Problems solved by technology

According to such a structure, the axial length of the transmission can be shortened, but this transmission has a complicated structure in which the output shaft extends to the front part of the transmission, and thus requires a complicated operation of engaging the clutch when switching gears.

Embodiment Construction

[0057] Hereinafter, the dual-clutch transmission of the present invention will be described based on the drawings. figure 1 It is a schematic diagram showing an embodiment of the dual-clutch transmission of the present invention, figure 2 It is a figure showing the structure of the switching clutch provided on the intermediate shaft. exist figure 1 in, right with Figure 11 Corresponding components such as those in the conventional dual-clutch transmission are denoted by the same reference numerals.

[0058] Such as figure 1 As shown, in the dual-clutch transmission of this embodiment, a first input shaft S1 and a second input shaft S2 formed in a double pipe structure are arranged, and the first input shaft S1 penetrates through the hollow second input shaft S2 and extends rearward. A first friction clutch C1 and a second friction clutch C2 arranged in parallel in the axial direction are arranged in front of the two input shafts, and the input side of each friction clu...

Abstract

[Abstract] A dual clutch type transmission having two input shafts coupled to friction clutches and having a plurality of gear trains, featuring small structure and simplified gear shift operation. An intermediate shaft S3 disposed in parallel with two input shafts S1, S2 has a double tubular structure including a hollow outer shaft S3O and a center shaft S3I extending through the hollow portion thereof, an output shaft S4 is driven by the rear end of the center shaft S3I, and a plurality of gear trains are disposed between the outer shaft S3O and the input shafts S1, S2. A reduction gear RG is freely fitted onto the center shaft S3I, and a changeover clutch CC is provided between the outer shaft S3O and the reduction gear RG to change over the rotational speed of the center shaft S3I in two steps. Thus, a transmission of a small size is constituted having a decreased number of gear trains and a decreased distance between the input shafts and the intermediate shaft . The changeover clutch CC is changed over for only the center gear, and therefore a simple operation device may be used.

Description

technical field [0001] The present invention relates to a dual-clutch transmission, which is a transmission in a power transmission device of a vehicle, and includes two transmission input shafts coupled to an engine via friction clutches, and controls the two friction clutches while shifting gears. Gear shifting is performed while engaged. Background technique [0002] In recent years, various power transmission devices for automatic vehicles have been developed in order to facilitate vehicle driving and reduce driver fatigue. A typical automatic transmission is a combination of a torque converter and a planetary gear mechanism, and it is widely used as a power transmission device of a so-called automatic transmission vehicle (AT vehicle). In addition to the automatic transmission, there is a power transmission device that uses the same parallel shaft gear mechanism type transmission as a manual transmission car (MT car), combines it with an automatic operation clutch, and...
