Problems solved by technology

However, the master and driven friction plates of the multi-plate clutch in the disengaged state slip through each other due to the lubricating oil, resulting in relatively large frictional resistance, which reduces the transmission efficiency of the transmission accordingly.

Abstract

The invention belongs to transmissions, in particular relates to a transmission with three shafts and two clutches. The transmission with three shafts and two clutches is characterized by comprising the two clutches, two input shafts and one output shaft; the two clutches are driven by an engine in a gear driving or belt driving manner and are respectively connected with the corresponding input shafts; a drive gear set with odd gears is arranged on one input shaft, while drive gear sets with even gears are arranged on the other input shaft; a driven gear set is arranged on the output shaft; the drive gears of the two input shafts share a corresponding driven gear; a drive gear of a reverse gear is arranged on one input shaft; a driven gear of the reverse gear is arranged on the other input shaft and meshed with the drive gear of the reverse gear; a joint gear ring of a parking mechanism is fixedly connected with a box and matched with a synchronous device of the output shaft; and a parking function is realized by pulling a shifting fork by a gear shifting pull wire. The transmission with three shafts and two clutches is compact in structure and low in cost; besides, the transmission does not employ a concentric shaft, therefore, the axial length of the transmission is reduced, the rigidity of the system is enhanced, and the performance is reliable.

Description

technical field [0001] The invention belongs to the category of transmissions, in particular to a three-shaft double-clutch transmission. Background technique [0002] The dual-clutch transmission realizes the shifting action through the matched switching of the two clutches, and the shifting is fast and smooth. During the shifting process, the power of the engine is continuously transmitted to the wheels to realize power shifting and ensure that the vehicle has good acceleration performance. The dual-clutch transmission is developed based on the parallel-shaft manual transmission, and it inherits many advantages of the manual transmission, such as high transmission efficiency, compact installation space, light weight, and low price. [0003] At present, there are mainly three types of dual-clutch transmission structures: dual-clutch single-shaft output, combined clutch single-shaft output and combined clutch dual-shaft output. The dual-clutch single-shaft output maximizes...
