Dry friction type double clutch of automatic transmission

Abstract

The invention discloses a dry friction type double clutch of an automatic transmission. Pressure plates of a clutch cover assembly includes a first pressure plate, a second pressure plate and a third pressure plate, and driven plate assemblies include a first driven plate assembly and a second driven plate assembly. Diaphragm springs of the clutch cover assembly include a first diaphragm spring and a second diaphragm spring, the second diaphragm spring is mounted on the first pressure plate, the first diaphragm spring is mounted on a clutch cover of the clutch cover assembly through a limiting column, and the second diaphragm spring and the clutch cover as well as the first diaphragm spring and the clutch cover are connected through an inner toothed plate and an outer toothed plate respectively. The inner toothed plate and the outer toothed plate are in contact with the clutch cover respectively and connectively through a plurality of bosses thereon. Automatic gapless gear shifting can be realized, power stagnation cannot occur, driving comfortability of a complete vehicle and economical efficiency in fuel conservation and consumption reduction are effectively improved, and the dry friction type double clutch has the advantages of fuel conservation and consumption reduction, high acceleration and automatic gear shifting.

Description

technical field [0001] The invention relates to the field of a motor vehicle clutch, in particular to a clutch applied to an automatic transmission. Background technique [0002] The traditional clutch cover assembly, because it is a single clutch, needs to be manually shifted during the gear shifting process, which will cause power stagnation, slowdown of vehicle speed, lag, large fuel consumption, and discontinuous vehicle speed during driving. , resulting in poor driving comfort and lack of dynamics. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a dry friction double clutch of an automatic transmission that can realize automatic gapless gear shifting without power stagnation and has automatic compensation function. [0004] In order to achieve the above object, the present invention provides the following technical solutions: the dry friction double clutch of the automatic transmission ...
