Embodiment Construction

[0025] Referring to FIGS. 1-8C , the dust cover 10 of the present invention is roughly as shown in FIGS. 1 and 2 . The dust cover 10 is a highly resilient device, typically molded into a domed or convoluted shape. The dust cover may take other shapes than domes, including stepped or capped cylinders, accordion folds, or variations of other known shapes. The dust cover 10 is generally made of elastic body such as natural or artificial rubber or various plastics. Choose a material that deforms without appreciable resistance, but whose inherent elasticity tends to return it to its original molded shape after deformation.

[0026] In this embodiment, the body of the dust cover 10 is dome-shaped and includes a large orifice 12 or mounting hole 12 at the housing end 13 having a lip 11 or other suitable for coupling with the joint housing. The structure that the bolt outlet end 19 of 14 tightly fits. The large hole 12 and lip 11 of the dust cover 10 may be reinforced with a rigid ...

Abstract

A dust boot with enhanced protection from contaminants and improved lubrication characteristic includes a dust boot body having a housing opening on one end and on an opposing end a stud opening in an upper boot wall. The boot also includes a wiping lip located on an inner face of the upper boot wall in the stud opening, a grease channel on an outer surface of the upper boot wall bounded circumferentially by a rim seal, an offset opening hole through the upper boot wall into the grease channel which is offset from the wiping lip, and a flexible flap portion of said rim seal which is spaced away from said offset opening hole. The dust boot may also include an insert made from a plastic such as nylon housed in the upper boot wall such that the offset opening hole extends through the insert.

Description

[0001] Related application reference [0002] This patent application claims priority from US Provisional Patent Application Serial No. 60 / 711,366, filed August 25, 2005, which is hereby incorporated by reference in its entirety. field of invention [0003] This invention relates to cap-type seals which, while useful in any device for sealing relative to joints, tiltable or rotatable elements, are particularly suitable for ball-and-socket joints, while automatically relieving or relieving excess pressure-the pressure For example by high pressure lubricating oil or buildup of excess lubricant. Background technique [0004] Almost all original chassis equipment, such as ball joints or tie rod joints, are sealed elements. Since these "lube-for-life" parts are sealed, they are low maintenance, but generally do not last as long as lubricated parts. Lubricable parts may be periodically oiled to replace lubricant that has leaked or stripped during use, thereby removing old lubri...
