    • The invention relates to a central shaft (7) with desmodromic channels, coaxial and internal to a driven shaft (1), slidable in the two directions and exhibiting a plurality of longitudinal grooves (8) inside which, for every second cogged wheel (2) a corresponding plurality of heads (9a) of pivots (9) are housed and blocked, which pivot heads (9a) are destined to exit, with their free end and on a longitudinal sliding action of the said central shaft (7), from corresponding radial seats (10) realised on the said driven shaft (1); to key each single cogged wheel (2) to the said driven shaft (1), locking means (11) are envisaged in rotation, arranged on each second cogged wheel (2) and acting on each pivots (9) which exits.

    • A transaxle having five forward speeds and reverse includes a shift shaft (44) on which are journalled for free rotation four forward speed change gears (58-64) and an input bevel gear (72) which is integrally conjoined with a first speed change gear (66). A reverse gear (68) is also journalled for free rotation on the shift shaft and a neutral spacer (132) is disposed between reverse gear and the four forward gears. A counter shaft (46) carries five companion spur gears (48-56) in constant running mesh with the forward speed change gears. One of the companion gears (48) is also in constant running mesh with a reverse intermediate gear (70) which is in constant running mesh with the reverse gear. The reverse intermediate gear is supported by a half-bearing (132) in the transaxle housing. A pair of axially slidable and radially outward biased shift keys (78, 80) on the shift shaft selectively couple the forward speed change gears, the input bevel gear, and the reverse gear to the shift shaft. High gear is provided by coupling the bevel gear directly to the shift shaft and bypassing the counter shaft. A differential (112) driven by a spur gear on the shift shaft drives the output drive shafts of the transaxle.
    • 具有五个前进速度和反向转速的变速驱动桥包括一个换档轴(44),其上安装有用于自由旋转的四个前进变速齿轮(58-64)和一个输入锥齿轮(72),其与第一变速齿轮 (66)。 倒档齿轮(68)也被轴颈安装在换档轴上自由旋转,并且中间间隔件(132)设置在倒档齿轮和四个前进档之间。 副轴(46)带有与前进变速齿轮恒定运行的五个配对正齿轮(48-56)。 伴随齿轮(48)中的一个也处于与逆向齿轮恒定运行的反向中间齿轮(70)的不断运行的网格中。 反向中间齿轮由变速驱动桥壳体中的半轴承(132)支撑。 换档轴上的一对可轴向滑动和径向向外偏置的换档键(78,80)选择性地将前进变速齿轮,输入锥齿轮和倒车齿轮联接到换档轴。 通过将锥齿轮直接连接到换档轴并绕过副轴来提供高齿轮。 由换档轴上的正齿轮驱动的差速器(112)驱动变速驱动桥的输出驱动轴。
