The invention relates to a hydraulic transmission device. A continuously variable hydraulic automatic transmission includes an input shaft on which is rigidly mounted a central disc with a radial groove. And two symmetrical pump wheels are mounted on the input shaft on the two sides of the central disc. Radial blades are fixed at the part close to the hub and the periphery of the pump wheel, a row of holes are formed in the space between the radial blades, a shaft is inserted into the holes, and the end part rigidly connected to one of the movable blades is bent along a certain radian. Rotation of the blades in the holes is limited. The end of the blade shaft has a groove on which the blade leg is rigidly fixed perpendicular to the blade shaft. The second end of the blade axis has a protrusion parallel to the blade axis. The two turbine wheels are securely attached with radial blades and covered with a conical or annular disc. And the shell is arranged on a bearing on the driving shaft and in a flywheel shell of the driving device, and is connected with a reversing mechanism and a vehicle chassis. A reduction in weight and dimensional characteristics, an increase in transmission power, an extension in service life, a simplification in design, and improvements in maintainability and operating characteristics of a vehicle automatic transmission are achieved.

    本发明涉及液力传动装置。无级液力自动变速器包含输入轴,其上刚性地安装有带有径向凹槽的中心盘。中心盘两侧的输入轴上安装有两个对称的泵轮。在靠近轮毂的部分和泵轮的外围,固定有径向叶片,在它们之间的空间中有一排孔,轴插入其中,刚性地连接到其中一个活动叶片的端部沿一定的弧度弯曲。叶片在这些孔中的旋转受到限制。叶片轴的端部具有槽,叶片腿垂直于叶片轴刚性地固定在槽上。叶片轴线的第二端具有平行于叶片轴线的突出部。两个涡轮机叶轮牢固地附接有径向叶片,并覆盖有圆锥形或环形圆盘。壳体安装在驱动轴上的轴承上和驱动装置的飞轮壳内,并与倒车机构和车辆底盘连接。实现了重量和尺寸特性的减小、传输功率的增加、使用寿命的延长、设计的简化、车辆自动变速器的可维护性和操作特性的改进。
