- FIG. 8 for the individual gears the power flow of the dual clutch transmission also shown in FIG. Fig. 9 in a table, the corresponding positions of the sliding sleeves and the two clutches of the
- the dual-clutch transmission 100 shown in FIG. 1 has seven or eight forward gears Vl to V8 and two reverse gears Rl, R2. All forward gears Vl to V8 are sequentially continuously load-switchable. Likewise, the two reverse gears Rl, R2 are power shiftable with each other.
- an input shaft 10 is connected to a main shaft 20 through a first partial transmission 22 and a second partial transmission 24, which are arranged parallel to one another in the force flow.
- the partial transmissions 22, 24 have
- an intermediate shaft 12, 14 is concentric with the second intermediate shaft 12. Both intermediate shafts 12, 14 are arranged coaxially with the input shaft 10 and can each be operatively connected via the load clutch Kl, K2 with the input shaft 10.
- the first intermediate gear 22 associated second intermediate shaft 12 is on the one hand with the main ⁇ shaft 20 through the sliding and disengaging sliding sleeve Sl to form a direct fifth forward gear V5 and on the other hand through this sliding sleeve Sl via a mattersslosrad 41 and with this intermeshing fixed wheel 51 a second input constant E2 operatively connected to a main shaft 20 parallel, designed as a hollow shaft countershaft 18.
- the hollow shaft 18 is thus associated with the first partial transmission 22 and can be brought into power flow with the main shaft 20 by a first gear pair Z1 to form the highest forward gear V7 or the two highest forward gears V7, V8.
- the gear pair Zl comprises a coaxially arranged on the main shaft 20 idler gear 1 and a coaxial rotatably mounted on the hollow shaft 18 fixed gear 2.
- the seventh or eighth forward gear V7 and V8 is respectively formed by the arranged behind the idler gear 1 second Sliding sleeve S2 is moved forward, so that a rotationally fixed connection between this idler gear 1 and the main shaft 20 is made.
- a first input constant E1 is provided, which comprises an input fixed wheel 50 arranged coaxially in rotation with respect to the hollow intermediate shaft 14 and a fixed wheel 52 arranged coaxially with respect to rotation with respect to an inner shaft 19.
- the drive torque is passed to the gear pair Zl, the seventh and the eighth forward gear V7 or V8 is inserted.
- a second gear pair Z2 is arranged. This also includes a coaxially arranged on the main shaft 20 idler gear 3 and a coaxial rotation on the hollow shaft 18 arranged fixed gear 4. If the arranged between the two idler gears 1, 3 second sliding sleeve S2 moved backwards, so this provides a rotationally fixed connection between the main shaft 20 and the idler gear 3 ago.
- This inner shaft 19 has at its front end a fixed wheel 52 of the first input constant El.
- the region of the inner shaft 19 with this fixed wheel 52 thus projects out of the hollow shaft 18 at the front.
- another area of the inner shaft 19 projects out of the hollow shaft 18.
- This area carries in the successive from front to back succession the third sliding sleeve S3, a loose wheel 5, a fixed gear 6 and a fixed gear 7.
- the third sliding sleeve S3 either the hollow shaft 18 or the idler gear 5 with the inner shaft 19 can be coupled.
- this idler gear 5 meshes with a coaxial rotation on the main shaft 20 arranged fixed wheel 8.
- the idler gear 5 and the meshing with this fixed wheel 8 are thus the third Gear level Z3 assigned.
- This third gear level Z3 is assigned to the sixth forward gear V6.
- a fourth gear pair Z4 is provided, via which the first and the second forward gear Vl, V2 extends.
- the fourth sliding sleeve S4 is arranged coaxially with the main shaft 20. If this sliding sleeve S4 is displaced forward, it establishes a rotationally fixed connection between a loose wheel 30 of the fourth gear pair Z4 and the main shaft 20. On the other hand, if the sliding sleeve S4 is displaced to the rear, it establishes a rotationally fixed connection between a loose wheel 31 of a toothed wheel chain ZK and the main shaft 20.
- the gearwheel chain ZK also comprises an intermediate gear 32 which, on the one hand, meshes with the idler gear 31 and, on the other hand, with the rearmost fixed gear 7.
- this intermediate wheel 32 is shown folded into the plane of the drawing.
- the two gear pairs Z2 and Z4 are each used with a loose wheel 3, 30 on the main shaft 20 for the realization of two different forward gears Vl to V4.
- the first gear pair Z1 can be used both for only one forward gear V7 and alternatively for two forward gears V7 and V8.
