Description

technical field

[0001] The present invention relates to a transmission having a plurality of clutches which may be arranged in a dual clutch form, a hydraulic control system and components suitable for such a hydraulic transmission control system (such as proportional regulating valves) and a suitable transmission hydraulic system run method. Background technique

[0002] Multi-clutch transmissions in automobiles are primarily referred to as "dual-clutch transmissions" and there are numerous variant types denoted by this concept, which differ primarily in the number of gears (e.g. whether there are six, seven or more forward gear), how to realize the way and method of reverse gear in the transmission, and the working mode of the transmission.

[0003] Some dual-clutch transmissions can be referred to, for example, by printed instructions. For example, FR 2848629B1 (patent applicant: Renault SAS; application date: December 12, 2002) suggests that the same shift fork can be ...
