Example Embodiment
[0007] Specific implementation mode 1: Combination figure 1 To describe this embodiment, the auto-coupling continuously variable transmission of this embodiment consists of a torque converter 1, an intermediate shaft 2, a differential planetary row 3, a long hollow shaft 4, a brake 5, a second one-way clutch 6, and a third one-way clutch. 7. The variable speed planetary row 8 and the two-way clutch 9 are composed; the torque converter 1 is composed of a pump wheel 1a, a turbine wheel 1b, a guide wheel 1c, a first one-way clutch 1d and a short hollow shaft 1e. The differential planetary row 3 It is composed of a differential sun gear 3a, a differential planet gear 3b, a differential planet carrier 3c and a differential ring gear 3d. The differential planet row 3 is arranged in the torque converter 1, and the torque converter 1 is sleeved on the intermediate shaft 2, the variable speed planetary row 8 consists of a front row sun gear 8a, a rear row sun gear 8b, a front row planet ca...
Example Embodiment
[0008] Specific implementation manner two: combination figure 1 This embodiment will be described. In this embodiment, between the intermediate shaft 2 and the long hollow shaft 4, between the long hollow shaft 4 and the short hollow shaft 1e, between the front planet carrier 8c and the intermediate shaft 2, and the rear planet carrier 8d and Between the intermediate shafts 2 and between the torque converter 1 and the intermediate shaft 2 are rotation fits. Such a setting can ensure smooth and reliable rotation of the transmission. Others are the same as the first embodiment.
[0009] The working principle is: The self-coupled continuously variable transmission of the present invention is mainly driven by coaxial gears, supplemented by hydraulic transmission. The power is divided into two paths and transmitted to the rear planet carrier 8d for synthesis and output. The gear transmission route is differential. The ring gear 3d and the engine are at the same speed, transmitted to th...
