20080251343 | Clutch System - The present invention provides a pressure plate for a clutch system that has been modified such that the upper surface provides a plurality of recesses at circumferentially spaced-apart locations, preferably in equally radially spaced locations to form a circular array.

The axial movement permits the bearing to center itself on the shaft during the engagement and disengagement of the clutch disc, thus increasing the pressure capacity of the pressure plate. In this arrangement, the rotational bearing and the pressure plate depressed by the diaphragm when transitioning from a flattened to a curved shape and vice versa.

The apparatus can comprise substantially annular multiple clutch discs connected to an input-side from an engine; substantially annular multiple clutch plates alternately laminated with the clutch discs and connected to an output-side to a wheel; and frictional members secured on surfaces of the clutch discs opposing the clutch plates and adapted to press-contact with or separate from the clutch plates. A power from the engine can be transmitted to the wheel when the clutch discs and plates are press-contacted with each other; the power transmission being blocked by releasing the press-contacting force; wherein depressions are formed on each clutch plate along its periphery and radially inward therefrom; and wherein a part of the one or more frictional members is positioned within a region of the depressions. | 10-15-2015 |
20150345635 | Friction Element Assembly for a Transmission and Method of Assembly - A friction element assembly for a transmission of a motor vehicle includes a set of plates and friction members. A piston assembly is configured to apply a force to the set of plates and friction members. The friction element assembly also includes a housing with a mounting groove; a pressure plate having first and second edges; and a snap ring positioned in the mounting groove. The snap ring is positioned such that first edge of the pressure plate contacts the snap ring and the second edge of the pressure plate extends across a portion of the snap ring. The snap ring is L-shaped and includes a leg portion that contacts the second edge of the pressure plate when the piston assembly applies a force to the set of plates and friction members. | 12-03-2015 |
20150369300 | CLUTCH DISC, CLUTCH ASSEMBLY AND TORQUE TRANSFER DEVICE - A clutch disc for a bracket of a clutch assembly, a clutch, a transmission or a differential of a drive train of a vehicle, with at least two sections, whereby the at least two sections of the clutch disc are arranged in the clutch disc in a radial direction of the clutch disc and are movable relative to one another. A clutch assembly for a clutch, a transmission or a differential of a drive train of a vehicle, with a clutch disc to transmit a torque resulting from an axial force, whereby the clutch disc is configured to be inherently movable in a radial direction of the clutch assembly in such a way, that a radial force can be established in the clutch assembly via the clutch disc, through which the torque is further transmissible. | 12-24-2015 |
20160091030 | Clutch for an Automatic Transmission - A clutch for an automatic transmission for a motor vehicle includes a clutch housing and a retaining ring. In an inner circumferential surface of the clutch housing concentrically at a central axis (M) of the cylinder jacket-shaped inner circumferential surface, a ring groove that is open radially inward is formed, within which the retaining ring is arranged. The retaining ring is thereby open and features two spaced ends. In the area of the ring groove, at least one stop is formed, whereas a distance between the ends from each other or the position of the stop is selected in such a manner that, in the assembled state, only one end of the retaining ring may come into contact with a stop, while the other end is spaced from this stop or an additional stop. | 03-31-2016 |
20160146266 | FLUTTER REDUCING WET CLUTCH FRICTION PLATE - The present invention provides improved clutch plates for use in wet friction pack clutches and brakes which exhibit greatly reduced flutter particularly at high rotational speeds. Friction clutches and brakes include a first plurality of circular clutch plates or discs coupled to a first member comprising a metal core plate having bands of friction material affixed to both faces. These clutch plates are interleaved with a second plurality of circular metal reaction plates which are coupled to a second member. The metal core plate of the first plurality of clutch plates includes a plurality of radial slots spaced about the core plate which extend inwardly a portion of the radial width of the clutch core plate. Different numbers of slots, different spacings and different configurations of slots provide reduced plate flutter with varying thicknesses of core plates and ranges of rotational speeds. | 05-26-2016 |
