Embodiment Construction

[0051] The following description is merely exemplary in nature and is not intended to limit the disclosure, application or uses.

[0052] Referring now to the drawings, a hub and sleeve assembly for a manual transmission is shown in figure 1 , and denoted by reference numeral 10. The hub and sleeve assembly 10 includes a hub 12 and a sleeve 14 .

[0053] further reference Figure 3A , 3B and 3C, the hub 12 includes two identical faces 20 and 22 , and a set of teeth 16 around the periphery of the hub 12 . Hub 12 also includes an inner bore 13 with a set of teeth 18 including individual teeth 19 . In the arrangement shown, the set of teeth 16 is divided into three spaced apart sections by gaps 30 . Within each section, the set of teeth 16 comprises individual teeth 17 throughout the set of teeth 16 . Between each tooth 17 is a platform 36 . However, at the end of each portion of the tooth 16 there is a shallower land 38 than the land 36 .

Abstract

The invention relates to a transmission hub and s sleeve assembly. The assembly includes a hub and a sleeve in which the hub resides. The hub includes a first set of teeth and the sleeve includes a second set of teeth that engages with the hub's first set of teeth. The sleeve includes at least one tooth that has a reduced height compared to the rest of the sleeve's teeth, and the hub has a set of landings with at least one landing that is shallower than the rest of the landings of the hub. The hub and sleeve are configured such that the at least one tooth of reduced height resides in the at least one shallower landing. The hub further includes a first face and a second face that has the same configuration as the first face. The combination of the same first face and second face and the reduced tooth height and shallower landing provides a hub and sleeve assembly that can be assembled in one of only six functional configurations.

Description

[0001] related application [0002] This application claims the benefit of U.S. Provisional Patent Application No. 62 / 076,845, filed November 7, 2014. [0003] The entire content of the above application is incorporated herein by reference. technical field [0004] The present disclosure relates to a hub and sleeve assembly for a manual transmission. Background technique [0005] The statements in this section merely provide background information related to the present disclosure and may or may not constitute prior art. [0006] A typical motor vehicle transmission includes many components that interact during transmission operation. For example, manual transmissions typically include a synchronizing system with a hub and sleeve assembly. During the manufacturing process of the transmission, there is the possibility that the hub and sleeve are assembled incorrectly. [0007] Accordingly, a need exists for a transmission hub and sleeve assembly that minimizes or reduces ...
