Embodiment Construction

[0016] The technical solutions of the present invention are further described in detail in the following embodiments given in conjunction with the accompanying drawings.

[0017] refer to figure 1 , 2 , this embodiment takes the automatic shift system of a four-speed transmission as an example. Its shift actuator consists of three shift gears (1, 8, 5), three shift racks (10, 11, 12) meshing with the three shift gears, and three shift motors (9, 7, 6) composition, the shift motor is a DC motor. There are three shift fork shafts (2, 3, 4) in the gearbox, and three shift racks (10, 11, 12) are respectively fixedly connected to the three shift fork shafts (2, 3, 4). Each shift gear (1, 8, 5) is meshed with a shift rack, and the shift motors (9, 7, 6) are respectively driven and connected to the shift gears (1, 8, 5). Three DC motors (9,7,6) are respectively connected with the described shift control system.

[0018] The change of the gear position is realized by the movemen...

Abstract

This invention relates to an electric controlled mechanic automatic speed variator shift system, which comprises shift execution structure and shift control system, wherein the said execution structure is composed of independent each shift fork current motor, shift gear, and shift gear bars, that is, each direct current motor is connected to one shift gear fixed on each fork axis shift gear bar and shift gear and each direct current motor is separately connected to the said shift control system.

Description

technical field [0001] The invention relates to a vehicle automatic transmission device, in particular to an electronically controlled electromechanical automatic transmission gear shifting system. Background technique [0002] With the rapid development of automobile technology, various forms of vehicle automatic transmission devices have emerged, mainly including: hydromechanical automatic transmission (AT), mechanical continuously variable transmission (CVT), and domestic and foreign are spending a lot of money in recent years The electro-mechanical automatic transmission (AMT) researched by force. In particular, the development of electronically controlled mechanical automatic transmissions is being paid attention to by major automobile factories because of its advantages of high fuel economy, low emission and protection of existing manual transmission production investment required by the development of the automobile industry. [0003] Electromechanical automatic tran...
