Problems solved by technology

However, the three-axis gearbox uses two output shafts, and both output shafts must be meshed with the input shaft and the reducer. In order to prevent the gears on the two output shafts from interfering with each other, the center distance between the shafts must be appropriately increased. , so the required meshing gears are relatively large, resulting in heavy mass, large volume, and loud noise of the gearbox, and the NVH performance of the gearbox is poor

Abstract

The invention relates to an electronic control mechanical type speed changing box structure, and belongs to the technical field of speed changing boxes. The electronic control mechanical type speed changing box structure comprises an input shaft, an output shaft and a reverse gear shaft. The input shaft is provided with a plurality of tap position driving gears. The output shaft is provided with a plurality of tap position driven gears meshed with the tap position driving gears, a transition driving gear and a reduction gear. The reverse gear shaft is fixedly provided with a reverse gear driving gear and is sleeved with a reverse gear driven gear which is connected with a reverse gear synchronizer. The electronic control mechanical type speed changing box structure further comprises a middle shaft, a first motor shaft and a second motor shaft. According to the electronic control mechanical type speed changing box structure, the first motor shaft connected with a motor directly carries out pure electric power input or provides power supplement for the speed changing box.

Description

technical field [0001] The invention belongs to the technical field of gearboxes, and in particular relates to an electronically controlled mechanical gearbox structure. Background technique [0002] As a typical energy-saving and environment-friendly product, hybrid vehicles are gradually attracting widespread attention from the world. The key of the hybrid is the hybrid system, its performance is directly related to the performance of the hybrid vehicle. However, these hybrid power systems currently have the problems of large structural volume, difficulty in vehicle layout, complex structure and high cost. At the same time, for a six-speed transmission for a vehicle, a transverse three-shaft transmission is often used. A three-shaft gearbox has one input shaft and two output shafts. The gears can be reasonably arranged on the three shafts, so the axial dimension is small, which is conducive to the adjustment and arrangement of the whole vehicle, the supporting distance ...
