摘要:
Provided is a power transmission control apparatus for a vehicular which controls shift operation of a transmission among gear stages through use of actuators and which can shorten the neutral period in the shift operation and can perform skip shift. A plurality of fork shafts coupled with "sleeves engageable with free-rotating gears" include first and second fork shafts. When both the first and second fork shafts are located in their 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 can be moved by an actuator from its neutral position to its meshing position. When the one fork shaft is located in its neutral position and the other fork shaft is located 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.

A drive member selection mechanism is described, comprising at least one drive member and at least two selector members, wherein the drive member comprises a first and second face, and further comprises, on each face, at least one projection, and the selector members comprise, on at least one face thereof, at least one complementary projection arranged to selectively engage with a projection of a drive member, the arrangement being such that the projection(s) of a selector member and the projection(s) of the first face of a drive member may be drivingly engaged in a first torque connection and the projection(s) of a selector member and the projection(s) of the second face of a drive member may be drivingly engaged in a second torque connection, wherein the second torque connection is opposed to the first torque connection.

A synchromesh automatic transmission (200) includes a lug lock portion (88a to 88c) which is engaged with a shift lug (65a to 65d) separately from a shift finger (70a to 70c) and enables a shift fork (64a to 64d) to be controlled so as to be located at a neutral position, a shift selector mechanism (67) which achieves a target shift stage by engaging the shift finger (70a to 70c) with the shift lug (65a to 65d) of the shift fork (64a to 64d) corresponding to the target shift stage and displacing this shift fork (64a to 64d) in a shift direction, and an interlock mechanism (80) which controls a shift fork (64a to 64d) that is different from the target shift stage so as to be located at a neutral position by displacing the lug lock portion (88a to 88c) following movement of the shift finger (70a to 70c) in a selection direction and engaging this lug lock portion (88a to 88c) with the shift lug (65a to 65d) of the shift fork (64a to 64d) that is different from the target shift stage.
摘要:
Es wird vorgeschlagen eine Schalteinrichtung (10) für ein automatisiertes Stufengetriebe, das wenigstens sechs Gangstufen (1-7) aufweist, insbesondere ein Kraftfahrzeuggetriebe, mit wenigstens zwei Schaltwellen (12a, 12b), denen jeweils drei oder vier der Gangstufen zugeordnet sind, wobei die Schaltwellen (12a, 12b) ferner jeweils, nach der Art eines H-Schemas, in einer Schaltrichtung (16) zum Schalten von zugeordneten Gangstufen und in einer Wählrichtung (18) zum Auswählen von zugeordneten Gangstufen bewegbar sind, wobei wenigstens einer der Schaltwellen (12a, 12b) eine mechanische Verriegelungseinrichtung (50a, 50b) zugeordnet ist, die die Gangstufen, die dieser Schaltwelle zugeordnet sind, gegeneinander verriegelt.
