Abstract

The invention provides a synchronizer apparatus for a transmission, which includes: first and second shifting gears rotatable on an output shaft; a hub spline-coupled with the output shaft and havinga slope portion having slanted surfaces; a sleeve spline-coupled with the hub; a key coupled with a recess of a slope portion; first and second clutch gears disposed between the hub and shifting gears; first and second outer rings and first and second inner rings disposed between the hub and clutch gears; first and second synchronizer cones disposed between the first inner and outer rings and thesecond inner and outer rings; a poppet ball unit disposed at the sleeve and contacting the key through a poppet ball; first and second push blocks disposed at the slanted surfaces; and first and second push springs inserted in spring holes formed at the push blocks to force push blocks to the slanted surfaces.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2018-0157490 filed on December 7, 2018, the entire contents of which are incorporated herein by reference. technical field [0003] The invention relates to a synchronizer device for a transmission. Background technique [0004] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0005] A synchronizer device for a vehicle transmission is generally a device for synchronously coupling a shift gear (ie, a transmission gear) to an output shaft through operation of a shift fork. [0006] figure 1 is a cross-sectional view of a typical synchronizer device used in a transmission. [0007] refer to figure 1 , in a typical synchronizer device for a transmission, a hub 3 is spline-coupled with an output shaft 1, and a sleeve 5 is arranged on teeth on the out...
