electronic control component in current. The electronic control component can control electrifying current of engine according to the speed change during shift period. The transmission is provided with simple structure and high transmission efficiency.

Description

technical field [0001] The invention relates to an automatic transmission (abbreviated as AMT) for automobiles, in particular to an automatic transmission with power compensation with simple structure and high transmission efficiency. Background technique [0002] At present, in general automobiles, during the shifting process of the transmission, in order to reduce the impact load of the transmission gear and prevent the overload of the transmission system, the automobile realizes the shift through the separation and engagement of the clutch, and the power transmission is temporarily interrupted between the separation and engagement of the clutch. The phenomenon. At this time, the speed of the vehicle will slow down as the power is interrupted, until the gear shift is completed, the clutch will be re-engaged, and the speed of the vehicle will suddenly accelerate with the output of power. In this process, if it is a traditional manual transmission, the driver has the awaren...
