7-SPEED TRANSMISSION

摘要

The invention relates to a 7-speed transmission (1) for a motor vehicle, in particular for a sports car, with an input or primary shaft (8), an output or secondary shaft (9), a first, a second, a third, a fourth, a fifth, a sixth and a seventh forward speed (from VI to V7), as well as a reverse speed (R). In order to obtain a compact constructional design with a small transversal size and allow a sporty drive mode in the upshift from the first to the sixth speed, in which the shift process occur in an overlapping manner and almost without any interruption of the drive force, according to the invention the eight speeds (VI, V2, V3, V4, V5, V6, V7 and R) are combined in pairs into four shift groups (SI, S2, S3, S4), two (SI, S2 and S3, S4, respectively) of the four shift groups (SI, S2, S3, S4) are arranged on the input or primary shaft (8) and two on the output or secondary shaft (9), respectively, and at least between the first speed (VI) and the sixth speed (V6) adjacent speeds (VI, V2; V2, V3; V3, V4; V4, V5; V5, V6) are arranged in different shift groups (SI, S2, S3, S4).
