Method for establishing a neutral state in an automated stepped transmission |
摘要 |
<p>The method involves providing a shifting clutch for engaging and releasing a gear ratio of a stepped transmission e.g. double clutch transmission. The shifting clutch is provided with synchronizing devices, which are actuatable by a transmission actuator. The shifting clutch is actuated in a direction of engagement in a neutral condition of the transmission and in an operating condition of a motor vehicle. A starting gear ratio is assigned to the shift coupling, and a transmission input shaft of the stepped transmission is decelerated. An independent claim is also included for a device for shifting an automated stepped transmission of a motor vehicle.</p> |
