Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but the present invention is not limited to the embodiments.

[0011] The electric actuator of the present invention is composed of at least two groups of electromagnetic clutches (three groups are described now). The gear change is completed by the electric actuator, that is, the electromagnetic clutch realizes the gear change, and the gear transmission mechanism realizes the speed change. The electromagnetic clutch includes the active part of the electromagnetic clutch, the left and right driven parts of the electromagnetic clutch, and the working coil, and the active part of the electromagnetic clutch is installed on the transmission output shaft and the intermediate shaft respectively. The left and right driven parts of the electromagnetic clutch are respectively connected with the corresponding gears in the gear box. The working coils are installed a...

Abstract

The invention discloses an automatic transmission for an electrical-control and electric-actuating mechanism for vehicles. Based on a transmission gear box for vehicles, an electric actuating mechanism is arranged in the transmission gear box and comprises at least two electromagnetic clutches, each electromagnetic clutch comprises an electromagnetic clutch drive part, a left electromagnetic clutch driven part, a right electromagnetic clutch driven part and a working coil, and the electromagnetic clutch drive part is respectively arranged on an output shaft and a middle shaft of the transmission. The invention can automatically change shift according to an operating command of a driver or vehicle controller, change the driving speed of the vehicles to enable the vehicles to achieve best dynamic property or economical efficiency, and have the advantages of simple structure, flexible construction, software control mode, low production cost and the like.

Description

Technical field: [0001] The invention relates to the technical field of vehicle engineering, in particular to an automatic transmission of an electronically controlled electric actuator for a vehicle. Background technique: [0002] At present, most of the automatic transmissions used on vehicles use electronically controlled hydraulic actuators, which are composed of a hydraulic torque converter, a planetary gear transmission mechanism and a hydraulic actuator system. The shifting gear is realized by hydraulically manipulating the gear combination. . The front end needs a hydraulic torque converter and a lock-up clutch, and there must be a hydraulic oil circuit with a complex structure and high precision requirements inside, so only a planetary gear transmission mechanism can be used. Control hydraulic actuator system, control frequency response characteristics are not good. Invention content: [0003] In order to solve the above existing problems, the present invention ...
