Abstract

A driving system with an automatic transmission capable of driving a vehicle when an engine is stalled is provided with an electromagnetic clutch 11 between an output shaft 2 of an engine 1 and a ring gear 3 which is engaged by a starter motor 7 for actuating the engine 1. In order to drive a vehicle in an emergency when the engine 1 is stalled, for example, the output shaft 2 of the engine 1 is disconnected from the ring gear 3 by the electromagnetic clutch 11 so that a torque converter 4 and a transmission 5 are separated from the engine 1 and released, and the starter motor 7 is actuated. Thus, the transmission 5 is driven via the ring gear 3 and the torque converter 4 to drive wheels via a drive shaft 6.

Claims

1. In a driving system with an automatic transmission in which driving force of an engine is transmitted to wheels via a torque converter and the transmission, the driving system comprising:

a clutch which connects and disconnects the engine to and from the torque converter, and

a driving device which actuates the transmission.

2. The driving system as claimed in claim 1, wherein the driving device actuates the transmission through the torque converter.

3. The driving system as claimed in claim 1, wherein the driving device directly actuates the transmission.
