    • The present invention relates to a device for a gearbox which comprises a main shaft, a counter shaft, a plurality of gearwheel pairs each comprises a primary gearwheel arranged on the counter shaft and a secondary gearwheel arranged on the main shaft and a PTO shaft. The device comprises a switch mechanism movably arranged to a first position in which the PTO shaft is disconnected from the counter shaft in a non-rotatable state, to a second position in which the PTO shaft is rotationally fixedly connected to the counter shaft, and to a neutral position in which the PTO shaft is in a rotatable state and disconnected from the counter shaft. The device comprises further a clutch mechanism able to provide a clutching connection between the counter shaft and the PTO shaft when the switch mechanism is in the first position and in the neutral position.
    • 本发明涉及一种用于变速箱(2)的装置,其包括主轴(10),副轴(5),多个齿轮对,每个齿轮对包括布置在中间轴上的主齿轮(7-9) 5)以及布置在主轴(10)和PTC(24)轴上的第二齿轮(11-13)。 该装置包括开关机构(40),该开关机构(40)可移动地布置在第一位置和第二位置,在第一位置中,PTO轴以非旋转台状态与中间轴(5)分离,在第二位置中,PTO轴以旋转固定方式连接 到中间轴(5)的中间位置以及PTO轴(24)处于可旋转状态并与中间轴(5)分离的中立位置。 该装置还包括离合器机构(27),当开关机构处于第一位置和中间位置时,该离合器机构能够在中间轴(5)和PTO轴(24)之间提供离合连接。

    • A dual-clutch automatic transmission having seven forward gears and one reverse gear, wherein a seventh-gear driving gearwheel (17), a first-gear driving gearwheel (11), a fifth-gear driving gearwheel (15) and a third-gear driving gearwheel (13) are individually and fixedly arranged on a first input shaft (1), a fourth-gear driving gearwheel (24) and a second-gear driving gearwheel (22) are individually and fixedly arranged on a second input shaft (2), driven gearwheels respectively and correspondingly engaged with the driving gearwheels are rotatably supported on the first output shaft (3) and the second output shaft (4). The fourth-gear driving gearwheel (24) is also used as a sixth-gear driving gearwheel, and the gear sets of other gears are not shared, which is conducive to decrease the overall axial length of the transmission, facilitates full vehicle arrangement, and prevents the speed ratio ranges of other gears from being influenced by sharing of these gear sets to adapt to more vehicle models. In addition, the arrangement of a parking ratchet wheel is optimized in the present invention, the stress distribution on the output shafts can be more even, and thus the stability is improved and the service life is prolonged.
    • 一种具有七个前进档和一个倒档的双离合器自动变速器,其中七档主动齿轮(17),一档主动齿轮(11),五档主动齿轮(15)和三档 (2)分别固定设置在第一输入轴(1)上,第四档主动齿轮(24)和第二档主动齿轮(22)分别固定在第二输入轴(2)上, ),从动齿轮分别对应地与驱动齿轮啮合的齿轮可转动地支承在第一输出轴(3)和第二输出轴(4)上。 第四档主动齿轮(24)也用作六档主动齿轮,其他档位齿轮组不共用,有利于减小变速器的整体轴向长度,便于整车布置,并且 防止其他齿轮的速比范围受到这些齿轮组的共享影响,以适应更多的车型。 另外,本发明优化了驻车棘轮的布置,使输出轴上的应力分布更加均匀,从而提高了稳定性,延长了使用寿命。
