Abstract

The present invention discloses an AMT (automated mechanical transmission) actuator and an AMT transmission, and relates to the technical field of the transmission; in the present invention, the technical problem that the automated mechanical transmission actuator is relatively low in transmission efficiency and relatively large in abrasion is alleviated. The AMT actuator comprises a first motor,a first ball screw assembly, a first transmission assembly, a second motor, a second ball screw assembly, a second transmission assembly and a selector lever; the first ball screw assembly comprises afirst screw rod and a first nut; the first screw rod is in transmission connection with the first motor; the first nut is connected with the selector lever through the first transmission assembly; the second ball screw assembly comprises a second screw rod and a second nut; the second screw rod is in transmission connection with the second motor; the second nut is connected with the selector lever through the second transmission assembly; and a shifting finger is arranged on the selector lever and connected with a control mechanism of a transmission body. The AMT transmission comprises the transmission body, a TCU (transmission control unit) and the AMT actuator. The technical solution provided by the present invention has the advantages of high transmission efficiency, wear resistance and compact structure.

Description

technical field [0001] The invention relates to the technical field of transmissions, in particular to an AMT actuator and an AMT transmission. Background technique [0002] The electronically controlled mechanical transmission is based on the manual mechanical transmission, and an automatic actuator is added to replace the transmission that manually performs the gear shifting operation. There are mainly three types of AMT gear selection and shifting actuators: electro-mechanical, electro-hydraulic, and electro-pneumatic. [0003] The electromechanical actuator adopts a motor to drive the gear selection and shifting actuator, and converts the high-speed rotational motion output by the motor into the linear motion or back and forth swing required by the actual gear selection and shifting through different forms of reduction mechanisms. At present, the transmission efficiency of the electronically controlled mechanical actuator is low and the wear is relatively large. [000...
