    • A change gear transmission of the group design, especially for vehicles for agriculture and construction with a group transmission following a velocity control transmission the output shaft of which is arranged parallel to a main shaft. This main shaft is provided with gears connected to the main shaft for rotation therewith. The main shaft is driven through the intervention of a counter shaft of the velocity control transmission, which counter shaft is parallel to the main shaft. The counter shaft is through an input transmission continuously frictionally connected to the input shaft which latter is adapted by a clutch element in a direct velocity stage to be coupled to said main shaft. All gears of the main shaft mesh directly or indirectly with gears freely rotatable on said counter shaft and output shaft respectively. Each pair of these freely rotatable gears have associated therewith a common double control member which is axially displaceable on and connected to the output shaft and counter shaft respectively. One of the gears connected to the main shaft for rotation therewith meshes with a reversing transmission which latter includes a gear that meshes with one of the gears which are freely rotatable on and can selectively be coupled to said output shaft.

    • The invention relates to a gearbox switchable under load, which has an input shaft coupled to at least one further shaft, which extends parallel to the input shaft, via pairs of gearwheels to achieve different gear stages. One gearwheel of each pair of gearwheels is rotatively fixedly connected to one of the two shafts and the other gearwheel of each pair of gearwheels is optionally rotatively fixedly connectable to the other of the two shafts by a respective friction coupling. Also, in the gearbox, the input shaft is rotatively fixedly connected to an engine shaft; mechanism to reverse the direction of rotation is provided in the torque flow from the input shaft to the output pinion; and mechanism for approximately simultaneously loading the friction couplings of the two lowest gear stages is provided and for starting purposes when driving forward and reversing, the torque flow through both friction couplings is maintained, at most, until an identical speed has been reached between the elements of the friction coupling of the lowest gear stage.
    • 本发明涉及一种能够在负载下切换的齿轮箱,其具有通过成对的齿轮将平行于输入轴平行延伸的至少一个另外的轴连接的输入轴,以实现不同的齿轮级。 每对齿轮的一个齿轮可旋转地固定地连接到两个轴中的一个,并且每对齿轮的另一个齿轮可选地通过相应的摩擦联接器可旋转地固定地连接到两个轴中的另一个。 此外,在齿轮箱中,输入轴可旋转地固定地连接到发动机轴上; 在从输入轴到输出小齿轮的扭矩流中提供反转旋转方向的机构; 并且提供了用于大致同时加载两个最低档位的摩擦联接器的机构,并且为了在向前和向后推动时的起始目的,通过两个摩擦联接器的扭矩流最多被维持直到在元件之间达到相同的速度 的最低档位的摩擦联轴器。
