Embodiment Construction
[0037] Necessary Notes: In the text of this specification and all the drawings, the same or similar components and characteristic parts use the same reference signs, and only give necessary explanations when they appear for the first time. Likewise, the working mechanism or process of the same or similar mechanisms will not be described repeatedly. In order to distinguish the same components or feature parts arranged in symmetrical or corresponding positions, letters are added after the reference signs in this specification, and no letters are added when it refers to general description or no distinction is needed.
[0038] In view of the complete and detailed description of the space wedging friction connector, it has been recorded in the two basic patent applications combined as a whole above. Therefore, for the sake of brevity of description, this application only discusses the core of the invention before the formal description of AT. The space wedging type friction connec...

The invention relates to a hydraulic automatic transmission with space fit friction connectors, which comprises a transmission shell and a plurality of friction connectors used as gear shifting elements. Preferably, all of the friction connectors are space fit friction connectors. In addition, the hydraulic automatic transmission also comprises an operating mechanism fixedly connected to the transmission shell; and the operating mechanism is operably connected with the space fit friction connectors so as to connect or disconnect the space fit friction connectors. The hydraulic automatic transmission has the most obvious characteristics that all the friction connectors work in a self-excitation mode on the basis of the torque transferred by the friction connectors and the connecting or disconnecting operation of the friction connectors can be completed only by an electric / wire control trigger-type promote force without depending on a hydraulic system, so that the design and the structure are fundamentally and greatly simplified, the manufacturing and using cost is reduced and the energy consumption of the hydraulic automatic transmission is reduced.
Description
[0001] related application [0002] This application is a subordinate patent application of the applicant's basic patent application disclosed in patent documents WO2012 / 089131A1 and WO2011 / 000300A1, and this application claims the priority of Chinese patent application 201210242204.7 proposed by the applicant. The entire contents of the three prior patent applications of this publication are hereby incorporated by reference. technical field [0003] The invention relates to a speed change device in the field of mechanical transmission, in particular but not only to an automatic speed changer including a friction connector. Background technique [0004] As a common sense, in the world passenger car market, the installed rate reaches about 40%, including the hydraulic automatic transmission with hydraulic torque converter, or called AT, which has always been the absolute leader in the field of automatic transmission. And the dual-clutch automatic transmission, or DCT, which ...
