Problems solved by technology

[0008] In addition, with regard to the shifting device of the conventional dual-clutch transmission, since only one follower pin of the shift fork is inserted into the cam track, there is a problem that the size of the shifting device of the dual-clutch transmission is relatively large as a whole. , Moreover, there is the problem of being unable to cope with the position change and size limitation of the shifting device

Embodiment Construction

[0043] Referring to the accompanying drawings, an embodiment of the shifting device of the dual-clutch transmission of the present invention will be described below.

[0044] Such as Figure 1 to Figure 3 As shown, the dual-clutch transmission that has applied the shifting device of an embodiment of the present invention is composed of dual-clutch (10), drive gear portion (20), transmission gear portion (30), synchronizer portion (40), shift fork Part (50) and double cam mechanism (60) constitute.

[0045] The dual clutch (10) receives the transmission of the rotational force generated by the engine (not shown) through the first clutch (11) or the second clutch (12), and selectively transmits the transmitted rotational force to the first input shaft (13) or the 2nd input shaft (14). The dual clutch (10) selectively transmits the rotational force to the first input shaft (13) or the second input shaft (14) through hydraulic control. Since this configuration applies a well-kno...

Abstract

Provided is a shifting apparatus of a dual clutch transmission, including: a plurality of drive gears mounted onto a first input shaft (13; 213) or a second input shaft (14; 214) of dual clutches (11, 12; 211, 212); a plurality of transmission gears meshing with the drive gears, respectively, and each mounted onto a first support shaft (15; 215) or a second support shaft (16; 216); a plurality of synchronizers (S1-S4) positioned between the transmission gears and each slidably mounted onto the first support shaft or the second support shaft; a plurality of shift forks (51-54; 251-254) connected to the synchronizers and each having a follower pin (51a-54a; 251a-254a); and a dual cam mechanism (60; 260) connected to the follower pins of the shift forks to move the shift forks by rotation so that the synchronizers slidably move to be engaged with the transmission gears along the first support shaft or the second support shaft.

Description

technical field [0001] The present invention relates to a shifting device of a dual-clutch transmission, in particular to a shifting device of a dual-clutch transmission capable of improving operational reliability during shift control and product durability. Background technique [0002] Dual Clutch Transmission (DCT; Dual Clutch Transmission), like a manual transmission, has the characteristics of small power loss, easy operation, and fast shifting time. In the gear shifting method using a dual clutch transmission, assuming that the transmission is shifting from 1st to 6th speed, if the No. 1 clutch is driving in the 1st speed, the No. 2 clutch is on standby in the state of pre-shifting to the 2nd speed. The method is to cut off the power of the No. 1 clutch and connect the No. 2 clutch when shifting is started. If you enter the 2nd gear and drive, then the No. 1 clutch is dialed out of the 1st gear, and the gear is shifted to the 3rd gear, and then only waits for the clu...
