    • The invention concerns a gearbox (10) comprising at least a shift torque shaft (18) bearing a first stationary reverse gear (42) with straight bevel and a fourth stationary forward gear (28), and a transmission main shaft (22) bearing a second stationary reverse gear (46) with straight bevel and a third forward idler gear (30) adapted to be synchronised by an axial synchromesh (34) then interlocked on the transmission main shaft (22), and wherein a countershaft (45) bearing a stationary reverse idler gear (44) with straight bevel slides axially to mesh the idler gear (44) with the first (42) and second (46) gears. The invention is characterised in that it comprises controlled means to brake the shift torque shaft (18) with the forward gear synchromesh (34), to synchronise the speeds of the stationary reverse and forward gears (42, 44, 46) before they are mutually meshed. The invention is applicable to a robot control gearbox.
    • 本发明涉及一种齿轮箱(10),其包括至少一个带有直斜角的第一固定倒档(42)和第四固定前进齿轮(28)的换档扭矩轴(18)和传动主轴(22) 具有直斜面的第二固定倒档齿轮(46)和适于通过轴向同步啮合(34)同步的第三前进惰轮(30),然后在变速器主轴(22)上互锁,并且其中轴 具有直斜面的固定倒档惰轮(44)轴向地滑动以使惰轮(44)与第一(42)和第二(46)齿轮啮合。 本发明的特征在于它包括用前进齿轮同步啮合(34)制动换档扭矩轴(18)的控制装置,以使它们相互间的固定倒档和前进档(42,44,46)的速度同步 啮合。 本发明适用于机器人控制齿轮箱。

    • An indexing and braking mechanism for a manual transmission having a shifting mechanism and at least one rotatable drive shaft is disclosed. The mechanism includes an indexing mechanism for controlling movement of the shifting mechanism between at least a first position and a neutral position. The indexing mechanism has a plate having a plurality of notches formed thereon, wherein one notch corresponds to the first position and another notch corresponds to the neutral position. A locking mechanism is provided for selectively limiting movement of one of the at least one rotatable drive shaft. The locking mechanism is adapted to selectively engage the plurality of notches to selectively maintain the indexing mechanism in one of the first position and the neutral position. The locking mechanism includes an indexing lever having a contact surface for contacting the rotatable drive shaft.
    • 公开了一种具有变速机构和至少一个可旋转驱动轴的手动变速器的分度和制动机构。 该机构包括用于控制移动机构在至少第一位置和中立位置之间的运动的分度机构。 分度机构具有形成有多个切口的板,其中一个切口对应于第一位置,另一个切口对应于中立位置。 提供锁定机构,用于选择性地限制所述至少一个可旋转驱动轴中的一个的运动。 锁定机构适于选择性地接合多个凹口以选择性地将分度机构保持在第一位置和中立位置之一中。 锁定机构包括具有用于接触可旋转驱动轴的接触表面的分度杆。
