摘要： According to one embodiment, a transmission includes a first shaft, a first gear pair, a second gear pair, a synchronization mechanism, and a clutch mechanism. A first sleeve of the synchronization mechanism is movable along the axis of the first shaft between a pressing position, in which the first sleeve presses a second cone surface of a synchronizer ring against a first cone surface of a third gear of the second gear pair, and a non-pressing position in which the first sleeve does not press the second cone surface against the first cone surface. The clutch mechanism transmits rotation between the first shaft and a first gear of the first gear pair and transmits no rotation between the first shaft and the third gear. The clutch mechanism transmits rotation between the first shaft and the first gear while the first sleeve moves from the non-pressing position to the pressing position.

摘要： A power transmission control apparatus for a vehicle c has a plurality of fork shafts coupled with “sleeves engageable with free-rotating gears”, including first and second fork shafts. When both the first and second fork shafts are in neutral positions, the first and second fork shafts are not coupled in the axial direction so that, while one fork shaft is maintained in its neutral position, the other fork shaft is movable by an actuator from its neutral position to its meshing position. When the one fork shaft is in its neutral position and the other fork shaft is in its meshing position, the first and second fork shafts are coupled in the axial direction so that, when the one fork shaft is moved from its neutral position to its meshing position by the actuator, the other fork shaft is simultaneously moved from its meshing position to its neutral position.

摘要： Two of “shared drive gears”, which are “a drive gear G23i used as second-gear drive gear and third-gear drive gear in common” and “a drive gear G57i used as fifth-gear drive gear and seventh-gear drive gear in common”, are arranged to the input shaft A1. The teeth number of second final drive gear Gfi2 is larger than the teeth number of first final drive gear Gfi1. Gfi1, a first-gear driven gear G1o, a second-gear driven gear G2o, a reverse-gear drive gear rotates unitarily with a second-gear driven gear G2o, a sixth-gear driven gear G6o and a fifth-gear driven gear are arranged to the first intermediate shaft A2, and Gfi2, a fourth-gear driven gear G4o, a third-gear driven gear G3o, a reverse-gear driven gear GRo and a seventh-gear driven gear are arranged to the second intermediate shaft A3 in order from the one side of axial direction.

摘要： In this power transmission control device, an EV travel mode for traveling by using only an electric-motor driving torque in a state in which a clutch torque is maintained to zero, and an EG travel mode for traveling by using the internal-combustion-engine driving torque in a state in which the clutch torque is adjusted to a value larger than zero are selectively realized depending on a travel state. In a state in which the EV travel mode is selected, when it is determined that a vehicle speed is higher than a predetermined speed Vth, “a gear position to be realized” is changed depending on the travel state of the vehicle, and when it is determined that the vehicle speed is equal to or lower than the predetermined speed Vth, “the gear position to be realized” is maintained to a current gear position independently of the travel state of the vehicle.

摘要： A dog clutch includes a gear (40) mounted on a power transmission shaft (30), first and second dog rings (10, 20), a fork (60), springs (65), and cam grooves (31). The cam grooves (31) each include a first slope surface (36) inclined from the axial direction toward the positive rotation direction as the first slope surface (36) approaches the gear (40) and a second parallel surface (37) parallel to the axial direction. The first dog ring (10) includes first cam protrusions (16) to be engaged with the respective first slope surfaces (36), and the second dog ring (20) includes second cam protrusions (26) to be engaged with the respective second parallel surfaces (37). This structure prevents the dog rings and the fork from coming into contact with each other, thereby avoiding generation of abrasion and increasing the transmission efficiency.
