A manual gear selection mechanism for amt transmission testing

Abstract

The invention discloses a manual shifting mechanism for AMT gearbox testing, and relates to the technical field of testing shifting. The lever center piece, the universal ball auxiliary mounting seat installed on the top of the lever center piece and equipped with the lower universal ball seat, the upper universal ball seat installed on the top plate of the lower mounting seat, and the lever center piece, universal ball seat installed in sequence from bottom to top Joystick set to ball auxiliary mount, lower ball mount, lower mount, upper ball mount and shift gate. The present invention is provided with a gear shifting structure, and its lever center piece is positioned and coordinated with the gear shifting shaft, and the operator can drive the operating rod with one hand to limit the gear shifting groove, upper universal ball seat, lower universal ball seat and steering base. Under the position, the power is transmitted through the lever center piece, and the gear selection and shifting operation is performed accurately, which greatly increases the work efficiency of the operator and reduces the work intensity and danger of the operator.

Description

technical field [0001] The invention relates to the technical field of test gear shifting, in particular to a manual gear shifting mechanism used for gear shifting when an AMT gearbox is tested on a test bench. Background technique [0002] The automatic (AMT) transmission is a transmission device that can automatically shift gears according to the vehicle speed and engine speed relative to the manual transmission. The selector shaft is the actuator for the AMT transmission to shift gears , is also the core component for the realization of the variable speed function. In the assembly stage of the automobile gearbox assembly, the shifting mechanism is only finally configured in the vehicle production, but the shifting mechanism in the final configuration is not suitable for the shifting operation in the testing stage. [0003] When the AMT gearbox test is actually carried out on the test bench, two staff members are required to cooperate to select and shift gears through sim...
