- a first clutch when engaged, transfers torque between the output shaft of an engine and a first input shaft of the transmission
- a second clutch when engaged, transfers power between the output shaft of the engine and a second input shaft of the transmission.
- the first and the second drive shaft are attached coaxially to each other.
- a first set of gears are mounted for rotation with the first drive shaft and a second set of gears are mounted for rotation with the second drive shaft, the first and second sets of gears rotatably mounted on one or more countershafts.
- the first and second gears and the gear with which they mesh are arranged to provide different gear ratios.
- the first set of gears attached to the first clutch provides first, third, fifth, and seventh speeds
- the second set of gears attached to the second clutch provide second, fourth, and sixth speeds, and a reverse gear.
- One of the gears of each pair of meshing gears is mounted on the attached shaft for rotation relative thereto and is selectively rotatably connected to the shaft by means of a synchronous switching unit.
- Each synchronous shift unit is positioned between a pair of gears so that movement of the synchronous shift unit axially toward one gear engages that gear and movement axially toward the other gear engages the other gear.
- the movement of the synchronous switching units is controlled by means of switching rulers, an attachment on each of the switching rulers engaging in a circumferential groove in the synchronous switching unit.
- the clutch that controls the gear engaged would be engaged while the other clutch is disengaged.
- a gear which is added to the other clutch can be engaged by suitable handling of the synchronous switching unit which is assigned to that gear, while the gear currently engaged remains engaged.
- the gear change is then carried out by simultaneously disengaging one clutch and engaging the other clutch in order to achieve a smooth transfer of the torque.
- a shift mechanism for a dual clutch transmission system includes:
- Shift ruler is designed to be a synchronous shift unit of a multi-stage
- Control gearbox characterized in that a shift drum for rotation about an axis is mounted parallel to an axis of the shift rulers, the shift drum for rotation being mounted on a control shaft; the shift drum having an annular groove, a shift finger extending from each of the shift rulers into the annular groove, the shift finger of the shift rulers being arranged around the groove in angularly spaced locations;
- annular groove in the shift drum has a first section with an axial width that provides a close clearance fit with the shift fingers of the shift rulers and a second section, the width of which is sufficient to allow axial movement of the shift finger on the shift rulers between a first position, in which a first gear, which is attached to the synchronous shift unit, which is controlled by the shift ruler, and a second position, in which a second gear, which is attached to the synchronous shift unit, which is controlled by the shift ruler, is engaged, with ramps in the walls of the groove are provided between the first and second sections;
- an axial slot is provided in the shift drum, the axial slot extending over the walls of the annular groove centrally from the second portion thereof;
- shift actuation means being provided on the control shaft, the shift actuation means extending through the axial slot;
- a forked shift control must therefore be provided either on the shift rulers or on the control shaft, so that the shift finger is arranged on the other component between the forked shift control, which makes movement in both directions possible.
