A constant velocity joint boot assembly includes a boot that may be positioned around a constant velocity joint on a vehicle. The boot has a longitudinal cut. Thus, the boot may be selectively placed around the constant velocity joint when the constant velocity joint is mounted to the vehicle. A zipper is coupled to the boot. The zipper closes the boot around the constant velocity joint. The zipper extends beyond the first end of the boot and the second end of the boot to define a pair of free ends of the zipper. Each of the free ends of the zipper is rolled up when the zipper is closed. Thus, the zipper may resist being contaminated thereby enhancing functionally of the zipper over time.

A protective device for a universal shaft (3) has an attachment element (6), a tubular guard (7) and at least one latching device (24, 25). The attachment element (6) is positioned around a shaft journal (2) projecting from a housing (1). The tubular protective protective guard (7) extends along a longitudinal axis L and is positioned around a universal shaft (3) connected to the shaft journal (2). The at least one latching device (24, 25) attaches the protective guard (7) on the attachment element (6). The protective guard (7) has at least one joining lines (9, 10) extending in the longitudinal direction L. The protective guard (7) can be separated and opened to receive the universal shaft (3).

Bellow of a flexible material for protecting a coupling comprising first and second connector end subject to vibration and torsion. The bellow comprises a material able to prevent material from entering or exiting the space between the connector ends. The bellow is arranged to be attached to the first connector end by a first clamp and to the second connector end by a second clamp. The bellow is provided with a zipper comprising a zipper slider and first and second zipper part attached to opposite ends of the sheet. Thus, the bellow can be wrapped around said first connector end and second connector end and closed by zipper.

A split boot design for applications that contain Constant Velocity (CV) joints and/or other bearing assemblies where boots and/or covers are employed for, e.g., protection from the outside environment, assisting in retaining lubrication for the assembly, etc. A split boot design in accordance with an aspect of the present disclosure includes zippers along one or more axial seams, providing easier replacement of the boot and decreased manufacturing costs.

A novel split boot design for applications that contain CV joints and/or other bearing assemblies where protective boots or similar covers are required to protect the CV joint or bearing assembly from the outside environment while helping to retain necessary lubrication for the CV joint or bearing assembly. The new split boot design includes zippers along one or more axial seams which represents a significant departure from currently available split boot designs, and is more producible than prior protective boot designs with zipper closures. This new split boot design will simplify protective boot installation and/or replacement by reducing installation and/or repair time, and, thereby, overall cost.
