Gear shift device for transmission

Abstract

The invention provides a gearshift device for transmission capable of restraining stroke quantity of the gearlever and increasing the operability of the gearlever at the same time without high-precision enactment so as to realize steady switching operation. The gearshift device for transmission transfers operating force of the switching operation of the gearlever and makes the gear of the synchronizer selectively slide so as to change gear. The gearshift device for transmission includes selection shaft connecting to the gearlever; the first switching arm fastened to the selection shaft and rotatable corresponding to the switching operation of the gearlever; the second switching arm rotatably mounted at the shaft; the force application unit applying force in the way of lining up the first switching arm and the second switching arm; reverse shift fork shaft with the reverse shift fork fastened; and the switching part installed in the reverse shift fork shaft and selectively touching with the first switching arm and the second switching arm, and being able to change gear corresponding to the rotation of the first switching arm and the second switching arm.

Description

technical field [0001] The present invention relates to a shifting device of a transmission, which is configured to selectively actuate a synchronous meshing mechanism through a shift fork, so as to transmit power through a transmission gear train. Background technique [0002] Generally, in a manual transmission (manual transmission, MT), when the driver manually operates the shift lever (change lever), the operating force is transmitted to the shift fork through the shift device, and the synchronous meshing mechanism is activated by the shift fork. Thereby establishing the desired shift stage. Such a synchromesh mechanism is arranged on one of the shafts corresponding to the constant mesh type transmission gear train arranged in parallel between two parallel shafts. [0003] The operating force (shifting force) transmission system in such a transmission, as described in Japanese Patent Laid-Open No. 2003-14114, includes: a shift select shaft, which is pushed and pulled by...

AI Technical Summary

Problems solved by technology

[0010] In the shifting device of the transmission disclosed in Patent Document 2, the operability of the shift lever is improved while suppressing the stroke amount of the shift lever. If the shape of the shift arm is not set with high precision, it will be difficult to produce an effect, and there is a problem that it is difficult to obtain a large shift variable amount due to restrictions on the shape of the shift arm.
