Title:
Dual clutch transmission
Document Type and Number:
Japanese Patent JP6243531
Kind Code:
B2
Abstract:
The invention relates to a dual clutch transmission comprising two input shafts (11a, 12a; 11b, 12b) which are provided for respectively linking to a power shift clutch (K1a, K2a; K1b, K2b), a first countershaft (13a; 13b) arranged offset parallel to the input shafts (11a, 12a; 11b, 12b), a second countershaft (14a; 14b) arranged offset parallel to the input shafts (11a, 12a; 11b, 12b), at least five gear wheel planes (Z1a-Z5a; Z1b-Z5b) which each comprise a fixed gear (Z11a-Z51a; Z11b-Z51b) permanently connected in a rotationally fixed manner to one of the input shafts (11a, 12a; 11b, 12b), wherein one of the gear wheel planes (Z4a; Z4b) comprises an idler gear wheel (Z42a; Z42b) arranged coaxially relative to the first countershaft (13a; 13b) and an idler gear wheel (Z43a; Z43b) arranged coaxially relative to the second countershaft (14a; 14b), which form a gear wheel pair for shifting into at least one reverse transmission gear (R1a, R2a), at least nine shift units (S1a-S9a; S1b-S9b) for producing an operative connection between the input shafts (11a, 12a; 11b, 12b) and/or the countershafts (13a, 14a; 13b, 14b), which in connection with the gear wheel planes (Z1a-Z5a; Z1b-Z5b) are provided at least constructively for shifting of at least eight sequentially shiftable forward transmission gears (V1a-V8a) and the at least one reverse transmission gear (R1a, R2a), an output (Z01a; Z01b) permanently connected in a rotationally fixed manner to the first countershaft (13a; 13b), and an output gear wheel (Z02a; Z02b) permanently connected to in a rotationally fixed manner to the second countershaft (14a; 14b).
