Abstract: A synchronization unit for a positive dual clutch. The synchronization unit has a sleeve carrier that is axially and rotationally fixed to an output shaft and a shifting sleeve that is rotationally fixed and axially displaceable relative to the sleeve carrier. The synchronization rings of a synchronization clutch on the sleeve carrier side and the sleeve carrier comprise axially interlocked circumferential segments.

Abstract: A dual shift coupling including two operatively connected coupling units mounted on a shared, integrally formed inner body in a rotationally fixed and axially movable manner. Further, a multi-part pressure disk is arranged between the coupling units in an axially fixed manner and is supported by the inner body, and has two axially movable pressure pistons ventilated by respective pressure spring assemblies arranged in the inner body. A radial notch for accommodating the pressure disk is provided in the inner body, wherein the radial depth of the notch extends at least to radial inner wall segments of recesses for the pressure spring assemblies. Each pressure spring assembly has a plurality of pressure springs which rest on the inner side of the pressure disk relative to the axis.

Abstract: A brake and clutch unit for mounting on a main shaft of a drive configuration of a cableway, includes a drive section which can be subjected to a drive torque, a hub which can be connected in a rotationally fixed manner to the main shaft and a base section which can be fastened in a positionally fixed manner. A switchable clutch is provided between the drive section and the hub and a switchable brake is provided between the base section and the hub. The switchable clutch is constructed as a friction clutch. A drive configuration for a cableway is also provided.

Abstract: A spring-pressure brake includes a brake housing which has an outside body, and into which are integrated a disk-brake arrangement, an axially movable brake-piston arrangement and a pressure-spring system acting onto the brake-piston arrangement. The outside body is designed as a one-piece hollow body that extends over the entire axial length of the spring-pressure brake and is used for hydraulic disk spring-pressure brakes.

Abstract: Known two-step flexible shaft couplings comprise coupling parts of relatively complex configuration. According to the invention, the coupling elements (7, 7a, 7b) are positively held at least in one circumferential direction, each coupling element comprises an axially open receiving opening that is axially engaged without play by a corresponding jaw of the other coupling part, and the elastic coupling elements comprise at least one cavity for the corresponding jaw, at least on one side of the respective receiving opening—viewed in circumferential direction—, the wall sections of each coupling element adjoining the cavity being elastically deformable.

Abstract: A switch gear with at least two gear stages is provided. At least one gear stage is configured as a switching stage, whereby at least one switching stage is formed by a coaxially nonrotatable sunwheel on a drive shaft, by at least one planet carrier carrying one planet wheel and by at least one ring gear meshing with the planet wheel on the inside, which is held fixed in its housing, and by a cam disk for the actuation of switching elements. The cam disk is provided with a female spline which exhibits approximately the identical pitch circle diameter as the female spline of the ring gear, whereby the female spline of the cam disk exhibits a number of teeth different from the female spline of the ring gear and whereby the cam disk, by means of the female spline, meshes with at least one planet wheel of the switching stage. The switch gear may be used, for example, as a limit switch of cranes.
