Abstract

The invention discloses an ATM speed changer and a gear-selecting gear-shifting assembly used for the AMT speed changer. The gear-selecting gear-shifting assembly used for the AMT speed changer comprises a motor, a motor screw, a first poking block, a second poking block, a third poking block and a gear shifting guide piece; the first, second and third poking blocks are matched with the motor screw; the motor drives the motor screw to rotate; when being positioned at a locking position, the gear shifting guide piece is used for limiting the first, the second and the third poking blocks from rotating; when the gear shifting guide piece is positioned at an unlocking position, a corresponding gear shifting poking fork is suitable for limiting the third poking block from rotating and the gear shifting guide piece is separated from the first and second poking blocks, so that the third poking block is abutted against the first or second poking block. According to the gear-selecting gear-shifting assembly used for the ATM speed changer, power is provided for the gear selecting and gear shifting of the ATM speed changer by one motor, the structure is compact, the parts are less, the size is small, the whole machine configuration is convenient, the control is easy and the manufacturing cost is greatly reduced.

Description

technical field [0001] The present invention relates to the field of vehicles, in particular, to a gear selection and shifting assembly for AMT transmissions and an AMT transmission having the same. Background technique [0002] The existing operation mode is the electromechanical AMT transmission, the gear selection motor completes the gear selection of the AMT transmission by controlling the gear selection gear assembly of the gear selection assembly, and the gear shifting motor completes the gear shifting of the AMT transmission by controlling the shifting gear assembly of the shifting assembly. , the structure is complex, which is not conducive to the layout, and the difficulty of motor control is increased and the cost is high. SUMMARY OF THE INVENTION [0003] The present invention aims to solve one of the above-mentioned technical problems at least to a certain extent. To this end, an object of the present invention is to provide a gear selection and shifting assem...
