Abstract
A system for actuating gear changes in a motor vehicle transmission includes an electric motor including a motor shaft supported for rotation about an axis, first and second actuator drums supported for rotation substantially parallel to the axis, and a drive mechanism including a first power path driveably connecting the motor shaft and the first drum, and a second power path driveably connecting the motor shaft and the second drum.
Claims17
An actuation system for producing gear changes in a multiple gear transmission for a motor vehicle comprising:
- a first electric motor including a first motor shaft supported for rotation about a first axis;
- first and second actuator drums supported for rotation substantially parallel to the first axis;
- a first drive mechanism including a first power path driveably connecting the first motor shaft and the first drum, and a second power path driveably connecting the first motor shaft and the second drum.
An actuation system for producing gear changes in a multiple gear transmission for a motor vehicle comprising:
- a first electric motor including a first motor shaft supported for rotation about a first axis;
- first and second actuator drums supported for rotation substantially parallel to the first axis;
- a first drive mechanism including:
- a first power path driveably connecting the first motor shaft and the first drum, and
- a second power path driveably connecting the first motor shaft and the second drum, and aligned in a first plane with the first power path;
- a second electric motor including a second motor shaft supported for rotation;
- third and fourth actuator drums supported for rotation substantially parallel to the first axis;
- and
- a second drive mechanism including:
- a third power path driveably connected to the second motor shaft and the third drum, and
- a fourth power path driveably connected to the second motor and the fourth drum, aligned in a second plane with the third power path.
An actuation system for producing gear changes in a multiple gear transmission for a motor vehicle comprising:
- a first electric motor including a first motor shaft supported for rotation about a first axis and extending to a first side of the first motor;
- first and second actuator drums and supported for rotation substantially parallel to the first axis;
- a first drive mechanism located on the first side of the first motor for driveably connecting the first motor shaft to the first drum and the second drum;
- a second electric motor including a second motor shaft supported for rotation and extending to the first side;
- third and fourth actuator drums supported for rotation substantially parallel to the first axis;
- and
- a second drive mechanism located on the first side for driveably connecting the second motor shaft to the third drum and the fourth drum.
