    摘要: The present invention relates to an arrangement and a method for engagement of a gear in a gearbox. The arrangement is adapted, in connection with disengagement of a gear that is defined by a first secondary cogwheel (7c), and an engagement of a gear that is defined by a second secondary cogwheel (7b), to provide an activation movement of the synchronising device (10b) for the second secondary cogwheel (7b), from a disconnected state to a synchronisation state, and subsequently to a locked state. The arrangement (13) is adapted (7a-d) to also provide an activation movement, during the engagement of said gearing, of at least one extra synchronising device (10a) for a third secondary cogwheel (7a), and to set the extra synchronising device (10a) in the synchronisation state during at least a part of the time when the synchronising device (10b) for the second secondary cogwheel (7b) is in the synchronisation state, so that the extra synchronising device (10a) also participates in the synchronisation of the second secondary cogwheel's (7b) rotational speed with the main shaft (8).

    摘要: The present invention is directed toward a shift actuator assembly (50) that includes a housing (70) having a retaining mechanism (90). A holding pawl (94) is biased into engagement with the retaining mechanism. A solenoid (112) releasably engages the pawl when the shift shaft (52) is disposed in its first position such that once the solenoid disengages the pawl, the cam surfaces (92) on the retaining mechanism cooperate with the holding surfaces (96) on the pawl to drive the pawl out of engagement with the retaining mechanism thereby releasing the biasing force of the biasing mechanism (76) to drive the housing and the shift fork (72) axially on the shift shaft between engaged and disengaged positions with respect to the associated gear set.

    摘要: Described herein is a gearbox (1) for a motor vehicle including a plurality of forward gear ratios (I, II, III, IV, V, VI) and a reverse gear ratio (RM), the gearbox (1) further including:
    - a control device (106) configured for controlling the selection and the engagement of said forward gear ratios (I, II, III, IV, V, VI) and of said reverse gear ratio (RM); and
    - a plurality of engagement devices (S1/2, S3/4, S5/6 SRM) that can be controlled by means of said control device (106) for engaging the forward gear ratios (I, II, III, IV, V, VI) or reverse gear ratio (RM) of the gearbox (1) that are operatively associated to said devices.
    The gearbox (1) includes a locking device (170), which is electrically controlled and configured for preventing actuation of the engagement device (S1/2) associated to a predetermined forward gear ratio (I, II), said locking device (170) being configured for being actuated above a threshold speed of the motor vehicle on which said gearbox (1) is installed.
