Example Embodiment
[0042] See Example 1 figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , An automatic transmission device containing a torque-limiting clutch, comprising a driving shaft 1 and a driven shaft 2. The driving shaft 1 and the driven shaft 2 are respectively provided with a high gear pair and a low gear pair corresponding to the constant meshing. The high-speed driving gear 4 of the high-speed gear pair is rotatably connected to the driving shaft 1. A normally closed bevel disc friction torque-limiting clutch is provided between the high-speed driving gear 4 and the driving shaft 1. The loading spring 63 is connected between the end surface of a journal of the driving shaft 1 and one end surface of the driving cone 61 of the friction torque limiting clutch. An end bearing 64 is provided between the driving cone 61 and the loading spring 63; the driving cone 61 A torque transmission structure for power transmission is also provided between the driving shaft 1 and the driving sha...
Example Embodiment
[0053] See Example 2 Image 6 , Figure 7 , The low-speed driving gear 3 and the driving bevel 61 are formed as one body; the end bearing 64 is connected between the loading spring 63 and the low-speed driving gear 3; the driving bevel 61 and the driving shaft 1 A torque transmission structure for power transmission is provided in between. The torque transmission structure is an end face cam pair structure, which includes a cam pair active member 11 fixedly connected to the driving shaft 1, and is integrally formed on the active cone 61 of the friction torque-limiting clutch The cam sub-driven member 41 of the cam sub-active member 11 and the cam sub-driven member 41 are provided with V-groove cam surfaces on their opposite end surfaces. The protruding parts of the end surfaces of the active member 11 and the passive member 41 of the cam pair are corresponding to the V The recesses of the grooves are complementary, and the slopes on both sides of the V groove are symmetrical. T...
Example Embodiment
[0056] Example 3 see Figure 8 , The low-speed driving gear 3 is coaxially fixedly connected to the driving shaft 1; the power input gear 12 is fixedly connected to the driving cone 61 of the friction torque-limiting clutch; the driving cone 61 is connected to the driving shaft 1 A torque transmission structure with a spiral spline fitting structure is also provided between the power input gear 12 and the driving shaft 1; the loading spring 63 is connected between the driving cone 61 and the shoulder of the driving shaft 1.
[0057] The rest of the structure of this embodiment is the same as that of Embodiment 1, and will not be repeated here.