- the dual-clutch transmission builds axially shorter than comparable known transmission concepts.
- the inner shaft 19 is comparatively long. If the dual-clutch transmission is connected to a high-torque drive motor or is designed by the gear sizes such that high torques are transmitted, then a lateral buckling of the inner shaft 19 can be excluded with certainty that, as shown in FIG. 2, an intermediate wall 40 used for an additional bearing becomes.
- This intermediate wall 40 may be arranged such that it supports the main shaft 20 in the region of its transmission input end.
- the coaxial with the inner shaft arranged - and mounted on this - hollow shaft 18 are also stored on this intermediate wall 40 in addition.
- the main shaft 20 is mounted in the manner of a so-called pilot bearing in a blind bore 42a of the inner intermediate shaft 12.
- the blind bore extends up to an axial installation space of the input idler gear 41 of the second input constant E2.
- the blind bore 42b can be pulled even deeper into the inner intermediate shaft 12.
- the pilot bearing is relatively close to the storage of the outer intermediate shaft 14, so that the free support length of the inner intermediate shaft 12 is shorter.
- the intermediate wall 40 according to FIG. 2 can be dispensed with.
- the pilot bearing is preferably designed as a rolling bearing. Since in the described embodiment, the radial space is very tight, the storage of the matterslosrades 41 of the two ⁇ th input constant E2 relative to the inner intermediate shaft 12 is preferably designed as a sliding bearing. Due to the double or triple double use of the gear pairs Z2, Z4 and optionally also Zl the gear jumps are not completely free selectable. The following restrictions apply to the step jumps ⁇ :
- a progressive gradation of the dual-clutch transmission in the execution with eight forward gears is not possible.
- a geometric or approximately geometric gradation of the forward gears can be selected. In an ideal geometric gradation all gear jumps would be identical. In practical implementation, for example, the gear jump ⁇ v 2 / v 3 can be selected to be greater than the remaining gear jumps.
- FIG. 4 shows, based on a diagram in FIG. 4, the gear steps in a first quasi-progressive gradation.
- the eighth forward gear V8 is shown with, although this remains unused in many transmission designs.
- Fig. 5 shows by way of a diagram the gear jumps in a second quasi-progressive gear gradation.
- the eighth forward speed V8 is also shown here, although this remains unused in many transmission designs. The transmission design takes place with the gear jumps ⁇
- the gear jump ⁇ 2/3 can be chosen such that the first three gear jumps - at least approximately - identical.
- the eighth forward gear can not be used in practice in many cases, since the gear jump ⁇ v7 / vs would be too large, in particular compared to the gear jumps ⁇ V 6 / v7 and ⁇ vs / v ⁇ .
- the dual-clutch transmission can be designed with a geometric gear pitch according to FIG. 6. In this case, all gear jumps are approximately the same size, so that the gear jump (pv7 / vs does not stand out unpleasantly ⁇ .
- Fig. 6 shows by means of a diagram the gear jumps in a strictly geometric gear gradation.
- one or more gear jumps greater than the remaining gear jumps can be selected, deviating from a purely geometric gradation.
- Fig. 7 shows a design in which the gear jump ⁇ V 2 / v3 is slightly larger.
- Fig. 7 shows a diagram of the Gear jumps in a third quasi-geometric gear gradation.
- this direct gear the two countershafts can be rotationally decoupled by the sliding sleeves S2, S3 and S4 are each brought into their neutral position and the first clutch Kl is kept open. As a result, splashing and ventilation losses in the dual-clutch transmission can be kept low.
- FIG. 8 shows the power flow of the dual-clutch transmission also shown in FIG. 1 for the individual gears.
- Fig. 9 shows in a table, the corresponding positions of the sliding sleeves Sl to S4 and the two clutches Kl, K2. Accordingly, the switching logic for realizing the respective gears is shown in Fig. 9.
- the sliding sleeves Sl to S4 in a forward position v, a rear position h and a central neutral position N are located.
- the switching logic can also be designed such that the number of required adjusting movements on the sliding sleeves S1 to S4 is reduced compared to FIG. This results in each deviating shift strategies, depending on whether an upshift or downshift is expected as the next gear change.
- a switching table is shown by way of example, in which the number of setting movements on the sliding sleeve S1 are respectively reduced with regard to the next upshifting operation.
- switching strategy can be applied, which additionally reduces the actuating movements of the remaining sliding sleeves S2 to S4.
- a strategy also not shown here can be used, which reduces the number of actuating movements in terms of downshifts.
