Abstract: Torque is transmitted from an electric motor to an output unit through different gear trains depending on direction of rotation of the electric motor. The drive unit includes an electric motor, a first gear train, a second gear train, a third gear train, and a moving mechanism. The first gear train includes a first drive gear, a first driven gear, and a clutch member. The clutch member moves inside the first driven gear and receives torque transmitted from the first driven gear. The second gear train transmits to an output unit the torque transmitted from the first gear train. The third gear train transmits to the output unit the torque transmitted from the first gear train. The moving mechanism axially moves the clutch member toward the second drive gear when the electric motor is forwardly rotated and toward the third drive gear when the electric motor is reversely rotated.

Abstract: A constant mesh gear transmission has an input shaft (21, 22), two layshafts (31, 35) and an output shaft (23). Gear wheels are selectively connectable to shafts to provide forward and reverse speed ratios. Reverse speed ratio is via a sleeve (85, 86) of a reverse layshaft (35). The sleeve can also re-circulate torque to a forward layshaft (31) to provide an additional low forward speed ratio. Two sleeves and two additional low forward speed ratios are disclosed.

Abstract: A reverse idler support article includes a reverse idler support body that has a disk member, a plateau and a hollow cylinder. The disk member is connected to and in facial contact with the plateau that projects from a first disk member surface and the hollow cylinder that projects from a second disk member surface to define an interior space. The disk member and the plateau have an offset hole formed therethrough that is in communication with the interior space. The offset hole is oriented offset from a central axis of the reverse idler support body which extends generally centrally through the disk member and the interior space of the hollow cylinder.

Abstract: A hybrid-power driving system (HPDS) (110) includes an engine, a motor, and a transmission. The HPDS may include a single clutch and the transmission can provide at least six forward speed ratios and can provide for a reverse speed ratio. The transmission can include three synchronizers and multiple gearwheels that are used in multiple speed ratios. In addition to a pure engine driving mode and a pure motor driving mode, the HPDS can operate using a hybrid-power driving mode (HDM). In the HDM, the HPDS can provide for shifting of gears without power interruption to the half-axles and wheels of a vehicle. In the HDM, the continuous power being output can be achieved by keeping a synchronizer engaged to a gearwheel for two consecutive speed ratios.
