摘要： Described herein is a device (1) for synchronization of a reverse gear for a motor-vehicle gearbox (G) comprising:
- a support shaft (2), fixed in rotation;
- an idle gear wheel (4) configured for engagement with a first reverse gear wheel (RG1) on a primary shaft (PS) of a gearbox (G) and with a second reverse gear wheel (RG2) on a secondary shaft (SS) of the gearbox (G), said idle gear wheel (4) being mounted freely rotatable and axially slidable on said support shaft and having a hub including a first friction surface (30); and
- a synchronizer ring (6) mounted mobile on said support shaft (2) along an axial travel (L) and countered axially by means of an elastic element (8) along said axial travel (L), said synchronizer ring having a second friction surface configured for engagement with said first friction surface.
The axial movement of the idle gear wheel (4) towards a position of engagement of the reverse gear causes a drawing of the synchronizer ring (6) that implements, prior to engagement of the reverse gear, a braking of the rotary movement of the idle gear wheel (4).
Moreover described is a corresponding manually operated motor-vehicle gearbox (G).摘要翻译： 在此描述的是一种用于机动车辆变速箱（G）的倒档同步的装置（1），包括： - 固定旋转的支撑轴（2）; - - 空转齿轮（4），所述空转齿轮构造成用于与变速箱（G）的主轴（PS）上的第一倒档齿轮（RG1）和副轴（SS）上的第二倒档齿轮（RG2）接合， ，所述惰轮（4）可自由转动地安装在所述支承轴上并可沿轴向滑动，并具有包括第一摩擦面（30）的轮毂; 以及 - 同步器环（6），其沿着轴向行程（L）可移动地安装在所述支撑轴（2）上并且沿着所述轴向行程（L）借助于弹性元件（8）轴向抵抗，所述同步器环具有第二 摩擦表面被构造成与所述第一摩擦表面接合。 怠速齿轮（4）朝向倒档接合位置的轴向运动引起同步器环（6）的牵引，该同步器环（6）在倒档接合之前执行怠速旋转运动的制动 齿轮（4）。 此外还描述了相应的手动操作的机动车辆变速箱（G）。

摘要： A gear transmission unit, particularly for a motor-vehicle, is provided with a forced lubrication system (3) for lubricating the rolling bearings (B1, B2, B3) and/or further inner components of the transmission unit. The unit is provided with one or more accessory elements in the form of lubricant distribution boxes (S). Each distribution box (S) has a hollow body rigidly connected to the casing (2) of the unit adjacent to a respective channel outlet (5A) which supplies a flow of lubricant under pressure. The hollow body defines an inner lubricant distribution chamber (C) and has an inlet (8) connected to the channel outlet (5A) and two or more outlets (8) connected to further conduits for channels (5B) or chambers, for supplying a flow of lubricant under pressure in parallel to various components to be lubricated inside the transmission casing (2).

摘要： A motor-vehicle transmission with a double clutch coupling device comprises an outer housing (3) and an inner housing (23) defining a closed sealed chamber, within which two clutch couplings (11, 12) are arranged having multiple plates immersed in a cooling lubricant fluid. The transmission comprises a fluid actuator member (18, 20) for each clutch coupling (11, 12). At least one of said fluid actuator members is an annular hydraulic cylinder (20) coaxially mounted around the concentric primary shafts (5, 6) of the transmission. This annular cylinder is supported by an annular flange (22) secured to the main supporting structure (2) of the transmission. The inner housing (23) is carried by said flange (22) which supports the annular hydraulic cylinder (20).

摘要： A gear change device for a motor vehicle includes at least one primary shaft (P) and at least one secondary shaft (S), which have end portions (P1, S1) on the side opposite to the engine that extend beyond respective rolling bearings (C2, C4) and carry at least one gear pair (R51, R52). The end portions (P1, S1) of the primary and secondary shafts (P, S) are configured for being coupled to respective shaft-extension elements (E1, E2), which carry a further gear pair (R61, R62). The shaft-extension elements (E1, E2) are not mounted when it is desired to obtain a gear change device with n gears, whereas they are mounted when it is desired to obtain a gear change device with at least n+1 gears. Interference-fitted on the coupled parts are cylindrical bushings (B1, B2) that ensure coaxiality of the shaft-extension elements (E1, E2) with the primary and secondary shafts (P, S) and consequent proper meshing of the gear pairs (R51, R52; R61, R62) carried thereby.
