| description | PROBLEM TO BE SOLVED: To shorten a period of torque interruption while suppressing drop in transmission torque by torque interruption during switching of shift stages, in a transmission device for electric vehicle with a synchro mechanism.SOLUTION: A transmission device 10 is used for an electric vehicle driven by an electric motor EM. The transmission device 10 includes: an input shaft 1 in which power is inputted from the electric motor EM; an output shaft 2 arranged in parallel with the input shaft 1; a main transmission unit 3; and a transmission assist unit 4. The main transmission unit 3 includes a low speed side shift stage 3L and a high speed side shift stage 3H, and a synchro mechanism 8 for performing switching between these shift stages 3L, 3H, and it changes the rotational speed inputted in the input shaft 1 and transmits it to the output shaft 2. The transmission assist unit 4 has a transmission ratio smaller than the high speed side shift stage 3H, and transmits power from the input shaft 1 to the output shaft 2 when switching the shift stages of the main transmission unit 3.SELECTED DRAWING: Figure 1
【課題】シンクロ機構付きの電動車両用変速装置において、変速段の切り換え時におけるトルクインタラプションによる伝達トルクの落ち込みを抑えるとともに、トルクインタラプションの期間を短くする。【解決手段】この変速装置１０は、電動機ＥＭにより駆動される電動車両に用いられる。変速装置１０は、電動機ＥＭから動力が入力される入力軸１と、入力軸１と平行に配置された出力軸２と、主変速ユニット３と、変速アシストユニット４と、を備えている。主変速ユニット３は、低速側変速段３Ｌ及び高速側変速段３Ｈと、これらの変速段３Ｌ，３Ｈの間で切り換えを行うためのシンクロ機構８と、を有し、入力軸１に入力された回転速度を変速して出力軸２に伝達する。変速アシストユニット４は、高速側変速段３Ｈよりも小さい変速比を有し、主変速ユニット３の変速段の切り換え時に入力軸１から出力軸２に動力を伝達する。【選択図】図１ |
