Problems solved by technology

Therefore, the dual clutch of the existing structure not only has the disadvantages of complex manufacturing process and high processing cost, but also has two rotating oil grooves axially arranged on the outer sleeve of the main hub, which increases the axial length of the dual clutch and affects To the space layout of the whole vehicle, it also brings the problem of mutual leakage of oil in the two rotating oil tanks

Abstract

The invention discloses a dual-clutch structure which is used for solving the problems that the processing process of a main hub is complex, the assembling quality is difficult to guarantee and the structure is not compact. The dual-clutch structure comprises an input shaft, a clutch front cover, a main hub, an outer clutch, an inner clutch, an output shaft I and an output shaft II, wherein one end of the improved input shaft is connected to an engine shaft, while the other end of the input end is connected to the clutch front cover; the clutch front cover is assembled with an outer clutch element; the main hub is in an integral structure and is sleeved outside the output shaft II by means of clearance fit; the outer and inner clutches are arranged on the corresponding elements of the main hub; the output shaft I is assembled with the outer clutch element; and the output shaft II is assembled with an inner clutch element. As the main hub of the double clutches is designed to be in the integral structure, the number of the main hub parts and the manufacturing cost of the double clutches are reduced, the working performance of the double clutches is guaranteed, and the axial sizes of the double clutches are reduced, thereby being beneficial for the space distribution of the integral car.

Description

technical field [0001] The invention relates to a dual-clutch structure of an automobile dual-clutch transmission, which belongs to the technical field of automobiles. Background technique [0002] The dual-clutch mechanism of the dual-clutch transmission is generally composed of an input shaft, two friction clutches, two output shafts, a housing fixed on the main hub, and two sets of piston devices installed on the housing. Its structural features are: friction The input element of the clutch is connected to the input shaft, the output element of the friction clutch is always connected to one of the two output shafts, and the friction clutch can be braked in any case by one of the piston devices mounted on the housing , the dual clutch device is also provided with a thrust bearing. Therefore, the dual-clutch transmission can shift gears by means of overlapping actions of the dual clutches, avoiding power interruption during the shifting process. [0003] At present, the d...
