摘要： The invention relates to a friction part (15) for a frictionally working device, having friction lining elements (31-33) which are arranged with slots (34, 35) between one another so as to form a friction surface (16) in the form of a circular disk, which slots can be traversed from radially inside to radially outside, in the radial direction with respect to the friction surface (16), by a coolant and/or lubricant, in which context drag losses arise and air is drawn in with the coolant and/or lubricant.
In order to functionally improve the friction part (16), the conformation of the friction lining elements (31-33) and the arrangement of the friction lining elements (31-33) relative to one another are optimized while taking into account interdependencies between the drawing-in of air and a separation behaviour of the frictionally working device with respect to the drag losses.-

摘要： A method for operating a friction-locking shift element of a transmission of a motor vehicle includes actuating the friction-locking shift element for engagement according to a pressure versus torque characteristic curve. The pressure versus torque characteristic curve has a first characteristic point (a touch point) and a second characteristic point (a contact point), defines a first characteristic curve range between the touch point and the contact point having a first functional dependence, and defines a second characteristic curve range at or after the contact point having a second functional dependence. Once the touch point is reached, the friction-locking shift element begins to transmit torque mainly due to drag torques. Whereas, once the contact point is reached, the friction-locking shift element begins to transmit torque mainly due to friction between shift-element halves of the friction-locking shift element.

摘要： A multi-plate clutch is specified, with an outer plate carrier, an inner plate carrier and a plate pack which consists of alternately arranged outer plates and inner plates and is arranged radially between the outer plate carrier and the inner plate carrier, wherein a first group of the outer plates is mounted on the outer plate carrier and/or a first group of the inner plates is mounted on the inner plate carrier with a larger circumferential backlash than the other outer plates or inner plates, respectively, which are mounted on their plate carrier with no or smaller circumferential backlash, wherein the outer and/or inner plates with larger circumferential backlash in each case directly adjoin at least one plate with no or smaller circumferential backlash. Furthermore, an electrically operated drive train and a method for producing a multi-plate clutch are specified.

摘要： Provided are a wet friction plate and a wet multiplate clutch device including the wet friction plates capable of improving the performance for discharging lubricant oil adhering to surfaces of friction members. A wet friction plate includes oil grooves and friction members on a flat plate annular core metal. At a surface of a porous layer of the friction member, a friction slide surface and lubricant oil recessed portions are formed. The lubricant oil recessed portion has no sharp portion in a pointed shape, such as a corner portion, and is formed with a smooth continuous surface. The multiple lubricant oil recessed portions depressed in a recessed shape with respect to the friction slide surface are formed. In the porous layer, hollow portions are formed to have the same formation rate between a portion forming the friction slide surface and a portion forming the lubricant oil recessed portion.

摘要： A clutch pack for a clutch in a drive train of a motor vehicle includes an axis defining an axial direction and a disk, rotatable about the axis, for contacting a counter-disk to transfer a torque. The disk includes a main body with a contact region for absorbing torque from or transferring a torque to the counter-disk, a toothed region for torque-transmitting contact with a disk carrier, and a region of specific elastic softness in the axial direction disposed between the contact region and the toothed region. In an example embodiment, the region of specific elastic softness in the axial direction is a steel sheet spring region.
