A seal device for use in sealing between parts of a thrust assembly of a disc brake has a support element (31) adapted to be carried by a first part (25) of the thrust assembly, the support element (31) carrying a seal (33) arranged so that, with the support element (31) in its position of use on the first part (25), the seal (33) engages a surface of a second part (25) of the thrust assembly in sealing relationship. Also disclosed is a thrust assembly for a disc brake and a disc brake incorporating such an assembly.

A slip joint includes first and second shafts that are connected for concurrent rotational movement and for relative axial movement, such as by respective pluralities of axially extending spline. A seal can is secured to the first shaft and extends about a portion of the second shaft. A seal assembly is secured to the second shaft and engages a portion of the seal can. The seal assembly includes first and second seals that are each generally concave in shape. Each of the first and second seals is generally V-shaped in cross section, having a radially innermost end, an intermediate portion, and a radially outermost end, wherein the radially innermost and outermost ends are located closer to one another than the radially intermediate portions. the first and second seals are axially spaced apart from one another so as to define an annular space therebetween that can be filled with a sealing material, such as a waterproof grease. The first and second seals can be secured to a backing member that is secured to the second shaft.

A washer seal for a cam braking system is disclosed that sealingly abuts a bushing assembly and a camshaft. The washer seal is preferably made of a metal washer bonded to a flexible material. The bushing assembly supports the camshaft in the cam braking system. The bushing washer seal is preferably generally ring-shaped having a first ring-shaped flat section defining a bore along a longitudinal axis, a second ring-shaped curved section contiguous with and spaced radially from the first section, and a lip that extends longitudinally from the second section. In a preferred embodiment, the lip extends from the washer seal at an angle from the washer seal second section. In an alternative embodiment, the lip extends from the washer seal at an angle from the washer seal first section. The bushing assembly includes a radially outer surface. The lip of the washer seal deforms radially outwardly to engage the bushing assembly radially outer surface, thereby providing an axial locating feature. The lip remains radially outwardly expanded while engaged with the bushing assembly. The internal bore of the washer seal is angled to receive the camshaft. Preferably, the washer seal does not rotate with the camshaft. Alternatively, the washer seal does rotate with the camshaft.

A sealing assembly for a slip shaft drive assembly includes a generally resilient seal and a substantially rigid cover which is mounted at an end of a slip yoke. The cover includes an axially extended stop portion which is of an axial length to provide contact with a flange of a splined shaft prior to an end of the splined shaft contacting a plug. The stop portion defines the minimum length to which the slip shaft drive assembly may be collapsed and thereby eliminates the possibility of the plug being dislodged during shipping and/or handling.

A grease seal cup for a splined joint between a drive shaft and a driven shaft comprises a cylindrical portion adapted to form a seal with the outer surface of the drive shaft and a seal with a sealing member, such as a spanner nut, of the driven shaft. The grease seal cup, comprising a flexible polymer material, tightly squeezed during installation to form the seals. The pre-fabricated light weight grease seal cup can be used in existing splined joints without adversely affecting the weight balance.
