摘要： A multi-plate clutch includes a plate fin and first and second flanges connected to one another in a torque-transmitting manner via the plate fin. A screw fastener braces the plate fin on a first lamellar bore with the first flange, and a first spacer element is arranged on the plate fin to support a first axial movement of the second flange.

摘要： A friction clutch assembly for an automatic transmission is provided. The friction clutch assembly is configured to move between an applied position and a released or disengaged position. A plurality of clutch plates may include friction plates and interleaved reaction plates, plus an apply plate and a backing plate. A separator feature is disposed adjacent to at least one of the reaction plates, the friction plates, the apply plate, and the backing plate. At least one of the reaction plates, the friction plates, the apply plate, and the backing plate defines a passage configured to allow fluid to flow through the friction clutch assembly and around the separator feature.

摘要： A clutch actuation device selectively engages a clutch. The clutch actuation device includes two plates, at least one of which being able to rotate relative to the other. Between the two plates is a rounded member, such as a ball, housed within opposing grooves in the respective plates. As the plates rotate relative to one another, the rounded member forces the plates to separate axially from one another. This can engage the clutch. A third plate is placed at a location axially spaced from the second plate. The third plate limits movement of the second plate when moving to the extended position, assuring the second plate does not over-translate axially. A resilient member may be provided between the third plate and a housing. The resilient member can be tuned to properly inhibit the axial movement of the second and third plates according to the packaging constraints.

摘要： A friction clutch having at least one clutch part (1; 31) which has at least one friction lining (3; 33) with a friction surface (10; 40) which, when the friction clutch is closed, is connected in frictionally engaging fashion to a counterpart clutch part, wherein the friction lining (3; 33) and/or a carrier element (6) of the friction lining (3; 33) is, in a circumferential direction, of undulating shape with wave troughs (20) and wave crests (18, 19), wherein, when the friction clutch is open, the friction lining (3; 33) comes into contact with the counterpart clutch part not with the entire friction surface (10; 40) but only substantially in punctiform fashion in the area of peaks (15-17) of the wave crests (18, 19). The friction lining (3; 33) has reduced friction values locally in the region of the peaks (15-17) of the wave crests (18, 19) in relation to the friction surface (10; 40) surrounding the peaks (15-17) of the wave crests (18, 19).

摘要： A transmission is provided. The transmission may include a planetary gearset. The transmission may also include a thrust hub that may be fixed to the planetary gearset and engaged with a thrust bearing. A clutch hub may be connected with and spaced away from the thrust hub such that the thrust and clutch hubs are not in contact with each other to reduce vibration transfer between the thrust and clutch hubs.

摘要： An elastic return device including a gasket and a clutch mechanism whose actuating system includes a control chamber designed to receive a pressurized fluid, a piston which is axially movable in the control chamber so as to engage or disengage the corresponding clutch, a balancing chamber situated opposite the control chamber in relation to the piston, and an elastic return device housed in the balancing chamber and designed to exert an axial force against the piston. According to the invention, the elastic return device includes, on one of its faces bearing against the piston, an internal peripheral end which extends radially beneath the piston and which carries a gasket in order to seal off the balancing chamber from the control chamber. The invention likewise relates to a transmission system including such a dual clutch mechanism.

摘要： The lubricating structure includes a rotary shaft, a power transmission apparatus having a power transmission element disposed on an outer circumference of the rotary shaft and formed by alternately stacking frictional members, and a flow channel guides a lubricating liquid to the power transmission element. The power transmission element includes an inner circumferential cylindrical section rotated integrally with the rotary shaft, an outer circumferential cylindrical section rotated integrally with the frictional member, and a disk section configured to connect the inner circumferential cylindrical section and the outer circumferential cylindrical section. Inner-diameter-side through-holes through which a lubricating liquid passes on an inner diameter side of the disk section and outer-diameter-side through-holes through which a lubricating liquid passes on an outer diameter side of the disk section are formed in the disk section, and the inner-diameter-side through-holes and the outer-diameter-side through-holes are alternately disposed in a circumferential direction of the disk section.

摘要： A motor vehicle clutch assembly is provided. The motor vehicle clutch assembly includes a radially extending section including an abutment surface; a clutch pack including a first clutch plate and a separator plate; an axially movable piston for engaging the clutch pack; and elastic connectors connecting the separator plate to the radially extending section. The elastic connectors preload the separator plate away from the abutment surface. The motor vehicle clutch assembly also includes a stop arranged for contacting the separator plate to limit axial movement of the separator plate away from the abutment surface. The stop is an axial distance away from the abutment surface such that the separator plate is forceable by the elastic connectors against the stop to provide clearance such that the first clutch plate is movable away from the abutment surface. A method of forming a motor vehicle clutch assembly is also provided.
