| 摘要 |
The invention relates to a CVT transmission for an essentially continuously variable transmission of a torque, comprising a first conical disk pair on the input side having a first adjusting disk moving in the axial direction relative to a first counter disk, a second conical disk pair on the output side having a second adjusting disk moving in the axial direction relative to a second counter disk, and further comprising a belt means which is received by the first and the second conical disk pair for transmitting the torque from the first conical disk pair to the second conical disk pair, an essentially electrically driven first adjustment device for pressing the belt means between the first counter disk and the first adjusting disk and an essentially electrically driven second adjustment device for pressing the belt means between the second counter disk and the second adjusting disk. According to the invention, the second adjustment device can be actuated independently from the first adjustment device for varying the pretension of the belt means. As a result, the CVT transmission is characterized by little wear over a high torque range. |
