Abstract
The invention relates to a three-countershaft type active transmission device of a vehicle, which is characterized in that the device comprises a motor and an axis fixed type gear box, wherein the axis fixed type gear box comprises an input shaft, a power output main shaft and three independent countershafts; the first countershaft and the second countershaft are in driving connection with the main shaft and are respectively supported by at least one speed changing gear and a corresponding synchronous switching device; the input shaft is equipped with at least one synchronizer gear; the synchronizer gear is meshed with the speed changing gears which are respectively arranged on the first countershaft and the second countershaft; the third countershaft is in driving connection with the motor and is provided with a first torque transmission path which is disposed between the third countershaft and the input shaft and a second torque transmission path which is disposed between the third countershaft and at least one countershaft selected from the first countershaft and the second countershaft; and the first countershaft and the second countershaft can be broken through the synchronous switching device. Compared with the prior art, the three-countershaft type active transmission device of a vehicle provided by the invention has the advantages that the axial space scale is small, the structure is simple, the power interruption phenomenon during the shifting process is reduced, the structure is compact and the installation and distribution of the device to the whole vehicle are convenient.
Description
technical field [0001] The invention relates to an active transmission device for a vehicle, in particular to a three intermediate shaft type active transmission device for a vehicle. Background technique [0002] Among the main types of transmissions in the field of traditional automobile transmission technology, fixed-axis manual transmission (MT) has high transmission efficiency, convenient manufacturing and processing, low cost and high reliability, so it has always been the mainstream technology in the domestic vehicle transmission market. However, MT has some problems in the operation and use of the vehicle, especially in special driving conditions such as starting on a slope. Compared with other types of transmissions, it is inconvenient to operate; in addition, poor timing of shifting will increase fuel consumption and engine wear. The operator's operation burden is heavy. In the known art, it is proposed to replace the manual shift operation with an automatically o...
