7速变速器
摘要：
本发明涉及一种用于机动车辆、特别是用于跑车的7速变速器（1），其具有输入轴或初级轴（8）、输出轴或次级轴（9）、第一、第二、第三、第四、第五、第六和第七前进档位（从V1至V7）、以及倒档档位（R）。为了获得具有小的横向尺寸的紧凑结构设计并允许在从第一至第六档位的升档中的运动行驶模式——其中换档过程以重叠方式并在驱动力几乎不发生任何中断的情况下发生，根据本发明，八个档位（V1、V2、V3、V4、V5、V6、V7和R）被成对结合在四个档位组（S1、S2、S3、S4）中，四个档位组（S1、S2、S3、S4）中的两个（S3、S4）被布置在输入轴或初级轴（8）上并且两个（S1、S2）被布置在输出轴或次级轴（9）上，并且至少第一档位（V1）与第六档位（V6）之间相邻的档位（V1、V2；V2、V3；V3、V4；V4、V5；V5、V6）被布置在不同档位组（S1、S2、S3、S4）中。
摘要（英）：

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).
