Embodiment Construction

[0059] The following description is merely exemplary in nature and is not intended to limit the present disclosure, application or uses.

[0060] refer to figure 1 , shows a synchronizer and is generally designated by reference numeral 10 . The synchronizer 10 is preferably used in a manual or automatic transmission of a motor vehicle (not shown). Synchronizer 10 is shown in operative engagement with a first component of the transmission, such as shaft 12 , and with a second component of the transmission, such as gear 14 . It should be appreciated that the first and second components may be other components such as a combination of gears or shafts or stationary components without departing from the scope of the present invention. Shaft 12 rotates about an axis of rotation 16 and includes a splined portion 18 . The gear wheel 14 is arranged concentrically to the shaft 12 and rotates about an axis of rotation 16 . Gear 14 includes external gear teeth 20 and gear spline teeth...

Abstract

A synchronizer for a transmission of a motor vehicle is provided. The synchronizer includes a sleeve and a blocker ring. The sleeve includes sleeve spline teeth and advanced sleeve spline teeth. The blocker ring includes blocker spline teeth. The sleeve spline teeth and blocker spline teeth are each asymmetrical and have a blunt tip, a first angled side, and a second angled side. The first and second angled sides have different angular relationships to a longitudinal axis of the teeth.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application No. 62 / 134,257, filed March 17, 2015. The disclosures of the aforementioned applications are incorporated herein by reference. technical field [0003] The current disclosure relates to a synchronizer for a transmission having asymmetrical blocker teeth and sleeve teeth, and more particularly to a synchronizer having asymmetrical shallow angle blocker and sleeve teeth , with a front sleeve gear indexing teeth (indexing teeth). Background technique [0004] The statements in this section merely provide background information related to the present disclosure and may or may not constitute prior art. [0005] Synchronizers, or dog clutches, are used in automatic and manual transmissions to synchronize the speed of two components before the two components engage. Typically, a synchronizer includes a sleeve and a stopper ring. A sleeve has a set of teeth and...
