PROTECTIVE COVER STRUCTURE FOR THE SLIP ASSEMBLY

Abstract

Disclosed is a protective cover structure of the drive shaft that provides power transmission in vehicles in the automotive sector. The protective cover structure is used in slip assemblies with a yoke shaft and a sliding sleeve and includes a protective cover tube in the form of a straight tube which is connected to a yoke shaft at one end and a sliding sleeve connected to the same with a yoke shaft. A double-lipped seal or a three-lipped seal or a flexible spring-energized seal is then connected to the end of the protective cover tube on the side of the sliding sleeve and provides sealing between the protective cover tube and the sliding sleeve, with a carrier body that connects the end of the protective cover tube to the double-lipped seal or three-lipped seal or the flexible spring-energized seal to the protective cover tube.

Claims

DETAILED DESCRIPTION OF THE INVENTION

[0037] In this detailed description, the preferred alternatives of the inventive protective cover structure are described only for clarifying the subject matter such that no limiting effect is created.

[0038] In FIG. 1, the disassembled view of the inventive protective cover is given. Accordingly protective cover mainly comprises the following; a protective cover tube (10) in the form of a straight tube which is connected to a yoke shaft (40) at one end and a sliding sleeve (50) connected to the same with a yoke shaft (40), double-lipped seal (20a) or three-lipped seal (2b) or flexible spring-energized seal (20c) which are connected to the end of the protective cover tube (10) on the side of the sliding sleeve (50) and work on the sliding sleeve (50) and provide sealing, carrier body (30) that connects the end of the protective cover tube (10) to the double-lipped seal (20a) or three-lipped seal (2b) or the flexible spring-energized seal (20c) to the protective cover tube (10).

[0039] The protective cover tube (10), which constitutes the main structure of the inventive protective cover structure, is shaped in the form of a straight tube. As can be seen in FIG. 2, a yoke shaft (40) is connected to one end of the protective cover tube (10). On the other hand, the sliding sleeve (50) is connected to the protective cover tube (10) by passing through the other end of the protective cover tube (10) and being intertwined with the yoke shaft (40). A double-lipped seal (20a) or a three-lipped seal (2b) or a flexible spring-energized seal (20c) is placed at the end of the protective cover tube (10) so as to provide sealing between the protective cover tube (10) and the sliding sleeve (50).

[0040] The lips of the double-lipped seal (20a) or a three-lipped seal (2b) or a flexible spring-energized seal (20c) have flexible structure, they are made of different materials to be compatible with the surface where it provides sealing.

[0041] A carrier body (30) is engaged to the end of the protective cover tube (10) such that it contains the double-lipped seal (20a) as seen in FIG. 3, three-lipped seal (20b) as seen in FIG. 4 and flexible spring-energized seal (20c) as seen in FIG. 5 for fitting double-lipped seal (20a) or three-lipped seal (20b) or flexible spring-energized seal (20c) into end of protective cover tube (10). The grip surface (31) at the lower end of said carrier body (30) extends into the protective cover tube (10). Thus, it is ensured that the carrier body (30) is fixed to the end of the protective cover tube (10).

[0042] In the inventive protective cover tube, sealing is provided between the protective cover tube (10) and the sliding sleeve (50) by connecting the double-lipped seal (20a) or the three-lipped seal (2b) or the flexible spring-energized seal (20c) to the end of the protective cover tube (10) in the form of a straight tube by means of the carrier body (30).
