摘要： A friction clutch for coupling a drive shaft of a motor vehicle engine to a transmission input shaft of a motor vehicle transmission includes a lamina, an axially movable contact plate, and a plurality of friction disks. The lamina has a first friction surface facing in a first axial direction, and a second friction surface facing in a second axial direction, opposite the first axial direction. The contact plate has a plurality of holders arranged to hold the lamina. Each of the holders forms a positive connection with the lamina in the circumferential direction, and each of the first friction surface and the second friction surface is frictionally connectible to a friction disk to transmit torque. A first friction disk is arranged to be positioned between a counter plate and the lamina, and a second friction disk is positioned between the lamina and the contact plate.

摘要： A clutch plate assembly includes a central axis, a clutch plate with a first friction surface and a radially outer depressed portion, and a friction material ring. The friction material ring is bonded to the first friction surface and extends radially outside of the first friction surface such that an outer portion of the friction material ring is axially aligned with the clutch plate radially outer depressed portion. In an example embodiment, the first friction surface is disposed at an acute angle to a plane orthogonal to the central axis. In some example embodiments, the first friction surface is conical. In an example embodiment, the radially outer depressed portion is conical and axially offset from the first friction surface. In an example embodiment, the radially outer depressed portion is manufactured by machining, stamping, or coining.

摘要： A torsion damper with at least one torque input disk and at least one torque output disk, wherein the torque input disk can move in circumferential direction relative to the torque output disk against the force of at least one spring storage, wherein the relative movement is damped by a friction device which generates a smaller friction torque in a first swivel angle range than in a second swivel angle range in that the friction device has at least two friction ring pairs which are rotatable opposite one another and which are activated depending on the swivel angle via a driving connection of at least one friction ring with the torque input disk. The driving connection has a spring element which is arranged functionally in series with the friction device and functionally in parallel with the spring storage.

摘要： Provided herein is a method for calibrating a clutch by searching for the minimum of a multi-dimensional surface including determining the error between a spline function and recorded data relating to clutch characteristics, creating a multi-dimensional surface corresponding to the error values, determining the minimum of the multi-dimensional surface using the steps of performing a Steepest Gradient & Direction determination step and conducting a Golden Section Search and Switch Direction Step to find a minimum that meets a predetermined closing condition. Additionally, provided herein is a computer-implemented system for calibrating the clutch.

摘要： A clutch apparatus includes a clutch drum and a band. The clutch drum includes spline large-diameter portions protruding outward in a radial direction of the clutch drum and spline small-diameter portions protruding inward in the radial direction. The spline large-diameter portions and the spline small-diameter portions are arranged alternately in a circumferential direction of the clutch drum. The band is wound around an outer peripheral portion of the clutch drum, and is made of carbon fiber reinforced plastic. The spline large-diameter portions are provided with a protrusion protruding outward in the radial direction. The band includes a recessed portion with which the protrusion is engaged. The recessed portion is provided at a position at which the recessed portion faces the protrusion.

摘要： A clutch assembly includes at least a first separator plate and a second separator plate coaxial with and adjacent the first separator plate. The first separator plate includes at least a first magnet arranged such that a first pole of the first magnet faces in a direction toward the second separator plate. The second separator plate includes at least a second magnet arranged such that a first pole of the second magnet having a polarity the same as the first pole of the first magnet faces in a direction toward the first separator plate. The first and second magnets are arranged with respect to each other such that a repulsive force tending to force the first and second separator plates away from each other is generated between like poles of the first magnet and the second magnet.

摘要： A vehicle transmission includes a first rotating element, second rotating element, first retainer ring, and second retainer ring. The first rotating element has an exterior surface that defines a first ring groove. The second rotating element is configured to limit movement of friction plates during clutch engagement. The second rotating element is disposed about the exterior surface and has an interior surface that defines a second ring groove. The first retainer ring is disposed in the first ring groove. The second retainer ring is disposed in the second ring groove and thereby restricts movement of the first retainer ring in a radially outward direction.
