Abstract

The present invention discloses a synchronizer used for a transmission. The synchronizer comprises a sleeve having a gear-shifting gear. A synchronization key is arranged to a hub so as to protrude towards the sleeve. A synchronizer locking ring is arranged around the circumference of the hub. A transmission gear can be arranged around the synchronizer locking ring in a freely rotating way, and is provided with a clutch gear facing to the sleeve in the circumferential direction. The gear-shifting gear can have different gear teeth thicknesses based on a contact state relative to the synchronization key, so that the gear teeth thicknesses when the gear-shifting gear is contacted with the synchronization key is larger than the gear teeth thicknesses when the gear-shifting gear is not contacted with the synchronization key.

Description

technical field [0001] The present invention relates generally to a synchronizer for a transmission, and more particularly to a synchronizer for a transmission in which the shape of the sleeve teeth is altered to reduce the pressure exerted on the surfaces of the synchronizer keys, and Reduced travel of the sleeve for easier lever operation and the ability to remove the stop pin, saving cost and weight of the synchronizer. Background technique [0002] Generally speaking, a synchronizer for a transmission is a part of a synchronous manual transmission that is manipulated and driven by a transmission lever through a transmission mechanism to respectively control the rotational speed of a pair of transmission gears provided on the input shaft and the output shaft (RPM) to allow the pair of gears to mesh smoothly, thereby preventing the transmission from jolting. [0003] refer to figure 1 , the synchronizer is configured such that its hub 2 is coupled to the rack of the pini...
