技术领域technical field
本发明属于变速箱技术领域，具体涉及一种电控机械式变速箱结构。The invention belongs to the technical field of gearboxes, and in particular relates to an electronically controlled mechanical gearbox structure.
背景技术Background technique
混合动力车辆作为一种典型的节能环保产品，正逐步受到世人的广泛关注。混合动力的关键是混合动力系统，它的性能直接关系到混合动力汽车的性能。但目前这些混合动力系统存在结构体积大导致整车布置困难和结构复杂成本高的问题。同时，对于车用六挡变速器而言，经常会采用横置三轴式变速箱。三轴式变速箱具有一根输入轴、两根输出轴。齿轮可合理布置于三根轴上，因此轴向尺寸小，有利于整车调整布置，支撑距离小，变速箱刚度好。但三轴式变速箱采用了两根输出轴，两根输出轴均要与输入轴和减速器啮合，为了使两输出轴上的齿轮不相互干涉，各轴之间的中心距必须适当变大，因此所需啮合齿轮也相应较大，导致变速箱的质量重、体积大、噪声大，变速箱的NVH性能较差。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 is small, and the rigidity of the gearbox is good. 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 also correspondingly larger, resulting in heavy mass, large volume, and high noise of the gearbox, and the NVH performance of the gearbox is poor.
