A hydraulic torque converter comprises a housing (G), in which two vane cell stator/rotor sets (SR1, SR2) are arranged one behind the other. The two sets are in hydraulically communicating connection with one another. The rotors (6, 6′) are connected to a driveshaft (P) or an output shaft (M). The stators (7, 7′) are at a spacing from the associated rotors (6, 6′), and the spacing can be varied in at least one radial direction on the basis of pressure and/or centrifugal force, wherein means (75, 76, 77) are present in order to regulate the spacing from the associated rotor (6, 6′). This enables an inexpensive production of a continuously variable transmission which is, in addition, easy to regulate and has an optimized transmission of force.

A centrifugal pendulum absorber for a torque converter is provided. The centrifugal pendulum absorber includes a center plate; a roller received in a roller slot formed in the center plate; and a first mass on a rear axial side of the center plate and a second mass on a front axial side of the center plate. The first and second masses are slidable with respect to the center plate along the slot roller. The first mass includes a first radially extending section and a first axial protrusion extending axially past a rear-side axial surface of the first radially extending section. The second mass includes a second radially extending section and a second axial protrusion extending axially past a front-side axial surface of the second radially extending section. A torque converter and a method of forming a centrifugal pendulum absorber are also provided.

A continuously variable transmission, provided with an outer housing (1), wherein an intermediate housing (101) is arranged in the middle of the outer housing, and a first end cover (102) and a second end cover (103) are arranged on the two sides of the intermediate housing; a first shaft (3) with a hollow interior is arranged in the middle of the first end cover in a penetrating mode, a first sun gear (401) is fixedly arranged on the first shaft, and a first planetary gear set (4) is formed by a first planetary gear (402) and the first sun gear; a second shaft (6) is arranged in the middle of the second end cover in a penetrating mode, a second sun gear (701) is fixedly arranged on the second shaft, and a second planetary gear set (7) is formed by a second planetary gear (702) and the second sun gear; a bucket wheel planetary gear set (10) is formed between the first planetary gear set and the second planetary gear set; and a third shaft (15) is fixedly arranged in the middle of a bucket wheel sun gear (1001) and penetrates a first supporting frame (5) and the first shaft. The described continuously variable transmission solves the technical problem of, when a bucket wheel of a continuously variable transmission rotates, the bucket wheel allocates the input torque or increases the resistance torque, and the bucket wheel cannot be controlled by means of the external force. The described continuously variable transmission may be widely used in the field of transmission.

The invention relates to a hydrodynamic transmission gear-box that contains two pump wheels, which are round flat disks, on the front peripheral part of which installed firmly are radially directed blades. The first wheel is rigidly connected to the input shaft. The second and subsequent pump wheels, each with a diameter greater than the previous one, are mounted with their own hubs onto the hubs of the preceding pump wheels with the possibility of free rotation on them. On the back side of each disk, a device is installed to block it with the next pump wheel, and the last pump wheel—with the turbine wheel. The turbine wheel is mounted on the input shaft and in the crankcase of the drive device on bearings and is connected to vehicle's reverse mechanism and running gear. Reduction in weight and size, increase of service life and performance improvement are achieved.

A protection device for a drivetrain of a motor vehicle having an engine and an automatic transmission, with at least one hydraulic converter. In order to protect the drivetrain, the protection device has a sensor device and a control device. The sensor device is designed to detect a rolling movement of the motor vehicle counter to the selected direction of travel of an engaged gearspeed of the automatic transmission, and the control device is designed to control a brake system of the motor vehicle as a function of the detected rolling movement, in order to limit a rolling speed of the motor vehicle counter to the selected direction of travel to a maximum speed.
