Clutch and peripheral assembly structure

Abstract

The invention belongs to the technical field of an AT (Automatic Transmission), and particularly relates to a clutch and peripheral assembly structure. The clutch and periphery assembly structure is characterized in that a middle separating plate is provided with a middle separating plate supporting shaft; two ends of the middle separating plate supporting shaft are respectively positioned at two sides of the middle separating plate; the middle separating plate supporting shaft between the middle separating plate and a planetary line is provided with a clutch; the clutch comprises a gear inner hub which is rotationally connected with the middle separating plate supporting shaft; an outer ring of the gear inner hub is provided with a gear; an inner ring of the gear inner hub stretches to the planetary line and is arranged on a clutch inner hub on the inner ring of the gear inner hub in a sleeving way; the outer side of the clutch inner hub is provided with a clutch outer hub which is fixedly connected with the gear; a planetary frame is fixedly connected with the clutch inner hub; a sun gear is fixedly connected with the gear inner hub; the planetary frame is provided with a hollow transmission shaft which is inserted into a hollow cavity of the middle separating plate supporting shaft and stretches to the other side of the middle separating plate; the gear change of the AT can be increased on the premise that the whole size of a gearbox has a little change, the fuel consumption can be further reduced, and the dynamic running performance can be further increased.

Description

technical field [0001] The invention belongs to the technical field of automatic transmissions, in particular to a structure of a clutch and peripheral components. Background technique [0002] In the field of passenger vehicles, automatic transmission (AT) is still the mainstream transmission structure. Most of the early automatic transmissions (AT) used a multi-stage planetary gear set structure, either with few gears or an overly complex structure. Later, the structure of the automatic transmission in which the combination of two shaft systems, spur gear sets and planetary gear sets began to appear. Chinese invention patent CN101275630B has just described such a multi-stage transmission with power shifting. [0003] In order to further reduce fuel consumption and improve driving dynamics, the vehicle requires more and smaller transmission gears. The purpose of reducing fuel consumption not only comes from the user's own economic needs, but also an important means to ac...
