A stator assembly for a torque converter includes a body and a washer. The body is rotatable about an axis and has a cavity defined by an axial wall radially spaced from the axis and a radial wall extending radially inward from the axial wall. The washer is disposed in the cavity and is configured to be compressed against the radial wall. The washer includes a base and a plurality of circumferentially spaced from each other and extending radially outward from the base. The plurality of tabs are configured to non-rotatably connect to the axial wall.

A torque converter has a torus. The torus has a size set based on a flatness ratio obtained by dividing a width of the torus in an axial direction by a width of the torus in a radial direction, a thinness ratio obtained by dividing the width of the torus in the axial direction by an outer diameter of the torus, and an inner diameter ratio obtained by dividing an inner diameter of the torus by the outer diameter of the torus.

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 torque converter includes a front cover, an impeller, a turbine, and a stator. The impeller forms a fluid chamber together with the front cover. The stator is disposed between an inner peripheral part of the impeller and an inner peripheral part of the turbine. The stator regulates a flow of a fluid flowing from the turbine to the impeller. A flattening ratio is 0.5 or less. The flattening ratio is herein defined as a first ratio of an axial dimension to a radial dimension of a torus formed by the impeller, the turbine, and the stator. A flow area ratio is 0.14 or greater and 0.16 or less. The flow area ratio is herein defined as a second ratio of a minimum flow area of the impeller and the turbine to an area of an imaginary circle having the outer diameter of the torus as the diameter thereof.

A high-speed hydrodynamic adjustable converter having a working chamber for forming a hydrodynamic working medium circuit wherein a pump wheel, a turbine wheel and a guide wheel are positioned in the working chamber. The working medium flows through the pump wheel centrifugally or centrifugally-diagonally; and the working medium flows through the turbine wheel centripetally or centripetally-diagonally. The inlet grate edge of the turbine wheel, with respect to an axis of rotation of the pump wheel and the turbine wheel, is positioned on a smaller or equal radius than an inlet grate edge of the pump wheel. The hydrodynamic converter has a first guide wheel in the working chamber before the pump wheel viewed in the direction of flow of the working medium, the guide wheel being arranged for purely centrifugal or diagonal-centrifugal throughflow of the working medium and is used to influence the power transmission.

A torque converter stator includes a hub, an outer ring, a plurality of blades, and a plurality of spokes. The hub is disposed about an axis. The blades are disposed radially between the outer ring and the hub. All of the blades are pivotable relative to the hub and outer ring. The spokes are spaced apart from the blades and fixed to the hub and the outer ring to support the outer ring relative to the hub.
