  • Patent number: 8424405
    Abstract: A mainshaft assembly for a gearbox includes a mainshaft (44) and drive gears (31, 36) carried for rotation about the mainshaft. First and second hubs (50, 50?) are associated with respective drive gears, each hub being operable to selectively couple or uncouple with the drive gear causing it to rotate with the hub or with respect to the hub. A drive connection mechanism (42, 64, 66) associated with each hub selectively connects the hub to the mainshaft. Upon connection of the hubs to the drive gears, the drive connection operates to connect one or other of the hubs to the mainshaft when torque is applied to the mainshaft in a first direction or an opposite direction. This enables a gear ratio to be selected by reversing the torque being handled by the gearbox.

  • Patent number: 8408086
    Abstract: An automated shift control device suppresses overload of the shift motor and reduces the time from beginning to completion of a gear shifting operation. A transmission has a plurality of pairs of speed change gears and a gear selecting mechanism. A shift motor drives the gear selecting mechanism. A shift power transmission mechanism transmits power from the shift motor to the gear selecting mechanism. A torque limiter has a third reduction gear and a third shaft forming a part of the shift power transmission mechanism. The torque limiter transmits power from the shift motor as torque. When the transmitted torque is not more than a predetermined limit torque, the third reduction gear co-rotates with the third shaft. When the transmitted torque exceeds the predetermined limit torque, the third reduction gear rotates relative to the third shaft to limit the transmitted torque to the predetermined limit torque or less.
