A sealing element for sealing a joint chamber of a constant velocity joint is disclosed. The sealing element comprises an inner collar for providing a sealing connection relative to an inner joint part of the constant velocity joint, an outer collar for providing a sealing connection relative to an outer joint part of the constant velocity joint, and a membrane portion which extends between the inner collar and the outer collar. The membrane portion between the inner collar and the outer collar is fold-free and substantially conical in shape. A joint assembly having a constant velocity joint and a sealing element is also disclosed.

Sealing element for a constant velocity joint and constant velocity joint assembly

The invention relates to a connecting assembly which is used, more particularly for use in the driveline of a motor vehicle. The connecting assembly comprises a shaft journalwith an outer journal groove; a constant velocity universal jointwith an inner joint partwhich, for the purpose of transmitting torque, is connected to the shaft journalin a rotationally fixed way, wherein the inner joint partcomprises a sleeve-like portionwith an inner annular groove; a radially elastically widenable axial securing ringwhich is provided for axially fixing the inner joint partand which is positioned in the journal grooveof the shaft journal; and securing meanswhich are fixed to the sleeve-like portionand prevent the axial securing ringfrom being radially widened.

A wheel hub/universal joint assembly having an axis of rotation A constant velocity universal joint with an outer joint part, an inner joint part, and torque transmitting balls The outer joint part has a first face toothing which engages a second face toothing provided at a collar on a sleeve portion of the wheel. Clamping means axially clamps the wheel hub to the outer joint part. The clamping means is axially supported on the wheel hub and the outer joint part The ratio of the axial length Bof the wheel bearingand the mean diameter Dof the face toothing is smaller than 0.63, i.e. B/D&#x3c;0.63.

A sealed joint assembly includes an outer joint part () with outer ball tracks (), an inner joint part () with inner ball tracks (), torque transmitting balls () which are guided in pairs of tracks and held in a cage () with cage windows (). A sleeve () is connected to the inner joint part () and is coaxially arranged thereto. A sealing mechanism () with an annular cap () is fixed to the outer joint part () and includes a sealing diaphragm () with an outer collar () connected to the annular cap () and an inner collar () sealingly connected to the sleeve (). A securing ring () fixes the inner collar () on the sleeve (). The sleeve () has an annular groove () which is engaged by the sealing diaphragm () by an inner annular bead () formed on the inner collar ().

The invention relates to a rolling boot () and to a rolling boot assembly including such a rolling boot and two attaching parts. The rolling boot () comprises a first axially flexible portion () having a first radially outer collar (), a second axially flexible portion () having a second radially outer collar (), and an approximately cylindrical connecting portion () which adjoins the two portions () on the radial inside. The rolling boot assembly is provided with a first attaching part () comprising a fixing portion () which opens towards the second portion and which, from the outside, continuously approaches the first portion () of the rolling boot () in the direction of the first collar (), as well with a second attaching part () comprising a fixing portion () which opens towards the first portion () and which approaches the second portion () in the direction of the second collar ().

Rolling boot and rolling boot assembly

An axial plunging unit for transmitting torque within a driveline, includes a profiled sleeve ( ) with circumferentially distributed longitudinally extending first ball grooves ( ), a profiled journal ( ) with circumferentially distributed longitudinally extending second ball grooves ( ), and balls ( ) which are arranged in pairs of first and second ball grooves ( ) in groups (k) of balls, wherein the number of first ball grooves ( ) corresponds to m times the number k of the groups of balls and wherein the longitudinal axes of the first, second, etc. to the m of the first ball grooves , as counted circumferentially, are positioned on different pitch circle diameters.
