Embodiment 1
[0026] Embodiment 1: The technical scheme that the present invention proposes obtains by improving on the basis of the automatic manual transmission of an automobile. Figure 1 is a schematic diagram of an automotive automatic manual transmission.
[0027] In this AMT system, the gearbox is a two-shaft five-speed gearbox, and automatic shifting can be realized through the control of the selection, shift actuator and clutch actuator.
[0028] Fig. 2 is a schematic diagram of the principle of implementing the technical solution of the present invention by improving the AMT system in Fig. 1 . Compared with Fig. 1, there is no change in the car main clutch and its operating mechanism. The gearbox shift control mechanism is also similar to AMT and can basically be shared. Inside the gearbox, all shift synchronizers were removed, easy-to-engage sleeves were used for shifting, and a double-sided shift clutch was added. The fixed disc A of the shift clutch is fixed on the first shaf...
Embodiment 2
[0043] Embodiment 2: The gearbox is a three-shaft five-speed gearbox:
[0044] Inside the gearbox, an easy-to-engage sleeve is used to shift gears, and a double-sided shift clutch is added. The fixed disc (A) of the shift clutch is fixed on the intermediate shaft of the gearbox, and there are two floating discs (B) on both sides of the fixed disc. ) and (C), the floating disc (B) and the cylindrical spur gear (B1) are connected as a whole, and the two are vacantly sleeved on the intermediate shaft of the gearbox, and the gear (B1) meshes with the gear (B2) to form an upshift gear pair, The gear (B2) is fixed on the second shaft of the gearbox;
[0045] The floating disc (C) is connected with the cylindrical spur gear (C1) as a whole, and the two are sleeved on the intermediate shaft of the gearbox. The gear (C1) meshes with the gear (C2) to form a downshift gear pair, and the gear (C2) is fixed on the on the second shaft of the gearbox.
[0046] The embodiment shown in Fig. ...
