Abstract: A hydrodynamic coupling device is provided including a housing, a lock up clutch, a friction surface mechanism, a fluid duct and three connecting ducts. The lock up clutch has a clutch element arranged in the housing and may be pressed against the housing. The friction surface mechanism is arranged between the clutch element and the housing. The clutch element and the friction surface mechanism separate an interior of the hydrodynamic coupling device into a first fluid space and a second fluid space. The fluid duct means is in the friction surface mechanism and permits the working fluid to flow into and out of the first fluid space while preventing the working fluid from flowing out of the first fluid space into the second fluid space. The connecting ducts are in the fluid duct, with the first connecting duct is capable of permitting flow of the working fluid to the first fluid space, the second connecting duct is capable of permitting flow of the working fluid into and out of the second fluid space. The third connecting duct is capable of circulating the working fluid within the first fluid space before permitting the working fluid to flow out of the first fluid space, at least when the clutch element is pressed up to the housing with the friction surface arrangement interposed between them.

Abstract: A hydrokinetic torque converter is provided with a lockup clutch wherein the piston and other constituents of the lockup clutch are adequately cooled during each stage of operation of the torque converter and its clutch. The piston of the lockup clutch and/or the component which cooperates with the piston to transmit torque from the housing directly to the turbine of the torque converter is provided with a friction lining which establishes a portion of the path for the flow of fluid coolant between the fluid-filled compartments at opposite sides of the piston. The rate of fluid flow between the compartments is regulated by one or more adjustable valves which are carried by the housing of the torque converter and/or by the piston of the lockup clutch.

Abstract: A lock-up clutch-for a hydrodynamic torque converter has a piston connectable to a converter housing through at least one friction lining and the piston is capable of a deflection movement in the axial direction. In the friction lining and in one of the piston or the converter housing, at least one depression is embodied for the passage of hydraulic fluid from the converter circuit. Associated with at least one of these depressions is an inflow and outflow, the former opening radially outside into the converter circuit and the latter opening radially inside into a chamber between the converter housing and the piston. The inflow depression and the outflow depression are both provided in one converter components, while a passageway depression is active in the adjacent converter component. The inflow or outflow depression runs, starting from the outer or inner circumference of the friction lining, at least into the extension area of the passageway depression, so that at least one fluid connection is established between the inflow and outflow depression and a passageway depression.

Abstract: A lockup clutch for a torque converter (10) has a piston (63) with a tapered face (67) that engages a grooved friction material (61). The edge (71) of the piston face (67) extends outward away from the center portion (69) of the piston face (67) toward the friction material (61). The friction material (61) is arranged in a pattern of concentric lands (80, 82, 84) defining annular grooves (86) between adjacent lands with an innermost land (82) being free of radial grooves (92) and all other lands being connected by radial grooves (92) in communication with the interior of the torque converter housing (12, 14) through the torus circuit cavity. The innermost land (82) blocks fluid flow from the torus flow circuit cavity when the piston (63) engages the disk (61) in a hard lockup condition but permits fluid flow during a soft lockup condition.

Abstract: A lock-up clutch for a hydrodynamic torque converter which includes at least one piston which can be displaced in the axial direction and can be connected to the converter housing by means of at least one friction zone, which piston defines, by means of the side which faces the converter housing, a chamber in which, when the lock-up clutch is active, the pressure is lower than the pressure in the converter circuit, and which, in the vicinity of a friction zone, has at least one channel for the flow of hydraulic fluid from the converter circuit. The quantitative flow of hydraulic fluid is a function of the pressure exerted by the converter. The lock-up clutch further includes at least one friction zone which has at least one friction lining, whereby the lock-up clutch has a total of at least two friction linings of different axial dimensions which, in the event of different pressures acting in the converter, come into at least partial effective connection with the matching friction surfaces.

Abstract: The present invention provides a lock-up clutch for a torque converter. The lock-up clutch includes an outer carrier, an inner carrier, a first friction plate, a rotation of which is restricted by the outer carrier, and a second friction plate, a rotation of which is restricted by the inner carrier. All key grooves of the outer and inner carriers are opened in two radial opposite directions, and flow path grooves defined between friction members attached to the friction plate are aligned with circumferential positions of keys of the friction plate. Therefore, oil for cooling a clutch pack may smoothly flow through the inner carrier, the flow path grooves, and the outer carrier.
